Set x to 0 to find the y value or set y to 0 to find the x value
Given equation, y = – 1.3(x + 3)2 – 9 is in slope intercept form.
Step-by-step explanation:
Slope intercept form standard formula:
y = mx + c
where,
y= y intercept
x= x intercept
m = slope
c = constant
We are given:
y = - 1.3(x + 3)2 - 9
y = - 2.6x + 7.8 - 9
y = -2.6x -1.2
So,
Slope = m = -2.6
constant = 1.2
Answer:
A
Step-by-step explanation:
pi*r²=616
22×r²=616×7
r²=4312/22
r=14
now
2piR=2×22/7×14
=88
Answer:
Step-by-step explanation:
tan55=8.9/x
x=8.9/tan55
x=6.2cm
Subtract 7 to 28 = 21 then divided by -3 = x= -7
