Answer:

10+4i

Step-by-step explanation:

2*√25 + √-16.

Given

2*5+4i

Simplify the sqrts. If you are wondering where I got "i" from, "i" is √-1. "i" is short for imaginary number because there is no real number that can be a square root of a negative number. I got the 4 because it is the square root of -16

10+4i

I multiplied the 2 and the 5. This is the simplest form because you cannot add imaginary and real numbers together.

Rachel's cell phone company charges $0.10 per minute. She used 350 minutes last month and paid $84. writ and solve a linear equa

dimaraw [331]

Answer:

Step-by-step explanation:

cuz,
x equals the number of minutes so use the y slope formula

0.10(x)+the intercept = y
0.10(350)+the intercept = 84
35+the intercept = 84
the intercept = 49
so the equation is
0.10(x)+49 = y
or
1/10(x)+49 = y
1/10(300)+49=y
30+49=y
79=y
so the answer is 79 dollars
