What is the solution of the system? use a graph.
y = x + 5
y = –5x – 1

x=-1

y=4

check the graph added

Step-by-step explanation:

Hello

(1)y = x + 5  

(2)y = –5x – 1

Here we have two linear functions, the point of intersection of the two lines is the solution coordinate (x, y)

using a graph as asked by the question  we can figure out the intercept

I=(-1,4) hence

x=-1

y=4

let´s check in the equations

(1)y=x+5

4=-1+5

4=4,ok

(2)y=-5x-1

4=-5(-1)-1

4=+5-1

4=4,ok

check the graph added

Have a great day

the fist one is not equalvalent but i think th second one isand the third isnt definetly or the last one is i think. hope this !

step-by-step explanation:

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls
