In the following quadratic equation identify the values of a, b, and c that you would use in the quadratic formula.
7x^2-3x+9=0
A. a=7 b=-3 c=9
B. a=9 b=7 c=-3
C. a=-7 b=3 c=-9
D. a=7 b=3 c=9
Answer:
A
Step-by-step explanation:
Let's first define what exactly the values of a, b, and c represent.
- a: this is the coefficient of the x^2 term
- b: this is the coefficient of the x term
- c: this is the constant term (no variable attached)
Our equation is: y = 7x^2 - 3x + 9.
The coefficient of x^2 is 7, so a = 7. The coefficient of x is -3, so b = -3. And finally, the constant term is 9, so c = 9.
Thus, the answer is A.
Answer:
The general quadratic equation is ax^2 + bx + c = 0
=> Here, we have: 7x^2 - 3x + 9 = 0 <=> 7x^2 + (-3)x + 9 = 0
=> a = 7, b = -3, c = 9
=> Option A is correct.
Hope this helps!

Answer:
the answer is 50in
Answer:
40 in
Step-by-step explanation:
It must be 40 inches because to get an area of 100 in 2 each side has to be 10 in therefor, if you multiply 10 by 4, you get 40

100 points!!!!! if you help me A semitruck and its load is measured to weigh 31 tons. A toll is assessed such that $0.01 is paid for every 10 pounds of weight. What is the amount of the toll this truck should pay?
Answer:
$62
Step-by-step explanation:
The total weight of the semitruck and its load is 31 tons. Let's convert this to pounds:
1 ton = 2000 lb
31 tons = 2000 * 31 = 62000 lb
We know every 10 lb will be priced at $0.01, so divide 62000 by 10 to find how many times we need to pay $0.01:
62000 ÷ 10 = 6200
Each of these 6200 times, we need to pay $0.01 so multiply these together:
6200 * 0.01 = 62
The answer is $62.
Answer:
its 62 dollars

Examine the diagram. Triangle A B C. Angle A is (3 x minus 24 degrees) and angle B is x degrees. The exterior angle to angle C is 132 degrees. What equation can be used to find the value of x? What is the measure of ∠B? m∠B= °
Answer:
Setting up the equation you would have: 132 = x + (3x-24)
Now solve for x:
132 = x + (3x-24)
Simplify:
132 = 4x -24
Add 24 to both sides:
156 = 4x
Divide both sides by 4:
x = 156/4
x = 39
Step-by-step explanation:
The measure and equation that should be used is 39 and 132 = x + (3x-24)
Calculation of the equation used:Since angle B is x degrees. The exterior angle to angle C is 132 degrees.
Here the equation that should be used is shown below.
132 = x + (3x-24)
132 = 4x -24
156 = 4x
x = 39

Your Work:
Answer: Divide both sides by 2 and apply square root (both sides).
Step-by-step explanation:
Hi, to answer this question we have to analyze the expression given:
2x²=200
A more simple way to solve the expression:
First, we have to divide each side by 2:
2x²/2=200/2
x²=100
Square root on both sides:
√x²=√100
x = -10 and 10

Answer:
Graphs A and C
Step-by-step explanation:
Line s : y = 1/3x - 3for x = 0 → y = 1/3(0) - 3 = 0 - 3 = -3then the line passes through the point (0,-3)
for x = 9 → y = 1/3(9) - 3 = 3 - 3 = 0then the line passes through the point (9,0)
and according to the picture ,only in graphs A and C the line C passes through (0,-3) and (9,0)
so the graph solution is either graph A or graph C.
2. line t : y = -x + 5
for x = 0 → y = -(0) + 5 = 0 + 5 = 5then the line passes through the point (0,5)
for x = 5 → y = -(5) + 5 = 0then the line passes through the point (5,0)
and according to the picture ,only in graphs A and C the line C passes through (0,5) and (5,0).
conclusion:
both graph A and C represent correctly show Lines s and t and the point P
Remark : if you look closely to the graphs A and C ,they are the same thing.
Answer: Graphs A and C
Step-by-step explanation:
Line s : y = 1/3x - 3
for x = 0 → y = 1/3(0) - 3 = 0 - 3 = -3
then the line passes through the point (0,-3)
for x = 9 → y = 1/3(9) - 3 = 3 - 3 = 0
then the line passes through the point (9,0)
and according to the picture ,only in graphs A and C the line C passes through (0,-3) and (9,0)
so the graph solution is either graph A or graph C.
2. line t : y = -x + 5
