Graph 7x+y=10x-4.
Show your work and explain the method used to determine the graph.
The graph must pass through the y-axis at y = -4 with a positive slope of 3
Given the expression
7x+y=10x-4.Write the given equation in standard form to have:
7x+y=10x-4.
y = 10x - 7x - 4
y = 3x - 4
From the equation, the slope is 3 and the y-intercept is -4
The graph must pass through the y-axis at y = -4 with a positive slope of 3.

Byron opened a new bank account and immediately started depositing d dollars per week. He also withdrew w dollars per week to pay expenses. The total amount of money in the account, M, after n weeks is represented by the equation M = nd - nw . Which of the following is a factor of M?
A d - w
B n - w
d - n
D n - c
Answer: b i just took the test
Step-by-step explanation:
Option A is correct, d - w is a factor of M whose equation is M=nd-nw.
What is Number system?A number system is defined as a system of writing to express numbers.
Given that Byron opened a new bank account and immediately started depositing d dollars per week.
Byron also withdrew w dollars per week to pay expenses.
Byron also withdrew w dollars per week to pay expenses.
The total amount of money in the account, M, after n weeks is represented by the equation M = nd - nw .
M equal to n times of d minus n times of w.
We can factor out the common factor of n from the expression for M
M = nd - nw = n(d - w)
Therefore, n is a factor of M.
Hence, option A is correct, d - w is a factor of M whose equation is M=nd-nw.

A quadrilateral has two angles that measure 200 and 30°. The other two angles are in a
ratio of 6:7. What are the measures of those two angles?
Answer:
60 and 70°
Step-by-step explanation:
the angle sum of a quadrilateral is 360
200°+30°+6x+7x=360°
13x=130°
x=10°
1st angle: 10°×6=60°
2nd angle: 10°×7=70°

According to given,
x + (x+4) + (x+4)/2 = 6
x + (x+4) + (x + 8)/2 = 6
x + x + 4 + (x + 8)/2 = 6
[2 (2x + 4) + (x + 2)]/2 = 6
4x + 8 + x + 2 = 6 × 2
5x + 10 = 12
5x = 12 - 10
5x = 2
x = 2/5

What number makes the expressions equivalent? Enter your answer in the box. 12 (â€""1. 4m 0. 4) = m 0. 2.
The value of "m' that makes the expression equivalent is 0.2584
Given the expression 12 (–1.4m + 0.4) = m + 0.2
We need to solve for the value of m from the expression.
12 (–1.4m + 0.4) = m + 0.2Expand using the distributive law:
12(-1.4m) + 12(0.4) = m + 0.2
16.8m + 4.8 = m + 0.2
Collect the like terms:
-16.8m - m = 0.2 - 4.8
-17.8m = -4.6
m = 4.6/17.8
m = 0.2584
Hence the value of "m' that makes the expression equivalent is 0.2584

2) For which pair of triangles could either the Side Angle Side postulate (SAS) or Side Side Side postulate (SSS) be used
to prove the triangles congruent?
A) Pair A
B) Pair B
C) Pair C
D) Pair D
Answer:
1) A
2) D
Step-by-step explanation:
1) You can see that both sides are equal and they have only one angle in common
2) This one is a bit more quirky. You have to complete the angles. First, you name the two that are in front of each other because of the vertice. In that way, you can see that they have one side in common (S), then the angle which we just explained (A), and finally another side (S)

Describe how to transform the graph of f(x)=x2 to obtain the graph of the related function g(x)=−2(x+1)2+1. Then draw the graph of g(x).
Answer:
to go from y=x² which has a minimum vertex at (0,0), you must shift the vertex one unit to the left and then one unit up to get a maximum vertex at (-1,1)
you can then plot points that can be created from an x-y table; such as (1,-7), (-1,1), (2,17), (-2,-1), etc
Step-by-step explanation:
First tranfer x to 1 units left .

Please help!! markup and markdown word problems.
1. Andrew paid $10 for a burger. The burgers went on a sale and there was a discount of 20%. What was the sale price of the burgers?
2. Abby Matthews, store manager for Macy’s, does not know how to price a refrigerator that cost $900. She knows her boss wants a %140 mark up on the cost. Help Abby markup the cost of refrigerator.
Answer:
12, 1260
Step-by-step explanation:
Andrew paid $10 for a burger. The burger had a discount of 20%. This means that the $10 is 80% of the original price.
100% - 80% = 20%
To find the original price, you can multiply by 120%
10 * 120% = 12
Abby Matthews needs to mark up a refrigerator that costs $900 to 140% of the original price. To do this, you can directly multiply.
900 * 140% = 1260

Answer:
a) 4x -3y ≥ -24
b) 2x +3y ≥ -12
c) 4x -3y ≤ 12
d) 2x +3y ≤ 24
Step-by-step explanation:
All of the given points are on the axes, so it is useful to know the intercept form of the equation for a line is ...
x/a +y/b = 1 . . . . . . where a is the x-intercept and b is the y-intercept.
a)The boundary line for the first side is ...
x/-6 +y/8 = 1
4x -3y = -24 . . . . . . multiply by -24 to put in standard form
The graph shows the quadrilateral is to the right of this line, so its inequality is ...
4x -3y ≥ -24
__
b)The boundary line for side 2 has equation ...
x/-6 +y/-4 = 1
2x +3y = -12 . . . . . multiply by -12
The quadrilateral is to the right of this line, as well, so its inequality is ...
2x +3y ≥ -12
__
c)We can see from the graph that the x-intercept of the boundary line for side 3 is x=3. The equation for that boundary line is ...
x/3 +y/-4 = 1
4x -3y = 12
The quadrilateral is to the left of this line, so its inequality is ...
4x -3y ≤ 12
__
d)Apparently, side 4 is intended to use points already given. We assume it passes through (6, 4) and (0, 8). This boundary is parallel to side 2, so will have the same equation, but with a different constant.
2x +3y = 2(0) +3(8) = 24
The quadrilateral is to the left of this line, so its inequality is ...
2x +3y ≤ 24
__
The second attachment shows a graph of the four inequalities with their shading.
_____
Additional comment
All of the inequalities are written in standard form, so the x-coefficient is positive for all of them. The direction of the inequality symbol can be chosen to select values of x that are greater than or less than those on the boundary line. If the shading is to be to the right, then larger x-values are required, and the inequality will have the form ax + by ≥ c (a > 0). If shading is to the left, then smaller x-values are required, and the inequality symbol points in the other direction.

Suppose that a survey contacts an SRS of 400 high school seniors and calculates the sample proportion, , in this sample who have vaped in the past year.
