Answer:
The square root of 2 is between 1 and 2, so radical 2 is about 1.4.
Step-by-step explanation:
You can plot a 1 on the very left and a 2 on the very right of the number line.
Since there is no formal square root of 2, you have to estimate.
It has to be less than 2 because if you multiply 2 * 2 you get 4 and that's too big; we want to get 2.
It also has to be greater than 1 because 1 * 1 = 1 and that's too low.
I would estimate it to be right before the middle line.

solve the formula for y (pls give steps)
-10x +2y = 4
Answers
add 10x to both sides (we do that because it cancels the negative 10x out)
2y = 4 + 10x
divide everything by two (because we need to get y alone on one side)
y = 2 + 5x
flip the 5x and 2 (because that is the form of y intercept form)
y = 5x + 2

The scatterplot shows the number of minutes Tyler played in his last eight basketball games and the points he
scored in each game. Estimate the location of the line of best fit. About howmany points would Tyler score if he
played for 40 minutes?
Answers
The equation of the line is : Ŷ = -0.1667+0.5935X.
The estimated number of points that will be obtained if Tyler played for 40 minutes is 24 points
To obtain the location of the line of best fit, we wrote out the coordinates of the points on the graph :
(6, 10) ; (8, 18) ; (10, 17) ; (12, 20) ; (17, 21) ; (11, 23) ; (14, 25) ; (18, 30)
Using technology, we can estimate the line of best fit :
Using a linear regression solver :
Y :
6, 8, 10, 12, 17, 11, 14, 18
X:
10, 18, 17, 20, 21, 23, 25, 30
The equation of the regression line obtained is :
Ŷ = -0.1667+0.5935X
The Number of points of Tyler played for 40 minutes :
x = 40
Ŷ = -0.1667+0.5935(40)
Ŷ = 23.5733 = 24(nearest whole number).
The estimated number of points that will be obtained if Tyler played for 40 minutes is 24 points.

[tex]\\ \sf\longmapsto x=\dfrac{24}{6}[/tex]
[tex]\\ \sf\longmapsto x=4[/tex]
Step-by-step explanation:
let the length be X and breadth be 2x
p=2(l+b)
24=2(X+2x)
24=2x+4x
24=6x
24÷6=x
4=X
so,we know that
X=4 and 2x=2 X 4= 8
therefore the value of breadth or width is 8

Find WV 2X+26 2X+31
I'm not sure how to finish this problem or if I'm doing it right. Please help
Answers
Answer:
4
Step-by-step explanation:
Yes u are doing it right
So just find x first
2x + 26 + 2x +31 =13
4x + 57 = 13
4x = - 44
x = - 11
Since now u know x = - 11, and u know
WV =2X+26
So...
2x + 26
=2(-11) + 26
= - 22 + 26
= 4

which is parallel to the line y = -5/8x+6
Answers
Answer:
The answer lies in the gradient.
Step-by-step explanation:
The gradient in this equation is -5/8. If any line has the same gradient as the equation above they are parallel because they have the same slant or tilt. Gradient determines if a line is parallel between linear line graphs. If the gradient between two linear line graphs are equal that means that they are parallel.
First identify what is the gradient of a line. The gradient is usually the number that is multiplied with x. In this case (-5/8x), -5/8 is the gradient.
