Find the value of x for which a || b
Answers
Answer:
Since a and b are parallel
Step-by-step explanation:
2x+27=3x - 27
collect the like terms
3x-2x=27+27
x=54
PLS MARK BRAINLIEST
Answer:
x = 54
Step-by-step explanation:
If the lines are treated as parallel , then
(3x - 27) and (2x + 27) are alternate exterior angles and congruent, so
3x - 27 = 2x + 27 ( subtract 2x from both sides )
x - 27 = 27 ( add 27 to both sides )
x = 54
For a and b to be parallel then x = 54

There's a roughly linear relationship between the length of someone's femur (the long
leg-bone in your thigh) and their expected height. Within a certain population, this
relationship can be expressed using the formula h = 63.4 +2.41f, where h
represents the expected height in centimeters and f represents the length of the
femur in centimeters. What is the meaning of the f-value when h=123?
Answers
Answer:
24.73
Step-by-step explanation:
h=63.4+2.41f
h=123
123=63.4+2.41f
59.6=2.41f
24.73=f
If the value of h is 123. Then the length of the femur will be 24.73 centimeters.
What is a linear equation?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
The linear equation is given below.
h = 63.4 + 2.41 f
Where h represents the expected height in centimeters and f represents the length of the femur in centimeters.
If the value of h is 123. Then the f-value is given as,
123 = 63.4 + 2.41 f
2.41 f = 59.60
f = 24.73 cm
Assuming that the worth of h is 123. Then, at that point, the length of the femur will be 24.73 centimeters.

The area of a square is 676 square root. what is the perimeter of the square?
Answers
Answer:
the perimeter of the square is 104
Step-by-step explanation:
to find the perimeter of a square we need to use the formula P = 4a
P is perimeter and a is the side of the square
if a is the side and the formula of Area is A = a^2
that means the side of the square is a = 26 because 26 * 26 = 676
now we take 26 and place it in the a spot of the perimeter formula
P = 4 * 26 (P = 104)

The number T of teams that have participated in a robot-building competition for high-school students over a recent period of time x(in years) can be modeled by T(x) = 17.155x^2 + 193.68x + 235.81, 0 ≤ x ≤ 6.
After how many years is the number of teams greater than 1000? Justify your answer.
Answers
Solving the quadratic equation, it is found that the number of teams is greater than 1000 after 3.1 years.
The number of teams after x years is given by:
[tex]T(x) = 17.155x^2 + 193.68x + 235.81[/tex]
Initially, there are T(0) = 236 teams. If will 1000 be when T(x) = 1000, thus:
[tex]17.155x^2 + 193.68x + 235.81 = 1000[/tex]
[tex]17.155x^2 + 193.68x - 764.19 = 0[/tex]
Which has coefficients [tex]a = 17.155, b = 193.68, c = -764.19[/tex], then:
[tex]\Delta = (193.68)^2 - 4(17.155)(-764.19) = 89950.66[/tex]
[tex]x_{1} = \frac{-193.68 + \sqrt{89950.66}}{2(17.155)} = 3.1[/tex]
[tex]x_{2} = \frac{-193.68 - \sqrt{89950.66}}{2(17.155)} = -14.3[/tex]
We want the positive root, so the number of teams is greater than 1000 after 3.1 years.

Step-by-step explanation:
Assume that '2' is an exponent.
So the question for you should be:-
[tex] \displaystyle \large{h(x) = {x}^{2} - x}[/tex]
We want to find h(5); we substitute x = 5 in.
[tex] \displaystyle \large{h(x) = {5}^{2} - 5}[/tex]
5^2 is 5•5 = 25.
[tex] \displaystyle \large{h(x) = 25 - 5} \\ \displaystyle \large{h(x) = 20}[/tex]
Therefore, h(5) is 20.

Answers
Answer:
y = -5x + 22 is the equation of our parallel line
Step-by-step explanation:
remember a parallel line will have the same slope.
So let's begin by using the equation above and substituting the points.
[tex]y = - 5x + b \\ - 8 = - 5(6) + b \\ - 8 = - 30 + b \\ 30 - 8 = b \\ b = 22[/tex]

answer that appears in the "Out" box of Machine B.
What was the answer produced by both machines?
Show how you figured it out
Answers
The machines represent equivalent expressions.
The output produced by both machines is 372
The equation represented on machine A is:
[tex]\mathbf{y = 2(5x + 3) - 24}[/tex]
The equation represented on machine B is:
[tex]\mathbf{y = 4(2(x + 11) - 7)}[/tex]
Where: x and y represent the inputs and the outputs, respectively
When the outputs are the same, it means:
[tex]\mathbf{y = y}[/tex]
So, we have:
[tex]\mathbf{2(5x + 3) - 24 = 4(2(x + 11) - 7)}[/tex]
Open brackets
[tex]\mathbf{10x + 6 - 24 = 8x + 88 - 28}[/tex]
[tex]\mathbf{10x - 18 = 8x + 60}[/tex]
Collect like terms
[tex]\mathbf{10x - 8x = 18 + 60}[/tex]
[tex]\mathbf{2x = 78 }[/tex]
Divide both sides by 2
[tex]\mathbf{x = 39 }[/tex]
Substitute 39 for x in [tex]\mathbf{y = 2(5x + 3) - 24}[/tex]
[tex]\mathbf{y = 2 \times (5 \times 39 + 3) - 24}[/tex]
[tex]\mathbf{y = 372}[/tex]
Hence, the output produced by both machines is 372
