Your teacher is giving you a test worth 100 points containing 40 questions. There are two-point questions (x) and four-point questions (y). How many of each type of question are on the test?

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

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

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.

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.

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

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]

Answer:

  -101

Step-by-step explanation:

Put 9 where x is, and do the arithmetic.

  f(x) = -x² -20

  f(9) = -9² -20 = -81 -20

  f(9) = -101

Answer:

4 units to the right

Step-by-step explanation:

A(-1,4) is translated into A'(3,4)

so this point was shifted four to the right because only the x- value was changed

Answer: 50

Let's first of all assume the son's age as x.

So,

Father's age will be 2x i.e. twice as old as the son

Given that,

Sum of their ages = 75 years

So,

x + 2x = 75

3x = 75

x = 75/3

x = 25

Hence,

Son's age = x = 25 years

Father's age = 2x = 2 * 25 = 50 years

For the first box, we add the two values 90 and 150 to get 240.

The same goes for the second box as well, except we cannot combine n and p together. We leave it as n+p. If we knew what numbers replaced n and p, then we could simplify further.

from any given point you go up 1 and over to the RIGHT 3 (1/3)

or you can go down one and to the LEFT 3 (-1/-3)

y intercept is -2 so you have y = 1/3x - 2

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]

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:

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
