Which shows the equation y – 4 = 2(x + 3) written in standard form? A. –2x + y = 10 B. –2x + y = 7 C. y = 2x + 7 D. y = 2x + 10

Answer:

A. $-2x+y=10$

Step-by-step explanation:

Given:

The equation of a line is given as:

$y-4=2(x+3)$

The standard form of an equation of a line is of the form:

$Ax+By=C$ , where, A, B and C are constants.

Now, we have to rearrange the above equation in standard form.

$y-4=2(x+3)$

Distribute 2 to $x+3$ . This gives,

$y-4=2x+6$

Add 4 on both sides. This gives,

$y-4+4=2x+6+4\\y=2x+10$

Now, add -2x on both sides. This gives,

$y-2x=2x-2x+10\\y-2x=10$

Now, rearrange in standard form. This gives,

$-2x+y=10$

Therefore, the standard form is given as $-2x+y=10$

State the degree: 11m^3n^2p

Vadim26 [7]

<h3>Answer: 6</h3>

Explanation:

Using the rule that x = x^1, we can rewrite the p as p^1

So 11m^3n^2p is the same as 11m^3n^2p^1

The exponents are: 3, 2, 1

Those exponents add up to 3+2+1 = 6

The degree of a monomial like this is simply equal to the sum of the exponents.

Paul travel to the lake and back. The trip took 3 hours and the trip back took 4 hours He averaged 10 mph faster on the trip the

ollegr [7]

Answer:

40 mph

Step-by-step explanation:

We assume "outbound" refers to the trip <em>to the lake</em>. The ratio of speeds is inversely proportional to the ratio of times, so ...

outbound speed : inbound speed = 4 : 3

These differ by one ratio unit, so that one ratio unit corresponds to the speed difference of 10 mph. Then the 4 ratio units of outbound speed will correspond to ...

4×10 mph = 40 mph

Paul's average speed on the outbound trip was 40 mph.

___

The distance to the lake was 120 mi.
