-4x+15x+18=14x+7-3x

-4x+15x=11x

11x+18=14x-3x+7

14x-3x=11x

11x+7

11x+18=11x+7

Ana is 555 years younger than her sister, Beatriz. 1. Write an equation that represents how old Ana is (a) when Beatriz is b yea
White raven [17]

Answer:

1. B-555

2. -532

Step-by-step explanation

1. Since Ana is 555 years younger you would have to find the difference between their ages, since Ana is younger you would subtract her age, B, from her sister's, Beatriz age, who is 555 years older.

2. If Beatriz is 23 and Ana is 555 years younger you just subtract 555 from 23, which is negative 532

Answer:

y = 11x

Step-by-step explanation:

First we find the slope

m = (y2-y1)/(x2-x1)

   = (11-0)/(1-0)

   = 11/1

=11

We know the y intercept is 0 ( the y value where x is zero)

We can use the slope intercept form of the equation for a line

y = mx+b where m is the slope and b is the y intercept

y = 11x+0

y = 11x

Aiko is finding the sum (4 + 5i) + (–3 + 7i). She rewrites the sum as (–3 + 7)i + (4 + 5)i. Which statement explains the error A
anyanavicka [17]

Answer:

Option 5

Step-by-step explanation:

Aiko incorrectly used the distributive property by combining the real number and the coefficient of the imaginary part.

It is wrong because 'i' is with 5 and 7 and it is not present in -3 and 4

(4 - 3) + i(5 + 7) would have been the correct way to write it

PLEASE RATE! I hope this helps!
