Answer:

  B.  9x² +15x -6

Step-by-step explanation:

The composition operator means that function f is applied to function g:

  [tex](f\circ g)(x)=f(g(x))=f(3x-1)\\\\=(3x-1)^2+7(3x-1)\\\\=9x^2-6x+1+21x-7\\\\\boxed{(f\circ g)(x)=9x^2+15x-6}\qquad\textbf{matches B}[/tex]

Answer:x=20 y=70

Step-by-step explanation:

Answer:

x=20, y=70

Step-by-step explanation:

∠40°+∠adjacent to it =180°

∠adjacent= 180-40=140°

we see that 2 of the sides of one of the small triangles are congruent so that triangle is isoscel so the base angles are congruent as well

because sum of angles in a triangle has to be 180,

140 +x+x=180 so x=20°

from the right triange we see thhat y +90+20 =180 because sum of angle in a triangle has to be 180 so y=70

Answer:

The slope-intercept equation is:

[tex]y=\frac{3}{2}x+1[/tex]

Step-by-step explanation:

Given the equation

[tex]y-4=-\frac{2}{3}\left(x-6\right)[/tex]

comparing it with the point-slope form of the line equation

[tex]y-y_1=m\left(x-x_1\right)[/tex]

where m is the slope

As we know that the slope of the perpendicular line is basically the negative reciprocal of the slope of the line, so

The slope of the perpendicular line will be: 3/2

The point-slope form of the equation of the perpendicular line that goes through (-2, -2) is:

[tex]y-y_1=m\left(x-x_1\right)[/tex]

[tex]y-\left(-2\right)=\frac{3}{2}\left(x-\left(-2\right)\right)[/tex]

[tex]y+2=\frac{3}{2}\left(x+2\right)[/tex]

writing the line equation in the slope-intercept form

[tex]y+2=\frac{3}{2}\left(x+2\right)[/tex]

subtract 2 from both sides

[tex]y+2-2=\frac{3}{2}\left(x+2\right)-2[/tex]

[tex]y=\frac{3}{2}x+1[/tex]

Thus, the slope-intercept equation is:

[tex]y=\frac{3}{2}x+1[/tex]

Here,

As the slope-intercept form is

[tex]y=mx+b[/tex]

where m is the slope and b is the y-intercept

so

[tex]y=\frac{3}{2}x+1[/tex]

m=3/2

b = y-intercept = 1

Therefore, the slope-intercept equation is:

[tex]y=\frac{3}{2}x+1[/tex]

Step-by-step explanation:

Hey there!

We know that the slope intercept is; y = mx+b.

Where "m" represents the slope. And "b" represents the y-intercept.

Example:

If the question is as; y = 3x +8

Then your slope of the slope intercept form is "3" where as "8" is y-intercept.

So, the variable"m" represents the slope.

Answer: Fail to reject H0

Step-by-step explanation:

Given that:

P value = 0.26

α = 0.1

The values of both p and α can be compared in other to make a decision on whether to reject or fail to reject the Null hypothesis

Decisions :

If the p value > α (fail to reject null)

If p value < α ( Reject null)

In the scenario above :

0.26 > 0.1 ; p value > α

Since the p value is greater than alpha ; we fail to reject the Null

Answer:

x+3y=0

Step-by-step explanation:

The standard form of the given equation is y = -1/3 x +4.

The given equation is y-2 = -1/3(x + 6)

The slope intercept form of a straight line is one of the most common forms used to represent the equation of a line. The slope intercept formula can be used to find the equation of a line when given the slope of the straight line and the y-intercept.

The standard form of the slope intercept form is y=mx+c.

Here, the given equation can be rewritten as

y-2 = -1/3 x + 2

y = -1/3 x + 2+2

y = -1/3 x +4

Therefore, the standard form of the given equation is y = -1/3 x +4.

The correct answer is 82% of 50 (41) / 170% of 30 (51) /65% of 80 (52)

Explanation:

The first step to know whether a value is greater than another is to find the value each percentage represents depending on the total. This process is shown below.

1. 65% of 80- This implies 80 is 100% and 85% needs to be found. Use the following formula:

80 / 100 = 0.8 x 65 = 52 or the total number divided by 100 and multiplied by the percentage you want to know

2. 82% of 50 - Repeat the same process

50 / 100 = 0.5 x 82 = 41

3. 170% of 30

30 / 100 = 0.3 x 170 = 51

4. Finally organize the values

82% of 50 (41)

170% of 30 (51)

65% of 80 (52)

Based on the information given about the percentages ,the ordering will be 82% of 50, 170% of 30, and 65% of 80.

It should be noted that 82% of 50 will be:

= 82% × 50

= 41

170% of 30 will be:

= 1.7 × 30

= 51

65% of 80 will be:

= 65% × 80

= 0.65 × 80

= 52

Answer:

Option C

Step-by-step explanation:

Difference of the two expressions has been written as,

[tex]\frac{3x}{x^2-7x+10}-\frac{2x}{3(x-5)}[/tex]

To rewrite this expression as one expression,

First he factored the the denominators,

[tex]\frac{3x}{(x-2)(x-5)}-\frac{2x}{3(x-5)}[/tex]

Then Juan will make the denominators of both the terms equal,

For which he will multiply the second expression by [tex]\frac{x-2}{x-2}[/tex].

[tex]\frac{3x}{(x-2)(x-5)}-\frac{2x(x-2)}{3(x-5)(x-2)}[/tex]
