Mark is solving an equation where one side is a quadratic expression and the other side is a linear expression. He
sets the expressions equal to y and graphs the equations. What is the greatest possible number of intersections for
these graphs?
none
one
two
infinitely many
Answer:
The answer would be two because one of the lines would be a parabolic line and parabolic lines only have at the most two solutions.
The greatest possible number of intersections for the graphs is two.
What is the greatest possible number of intersections of the graph?It follows from the task content that the two graphs involved are;
A linear and quadratic graph.By convention, a quadratic graph produces a parabola and a linear graph produces a straight line. On this note, it follows that the best case of intersection is when the straight line crosses over the parabola and hence leading to two points of intersection.

You roll a six-sided die. Find the probability of each of the following scenarios. (a) Rolling a 5 or a number greater than 3. (b) Rolling a number less than 5 or an even number. (c) Rolling a 2 or an odd number
Answer:
Step-by-step explanation:
a.
let A= number 5
B=number >3
P(A)=1/6 {5}
P(B)=3/6 {4,5,6}
p(A∩B)=1/6 {5}
P(AUB)=P(A)+P(B)-P(A∩B)=1/6+3/6-1/6=3/6=1/2
b.
let event C=number<5
D=even number
C=[1,2,3,4}
D={2,4,6}
C∩D={2,4}
P(C)=4/6
P(D)=3/6
P(C∩D)=2/6
P(C∪D)=P(C)+P(D)-P(C∩D)=4/6+3/6-2/6=5/6
c.
let event E=number 2
F= an odd number.
E={2}
F={1,3,5}
E∩F={}
P(E)=1/6
P(F)=3/6
P(E∩F)=0
P(E∪F)=P(E)+P(F)-P(E∩F)=1/6+3/6-0=4/6=2/3
If you count to 100 by 2, how many numbers will you say?
Answer:
If you start at 0, 51. If you start with 2, 50.
Step-by-step explanation:
The amount of numbers that will be said are simply 100/2 which is 50 since counting by two is the same as the amount of even numbers up to 100. If you start at 0, simply add an additional count, making 51.

Step-by-step explanation:
Step 1:
- 12x + 10x
Answer:
- 2x
Hope This Helps :)
Answer:
-2x
Step-by-step explanation:
Like the other problem, we want to combine our like terms(in this case, all terms with x's). In order to do this, all you have to do is ignore the x's and then add the numbers together. -12 + 10 = 2. Now that we've added them together, you can add the x back to get 2x.

Answer:
[tex]B = \frac{6D + 18 {f}^{3} }{M} [/tex]Step-by-step explanation:
[tex] - 3 {f}^{3} + \frac{1}{6} MB = D [/tex]
Multiply through by 6 to eliminate the fraction
That's
[tex] - 18 {f}^{3} + MB = 6D[/tex]
Move - 18f³ to the right side of the equation
That's
[tex]MB = 6D + 18 {f}^{3} [/tex]
Divide both sides by M to make B stand alone
That's
[tex] \frac{MB}{M} = \frac{6D + 18 {f}^{3} }{M} [/tex]
We have the final answer as
[tex]B = \frac{6D + 18 {f}^{3} }{M} [/tex]

A man drove his car a distance of 315 miles in 5 hours. If continuing at this rate is possible, he will travel miles in 9 hours. (5 points) Blank 1:
Answer:
567 miles
Step-by-step explanation:
Total distance travelled till now = 315 miles
Total time taken to cover the above distance = 5 hours.
Distance covered in each hour = [tex]\frac{315}{5} = 63[/tex]
Thus, it means in each hour it covers the distance of 63 miles.
Assuming the same speed can be continued and maintained, the total distance that can be covered in 9 hours shall be:
63 miles in each hour [tex]\times[/tex] 9 hours = 567 miles.
Answer:
567 miles

4-7x=1-6x can someone please solve and show the work :)
Answer:
x = 3
Step-by-step explanation:
Simplifying
4 + -7x = 1 + -6x
Solving
4 + -7x = 1 + -6x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '6x' to each side of the equation.
4 + -7x + 6x = 1 + -6x + 6x
Combine like terms: -7x + 6x = -1x
4 + -1x = 1 + -6x + 6x
Combine like terms: -6x + 6x = 0
4 + -1x = 1 + 0
4 + -1x = 1
Add '-4' to each side of the equation.
4 + -4 + -1x = 1 + -4
Combine like terms: 4 + -4 = 0
0 + -1x = 1 + -4
-1x = 1 + -4
Combine like terms: 1 + -4 = -3
-1x = -3
Divide each side by '-1'.
x = 3
Simplifying
x = 3

a high school football player is practicing his frield goals kicks. The equation h=-9t²+45t where t is the number of seconds gone by and h is the height of the ball in feet. how long does it take for the ball to hit the ground
h = -9t^2 + 45t
First, let's factor the equation.
h = -9t(t - 5)
Let's set both terms equal to zero.
-9t = 0
Divide both sides by -9
t = 0
t - 5 = 0
Add 5 to both sides.
t = 5
We know that it took more than 0 second sto hit the ground, therefore, the only answer that makes sense is t = 5
It took 5 seconds for the football to hit the ground.

What is the value of y in the equation 2(3y + 6 + 3) = 196 − 16?
27
29
30
33
The value of y is 27. (first option.)
isolate the variable by dividing each side by factors that don't contain the variable.
Answer:
27
Step-by-step explanation:
2(3y + 6 +3)
2(9 + 3y)
18 + 6y
18 + 6y = 196 -16
6y =196 -16 -18
6y = 162
162 divided by 6 = 27
y =27
