Answer:
EG = 34 FG = 25
Step-by-step explanation:
Answer:
EF = 34
FG = 25
Step-by-step explanation:
We are given that the length of line EG is 59. So we have to first solve for x in order to find the lengths of EF and FG:
(8x - 14) + (4x + 1) = 59
12x - 13 = 59
12x = 72
x = 6
EF:
8x - 14
8(6) - 14
48 - 14
34
FG:
4x + 1
4(6) + 1
24 + 1
25

I need help with #8. I need to use the quadratic formula. I have a calculator that is programmed for the quadratic formula so all I need are the a, b, and c values. for this problem, I am required to show any equations used to solve for the variable. hope you can help me, thanks!!
Answer:
x = 14
Step-by-step explanation:
Extend line AB so that it intersects ray CE at point G. Then angles BGC and BAD are "alternate interior angles", hence congruent.
The angle at B is exterior to triangle BCG, and is equal to the sum of the interior angles at C and G:
138 = (376 -23x) +(x^2 -8x)
Subtracting 138 and collecting terms we have ...
x^2 -31x +238 = 0
For your calculator, a=1, b=-31, c=238.
__
Additional comment
You will find that the solutions to this are x = {14, 17}. You will also find that angle BCE will have corresponding values of 54° and -15°. That is, the solution x=17 is "extraneous." It is a solution to the equation, but not to the problem.
For x=14, the marked angles are A = 84°, C = 54°.
Who can help me find the slope? It’s due soon
The measures of ∠x and ∠y are equal. X is 3(m+2) and Y is 5m-58. Which is the value of m? A m=8 B m=26 C m=30 D m=32
Answer with step-by-step explanation:
M = 32
Step 1: Simplify both sides of the equation.
3(m+2)=5m−58
(3)(m)+(3)(2)=5m+−58(Distribute)
3m+6=5m+−58
3m+6=5m−58
Step 2: Subtract 5m from both sides.
3m+6−5m=5m−58−5m
−2m+6=−58
Step 3: Subtract 6 from both sides.
−2m+6−6=−58−6
−2m=−64
Step 4: Divide both sides by -2.
−2m/−2=−64/−2
m=32

PERIMETER IS ADDING ALL SIDES, AREA IS MULTIPLYING TWO SIDES
1. 2 1/9
2. 42.25
3. 4
4. 87
Answer:
perimeter is adding up all the outside line measures, so for the squares with only one side value, just multiply that by four
the other ones, for the measure given for one side, the opposite side is the same measure, so just add that up.
so number one would be 9 and 1/3 (nine and one third)

Compare solving equations with solving inequalities. How are the processes similar or different?
Answer:
Similarities
1. Adding or subtracting a number from both sides.
2. Multiplying or dividing both sides by a positive number.
3. Applying an increasing function to both sides.
4. Simplifying one or both sides.
Differences
1. Multiplying or dividing both sides by a negative number changes the direction of an inequality. So we cannot multiply or divide both sides by a variable unless we know that the variable is either always positive or always negative. This is not a concern when solving equalities.
2. When applying a decreasing function to both sides of an inequality, the direction of the inequality changes.
3. Swapping both sides of an inequality also changes the direction of an inequality. Again we don't have to worry about this with equalities.
Find three consecutive EVEN integers such that the sum of the smallest number and twice the middle number is 20 more than the largest number.
Answer:
10, 12 and 14Step-by-step explanation:
x - an integer
2x - an even integer (the first and the smaller of the three)
Consecutive integers increase always by 2
2x+2 - next even integer consecutive to 2x (the middle one)
2x+2+2=2x+4 - the last consecutive even integer (the largest)
2•(2x+2) - twice the middle number
2x+2•(2x+2) - the sum of the smallest number and twice the middle one
2x+4+20 - 20 more than the largest number
2x+2•(2x+2) = 2x+4+20
2x + 4x + 4 = 2x + 24
-2x -2x
4x + 4 = 24
÷2 ÷2
2x + 2 = 12 ← the middle number
-2 -2
2x = 10 ← the smallest number
2x+4 = 10 + 4 = 14
Check: 10+2•12=34; 14+20=34

what is the property of equality
Answer: Reflexive property of equality
This property says that any expression is equal to itself.
The reflexive property of congruence is a similar property, but it deals with congruences.
Answer:
The property will equal itself

Let
f(x) = {3x - 7}/{x + 1] Find the range of f.
Give your answer as an interval.
Answer: Range = (-∞, 3) U (3, ∞)
Step-by-step explanation:
The range is the set of all y-values in a function. The easiest and most straightforward way to find the range is to graph the function and find asymptotes, or locations on the graph where the function lacks y-values.
You can plug in a few points to the equation, as shown in this table below.
After you have your points, you can draw your function following the points, as shown in the next image. Notice the line at y = 3, where the function does not cross. Although it will get infinitely close to the line, the function will never meet or cross this point at any x-value. This is what is known as a "horizontal asymptote", and is not included in the range of the function.
We can represent this asymptote in a range, which is a representation of all possible y-values in the function. The possible y-values for this function start at negative infinity and end at infinity, but do not exist at y = 3, so we represent this through this mathematical expression:
Range = (-∞, 3) U (3, ∞)

A spinner with 10 equally sized slices has 2 red slices , and 4 yellow slices, and 4 blue slices. The dial is spun and stops on a slice at random. What is the probability that the dial stops on a red or yellow slice?
Given parameters:
Number of equally sized slices = 10
Red slices = 2
Yellow slices = 4
Blue slices = 4
Unknown:
Probability that the dial stops on a red or yellow color =?
Solution:
Probability is the likelihood of an event to occur.
Probability = [tex]\frac{Possible outcome }{Total outcome}[/tex]
This probability cites a mutually exclusive event because if the dial stops on red, it cannot be on yellow.
Pr(red or yellow) = Pr(red) + Pr(Yellow)
= [tex]\frac{2}{10}[/tex] + [tex]\frac{4}{10}[/tex]
= [tex]\frac{6}{10}[/tex]
= [tex]\frac{3}{5}[/tex]
The probability of red or yellow is [tex]\frac{3}{5}[/tex]
Levi bought 14 chicken wings for $22.40 how much would it cost for 12 wings
Answer:
x =19.20
Step-by-step explanation:
We can use ratios to solve
14 wings 12 wings
------------- = ---------------
22.40 x
Using cross products
14x = 22.40 * 12
14x =268.8
Divide each side by 14
14x/14 = 268.8/14
x =19.20

True or False? In reference to different sampling methods, systematic sampling includes the steps: list the members of the population; use simple random sampling to select a starting point in the population; let k = (number of individuals in the population)/(number of individuals needed in the sample); choose every kth individual in the list starting with the one that was randomly selected.
Answer:
True
Step-by-step explanation:
In the simple random sampling every individual in the population has an equal chance to be selected in the sample. Systematic sampling is a probability sampling in which selection of elements is made from order frame. These samples are selected based on intervals of the population.

kara’s family is thinking about renting a van that can travel 3 3/4 miles on 1/5 gallon of gas. Kara wants to know the gas mileage of the van.
Answer:
[tex] \frac{\frac{1}{5}}{\frac{15}{4}} [/tex]
Step-by-step explanation:
Given:
Miles a van travel = [tex] 3\frac{3}{4} [/tex] miles
Gallons of gas required = [tex] \frac{1}{5} [/tex] gallon of gas
Required:
Unit rate in gallons per mile
SOLUTION:
Unit rate in gallons per mile = (gallons of gas)/miles
Unit rate = [tex] \frac{\frac{1}{5}}{3\frac{3}{4}} [/tex]
Unit rate = [tex] \frac{\frac{1}{5}}{\frac{15}{4}} [/tex]
The fraction that represents the unit rate in gallons per mile = [tex] \frac{\frac{1}{5}}{\frac{15}{4}} [/tex]
Answer:
7/2 and 1/3
Step-by-step explanation:
Look for the fraction that has the number of miles in the numerator and the number of gallons in the denominator
