Answer:

if y = 5 than 2x - 5 = 5 we can simplify this too 2x = 10 ( by adding the 5 to both sides ) now we can simplify and get x = 5 ( by dividing by 2 ) so we get (5,5) as our first point. well since its in slope intercept form ( y = mx + b ) we can graph it.

50+x(greater than or equal to)300

nikdorinn [45]

Answer:

x ≥ 250

Step-by-step explanation:

Note that "greater than or equal to" looks like ≥

50 + x ≥ 300

Isolate the variable. What you do to one side, you do to the other. Subtract 50 from both sides.

x + 50 (-50) ≥ 300 (-50)

x ≥ 300 - 50

x ≥ 250

x ≥ 250 is your answer.

Sam is driving from Chicago to San Francisco, a distance of 2220 miles. He covers the first 192 miles in 4 hrs. At this rate, ho

Citrus2011 [14]

We can set it up like this:

$\frac{192}{4} = \frac{2220}{x}$

This states that Sam can drive 192 miles in 4 hours and 2220 miles in x hours. To solve, we can use cross-multiplication:

$192x = 2220*4 \\ 192x = 8880 \\ x = \frac{8880}{192} \\ x = 46.25$

It will take Sam 46.25 hours to drive the whole trip, or 46 hours and 15 minutes.
