Amber and her friend Nathan are
Gnesinka [82]

Answer:

{(12-4) + (15-8)}x  = 65

Step-by-step explanation:

The amount Amber earns per week

12-4

The amount Nathan earns per week

15 -8

The total amount per week they earn together

(12-4) + (15-8)

Multiply by x weeks

{(12-4) + (15-8)}x

Set this equal to 65 to be the amount they need to equal 65 dollars

{(12-4) + (15-8)}x  = 65

The speed of a runner increased steadily during the first two seconds of a race. Col1 Time (Sec) 0 0.5 1 1.5 2 Col2 Speed (ft/se
UkoKoshka [18]

Answer:

The distance is D. 21.25 ft.

Step-by-step explanation:

This is an example of a distance problem: <em>Find the distance traveled by an object during certain time period if the velocity of the object is known at all times.</em>

We are given a table of values for time and speed

\left\begin{array}{cccccc}t(sec)&0&0.5&1&1.5&2\\Speed (ft/sec)&0&5.1&9.3&12.5&15.6\end{array}\right

If the speed remains constant, then the distance problem is easy to solve by means of the formula

                                          distance = speed x time

Therefore, the total distance is

distance = 5.1\cdot 0.5+9.3\cdot 0.5+12.5\cdot 0.5+15.6\cdot 0.5\\distance = 21.25 \:ft

slega [8]

Answer:

-3

3/2

Step-by-step explanation:

Y intercep is the point where the line intercepts the y axis. That is 3 in this graph.

slope. Choose two points. For the sake of explainin, I am choosing

(-3,1)

and (0,3). That’s the y intercept!!

The slope is the rate of increase. We have to measure it like we do with stairs. The rise divided by the run

the rise is 2. See the picture. The run is 3(change in x) the x increases by 3 between 2 integer points while the y changes by 3(change in y —>3 minus 1)

Rise= 3

run =2

Slope=rise/run=3/2

How do you solve equations with two variables
liubo4ka [24]

Answer:

Step-by-step explanation:

To solve systems of algebraic equations containing two variables, start by moving the variables to different sides of the equation. Then, divide both sides of the equation by one of the variables to solve for that variable. Next, take that number and plug it into the formula to solve for the other variable.
