Decide whether this statement is always true, never true, or sometimes true, and explain why: In a quadratic equation of the form 0 = ax2 + bx + c, there will be two real solutions if a and c are of opposite signs
Answer:
Always true
Step-by-step explanation:
Here, we want to evaluate if the given statement is true
The discriminant D can be calculated using the formula;
b^2 - 4ac
if D is greater than 0, then we will have only real roots
In a case where a and c are of opposite signs;
then -4ac will always give a positive value which can be added to b^2
This positive value will ensure that D is greater than zero and hence we can have only real roots
So this assertion is always true if a and c are of opposite signs
x-intercept (0,-7)
Y-intercept (2,0)
Are my answers right ?
Well the numbers are right, but not the order.
First the x-intercept is (-7,0) not (0,-7) ---- It's (x,y) though ---------
Second the y-intercept is (0,2) not (2,0)
You got them swapped but the numbers are correct anyway.

what is the following sum ?
solve the equation 7- 14m = 2m - 5
Answer:
m = 6/7
Step-by-step explanation:
Rearrange the equation so that like terms are on either side
7 + 5 = 2m + 14m
12 = 14m
Divide both sides by 14 so that the variable is on its own
12/14 = m
m = 6/7

When 3(2x + 5) is added to 2(2x − 4) the resulting expression is?
Answer:
10x + 7
Step-by-step explanation:
3(2x + 5) added to 2(2x - 4) is the same as 3(2x +5) + 2(2x - 4)
Remember PEMDAS
P – Parentheses (distribution)
E – Exponents
M – Multiplication
/D – Division (whichever comes first from left to right)
A – Addition
/S – Subtraction (whichever comes first from left to right)
First, we will distribute the left side.
3(2x + 5)
3 * 2x = 6x
3 * 5 = 15
Add them together to get:
6x + 15
6x + 15 + 2(2x - 4)
We must now distribute the right side.
2 * 2x = 4x
2 * -4 = -8
Add them together to get:
4x -8
We now have:
6x + 15 + 4x - 8
Let's combine like terms.
6x and 4x are like terms.
Combine: 6x + 4x = 10x
15 and -8 are like terms.
15 - 8 = 7
Now we have 10x + 7
Since 10 and 7 don't have any GCF, we have our answer.
10x + 7

The total cost in dollars to buy uniforms for the players on a volleyball team can be found using the function C equals 34.95 you +6.25 where you is the number of uniforms but if there are at least eight players but no more than 12 players on the team what is the domain you of the function for this situation
Answer:
8 ≤ u ≤ 12
Step-by-step explanation:
Given:
C = 34.95u +6.25
Where,
u = number of uniforms
what is the domain you of the function for this situation
The number of uniforms depend on the number of players
If there are at least 8 players but not more than 12 players on the volleyball team.
u ≥ 8
u ≤ 12
The domain of the function is
8 ≤ u ≤ 12

a parabolic lamp is facing due east. The bulb (located at the focus) is 8 inches away from the vertex (located at the origin). the lamp has a diameter of 20 inches. Which is the depth of the dish?
9514 1404 393
Answer:
3 1/8 inches
Step-by-step explanation:
For focus-vertex distance p, the equation of the parabola can be written ...
y = x^2/(4p)
Here, we have p=8. We want to find the value of y when x=10 (the radius of the dish). That is ...
y = (10^2)/(4·8) = 100/32 = 3 1/8
The dish is 3 1/8 inches deep.

A. Yes, because every x- and y-value is positive.
OB. No, because two points with the same x-value have different ya
values,
OC. Yes, because the number of x-values is the same as the number o
y values
D. No, because two points with the same y-value have different x-
values
Answer:
B
Step-by-step explanation:
Eveey input must have exactly one output, x is always the input and y is the output and there are two y outputs on one x input so it is not a function.

Sharon drove 270 miles in 4.5 hours. If she drove at a constant rate, how fast was Sharon driving?
Answer:
Sharon was driving 60 miles per hour.
Step-by-step explanation:
To solve this you must divide both the amount of miles (270) and the amount of hours (4.5) by the amount of hours so that way you can see how many miles per hour you are going.
4.5 / 4.5 = 1
270 / 4.5 = 60
This means that Sharon was driving 60 miles per hour.
