Answer:

A: The x-intercept of k(x) is half the x-intercept of h(x)

Step-by-step explanation:

Answer choices B, C, and D are concerned with slopes and y-intercepts. The coefficients of x in the functions are different and are related by a factor of -2, so the lines are not parallel, and one slope is not twice the other. The y-intercepts (constants) in each function are different, so they graphs do not cross the y-axis at the same place.

Hence answer choices B, C, and D can be eliminated.

The x-intercepts are found by setting y=0 and solving for x:

h(x) = 0 = -2x +4 ⇒ x = 4/2 = 2

k(x) = 0 = 4x -4 ⇒ x = 4/4 = 1

The x-intercept of k(x) is half that of h(x). . . . . . . matches choice A

$\\ \\ n=\frac { 5 }{ 6 } \left( 20+4 \right) \\ \\ n=\frac { 100 }{ 6 } +\frac { 20 }{ 6 } \\ \\ n=\frac { 120 }{ 6 } \\ \\ n=20$

Which system of inequalities is shown?

anzhelika [568]

Answer:

Option C

Step-by-step explanation:

from the graph: y<4

so option A and B are wrong.

also if we choose any points in the area, always x will be bigger than y. so x>y

First picture is by itself. Next is graph problem :)

Answer:

1). g(-9) = -81.914

2). Last option

Step-by-step explanation:

1). f(x) = x²

For x = -9

f(-9) = (-9)² = 81

g(x) = $\frac{32}{2x-17}$

g(-9) = $\frac{32}{[2(-9)-17]}$

= $\frac{32}{-35}$

= - $\frac{32}{35}$

(g - f)(-9) = g(-9) - f(-9)

= $-\frac{32}{35}-81$

= $\frac{-32-2835}{35}$

= $-\frac{2867}{35}$

= -81.914

2). The relation is not a function because this function doesn't passes a vertical line test.

Last option will be the answer.

Is the histogram uniform, symmetric, or skewed?

hodyreva [135]

A histogram is a graph used to present ranges of data. In contrast to bar graphs or vertical graphs, these are more used in displaying complex and higher statistical data ranges. Moreover, the illustration is Uniform. Uniform in that it portrays that the data is in a rectangular shaped form.

Step by step workout of ;<br> log x^3+log 5x=5 log 2-log 2/5

Charra [1.4K]

Answer:

x = 2

Step-by-step explanation:

$log \: {x}^{3} + log \: 5x = 5log \: 2 - log \: \frac{2}{5} \\ \\ \therefore \: log( {x}^{3} \times 5x) = log {2}^{5} - log \: \frac{2}{5} \\ \\ \therefore \: log( 5{x}^{4}) = log 32 - log \: \frac{2}{5} \\ \\ \therefore \: log( 5{x}^{4}) = log \bigg(32 \times \frac{5}{2} \bigg) \\ \\ \therefore \: log( 5{x}^{4}) = log \bigg(16 \times 5) \\ \\ \therefore \: 5{x}^{4}= 16 \times 5 \\ \\ \therefore \: {x}^{4}= {2}^{4} \\ \\ \huge \purple{ \boxed{\therefore \: {x} = 2}}$
