~AH1807Peace!let f(x)=2x-1 and g(x)=1/x. Find the value of f(g(7))
Answer:
-5/7
Step-by-step explanation:
We need to find g(7) first
All we have to is plug 7 in the place of x
g(7) = 1/7
Now we have f(1/7) = 2x - 1
f(1/7) = 2(1/7) - 1
f(1/7) = 2/7 - 1
Don't forget about common denominators
2/7 - 7/7 = -5/7

will it take 10 men to paint 8 such houses?
Plz help I’ll mark brainliest
Answer:
6 days
Step-by-step explanation:
If you like my answer than please mark me brainliest thanks
Answer:6 days
Step-by-step explanation:
because it means 5 men painted 1 house in 1.5days(3:2=1,5), so for 5 men to paint 8 houses they will need 12 days (1.5x8=12) divide 12 in half because there will be twice as much men(10) and you get 6 days

OD. 39
Answer: A. 32
Concept:
Here, we need to know the idea of the intersecting chord theorem and segment addition postulate.
The intersecting chord theorem states that when two chords intersect at a point, P, the product of their respective partial segments is equal.
The Segment Addition Postulate states that given 2 points A and C, a third point B lies on the line segment AC if and only if the distances between the points satisfy the equation AB + BC = AC.
If you are still confused, please refer to the attachment below for a graphical explanation.
Solve:
Given information
CW = 12
TW = 14
VW = 2x + 5
UW = 2x + 2
Given expression deducted from intersecting chord theorem
CW · VW = TW · UW
Substitute values into the expression
(12) · (2x + 5) = (14) · (2x + 2)
Expand parentheses and apply the distributive property
24x + 60 = 28x + 28
Subtract 14x on both sides
24x + 60 - 24x = 28x + 28 - 24x
60 = 4x + 28
Subtract 28 on both sides
60 - 28 = 4x + 28 - 28
32 = 4x
Divide 4 on both sides
32 / 4 = 4x / 4
x = 8
Given expression deducted from the segment addition postulate
UT = UW + TW
Substitute values into the expression
UT = 2x + 2 + 14
Substitute x value into the expression
UT = 2 (8) + 2 + 14
UT = 16 + 2 + 14
Combine like terms
UT = 32

18. Solve x^2+ 6x - 16 = 0 by completing the square.
Please give detailed steps!!
Answer:
x1 = -8, x2= 2
Step-by-step explanation:
1. Write 6x as a difference
= x^2 + 8x - 2x - 16 = 0
2. Factor the expressions
= x ( x + 8 ) - 2x - 16 = 0
= x ( x + 8 ) - 2 ( x + 8 ) = 0
Factor out x + 8 from the expression
= ( x + 8 ) ( x - 2 ) = 0
3. When the product of factors = 0, at least one factor is 0
x + 8 = 0
x - 2 = 0
4. Solve the equation for x
x = - 8
x = 2
Therefore, the equation has 2 solutions :
x1 = -8, x2 = 2

Answer: 27
Step-by-step explanation: hihihihihiiiiihihi
27 is considered an outlier for the data set.
What is quartiles?In statistics, a quartile exists as a variety of quantiles which divides the number of data points into four parts, or quarters, of more or less equal size. The data must be ordered from smallest to largest to calculate quartiles; as such, quartiles exist a form of order statistic.
A quartile separates data into three points—a lower quartile, median, and upper quartile—to form four sets of the dataset.
Hence, 27 is considered an outlier for the data set.
