Answer:
The slope is -1/6
Step-by-step explanation:
6. Describe why the following answer is incorrect and what the correct answer should be?
Write an equation in slope-intercept form whit the given information.
Goes through the points (1, -2) and (3, 6)
Answer:
The equation in slope-intercept form is:
y=4x-6Step-by-step explanation:
Given the points
(1, -2)(3, 6)Finding the slope
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(1,\:-2\right),\:\left(x_2,\:y_2\right)=\left(3,\:6\right)[/tex]
m = (6-(-2)/(3-1) = 8/2 = 4
Thus, the slope is m = 4
MISTAKE AND CORRECTION
NOTE: HERE THE PERSON MADE A MISTAKE.
Because, his slope m=2, which is incorrect.Thus, the person found the slope incorrectly.The correct slope = m = 4
The slope-intercept form is
y=mx+b
Plug in (3, 6) and m=4 to find b
6 = 4·3 + b
6 = 12+b
6-12 = b
-6 = b
Plug in m=4 and b=-6 in the slope-intercept form
y=mx+b
y=4x+(-6)
y=4x-6
Thus, the equation in slope-intercept form is:
y=4x-6
Graph the function ƒ(x) = x by pressing Y= and entering the function’s rule next to Y1 =. As shown, the graph of the function is a line that makes a 45° angle with each axis.
What are the slope and y-intercept of the graph of ƒ(x) = x?
Solve the inequality: 4x + 7.5 >x- 4.5
Answer:
x > -4
Step-by-step explanation:
The variable m in slope intercept form represents the y- intercept ? True or false
No.
m represents the slope while b represents the y-intercept.
Answer: False
Step-by-step explanation:
Because the slope-intercept form is y=mx+b and m represents slope.

Answer: Si COMPREISO
Step-by-step explanation:
Given Sn=2n^2 - 5n, find
(a) first term
(b) 9th term
(c) sum of the terms from the 4th term to the 8th term
Answer:
a) -3
b) 117
c) 100
Step-by-step explanation:
(a) 2(1)²-5(1)
1²= 1
2×1= 2
2-5= -3
(b) 2(9)²-5(9)
9²= 81
81×2= 162
162-45= 117
(c) 2(4)²-5(4) +2(8)²-5(4)
4²=16
16×2= 32
32-20= 12
8²=64
64×2= 128
128-40= 88
88+12= 100
hope it helps!
7. Which situation could be represented by the graph below?
a. The speed increases and then decreases.
b. The speed increases and then remains constant.
c. The speed stays constant and then increases
d. The speed decreases and then remains constant.

Time
HELP PLZ
Answer:
b. The speed increases and then remains constant. You can see that in the beginning there is a larger slope, which indicates a faster speed, followed by a plateau, which shows a consrant speed.
Layla says that -3(5) = 15. Which statement explains why Layla is correct or incorrect
Answer:
The answer is suppose to be -15.
Step-by-step explanation:
I do not see any statements
I can give you an explanation
Layla forgot to carry the negative
Answer:
She is incorrect because -3(5) is -15 since when you multiple a positive and a negative number you get a negative number.
Step-by-step explanation:
Which table does not show a direct variation?
Answer:
Table J
Step-by-step explanation:
A direct variation is a simple relationship between x and y.
When you are looking for the direct relationship you should use the formula for it y=kx, or you could just divide y over x ([tex]\frac{y}{x}[/tex]).
Analysing Table F:
The relationship between x and y is 4.
[tex]\frac{-8}{-1}=4\\\\\frac{-4}{-1}=4\\\\\frac{0}{0}= origin\\\\\frac{4}{1}=4[/tex]
The origin is fine and doesn't ruin the relationship.
Analysing Table G:
The relationship between x and y is 5.
[tex]\frac{5}{1}=5\\\\\frac{10}{2}=5\\\\\frac{15}{3}=5\\\\\frac{20}{4}=5[/tex]
Analysing Table H:
The relationship between x and y is [tex]\frac{1}{3}[/tex].
[tex]\frac{0}{0}=origin\\\\\frac{1}{3}=\frac{1}{3}\\\\\frac{2}{6}=\frac{1}{3}\\\\\frac{3}{9}=\frac{1}{3}[/tex]
Like I said before the origin doesn't ruin the relationship so it's fine.
Analysing Table J:
This one doesn't have a direct relationship between x and y.
[tex]\frac{1}{1}=1\\\\\frac{4}{2}=2\\\\\frac{9}{3}=3\\\\\frac{16}{4}=4[/tex]

Anybody know the answer to this
Answer:
1. sin(Z) = 0.6
2. sin(C) = 0.28
3. cos(Z) = 0.8
4. tan(C) = 0.75
5. tan(50°) = 1.1918
6. cos(40°) = 0.7660
7. sin (25°) = 0.4226
8. sin(75°) = 0.9659.
Step-by-step explanation:
The trigonometric ratios are
[tex]cos \ \theta = \dfrac{Adjacent\ leg \ length}{Hypotenuse \ length}[/tex]
[tex]sin \ \theta = \dfrac{Opposite \ leg \ length}{Hypotenuse \ length}[/tex]
[tex]tan \ \theta = \dfrac{Opposite \ leg \ length}{Adjacent \ leg \ length}[/tex]
1. The length of the opposite leg to angle Z = 24
The length of the hypotenuse side = 40
∴ sin(Z) = 24/40 = 0.6
2. The length of the opposite leg to angle C = 14
The length of the hypotenuse side = 50
∴ sin(C) = 14/50 = 0.28
3. The length of the adjacent leg to angle Z = 24
The length of the hypotenuse side = 30
∴ cos(Z) = 24/30 = 0.8
4. The length of the opposite leg to angle C = 27
The length of the adjacent leg = 36
∴ tan(C) = 27/36 = 0.75
5. Using the calculator, and rounding the answers to the nearest 10,000, we have;
tan(50°) = 1.1918
6. Using the calculator, and rounding the answers to the nearest 10,000, we have;
cos(40°) = 0.7660
7. Using the calculator, and rounding the answers to the nearest 10,000, we have;
sin (25°) = 0.4226
8. Using the calculator, and rounding the answers to the nearest 10,000, we have;
sin(75°) = 0.9659.
Victoria has ⅓ less than the amount of money that Gabby has. If Gabby has x dollars, write an expression to represent the amount of money Victoria has in terms of x.
Answer: 2/3x
Step-by-step explanation:
From the question, we are informed that Victoria has ⅓ less than the amount of money that Gabby has and that Gabby has x dollars.
An expression to represent the amount of money Victoria has in terms of x will then be:
= x - 1/3x
= 2/3x

The volume of a rectangular box can be found with the formula v = l * w * h. Solve for l, and find the length of the rectangular box when w = 6 inches, h = 7 inches, v = 210 cubic inches.
Answer: Length =5 inches
Step-by-step explanation:
Multiply 6(w)x7(h) which gives you 42 then divide 210(v) by 42 which gets you 5(l)
Question 15 (1 point) Is this ratio statement ture or false? 4.5 and 16:18 OTrue O False

At the movies, you buy 3 bags of popcorn and 2 soft drinks and it costs you $16.50. Layne buys 2 bags of popcorn and 1 soft drink and his total is $10.25. Find the cost of one bag of popcorn and one soft drink.
Answer:
Popcorn= $4.5
Soft drink= $1.5
Step-by-step explanation:
Let p represent the cost of popcorn and let a represent the cost of soft drinks
3p + 2s= 16.50
2p + s= 10.5
Multiply equation 1 by 2 and equation 2 by 3
6p + 4s = 33
-
6p + 3s = 31.5
s= 1.5
Substitute 1.5 for s in equation 1
3p + 2s = 16.50
3p + 2(1.5)= 16.50
3p + 3 = 16.50
3p = 16.50-3
3p = 13.5
p = 13.5/3
p = 4.5
Hence the price of a bah of popcorn is $4.5 and soft drink is $1.5

Answer:
332 - x
Step-by-step explanation:
We are told that:
Kristel had 290 stickers.
Let the number of stickers given to her sister be x;
Tricia gave Kristel 42 afterwards.
To find the number of stickers Kristel gave to her sister; we have:
= 290 + 42 - x
= 332 - x

Step-by-step explanation:
In the given triangle AED,
Points B and D are the midpoints of sides AD and AE.
a). Therefore, AB = [tex]\frac{1}{2}(AD)[/tex]
AB = [tex]\frac{90}{2}[/tex] = 45 ft
b). AE = 2(AC)
AE = 2(30)
AE = 60 ft
c). By mid-segment theorem,
BC = [tex]\frac{1}{2}(DE)[/tex]
BC = [tex]\frac{50}{2}=25[/tex] ft
d). EC = AC = 30 ft
