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

Answers

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.

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.

4-7x=1-6x can someone please solve and show the work :)

Answers

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

x = 3

Answer:

a = 1

Step-by-step explanation:

Step 1: Write equation

a - 2(4 - a) = 7a - 12

Step 2: Solve for a

Distribute -2: a - 8 + 2a = 7a - 12

Combine like terms: 3a - 8 = 7a - 12

Subtract 3a on both sides: -8 = 4a - 12

Add 12 on both sides: 4 = 4a

Divide both sides by 4: a = 1

Step 3: Check

Plug in x to verify if it's a solution.

1 - 2(4 - 1) = 7(1) - 12

1 - 2(3) = 7 - 12

1 - 6 = -5

-5 = -5

Answer:

a = 1

Step-by-step explanation:

equation given:   a - 2(4 - a) = 7a - 12

distribute and expand the equation

a - 8 + 2a = 7a - 12

combine similar terms:

a + 2a - 7a = -12 + 8

simplify:

-4a = -4

a = -4 / -4

a = 1

proof that a = 1

a - 2(4 - a) = 7a - 12

1 - 2(4 - 1) = 7(1) - 12

1 - 2(3) = 7 - 12

1 - 6 = -5

-5 = -5  therefore, the a = 1 is correct.

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 ​

Answers

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.

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]
