Answer:
(A) Square root of 65
Step-by-step explanation:
We can use Pythagorean Theorem for this, as a^2 + b^2 = c^2, that means:
4^2 + 7^2 = x^2, so 16 + 49 = x^2, add 16 and 49 and you get 65. Remember though, x was squared, so we have to find the square root of 65. Making it the square root of 65 or (A) the answer.

Consider the function represented by the equation x-y = 3. What is the equation written in function notation, with x as
the independent variable?
O f(x)=y+3
O fX) =y-3
O fx) =x +3
O f(x) =X-3
Answers
Answer:
f(x) = x - 3
Step-by-step explanation:
Given
x - y = 3
Rearrange making y the subject
Subtract x from both sides
- y = - x + 3 ( multiply through by - 1 )
y = x - 3, that is
f(x) = x - 3 ← in functional notation
The function represented by the independent variable is f ( x ) = x - 3
What is a function rule?The function rule is the relationship between the input or domain and the output or range. A relation is a function if and only if there exists one value in the range for every domain value.
A function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.
Given data ,
Let the function be represented as f ( x )
Now , the value of the function is
x - y = 3 be equation (1)
Adding y on both sides , we get
y + 3 = x
Subtracting 3 on both sides , we get
y = x - 3
Now , changing y to x to make it independent , we get
f ( x ) = x - 3
Hence , the function is f ( x ) = x - 3

PLEASE HELP!! You have to solve for x but it’s the similar triangles way
Answers
Answer:
x = 26
Step-by-step explanation:
A segment joining the midpoints of 2 sides of a triangle is half the length of the third side, thus
x + 9 = [tex]\frac{1}{2}[/tex](3x - 8) ( multiply both sides by 2 to clear the fraction )
2(x + 9) = 3x - 8
2x + 18 = 3x - 8 ( subtract 2x from both sides )
18 = x - 8 ( add 8 to both sides )
26 = x
Aldo spends $14 each time he travels the toll roads. He started the month with $224 in his toll road account. The amount, A
(in dollars), that he has left in the account after trips on the toll roads is given by the following function.
A (t) = 224 - 14
Answer the following questions.
(a) How much money does Aldo have left in the account after 11 trips on the toll
roads?
(b) How many trips on the toll roads can he take until his account is empty?
trips
Answers
Part b.) 16 times. He has $224 total. You want to find out how many times he can go on the tool roads. We know the toll roads cost $14 each time. So you do $224/14 and get an even amount of 16. He would be able to use it 16 times before he have no money left.

Answer:
240 miles
Step-by-step explanation:
If x is 4 hours and d(x) represents the amount of distance traveled, then we would choose the expression that allows us to find d(x).
Since x = 4 and 4 is greater than 2 but less than 5, we will choose the second expression 2 < x [tex]\leq[/tex] 5.
We will then plug our x-value (4) into the expression to find d(x).
If d(x) = 65x - 20
d(x) = 65(4) - 20
d(x) = 260 - 20
dx) = 240 miles
Hi there.
The answer is 240 miles.
Explanation:
As our x-term is represented as hours. Meaning our d(x) is represented as the distance.
Travel in 4 hours, meaning we have to substitute x = 4.
Both functions have given and specified domains. Which function doesn't have x = 4 as a part of the domain. That is the first function, thus the first function is out.
Our main function is currently —
[tex]d(x) = 65x - 20[/tex]
As x is represented as hours. Substitute x = 4 in the function.
[tex]d(4) = 65(4) - 20 \\ d(4) = 260 - 20 \\ d(4) = 240[/tex]
Thus, the answer is d(4) = 240 miles.

One Strength of the British is that they have very well trained army. Another British Strength is that they had way more soldiers than the Americans did. A British weakness is that they did not know the land like the americans did. Also lacked motivation to crush the opposition from the onset of the war. AN AMerican strength would be that they know the land way more than the British did so they got to move around more. They also had very good leadership. An American weakness is that they had very little finance in the war. Another weakness is the soldiers weren't as well trained as the British.

What is the x intercept?
What is the y intercept?
Answers
Answer:
(The X intercept is 3) and (the Y intercept is -2)
Step-by-step explanation:
find x intercept by substituting y=0
2x-3×0=6
any expression multiplied by 0 equals 0
2x-0=6
when adding or subtracting 0, the quantity never changes
2x=6
divide both sides of the equation by 2
x=3
find Y intercept by substituting x = 0
2×0-3y=6
solve the equation for y
y=-2

Step-by-step explanation:
Step 1: Define equation
3t - 18 = 4(-3 - 3/4t)
Step 2: Solve for t
Distribute 4: 3t - 18 = -12 - 3tAdd 3t to both sides: 6t - 18 = -12Add 18 to both sides: 6t = 6Divide 6 on both sides: t = 1Step 3: Check
Plug in t into the original equation to verify it's a solution.
Substitute in t: 3(1) - 18 = 4(-3 - 3/4(1))Multiply: 3 - 18 = 4(-3 - 3/4)Subtract: -15 = 4(-15/4)Multiply: -15 = -15Here we see that -15 does indeed equal -15.
∴ t = 1 is a solution of the equation.

there is 16 fifth graders and 36 sixth graders. To be fair, coach matt wants there to be the same number of fifth graders and the same number of sixth grader on each team
Answers
Answer:
There are 4 teams coach Matt could have
Each team consist of
4 Fifth graders per team and
9 Sixth graders per team
Step-by-step explanation:
Fifth graders = 16
Sixth graders = 36
Find the highest common factor of 16 and 36
16 = 1, 2, 4, 8, 16
36 = 1, 2, 3, 4, 6, 9, 12, 18, 36
The highest common factor of 16 and 36 is 4
Therefore,
There are 4 teams coach Matt could have
Fifth graders per team = 16 / 4
= 4 Fifth graders per team
Sixth graders per team = 36 / 4
= 9 Sixth graders per team
Answer:
4 5th graders and 9 6th graders
