Answer:

The value of the expression is 382

Step-by-step explanation:

x = 77 and the expression given is 5x - 3

5x - 3

input the given

5(77) - 3

solve

5 times 77 is 385

so now we have

385 - 3 which equals 382

so our final answer is 382

A line contains the points (-26, -37) and (32, -61)
Slav-nsk [51]

The slope of line through given points is -12/29

Step-by-step explanation:

Given points are:

(-26, -37) and (32, -61)

Let

(x1,y1) =(-26, -37)

And

(x2,y2) = (32, -61)

Slope (steepness) of a line, denoted by m, is given by the formula

m = \frac{y_2-y_1}{x_2-x_1}

Putting the values

m = \frac{-61-(-37)}{32-(-26)}\\\\=\frac{-61+37}{32+26}\\\\=\frac{-24}{58}\\\\=-\frac{12}{29}

Hence,

The slope of line through given points is -12/29

Keywords: Slope, line segment

Find the total surface area of rectangular prism with l=6, w=4, h=2
natali 33 [55]

SA = (l x w x 2) + (l x h x 2) + (w x h x 2)

SA = (6 x 4 x 2) + (6 x 2 x 2) + (4 x 2 x 2)

SA = 48 + 24 + 16

SA = 88

The answer is 88 square units.

Identify the exponent in the term –3x2. A. x B. 2 C. minus sign (–) D. 3
Vedmedyk [2.9K]

Answer:

B. 2

Step-by-step explanation:

Assuming the term is meant to look like this: -3x², then the answer is B.2. An exponent is a superscript (super means above, script means writing) that tells you to multiply something by itself.

In this case, -3x² means -3·x·x

If it was written as (-3x)², it would mean (-3x)·(-3x)
