Answer:
This is a vertical line, that passes through x=-2
Step-by-step explanation:
This is a vertical line, x=-2 means that no matter what value has 'y' the variable 'x' will be -2.
Watch the attached picture
Equation 1. N+D=500
equation 2 5N+10D=3000
This is for equation 1
N=500-d
Substitute into equations 2 and solve for D
5N+10D=3000
5(500-D)+10D=3000
2500-5D+10D=3000
5D=500
D=100
Lets go back the equation 1
N=500-D
N=500-100
N=400
there are 400 Nickles and 100 Dimes
1.7,5-1,5=6
2.10-11=-1
3.6×-1=-6
4.-6+2=-4
Answer:
y = -13/16
Step-by-step explanation:
<u>Given:</u>
0.8y+0.25= -0.4
<u>To Find:</u>
Solve for y
<u>Solution:</u>
Multiply both sides by 100

Simplify

Subtract 25 from both sides

Simplify

Divide both sides by 80

Simplify

Thus, y = -13/16
or in decimal form it equal y = -0.8125

Answer:
Step-by-step explanation:
Total height lowered = 75m
No of times balloon lowered = 5
Height lowered in each lowering = Total height lowered / No of times balloon lowered
= 75 / 5
= 15 m
The number indicated that each time balloon is lowered by 15 m
