Use the graph below to determine the number of solutions the system has. 1)
y=-3
x=4

2)
y=4x-1
y=-2x+5

3)
y=-2x
y=-2x+5

will someone please explain this out to me? It's due soon and I don't know how to do this. Thanks

b

step-by-step explanation:

given

- 2 (3x + 12y - 5 - 17x - 16y + 4 )

simplify the parenthesis by collecting like terms

= - 2 (- 14x - 4y - 1) ← distribute the parenthesis by - 2

= 28x + 8y + 2 → b

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it

d 600 because 15*10*2=300

300+300=600

step-by-step explanation:

d. you cannot tell because there are no values shown.
