PLEASE HELP I NEED THIS
Answer:
x = 2
UV = 9 ft
VW = 6 ft
WU = 5 ft
Step-by-step explanation:
The perimeter of a figure can be represented as the sum of lengths of all of its sides. In this case we can write:
P = UV + VW + WU
Now, we can substitute the values which we have:
20 = 4x + 1 + 8 - x + 2x + 1
We can combine like terms...
20 = 5x + 10
5x = 10
x = 2
Since UV is represented by 4x + 1, we can substitute in x to find its length.
UV = 4x + 1
UV = 4(2) + 1
UV = 6 + 1
UV = 9
We can do the same for the other two sides:
VW = 8 - x
VW = 8 - 2
VW = 6
WU = 2x + 1
WU = 2(2) + 1
WU = 4 + 1
WU = 5
Solve for b.
-3b+2.5 = 4
Answer:
b = −0.5
Step-by-step explanation:
Let's solve your equation step-by-step.
−3b+2.5=4
Step 1: Subtract 2.5 from both sides.
−3b+2.5−2.5=4−2.5
−3b=1.5
Step 2: Divide both sides by -3.
-3b/-3 = 1.5/-3
The value of 'b' in the equation given is -0.5
Given the expression for which we could solve for the unknown:
-3b + 2.5 = 4Subtract 2.5 from both sides
-3b = 4 - 2.5
-3b = 1.5
divide both sides by -3 to isolate b
-3b/-3 = 1.5/-3
b = -0.5
Therefore, the value of b in the equation given is -0.5

The figure shows the graphs of the functions y = f(x) and y = g(x). The four indicated points all have integer coordinates. y = f(x) y = g(x) If g(x) = k f(x), what is the value of k? I am not sure how to do this. k = -3
Answer:
k = -3
Step-by-step explanation:
f(x) = -2x+1
g(x) = 6x - 3
=> g(x) = k.f(x)
6x - 3 = k(-2x+1)
k = (6x-3)/(-2x+1)
= 3(2x-1)/-1(2x-1)
k = 3/(-1) = -3
The value of k for the given function will be k = -3.
What is a function?In mathematics, a function is a relation between a set of inputs and a set of possible outputs with the property that each input is related to exactly one output. A function can be thought of as a machine that takes an input, performs a certain operation on it, and produces an output.
Formally, a function is defined as a set of ordered pairs (x, y) such that each value of x is associated with exactly one value of y. The set of all possible inputs to a function is called its domain, while the set of all possible outputs is called its range.
The given functions are,
f(x) = -2x+1
g(x) = 6x - 3
The value of k will be calculated as,
g(x) = k.f(x)
6x - 3 = k(-2x+1)
k = (6x-3)/(-2x+1)
k= 3(2x-1)/-1(2x-1)
k = 3/(-1) = -3

Devin buys four shirts of equal price for a total of 36$ and teo pairs of shoes for equal price of $25.He has to pay 8% sales tax on his purchases devin decides instead to purchase five shirts and one pair of shoes.If the sales tax is 8% how much will devin pay for his ourchase
Answer:
$65.88
Step-by-step explanation:
Given data
Sales Tax= 8%
Cost of shirt= $36
Cost of shoe= $25
Total cost= 36+25
Total=$61
Let us find the amount of the Tax
=8/100*61
=0.08*61
=$4.88
Hence the amount paid is
=61+4.88
=$65.88
Find the 8th Term for the Geometric Sequence for which a1 - 3 and r = -2
Answer:
-384
Step-by-step explanation:
geometric sequence : every new element is generated by multiplying the previous element always with the same number r.
a(n) = a(n-1) * r
a(n) = a(1) * r^(n-1)
so, a(1) = 3, r = -2
a(8) = ?
a(8) = a(1) * r^7 = 3 * (-2)^7
a negative number to an uneven power is again a negative number.
so, (-2)^7 = -128
3 * -128 = -384 = a(8)
Solve for y:
x + 2y = -8
y=-1/2x+4
y=-1/2x-4
y=-2x - 4
y=1/2x-4
Answer:
x + 2y = -8 = y = -4 - 1/2x
y= -1/2x + 4 = y = 4
y= -1/2x - 4 = y = -4
y=-2x - 4 = y = -4
y=1/2x-4 = y = -4
Step-by-step explanation:
(x + 2y = -8 = y = -4 - 1/2x)
[tex]x+2y=-8\\2y=-8-x\\y=-4-\frac{1}{2}x\\[/tex]

Kalo randomly surveyed 25 students at his school and found that 19 of them have at least one sibling. Based on these data, how many of the 125 students at his
school would be expected to have at least one sibling?
Answer:
95 students
Step-by-step explanation:
25 students -- 19 have sibling
1 student -- (19/25)
125 students -- (19/25) * 125 = 95
Therefore, 95 students out of 125 are expected to have at least one sibling.
Thenks and mark me brainliest :))
Answer:
95
Step-by-step explanation:
Calculate the experimental probability of choosing a student who has at least one sibling: It is 19/25, or 0.56.
If 125 students are selected, this probability applies. Multiply 125 by 0.56:
0.56(125 students) = 95
95 students could be expected to report having at least one sibling.

At a location 30m from the base of a flagpole, the angle of elevation is 34 degrees. Determine the height of the flagpole to the nearest meter.
Answer:
20.2 m
Step-by-step explanation:
At a location 30m from the base of a flagpole, the angle of elevation is 34 degrees. Determine the height of the flagpole to the nearest meter.
We solve this question using the Trigonometric function of Tangent
tan θ = Opposite/Adjacent
θ = 34°
Adjacent =30m
Opposite = Height of the flag pole = x
Hence
tan 34 = x/30
Cross Multiply
tan 34 × 30m
= 20.235255505 m
Approximately = 20.2 m
Hence, the height of the flag pole to the nearest meter = 20.2m
