Answer:
29
Step-by-step explanation:
This is because this is a complementary angle so it equals 90 degrees. If you already have 61 degrees then you subtract 90 and 61 to get f=29 degrees
A parabola is a quadratic function, and a quadratic can be expressed in vertex form, which is:
y=a(x-h)^2+k, where (h,k) is the vertex (absolute maximum or minimum point of the quadratic)
In this case we are given that (h,k) is (-5,80) so we have so far:
y=a(x--5)^2+80
y=a(x+5)^2+80, we are also told that it passes through the point (0,-45) so:
-45=a(0+5)^2+80
-45=25a+80 subtract 80 from both sides
-125=25a divide both sides by 25
-5=a, so now we know the complete vertex form is:
y=-5(x+5)^2+80
The x-intercepts occur when y=0 so:
0=-5(x+5)^2+80 add 5(x+5)^2 to both sides
5(x+5)^2=80 divide both sides by 5
(x+5)^2=16 take the square root of both sides
x+5=±√16 which is
x+5=±4 subtract 5 from both sides
x=-5±4 so the x-intercepts are:
x=-1 and -9
Answer:
X= 25, the second one is 22, the third one is 19
y=20, the second one is 17, the thirst one is 12
The terms in patten y is 5 less than the terms in pattern x

Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
y + 6 = 
(x - 9) ← distribute the parenthesis
y + 6 = x - 3 ← subtract 6 from both sides
y = x - 9 ← in slope- intercept form
