Answer:
x=31/14
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
−4x+1=−9x−16+9x+16
−4x+1=−9x+−16+9x+16
−4x+1=(−9x+9x)+(−16+16)(Combine Like Terms)
−4x+1=0
−4x+1=0
Step 2: Subtract 1 from both sides.
−4x+1−1=0−1
−4x=−1
Step 3: Divide both sides by -4.
−4x−4=−1/-4
x=1/4

What is the slope of a line perpendicular to the line whose equation is
10x - 12y = -24. Fully reduce your answer.
Answer:
The slope of the perpendicular line is [tex]-\frac{6}{5}[/tex]
Step-by-step explanation:
The form of the linear equation is y = m x + b, where
m is the slope of the lineb is the y-interceptThe product of the slopes of the perpendicular lines is -1. which means if the slope of one of them is m, then the slope of the other is [tex]-\frac{1}{m}[/tex]∵ The equation of the given line is 10x - 12y = -24
→ We need to form this equation as the form above to find m
→ Subtract 10x from both sides
∵ 10x - 10x - 12y = -24 - 10x
∴ - 12y = -24 - 10x
→ Divide both sides by -12
∴ [tex]\frac{-12y}{-12}=\frac{-24}{-12}-\frac{10}{-12} x[/tex]
∴ y = 2 - ([tex]\frac{-5}{6}[/tex]) x
→ Remember that (-)(-) = (+)
∴ y = 2 + [tex]\frac{5}{6}[/tex] x
∵ y = m x + b
∴ m = [tex]\frac{5}{6}[/tex]
∴ The slope of the given line is [tex]\frac{5}{6}[/tex]
→ To find the slope of the perpendicular line reciprocal it and change
its sign
∵ The reciprocal of [tex]\frac{5}{6}[/tex] is [tex]\frac{6}{5}[/tex]
→ Change its sign from + to -
∴ The slope of the perpendicular line is [tex]-\frac{6}{5}[/tex]
The slope of the line perpendicular to the line whose equation is
10x - 12y = -24 is - 6 / 5
The slope intercept form is represented as follows;
y = mx + b
where
m = slope
b = y-intercept
Therefore,
10x - 12y = -24
10x + 24 = 12y
12y = 10x + 24
divide through by 12
12y / 12 = 10 / 12 x + 24 / 12
y = 5 / 6 x + 2
The slope of this equation is 5/6.
For a line perpendicular to another line the product of there slope is negative 1. Therefore,
m₁m₂ = -1
m₁ 5/6 = -1
m₁ = - 6 / 5

A publisher needs to send many books to a local book retailer and will send the books in a combination of small and large boxes. Each small box can hold 30 books and each large box can hold 55 books. A total of 10 boxes were sent which can hold 375 books altogether. Write a system of equations that could be used to determine the number of small boxes sent and the number of large boxes sent. Define the variables that you use to write the system.
Answer: Number of small boxes = 7, Number of large boxes =3
Step-by-step explanation:
Let x= Number of small boxes , y = Number of large boxes.
As per given , 30x+55y=375 (i)
x+y=10 (ii)
Multiply (ii) by 30, we get
30x+30y=300 (iii)
Eliminate (iii) from (i), we get
25y=75
⇒ y= 3 [Divide both sides by 25]
Put y=3 in (ii), we get
x+3=10 ⇒ x=7
Hence, Number of small boxes = 7, Number of large boxes =3

A particular plant root grows 1.5 inches per month. How many centimeters is the plant root growing per month? (1 inch = 2.54 centimeters). 0.59 centimeters 1.69 centimeters 3.81 centimeters 4.04 centimeters
Answer:
The plant root grows 3.81 centimeters per month.
Step-by-step explanation:
From Physics, we remember that an inch equals 2.54 centimeters. Given that a particular plant root grows 1.5 inches per month, we proceed to make a quick conversion to calculate its value in centimeters per month:
[tex]x = 1.5\,\frac{in}{mo}\times \frac{2.54\,cm}{1\,in}[/tex]
[tex]x = 3.81\,\frac{cm}{mo}[/tex]
The plant root grows 3.81 centimeters per month.

A flower seed was planted 12 inches underground. It began growing 4 inches every week.
Answer:
12 + 4x
Step-by-step explanation:
It already had a starting point of 12 inches. So we add 12 to its height. Then we have 4x, x representing the number of weeks that have passed, and 4 meaning that it is growing 4 inches every week. This is why the answer is 12+4x in case you are looking for an expression

Lisa purchased a prepaid phone card for $30. Long distance calls cost 13 cents a minute using this card. Lisa used her card only once to make a long distance call. If the remaining credit on her card is $26.49, how many minutes did her call last?
Answer:
27minutesStep-by-step explanation:
Firstly, let us calculate the amount spent
amount spent=30-26.49
amount spent=3.51
the expression for the total amount spent is given as
y=c-mx
let us convert 13cents to dollar= $0.13 extra charge per minute
we can see that x is the number of minutes
therefore
26.49=30-0.13x
26.49-30=-0.13x
-3.51=-0.13x
x=3.51/0.13
x=27 minutes
the last call was 27minutes

The triangles below are similar.
therefore x = ?
Answer:
x = 6.
Step-by-step explanation:
JK = JG + GK = 6 + 4 = 10
Scalar factor(k) = JK/JG
k = 10/4 = 5/2
Scalar factor (k) = JL/GH
5/2 = x/15
5 × x = 2× 15
5x = 30
hence x = 6
When playing many games, players must roll a pair of dice and find the sum of the two numbers rolled. With two dice, there are 11 possible sums ranging from 2 through 12. What is the probability that a player will roll a sum of 11 on his first roll of two dice? Express your answer as a common fraction.
Answer:
[tex]Probability = \frac{1}{18}[/tex]
Step-by-step explanation:
Given
[tex]Dice = 2[/tex]
Required
Probability of getting sum of 11
First, we need to list out the sample space;
Represent the first dice with S1 and the second with S2
[tex]S_1 = \{1,2,3,4,5,6\}[/tex]
[tex]S_2 = \{1,2,3,4,5,6\}[/tex]
Represent the Sum of the outcome with S
So, the new sample space is the sum of outcome of S1 and S2
So, S is as follows:
[tex]S = \{2,3,4,5,6,7,3,4,5,6,7,8,4,5,6,7,8,9,5,6,7,8,9,10,6,7,8,9,10,11,7,8,9,10,11,12\}[/tex]
Represent the number of sample space with n(S)
[tex]n(S) = 36[/tex]
To determine the probability of outcome of 11, we need to list out the number of outcomes of 11.
Represent this with n(11)
From the sample space above,
[tex]n(11) = 2[/tex]
The required probability is then calculated as thus:
[tex]Probability = \frac{n(11)}{n(S)}[/tex]
[tex]Probability = \frac{2}{36}[/tex]
Simplify to the least term
[tex]Probability = \frac{1}{18}[/tex]

A line passes through the point (-2,-9) and is parallel to 5x - y = 7. What is the equation of the line?
Answer:
y = 5x + 1
Step-by-step explanation:
5x - y = 7
y = 5x - 7
Gradient = 5
Gradient of the line passing through point (-2,-9)
= 5
i.e it is parallel to line 5x - y = 7
Equation of the line is given as:
y - (-9) = 5(x - (-2))
y + 9 = 5x +10
y = 5x + 1
y=5x+1
What is slope in straight line?
Generally, the slope of a line gives the measure of its steepness and direction. The slope of a straight line between two points says (x1,y1) and (x2,y2) can be easily determined by finding the difference between the coordinates of the points. The slope is usually represented by the letter 'm'.
y-y1=m(x-x1)
mm1=-1
Given line,
5x-y=7
y=5x-7
slope, m=5
Since, the new line that passes through the point (-2,-9) is parallel to the line 5x-y=7, the slope of the new line will be the same.
Therefore, slope of the new line will be = 5
Now, equation of line is
y-y1=m(x-x1)
Putting the values,
y-(-9)=5(x-(-2))
y+9=5(x+2)
y+9=5x+10
y=5x+1
therefore, our line equation is y=5x+1

Melissa was recording the heights of 4 flowers in her garden. The rose bush grew 12 inches in 1 month, the daisies grew 5 inches in 2 weeks, the tulips grew 8 inches in 3 weeks, and the daffodils grew 3 inches in 1 week. Which flower grew at the slowest rate?
Answer:
Daisies flower grows the slowest
Step-by-step explanation:
We are given;
Rate of growth of rose bush; 12 inches in 1 month.
1 month = 4 weeks.
Thus, we have; 12 inches in 4 weeks.
In 1 week, it grows; 12/4 = 3 inches per week
Rate of growth of daisies; 5 inches in 2 weeks. Thus, in 1 week, it grows by; 5/2 = 2.5 inches per week.
Rate of growth of tulips; 8 inches in 3 weeks. In one week, it grows by; 8/3 = 2.67 inches per week
Rate of growth of daffodils; 3 inches in 1 week = 3 inches per week
Looking at all the rates above, the slowest is 2.5 inches per week. This is for daisies.
