Answer:

- 18.4

Step-by-step explanation:

The given expresion is

- 9.2(4 - x)

We want to evaluate this expression for x=2.

We substitute x=2 into the expression.

This means that, we will put 2 wherever we see x in the given expresion.

This will give us:

- 9.2(4 - 2)

Simplify the parenthesis

- 9.2(2)

=  - 18.4

Help please, what’s: 5x-7+2-2x=-26
svetoff [14.1K]

Answer:

7

Let's solve your equation step-by-step.

5x−7+2−2x=−26

Step 1: Simplify both sides of the equation.

5x−7+2−2x=−26

5x+−7+2+−2x=−26

(5x+−2x)+(−7+2)=−26(Combine Like Terms)

3x+−5=−26

3x−5=−26

Step 2: Add 5 to both sides.

3x−5+5=−26+5

3x=−21

Step 3: Divide both sides by 3.

3x

3

=

−21

Brenda collected this data from an experiment.
Gelneren [198K]

Answer:

7.04

Step-by-step explanation:

To get the value of residual of the data point, we simply substitute 11 for t

The substitution equation is h = 0.6t + 0.44

Substituting 11, we have

h = 0.6(11) + 0.44

h = 6.6 + 0.44

h = 7.04

The graph shows the altitude, a, of a plane, in feet, after t minutes. What is the rate of ascent of the airplane?
alexira [117]

The rate of ascent is also known as the slope. To find the slope, we will follow the steps below.

Step 1) Choose two points on the line

Point 1: (4, 500)

Point 2: (8, 1000)

Step 2) Use the slope formula to find the slope

m = (y2 - y1) / (x2 - x1)

m = (1000 - 500) / (8 - 4)

m = 500 / 4

m = 125 feet per minute

Hope this helps! :)
