plz help i give brainliest and points
Answer:
b) 1 / 4
c) -3
Step-by-step explanation:
b) line passing through points (0,-1) (4,0)
slope = (y2 - y1) / (x2 - x1)
= (0 - (-1) ) / (4 - 0)
= 1 / 4
c) line passing through points (-1,2) (0, -1)
slope = (y2 - y1) / (x2 - x1)
= (-1 - 2) / (0 - (-1) )
= -3 / 1
= -3
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.

Answer:
x = -10
Step-by-step explanation:
Explanation:Essentially, the function notation, "g(x)" is the same as y.
Given g(x) = 2(x - 5), we could determine x for g(x) = - 30 by substituting -30 as the value of g(x) into the function:
g(x) = 2(x - 5)
-30 = 2(x - 5)
Distribute 2 into the parenthesis on the right-hand side of the equation:
-30 = 2x - 10
Next, add 10 to both sides of the equation:
-30 + 10 = 2x - 10 + 10
-20 = 2x
Finally, divide both sides by 2 to solve for x:
[tex]\LARGE\mathsf{\frac{-20}{\:2}\:=\:\frac{2x}{2}}[/tex]
x = -10Double-check the validity of x = -10:Verify whether we have the correct value for x by substituting x = -10 into the given function:
g(x) = 2(x - 5)
-30 = 2(-10 - 5)
-30 = -20 - 10
-30 = -30 (True statement).
Answer:Therefore, the value of x = -10.

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!

Answer:
a. 3 and 8
b. 17
c. 3x^2, 8x, and 17
Step-by-step explanation:
a. The coefficients of an equation are the numbers that come before the variables, in this case x. We can see there is a 3 multiplying x^2 and an 8 multiplying x, therefore the coefficients would be 3 and 8.
b. The constants are the numerical terms(ones without x). This would be 17.
c. Terms are the products of numbers and/or variables separated by addition or subtraction. These would be 3x^2, 8x, and 17.
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

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.

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

Through: ( -1,5), parallel to y=-2x+1
Answer:
y = -2x + 3
Step-by-step explanation:
Parallel Lines:Parallel lines are lines with the same slope (m), but a different y - intercept (b).
The basic equation of a line is y = mx + b, where m represents slope, and b represents the y - intercept
Solving for the Line:First solve for the parallel slope of -2
Parallel slope to -2 = -2
Next, input the x and y values given to you by the point to the equation
y = -2x + b
We will input the -1 and 5 for x and y in the equation y = -2x + b
5 = -2(-1) + b
5 = 2 + b
b = 3
The line is y = -2x + 3
