Answer:

x=10

Step-by-step explanation:

One approach is to try them all out. For x=10 you have a winner, since (10-3)(10-5) = 7*5 = 35.

You can also work out the brackets, and refactor the equation. You will then get

(x+2)(x-10) = 0,

so x=-2 is another solution.

Answer:

x = 10

x = -2

Step-by-step explanation:

I'll solve it.

Open parentheses:

x^2 - 8x + 15 = 35

x^2 - 8x - 20 = 0

(x - 10)(x + 2) = 0

x = 10, x = -2

Answer:

$-\frac{13}{4}$

Step-by-step explanation:

8 - 4s = 8 + 13

8 - 4s = 21

4s = 8 - 21

4s = - 13

s = -13/4

Convert to standard form of the equation into the slope intercept form -3x-5y=-15

Mamont248 [21]

Our goal is to get y by itself
We will first add 3x to both sides to get
-5y = 3x - 15
We will then divide both sides by -5 to get y by itself which becomes
y = -3/5x + 3

Answer:

x=6

Step-by-step explanation:

Kindly look at the image provided below.

The image shows the relationship between intersecting secants and their corresponding arcs which is important to understand when looking at problems like these.

The relationship states that an angle formed by two intersecting secants is equal to half the sum of its corresponding arc and its vertical angles corresponding arc.

So ∠FHG = 1/2 ( arc FG + arc EB )

* substitute the given expressions for each angle and arc *

we would then have

15x - 2 = 1/2 ( -2 + 12x + 16x + 10 )

We now solve for x

Step 1 multiply each side by 2

1/2 ( -2 + 12x + 16x + 10 ) *2 = ( the 2 and 1/2 cancels out ) -2 + 12x + 16x + 10

(15x - 2 )2 = 30x - 4

we now have -2 + 12x + 16x + 10 = 30x - 4

step 2 combine like terms

-2 + 10 = 8

12x + 16x = 28x

now we have 30x - 4 = 28x + 8

step 3 add 4 to each side

-4 + 4 cancels out

8 + 4 = 12

Now we have 30x = 28x + 12

step 4 subtract 28x from each side

30x - 28x = 2x

28x - 28x cancels out

now we have 2x = 12

step 5 divide each side by 2

2x / 2 = x

12 / 2 = 6

we're left with x = 6
