Answer:
y = 3x + 45 is the function equation of y intercept and slope.
The only option that fits is E, because:
f(10)=4×10+10=50
Answer: x=21
Step-by-step explanation:
To solve for x you must first combine you like terms on each side of the equal sign. So you problem will become 8x+1=22+7x. Then get your x on one side and your numbers on the other by taking the one away from the right side and 1 away from 22. Then take away 7 from the left side to cancel it out. Then take 7x away from 8x to leave you with x. making your answer x=21
4x+5y=7
y=3x+9
1) 4x+5(3x+9)=7 2) y=3(-2)+9
y= -6 +9
4x+15x+45=7 y=3
19x+45=7
19x= -38
x= -2
x is -2 and y is 3

If you take the 1/4, and the 8 (which can be re written as 8/1), and multiply them together, you get two.
1/4*8/1=2
