Answer:
675 square feet
Step-by-step explanation:
It is given that 1 gallon of paint covers about 450 square feet.
To calculate how many square feet will 1.5 gallon of paint cover, we have to multiply 450 by 1.5.
1.5 gallons of paint cover = 450 × 1.5 = 675 square feet.
1.5 gallon of paint will cover 675 square feet
Two triangles are congruent if and only if their corresponding parts are congruent (CPCTC).
How it's evaluated:
(1) w - k = -7 - -5
(2) -17 - -5= = -17 + (-15)
(3) -17 + (-15) = -2
First step is change W and K and change it into it's correct number.
Second step is change the subtraction sign to it's opposite.
Third step is subtract -17 and (-15) which would give you -2
Answer:
Step-by-step explanation:
We can recognize that the parent function for all of these graphs is going to be y=x^2. What this means is that we can graph y=x^2 and then apply transformations to it to get to all of these new graphs.
1. y = -x^2 + 5
We can see that the coefficient of the x^2 term is negative which tells us that the graph will now open downwards.
We also know that we are adding 5 on the outside of the argument which means it affect vertical shift. Therefore, we will be moving 5 units up.
2. y = x^2 - 4
We can see that the only change made to this equation is subtracting 4 on the outside of the squared part of the equation. Again, this signifies vertical movement, but since it's negative we will be moving the entire y = x^2 graph down 4 units.
3. y = -x^2 - 1
What do you notice about this graph?
- negative coefficient
- subtracting 1 outside of the argument
What do these mean?
- negative coefficient: opens downwards
- subtracting 1: move entire y = x^2 graph down 1 unit
