Function operations and composition<br><br> g(a)= 4a +4<br> h(a)= -4a + 5<br> Find (g + h)(a)
poizon [28]

Answer:

(g + h)(a) = 9

Step-by-step explanation:

g(a)= 4a +4

h(a)= -4a + 5

(g + h)(a)

We add the functions

(g + h)(a) =  4a +4 + -4a + 5

Combine like terms

(g + h)(a) =0a +9

(g + h)(a) = 9

I need help please <br> Write an equation in slope intercept form for the following graph.
olganol [36]

Answer:

  • y = - 0.5x + 3

Step-by-step explanation:

<u>Take two points on the line:</u>

  • (0, 3) and (2, 2)

<u>The slope-intercept form:</u>

  • y = mx + b, where m- slope, b- y-intercept

<u>Find the slope:</u>

  • m = (2 - 3) / (2 - 0) = - 1 / 2 = - 0.5

The y- intercept is b = 3 according to the first point.

<u>The line is:</u>

  • y = - 0.5x + 3

What is the value of h in the figure below? In this diagram BAD~CBD
liberstina [14]

Answer:

The correct option is E. 8

The value of h is 8 unit.

Step-by-step explanation:

Given:

Δ BAD ~ Δ CBD

AC = 20

DC = 4

∴ AD = AC - DC=20-4=16

To Find:

h = ?

Solution:

Δ BAD ~ Δ CBD      ................Given

If two triangles are similar then their sides are in proportion.

\frac{BD}{CD} =\frac{AD}{BD} =\frac{BA}{CB}\ \textrm{corresponding sides of similar triangles are in proportion}\\  

On substituting the given values we get

\dfrac{BD}{CD} =\dfrac{AD}{BD}

\dfrac{h}{4} =\dfrac{16}{h}\\\therefore h^{2}=64\\\therefore h=8\ unit

The value of h is 8 unit.
