−2x+5y=−17 3x-10y=283x−10y=28

Answers

Answer:

x = 6

y = -1

Step-by-step explanation:

-2x + 5y = -17 ------ equation 1

3x- 10y = 28 ------- equation 2

equation 1× 2

-4x + 10y = -34 ------- equation 3

equation 2 + equation 3

-x = -6

x = 6

x = 6 substitute for equation 1

Answer:

I think the answers are E = 4 ¼ F = -6 ¼ D = -3 ¼

How do you answer this?

Answers

Answer:

x= -3/2

Step-by-step explanation:

((4)²)^x = 1/(4)³

4²^x = 4³

thus the powers are same then

2x =-3

x=-3/2

Answer:

x = - [tex]\frac{3}{2}[/tex]

Step-by-step explanation:

Using the rules of exponents

[tex](a^m)^{n}[/tex] = [tex]a^{mn}[/tex]

[tex]a^{-m}[/tex] ⇔ [tex]\frac{1}{a^m}[/tex]

Note that 16 = 4² and 64 = 4³ , then

[tex]16^{x}[/tex] = [tex]\frac{1}{64}[/tex] , can be expressed as

[tex](4^2)^{x}[/tex] = [tex]\frac{1}{4^3}[/tex] , that is

[tex]4^{2x}[/tex] = [tex]4^{-3}[/tex]

Since the bases on both sides are equal, then equate the exponents

2x = - 3 ( divide both sides by 2 )

x = - [tex]\frac{3}{2}[/tex]

Aaron, Darren, Karen, Maren, and Sharon rode on a small train that has five cars that seat one person each. Maren sat in the last car. Aaron sat directly behind Sharon. Darren sat in one of the cars in front of Aaron. At least one person sat between Karen and Darren. Who sat in the middle car?

Answers

Answer:

Sharon

Step-by-step explanation:

The given parameters are;

The number of persons that rode on the small train = 5

The number of cars in the train = 5

The position Maren sat = Last car

The position Aaron sat = Directly behind Sharon

The position Darren sat = In one of the cars in front of Aaron

The position of one of the members = Between Karen and Darren

The given seating arrangement is as follows;

Maren → Aaron → Sharon → Darren → Karen

Therefore, the person who sat in the middle car is Sharon.

what is the equation of the line in slope intercept form

Answers

Answer:

y=x-70

Step-by-step explanation:

Y= x-70 is correct.
To write an equation in slope-intercept form, given a graph of that equation, pick two points on the line and use them to find the slope. This is the value of m in the equation. Next, find the coordinates of the y-intercept--this should be of the form (0, b). The y- coordinate is the value of b in the equation.

Answers

Answer:

1. Vanilla

2.Strawberry

3.Chocolate

4.CS

5.VV

6.SS

Step-by-step explanation:

For these problem you are solving to find ALL of the possible outcomes with the 3 flavours.

1. They already have a combination for Chocolate-chocolate and Chocolate-Strawberry. The only flavour you haven't used yet is vanilla which makes your first answer vanilla.

2. They already have a combination for Vanilla-Chocolate and Vanilla-Vanilla. The only flavour you haven't used yet is Strawberry which makes your answer strawberry.

3. They already have a combination for Strawberry-Vanilla and Strawberry-Strawberry. The only flavour you haven't used yet is chocolate which makes your answer chocolate.

So when looking at the letters they are honestly just initials to the combinations possible. The order of the letters depend on what words come first going down your branch.

4. The two words are chocolate and strawberry. The first letter in both words are C and S so the answer is CS.

5. The two words are vanilla and vanilla. The first letter in both words are V and V so the answer is VV.

6. The two words are strawberry and strawberry. The first letter in both words are S and S so the answer is SS.

Due to a bad crop year, the cost of cherries is projected to increase 133% this year. A pound of cherries currently costs $2.16. What can you expect the new price per pound to be?

Answers

To solve this problem, or one of sorts, you can multiply the current price (2.16) by 1.33 (the percentage as a decimal).

2.16*1.33 = 2.8728

Round to two decimal places (and that’s the number of decimal places for money), and you can expect the new price per pound of cherries to be about $2.87.
