Answer:  \bold{C)\quad -\dfrac{1}{2}}

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

\dfrac{x+2}{15}=\dfrac{x+1}{5}\\\\\\\underline{\text{Multiply both sides by the LCD (15) to eliminate the denominator:}}\\x+2=3(x+1)\\x+2=3x+3\\.\quad \ 2=2x+3\\.\quad -1=2x\\\\.\quad \large\boxed{-\dfrac{1}{2}=x}

Somebody please explain this I have a major exam soon and I really need to know how to solve problems like this​
nevsk [136]

Answer:

y = 2x - 3

Step-by-step explanation:

Step 1: Find the slope. You find the slope by using the formula y2-y1/x2-x1. (2, 1) and (4, 5) are our points. Let's find our values.

y2= 5

y1= 1

x2 = 4

x1 = 2

Plug in the numbers into the equation. 5 - 1 is 4. 4 - 2 is 2. 4/2 is 2. There. Our slope is 2.

Step 2: Find the b value. Keep in mind that an equation in point-slope form is y = mx + b, where m = the slope, and b = the y-intercept. For this part, you will plug in one of the points as x and y to find the b value. let's use point (4, 5)

The equation then becomes 5 = 2(4) + b. As we know, 2 * 4 is 8. Subtract 8 on both sides of the equation to cancel out the right side and isolate the b variable. 5 - 8 is -3. Even if you use the other point for the equation (1 = 2(2) +b), you should get the same answer of -3.

A= 1/2 h(a+b) solve for b
irakobra [83]

Answer and Step-by-step explanation:

Solve for b.

A = (\frac{1}{2}) (h)(a+b)

Divide by h and multiply by 2 from both sides.

\frac{2A}{h} = a+ b

Subtract a from both sides.

(\frac{2A}{h} ) - a = b
