Answer:

A = - 2 and B = - 8

Step-by-step explanation:

A = - 2 and B = - 8 will create infinitely many solutions for this system of equations

When you add both equations together and both sides are equal then the systems have infinitely many solutions

-2x - y = 8

2x + y = -8

--------------------Add

0 = 0

Both sides are equal 0

Infinitely many solutions

FrozenT [24]

Answer:

$\frac{25}{4}$

Step-by-step explanation:

a + b = $\frac{1}{2}$ + 2 = 2 $\frac{1}{2}$ = $\frac{5}{2}$ , thus

(a + b)² = ( $\frac{5}{2}$ )² = $\frac{5}{2}$ × $\frac{5}{2}$ = $\frac{5(5)}{2(2)}$ = $\frac{25}{4}$

Answer:

48°
60°
72°

Step-by-step explanation:

The sum of ratio units is 4+5+6 = 15, so each unit stands for 180°/15 = 12°. Multiplying the ratio units by 12° gives the angle values:

4×12° : 5×12° : 6×12° = 48° : 60° : 72°

Angles 1 to 3 are 48°, 60°, 72°, respectively.

Rob is saving to buy a new MP3 player. For every $14 he earns babysitting, he saves $6. On

abruzzese [7]

Answer:

Rob has saved $24.

Step-by-step explanation:

The first thing I noticed was that Rob only saved some of the money he earned. That means only x% only gets saved. To find x, I simply divided 6 by 14 and got 0.42857142857. Then to find the amount he saved from earning $56, I multiplied that number with 56 and got 24.
