To solve this equation, first get rid of the fractions.
We do this by multiplying both sides by the denominator, 2.
So we have (2)(1/2s) = (7/2)(2).
On the left, we have s and on the right, we have 7.
So we have s = 7.

Which model is not a function?
Answer:
C
Step-by-step explanation:
A function can not have an input that has more than one output.
In the diagram the left is the input and the right is the output. C has the input 2 having an output of -2, -1, 0, 1, and 2. That is more than one.

Since given line is parallel to x axis, so it's slope is zero.
Another way:
Line is passing through the points (2, - 1) & (3, - 1)
So,
[tex] slope=\frac{-1-(-1)}{3-2}[/tex]
[tex] slope=\frac{-1+1}{1}[/tex]
[tex] slope=\frac{0}{1}[/tex]

Solve the following problem:
Which triangles are similar? Which sides are proportional?
9514 1404 393
Answer:
ΔA₁CA ~ ΔBCB₁
Step-by-step explanation:
The triangles share angle C. The 30° angles are also congruent, so the triangles are similar by the AA theorem.
It is convenient to name the similar triangles by matching the similar angles. Here, angle A₁ matches the acute angle at B, and (of course) angle C matches itself. So, we can name the triangles using those two angles in that order.
ΔA₁CA ~ ΔBCB₁

how does 4/3y = 36??????????
Answer:
i think 27
Step-by-step explanation:
27 X 4/3y=36y
Answer:
When you find the y value and multiply it by 4/3, it equals 36.
Step-by-step explanation:
[tex] \frac{ \frac{4}{3}y }{ \frac{4}{3} } = \frac{ 36 }{ \frac{4}{3} } \\ y = 27[/tex]
[tex] \frac{4}{3} (27) = 36 \\ 36 = 36[/tex]

Which system of equations can be represented by this matrix?
Answer: C
Step-by-step explanation: As you most likely know, the matrix represents the system of equations. If you assume that x is the far left column, that y is the column adjacent to it, and that y is to the left of the line, you can assume that these are the equations represented:
1x-3y+2z=-9
1x+0y+1z=1
0x+2y-1z=7
which can be simplified to
x-3y+2x=-9
x+z=1
2y-z=7
What is 4/5 written as a percentage
Answer:
80%
Step-by-step explanation:
To write 4/5 as a percent have to remember that 1 equal 100% and that what you need to do is just to multiply the number by 100 and add at the end symbol %. 4/5 * 100 = 0.8 * 100 = 80% And finally we have: 4/5 as a percent equals 80%
Answer:
0.80
Step-by-step explanation:
1/5=0.20
1/5×4=0.80
Leanne is picking out some movies to rent, and she is primarily interested in children's movies and comedies. She has narrowed down her selections to 18 children's movies and 7 comedies. Step 2 of 2 : How many different combinations of 3 movies can she rent if she wants at least one comedy
Answer:
If she wants at least one comedy, there are 1484 different combinations.
Step-by-step explanation:
The order in which she wants to pick the movies is not important. So, we use the combinations formula to solve this question.
Combinations formula:
[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
In this question:
She wants combinations of 3 movies, with at least one comedy. The easiest way to find this is finding the total number of combinations of 3 movies, from the set of 25(18 children's and 7 comedies), and subtract by the total number without comedies(which is 3 from a set of 25). So
Total:
3 from a set of 25.
[tex]C_{25,3} = \frac{25!}{3!(25-3)!} = 2300[/tex]
Without comedies:
3 from a set of 18.
[tex]C_{18,3} = \frac{18!}{3!(18-3)!} = 816[/tex]
At least one comedy:
[tex]2300 - 816 = 1484[/tex]
If she wants at least one comedy, there are 1484 different combinations.

6. A Civil War cannon is placed at the base of a hill. The cannon is fired at an angle toward the hill. The path of the cannon ball is parabolic and can be represented by y=-0.04x2 + 4x + 1, where y represents the height of the ball in meters and x represents the horizontal distance of the ball from the cannon. The incline of the hill can be represented by the equation y = 0.8125x. How far will the cannon ball have moved horizontally from the cannon when it hits the hill?
Answer: 80
Step-by-step explanation:
Following are the solution to the given question:
Its canon is placed on the floor, as we knew from the very first part. So, for Canon, [tex]y = 0[/tex]. Consider the origin, which is located at the bottom of a hill. So, to find the canon's x value, we must solve the quadratic formula: [tex]-0.04x^2 + 4x + 1 = 0[/tex] , which has only one negative solution,[tex]0.25.[/tex] We know that the x value cannot be positive as this would suggest that the cannon is located inside of the hill. This hill's equation is[tex]y = 0.8125x[/tex] , and we understand that now the cannonball will collide with it at the junction of the hill line and its hyperbolic path. So, when the formulas are combined, we get[tex]\to 0.8125x =-0.04x2 + 4x + 1\\\\\to 0.04x^2 - 3.1875 - 1 = 0\\\\[/tex]
It has the only positive root as [tex]80[/tex]. As a result, the y value is [tex]0.8125\times 80 = 65[/tex]The horizontal distance will be the x value + the [tex]0.25 = 80.25[/tex]Its horizontal distance = x value+[tex]0.25= 80+0.25 = 80.25[/tex]Learn more:

You take out a loan from the bank for $4350. The bank charges an annual simple
interest rate of 15% and you are going to pay the loan back in 4 years. What is the
total amount of INTEREST you will pay back to the bank?
Answer:
He will have $4491.38 after 5 year
Step-by-step explanation
Simple Interest = (Principal × rate × time)/100
SI = (4350 × 0.65 × 5)/100
SI = 141.375
Interest after 5 years = $141.38
The total money he will have after 5 years is
$4350 + $141.38
= $4491.38
Answer:
I think the total amount would be $2610
Step-by-step explanation:
because you would multiply $4350 times 15% to get 652.5 a year so just multiply that by 4 and you have your answer which is $2610 the total amount of interest.
