Answer:
Step-by-step explanation:
a^2 + b^2 = c^2
6 = b
c= 8
a=?
now u just replace
a^2 + 6^2 = 8^2
a^2 + 32 = 64
a ^2 = 64-32
a^2 = 32

a = 5.65685424949
if you rounded
a = 5,7
Answer:
25.375
Step-by-step explanation:
17.50×45%=7.875
17.50+7.875=25.375 new price
The answer is 7.50X =y because he sells each shirt for 7.50 than you times that to the amount of shirts he sold but we don’t know that amount so X will stand for the amount of shirts sold than 7.50 times X = Y and Y = the amount earned
Answer:
(1, 0), (2, 0), and (-3, 0)
Step-by-step explanation:
The x intercepts are where it crosses the x axis. It crosses at (-3,0), (1,0) and (2,0)
Answer:
(3, - 25 )
Step-by-step explanation:
Given a quadratic in standard form : y = ax² + bx + c : a ≠ 0
The the x- coordinate of the turning point is
x = - 
Given
y = (x + 2)(x - 8) ← expand factors using FOIL
= x² - 6x - 16 ← in standard form
with a = 1 and b = - 6, thus
x = -
= 3
Substitute x = 3 into the equation for corresponding value of y
y = (3 + 2)(3 - 8) = 5(- 5) = - 25
turning point at (3, - 25 )
