If the discriminant of an equation is zero, which of the following is true of the
equation?
A. It has one real solution.
B. It has two real solutions.
C. It has two complex solutions.
D. It has one complex solution.
Answer: A is the answer
Step-by-step explanation:
I just took the test!!
It has one real solution if the discriminant of an equation is zero, option (A) is correct.
What is a quadratic equation ?Any equation of the form [tex]\rm ax^2+bx+c=0[/tex] where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.
As we know, the formula for the roots of the quadratic equation is given by:
[tex]\rm x = \dfrac{-b \pm\sqrt{b^2-4ac}}{2a}[/tex]
Here:
Discriminant D:
[tex]\rm D =\sqrt{b^2-4ac}[/tex]
D = 0
[tex]\rm x = \dfrac{-b \pm0}{2a}[/tex]
x = -b/2a (one real solution)
Thus, it has one real solution if the discriminant of an equation is zero, option (A) is correct.

Step-by-step explanation:
four times a number increased by one is between a negative seven and thirteen. Find all numbers.
Answer:
Step-by-step explanation:
Let the number be x.
four times the number:
4x
If the exprression is increased by 1, it will become:
4x+1
If the value is between -7 and 13, the value of x will be within the range [-6, 12]
Equating the resulting expression to each end point.
At end point of -6
4x+1 = -6
4x = -6-1
4x = -7
x = -7/4
At the end point of 12:
4x+1 = 12
4x = 12-1
4x = 11
x = 11/4
Hence all the numbers will be within the range [-7/4, 11/4] or -7/4≤x≤11/4

PQ = 3x + 14 and QR = 7x - 10; Find x.
Answer
3x+14=7x-10
14+10=7x-3x
24=4x
6=x
Answer:
6
Step-by-step explanation:
3x+14=7x-10
14+10=7x-3x
24=4x
6=x
please follow me...The value of x in the expression is 6.
To obtain the value of x, we equate both PQ and QR
PQ = 3x + 14
PQ = 3x + 14 QR = 7x - 10
PQ = QR
(3x + 14) = (7x - 10)
3x + 14 = 7x - 10
Collect like terms
3x - 7x = - 10 - 14
-4x = - 24
Divide both sides by - 4
x = - 24 / -4
x = 6
Hence, the value of x = 6

Tamar used the algebraic method to convert the repeating decimal number to 2.45 to a fraction. Her first two steps are shown below. Step 1: x=2.45. Step 2: 100x=245.45. What should be Tamar’s next step
Answer:
see explanation
Step-by-step explanation:
Given the 2 equations
x = 2.4545... → (1)
100x = 245.4545... → (2)
Subtract (1) from (2) eliminating the repeating decimal
99x = 243 ( divide both sides by 99 )
x = [tex]\frac{243}{99}[/tex]

Answer:
Daniel has 6,174 pokemon cards:)
We know this because 18 x 343 is 6,174.
(Hope this helps)
Ava has a total of 116 cards ALL together because 18p+98c
So if we want to figure out how many cards Daniel has, you will do 343×18.
So that equals 6174, and if you want to divide it to be sure, 6174÷343 is 18.
So Daniel has 6174 cards, 343 times the amount of cards Ava has.

What is Collinear lines?Three or more points are said to be collinear if they lie on a single straight line. A line on which points lie, especially if it is related to a geometric figure such as a triangle, is sometimes called an axis. Two points are trivially collinear since two points determine a line.
So, using the concept of collinear line and translation we have
A translation is a type of transformation that moves each point in a figure the same distance in the same direction.
So, the line is congruent.

A catering business specializes in catering wedding receptions. They charge $400 for setting up the buffet and an additional $7.50 per guest. Mr. and Mrs. Smith want to spend no more than $1600 on the catering. Write and solve an inequality to determine the number of guests that can be invited to the reception.
Answer:
x<=160Step-by-step explanation:
Step one:
given data
Charges= $400
Additional charges= $7.5 per guest
let the number of guests be x
let the total cost be y
the model for the situation is given as
y=mx+C
Step two:
given that y=1600
we can solve for x as
1600=7.5x+400
1600-400=7.5x
1200=7.5x
divide both sides by 7.5 we have
x=1200/7.5
x=160
Therefore the expected guest should not be more than 160
x<=160
