Answer:
y= 7/9x -17/9
Step-by-step explanation:
(5,2) (-4,-5)
slope intercept of a line is
y = mx +b
m = y2-y1/ x2-x1
= -5-2/ -4-5 = -7/-9
=7/9
if the line is passing through (5,2)
2= 7/9(5)+ b
2=35/9 +b
b = 2-35/9
b= -17/9
y= 7/9x -17/9

Step-by-step explanation:
A large rectangle is made up of nine identical rectangles whose longer side equals 10. What is the area of the large rectangle?
==========================================================
Explanation:
Refer to the diagram below.
A small rectangle has its longer side equal to 10 and its shorter side is x, which is some real number on the interval 0 < x < 10.
Across the top, the two sides of length 10 add to 20. So the larger rectangle has a horizontal dimension of 20 units.
The vertical side of the larger rectangle is x+10+x = 2x+10 units
The area would be
area = length*width = 20(2x+10) = 40x+200
Each of the nine smaller rectangles has area of length*width = 10x. Since we have 9 identical copies, the smaller rectangle areas must add to 9*10x = 90x
---------------
Equate those two expressions and solve for x
90x = 40x+200
90x-40x = 200
50x = 200
x = 200/50
x = 4
So each smaller rectangle has area of 10*x = 10*4 = 40 square units. In total, the nine smaller rectangles combine to an area of 9*40 = 360 square units
Note how x = 4 leads 40x+200 to result in 360 as well.

i didn't pay attention to the class
Answer:
x=2
Step-by-step explanation:
Let's solve your equation step-by-step.
Step 1: Simplify both sides of the equation.
12=2x+4x
12=(2x+4x)(Combine Like Terms)
12=6x
12=6x
Step 2: Flip the equation.
6x=12
Step 3: Divide both sides by 6. 6x/6=12/6
x=2
Hope you found this helpful and have good day (.
Answer:
2
Step-by-step explanation:
plus the like-terms (x plus x): 2+4
so 12=6x. get 6 out of the x-term. X is the unknown number being multiplied by 6. To get it to the other side, divide the numbers. So: 12/6=x and 12/6 is 2. so x=2.

What is the decimal equivalent of 4/5
Answer:
0.8
Step-by-step explanation:
to find the decimal equivalent we must get the denominator to 100
to do that we must multiply it by 20, 4/5 * 20/20 is 80/100
80/100 is also 80%, which is also 0.80 (which can be simplified to 0.8)

The amount of change is:
889 - 104 = 785The time difference in years:
2017 - 2012 = 5The annual rate of change is the ratio of the difference in amount to the time difference:
785/5 = 157Help!!!!!!!!!!!!!!!!!!!!!!!!
Answer:
x = 32
Step-by-step explanation:
The angle above 72° is 108° because they are supplementary angles, meaning they add up to 180°. Then we can set the equation 108° = (3x + 12)° because they are alternate interior angles, meaning that they are the same. So then we just solve for x.
108 = (3x + 12)
108 - 12 = 3x
96 = 3x
96 / 3 = x
32 = x

Answer:
y = -3x + 14Step-by-step explanation:
Given line:
y = 1/3x - 2/5Perpendicular lines have negative-reciprocal slopes.
We will have a line:
y = -3x + bUse the coordinates of the given point to find the value of b:
-1 = -3(5) + b-1 = - 15 + bb = 14So the line is:

A water tank in Stewart's
home had a small, steady
leak.
Loss of 1 3/5 mL in 10 min.
a. Use a complex fraction to
represent the change in the
volume of water in 1 minute.
___ milliliters
10 minutes
b. Simplify the complex fraction to find the change in the volume of water in the tank in 1 minute.
The change in the volume of water in 1 minute is a decrease of 0.16 milliliters.
Since a water tank in Stewart's home had a small, steady leak loss of 1 3/5 mL in 10 min, to find the change in the volume of water in 1 minute, the following calculation must be performed:
The total leak must be calculated and divided by the 10 minutes duration. 3/5 = 0.6 1 + 0.6 = 1.6 1.6 / 10 = 0.16
Therefore, the change in the volume of water in 1 minute is a decrease of 0.16 milliliters.

Answer:
<R = 30
LM = 6 sqrt(3)
Step-by-step explanation:
Since the figures are congruent
<R = < L
<S = <M
< T = <N
RS = LM
ST = MN
RT = LN
<L = 30 so <R = 30
RS = 6 sqrt(3) so LM = 6 sqrt(3)
The manager of a food court estimates that he needs 7 pretzels for every 20 people who attend a hockey game. What constant of proportionality relates the number of pretzels to people?
A. 0.35

D. 140
Answer:
a) 0.35
Step-by-step explanation:
The manager of a food court estimated that he needed 7 pretzels for every 20 people who attend that hockey game. This means that 20 people need/require to have 7 pretzels. 20 people= 7 pretzels.
