Y = 25x + 35
She will have $160 after five weeks
x = - 6 and x = 7
given x² - x - 42 = 0 ← quadratic in standard form
(x - 7 )(x + 6) = 0 ← in factored form
equate each factor to zero and solve for x
x - 7 = 0 ⇒ x = 7
x + 6 = 0 ⇒ x = - 6
Phthagorean theorme is
a^2+b^2=c^2
where you have a right triangle and c =hypotonuse( normally the longest side, and opposite of right angle)
a and b are the legs
so we are given
one leg=8
hypotonues=10
subsitute
leg=a or b so just subsitute for one
subsitutt for b
a^2+8^2=10^2
expand
8^2=64
10^2=100
a^2+64=100
subtract 64 from both sides
a^2=36
square root both sides
a=6
answe ris 6 feet
If 3x>96, dividing both sides by 3 we get that x>32, therefore only E is an acceptable answer
