Answer:

<u>Y</u><u>=</u><u>5</u>

Step-by-step explanation:

Heres the equation

-7(y-3)=-14

Let's distribute first

-7y+21=-14

Subtract 21 from each side

-7y= -35

/-7 /-7

<u>y</u><u>=</u><u>5</u>

Answer:

\large\boxed{\text{y\,=}\,5}

Step-by-step explanation:

In this question, we're solving for y, meaning that we will solve the equation in order to figure what what y = ?

Solve:

-7(y-3)=-14\\\\\text{We would use the distributive property, distribute the -7}\\\\-7y+21=-14\\\\\text{Now, we wil subtract 21 from both sides to get -7y by itself}\\\\-7y=-35\\\\\text{Divide both sides by -7}\\\\\bf y=5

Once you're done solving, you should get y = 5

This means that y would equal to 5 (y = 5).

Answer:

Step-by-step explanation:

\mathrm{Line\:passing\:through\:}\left(-1,\:-3\right)\mathrm{,\:}\left(2,\:1\right)\\\\\mathrm{Find\:the\:line\:}\\\mathbf{y=mx+b}\mathrm{\:passing\:through\:}\left(-1,\:-3\right)\mathrm{,\:}\left(2,\:1\right)\\\\\mathrm{Compute\:the\:slope\:}\left(-1,\:-3\right),\:\left(2,\:1\right):\quad \\m=\frac{4}{3}\\\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}\\\\\left(x_1,\:y_1\right)=\left(-1,\:-3\right),\:\left(x_2,\:y_2\right)\\\left\\

\\m=\frac{1-\left(-3\right)}{2-\left(-1\right)}\\\\Refine\\\\m=\frac{4}{3}\\\\\mathrm{Compute\:the\:}y\mathrm{\:intercept}:\quad b=-\frac{5}{3}\\\\y=\frac{4}{3}x-\frac{5}{3}\\

Convert equation to standard form

y - \frac{4}{3} x + \frac{5}{3} = 0\\\\Multiply \:through\: by\: 3;\\\\3\times (y - \frac{4}{3} x + \frac{5}{3} )=0\\\\3y -4x+5 = 0\\Arrange\:n\:form\:of \:;\\Ax +By = C\\\\-4x +3y =-5

The compound interest will be equal to $13.57.

<h3>What is compound interest?</h3>

The interest on a loan or deposit that accrues on both the initial principal and the accumulated interest from prior periods is known as compound interest.

The compound interest will be calculated by:-

CI = P(1+\dfrac{r}{12})^{12t}-P

CI = 250(1+\dfrac{0.053}{12})^{12}-250

CI = $13.57

Therefore the compound interest will be equal to $13.57.
