Use the discriminant to describe the number of solutions of the equation 2x^2+5x−12=0
Multiple choice question.
A)
The discriminant is 121, and the equation has two real, rational roots.
B)
The discriminant is 121, and the equation has one real, rational root.
C)
The discriminant is –71, and the equation has two real, irrational roots.
D)
The discriminant is –71, and the equation has two complex roots.
Answer:
a = 2
b = 5
c = -12
The discriminant is sqr root (b^2 - 4*a*c)
= sqr root (25 -4 * 2 * -12)
= sqr root (25 + 96)
= sqr root (121)
Answer is A)

Jack has a points card for a movie theater. He receives 55 rewards points just for signing up. He earns 12.5 points for each visit to the movie theater. He needs at least 205 points for a free movie ticket. Write and solve an inequality which can be used to determine vv, the number of visits Jack can make to earn his first free movie ticket.
Answer: See explanation
Step-by-step explanation:
Since Jack receives 55 rewards points just for signing up and earns 12.5 points for each visit to the movie theater and needs at least 205 points for a free movie ticket.
The inequality which can be used to determine v, the number of visits Jack can make to earn his first free movie ticket will be:
55 + 12.5v ≥ 205
12.5v ≥ 205 - 55
12.5v ≥ 150
v ≥ 150/12.5
v ≥ 12
The number of visits that Jack can make to earn his first free movie ticket will be at least 12 visits
List the sides from LEAST to GREATEST.

The common difference is positive because the arithmetic sequence is increasing.
Answer:
B. arithmetic sequence; 9
Step-by-step explanation:
An arithmetic sequence is a sequence where there is a common difference between each term. A common difference is a number that is added to the previous term to get the current term. For a sequence to be considered arithmetic this common difference must remain constant. This sequence is arithmetic because each time 9 is added to the previous term to get the next one. So the common difference is 9 and B is correct.

The surface area of the triangular prism pictured below is 204 square centimeters. What is the height of the prism?
Answer:
height x=21.5cm
Step-by-step explanation:
Surface area = 2+ area of triangles + area of the 3 rectangles
SA = 204
204 = 4*3 + x*5 + 5*4 + x*3
204 = 12 +20 +8x
204 -12-20 = 8x
172/8 = x
21.5 = x

scale A is the image figure of scale B
Answer:
x=20
Step-by-step explanation:
12.5/1.25=10
This means that to get from Figure B to A, you would need to divide by 1.25
So to get from Figure A to B, you would have to multiply by 1.25
16*1.25=20

Jeremy was 45 inches tall when he started kindergarten. He grew an average of 2.5
inches every year. Jeremy is now 62.5 inches tall.
Which equation can be used to find how many years ago Jeremy started kindergarten,
and how many years ago was it?
Answer:
subtraction
Step-by-step explanation:
its subtraction because if you do 62.5-2.5 it = 60 and then 60-2.5=57.5 57.5-2.5=55 55-2.5=52.5 52.5-2.5=50 50-2.5= 47.5 47.5-2.5 = 45 s so it was 7 or 8 years ago idk count them see how many times i did it

It's not a linear equation, but its grapg is a straight line.
It is a linear equation, and its graph is a straight line.
It's not a linear equation and its graph is not a straight line.
it's a linear equation, but the graph is not a straight line
Answer:
The given line y = -2x +30 is a straight line as it is written in the
form y = mx + b.
The graph of the line y = -2x +30 is also straight and attached below.
Step-by-step explanation:
Given the equation
y = -2x +30
We know that the slope-intercept form of the line equation is
[tex]y=mx+b[/tex]
Where m is the slope and b is the y-intercept
The graph of y=mx+b is a straight line as it is the line equation.Writing the equation in the slope-intercept form
y = -2x +30
y = mx + b
Thus,
m = -2
b = 30
Thus, the given line y = -2x +30 is a straight line as it is written in the
form y = mx + b.
The graph of the line y = -2x +30 is also straight and attached below.
