Answer: 4(x + 9) = 3x − 8 − 5
Step-by-step explanation:
The subtraction property of equality states that f a = b, then a − c = b − c. Subtracting 5 from both sides of the given equation gives 4(x + 9) = 4x − 8 − 5.
2x^2+12x-14=0 by completing the square
First factor 2 from the quadratic:
[tex]2x^2+12x-14=2(x^2+6x-7)[/tex]
Now complete the square:
[tex]x^2+6x-7=x^2+6x+9-16=(x+3)^2-16[/tex]
So we have
[tex]2x^2+12x-14=0\implies2(x+3)^2-32=0[/tex]
[tex]\implies2(x+3)^2=32[/tex]
Solve for x:
[tex](x+3)^2=\dfrac{32}2=16[/tex]
[tex]x+3=\pm\sqrt{16}=\pm4[/tex]
[tex]\implies x=-3+4=1\text{ OR }x=-3-4=-7[/tex]
and so the third option is correct.
Use K to write an equation, y=kx, for the relationship.

Someone wanna help on this one? The Chain Reaction bike shop is running a special that allows a family to rent all the bikes and equipment they need for an hourly rate and a nonrefundable $15 deposit. The Morales family can rent bikes for 2 hours for $57. The cost of the rental can be represented by a linear function where x represents the number of hours the bikes are rented and y represents the total cost of the rental. What is the equation here and what are the slope and y-intercept?
Answer:
y=21x+15, where 21 is the hourly rate and the slope, 15 is the non-refundable deposit, and y is the total amount payedStep-by-step explanation:
the slope is the hourly rate, the y int is the deposit of 15$
thus,
to find the slope, we can use the equation:
57=m*2+15
42=2m
m=42/2
m=21
thus, the whole equation is:
y=21x+15, where 21 is the hourly rate and the slope, 15 is the non-refundable deposit, and y is the total amount payed
calculate the area of a circle with a diameter of 8 feet
Answer: 50.27
Step-by-step explanation:
Area = pi r^2
= pi x 16
Answer:
50.265 [tex]ft^{2}[/tex]
Step-by-step explanation:
The formula of the area of a circle is [tex]\pi r^{2}[/tex] and the diameter is double the amount as the radius, so the radius would be 4 feet. 4 squared is 16. Multiply that by pi to get your answer, 50.265[tex]ft^{2}[/tex].

Answer:
Because all consecutive angles in a parallelogram are supplementary, m∠SVU = 180 - 57 = 123°.
Answer:
Step-by-step explanation:
In a parallelogram, sum of adjacent angles is 180
∠TSV + ∠SVU = 180
57 + ∠SVU = 180
∠SVU = 180 - 57
∠SVU = 123°

Which is true about the line whose equation is y + 2 = 0?
Answer:
The y-intercept is -2
Step-by-step explanation:
Based on the equation y + 2 = 0 (y = -2), you can eliminate all answers except for the second one. This is because, the y is the horizontal line, while the x is the vertical line. The value of x does not always equal the value of y, only sometimes. Finally, the slope of y = -2 is 0, not undefined. However, the slope of x = -2 is undefined.
Suppose you have one pyramid with a base that is 10 meters long and 10 meters wide with a slant that is 15 meters. Now, if the length of the base is
Answer:
The difference between area of pyramids is 125 sq.m.
Step-by-step explanation:
Length of base = 10m
Breadth of base = 10 m
Slant height = 15 m
Area of pyramid = Area of 5 bases
Area of pyramid = [tex]\frac{1}{2} \times 10 \times 15+\frac{1}{2} \times 10 \times 15+\frac{1}{2} \times 10 \times 15+\frac{1}{2} \times 10 \times 15+10 \times 10[/tex]
Area of pyramid = 400 sq.m.
Now the length of base is increased to 15
Length of base = 15m
Breadth of base = 10 m
Slant height = 15 m
Area of pyramid = Area of 5 bases
Area of pyramid =[tex]\frac{1}{2} \times 15 \times 15+\frac{1}{2} \times 15 \times 15+\frac{1}{2} \times 10 \times 15+\frac{1}{2} \times 10 \times 15+10 \times 10[/tex]
Area of new pyramid = 525 sq.m.
Difference between area of pyramids=525 sq.m. - 400 sq.,. = 125 sq.m.
Hence The difference between area of pyramids is 125 sq.m.
16. Does this shape show thirds?
Explain.
Answer:
No
Step-by-step explanation:
This shape does not show thirds. Although the shape is cut up into 3 shapes, the shapes are not equal. Imaging a cake... would you be happy if your friend got the rectangle, but you got the square. Cutting something into thirds is the same way. They all need to be equal.
Answer:
No, It shows 1/2
Step-by-step explanation:
The small squares would constitute to a total of 4, so it shows 2/4 which is 1/2

Solve by taking the square root of both sides 3(x-1)^2-162=0
a. x = -1 - 3 sqrt 6 or -1 + 3 sqrt 6
b. x = 1 - 3 sqrt 6 or -1 + 3 sqrt 6
c. x = -1 - 3 sqrt 6 or 1 + 3 sqrt 6
d. x = 1 - 6 sqrt 6 or 1 + 6 sqrt 6
Answer:
see explanation
Step-by-step explanation:
Given
3(x - 1)² - 162 = 0 ( add 162 to both sides )
3(x - 1)² = 162 ( divide both sides by 3 )
(x - 1)² = 54 ( take the square root of both sides )
x - 1 = ± [tex]\sqrt{54}[/tex] = ± 3[tex]\sqrt{6}[/tex] ( add 1 to both sides )
x = 1 ± 3[tex]\sqrt{6}[/tex]
x = 1 - 3[tex]\sqrt{6}[/tex] or x = 1 + 3[tex]\sqrt{6}[/tex]

(SAT Prep) In the given figure, the reflex angle ∠DOB has measure of 3.5y while the measure of ∠AOD is y. Find the measure of the non-reflex ∠DOB in degrees.
Answer:
252°
Step-by-step explanation:
In the figure attached, the diagram is shown. There, we can see that
∠DOB = ∠AOD + ∠AOC + ∠COB
Replacing with the equivalences: ∠DOB has a measure of 3.5y, the measure of ∠AOD is y, and ∠AOC + ∠COB measure 180°, we get:
3.5y = y + 180°
3.5y - y = 180°
2.5y = 180°
y = 180°/2.5
y = 72°
Therefore, ∠DOB = 3.5*72° = 252°
Answer:
108 degrees
Step-by-step explanation:
m∠DOB=m∠AOD+m∠AOC+m∠COB And then we substitute, m∠DOB=3.5y, m∠AOD=y, m∠AOC+m∠COB=180 degrees. So the equation will then be 3.5y=y+180 degrees
y= 72
m∠DOB=3.5 x 72 m∠DOB=252 degrees, this is the reflex angle.
360-252=108 degrees, the non-reflex m∠DOB= 108 degrees
How many solutions does the equation have 4p + 1 = 49 - 7
Answer:
so one solution
Step-by-step explanation:
4p+1=49 - 7
minus 1 to -7= -8
4p= 49-8
4p=41, divided by 4 and you'll get a decimal, 10.25
Answer:
1 solution if solving for p.
Step-by-step explanation:
If solving for p:
4p+1=49-7
4p+1=42
Subtract 1 from both sides
4p=41
Divide both sides by 4
p=10.25
There is only one solution, 10.25
But I've seen this question on a Quizizz and the answer was no solutions. I don't think that's correct but... might be because the question didn't ask to solve for p.

Reset
Next
Answer:
The chart type described is the OHLC chart.
Step-by-step explanation:
An OHLC chart is a kind of bar-chart that displays open, high, low, and closing prices for each period. OHLC charts are beneficial since they demonstrates the four major data values over a period, with the closing price being reflected as the most significant by traders.
The chart type is valuable since it can represent increasing or decreasing movement. When the open and close are far-apart it represents strong movement, and when the open and close are close together it represents wavering or weak movement. The high and low displays the full price range of the period, useful in evaluating instability.
Thus, the chart type described is the OHLC chart.

Jenna saves $2,500 per year in an account that earns 10% interest per year, compounded annually. Jenna will have saved in 30 years. Her account balance is a result of Jenna’s .
Answer:
$43,625
Step-by-step explanation:
Hello,
The question is a direct application of compound interest and we'll approach this question using the formula of compound interest.
A = P(1 + r/n)^nt
A = compound interest
P = principal
r = rate of the interest
n = number of times compounded
t = time interval for the money to be compounded.
Data;
A = ?
P = $2,500
r = 10% = 0.1
n = 1 (since it's compounded annually)
T = 30 years
A = 2,500 [1 + (0.1 / 1)]^(1 × 30)
A = 2,500 × [1 + 0.1]³⁰
A = 2,500 × 1.1³⁰
A = 2,500 × 17.45
A = $43,625
In 30 years, Jenna would've saved $43,625

Converse, inverse, contrapositive or syllogism
Thanks
Answer:
7. Contrapositive
8. Converse
9. Inverse
Step-by-step explanation:
Contrapositive is the flipping of the pos/neg and the clauses.
- EX: If it rains today, the ground will be wet -> If the ground is not wet, it did not rain today
Converse is the switching of the clauses
- EX: If I just ate mac and cheese, I am happy -> If I am happy, I just ate mac and cheese
Inverse is swapping the positive/negative (not)
- EX: If I am hungry, I want food -> If I am not hungry, I do not want food
Hope this helps!
