its not worth 25 points but ok here u go let's solve your equation step-by-step.

3y−1=13−4y

Step 1: Simplify both sides of the equation.

3y−1=13−4y

3y+−1=13+−4y

3y−1=−4y+13

Step 2: Add 4y to both sides.

3y−1+4y=−4y+13+4y

7y−1=13

Step 3: Add 1 to both sides.

7y−1+1=13+1

7y=14

Step 4: Divide both sides by 7.

y=2

Answer:

y=2 so there your answer is this equation has one solution your welcome

1. Write an equation in point-slope form for the line through the given point with the given slope.

ElenaW [278]

Answer: y + 2 = $\frac{-1}{2}$ ( x - 4 )

Step-by-step explanation:

The equation of a line in point - slope form is given as ;

y - $y_{1}$ = m (x - $x_{1}$ )

$x_{1}$ = 4

$y_{1}$ = -2

m = $\frac{-1}{2}$

Substitute the values into the equation , we have

y - (-2) = $\frac{-1}{2}$ ( x - 4 )

y + 2 = $\frac{-1}{2}$ ( x - 4 )

Which could be written as :

y + 2 = y + 2 = $\frac{-1}{2}$ x + 2

PLEASE HELP!!<br>Write an inequality, in slope-intercept form, for the graph below.

Bond [772]

Ok, so we know one point is (4,2) and the other is (-4, 0)

Slope: -2/-8 = 1/4

y ? 1/4x + b

0 = -1 + b

b = 1

y < 1/4x + 1

A bank loaned out $19,500, part of it at the rate of 11% annual interest, and the rest at 7% annual interest. The total interest

Morgarella [4.7K]

The amount loaned at the interest rate of 11% is $3000.

The amount loaned at the interest rate of 7% is $16,500

<h3>What are the linear equations that represent the question?
a + b = 19500 equation 1</h3>

0.11a + 0.07b = 1485 equation 2

Where:

a = amount loaned at the interest rate of 11%

b = = amount loaned at the interest rate of 7%

<h3>How much was loaned at 11% and 7%</h3>

In order to determine how much was loaned at 7%, take the following steps:

Multiply equation 1 by 0.11:

.11a + 0.11b = 2145 equation 3

Subtract equation 2 from equation 3:

0.04b = 660

Divide both sides by 0.04:

b = 16,500

Subtract 16,500 from 19,500 :

19,500 - 16,500 = $3000
