Step-by-step explanation:

(5x-20) and (3x+8) will be equal since they are Vertically Opposite Angles

5x - 20 = 3x + 8

5x - 3x = 8 + 20

2x = 28

x = 28/2 = 14

now, (5x - 20) and (5x+ 4y) will sum up to 180 degrees because they form a linear pair.

so,

5x - 20 + 5x + 4y = 180 degrees

(5*14) - 20 + (5*14) + 4y = 180

70 - 20 + 70 + 4y = 180

140 - 20 + 4y = 180

120 + 4y = 180

4y = 180 - 120

4y = 60

y = 60/4

y = 15

the value of x=14 and value of y=15

What is the relationship between the base of an exponential function and its rate of growth?

S_A_V [24]

Answer:

growth rate is the number of times the base repeats

Step-by-step explanation:

We have that the general form of the exponential function is of the type:

f (x) = a ^ x

where "a" is the base and "x" is the exponent.

Therefore, the relation they keep to this exponent would be the growth rate since it is the number of times that the base is repeated, which means that the higher "x" is, the more times "a" is repeated.

Answer:

$\frac{6}{5}$

Step-by-step explanation:

given

perimeter = 2(l + w)

substitute the values for l and w into the formula and evaluate

=2( $\frac{2}{5}$ + $\frac{1}{5}$ )

= 2 × $\frac{3}{5}$ = $\frac{6}{5}$

A parabola has a focus of F(8.5,−4) and a directrix of x=9.5.

HACTEHA [7]

Answer:

$-\frac{1}{2}y^2-4y+1=x$

Step-by-step explanation:

A parabola has a focus of F(8.5,−4) and a directrix of x=9.5.

General form of horizontal parabola is

$(y-k)^2=4p(x-h)$

the distance between directrix and focus is the value of p

so p = 8.5 - 9.5 = -0.5

Focus is (h+p , k), given focus is (8.5, -4)

So k = -4 and h+p = 8.5

we know p = -0.5

h +p = 8.5

h - 0.5 = 8.5

so h= 9 and k = -4

vertex is (h,k) that is (9, -4)

Now plug in the value in the general equation

$(y-k)^2=4p(x-h)$ , k= -4, h= 9 , p = -0.5

$(y+4)^2=4(-0.5)(x-9)$

$(y+4)^2=-2(x-9)$

$y^2+8y+16=-2x+18$

subtract 18 on both sides

$y^2+8y-2=-2x$

Divide whole equation by -2

$-\frac{1}{2}y^2-4y+1=x$
