Answer:

Seven.

Step-by-step explanation:

-3-(-8)-(-2)

Using PEMDAS, we are working with only subtraction, which means we will be moving from the left to the right.

Let's start with -3-(-8)

At first it seems like -3-8, which would be -11, HOWEVER, this is incorrect, because it is -8, not 8.

When subtracting a negative number, like we are doing in this problem, it actually turns into addition.

Therefore, -3-(-8) becomes -3+8, which is 5.

After doing this, we have 5-(-2).

Again, we are subtracting a negative number, so in actuality you want to add it.

So instead of 5-(-2), we are actually doing 5+2, which is 7.

Therefore -3-(-8)-(-2) is 7.

The equation of the line in this graph is<br>y= ____ x+____ .<br>

Alexxx [7]

The equation of the line in this graph is y = 3/2x + 3.

Explanation:

In slope intercept form equations, the initial value is where everything begins. In this equation, that would be at the point (0,3). From there, because it is going up toward the right side, there is a positive slope. The formula for slope is rise over run, so to get our slope, we have to go up 3 units and over 2 units.

4. Determine the circumference of a circle with a radius that is 14.2 yds. Use 3.14 for π. Round to the nearest tenth.

Vladimir79 [104]

Answer:

The circumference would be around 90 yards.

Step-by-step explanation:

C = 2πr

r = 14.2

14.2 × 3.14 = 44.588

44.588 × 2 = 89.176

89.176 ≈ 90

C = 90

What is the solution to the following equation? (4 points) 2(3x − 7) + 18 = 10

konstantin123 [22]

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

2*(3*x-7)+18-(10)=0

Step by step solution :

Step 1 :

Equation at the end of step 1 :

(2 • (3x - 7) + 18) - 10 = 0

Step 2 :

Step 3 :

Pulling out like terms :

3.1 Pull out like factors :

6x - 6 = 6 • (x - 1)

Equation at the end of step 3 :

6 • (x - 1) = 0

Step 4 :

Equations which are never true :

4.1 Solve : 6 = 0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation :

4.2 Solve : x-1 = 0

Add 1 to both sides of the equation :

x = 1

One solution was found :

x = 1
