Anastasy [175]3 years ago

Answer:

Attention! the "x" variable was missing in your typed question, but I am assuming that the actual function was defined by: y=-\frac{2}{3} x+7

Table:

\left[\begin{array}{cc}x & y\\-12&15\\-6&11\\3&5\\15&-3\end{array}\right]

Step-by-step explanation:

In order to complete the requested table, we need to evaluate "y" for the four given values of the "x" variable in the Domain: {-12. -6, 3, 15}

Evaluation:

y=-\frac{2}{3} x+7\\y=-\frac{2}{3} (-12)+7=8+7=15

y=-\frac{2}{3} x+7\\y=-\frac{2}{3} (-6)+7=4+7=11

y=-\frac{2}{3} x+7\\y=-\frac{2}{3} (3)+7=-2+7=5

y=-\frac{2}{3} x+7\\y=-\frac{2}{3} (15)+7=-10+7=-3

The table therefore will be:

\left[\begin{array}{cc}x & y\\-12&15\\-6&11\\3&5\\15&-3\end{array}\right]

PLEASE HELP ASAP 30 POINTS ):

Answer:

c (0,-4)

Step-by-step explanation:

-5x+y = -4

4x - 4y =16

Solve the first equation for y since we are using substitution.

-5x+y = -4

Add 5x to each side

-5x+5x+y = -4+5x

y = 5x-4

Substitute this equation y = 5x-4 into the second equation.

4x -4(5x-4) = 16

Distribute the -4

4x - 4(5x) -4(-4) = 16

4x-20x +16 = 16

Combine like terms

-16x +16 =16

Subtract 16 from each side

-16x+16-16 = 16-16

-16x =0

Divide by -16

x=0


But we still need to find y

y = 5x-4

y = 5(0) -4

y = -4

7m-6; m =8<br><br> What’s the answer!??
boyakko [2]

Answer:

m = 8 Please brainliest!

Step-by-step explanation:

Simplifying

7m + -6m = 8

Combine like terms: 7m + -6m = 1m

1m = 8

Solving

1m = 8

Solving for variable 'm'.

Move all terms containing m to the left, all other terms to the right.

Divide each side by '1'.

m = 8

Simplifying

m = 8

Using the quadratic equation formula to solve 7x^2-x=7, what are the values of x
Gennadij [26K]

quadratic formula:

x = <u>-b ± √(b² - 4ac)</u>

             2a

7x² - x = 7

subtract 7 from both sides:

7x² - x - 7 = 0

plug values into the quadratic formula:

x = <u>-(-1) ± √((-1)²- 4(7)(-7))</u>

               2(7)

simplify:

x = <u>1 ± √(197)</u>

           14

If $396 is invested at an interest rate of 13% per year and is compounded continuously, how much will the investment be worth in
Vilka [71]

Answer:  First option is correct.

Step-by-step explanation:

Since we have given that

Amount invested = $396

Interest rate = 13% per year

Time = 3 years

We will use the "Exponential growth formula" i.e.

A=Pe^{rt}

Here,

P denotes Principle amount

r denoted rate of growth

t  denotes number of years,

So, it becomes

A=396e^{0.13\times 3}\\\\A=396e^{0.69}\\\\A=\$584.88

Hence, First option is correct.
