180+8x=160+6x help me find x

lianna [129]

Answer:

x = -10

Step-by-step explanation:

Step 1: Write equation

180 + 8x = 160 + 6x

Step 2: Solve for x

Subtract 6x on both sides: 180 + 2x = 160
Subtract 180 on both sides: 2x = -20
Divide both sides by 2: x = -10

Step 3: Check

Plug in x to verify it's a solution.

180 + 8(-10) = 160 + 6(-10)

180 - 80 = 160 - 60

100 = 100

Find the slope of the function f ( x ) = 5x/2 + 3, by the definition of limit. Express answer as a fraction using the "/" key as

musickatia [10]

$\huge{\boxed{\frac{5}{2}}}$

Slope-intercept form is $f(x)=mx+b$ , where $m$ is the slope and $b$ is the y-intercept.

$\frac{5x}{2}=\frac{5}{2}x$ , so change the equation to represent this. $f(x)=\frac{5}{2}x+3$

Great! Now the function is in slope-intercept form, so we can just see that $m$ , or the slope, is equal to $\boxed{\frac{5}{2}}$
