Can y’all plz help me

Answer:

The mistake he made was not distributing the 1/4 to all the terms in the parentheses. It should've instead become 1/4x + 3, which would then lead to a different answer

Answer:

He forgot to divide 12 by 4.

Step-by-step explanation:

1/4(x + 12) = 2

1/4(x) + 1/4(12) = 2

x/4 + 12/4 = 2

x/4 + 3 = 2

x/4 = -1

x = -1/4

Answer:

B. a square matrix

Step-by-step explanation:

Because diagonal matrix are those matrix having non zero elements only on diagonal and rest all are zero.

Square matrix are those having number of rows equal to number of columns.

Zero matrix is a matrix having all elements equals to zero.

Identity matrix are those matrix having one only on diagonal and rest all elements are zero.

Answer:

f(-6)=23

Step-by-step explanation:

f(-6)=23

Hope this helps you!!!!

For x/2 to be greater than or equal to 10, you must try out a few numbers.

If x = 20...

x/2 greater than or equal to 10

= 20/2 greater than or equal to 10

= 10 greater than or equal to 10.

So the answer for x is:

x = 20 or more

Hope this helps!!!

Answer:

two

Step-by-step explanation:

In the case when there is a congruent rectangle so that represent the equal sides i.e. the width and the length would be the same.

Since it is mentioned that one rectangle JKLM has 4 inch and 7 inches dimension so there would be the possibility that the length of J M might be 4 or 7

So here the possibility of the length is two

b: two

Answers:

Domain = {-24, -6, -4, 4, 21, 47}

Range = {24, 55, 45, 77, 3, 93}

Don't forget about the curly braces.

The domain is the set of all allowed x inputs. So we simply list all the x coordinates of the points given. That's all there is to it. The range is the list of all possible y output values, so we just list the y coordinates. Toss out any duplicate y values. Sorting each set is optional because order doesn't matter in a set.

Answer:

Pete: 39, Linda: 42

Step-by-step explanation:

Suppose Pete has x dollars. If he has 3 dollars less than Linda, then Linda has 3+x dollars. Together, they have 81 dollars:

x+3+x=81

2x+3=81

2x=78

x=39

Since Pete has x dollars, and x=39, he has $39.

Linda has 3+x, which is 39+3 = $42

I hope this helps! :)

Answer:

The length of the rectangle is given as:

(9x + 6)

Step-by-step explanation:

The area of a rectangle is given as:

Length × Width

Area of the rectangle = 45x² − 42x − 48

Width = 5x - 8

We solve for the length of the rectangle by factorising the area of the rectangle

45x² − 42x − 48

45x² - 72x + 30x - 48

(45x² - 72x )+ (30x - 48)

9x(5x - 8) + 6(5x - 8)

(5x - 8)(9x + 6)

Therefore:

The length of the rectangle is given as:

(9x + 6)

B. dividend
A. divisor

Step-by-step explanation:

cos(x)=31/47

x=cos^-1 (31/47)

Step-by-step explanation:

use the law of cosine for right triangles cos(θ)= adjacent/ hypotenuse

cos(θ)=31/47=.659

θ=inverse cosine of .659

θ=48.73

Answer:

-2/1

Step-by-step explanation:

Answer:

1) 4.2 inches

2) 63 inches²

Step-by-step explanation:

If the base is 15 inches, we can assume that the opposite side is also 15 inches. 15 + 15 = 30. If we subtract 30 from the total perimeter, we will have the sum of the last two sides.

38.4 - 30 = 8.4

Now that we have the sum we can now find the exact length with division:

8.4/2 = 4.2 inches

To find the area, we multiply these together.

4.2 * 15 = 63

Answer:

Step-by-step explanation:

Corresponding angles of both the squares are congruent. (angles of a square measure 90°)

Ratio of the sides of the given squares = [tex]\frac{\text{Side length of small square}}{\text{Side length of the large square}}[/tex]

                                                                 = [tex]\frac{2}{5}[/tex]

This ratio of side lengths is constant for all corresponding sides.

Therefore, corresponding sides are proportional.

Since, all angles of both the squares are congruent and all the sides are proportional, both the squares will be similar.

Scale factor = [tex]\frac{\text{Side length of large square}}{\text{Side length of the smaller square}}[/tex]

                    = [tex]\frac{5}{2}[/tex]

                    = 2.5

This sequence of similarity transformations shows the figures are similar.

Emilia = 2 cups of grape juice for every 5 cups of pineapple juice

We can simplify this to 1 cup of grape juice for every 2 1/2 cups of pineapple juice

Darnell = 1 cup of grape juice for every 4 cups of pineapple juice

You can see the difference

Answer:

(6, - 9 )

Step-by-step explanation:

Given the 2 equations

6x + 2y = 18 → (1)

- 4x - 2y = - 6 → (2)

Adding the 2 equations term by term will eliminate the y- term, that is

2x + 0 = 12

2x = 12 ( divide both sides by 2 )

x = 6

Substitute x = 6 into either of the 2 equationsand solve for y

Substituting into (1)

6(6) + 2y = 18

36 + 2y = 18 ( subtract 36 from both sides )

2y = - 18 ( divide both sides by 2 )

y = - 9

solution is (6, - 9 )
