Answer:
Step-by-step explanation:
y = -x + 2 -------(i)
2x - y = -5 -----------(ii)
Substitute y = -x + 2 in equation (ii)
2x - (-x + 2) = -5
2x + x - 2 = - 5
3x - 2 = -5 {add 2 to both side}
3x -2 + 2 = -5 + 2
3x = -3 { divide both sides by 3}
3x/3 = -3/3
x = -1
Plug in the value of x in equation (i)
y = - (-1) + 2
y = 1 +2
y = 3

The area of a triangle is related to the base and height of the triangle by the formula a = bh/2. Rewrite this equation with b solved in terms of a and h.
Answer: b = 2a/h
Step-by-step explanation:
a = bh/2
multiply each side by 2
2a = bh
divide each side by h
2a/h = b
Answer:

20 POINTS! The following graph shows the amount of money Jonah earns when he babysits for the family who lives next door. Based on the graph, which of the following statements are true? Select ALL that apply.
When Jonah babysits one hour, he earns $7.50.
The equation e = 4 h can be used to describe this situation.
Jonah earns $20 to babysit for 5 hours.
The number of hours Jonah works depends on how much he earns.
Answer:
The equation e = 4 h can be used to describe this situation.
Jonah earns $20 to babysit for 5 hours.
Step-by-step explanation:
When Jonah babysits one hour, he earns $7.50.
looking at the graph we see at 1 hour he earns 4 dollars false
The equation e = 4 h can be used to describe this situation.
The slope is 4 so y = 4x e = 4h would also work true
Jonah earns $20 to babysit for 5 hours.
Using our equation from above
e = 4*5 = 20 true
The number of hours Jonah works depends on how much he earns.
This would be false
The dependent variable is on the y axis. The amount he earns depends on how much he works

The density of oxygen is 0.001332 gram per cubic meter. Represent 0.001332 in scientific notation.
Answer:
1.332 × 10-3
Step-by-step explanation:
you move the decimal point to the right until there's only one digit on the left side of it. the exponent is 3 because that's the number of places you moved the decimal point, and it's negative because you moved it to the right. if you move the decimal to the left it is positive, to the right is negative :)
By basic calculation We can represent 0.001332 in scientific notation as [tex]1.332\times 10^{-3}[/tex]
What is scientific notation?Scientific notation is a way of expressing numbers big numbers in short form with approximate values.
Given number is 0.001332
we can write 0.001332 as
1332/1000000
or we can write it as
1.332/1000
and now we can write it in Scientific notation form as
[tex]\frac{1.332}{10^3}\\\\1.332\times 10^{-3}[/tex]
By basic calculation We can represent 0.001332 in scientific notation as [tex]1.332\times 10^{-3}[/tex]
