Answer:
Perpendicular
Step-by-step explanation:
What I would do first is to rearrange these equations into the equation of a line formula: [tex]y=mx+c[/tex]
To do so, we isolate y:
x - y = 4 -> -y = -x+4 -> (multiply both sides by -1) y=x-4
x+y=9 -> y=-x+9
We know that in the formula y=mx + c, m stands for gradient of a line (The degree of steepness of the line), and we know that if there is no number before x it means that it is 1 or -1 (depending on the sign before x).
so that on y=x-4 the gradient is 1 and on y=-x+9 the gradient is -1.
We now can check if its parallel, perpendicular or neither with these equations:
m1 · m2 = -1 for perpendicular, m1 = m2 for parallel,(where m = gradient)
we plug the values of the two gradients into the first equation
(m1 · m2 = -1) and it fits: 1 x -1 = -1
If we plug the same values into the second equation (m1 = m2), we can check that 1 ≠ -1
In conclusion, we can check that these lines are perpendicular to each other.

Rita is making greeting cards, which she will sell by the box at an arts fair. She paid $24 for a booth at the fair, and the materials for each box of cards cost $3. She will sell the cards for $11 per box of cards. At some point, she will sell enough cards so that her sales cover her expenditures. How much will the sales and expenditures be? How many cards will that take?
Step-by-step explanation:
we need to find the number n of sold boxes, so that the income (sales) and costs (expenditures) are equal. this is called the break even point. any more boxes sold will then result in a profit, actually gaining money. and if she cannot reach that number of sold boxes, then she will make a loss.
so,
n×11 = n×3 + 24
n×8 = 24
n = 3
it will take 3 sold boxes of cards to break even.
at that point she will have spent $24 + 3×$3 = $33, and her sales will be 3×$11 = $33.

Step-by-step explanation:
(x1,y1) = (-1,-1)
(x2,y2) = (2,-2)
m = (y2 - y1)/(x2 - x1)
m = (-2 + 1)/(2 + 1)
m = -1/3

a group of 3 people are sharing chocolates each person wants 8 chocolates and each box has 6 chocolates
4 boxes of chocolates are needed by the group.
If a group of 3 people are together, needing 8 chocolates each. This means that the total number of chocolates needed is 8 × 3 = 24.
Again, we are told that each box contains 6 chocolates. This means that to get the number of boxes needed, we have to divide the total number of chocolates needed by the number of chocolates per box.
Essentially, 24/6 = 4 boxes of chocolates

Answer:
[Option 1] Wayne ascends at a faster speed
[Option 5] Wayne was deeper when he began ascending
Step-by-step explanation:
Taking out important pieces:
[] Wayne = y = 30x - 105
[] Winston = Table
[] They are going from negative to 0, so the slope is positive
Solving:
Let's fine out some points for Wayne, to make it easy, we will plug in the same x values in Winston's Table
y = 30x - 105 -> y = 30(0) - 105 -> y = -105
y = 30x - 105 -> y = 30(3) - 105 -> y = -15
So Wayne is (0, -105) & (3, -15), and from the table Winston is (0, -100) & (3, -16)
Answering:
Because at 3 seconds Winston was at -16 and Wayne was at -15, then option 1 is also correct.
Since Wayne started 5 feet deeper, option 5 is correct.
Have a nice day!

A. X=-1
B. X= 1

Step-by-step explanation:
Let the number = x

Add 5: 4x + 5
=
3x + 6
Now equate the two parts.
4x + 5 = 3x + 6 Subtract 5 from both sides
4x + 5 - 5 = 3x + 6 - 5 Combine
4x = 3x + 1 Subtract 3x from both sides
4x-3x=3x -3x + 1 Combine
x = 1

A rectangle has a width of 1/5 and a length of 10x-15
Write the perimeter of this rectangle in simple form
Write the expression that represents the are of the rectangle
and
What would be the perimeter if x=10 Show your work and circle your final answer
They have three different section so answer each section
Answer:
Step-by-step explanation:
Perimeter:
Perimeter = 2*(length +width}
[tex]=2*(10x-15+\dfrac{1}{5})\\\\\\=2*(10x - \dfrac{15*5}{1*5}+\dfrac{1}{5})\\\\\\=2*(10x -\dfrac{75}{5}+\dfrac{1}{5})\\\\\\=2*(10x -\dfrac{74}{5})\\\\= 20x - \dfrac{148}{5}[/tex]
Area:
Area = length * width
[tex]= \dfrac{1}{5}*(10x-15)\\\\\\=\dfrac{1}{5}*10x - \dfrac{1}{5}*15\\\\\\=2x - 3[/tex]
x = 10
Perimeter = 20*10 - (148/5)
[tex]=200- \dfrac{148}{5}\\\\= \dfrac{200*5}{1*5}-\dfrac{148}{5}\\\\=\dfrac{1000-148}{5}\\\\=\dfrac{852}{5}\\\\=170.4[/tex]
Answer:
1.)-29 3/5 + 20x 2.)2x-15 3.)85 1/5
Step-by-step explanation:
you have 4 sides of a rectangle and to solve for the perimeter of a rectangle you have to add up all four sides. you have the width of the rectangle and the length. SO add them up once then multiply it by two.
If your trying to find the area you multiply L*W=A^2 so just multiply your length and width.
If the x was 10 just plug in you x and solve.
It gets tricky with the variable x and I'm guessing that's where you getting caught up.
for the first one you would have 1/5 + 10x - 15 then you want to multiply it by two getting -29 3/5 + 20x that's the equation you'd use for the first expression. for the second one you want to find the area so 1/5 * 10x-15 you'd then want to simplify it which would be 2x-15
and for the third one. You have the length and the width so the perimeter is calculated by (1/5 + 10(10)-15)2 1/5+100-15 and you get 85 1/5
Sorry if this is wrong.
Triangle PQR is similar to triangle STU. Find the measure of side TU. Figures are not drawn to scale.
Step-by-step explanation:
when 2 triangles are similar, it means that both have the same angles. and that then all the corresponding side lengths relate to each other by the same multiplication factor.
PQ and ST are corresponding sides.
the length of ST (4) is the length of PQ (16) multiplied by 1/4.
16 × 1/4 = 4.
the same factor (1/4) also applies to the other sides.
and therefore,
TU = QR × 1/4 = 19.2 × 1/4 = 19.2/4 = 4.8

Step-by-step explanation:
Before I discuss how to graph both equations, I believe that it is essential to understand the variables and constant related to linear equations.
The slope-intercept form is: y = mx + b, where:
m = slope (which tells you the steepness of the line).
b = y-intercept: this is the point on the graph where it crosses the y-axis. Its coordinates is always formatted as, (0, b). The b is the y-coordinate of the y-intercept that you use for the equation.
The standard form of linear equations is: Ax + By = C, where:
A, B, C are integers (whole numbers, and cannot be in fraction or decimal forms). A and B ≠ 0, and A must be a positive integer.
Now that I have defined what the slope-intercept and standard form of linear equations are, we can proceed with working on graphing both equations.
7. y = -6x - 4In this equation, the slope (m) = -6, and the y-intercept (b) = -4. As an ordered pair, the y-intercept is (0, -4). In order to graph this equation, start by plotting the y-intercept on the graph. Then, use the slope (rise over run) to plot other points on the graph (6 units down, 1 unit run). Your next point should occur at (1, -10).
You could simply connect these two points and draw a line, or plot another point on the graph using the slope technique mentioned in this post.
8. 3x - 4y = 12This equation is in standard form, Ax + By = C. It is easier to graph a linear equation when it is in its slope-intercept form, y = mx + b.
In order to transform this equation into its slope-intercept form, start by subtracting 3x from both sides of the equation:
3x - 4y = 12
3x - 3x - 4y = - 3x + 12
-4y = -3x + 12
Next, divide both sides by -4 to isolate y:
[tex]\frac{-4y}{-4} = \frac{-3x + 12}{-4}[/tex]
y = ¾x - 3 ⇒ This is the slope-intercept form where the slope, m = ¾, and the y-intercept is b = -3.
Similar to how we graphed the equation from question 7, start by plotting the y-intercept, (0, -3). Then, use the slope of the equation, m = ¾ (3 units rise, 4 units run) to plot the next point. The next point should occur at (0, 4).
Attached are the graphed equations.
The function rulе fоr {{0, 14), (1, 12), (2, 10), (3, 8), (4, 6)} is:
y=-2х + 6.
y=-2х + 14.
y=-2х +2.
None of these choices are correct.

A line with a slope of –4 passes through the points (9,w) and (8,9). What is the value of w?
Answer:
