Answer:

x = 8.4

y = -2

Step-by-step explanation:

Step 1: Sub y=-2 into y=5x + 40

-2 = 5x + 40

Step 2: Solve for 'x'

-2 = 5x +40

-42 = 5x

x = 42/5

x = 8.4

Step 3: Solve for 'y'

y is given in the question, y=-2

That should be negative 4 as it divided into 40

A line with a slope of 3/2 passes through (4,-1). Write the equation.
RideAnS [48]
Hey there!

We're going to write the equation for this line in slope-intercept form, y = mx+b, where m is the slope and b is the y-intercept. In order to write it in this form, as stated in the name, we need the slope and y-intercept. Since we have the slope given, we can use the points we have and set up that equation with the given slope to solve for b. We'll use the x and y values and throw them into the equation. We have:

-1 = 3/2(4) + b
-1 = 12/2 + b
-1 = 6 + 6
-6 = b

Now, since we have our slope and y-intercept, we can write our equation with these two values:

y = 3/2x - 6

Hope this helps!

Could someone please help mee<br> Step by step
Keith_Richards [23]

Let Q be the point (a, b). Since the midpoint of P (2, 3) and Q (a, b) is (4, 6), we have

(2 + a)/2 = 4

(3 + b)/2 = 6

Solve for a and b :

(2 + a)/2 = 4

2 + a = 8

a = 6

(3 + b)/2 = 6

3 + b = 12

b = 9

So the coordinates of Q are (6, 9).
