Answers
Answer:
B.
Step-by-step explanation:
If you want to find a table with a proportional relationship, you are looking for one where the x-values and y-values increase at the same linear rate.
In Option A, the x-values increase steadily by 1 and then by 2, but the y-values jump around. The numbers are not proportional.
In Option B, every time an x-value is presented, the y-value is two times the value of x. So, this is a proportional relationship.
In Option C, it is true that for almost every time an x-value is presented, the y-value doubles the x-value, but when x is 0, y is 1. That is not a proportional relationship.
In Option D, it is the same thing as Option A.
So, your answer is Option B.
Hope this helps!

Answer:
Multiplication property of equality
Step-by-step explanation:
Given
Step 4: b = -27/8
Required
Which property justifies it?
First, it should be noted that step 4 is a result of step 3
When step 3 is multiplied by 3/8 on both sides, we have step 4;
i.e.
[tex]\frac{8}{3b} = -9[/tex]
[tex]\frac{8}{3b} * \frac{3}{8} = -9 * \frac{3}{8}[/tex]
[tex]b = -9 * \frac{3}{8}[/tex]
[tex]b = \frac{-9 * 3}{8}[/tex]
[tex]b = \frac{-27}{8}[/tex]
The property that allows 3/8 be multiplied on both sides is referred to as the multiplication property of equality
Which of the following equations has a solution of x = -5?
a. Equation A
b. Equation B
c. Both A and B
d. Neither A nor B
Answers
Answer:
C. Both A & B
Step-by-step explanation:
Solve the equations given:
Equation A:
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
First, subtract 11x and add 7 to both sides:
16x (-11x) - 7 (+7) = 11x (-11x) - 32 (+7)
16x - 11x = -32 + 7
Simplify. Combine like terms:
16x - 11x = -32 + 7
5x = -25
Isolate the variable, x. Divide 5 from both sides:
(5x)/5 = (-25)/5
x = -25/5
x = -5
Equation A is an answer choice.
Equation B:
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
First, add 10 & subtract 2x from both sides:
-4x (-2x) - 10 (+10) = 2x (-2x) + 20 (+10)
-4x - 2x = 20 + 10
Simplify. Combine like terms:
-4x - 2x = 20 + 10
-6x = 30
Isolate the variable, x. Divide -6 from both sides:
(-6x)/-6 = (30)/-6
x = 30/-6
x = -5
Equation B is also an answer choice.
C. Both A & B is your answer.

Answer:
The bird has to fly 7.5 m
Step-by-step explanation:
Please see diagram in attached image.
Notice that there is a right angle triangle that defines the situation, and you know two elements of such triangle;
1) one acute angle ([tex]15^o[/tex]), and
2) the side opposite to that angle.
What you need to find is the side adjacent to the angle, which is what the bird needs to fly horizontally to be above the fish. We named that "x".
The trig function that relates such triangle elements is the tangent:
[tex]tan(\theta)=\frac{opposite}{adjacent} \\tan(15^o)=\frac{2\,m}{x} \\x=\frac{2\,m}{tan(15^o)} \\x=7.46 \,\,m[/tex]
which rounded to the nearest tenth is: 7.5 m
Grace's mom gave her $15.00 to buy school supplies. Grace needs to buy 3 mechanical pencils and some notebooks. If each mechanical pencil costs $1.75 and each notebook costs $2.99, how many notebooks can Grace buy using only the money her mom gave her? 2 notebooks 3 notebooks 4 notebooks 5 notebooks
Answers
Answer: 3 notebooks
Step-by-step explanation:
First take the three mechanical pencils out of the equation by doing
15 - (3*1.75) = 9.75. Because each notebook costs 3 dollars, she can afford 3 notebooks, with 1 dollar left over.
Hope it helps <3
Answer:
3 notebooks
Step-by-step explanation:
(1,75x3)=5.25 15.00-5.25=9.75
2.99x=9.75
x=3,26
so she can buy 3 notebooks

what is the probability of rolling a 3 on two consecutive rolls of a fair 6-sided die?

Step-by-step explanation:
Each time you roll a die, you have a [tex]\frac{1}{6}[/tex] chance of rolling a 3. It's even rarer to roll two 3s in a row, and to find a consecutive probability, we have to multiply the two probabilities. In this case, both probabilities are [tex]\frac{1}{6}[/tex].

Apples cost $0.75 per pound and bananas cost $1.15 per pound. Leah bought a total of 13
pounds of apples and bananas for $12.55. The system of equations
a+b = 13
0.750 + 1.15b = 12.55 models this situation, where a is the number of pounds of
apples and b is the number of pounds of bananas. How many pounds of each did Leah buy?
Leah bought
pounds of apples and
pounds of bananas.
Answers
Answer:
Step-by-step explanation:
Let's solve the given system of linear equations:
a+b = 13
0.750 + 1.15b = 12.55
Let's eliminate b. To do this, solve the first equation for b, obtaining b = 13 - a, and then substitute 13 - a for b in the second equation:
0.750 + 1.15(13 - a) = 12.55.
Next, subtract 0.750 from both sides, obtaining: 1.15(13 - a) = 11.8
Dividing both sides by 1.15 yields 13 - a = 10.26
Then a = 13 - 10.26, or a = 2.74.
Since a + b = 13, b = 13 - 2.74, or 10.26
This person bought 2.74 pounds of apples and 10.26 pounds of bananas.

Tom wants to save $846, he already has $23, and he deposits $87 each month, M.
Answers
Answer:
The answer is C.
Answer:
B. Tom wants to save $846, he already has $87, and he deposits $23 each month, M.
Step-by-step explanation:
$846 = $87 + $23M
The $846 represents the amount that he wants to save. $23M represents how much money he wants to deposit every M months. $87 represents the amount that he has already deposited (the constant).
And so, the correct answer will be B. Tom wants to save $846, he already has $87, and he deposits $23 each month, M.

In general for a rectangle of dimensions w by h and a semicircle of diameter w we get an area:
A = wh + \frac 1 2 \pi (\frac w 2)^2
The halfs are because a semicircle is half a circle and a radius is half a diameter.
We're told
h = 1+ 3w
Substituting,
A(w) = w(1+3w) + \frac 1 2 \pi (\frac w 2)^2

Find (F/g)(x)
F(x) = sqrt x^2-1
g(x) sqrt x-1
Answers
Answer:
Option A. √(x + 1)
Step-by-step explanation:
Data obtained from the question include:
f(x) = √(x² – 1)
g(x) = √(x – 1)
(f/g) (x) =..?
(x² – 1) => difference of two square
(x² – 1) => (x – 1)(x + 1)
f(x) = √(x² – 1)
f(x) = √(x – 1)(x + 1)
(f/g) (x) = f(x) /g(x)
f(x) = √(x – 1)(x + 1)
g(x) = √(x – 1)
(f/g) (x) = √(x – 1)(x + 1) / √(x – 1)
(f/g) (x) = √[(x – 1)(x + 1) / (x – 1)]
(f/g) (x) = √(x + 1)

Good luck on your assignment..
Explanation:
3/4(2-3x)=0
(6-9x)/4=0
6-9x=0 x 4
6-9x= 0 (any number time 0 is 0)
-9x=-6
x=-6/-9
x=2/3
Now let’s use x in our equation
3/4(2-3x)=0
now plug x=2/3
3/4(2-3 x 2/3)=0
3/4(2-6/3)=0
3/4(2-2)=0
3/4(0)=0
0=0 (any number time 0 is 0)
And so x = 2/3 is the right answer

Two circles of radii 3cm and 4cm have the same total area as a third circle.What is the radius of the third circle.
Answers
Answer:
5 cm
Step-by-step explanation:
Area of 3 cm circle
A = pi r^2 = pi *3^2 = 9pi
Area of 4 cm circle
A = pi r^2 = pi *4^2 = 16pi
The area of the new circle is 16pi+9pi = 25 pi
25 pi = pi r^2
Divide each side by pi
25 = r^2
Take the square root of each side
sqrt(25) = sqrt(r^2)
5 = r
The radius is 5
