Answer:
Step-by-step explanation:
When solving for x, we want to get x all by itself on one side of the equals side. It doesn't matter which side.
In this case, we have <em>x</em><em> </em><em>+</em><em> </em><em>h</em><em>.</em><em> </em>Since we want x alone we have to get rid of the h. We can do this by subtracting h from both sides (whatever you do to one side, you have to do to the other side).
Therefore, x = r - h.
Answer:
y =3x-7
Step-by-step explanation:
y - 2 = 3(x-3)
y -2 = 3x -9
y = 3x-7
Answer:
23
Step-by-step explanation:
first, you solve for side EH, and set it equal to 33, which is the side that corresponds to EH. After you have the value for x, plug it into the equation for HG, then solve.
Answer:
B
Step-by-step explanation:
Note:
1 gal = 4 quarts
1 pint = 0.5 quart
Re-writing all the choices in dollars and quarts and calculating how much each quart costs
A) $1 per 1 quart
B) $2 per gallon = $2 per 4 quarts = $2 ÷ 4 quarts = $0.50 per quart
C) $1.50 per 2 quarts = $1.50 ÷ 2 quarts = $0.75 per quart
D) $0.50 per 1 pint = $0.50 per 0.5 quart = $0.50 ÷ 0.5 quart = $1 per quart
If you compare all of the above, it is clear that answer B ($0.50 per quart) is the cheapest rate and hence the best deal.
Answer:
b) in the vertex.
Step-by-step explanation:
In the vertex. If the parabola opens up or down the axis of symmetry is x = a where a is the x coordinate of the vertex.
If it opens to the left or right the axis is y = a where a is the y-coordinate if the vertex.
