Answer:
y=10
Step-by-step explanation:
Answer:
15 degrees, 75 degrees
Step-by-step explanation:
Call the first angle's measurement m
∠
1
.
The second angle is 5 times this, or 5
(
m
∠
1
)
.
Since the two angles are complementary (have a sum of 90
˚
), we can relate the two angles him as follows:
m
∠
1
+
5
(
m
∠
1
)
=
90
6
(
m
∠
1
)
=
90
m
∠
1
=
15
Since m
∠
2
is 5
times this, m
∠
2
=
15
×
5
=
75
.

Answer: The graph of linear inequalities include a dashed line if they are greater than or less than but not equal to. Linear equations, on the other hand, include a solid line in every situation. Moreover, linear inequalities include shaded regions whereas linear equations do not.

Answer:
Step-by-step explanation:
f(x)=4/5x^2+12x
For f(5)
: f(x) = 4/5(5)2 + 12(5)
= 4/5 × 25 + 60
= (4×5) + 60
= 20 + 60
= 80
Answer:
f(x) = -5x +48
Step-by-step explanation:
A fairly easy way to write the equation of the perpendicular line is to swap the x- and y-coefficients, negating one of them. Then choose the constant in the equation to make it true at the given point.
<h3>Swapped coefficients</h3>
In this instance, we find it convenient to leave the coefficient of y as positive.
5y = x -10 . . . . . . original equation
y = -5x +c . . . . . . with coefficients swapped, x-coefficient negated
<h3>New constant</h3>
At the given point, the equation becomes ...
8 = -5(8) +c
48 = c . . . . . . . add 40
<h3>Equation of the perpendicular line</h3>
The equation of the line is then ...
y = -5x +48
f(x) = -5x +48 . . . . . . in functional notation
