if y=x^2
all you have to do is plug in the numbers like for y it would be
4=x^2 it would be -2 and 2
Answer:
Step-by-step explanation:
to find the x-intercept:
Make y=0
0=-8x+4
8x =4
x=4/8
x=1/2
to find y-intercept:
Make x=0
y=-8(0) +4
y=4
Hope this helps!
Mark brainliest if you think I helped! Would really appreciate!
Answer:
25 because the 8 values must times with 7 and will get 56. when the ninth value added , let the ninth value as y , 56+y , the new mean is 9 . so it will be like this , 56+y over 9 times with 9
Answer: c=24
Step-by-step explanation: 15×3=45. 8×3=24. Just multiply both the numerator and denominator by 3.
Answer:
Width = 16 m
Length = 4 m
Step-by-step explanation:
The area of rectangular is 64m² the length of the pool is 12 m less that the width . The situation can be represented by the equation x
Area of a rectangle = Length × Width
L = W - 12
Hence:
64 = (W - 12) × W
64 = W² - 12W
W² - 12W - 64 = 0
Factor using
(W + 4)(W - 16) = 0
Width = 16m
Length = W - 12
Length = 16 m - 12 m
= 4 m
