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

Answers

Answer:

31

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]

Ryan has a basket of 20 blue marbles and 15 red marbles. What is the
probability that the next marble he randomly chooses will be blue?

Answers

Answer:

Probability that he chooses blue next is 4/7.

Step-by-step explanation:

In total, there are 35 marbles, since 20 + 15 = 35

There are 20 blue marbles out of the 35 marbles, so that's 20/35.

-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

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

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.
