Solve the system by graphing: y=-3x-3 and y=2x+2. Make sure you write your answer as an ordered pair: (x,y)

Rainbow [258]

Answer: (5, 12)

Step-by-step explanation:

Just graph the linear equations and find where they intersect.

Algebraically, you can set them equal to each other

-3x-3=2x+2

-x-3=2

-x=5

x=5

Plug x=5 to any equation

y=2(5)+2

y=12

Gabriela walked to school on 16 of the 24 school days in March. Which value is equivalent to the fraction of the school days in

olchik [2.2K]

Answer:

$\frac{2}{3}$

Step-by-step explanation:

A fraction is a quantity that is not a whole number. In maths, a fraction usually has a numerator and a denominator.

The numerator is the number above. While the denominator is the number below

an example of a fraction = $\frac{4}{5}$

4 is the numerator while 5 is the denominator

In this question, the numerator would be the number of times she walked to school in march(16). While the denominator would be the number of school days in March

$\frac{16}{24}$

the above fraction is not in its simplest form. To express in its simplest form, divide both numerator and the denominator by 8 . this gives

$\frac{2}{3}$
