Answer:
[tex]\boxed {\boxed {\sf m= - \frac{5}{4} }}[/tex]
Step-by-step explanation:
The formula for slope is:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
where (x₁, y₁) and (x₂, y₂) are the points the line passes through.
The line passes through (3,14) and (7,9). Therefore,
[tex]x_1=3 \\y_1=14 \\x_2=7 \\y_2=9[/tex]
Substitute the values into the formula.
[tex]m= \frac{9-14}{7-3}[/tex]
Solve the numerator.
[tex]m=\frac{-5}{7-3}[/tex]
Solve the denominator.
[tex]m= \frac{-5}{4}[/tex]
This fraction is reduced, so it is the answer.
The slope is equal to -5/4
What happens when a figure is dilated .
Answer:
A dilation is a transformation that produces an image that is the same shape as the original, but is a different size. A dilation that creates a larger image is called an enlargement. A dilation that creates a smaller image is called a reduction. A dilation stretches or shrinks the original figure.

You solve a system of two linear equations by substitution. Your work results in a third equation, which leads you to conclude that the system has infinitely many solutions. Which of the following could be the third equation?
The options are:
5=0
-4=-4
2y=14
3x+10=16
Decide whether n = 9 is a solution to
the equation 2+n=7. Write yes or no
Answer:
No. The answer would be n=5
Step-by-step explanation:
You have to subtract the 2 from both sides to cancel it out on the left side. so you would be doing 7-2, not 7+2

Answer:
8. s(-2) = 3, s(0) = 2, s(4) = 0
Look at the table for each of the values of x in s(x) and see what the y-value is. For example, for s(-2) you look at what y is when x = -2. It would be y = 3.
9. when x = -4, so s(-4)
Look through the table to find the row where y = 4. x would be -4.
10. -1
You can see that each time x goes up by 2, y goes down by 1. This means that the next row would say x = 6 and y = -1. The predicted value of s(x) is -1.
Amaka buys 4 rulers and a pencil and these cost the same as 2 rulers and 4 pencils. If a pencil cost #8, how much does a ruler cost?
Answer: ruler cost $12
Step-by-step explanation:
step 1
Let cost of ruler be represented as r
and cost of pencil be represented as p
we were given that
4 rulers and a pencil and these cost the same as 2 rulers and 4 pencils which is expressed as
4r + p = 2r+ 4p
and cost of pencil= $8
therefore
sTEP 2--- Solving
4r+ 8 = 2r+ 4 x8
4r+ 8 = 2r+ 32
4r - 2r= 32-8
2r= 24
r= 24/2 = r= $12
The sum of 6 times a number and 8 times another number is 12. The difference of those numbers is 9. What are the two numbers
Answer:
(x,y): (6 , -3) or (-30/7 , 33/7)
Step-by-step explanation:
6x + 8y = 12
x = y + 9 or y = x+ 9
if x = y+9
6*(y+9) + 8y = 12
14y = -42
y = -3 and x = 6
if y = x+9
6x + 8*(x+9) = 12
14x = -60
x = -30/7 and y = 33/7
Ty'Lil has $220 to spend on a membership to a new gym. The monthly fee is $15 and he must also pay $40 to join. How many months can he afford?
Answer: 12
Step-by-step explanation:
220-40=180
180/15=12
Answer:
11 months
Step-by-step explanation:
220 -40=180
Since you have to pay $40 to join you have to add $15 to that $40 for the monthly fee.
220-40-15=156
^ This equals one month worth of the membership.
220-40-15-15-15-15-15-15-15-15-15-15-15=0
So add up all the 15s and you have the number of months Ty ´Lil can afford.

The measure of one angle is thirteen less than five times the measure of another angle. The sum of the measures of the two angles is 140°. Determine the measure of each angle in degrees.
Answer:
The two angles are 25.5 and 114.5
Step-by-step explanation:
x = measure of one angle
5x - 13 = measure of the other angle {one angle is 13 less than 5 times the other}
x + 5x - 13 = 140 {sum of the two angles is 140}
6x - 13 = 140 {combined like terms}
6x = 153 {added 13 to each side}
x = 25.5 {divided each side by 6}
5x - 13 = 114.5 {substituted 25.5, in for x, into 5x - 13}

Answer: How to answer radical questions and such:
The most basic is to isolate one of the square roots, square both sides, and this will usually yield less square roots than when you started with. Keep repeating until you have no more square roots. This works pretty well in most cases, there are sometimes some tricks, arising from the particular problems themselves ways, which allow you to solve the equations much faster
The solving methods for Square root and radical equations are given below.
What is a radical equation?An equation wherein a variable is withinside the radicand of a thorough expression is referred to as a thorough equation. As usual, whilst fixing those equations, what we do to at least one aspect of an equation we ought to do to the alternative aspect as well. Once we isolate the radical, our approach could be to elevate each facet of the equation to the strength of the index. This will remove the radical.

Answer:
$324.00
Step-by-step explanation:
Increase the number by 8% of its value.
Percentage increase = 8% × 300
New value =
300 + Percentage increase =
300 + (8% × 300) =
300 + 8% × 300 =
(1 + 8%) × 300 =
(100% + 8%) × 300 =
108% × 300 =
108 ÷ 100 × 300 =
108 × 300 ÷ 100 =
32,400 ÷ 100 =
324
$24.. 8% of $300 equals 24 so the associate made $324 dollars in December. 24+300=324
