0=(-9)

Step-by-step explanation:

4x + 7 = -2 + 4x

4x + 7 = 4x -2

subtract 7 from both sides of the equation.

simplify your answer.

subtract 4x from both sides of the equation.

simplify your answer again.

4x + 7 = 4x -2

<u>_</u><u>_</u><u>_</u><u>-</u><u>7</u><u> </u><u>=</u><u> </u><u> </u><u>4</u><u>x</u><u> </u><u>-</u><u>7</u><u> </u>

<u> </u><u>4</u><u>x</u><u> </u><u>_</u><u>_</u><u> </u><u>=</u><u> </u><u> </u><u>4</u><u>x</u><u> </u><u>-</u><u>9</u>

<u>_</u><u>_</u><u>4</u><u>x</u><u> </u><u>=</u><u> </u><u>4</u><u>x</u><u> </u><u>-</u><u>9</u>

<u> </u><u>-</u><u>4x = -4x</u><u> </u><u>-</u><u>9</u>

<u>_</u><u>_</u><u>0</u><u> </u><u>=</u><u> </u><u> </u><u>-</u><u>9</u>

the input is a contradiction: it has no solutions.

What’s the answer hurry
Rina8888 [55]

Answer:

Choice C: Lauren is faster than Kevin, slower than Jeremy.

Step-by-step explanation:

Ok, so it directly says that Jeremy is going at y=12x, or 12 miles per hour. To find how fast Kevin is riding, take two points of the table and use the slope formula to get the speed(.

Slope Formula: (y2-y1) / (x2-x1)

So lets take the table plots (2, 22) and (4, 33) to do this.

(y2-y1) / (x2-x1)

(33-22) / (4-2)

(11) / (2)

The speed of Kevin is 5.5 miles by hour.

Then, it asks for how fast Lauren is going, saying she is twice as fast as Kevin. Therefore, simply do:

5.5 * 2 = 11 miles per hour

To get the third biker's speed.

Now, with all of the speeds of the bikers, we can now compare them. Here's a listing of their speeds to make things easier to compare:

Jeremy: 12 mph

Kevin: 5.5 mph

Lauren: 11 mph

From this, we can see that Lauren is the second fastest. She is slower than Jeremy but faster than Kevin. Therefore, the correct answer choice is C.

Write an equation in slope-intercept form for the line with slope 8 and y-intercept -8.​
Fofino [41]

Answer:

y = 8x - 8

Step-by-step explanation:

y = mx + b is slope-intercept form

m - slope

b - y-intercept

so if you plug in 8 for m and -8 for b you'll get

y = 8(m)x - 8(b)

Hope this helps!!

Given: m∠LOI=38° m∠JOP=84° Find: m∠JKP
grigory [225]

Answer:

84°

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one.  Please have a look at the attached photo.

Given that:

  • ∠LOI=38°
  • ∠JOP=84 °

As we can  see from the figure that ∠JOP and ∠JKP are on the same segment JP. Hence, ∠JOP and ∠JKP are congruent and the angle of ∠JKP is 84°
