Answer:
y = -1/3
Step-by-step explanation:
Isosceles trapezoids have legs that are the same length
AB = CD
7y-4 = 4y-5
Subtract 4y from each side
7y-4-4y = 4y-5-4y
3y -4 = -5
Add 4 to each side
3y -4+4 = -5+4
3y = -1
Divide by 3
3y/3 = -1/3
y = -1/3
Step-by-step explanation:
an isoceles trapezoid means that both legs (the sides left and right) are of equal length.
the length of the baseline does not matter at all (I guess, it is given here to confuse us or for follow up questions).
so, we know that AB = CD.
and therefore
7y - 4 = 8y - 18
-4 = y - 18
14 = y

a grocer has to sell two kinds of candy, one selling for 40 cents a pound and the other for $1.40 per pound. how many pounds of each kind must he use to make 100 pounds worth 85 cents a pound
Answer:
$1.40 candy: 45 pounds$0.40 candy: 55 poundsStep-by-step explanation:
Let x represent the number of pounds of the more expensive candy. Then the price of the mix is ...
1.40x +0.40(100 -x) = 0.85(100)
x +40 = 85 . . . . . . simplify
x = 45 . . . . . . . . subtract 40
100 -x = 55 . . . pounds of cheaper candy
The grocer must use 45 pounds of $1.40 candy and 55 pounds of $0.40 candy to make the mix.

Answer:
[tex]y=1/4+1\\[/tex]
Step-by-step explanation:
There are a few ways to do this.
1) Make a graph
You can graph [tex]y=1/4x[/tex] by placing a dot 1 y-value above every time you go four x-values to the left. Place (4,2) on the graph and plug in different values of b.
2) Make and solve an equation
Our equation will use the point given to us, and the slope
Since 2 = y and 4 = 2, we will plug those in for [tex]y=mx+b\\[/tex]
[tex]2=1/4(4)+b\\2=1+b\\1=b[/tex]
Therefore, the equation for this question is [tex]y=1/4x+1[/tex]
How do I remove the 1 on the numerator when solving for x
1/x = 5
Answer:
x = [tex]\frac{1}{5}[/tex]
Step-by-step explanation:
[tex]\frac{1}{x}[/tex] = 5 ( multiply both sides by x to clear the fraction )
1 = 5x ( divide both sides by 5 )
[tex]\frac{1}{5}[/tex] = x
Use the table to write a linear function that relates y to x

Answer:
30 + 5y
Step-by-step explanation:
Distribute the 5
5*6 = 30
5*y = 5y
and add
Answer:
[tex]5y+30[/tex]
Step-by-step explanation:
This equation on the left wants us to use the distributive property. That means we can distribute 5 to the 6, and the y in the equation. So, we will multiply.
[tex]5(6)=30\\5(y)=5y[/tex]
And, it wants us to add the two, so therefore it would be [tex]5y+30[/tex]

A company logo is made up of a square and four identical triangles, as shown in this image
What is the area of the logo
Enter your answer in the box
Answer:
Area is 72cm²
Step-by-step explanation:
Data :
There are four triangles and a square
x = 6 cm
h = 3 cm
Formula for square
Area = A = x² = 6² = 36
All triangles has equal area
So formula used to find area is
Area = A = 1/2 bh = 1/2 × 6 × 3 = 9
For four triangles
9 × 4 = 36
Add them
36 + 36 = 72
Answer:
91
Step-by-step explanation:
the real answer is 91 its not 72 I took the test k12
A cube with sides 5 inches, and a pyramid with base edges 5 inches. What is the height, so that the volume of the cube and the pyramid are equal?
15 inches is the height of the pyramid
Step-by-step explanation:
The volume of a cube is a³
Given a = 5 inches
→ Volume = a³
= 5³
= 5×5×5
= 125 in²
The volume of a pyramid is [tex] \frac{1}{3} {a}^{2}h[/tex]
Given a = 5 inches , h = height of pyramid
[tex] = > \frac{1}{3} {a}^{2} h[/tex]
[tex] = > \frac{1}{3}(5)^{2}h[/tex]
[tex] = > \frac{1}{3} \times 25 \times h[/tex]
[tex] = > \frac{25}{3}h[/tex]
then,
[tex]125 = \frac{25h}{3}[/tex]
[tex] = > 25h = 125 \times 3[/tex]
[tex] = > 25h = 375[/tex]
[tex] = > h = \frac{375}{25} [/tex]
[tex] = > h = 15[/tex]
Hence, the height of pyramid is 15 inches

Answer:
D. 17,15,13,11
Step-by-step explanation:
The expression states that the next term in this sequence is formed by subtracting 2 from the preceding (n-1) result. We know that for n = 1 that f(1) = 17.
f(n) is f(n-1) - 2
so
f(2) = f(1) - 2
f(2) = 17 - 2 or 15
f(3) = f(2) - 2
f(3) = 15 - 2 or 13
f(4) = f(3) - 2
f(4) = 13 - 2 or 11
. . . .
. . . .
. . . .
and so on.
Answer:
D and B
Step-by-step explanation:
using the recursive formula and f(1) = 17 , then
f(2) = f(1) - 2 = 17 - 2 = 15
f(3) = f(2) - 2 = 15 - 2 = 13
f(4) = f(3) - 2 = 13 - 2 = 11
first 4 terms are 17, 15, 13, 11 → D
-------------------------------------------------------
Using the recursive formula and f(1) = 5 , then
f(2) = 4f(1) = 4 × 5 = 20
f(3) = 4f(2) = 4 × 20 = 80
f(4) = 4f(3) = 4 × 80 = 320
first 4 terms are 5, 20, 80, 320 → B

Loren is making a holiday pack for her customers. She has 5 different designs and 6 different greeting texts. Each holiday pack includes 3 different designs and 2 different texts. How many unique packs can she create?
Answer: 1
Step-by-step explanation: only 1 because since each include only 3 diff designs, and she currently owns 5 diff designs, and you can exactly go any further, because 3 + 3 = 6, and its only 5. If it werent for the designs, then she could make 3 texts, because 2 x 3 = 6. Sorry if I got it wrong, I'm just confused on how this is explained.
150 unique packs can be created.
What is Combination?Combinations are mathematical operations that count the number of potential configurations for a set of elements when the order of the selection is irrelevant. You can choose the components of combos in any order. Permutations and combinations can be mixed up.
Given:
Loren has 5 different designs and 6 different greeting texts.
Each holiday pack includes 3 different designs and 2 different texts.
So, the unique ways to create
= [tex]^5C_3 . ^6C_2[/tex]
= 5! / 3! 2! x 6! / 2! 4!
= 10 x 15
= 150
Hence, 150 unique packs can be created.

Find the 88th term of the arithmetic sequence 4, -1, -6, ...4,−1,−6,...
Answer:
88th term = -431
to solve, keep subtracting 5
Answer:
a₈₈ = - 431
Step-by-step explanation:
The nth term of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
here a₁ = 4 and d = a₂ - a₁ = - 1 - 4 = - 5 , then
a₈₈ = 4 + (87 × - 5) = 4 + (- 435) = 4 - 435 = - 431

Step-by-step explanation:
Solve each system of equations using the elimination method
3x+8y=2
4x-2y=-10
x = -2
y = 1
let's multiply second equation by 4 to get a common coefficient of y variable.
16x-8y=-40
add the equations
3×+8y=2
16x-8y=-40
----------------
3x+16x = -38
19x = -38
x = -2
substitute x
3×-2 + 8y = 2
-6 + 8y = 2
8y = 2+6
y = 1
check the answer
-6+8 = 2

Which statement is true about the effects of the transformations on the graph of function f to obtain the graph of function g.
g(x) = f(x) + 4
A.
The graph of function f is shifted up 4 units.
B.
The graph of function f is compressed vertically toward the x-axis by a factor of 4.
C.
The graph of function f is stretched vertically away from the x-axis by a factor of 4.
D.
The graph of function f is shifted down 4 units.
Answer:
A
Step-by-step explanation:
The constant 4 is positive so the graph is shifted up by 4 units. If it was instead -4, then the graph would have been shifted down 4 units
