FromTheMoon [43]

Answer:

see the explanation

Step-by-step explanation:

Let

D -----> Danielle's age

C -----> Counselor's age

we know that

$C=3D$ ----> equation A

$D+C=28$ ----> equation B

substitute

equation A in equation B

$D+3D=28$ ----> equation that can be used to find Danielle's age

Solve for D

$4D=28$

$D=7$

<em>Find the value of C</em>

$C=3D$ ----> equation that can be used to find Counselor's age

substitute the value of D

$C=3(7)=21$

therefore

Danielle's age is 7 and Counselor's age is 21

Find the x - and y - intercepts of the line. X + 3y=6Y intercept: ( , )X intercept: ( , )

pantera1 [17]

ANSWER:

Y intercept: (0, 2)

X intercept: (6, 0)

STEP-BY-STEP EXPLANATION:

We have the following equation:

$x+3y=6$

The x-intercept is when y is equal to 0 and the y-intercept is when x is equal to 0, therefore:

$\begin{gathered} \text{ x-intercept } \\ x+3\cdot0=6 \\ x=6\rightarrow(6,0) \\ \text{ y-intercept } \\ 0+3\cdot y=6 \\ y=\frac{6}{3}=2\rightarrow(0,2) \end{gathered}$

Write the following linear equation in function notation y=7x-2

BARSIC [14]

Answer:

The function notation is when we represent one of the coordinate points as a function of the other ones.

In the general case, we will have:

y = f(x)

Now, we have that:

y = 7*x - 2

Then the function notation will be:

y = f(x) = 7*x - 2

or simply

f(x) = 7*x - 2
