On Tuesday, Marissa was $45 short of her fundraising goal. The next day, she was $5 over her goal write an equation to show how much she raised in one day.

Answers

Answer 1

Answer: Hello daema, let's let x be the goal and c be the collection per day.

x - 45 + c = x + 5 is the answer so now let's talk about how we did that.

So she wants to get to x which is the goal. But right now she has 45 less than what her goal is. So that would look like this x - 45 now she has to get c or the collection per day to get to her goal. So now it looks like this x - 45 + c. Now that c has to be at least x which is her goal, it now will look like this x - 45 + c = x. But we're not done, the question said that now she 5$ over her goal, or x. So we have to add the + 5 onto the end so now it looks like this x - 45 + c = x + 5. To solve the equation "if you have to" it would be x = 50$ per day.

Greg went to the store. He bought 5 kilograms of purple beads, 1/2 of a kilogram of orange beads, and 2 kilograms of white beads. How much did he spend?

Answers

Answer:

Altogether, Greg spent $22.71.

Step-by-step explanation:

1) 5kg × $2.75 = $13.75

Purple beads: Spent $13.75

2) 1/2 kg = 1.5kg

1.5kg × $1.84 = $2.76

Orange beads: Spent $2.76

3) 2kg × $3.10 = $6.20

White beads: Spent $6.20

4) Add them all together.

$13.75 + $2.76 + $6.20 = $22.71

Find an explicit formula for the geometric sequence -40,-20,-10......
Note: the first term should be c(1).

c(n)= ?

Answers

Answer:

The explicit formula for the geometric sequence is [tex]c(n) = -40\cdot \left(\frac{1}{2} \right)^{n-1}[/tex].

Step-by-step explanation:

By definition of geometric sequence, we should use the following expression:

[tex]c(n) = c_{1}\cdot r^{n-1}[/tex], [tex]n \ge 1[/tex] (1)

Where:

[tex]c_{1}[/tex] - First term.

[tex]r[/tex] - Geometric rate.

[tex]n[/tex] - Position of the element within the series.

If we know that [tex]c_{1} = -40[/tex] and [tex]r = \frac{1}{2}[/tex], then the explicit formula for the geometric sequence is:

[tex]c(n) = -40\cdot \left(\frac{1}{2} \right)^{n-1}[/tex]

The explicit formula for the geometric sequence is [tex]c(n) = -40\cdot \left(\frac{1}{2} \right)^{n-1}[/tex].

1) What is the product of (3​x +​ 2) and (​x -​ 7)?
2) What are the factors (multiplier) of 3x2 − 9x ?

Answer both of the questions

Answers

Answer:

1) [tex]3x^{2}[/tex]-19x-14

2) x=0, x=3

Step-by-step explanation:

1) (3x+2)(x-7)

Distribute the 3x to both x and -7, as well as the 2 to both x and - 7.

[tex]3x^{2}[/tex] - 21x + 2x -14

Combine like terms

[tex]3x^{2}[/tex] - 19x - 14

2)

In order to find the factors of x, set the expression equal to 0.

[tex]3x^{2}[/tex] - 9x = 0

Factor out the highest common multiple (3x)

3x(x-3) = 0

In order for x to satisfy the equality, you must either have a 0 in the parenthesis -> (x-3)=0 -> x =3

Or 3x = 0 -> x = 0

Number of Disks in the Tower ║Minimum Number of Moves

1 ║1

2║ 3

3 ║7

4 ║15

Answers

Answer:

[tex]y = 2^x - 1[/tex]

Step-by-step explanation:

Let the number of disks be x and the minimum number of moves be y.

[tex]y = 2^x - 1[/tex]

When x = 1: y = 1

[tex]y = 1 = 2 - 1 = 2^1 - 1[/tex]

When x = 2: y = 3

[tex]y = 3 = 4 - 1 = 2^2 - 1[/tex]

When x = 3: y = 7

[tex]y = 7 = 8 - 1 = 2^3 - 1[/tex]

When x=4: y = 15

[tex]y = 15 = 16 - 1 = 2^4 - 1[/tex]

When x = 5: y = 31

[tex]y = 31 = 32 - 1 = 2^5 - 1[/tex]

Notice that for each derived expression of y, the exponent of 2 is being replaced by the value of x.

The general equation is: [tex]y = 2^x - 1[/tex]

Im not a hundred percent sure if this is the right answer but im pretty sure it is 3.33333 repeated so the rate of change is 3 inches per week.

Step-by-step explanation:

I calculated the problem by subtracting the weeks from each other subtracting the amount of length corn has grown too. I found that the corn grew 40 inches in 12 weeks. So I divided the amount of weeks and the amount it has grown and it gave me 3.333333 repeated which makes the answer 3 inches per week. correct me if im wrong...

If PQRS is a kite, find m angle Q

Answers

Answer:

Q = 35

Step-by-step explanation:

1. You add both (m)x values and y values making them equal to 180 creating a 2 step-equation: (7x+2) + (10x-31) making that 17x-33= 180

2. Now you have a 2 step-equation to solve: 17x-33 = 180-33=147

                                                                                  +-33  +-33

                                                                                 __________

                                                                              17x = 147/17=21

                                                                               /17     /17

3. From here with 21, knowing the kite must equal to 180, you add 21 to the other angle 124: 124+21=145

4. Seeing that you don't have a total of 180, you now subtract 145 from 180 in order to get the value of Q: 180-145= 35

Q= 35

ΔQ = 78°--------------------------

Step-by-step explanation:

7x + 2 = 10x - 31

33 = 3x

x = 11

so, 7x + 2 = 7( 11 ) +2 = 79°

10x - 31 = 10( 11 ) - 31 = 79°

ΔP + ΔQ + ΔR + ΔS = 360°

79° + ΔQ + 79° + 124° = 360°

ΔQ + 282° = 360°

ΔQ = 360° - 282°

ΔQ = 78°

find the solution by system of equations

Answers

Answer:

x=-2,y=-3

Step-by-step explanation:

x=7+3x

-3x+8y=-18

-21-y=-18

x=7+3x

y=-3

x=7+3x

x=-2

y=-3

Answer:

x = -2

y = -3

Step-by-step explanation:

There are three methods for solving system of equations: elimination, substitution, and graphing. In this case elimination would be the best method since you have -3x for both equations. When solving by elimination, your goal is to eliminate one of the variables, in this case we will eliminate x. Subtract the bottom equation from the top (it is important to remember here that the negative will distribute to the entire equation).

-3х + 9y = -21

- (- 3х +8y = -18)

_____________

y = -3

Now plug this y-value in to either equation and solve for x

-3х + 9y = -21

-3х + 9(-3) = -21

-3x - 27 = -21

-3x = 6

x = -2

Check your answer by plugging both values in to the second equation

- 3х +8y = -18

- 3(-2) +8(-3) = -18

6 - 24 = -18

-18 = -18

which figure is the image of figure 1 after reflection over the y-axis and a translation 3 units down?​

Answers

figure B i imagine is correct

The image of figure 1 after reflection over the y-axis and a translation 3 units down is figure B.

What is the reflection on y-axis?

When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is taken to be the additive inverse. The reflection of point (x, y) across the y-axis is (-x, y).

Coordinates of figure 1 are (-1, 1), (-1, 2), (-2, 2), (-3, 1), (-2, 4) and (-3, 4)

Reflection on y-axis, we get

(1, 1), (1, 2), (2, 2), (3, 1), (2, 4) and (3, 4)

Translation 3 units down

(1, 1-3), (1, 2-3), (2, 2-3), (3, 1-3), (2, 4-3) and (3, 4-3)

(1, -2), (1, -1), (2, -1), (3, -2), (2, 1) and (3, 1)

Figure B has following coordinate points, (1, -2), (1, -1), (2, -1), (3, -2), (2, 1) and (3, 1)

Therefore, the image of figure 1 after reflection over the y-axis and a translation 3 units down is figure B.

x= 3 - 3y

and

x = -24 + 6y

2. set = to each other and solve for y

Solve the equation 17=5k-3

Answers

Answer:

4

Step-by-step explanation:

Simplifying

17 = 5k + -3

Reorder the terms:

17 = -3 + 5k

Solving

17 = -3 + 5k

Solving for variable 'k'.

Move all terms containing k to the left, all other terms to the right.

Add '-5k' to each side of the equation.

17 + -5k = -3 + 5k + -5k

Combine like terms: 5k + -5k = 0

17 + -5k = -3 + 0

17 + -5k = -3

Add '-17' to each side of the equation.

17 + -17 + -5k = -3 + -17

Combine like terms: 17 + -17 = 0

0 + -5k = -3 + -17

-5k = -3 + -17

Combine like terms: -3 + -17 = -20

-5k = -20

Divide each side by '-5'.

k = 4

Simplifying

k = 4

Write the equation of the line that passes through the points (4, -8) and (-8, 1).

What is the association of a graph?A positive association exists when one variable increases as the other variable increases. A negative association exists when one variable increases while the other variable decreases. If there is no relationship between the variables, the scatterplot points have no association.The association is linear when a straight line describes the relationship between the variables. The relationship is monotonic when it is described by a nonlinear function that is constantly increasing or decreasing. Other types of relationships could be nonlinear or non-monotonic.The appropriate statistical measures and tests of association are determined by the type of relationship.A bivariate normal density ellipse summarises the correlation between variables if the relationship is linear. The greater the correlation between the variables, the narrower the ellipse.
