Answer:

x=8

Step-by-step explanation:

x+2=10

Put two on the other side, right next to 10. Change the addition sign to subtraction sign. And then, it turns into, x=10-2.

Solve that and then you get x=8.

Answer:

The degree of the power function is 3

Step-by-step explanation:

Let the power function be f(x) = b × xᵃ

Therefore, from the table, we have;

40 = b × (-2)ᵃ

5 =  b × (-1)ᵃ

0 = b × 0ᵃ

-5 = b × (1)ᵃ

-40 = b × (2)ᵃ

From -5 = b × (1)ᵃ, we have;

1ᵃ = 1, which gives;

-5 = b × 1

b = -5

From -40 = b × (2)ᵃ, where b = -5, we have;

-40 = -5 × (2)ᵃ

(2)ᵃ = -40/(-5) = 8

(2)ᵃ = 8 = (2)³

∴ a = 3

㏑(2)ᵃ = ㏑(8)

a·㏑(2) = ㏑(8)

a = ㏑(8)/(㏑(2)) = 3

a = 3

The power function is f(x) = -5 × x³

∴ The degree of the power function is 3.

Answer:

The correct answer is 109°

hope this helps

Answer:

109 degrees

Step-by-step explanation:

As we know all angles in a triangle adds up to 180 degrees.

Therefore 48+23=71

180-71= 109 degrees

Explanation:

The closer r gets to +1 or -1, the stronger the linear relationship will be.

If r is really close to +1, then we have a strong positive linear relationship. If r is close to -1, then we have a strong negative linear relationship.

Of the four choices given, we see that r = -0.94 is the closest to either endpoint mentioned. The next closest is r = 0.91

Put another way, we're looking for the r value that is furthest way from 0, but also that makes the inequality [tex]-1 \le r \le 1[/tex] true. Choice A fits that description best.

Answer:

The correct option is;

A. B'(-3, -3), C'(-1, 4), D'(2, 0)

Step-by-step explanation:

The given coordinates of the vertices triangle ΔBCD, are;

B(-3, 3), C(4, 1), D(0, -2)

The transformation to be performed is r(90°, 0) (ΔBCD) which is a 90 degrees counterclockwise rotation about the origin

The rule for transformation of a geometric figure by rotation of 90 degrees counterclockwise is given as follows;

The coordinates of the preimage (x, y), the coordinates of the image  (-y, x)

Therefore, we have;

The preimage B(-3, 3), the coordinates of the image after 90 degrees counterclockwise rotation is B'(-3, -3)

Similarly, we have;

The preimage C(4, 1), the coordinates of the image after 90 degrees counterclockwise rotation is C'(-1, 4)

For the point D, we have;

The preimage D(0, -2), the coordinates of the image after 90 degrees counterclockwise rotation is D'(2, 0)

Therefore, the correct option is B'(-3, -3), C'(-1, 4), D'(2, 0).

Answer:

The answer is D. 2e + 3f + 8

Step-by-step explanation:

4e + 6 -2e + 5f + 2 - 2f     1. We combine like terms

4e -2e + 6 + 2 + 5f - 2f

2e + 8 + 3f   OR     2e + 3f + 8

Answer:

y = x/4

Step-by-step explanation:

Use point (4, 1).

y = kx

1 = k * 4

k = 1/4

y = 1/4 x

y = x/4

Answer:

Perimeter - 24 m

Area - 27 m^2

Step-by-step explanation:

The perimeter of a shape can be solved by 2(length) + 2(width)

The length is 3 and the width is 9 so we can use those numbers instead

2(3) + 2(9) = 6 + 18 = 24 m = perimeter

To solve the area you have to multiply the length by the width.

The length is 3 and the width is 9 so we multiply those together

3*9 = 27 m^2

To solve for G(f(4))

First replace x with 4 in the equation of f(x), use the solution to replace x in g(x).

F(x) = -4x + 10

= -4(4) + 10

= -16 + 10

= -6

Now replace x in the equation of g(x) with -6

G(x) = x^2 + 7x + 5

= (-6)^2 + 7(-6) + 5

= 36 -42 + 5

= -1

The answer is -1

Answer:

2

Step-by-step explanation:

f(x)= -2x-6

we want to find f(-4).

So we substitute x for -4.

f(-4) = -2(-4)-6

      = 8-6

      =2

Therefore you f(-4) = 2

Can you provide a picture please?

Step-by-step explanation:

Answer:

y=-3x+9

Step-by-step explanation:

The lines are parallel, so they must have the same slope, and a different y-intercept. They must have the same slope so they never intersect, and a different y-intercept so that one is not directly on top of the other.

[tex]y-y_{1} =m(x-x_{1} )\\y-3=-3(x-2)\\y-3=-3x+6\\y=-3x+9[/tex]
