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

Which line is parallel with y = -3x + 10
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
5(2)^x=40 what is the value of x
Answer:
x=3
Step-by-step explanation:
5(2)^x=40
Divide each side by 5
5 /5 *(2)^x=40/5
2^x = 8
Rewriting 8 as 2^3
2^x = 2^3
The bases are the same so the exponents are the same
x=3
Answer:
x = log(40)
Step-by-step explanation:
[tex]5(2)^{x} =40[/tex]
[tex]10^{x} =40[/tex]
[tex]10^{x} =40[/tex]
x = log(40)

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

-6-9t+4=34 Simplify plz
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

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?
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.
20/35 simplified is 4/7.
