First one.....................
point slope form of a line
y-y1 = m(x-x1)
y-4 = -3(x--5)
y-4 =-3(x+5)
to change to slope intercept form
dstribute
y-4 = -3x-15
add 4 to each side
y = -3x-15+4
y = -3x-11
Answer:first choice
Step-by-step explanation:
25+12.50h<_ 100
<_ means he can spend exactly 100 or less because that's all he has
Subtract 25 on both sides
12.50h<_ 100-25
12.50h<_ 75
Divide by 12.50
h<_ 6
Answer:
we know that
By alternate interior angles
m∠PRD=m∠APR -------> equation
m∠PRD=120°
so
m∠APR=120°
m∠APR=m∠APQ+m∠QPR ---------> equation
m∠APQ=62°
m∠QPR=x°
Substitute the values in the equation 120=62+x
x=120-62
x=53
therefore
the answer is
The measure of angle x is equal to 53 degrees
The answer is A, y = (x+3)^2 -3
