What is the slope of 6x+10y=8 (choice A) A -3/4 B -5/4 C -3/5 D -4/5

Mathematics

Answer:

C

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 )

Rearrange 6x + 10y = 8 into this form by subtracting 6x from both sides

10y = - 6x + 8 ( divide all terms by 10 )

y = - \frac{3}{5} x + \frac{4}{5} ← in slope- intercept form

with slope m = - \frac{3}{5} → C

  pct change = ((new value)/(original value) -1) × 100%

  = (50/140 -1) × 100%

  = (-9/14)×100% = -64 2/7% ≈ -64.3%

Derick says "bruh" 400 times in 5 days, and he also says "bruh" 925 times in 12 days. What is the rate of change?
Oduvanchick [21]

Answer:

The answer is 75.

Step-by-step explanation:

Average rate of change = Δy/Δx

y^2 -  y^1/x^2 - x^1

925 - 400/12 - 5 = 525/7 = 75

6-8x=7x-10x-24 solve for x
lana66690 [7]

Answer:

x = 6

Step-by-step explanation:

Let's solve your equation step-by-step.

6−8x=7x−10x−24

Step 1: Simplify both sides of the equation.

6−8x=7x−10x−24

6+−8x=7x+−10x+−24

−8x+6=(7x+−10x)+(−24)(Combine Like Terms)

−8x+6=−3x+−24

−8x+6=−3x−24

Step 2: Add 3x to both sides.

−8x+6+3x=−3x−24+3x

−5x+6=−24

Step 3: Subtract 6 from both sides.

−5x+6−6=−24−6

−5x=−30

Step 4: Divide both sides by -5.

−5x/-5 = -30 /-5

x=6
