Answer:

1.75=b

Step-by-step explanation:

do the equation:

-2=3/4(5)+b

-2=-3.75+b

+3.75 to both sides

1.75=b

Answer:

y=-\frac{3}{4}x+\frac{7}{4}

Step-by-step explanation:

A line going through the point (5,-2) and parallel to y=-\frac{3}{4}x-4.

  • Let's first go over the parent linear equation, y=mx+b.
  1. y is your output value that one would see after inputting an x value into an equation. In the case of the given point, -2 is our y value.
  2. x is a variable that we put into an equation. In the case of the given point for this question, 5 is our x value.
  3. m is our slope for a linear equation. Slope can be represented as a fraction whose numerator is the rise or fall of your line, and the denominator is the run of your line.
  4. b is your y-intercept.
  • If your function is parallel to y=-\frac{3}{4}x-4, then you already know that your slope is m=-\frac{3}{4}. Let's see how this impacts our parent function:

y=mx+b\\y=-\frac{3}{4}x+b

  • Now, how do we find b? This is where the given line comes into play. If our line has to go through the point (5,-2), then let's plug in these values for our x and y, and solve for b.

y=-\frac{3}{4}x+b\\-2=-\frac{3}{4}(5)+b\\ -2=-\frac{15}{4}+b\\-\frac{8}{4}+\frac{15}{4}=b\\  b=\frac{7}{4}

  • Our final equation is:

y=-\frac{3}{4}x+\frac{7}{4}

The sum of three consecutive even integers is -78. What is the smallest integer? Show all working outs (5)
svet-max [94.6K]

Answer:

The smallest integer is -27 and the integers are -27, -26, and -25

Step-by-step explanation:

We can represent this with:

x + x - 1 + x - 2 = -78

Simplify.

3x - 3 = -78

Add 3 to both sides.

3x = -75

Divide both sides by 3.

x = -25

So, the first integer is -25.

Subtract two to get the smallest integer.

-25 - 2 = - 27

2) f(x) = x² **<br> g(x)= 3x – 2<br> Find f(g(-4)
Usimov [2.4K]

Answer:

f(g( - 4)) = 196

Step-by-step explanation:

The functions are;

f(x) =  {x}^{2}

and

g(x) = 3x - 2

We want to find

f(g( - 4))

First we find g(-4) to get:

g( - 4) = 3 \times  - 4 - 2

g( - 4) =  - 12- 2

g( - 4) =  - 14

Now

f(g( - 4)) = f( - 14)

This implies that,

f(g( - 4)) = {( - 14)}^{2}

f(g( - 4)) = {( - 14)} \times  - 14

f(g( - 4)) = 196
