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?
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?
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
Equation Answer:
y = -½x - 2

Answer:
x = -15GH = 6Step-by-step explanation:
The midline is half the length of the parallel base.
2(2x +36) = 3x +57
4x +72 = 3x +57 . . . . . . eliminate parentheses
x = -15 . . . . . . . . . . subtract 72+3x from both sides
Then the length of GH is ...
GH = 2x +36 = 2(-15) +36 = -30 +36
GH = 6
_____
The calculation steps are shown above. The strategy is to take advantage of the relation between the lengths of a midline and the corresponding base segment.

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
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.

Find the slope of the line passing through the points (-8, 9) and (6, 9).
Answer:
it is 0
Step-by-step explanation:
rise/run
9-9 / 6 - (-8)
0/14
0
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.Hope this helps you!

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

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

What is the value of x? (60 POINTS BRANLIEST IF RIGHT)
Enter your answer in the box.
x =
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

The triangle shown is equilateral, as all three angles are marked congruent.
This means that the sides are equal to each other.
