Will this parabola open upward or downward? How can you tell the direction that it opens from looking at the graph?
y = -5x² + 3x - 4
I know the parabola will open downward because the leading coefficient of the equation, being -5, is negative/less than zero.
-6 (-8) Do you multiply or divide do you change the -8 to 8?
Answer:
You multiply the two together and the -8 inside the parenthasese get turned into a positive 8
Step-by-step explanation:

Two lines intersect. Find the value of b and c.
bº
42°
Answer:
b=42 degrees
c= 138 degrees
Step-by-step explanation:
B and the 42 degrees shown are congruent angles so therefore both are 42 degrees
To find C: We know that combining the 42 degrees and Angle C would form a flat angle or 180 degree angle, so therefore
subtract 180 with 42 to get Angle C
180-42= 138
Answer:
b=42, c=138
Step-by-step explanation:
B has to equal 42 because b is opposite of the 42º
and since 42+2c+42 has to equal 360, we simplify the expression to get:
84+2c=360,
2c=276
c=138
Use prime factorization to reduce the fraction 36/180
Answer:
Step-by-step explanation:
36 = 6* 6 = 2* 3 * 2* 3 = 2*2*3*3
180 = 2 * 2 * 3 * 3 * 5 = 2 * 2 * 3*3*5
[tex]\frac{36}{180}= \frac{2*2*3*3}{2*2*3*3*5} = \frac{1}{5}[/tex]

Answer:
Equation: y = 2.5x
Answer: 43.75 drawers
Step-by-step explanation:
Equation: 10 - 7.5 = 2.5 and when you subtract 2.5 until the Number of Drawers (x) is 0, then you get 0 for Total Volume (y), so y =2.5x+0 or y = 2.5x
Answer: Substitute 17.5 into x.
y = 2.5(17.5)
y = 43.75 drawers
Y=-3x^2-18x-28 solve In vertex form show work
let's one two and three have the following relationships <1and <2 are adjacent right angles <1 and <3 are vertical angles what is the measurement of <1 plus the measure of <3 minus the measure of two
Answer:
180 Vertical angles are opposite angles that share only a vertex. Since ∠3 is adjacent to both ∠1 and ∠2, this means that ∠3 shares a side and vertex with both of these angles.
This means that ∠3 and ∠1 form a straight line; this makes them a linear pair, which makes their sum 180°.

Tennis balls: Must rebound approximately 111 cm when dropped from 200 cm. Soccer balls: Must rebound approximately 120 cm when dropped from 200 cm onto a steel plate. Basketballs: Must rebound approximately 53 .5 inches when dropped from 72 inches onto a wooden floor. Squash balls: Must rebound approximately 29 .5 inches when dropped from 100 inches onto a steel plate at 70∘ Which ball listed above is the bounciest
Answer:
There is no basis for comparison because the effect of the other variables that are not being studied are not minimized
Step-by-step explanation:
The rate at which each type of ball bounce are;
Tennis balls;
The height to which the ball is must rebounds ≈ 111 cm
The height from which the ball is dropped = 200 cm
Surface = Steel plate
Basketballs;
The height to which the ball must rebounds ≈ 5.35 inches
The height from which the ball is dropped = 72 inches
Surface = Wooden floor
Squash balls
The height to which the ball must rebounds ≈ 29.5 inches
The height from which the ball is dropped = 100 inches
Steel plate at 70°
Therefore, given that the experimental are performed with different variables of height from which each type of ball is dropped, the surface to which the ball is dropped, the angle of the surface to which the ball is dropped, there is no controlled variable to provide a basis for comparison

Alana is cooking a turkey. It takes 4 1/2 h to cook. She checks it every 20 min, or 1/3 h.
How many times will she check it before it is cooked?
Answer:
13 times
Step-by-step explanation:
There are a total of 270 minutes in 4 1/2 hours.
270 ÷ 20 = 13.5
Though we know that 13.5 would not work out.
So she would check on it 13 times.
After the 13th time there will be 10 minutes left to cook the turkey.
The total number of times Alana will check the turkey before it sis done is 13 times.
Rate of work
The rate at which Alana is checking the turkey can be described as the work rate or the rate at which she is doing work.
Number of timesThe total number of times at which Alana will check the turkey before it is done is calculated as follows;
[tex]n = \frac{T}{R}[/tex]
where;
T is the total time = 4 1/2 h = (4 x 60) + 30 min = 270 min
R is the rate = 20 min
[tex]n = \frac{270}{20} \\\\n = 13.5 \ times\\\\n \approx 13 \ times[/tex]
There is no half checking, thus, the total number of times Alana will check the turkey before it sis done is 13 times.

What is 82+(12 3+4)-10
Answer:
82 + (12 + 3 + 4) -10 = 91
82 + (12 times 3 + 4) -10 = 156
82 + (12 divided by 3 + 4) -10 = 73.71
82 + (12 - (3+4)) -10 = 77
