Answer:

y = \frac{5}{2} x + 4

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = \frac{5}{2}, thus

y = \frac{5}{2} x + c ← is the partial equation

To find c substitute (- 2, - 1) into the partial equation

- 1 = - 5 + c ⇒ c = - 1 + 5 = 4

y = \frac{5}{2} x + 4 ← equation of line

if anyone can solve this gets a $10 gamestop card i already got the codeSolve for x. Show each step of the solution. 2.5(10 - x)
schepotkina [342]

Remark

Forget the Gamestop. I'd never use it. This one is on the house.

Solution

2.5(10 - x) + 10 = 72 - 1.5x*(5x + 12)   The first step is to remove the brackets.  Be very careful you understand the bracket on the right.

25 - 2.5x + 10 = 72 - 7.5x - 18            Study the signs carefully. Collect like terms.

35 - 2.5x = 54 - 7.5x                   Add 7.5x to both sides.

35 - 2.5x + 7.5x = 54 - 7.5x + 7.5x

35 + 5x = 54                               Subtract 35 from both sides.

5x = 19                                        Divide by  5

x = 19/5

x = 3 4/5 = 3.8

Check

When you numbers are so cumbersome, you should check the answer.

<em><u>LHS</u></em>

2.5(10 - 3.8) + 10

2.5(6.2) + 10

15.5 + 10

25.5

<em><u>RHS</u></em>

72 - 1.5(5*3.8 +12)

72 - 1.5(19 + 12)

72 - 1.5(31)

72 - 46.5

25.5

<em><u>RHS = LHS</u></em> The solution checks.

Helppp please, i don’t know how to do this
masya89 [10]

Answer:

Line CB

Step-by-step explanation:

We know the smallest triangle is the left triangle, so you need to find the smallest angle in that triangle, which is 50 degrees as shown, and the opposite side to that, CB, is the smallest side.
