Answer:
a = 8
Step-by-step explanation:
a + 7 = 15
a + 7 - 7 = 15 - 7 Subtract 7 from both sides.
a = 8
Answer is
A = 8
Because 8 + 7 = 15
The other way to explain we need to subtract 7 ( 7 -7 = 0 and 15 - 7 = 8 ) both sides so after subtracting you will get 8

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]

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

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

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

Solve for k in the following equation: E = 2kn
Answer:
(E/2)/n = k
So when doing this you have to isolate K since your solving for “k”.
In order to do this you have to perform the inverse of every variable or number in order to isolate K.
In this case you divide 2 and then N.
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
Kathrine makes bracelets at a rate represented by a algebraic equation y=4× where x is the number of days, and y is the total number of bracelets made. Katherine also makes necklaces at the rate shown in the graph. How many more days will it take katherine to make 20 necklaces than it will take her to make 20 bracelets?
Using the algebraic equation and the graph given, number of extra days it will take Kathrine to make 20 necklaces than it will take her to make 20 bracelets is: 8 - 5 = 3 days.
What is an Algebraic Equation?An algebraic equation, like the one given, models word problems, and can be used to find unknown numbers.
Thus:
y = 4× represents the rate Kathrine uses to make bracelets, where,
x = number of days
y = total number of bracelets made
Find the number of days (x) it takes to make 20 bracelets.
Substitute y = 20 into y = 4x:
20 = 4x
20/4 = x
x = 5 days.
Create an algebraic equation in the form of, y = kx, for the rate of necklace Kathrine makes using the graph.
Thus, using the point, (4, 10), substitute x = 4 and y = 10 into y = kx and find k.
10 = k(4)
10/4 = k
k = 2.5
The algebraic equation for rate of necklace made is: y = 2.5x
Number of days Kathrine will use to make 20 necklaces would be:
20 = 2.5x
20/2.5 = x
x = 8 days.
Number of days to make 20 bracelets = 5 days
Number of days to make 20 necklaces = 8 days
In summary, using the algebraic equation and the graph given, number of extra days it will take Kathrine to make 20 necklaces than it will take her to make 20 bracelets is: 8 - 5 = 3 days.
