Answer:

4w + 1 = -11

Step-by-step explanation:

Solving -3w - 7 = 2

By adding 7 to both sides of the equation  we get -3w = 9

to get to w = ... we need to divide both sides with -3, which gives us

w = -3. You can check this answer by putting it back into the original equation ( -3 * -3 - 7 does equal 2,  which means our solution for w is correct.

Now all we have to do is put our solution for w into the remaining equation:

4 * -3 + 1 = -12 + 1 = -11

Answer:

-11

Step-by-step explanation:

-3w - 7 = 2

-3w (- 7 + 7) = 2 + 7

-3w = 9

-3w/-3 = 9/-3

w = -3

4w + 1

4(-3) + 1

-12 + 1

-11

jekas [21]

Answer:

Roughly 20.4%

Step-by-step explanation:

Use the formula of percent of error:

| Actual number - Guess / Actual number | (100)

The actual number is 108 and the guessed number is 86:

| 108 - 86 / 108 | (100)

= | 22/108 | (100)

= | 0.2037037037 | (100)

The vertical lines indicate absolute value.  This means that anything inside of it must be turned into its positive form.  Since it is already positive, just take the signs away:

0.2037037037(100)

≈ 0.204(100)

= 20.4

Turn this into a percent:

20.4%

Martha's percent of error is 20.4%

Please tell me if I was right or not.  I really hope this helps!

neonofarm [45]

Answer:

Distance is 6.7units to the nearest tenth.

Explanation:

To solve this problem, we the distance formula. And this is given as:

D = \frac{|a x + b y + c|}{\sqrt{a^2 + b^2}}

We were given the equation:

y = 2 x + 4

This can also be rewritten as:

y – 2 x – 4 = 0.

Therefore, a = -2, b = 1 and c = -4

Also, we were given the points:

(x, y) = (–4, 11)

Making use of the above formula for distance, we have:

D = \frac{|-2\times -4 + 1\times 11 + -4|}{\sqrt{-2^2 + -4^2}}

D = \frac{15}{\sqrt{5}}

D = 6.7units (to the nearest tenth)
