Find the slope of the line. 5x – 2y = 7
nika2105 [10]

Answer:

Final answer is slope m=\frac{5}{2}

Step-by-step explanation:

Given equation is 5x-2y=7

Now question says to find the slope.

Since given equation 5x-2y=7 is a linear equation so we need to compare 5x-2y=7 with slope intercept formula y=mx+b to get the value of slope m.

Since 5x-2y=7 is not in that form so first let's rewrite it in y=mx+b form

5x-2y=7

-2y=-5x+7

y=\frac{-5x+7}{-2}

y=\frac{5}{2}x-\frac{7}{2}

Now comparing with y=mx+b, we get m=\frac{5}{2}

Hence final answer is slope m=\frac{5}{2}

Answer:

  D.  Henry's started farther, went faster

Step-by-step explanation:

Henry's balloon traveled 18 additional miles (from 30 to 48) in 2 hours, so had a speed of 18mi/(2h) = 9 mi/h. The equation for his position could be ...

  y = 9x +30 . . . . . 9 is the rate of change; 30 is the initial value

__

Comparing this to Tasha's position function, we see her balloon started 20 miles from town and traveled 8 miles per hour.

__

Henry started farther from town and traveled faster.

Which situation could be represented by the equation 15.5 = x/2
jok3333 [9.3K]

Answer:

C. Julie drive 15.5 miles from her home to the grocery store. Julie drives the same path going back home. What is x, the total amount of miles traveled to the grocery store and back home?

Step-by-step explanation:

The situation in the 3rd option represents the equation, 15.5 = x/2.

Distance driven by Julie to the grocery store = 15.5 miles

Distance driven by Julie back home following the same path = 15.5 miles

Total amount of miles travelled to and fro the store, x, = 2*15.5

This means, the mile's covered going to the store or coming back home can be expressed as ½ the total amount of miles, x, covered. Which is: 15.5 = ½x

Therefore, the third option represents the equation, 15.5 = x/2.
