Answer:
whats the question?
Step-by-step explanation:
You would add the 30 to the 40 And then add 45 to that and you will get 112
Answer:
Step-by-step explanation:
A)
y=−2x+4
y-int:
y=−2*0+4
y=4
x-int:
0=−2x+4
2x=4
x=2
(2,4)
B)
2x+3y=6
y-int:
2*0+3y=6
3y=6
y=2
x-int:
2x+3*0=6
2x=6
x=3
(3,2)
C)
1.2x+2.4y=4.8
y-int:
1.2*0+2.4y=4.8
2.4y=4.8
24y=48
y=2
x-int:
1.2x+2.4*0=4.8
1.2x=4.8
12x=48
x=4
(4,2)
Answer:
x=7
y=10.5
Step-by-step explanation:
1. You can apply the method of substitution, as you can see below:
- Substitute
into the other equation and solve fo x:

- Substitute the value of x obtain into the first equation, then the value of y is:

Vertex form 1/2(0), where 0 replaces x as a number the variable x is.
The vertex is (0,0).
