Answer:
-2.8
Step-by-step explanation:
Gradient/slope = (change in y / change in x)
= == -2.8
If he gets a hit 25% of the time then you just do 1/4 of 500. which is 125 hits out of 500
First number = x
Consecutive number = x+1
"squares differ by 31" means to square both numbers and subtract them:
(x+1)^2 - (x)^2 = 31
x^2+2x+1 - x^2 = 31
2x+1 = 31
2x = 30
x = 15 (first number)
x+1 = 15+1 = 16 (consecutive number)
There is no image or equation that can be read There for this question is imcomplete.
The value of f(x) is 13, when x = 10
<h3>What are functions?</h3>
Functions are used to represent equations, graphs and ordered pairs
The equation of the function is given as:
When x =10, the equation becomes
Divide 10 by 2
Add 5 and 8
Hence, f(x) is 13, when x = 10
