Answer:

y=\frac{7}{4}x-9

Step-by-step explanation:

Question:

Find the equation of the line through the point (4, -2) with slope \frac{7}{4}

Answer + Step-by-step explanation:

Answer: y=\frac{7}{4}x-9

Step-by-step explanation:

When trying to find the equation of a line passing through a point and then given the slope, always remember if you're trying to write the equation in slope-intercept form, find the slope and the y-intercept of the equation.

Slope-Intercept form: y = mx + b where m = slope and b = y-intercept

so the slope is already given but we have to find the y-intercept.

so... the equation of the line with a slope of \frac{7}{4} is:

y=\frac{7}{4}x

but in addition, we need a y-intercept so...

y=\frac{7}{4}x+b

now use the given point on the question "(4, -2)" to solve for the y-intercept

so plug in the coordinates of the point in the equation:

y=\frac{7}{4}x+b

(-2)=\frac{7}{4}(4)+b

-2=\frac{28}{4} +b

-2=7+b

b=-2-7

b=-9

so the y-intercept of the line is -9

and the equation of the line is y=\frac{7}{4}x-9

A linear inequality to represent the algebraic expression is given as 492.46 - x ≥ 500

<h3>Linear Inequality</h3>

Linear inequalities are inequalities that involve at least one linear algebraic expression, that is, a polynomial of degree 1 is compared with another algebraic expression of degree less than or equal to 1.

In this problem, her minimum balance must not decrease beyond $500 or she will pay a fee.

where

  • x = withdrawals

The inequality to represent this can be written as

524.96 - 32.50 - x ≥ 500

Simplifying this;

492.46 - x ≥ 500

The linear inequality is 492.46 - x ≥ 500

2. attached below even though I answered I was guessing this question so I need to know the correct answer
zavuch27 [327]

Volume is defined as area of the base*the hight.

In this question the base is the traingles.

Area of a triangle is base*hight/2, so it 8*6/2= 24

Volume is 24*8(hight)=192

So the answer is 192cm^3

What is the difference of the fractions? Use the number line and equivalent fractions to help find the answer.
Dmitry_Shevchenko [17]

Answer:

  (c)  -3/4

Step-by-step explanation:

Subtracting a positive number moves you to the left on the number line. Subtracting a negative number moves you in the opposite direction, to the right.

Here, we start at -2 1/2 = -5/2, and we move 1 3/4 = 7/4 to the right from there. Each mark on this number line is 1/4 unit, so we move 7 marks. The results is ...

  -2 1/2 -(-1 3/4) = -5/2 +7/4

  = -10/4 +7/4 = -3/4
