Answer:
26
Step-by-step explanation:
Okay so first, let's write out an equation:
36.26/49 = x/100
Then, multiply both sides by 100 to get the x isolated.
x = 74
100-74 = 26
So the percent decrease is 26
13 x 5 = 65
4 x 7 = 28
28 + 65 = 93
Your error is in you said 13 x 65 is 75
Answer:
true
Step-by-step explanation:
Answer:
y = -3x + 7
Step-by-step explanation:
The equation of a line
y = mx + c
y - intercept point y
m - slope of the line
x - intercept point x
c - intercept point of the line
Step 1: find the slope
m = y2 - y1 / x2 - x1
Given two points
( 1 , 4) ( 2 , 1)
x1 = 1
y1 = 4
x2 = 2
y2 = 1
insert the values
m = 1 - 4 / 2 - 1
m = -3/1
m = -3
y = -3x + c
Step 2: substitute any of the two points given into the equation of a line
y = -3x + c
( 1 ,4)
x = 1
y = 4
4 = -3(1) + c
4 = -3 + c
4 + 3 = c
c = 7
Step 3: sub c into the equation
y = -3x + 7
The equation of the line is
y = -3x + 7
