3x-y= 17
-x+y= -7
Help please
Answer:
y = -2
x = 5
Step-by-step explanation:
3x - y = 17
-x + y = -7
here we can find the sum of the two equations
2x = 10
x = 5
now we can just plug in the value of x to find y
-(5) + y = -7
y = -2

What is a translation?A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.
The function f(x) = tan(x + 1) is a translation of one unit to the left of g(x) = tan(x), which has g(0) = 0, hence at the translated function g(-1) = 0, which means that graph D represents the function f(x).

Type your numerical answer below (without units). If necessary, round to the nearest whole number.
Answer:
83 m
Step-by-step explanation:
The missing dimension can be found by using the area formula. Fill in the given values, and solve for the remaining unknown value.
__
A = LW . . . . . area of a rectangle of length L and width W
3403 m² = L(41 m) . . . . with given values filled in

Find the mean, median, mode, and range of the following data with and without outliers.
110, 64, 23, 95, 86, 17, 23, 100, 95, 67
HELP. td is the last day to finish hmw and I'm behind :,)
Answer:
mean: 68
median: 76.5
mode: 23, 95
range: 93
Step-by-step explanation:
Put numbers in order:
17, 23, 23, 64, 67, 86, 95, 95, 100, 110
mean: sum of the terms / number of terms
sum of the terms: 17 + 23 + 23 + 64 + 67 + 86 + 95 + 95 + 100 + 110 = 680
number of terms: 10
680 / 10 = 68
median: number of terms / 2
10 / 2 = 5, 5th number on the list
17, 23, 23, 64, 67, 86, 95, 95, 100, 110
between 67 and 86 since its an even number data set
67 + 86 / 2 = 76.5
mode: the most occurring number
17, 23, 23, 64, 67, 86, 95, 95, 100, 110
- 17, 64, 67, 86, 100, 110 has 1 each
- 23 has 2
- 95 has 2
23 and 95 have the same reoccurring amount
range: max - min numbers
17, 23, 23, 64, 67, 86, 95, 95, 100, 110
110 - 17 = 93
NO outliers
Hope this helps you a little more for your last day of finishing hmw :)

Sam is using the expression 2x/6y in class. What is the value of the expression when... x=15 and y= 1/3?
Answer:
the value of the expression will be 15.
Step-by-step explanation:
equation giver : 2x/6y
value of x given: 15
value of y given: 1/3
on putting the values in the equation,
2×15 / 6×1/3
= 30 / 6/3
on simplification,
= 30/2
= 15
therefore, the value of the expression will be 15

The probability of the sample having a mean gas mileage between 27 and 29 miles per gallon will be 0.0116.
What is a normal distribution?The Gaussian Distribution is another name for it. The most significant continuous probability distribution is this one. Because the curve resembles a bell, it is also known as a bell curve.
The z-score is a statistical evaluation of a value's correlation to the mean of a collection of values, expressed in terms of standard deviation.
In 2014, new cars had an average fuel efficiency of 27.9 miles per gallon with a standard deviation of 6.8 miles per gallon. a sample of 30 new cars is taken.
Then the probability the sample has a mean gas mileage between 27 and 29 miles per gallon will be
The value of the z-score at x = 27, we have
[tex]z = \dfrac{27 - 27.9}{6.8}\\\\z = -0.13[/tex]
The value of the z-score at x = 29, we have
[tex]z = \dfrac{29 - 27.9}{6.8}\\\\z = 0.16[/tex]
Then the probability will be
[tex]\begin{aligned} P(-0.13 < z < 0.16 ) &= P (z < 0.16) - P(z > -0.13) \\\\&= P (z < 0.16) - [ 1 - P(z < -0.13) ]\\\\&= 0.56425 - (1 -0.44735)\\\\&= 0.0116 \end[/tex]

The perimeter of an isosceles triangle is 4 times the length of the shortest side. The longer sides are 4.5 ft longer than the shortest side. What is the length of each side of the triangle?
Answer:
Shorter side = 9 feetLonger sides = 13.5 feetStep-by-step explanation:
Let :
Shorter side = xLonger sides = x + 4.5Perimeter = 4xSolving
2(x + 4.5) + x = 4x2x + 9 + x = 4xx = 9 feetSolution
Shorter side = 9 feetLonger sides = 13.5 feetAnswer:
short side: 9 ftlonger sides: 13.5 ftStep-by-step explanation:
The given information lets us write two equations relating the side lengths.
__
setupLet L and S represent the lengths of the longer and shorter sides. We are told ...
S + L + L = 4S . . . . . the perimeter is 4 times the short side length
L = 4.5 +S
__
solutionUsing the second equation to substitute for L in the first equation, we have ...
S +2(4.5 +S) = 4S
9 = S . . . . . . . . . . . . . simplify, subtract 3S
L = 4.5 +S = 13.5
The shortest side is 9 ft; the longer sides are 13.5 ft.

Step-by-step explanation:
Rowan bought a bag of jelly beans that
contained 54 ounces of jelly beans. She
divided the jelly beans into bags that
contained 6.75 ounces each. Write a division
equation that could be used to find the
number of bags she made.
Answer:
[tex]\sf y=\dfrac{54}{6.75}[/tex] or [tex]\sf y=54 \div 6.75[/tex]
(where y is the number of bags made)
Step-by-step explanation:
If Rowan bought a 54 oz bag of jelly beans and divided them into bags that each contained 6.75 oz, to find how many bags were made, divide the total weight of jelly beans by the weight of each bag.
⇒ Number of bags = Total weight ÷ bag weight
= 54 ÷ 6.75
= 8
Therefore, Rowen made 8 bags.
Total weight of jelly beans initially
54ozEach bag contains
6.75ozSo the equation should be
Bags=54/6.75Or
B=54/6.75If we solve we get total bags as 8

State if the three numbers can be the measures of the sides of a triangle. 11, 3, 8
we have three sides, let's look at the two smaller sides first.
check the picture below atop.
if we move the sides closer and ever closer to each other, to the extent that one is right on top of the other, what is the length of the red side? Well, assuming the two smaller sides are one pancaked on top of the other, the red side will be as long as 8 - 3 = 5. However, the sides can't be on top of each other, because if that's so, we have a flat-line, and thus we wouldn't have a triangle. So whatever the third side may be, it must be greater than 5.
check the picture below at the bottom
Now, if we move the sides away from each other, farther and farther to the extent that one is parallel to the other, then the third side will just be as long as 3 + 8 = 11. However, we can't do that, because if that were to happen, we again will have a flat-line and not a triangle. So whatever the third side may be, it must be less than 11.
so the third side being 11 is a no dice.
