Point slope is in the form
(y - y1) = m(x - x1)
where x1 and y1 are the coordinate of any point on the line, and m is the slope
The others do not work
Answer:
B.
Step-by-step explanation:
This is the point-slope form:
y - y1 = m(x - 1) where m = the slope.

Above are two different models of the same triangular-shaped garden. If the height of the model on the left is 15 cm, what is the height of the model on the right?
Answer: The height of the model on the right is 22.5 cm .
Step-by-step explanation:
We can see that , the given different models of the same triangular-shaped garden are similar.
For the first model 1 cm = 3.75 m
whereas for the second model 1 cm = 2.5 m
Now , the constant rate of proportion for this (k) = [tex]\dfrac{3.75}{2.5}=\dfrac{375}{250}=1.5[/tex]
Now , if height of the model on the left is 15 cm , then the height of the model on right = 15 x k
= 15 x 1.5
= 22.5 cm
Hence, the height of the model on the right is 22.5 cm .
Answer:
30 cm

What is the value for x?
Enter your answer in the box.
x =
Answer:
8
Step-by-step explanation:
because we know its an isosceles triangle angle A and C will both be the same and since we know A = 69 C will also be 69. we also know that angles in a triangle add to 180 so take away the two 69s from the 180 to get 42
then we work backwards if its 5x + 2 then we need to do 5x - 2 to get 40 then divide it by 5 to get your answer 8!

What are the dimensions of the vertical cross section of the right rectangular prism? Note that the figure is not drawn to scale.
Which of the following two-dimensional figures shows the dimensions of the vertical cross section?
ОА.
Answer:
option A
Step-by-step explanation:
From the picture, we can see that:
The height of the vertical cross section is the same as the height of the prism, that is, 4 inches.The base of the vertical cross section is the same as the width of the prism, that is, 8 inches.Evaluate: g(4):g(x) = 8x2 + 9x - 7
Answer:
g(4) = 157
Step-by-step explanation:
g(x) = 8x^2 + 9x - 7
Let x =4
g(4) = 8 * 4^2 +9*4 -7
=8*16 +36 - 7
=128+36-7
=157
Answer:
157
Step-by-step explanation:
g(x)=
[tex]{8x}^{2} + 9x - 7[/tex]
g(4) =
[tex]8( {4})^{2} + 9(4) - 7 \\g(4) = 8 \times 16 + 36 - 7 \\ g(4) = 128 + 29 \\ g(4) = 157[/tex]

n ≥ - 5
The symbol means that n can equal - 5 and values greater than - 5
Values greater than - 5 are to the right of - 5 on the number line.
- 4.5 and - 3 are to the right of - 5, thus greater than - 5
The set of values which make the inequality true are

Find the equation of the line through the point (6, -1) that is perpendicular to the line with equation y =1/2x-12
Answer:
y + 1 = -2/1 (x - 6)
Step-by-step explanation:
The above equation is written in point slope from. To find the slope of a line perpendicular to another line all you have to do is find the opposite reciprocal to the slope of the original line. The original line's slope is 1/2, the reciprocal is 2/1 and to create the opposite reciprocal you have to change the sign of the slope, so the new slope is -2/1. To finish the rest of the equation you plug in the points given to you in the question.
Answer:
Step-by-step explanation:
First, since the line is perpendicular to the given one, the slopes are negative reciprocals. The slope of the equation we must write is -2.
Now, we can set up point slope form:
y-y1 = m(x-x1)
y + 1 = -2(x - 6)
Now, we can change that to slope intercept form:
y + 1 = -2(x - 6)
y + 1 = -2x + 12
y = -2x -11

Answer:
On the second step there is a mistake. You have to multiply 2 times 2 before you add the five
Answer:
See below;
Step-by-step explanation:
We are given the following;
5 + [ 2 * 2 + 5 ], ⇒ add 2 and 5
5 + [ 2 * 7 ], ⇒ multiply 2 by 7
5 + 14, ⇒ combine like terms
Solution; 19
Now as we can see from the first ⇒ second step the process as to simplify the expression 5 + [ 2 * 2 + 5 ] further, was by adding 2 and 5. Of course by PEDMAS, it would be that multiplication takes place before that of addition, so that it should have been that 2 was multiplied by 2 first!
Solution below;
Steps | |
| 5 + [ 2 * 2 + 5 ] |
X | 5 + [ 2 * 7 ] |

I need help finding out what properties were used in this equation, 4(x+5)=9x+4x-34
Answer:
Step-by-step explanation:
4(x+5)=9x+4x-34
4x + 4*5 = 9x + 4x - 34 {distributive property}
4x + 20 - 4x = 9x + 4x - 34 - 4x {subtraction property of equality}
20 = 9x - 34
20 + 34 = 9x - 34 + 34 {Addition property of equality}
54 = 9x
54/9 = 9x/9 {division property of equality}

Find the area of circle x that has a radius XY at coordinates X = (0,2) and Y = (3,2). Round to the nearest hundredth place.
Answer: 28.27
Step-by-step explanation:
Area of circle = pi * r^2
Subtract either the x coordinates or y coordinates by each other to find the length of the radius. In this case, the x coordinates have a distance when you subtract.
2 - 2 = 0
3 - 0 = 3
The radius is 3
3^2 = 9
So, the area of the circle is 9 * pi
(9)pi = 28.27433388230814
To the nearest hundredth, the area of the circle is 28.27

Compare Mr. Nicholson’s potential income as an employee for the company for three years and nine years. Should time play a factor in his decision regarding contractual salary increases? Use complete sentences to explain your answer.
Answer:
Yes, time play a factor in his decision, because after 3 years, option a is better, but after 9 years, option b is better.
Step-by-step explanation:
The following information is missing:
Mr. Nicholson accepts a job that pays an annual salary of $60,000. In his employment contract, he is given the option of choosing a) an annual raise of $3,500 or b) an annual raise of 5% of his current salary.
The function that describes each situation is:
a) f(x) = 60,000 + 3,500*(x-1)
b) f(x) = 60,000*1.05^(x-1)
where x represents years and f(x) his salary.
Mr. Nicholson’s potential income for three years and nine years for each situation are:
a) f(3) = 60,000 + 3,500*(3-1) = $67,000
f(9) = 60,000 + 3,500*(9-1) = $88,000
b) f(3) = 60,000*1.05^(3-1) = $66,150
f(9) = 60,000*1.05^(9-1) = $88,647

What did you find as the mean average temperature in New York City and San Francisco?
Answer:
The average temperatures were:
New York City: 63San Francisco: 64Step-by-step explanation:
Remember that, the average is obtained in the form below:
Average = The sum of all the values / the number of values.In this case, the number of values is 12 because are the number of months in the year. The sum of values is shown below for each case:
Average temperature in New York City = (39 + 42 + 50 + 61 + 71 + 81 + 85 + 84 + 76 + 65 + 55 + 47) / 12 = 63. Average temperature in San Francisco = (57 + 60 + 62 + 63 + 64 + 67 + 67 + 68 + 70 + 69 + 63 + 58) / 12 = 64.I don't add units because the table doesn't specify if they are Celsius, Fahrenheit, or others.
Graph y=3/4 x + 2. What is the slope?
Answer:
3/4
Step-by-step explanation:
The given equation is in the form of y=mx+b
This is where m is the slope, and b is the y intercept.
This said, the slope of the equation is 3/4.
I will attach an image of the graph. I put the equation in a graphing calculator.
If you need to graph by hand, first plot the y intercept, (0,2) and then use the slope to find more points. Then, connenct the points with a ruler.
The image you attached is not the graph of y=3/4x+2, it is the graph of y=5.
It's slope is equal to 0.
Which point on the number line best represents the approximate value of
√23
Answer: Q
Step-by-step explanation: the 23 thing simplified would be 4 and a bunch of decimals. Q is the answer on four, and the 23 thing is closest to four, so Q would be the correct answer.
Number lines are used to represent numbers at regular interval.
[tex]\sqrt{23}[/tex] is represented by point Q
The number is given as:
[tex]\mathbf{Number = \sqrt{23}}[/tex]
Take square root of 23
[tex]\mathbf{Number = 4.79583152331}[/tex]
The above equation means that: the square root of 23 is between 4 and 5, and it is closer to 4.5 than 5.
The point on the number line that represents the above highlight is point Q.
Hence, [tex]\sqrt{23}[/tex] is represented by point Q

Answer:
140
Step-by-step explanation:
Angle 4 is congruent to angle 2 by corresponding angles postulate. Therefore, angle 2 is also 40. Angle 2 and angle 3 are supplementary, or add up to 180 because they are on a straight line. 140 and 40 add up to 180 so angle 3=140 degrees

if tan theta=3/4, find sin theta
Answer:
sin(theta)=3/5
Step-by-step explanation:
tan(theta)=3/4
sec^2(theta)=1+tan^2(theta)=1+(3/4)^2=1+9/16=(16+9)/16=25/16
sec(theta)=square root of(25/16)=5/4
sec(theta)=1/cos(theta)=5/4
cos(theta)=4/5
sin^2(theta)=1-cos^2(theta)=1–16/25=(25–16)/25=9/25
sin(theta)=3/5
So
sec(theta)=5/4
sin(theta)=3/5
