What are the intercepts of f(x)=5x-45

Answers

Answer 1

Answer: The y-intercept of f(x) = 5x - 45 would be -45, as that is what is represented in the equation. The way to find the x-intercept would be to solve the equation when f(x) = 0.

0 = 5x - 45
+ 45 + 45

45 = 5x
/5 /5
9 = x

And there we have it.
The intercepts of f(x) = 5x - 45 are as follows:

y-intercept = -45
x-intercept = 9

In baseball batting averages are expressed as decimal numbers if the player has had 8 hits out of 20 a bats what is his batting average and what percentage of the time does the player get a hit

Answers

To find the batting average divide the number of hits by the number of at bats.
Batting average = 8 / 20 = 0.400, which equals 40% of the time they get a hit.

A. 41
B. –7
C. –3
D. 25

Answers

When you are subtracting a negative, you treat it as if you are adding a positive. So 19-(-8) would be 19 + 8 which is 27. Then do the same thing with the 14, so instead of 27 -(-14) it's 27 + 14 which is 41. So your answer is 41. I hope this helps! XD

justin and tyson are beginning an exercise program to train for football season. Justin weighs 150 pounds and hopes to gain 2 pounds per week. Tyson weighs 195 pounds and hopes to lose 1 pound per week. if the plan works in how many weeks will the boys weigh the same amount. what will the weight be

Answers

It will take Justin and Tyson 15 weeks to both be 180 pounds. You just do 150+2*15=180 and then you would do the other one 195-1*15=180 and they both equal the same.

it will take 15 weeks for them to be the same weight.

Which of the following expressions shows the expression 1/2x+3−2/5x+1 in simplest form?

Hey there!

1/2x + 3 - 2/5x + 1

COMBINE the LIKE TERMS

= (1/2x - 2/5x) + (3 + 1)

1/2x - 2/5x = 1/10x

3 + 1 = 4

= 1/10x + 4

Therefore, your answer is: 1/10x + 4

Answer:

$\huge\boxed{(1)/(2)x+3-(2)/(5)x+1=(1)/(10)x+4}$

Step-by-step explanation:

$(1)/(2)x+3-(2)/(5)x+1\n\n=\left((1)/(2)x-(2)/(5)x\right)+(3+1)\n\n=\left((1\cdot5)/(2\cdot5)x-(2\cdot2)/(5\cdot2)x\right)+4\n\n=\left((5)/(10)x-(4)/(10)x\right)+4\n\n=(1)/(10)x+4$
