Solve for x given the point (x,9) is a point on the line y = 3x + 7.
Answers
Answer:
0.67 = x
Step-by-step explanation:
to solve the value of x we need to : (x,9)
y = 3x + 7
9 = 3x + 7
9 - 7 = 3x
2 = 3x
2/3 = x
0.67 = x
From the given point (x , 9) let's plug the value of its y - coordinate of into Equation - y = 3x + 7 and solve for x :
[tex]9 = 3x + 7[/tex][tex]2 = 3x[/tex][tex]x = \dfrac{2}{3} [/tex]hence, value of x = 2/3

Find the slope and use the point to write an equation of the line in point slope form.
Answers
Answer:
y + 1 = [tex]\frac{1}{2}[/tex] (x + 2)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b ) a point on the line
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 2, - 1) and (x₂, y₂ ) = (0, 0) ← 2 points on the line
m = [tex]\frac{0-(-1)}{0-(-2)}[/tex] = [tex]\frac{0+1}{0+2}[/tex] = [tex]\frac{1}{2}[/tex]
Using (a, b ) = (- 2, - 1 ) , then
y - (- 1) = [tex]\frac{1}{2}[/tex] (x - ( - 2) ) , that is
y + 1 = [tex]\frac{1}{2}[/tex] (x + 2) ← in point- slope form
commission expense is budgeted to be $16,000 at a planned sales level of 4,000 units. if only 2,900 units are sold, how much commission expense will appear on the flexible budget, and is the activity variance favorable or unfavorable?
Answers
The amount of commission expense that will appear on the flexible budget if 2900 units were sold is; $11600
The activity variance is favourable.
According to the question;
The budgeted commission expenses is to be $16,000 at a planned sales level of 4,000 units.However, only 2900 units are sold.To solve this;
We must be aware that the commission expense is directly proportional to the number of units sold.
In essence;
$16,000 is expected at 4,000 units of sale.Therefore, $x is expected at 2,900 units of sale.By cross product;
x = (2900 × 16000)/4000x = $11,600Ultimately, the activity variance is favourable bas less commission expense is recorded for less sale.

2. Odd
3. Odd
4. Even
Step-by-step explanation:
Graphically, an equation is even if it is symmetrical across the y-axis. An equation is odd if it is symmetrical after folded over y and x. An equation is neither if it fulfills neither requirement.
Algebraically, an equation is even is f(x) = f(-x), and an equation is odd if f(-x) = -f(x).

2y - 3x = 7
Answers
y=3/2x + 7/2
OR
y=3/2x + 3.5
first, write the equation: 2y-3x=7
When solving for y, you want to get the y by itself on one side of the equation. Start by adding 3x to both sides. it should look like:
2y = 3x + 7
Next, divide both sides by 2 to get the y by itself. now you have:
y= 3/2x + 7/2
there you have it!! however, if you want the y intercept (7/2) in decimal form, then it’s:
y=3/2x + 3.5

Step-by-step explanation:
15 is not a fraction as is you can put any number over a one and that whole number immediately becomes a fraction:
[tex]\frac{7}{1} or \frac{43}{1} or \frac{987}{1} or \frac{1}{1} or \frac{15}{1}[/tex]
15/1 is your fraction so 15/1 divided into 15 equals 1

Answers
By transformation rules, the points A₁(x, y) = (5, - 4) and A₂(x, y) = (2, - 7) are images of point A(x, y) = (2, - 3)
How to obtain the image of a point by a vector
In this problem we must determine two images associated to a given point and that are result of an transformation rule known as a translation. This transformation rule is described below:
A'(x, y) = A(x, y) + T(x, y)
Where:
A(x, y) - Original point.A'(x, y) - Image of the point.T(x, y) - Translation vector.First, write the coordinates of the original point:
A(x, y) = (2, - 3)
Second, find the images of the original point by transformation rule:
A₁(x, y) = (2, - 3) + (3, - 1)
A₁(x, y) = (5, - 4)
A₂(x, y) = (2, - 3) + (0, - 4)
A₂(x, y) = (2, - 7)
