Evaluate the equation y=2x2 - 2x + 7 for x=-3

Answers

Answer:

Step-by-step explanation:

y=2x^2 - 2x + 7

Let x= -3

y=2(-3)^2 - 2(-3) + 7

=2 (9) +6 +7

= 18 +6+7

= 31

Problem:

Evaluate the equation:

[tex]\tt{y = 2 {x}^{2} } - 2x + 7 \: ,when \: x \: = \: - 3[/tex]

Let's try!

[tex]\quad \quad \quad \quad \tt{y = 2 {x}^{2} } - 2x + 7[/tex]

[tex]\quad \quad \quad \quad \tt{y = 2 {( - 3)}^{2} } - 2( - 3)+ 7[/tex]

[tex]\quad \quad \quad \quad \tt{y = 2(9) +6 + 7}[/tex]

[tex]\quad \quad \quad \quad \tt{y = 18 +6 + 7}[/tex]

[tex]\quad \quad \quad \quad \tt{y = 24 + 7}[/tex]

[tex]\quad \quad \quad \quad \tt{y = 31}[/tex]

Hence, the answer is:

[tex]\quad \quad \quad \quad \boxed{\tt{\color{green}y = 31}}[/tex]

A number is divisible by 4 when the last two digits are a multiple of 4
So 04, 24, 44, 64, 84 are all valid final pairs

This is because all hundreds are divisible by 4

-6-9t+4=34 Simplify plz

Answers

Answer:

t = -4

Step-by-step explanation:

-6-9t+4=34

-9t=34+6-4

-9t=36

-t=36/9

-t = 4

t = -4

Answer:

t = -4

Step-by-step explanation:

-6-9t+4=34

Combine like terms

-9t -2 = 34

Add 2 to each side

-9t -2+2 = 34+2

-9t = 36

Divide by -9

-9t/-9 = 36/-9

t = -4

Which line is parallel with y = -3x + 10

Answers

Answer:

If a line is parallel with Another...

They will have the same Gradient or equal Gradient (m)

So for two parallel lines

m=m'

So the gradient of the second or other line would be Same

Now

y= -3x + 10

comparing with

y= mx + c

m = -3

So the other line would have the same gradient.

from the options provided in the comment section...

y= -3x + 12

Is your Most probable answer cos it has the same gradient

Based on records from the past several seasons the probability of the Madison Math Team winning a competition is p(win)-0.875
If they compete in 24 competitions, how many will they win?

Answers

Answer:

They will win 21 games

Step-by-step explanation:

Here, we want to get the number of possible wins

From the question, we have it that the probability that the team will win is 0.875

Now, out of the 24 games, we simply have to multiply their winning probability by the number of games

We have this as;

0.875 * 24 = 21

Hence, out of the 24, 21 will result in a win

How can you find the slope of a line from the coordinates of two points on the line?

Answers

By using the formula

Answer:

use the slope formula to find the slope of a line given the coordinates of two points on the line and the slope formula is m=( y2- y1)/ (x2 - x1) or the change in the y values over the change in x values.The coordinates of the point represent x1 and y1. The coordinates of the second points are x2, y2.
