What is the slope of the line?

Answers

Step-by-step explanation:

A line is intersecting Point (3,4) and (-1,-3)

m = (y2 - y1)/(x2 - x1)

m = (-3 - 4/(-1 - 3)

m = -7/-4

m = 7/4

Slope = 7/4

Answers

Answer:

4x + 3y = 1

Step-by-step explanation:

(1, -1)

3x - 4y = 20 ---> 4y = 3x - 20 ---> y = 3/4 x - 5

so slope is 3/4

and perpendicular slope is m * 3/4 = -1

m = -4/3

line equation is y - y1 = m (x - x1)

y - (-1) = -4/3 ( x - 1)

y + 1 = -4/3 (x - 1)

3y + 3 = -4x + 4

4x + 3y = 1

A middle school art teacher wishes to teach his class about costume design. He divides the class into three groups at random, each of which is tasked with designing a mascot costume for a fictional sports team, with a prize going to the best design. The student teams then spend a week designing and building their mascot costumes. Several weeks later, the teacher is surprised to discover that a rivalry has formed between the various teams, who have formed cliques even outside the classroom. What explains the reason that this rivalry has formed

Answers

The reason that this rivalry has formed is that a common goal has been set for a greater number of groups than the one that could obtain a positive result, generating a competition between these that implies a constant desire to overcome the other groups.

Thus, the existence of these common objectives makes competition take place, and generates tensions between the groups.

Write and solve the equation:
a number is less than one fourth the sum of three times the number and four.

Answers

Answer:

The number is less than 4.

Explanation:

If we write the inequality out, we get this:

x<14(3x+4)

Now we just need to solve for x. Multiplying both sides by 4 yields:

4x<3x+4

Subtract 3x from both sides:

x<4

So any number less than 4 will work!

Step-by-step explanation:

Matthew wants to sell laptops and smartphones. He wants to sell at least 12 devices and earn at least $4500. L+S≥ 12 represents the number of laptops, L and smartphones, S Matthew should sell to achieve his goal of selling at least 12 devices. 425L+125S≥4500 represents the number of laptops and smartphones he can sell to earn at least $4500 Based on the inequalities from the scenario above, what is the cost of a laptop and the cost of a smartphone?

Answers

The cost of a laptop and the cost of a smartphone are;

Cost of laptop = $4250

Cost of laptop = $4250Cost of smartphone = $250

He wants to sell at least 12 devices.

Thus;

L + S ≥ 12 - - (eq 1)

Where:

L is number of laptops

S is number of smartphones.

If he achieves his goal of at least 12 devices, he will earn at least $4500. Thus;

425L + 125S ≥ 4500 - - - (eq 2)

Multiply eq 1 by 125 and multiply eq 2 by 1 to get;

125L + 125S = 1500 - - - (eq 3)

425L + 125S = 4500 - - - (eq 4)

Subtract eq 3 from eq 4 to get;

300L = 3000

L = 3000/300

L = 10

Thus;

10 + S = 12

S = 12 - 10

S = 2

From the given inequalities, 425L represents the cost of a laptop. Thus;

Cost of laptop = 425 × 10

Cost of laptop = $4250

Cost of smartphone = 125 × 2

Cost of smartphone = $250

What is the function rule for the line?

Answers

Answer:

f(x) = (2/3)x-2

Step-by-step explanation:

The slope is positive. We can calculate it by taking any two points on the line and finding the Rise (change in y) divided by the corresponding Run (the change in x). I'll pick points (-3,-4) and (3,0) [mostly becasue it is easy to see whole numbers for both x and y at these points].

Going from (-3,-4) to (3,0):

Rise = (0-(-4)) = 4

Run = (3-(-3)) = 6

Rise/Run, or slope, = 4/6 or 2/3.

Put this into the standrad form for a straight line: y=mx+b, we get:

y = (2/3)x + b.

b is the y-intercept, the value of y when x is zero. We can find that on the graph. When x = 0, y = -2. So b is -2.

y = (2/3)x - 2

x + 2y = -4 in graph

What is the value of x? (60 POINTS BRANLIEST IF RIGHT)

Enter your answer in the box.

x =

Answers

Answer:

Since all three of the interior angles are the same degree, the three sides must be the same length. So, 3x - 5, 4x - 30, and 2x + 20 must be equal.

To solve for x, you can just set one of the sides equal to another one of the sides. I will do 3x - 5 and 4x - 30.

3x - 5=4x - 30

Add 5 to both sides.

3x = 4x - 25

Subtract 4x from both sides.

-x = -25

Divide both sides by -1.

x=25

This means that the sides are equal to each other.

Write a linear function f with f(0) =3 and f(-6) =3.
f (x) =

Answers

Answer:

f(x) = 3

Step-by-step explanation:

f(0) = 3 means you have the ordered pair (0, 3)

f(-6) = 3 means you have the ordered pair (-6, 3)

Form this point, you can look at the ordered pair and see that the y values are the same but the x values are difference. This is a line with slope = 0 and the graph of the line is horizonal .

But if you need more explanation see below.

1. Find the slope using the ordered pair above

slope = (3 - 3)/ (-6 - 0) = 0/-6 = 0 so the slope = 0

2. Find the y intercept (b) by using the slope intercept formula: y = mx + b

y = mx + b

3 = 0(0) + b

3 = b

equation of the line: y = 0x + 3; y = 3 remember y = f(x)

so f(x) = 3

Hello there!

Use the slope formula:

m=[tex]\frac{y2-y1}{x2-x1}[/tex]

Now, plug in all the values:

[tex]\frac{9-9}{6-(-8)} \\\frac{0}{6+8} \\0[/tex]

The slope is 0. Why?

If we are given 2 points and their y-coordinates are the same, then the line is a horizontal line. Its rise is zero.

Another formula for Slope is Rise/Run. If the rise (the amount of units we move up) is 0, then the slope is 0.

Therefore, the slope is 0.

if the temperature was 0 C and then there was a temperature change of 5+ C what temperature change would return the temperature to 0 C?

Answers

Using simple mathematical operations we can say that the change of -5°C would bring back the temperature to 0°C.

What do we mean by mathematical operations?An operation, in mathematics, is a mathematical function that transforms zero or more input values into a precisely defined output value.The arity of the operation is influenced by the number of operands.A mathematical action is called an operation.Mathematical operations include addition, subtraction, multiplication, division, and finding the root.

So, the change that will bring back the temperature to 0°C:

The temperature was at 0°C.After the change, the temperature was 5°C.So, the change was 0°C+5°C = 5°C (+5°C).

Now, to get back to 0°C:

5°C - 5°C = 0°C

Therefore, using simple mathematical operations we can say that the change of -5°C would bring back the temperature to 0°C.

Step-by-step explanation:

Sides -

As measure of opposite sides of a parrelelogram are equal -

4a + 10 = 6a

10 = 6a - 4a

10 = 2a

10/2 = a

5 = a

Therefore - WZ = 4 x 5 + 10 = 30

And as, WZ = XY (opposite sides are equal), XY = 30

I don't know how to find the length of ZY and WX

Angles -

As adjecent angles of a parrelelogram are sumplimetory, (b+15) + 2b = 180

So,

B+15 + 2b = 180

3b +15 = 180

3b = 180 - 15

3b = 165

B = 165 / 3

B = 55

Therefore, angle X = 55 + 15 = 70 (b+15)

And angle Y = 2 x 55 = 110 (2b)

And, angle W = angle Y (opposite angles of a parrelelogram are equal)

So, angle W = 110

And, angle Z = angle X (opposite angles of a parrelelogram are equal)

So, angle Z = 70
