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 :)
How many students got eight or more answers correct?
Answer:
9
Step-by-step explanation:
You have to count the number of dots there are after the number 8. (This includes the dotes above 8.)
Answer:
9 students
Step-by-step explanation:
Assuming that these dots represent students, let us begin with the amount of students that answered 8 questions right;
Students who got 8 answers right ⇒ 4 students,
Students who got 8 answers right ⇒ 3 students,
Students who got 10 answers right ⇒ 2 students
Now we are to compute the value of the students who received 8 or more answers right, provided the questions are out of 10;
Students who received 8 or more answers right; 4 + 3 + 2 = 9 students
Solution; 9 students

Answer:D
Step-by-step explanation:
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.
*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

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.

If 120 V is applied to refrigerator with a resistance of 14.0 2, calculate the
current flowing through the refrigerator.
Answer:
The current is approximately 8.571 Amps
Step-by-step explanation:
You are supposed to use Ohm's Law for this problem.
Recall that Ohm's Law gives you the relationship between voltage applied (V), resistance (R) and current (I):
[tex]V=I\,*\,R[/tex]
If the units of resistance are ohms, and the voltage is in volts, the current will be given in Amps (amperes). Then solving for the current (I) in the above equation:
[tex]I=\frac{V}{R} \\I=\frac{120}{14} \\I=8.571\,\,Amps[/tex]

What is the area of the trapezoid above?
26 centimeters squared
80 centimeters squared
8.5 centimeters squared
208 centimeters squared
Answer:
26 square meters (the first option)
Step-by-step explanation:
The area of a trapezoid is (b1+b2)/2*h.
b1=one of the bases (one of the bases that are parallel to each other)
b2= the other base (that is parallel to base 1)
h=height
In this picture, b1=5, b2=8, h=4
So, the area is
(5+8)/2*4
=13/2*4
=6.5*4
= 26 square meters

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%

Answer:
1- longest side
2- adjacent and opposite
3-a^2 + b^2 = c^2
4- yes, by using pythagorean theorem
Step-by-step explanation:
1- the hypotenuse is always the longest side
2- the three sides are called hypotenuse, adjacent and opposite
3- a^2 + b^2 = c^2 is a formula to solve for missing legs
4- pythagorean theorem (a^2 + b^2 = c^2) is the formula to solve for missing legs/hypotenuse . A and B represents a leg and c will always be the hypotenuse, you then isolate for the letter you are missing

Probability of attending
the Saturday activity
Probability of attending
the Sunday activity
0.68
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.

A 13 ft ladder is laying on a wall, the angle the ladder makes with the floor is 45 degrees.
How high off the ground is the top of the ladder? Use the function y = 13cos (θ)
Answer:
9.1924
Step-by-step explanation:
if you make a model the 13 foot ladder is the hypotenuse and the height off the ground is the opposite. so you would you sin. this is what the equation would look like. sin(45)=x/13
now just multiply 13 to sin(45)
*i know it says to use y=13cos but i don't see why you would use that to find the height of the wall, but I might be wrong on how to do it, this is just how I learned and is what my level of math is.
