Which of the following best describes the expression 3x + 2y + 8z?

The product of three sums; there are three terms

The sum of three products; there are three terms

The product of three sums; there are six terms

The sum of three products; there are six terms.

As you can see from the options, there is only one that is correct, since the terms are adding up, each term is 3x, 2y, and 8z, these are the three terms that we can find in the expression, and since they are products of a multiplication, they are the sum of three products, and there are only three terms, remember that the word product in math means the result of a multiplication, since 3 is multiplying x 2 is multiplying y and 8 is multiplying z we have three multiplications, or 3 products, and we are adding them up, so the correct option would be The sum of three products; there are three terms.

A triangle has the coordinates

fiasKO [112]

Answer:

coordinates of its image

A' = ( -4, -1)

B' =( -3, -3)

C' = ( 0, 2)

Step-by-step explanation:

Reflect in y-axis means mirror it's points in the y -axis.

This means that the x coordinate of each point, changes only. Any mirrored point in the y-axis, will change only, by multiplying the x-coordinate by -1.

(Remember, zero multiplied by -1 remains 0).

Given are these points A, B, and C.

A = (4, -1)

B = (3,-3)

C = (0, 2)

After mirroring in the y- axis you get:

A' = ( -4, -1)

B' =( -3, -3)

C' = ( 0, 2)

Help me & I'll help you in return??Need expert answer

Alenkasestr [34]

Answer:

(y-24)=-7(x+4)

Step-by-step explanation:

To write the equation of a line we must have a slope and a point. To find the slope we use the slope formula and substitute (x,y) points in it as shown below:

$m=\frac{y_2-y_1}{x_2-x_1}=\frac{24--53}{-4-7}=\frac{24+53}{-4+-7}=\frac{77}{-11}=\frac{-7}{1}=-7$

Now that we have the slope, plug in the slope and choose one point to plug into the point slope formula. Use the point-slope form to write the equation, then simplify and convert into the slope intercept form.

(y-24)=-7(x--4)

(y-24)=-7(x+4)
