Sherry uses the steps below to solve the equation x + (negative 8) = 3 x + 6.

Step 1 Add 1 negative x-tile to both sides and create zero pairs
Step 2 Add 8 positive unit tiles to both sides and create zero pairs.
Step 3 Divide the 14 unit tiles evenly among the 2 x-tiles.
Step 4 The solution is x = 7

What is Sherry’s error?
In step 1, she should have added 3 negative x-tiles to both sides.
In step 2, she should have added 6 negative unit tiles to both sides.
In step 3, she did not divide the tiles evenly.
In step 4, she should have found the solution x = negative 1.

Answer:

The equation for line k is [tex]y = -2x + 6[/tex]

Step-by-step explanation:

The equation of a line has the following format:

[tex]y = mx + b[/tex]

In which m is the slope.

When two lines are perpendicular, the multiplication of their slopes is -1.

The equation for line j can be written as y =1/2x-1

Since k is perpendicular to j, and the slope of j is 1/2, the slope of k is:

[tex]\frac{1}{2}m = -1[/tex]

[tex]m = -2[/tex]

So

[tex]y = -2x + b[/tex]

It passes through the point (6,-6).

This means that when [tex]x = 6, y = -6[/tex]. So

[tex]y = -2x + b[/tex]

[tex]-6 = -2(6) + b[/tex]

[tex]b = 6[/tex]

So

[tex]y = -2x + 6[/tex]

Answer:

Step-by-step explanation:

THe first one is infinitely many solutions , you see y-2x=7 is the same as y=2x+7 which means they will intersect on every point

y-2x=7, simply add 2x to both sides

y=2x+7

The second one has no solution, if you solve for y on each side, you will find that the lines are parallel (slope is the same) and will never intersect.

THe third one has one solution

Answer:

15 cm

Step-by-step explanation:

The perimeter of a rectangle is 2(L + W), where L is length of the rectangle and W is the width.

If we plug in 10 for W, we get this:

2L + 2(10) = 50 <-- the perimeter

2L + 20 = 50

2L = 30

L = 15

Answer:

The other endpoint is (-1, 1).

Step-by-step explanation:

What we know is one endpoint is at (5, -9). The midpoint is at (2, -4).

So, to find the slope, find (yB - yA)/(xB - xA)

(-4 -(-9))/(2 - 5)

(-4 + 9)/(2 - 5)

5/-3

The slope is -5/3.

Knowing this, subtract 3 from the midpoint's x, and add 5 to the midpoint's y.

((2 - 3), (-4 + 5))

The other endpoint is at (-1, 1).

Continuity correction is a theory in which addition or subtraction is made with the discrete variables. Continuity variable helps to find the single probabilities of the function and it removes some errors that are found in the modelling of discrete distribution.

Answer: 37 times 3 is 111. So there are 111 junior at that school.

1/3 times the # = the answer.

Given:

Consider the given function is [tex]f(x)=-(x+1)(x-3)(x+2)[/tex].

To find:

The remaining zero and y-coordinate of y-intercept.

Solution:

We have,

[tex]f(x)=-(x+1)(x-3)(x+2)[/tex]

For zeros, [tex]f(x)=0[/tex].

[tex]-(x+1)(x-3)(x+2)=0[/tex]

[tex](x+1)(x-3)(x+2)=0[/tex]

[tex](x+1)=0,(x-3)=0,(x+2)=0[/tex]

[tex]x=-1,x=3,x=-2[/tex]

So, three zeros of given function are -1, 3 and -2.

Putting x=0 in the given function, we get

[tex]f(0)=-(0+1)(0-3)(0+2)[/tex]

[tex]f(0)=-(1)(-3)(2)[/tex]

[tex]f(0)=-(-6)[/tex]

[tex]f(0)=6[/tex]

So, the y-coordinate of y-intercept of the given function is 6. It means the y-intercept is at point (0,6).

Therefore, the zeros of the function [tex]f(x)=-(x+1)(x-3)(x+2)[/tex] are –1, 3, and -2 and the y-intercept of the function is located at (0,6).

Answer:

$21.15

Step-by-step explanation:

6 x 1.15 = 6.9 (because we're working with money, we'll add a zero at the end for the ones place) = 6.90

15/5 = 3 then 3 x 4.75= 14.25

14.25 + 6.90 = 21.15

Hope this helped <3

Answer:

$21.15

Step-by-step explanation:

Total Folder Amount: $1.15 • 6 = $6.90

Total Pen Amount: $4.75 • 3* = $14.25

*She bought 15 pens. The pens were 5 pens for $4.75. 15÷5=3*

$14.25 + $6.90 = $21.15

Answer:

The equation of the line that passes through the points (7,-8) and (2, -8) is [tex]\mathbf{y=-8}[/tex]

Step-by-step explanation:

We need to write the equation of the line that passes through the points (7,-8) and (2, -8).

We need to write answer in fully reduced point-slope form, unless it is a vertical or horizontal  line.

The general equation of point-slope form is: [tex]y-y_1=m(x-x_1)[/tex]

where m is slope of the line.

To find the slope, we can use formula: [tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]

We have [tex]x_1=7,y_1=-8,x_2=2, y_2=-8[/tex]

Putting values and finding slope:

[tex]Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{-8-(-8)}{2-7}\\Slope=\frac{-8+8}{-5}\\Slope=\frac{0}{-5}\\Slope=0[/tex]

So, we find the slope : m = 0

Now, using the point (7,-8) and slope m =0, the required equation is:

[tex]y-y_1=m(x-x_1)\\y-(-8)=0(x-7)\\y+8=0\\y=-8[/tex]

So, the equation of the line that passes through the points (7,-8) and (2, -8) is [tex]\mathbf{y=-8}[/tex]
