Answer:
I'm guessing G
Step-by-step explanation:
Let x be the number of ordinary cars
Let y be the number of SUV's
The difference between the number of ordinary cars and the number of suvs is 17.
So x-y=17 ----> first equation
The number of ordinary cars is larger than the number of sport utility vehicles by 77.3%.
ordinary cars = SUV + 77.3% of SUV
x = y + 0.773y
x = 1.773y
Now we solve for y
We plug in x=1.773y in first equation
1.773y - y=17
0.773y = 17
y = 21.9922
Number of SUV's = 22
Answer:
b
-28/9
Step-by-step explanation:
5+9b
-23
5+9b=-23
9b=-28
b=-28/9
Answer:
(7w + 9x)(7w - 9x)
Step-by-step explanation:
Given expression;
49w² - 81x²
Now to solve the problem;
49w² - 81x² = 7²w² - 9²x²
Using differences of two squares;
x² - y² = (x + y)(x - y)
So;
7²w² - 9²x² = (7w + 9x)(7w - 9x)
Answer:
y = -
x-7
Step-by-step explanation:
y=mx+b where m = the slope and b = the y intercept
the slope = change over y/change over x = (5-(-3))/(-9-(-3))=(5+3)/(-9+3)=8/(-6)=4/(-3)
y=-4/3x+b
plug in one of the points (it can be either)
-3=-4/3(-3)+b
-3=4+b
b=-7
y=-4/3x-7
