Answer:
C) (-1,-4)
Step-by-step explanation:
f((x) = 3x -1
Substitute x = 0 (f (x) = 0)
0 = 3x-1
Move the variable to the left:
-3x = -1
Divides both sides by -3
X = 1/3

Step-by-step explanation:
You would just add 5 and 4 and 10 to get 19 and since there are 5 peaches it would be 5:19.
the sales of a particular brand of children’s athletic shoes rose from 6900000 to 7500000. find the percent of increase in sales. round to the nearest tenth of a percent if necessary
Answer:
6900000 + (6900000 * x) = 7400000
This equation is telling us 6900000 plus 6900000 times a specific percent will get you 7400000, which is what you want.
6900000 + (6900000 * x) = 7400000
6900000 + 6900000x = 7400000
Subtract 6900000 from both sides.
6900000x = 500000
Divide both sides by 6900000
x = 0.0724637681, or .07 when rounded to the nearest tenth.
convert .07 to a percentage by moving the decimal point two places to the right.
.07 = 7%
The sales of the children's athletic shoes rose about 7%

Julie and Ryan want to refinish the gym floor at the community center. The rectangular floor is 15.2 meters wide and 25.6 meters long. If each gallon of polyurethane covers about 180 square meters, how many gallons should they buy?
Answer:
3 gallons
Step-by-step explanation:
We need to find the area of the floor first:
25.6*15.2=389.12
Now we divide the surface area by gallons of polyurethane.
389.12÷180=2.161777777777777777777777777777....≈2.16 gallons needed. But OH WAIT! You can't buy 0.16 of a gallon so you need 3 gallons.

A cylinder has a base diameter of 8 centimeters and a height of 7 centimeters.what is its volume in cubic centimeters,to the nearest tenths place
The volume of the cylinder is approximately 351.9 cubic centimeters.
What is a cylinder?A cylinder is a 3-D figure that has a radius and a height.
The volume of a cylinder is given as πr²h.
Example:
The volume of a cup with a height of 5 cm and a radius of 2 cm is
Volume.
= 3.14 x 2 x 2 x 5
= 62.8 cm³
We have,
The volume of a cylinder can be calculated using the formula:
V = πr²h,
where r is the radius of the base and h is the height.
Since the base diameter is given as 8 centimeters, the radius is half of that or 4 centimeters.
Substituting these values into the formula, we get:
V = π (4 cm)² (7 cm)
V ≈ 351.86 cm³
Rounding this answer to the nearest tenth gives a final answer of V ≈ 351.9 cm^3.
Therefore,
The volume of the cylinder is approximately 351.9 cubic centimeters.

write an equation in standard form for the line that passes through (3,-1) and (-5,-3)
Answer:
y = 1/4x - 1.75
Step-by-step explanation:
standard form is y = mx + b
to get m you need to calculate the slope between the given points
m= (y1-y2)/(x1-x2)
m = (-1 - (-3))/(3 - (-5)) = 2/8 = 1/4
now you need to find the constant b by plugging in one of your points
y = 1/4x + b
-1 = 1/4(3) + b
b = -1 - (3/4)
b = -7/4 or -1.75
Answer:
0 = x - 4y - 7
Step-by-step explanation:
Moving from (-5, -3) to (3, -1), we see that x (the run) increases by 8 and y (the rise) incrases by 2. Thus, the slope of the line connecting these two points is m = rise / run = 2/8, or 1/4.
Use the slope-intercept form of the equation of a straight line first:
y = mx + b becomes -1 = (1/4)(3) + b, or (after multiplying all three terms
by 4) -4 = 3 + 4b. Then 4b = -7, and b = -7/4.
Then the desired equation is y = (1/4)x - 7/4, or
4y = x - 7, or
0 = x - 4y - 7. This is the desired equation in standard form.

Pack 2: 12 X 300 g cans for $24.99
Pack 3: 9 X 400 g cans for $25.99
Pack 4:6 X 1 kg can for $38.50
Which of the following shows the packs ordered from best to worst buy? Select the correct
answer A, B, C or D.
A 4213
B 3214
C 4123
D 2134
Answer:
C. 4123.
Step-by-step explanation:
We calculate the cost of a gram of cat food for each package.
Pack 1: Cost of 1 gram = total cost / number of grams
= 39.99 / (24 * 250)
= $0.00665 '
Pack 2: The cost is 24.99 / (12 * 300)
= $0.00694.
In a similar way
Pack 3: The cost is $ 0.0722
Pack 4: The cost is $0.00642 .

Tony will rent a car for the weekend. He can choose one of two plans. The first plan has an initial fee of $38 and costs an additional $0.13 per mile driven
The second plan has an initial fee of $49 and costs an additional $0.09 per mile driven
for what amount of driving do the two plans cost the
What to the cout when the two plans cout the same?
Answer:
He need to cover 275 miles for same cost for both plans
Step-by-step explanation:
Let x be the no. of miles
Case 1 :
Initial fee = $38
Additional cost of 1 mile = 0.13
Additional cost of x miles = 0.13x
So, total cost = 38+0.13x
Case 2 :
Initial fee = $49
Additional cost of 1 mile = 0.09
Additional cost of x miles = 0.09x
So, total cost = 49+0.09x
Now we are supposed to find amount of driving do the two plans cost the same
So, 38+0.13x=49+0.09x
0.13x-0.09x=49-38
0.04x=11
[tex]x=\frac{11}{0.04}[/tex]
x=275
Hence he need to cover 275 miles for same cost for both plans

Answer:
B. y= 2x–15
Step-by-step explanation:
The equation that represents the line that passes through the points (8, 1) and (10,5) is y= 2x–15
"x" is found on the left hand side of the bracket and "y" is found on the right hand side of the bracket :)
(8, 1) and (10, 5)
x in the first bracket is 8 and x in the second bracket is 10.
y in the first bracket is 1 and y in the second bracket is 5.
When this equation is applied to find the value for y we get:
y= 2x-15
y= 2(8)-15
y= 16-15
y= 1
y= 2x-15
y= 2(10)-15
y= 20-15
y= 5
We got back the values of y and this means that the equation was correctly chosen and the answer is correct :)

Two classmates, Aisha and Brandon, want to attend two school activities
over the coming weekend. They have one parking pass between them. The

0.71

0.89
They decide to let the person more likely to attend both events have the
parking pass. Assuming that attendance at one activity is independent of
attendance at the other, who is more likely to attend both activities?
A. Aisha. She has a 0.61 probability of attending both activities.
B. Brandon. He has a 0.71 probability of attending both activities.
C. Brandon. He has a 0.63 probability of attending both activities.
Answer:
C. Brandon. He has a 0.63 probability of attending both activities.
Step-by-step explanation:
Probability of attending Probability of attending
the Saturday activity the Sunday activity
Aisha 0.90 0.68
Brandon 0.71 0.89
Given that attendance at one activity is independent of attendance at the other, the probability that Aisha attends both activities is: 0.9*0.68 = 0.61, and the probability that Brandon attends both activities is: 0.71*0.89 = 0.63
Brandon has a 0.63 probability of attending both activities.
The correct option is (C).
What is probability?Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event.
Probability of attending Probability of attending
( Saturday) ( Sunday )
Aisha 0.90 0.68
Brandon 0.71 0.89
As, attendance at one activity is independent of attendance at the other activity.
P( Aisha attends both activities)
=0.9*0.68
= 0.61,
P(Brandon attends both activities)
= 0.71*0.89
= 0.63
Hence, Brandon. He has a 0.63 probability of attending both activities.

*EDITED TO SEE BOTH DIAGRAMS* MEANT TO SAY BIOLOGY NOT MATH
In class, Malik and Deniz were learning about evolution. They studied the two diagrams below.
Diagram A shows four animals as embryos: a fish, an amphibian, a bird, and a human. Diagram
B shows these animals as adults.
Molik and Deniz noticed that all four organisms have gill slits in their embryonic stage and made
the following statements
Malik said, "I think all four organisms have a common ancestor because they all share a
common characteristic, gill slits, in the embryonic stage."
Deniz said, "I dont think they all descended from a common ancestor, because when they
are adults, they do not all have gills or share many other similar physical characteristics."
1. Who do you agree with? Include information about the evolution in your response. [3]
Answer:
Deniz, as he would be correct because those images of the embryos were classified as fraud, so Malik's theory could not be true in the first place becuase the images are not based on reality, but the pictures that Deniz are using as the backup for his theory are true so his statement would be true...
idk if your school can take that as an answer but that is the truth, so just in case here is an alternate answer
Deniz because the only time the organisms are similar in appearance is for a short period of time, then they drastically change in appearance, never to share common characteristics again, if they were from the same ancestor they would all have characteristics pointing to each other and there ancestor
