x = 5 and y = 8
Step-by-step explanation:
y = 3x - 74x - 5y = -20→ Subtitute the value of y to second equation :
4x - 5y = -20
4x - 5(3x - 7) = -20
4x - 15x + 35 = -20
-11x + 35 = -20
-11x = -20 - 35 → (multiplied by -1)
11x = 20 + 35
11x = 55
x = 5
→ Subtitute x to one of Equation :
For example i take from First Equation…
y = 3x - 7
y = 3(5) - 7
y = 15 - 7
y = 8
∴ So, the value of x = 5 with y = 8

22 > 16
Which of the following statements describes the graph below?
PLS HELP.
Answer:
piecewise, continuous.
Step-by-step explanation:
This is piecewise simply because it is in pieces. Thus PIECEwise (Pun intended). This is continuous because, as you can see, there is a filled in dot on the same x coordinate as every empty dot. The empty dots mean that that value is not in that part of the graph. However, since the other parts of the function "fill the gaps," then it is continuous. I hope this helps!
It's offcourse piecewise
For continuity
Observe the graph
The domain is like
(-oo,1]U(1,2]U(2,oo)For close ineterval there is an open interval hence it's continuous
solve the eequation show all your work g + 5 = 7 1/5
Answer:
Move all terms not containing
g
to the right side of the equation.
Exact Form:
g
=
46/5
Decimal Form:
g
=
9.2
Mixed Number Form:
g
=
9 1/5
.:
Answer:
g = 2 1/5
Step-by-step explanation
get g by itself by canceling out the 5
whatever you do to one side you have to do to the other side.
5-5 leaves you with nothing but the g on the left side of the equals sign
7 1/5 -5= 2 1/5
so your left with g= 2 1/5
g + 5 = 7 1/5
-5 -5
g = 2 1/5

please show steps on how to do
Answer:
x=-5
Step-by-step explanation:
-5*-3=15
15-2=13
Hope it helps
Answer:
x = -5
Step-by-step explanation:
-3x-2=13
Add 2 to both sides of the equation
-3x-2+2=13+2
Simplify
-3x=15
Divide both sides of the equation by the same term
[tex]\frac{-3x}{3} =\frac{15}{-3}[/tex]
Simplify
x = -5
