4 0

Answer:

a. 2x -3

b. 7

Step-by-step explanation:

a. The expression that represents the difference is sales between the two sales will be:

9x - (7x + 3) = 9x - 7x - 3 = 2x - 3

b. What we do here is to simply substitute the value of 5 for x

mathematically, we have to substitute the value of 5 in the expression above

We have this as:

2(5) -3

= 10-3 = 7

If f(x)= negative -3x +4 and g(x)=2 solve for the value of X for the which f(x) =g(x) is true
Sever21 [200]

Answer:

x = -2/3

Step-by-step explanation:

Step 1: Convert signs

f(x) = -(-3x) + 4

f(x) = 3x + 4

Step 2: Set f(x) and g(x) equal to each other and solve for <em>x</em>

3x + 4 = 2

3x = -2

x = -2/3

And we have our final answer!

6. Answer: y = 5x - 11

<u>Step-by-step explanation:</u>

Parallel means "same slope".  y = 5x - 2 is in the form y = mx + b,

so the slope (m) = 5

Next, input the point (x₁, y₁ = 2, -1) and slope (m = 5) into the Point-Slope formula:

y - y₁ = m(x - x₁)

y - (-1) = 5(x - 2)

y + 1 = 5x - 10

y      = 5x - 11

7. Answer: \bold{y = \dfrac{1}{3}x + 4}

<u>Step-by-step explanation:</u>

Perpendicular means "opposite reciprocal slope". y = -3x + 7 is in the form y = mx + b, so slope (m) = -3 ⇒ m⊥ = \frac{1}{3}

Next, input the point (x₁, y₁ = 3, 5) and slope (m = \frac{1}{3} ) into the Point-Slope formula:

y - y₁ = m(x - x₁)

y - 5=\dfrac{1}{3}(x - 3)

y - 5 =\dfrac{1}{3}x - 1

   y=\dfrac{1}{3}x + 4
