Answer:

Step-by-step explanation:

A(1,7); B(-3,-1); slope m =(-1-7)/-3-1) = -8/-4 = 2

Equation of a line AB is

((y-y1) = m(x-x1)

y - 7 = 2(x-1)

y - 7 = 2x-2

y = 2x + 5

Answer:

y = 2x +5

Step-by-step explanation:

Equation of a line

The point-slope form of the equation of a line is:

y - k = m ( x - h )

Where m is the slope and (h,k) is a point through which the line passes.

Suppose we know the line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:

[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]

The image provides two points A(1,7) and B(-3,-1), thus the slope is:

[tex]\displaystyle m=\frac{-1-7}{-3-1}[/tex]

[tex]\displaystyle m=\frac{-8}{-4}[/tex]

m = 2

Now we apply the point-slope form taking the point (1,7):

y - 7 = 2 ( x - 1 )

Operating:

y - 7 = 2x - 2

Adding 7:

y = 2x +5

The line of reflection is the vertical line x = 1.

A reflection is a type of transformation that involves flipping a shape, known as the preimage, over a line, known as the line of reflection, to produce a new shape (called the image). You can picture what would happen if you flipped the form over the line in order to graph a reflection.

The line of reflection is the vertical line passing through the midpoint of segment AA'.

Since A'(2,5) and A(-4,5) have the same y-coordinate, their midpoint is on the line y = 5.

Therefore, the line of reflection is the vertical line x = 1.

Answer:

x equals 51

Step-by-step explanation:

1. Do the inverse operation of x/-3 which is multipulcation.

2. Multiply -17 by -3 to get the answer of 51.

Finish the equation by saying that x = 51, or 51 = x.

Answer:

X=51

Step-by-step explanation:

You would have to multiply 17 by 3.

10x3=30

7x3=21

then you add 30 and 21 which equals 51

Answer:  Choice C.  [tex]x \ge -3[/tex]

============================================

Explanation:

The domain is the set of all allowed x inputs.

Here we see that x = -3 is the smallest x value possible as it is from the left-most point. The graph goes on forever to the right, so there is no largest x value. Effectively infinity is the largest x value even though infinity is not a number.

We can say the domain is [tex]-3 \le x < \infty[/tex] which can be simplified to [tex]-3 \le x[/tex] or [tex]x \ge -3[/tex]

In short: x can be -3 or larger.

Answer:

Step-by-step explanation:

First we find the GCF or Greatest Common Factor

20: 1, 2, 4, 5, 10, 20

16: 1, 2, 4, 8, 16

As you can see 4 is the GCF (Greatest Common Factor)

so, the largest number of groups are 4

Unless you are asking for how many girls and boys can be fit in each group then,

20 ÷ 4 = 5

16 ÷ 4 = 4

So, 5 boys and 4 girls are in each group.

Answer:

y = - [tex]\frac{1}{10}[/tex] x + 3

Step-by-step explanation:

x + 10y = 30 ( subtract x from both sides )

10y = - x + 30 ( divide all terms by 10 )

y = - [tex]\frac{1}{10}[/tex] x + 3

x = 2

Step-by-step explanation:

Given

- 2 (1 - 4x) = 3x + 8 ( distribute parenthesis on left side )

- 2 + 8x = 3x + 8 ( subtract 3x from both sides )

- 2 + 5x = 8 ( add 2 to both sides )

5x = 10 ( divide both sides by 5 )

x = 2

The amount of Shortening = 3/2

The amount of Salt = 2/2 = 1

The amount of Granulated Sugar = 9/2

The amount of Baking Soda = 6/2 = 3

The amount of Beaten Eggs = 1/2

The amount of Vanilla Extract = 1

The amount of Cake Flour = 4

What is Multiplication?

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

For, 3 Dozen cookies we use;

The amount of Shortening = 3/4

The amount of Salt = 1/2

The amount of Granulated Sugar = 9/4

The amount of Beaten Eggs = 1/4

The amount of Vanilla Extract = 1/2

The amount of Butter Flavoring = 1/4

The amount of Baking Soda = 3/2

The amount of Cake Flour = 2

The amount of Food Coloring = 1/2

Since, We have to calculate all amount of things for 6 dozen cookies.

And, 3 x 2 = 6

Hence, 6 Dozen cookies make with;

The amount of Shortening = 3/4 x 2 = 3/2

The amount of Granulated Sugar = 9/4 x 2 = 9/2

The amount of Beaten Eggs = 1/4 x 2 = 1/2

The amount of Vanilla Extract = 1/2 x 2 = 1

Answer:

1,436

Step-by-step explanation:

First multiply the growth rate by the number of hours.

3.25 x 5 = 16.25

Now multiply 1,235 by 100. = 123,500

And also multiply 1235 by the remainder percentage not being used(83.75)= 103,060.75

Now subtract 123,500 - 103,060.75 = 20,439.25

Divide this number by 100 = 204.3925 which is what 16.25% of 1,235 is.

1,235 + 204 = about 1,439 but since i rounded up a few times the answer is actually 1,435.6875 rounded up to 1,436
