Answer:

h(t) = -3 + 1.5t

Step-by-step explanation:

Well, the temperature starts at -3, so that will be the y intercept. 1.5 is the rate, so that will be the slope.

h(t) = -3 + 1.5t

Answer:

let x stand for number of weeks

135+15x>=480

x>=23

Step-by-step explanation:

subtract 135 on both sides

15x>=345

divide by 15 on both sides

x>=23 is your solution

x* 2½ = 15/16

x * 5/2 = 15/16

x = 15/16*2/5

Answer:

Step-by-step explanation:

Answer:

(-3, 4)

Step-by-step explanation:

5(7x - 2y = -29)

35x - 10y = -145

9x + 10y = 13

44x = -132

x = -3

7(-3) - 2y = -29

-21 - 2y = -29

-2y = -8

y = 4

m=3-1/3+2=2/5

Equation of line in point slope. form

[tex]\\ \sf\longmapsto y-y_1=m(x-x_1)[/tex]

[tex]\\ \sf\longmapsto y-1=2/5(x-(-2))[/tex]

[tex]\\ \sf\longmapsto y-1=2/5(x+2)[/tex]

[tex]\\ \sf\longmapsto 5y-5=2x+4[/tex]

[tex]\\ \sf\longmapsto 2x-5y+9=0[/tex]

The equation of the line is y = (2/5)x - 1/5 which passes through the points (-2, 1) and (3, 3).

The slope of a line is defined as the angle of the line.

Given that line passes through the points (-2, 1) and (3, 3)

Let the required line would be y - y₁ = (y₂ - y₁)/(x₂ -x₁ )[x -x₁]

x₁ = -2, y₁ = 1

x₂ = 3, y₂ = 3

⇒ y - y₁ = (y₂ - y₁)/(x₂ -x₁ )[x -x₁]

Substitute values in the equation, we get

⇒ y - 1 = (3 - 1)/(3-(-2))[x -(-2)]

⇒ y - 1 = (2)/(5)[x+2]

⇒ y - 1 = 2/5(x -3)

⇒ y = (2/5)x - 6/5 + 1

⇒ y = (2/5)x - 1/5

Therefore, the equation of the line is y = (2/5)x - 1/5 which passes through the points (-2, 1) and (3, 3).

Answer:

look at the picture i have sent

Answer:

I believe the answer is 20 cds

Step-by-step explanation:

got Ben to have twice her CDs he would have to have 24 while she had 12.

if Ali gave away 40 percent than 12 would be 60 percent.

from there I cross multiplied.

If the total number of CDs is 36, it is not possible to distribute them in a way that Ben receives twice as many as Ali after Ali gives away 40% of her CDs.

Let's assume the number of CDs Ali originally had is "x," and the number of CDs Ben originally had is "y."

According to the information given:

1. Ali and Ben have a total of 36 CDs: x + y = 36

2. After Ali gives Ben 40% of her CDs, Ben has twice as many as Ali:

Ali gives away 40% of x, which is 0.4x CDs.

After this, Ali has x - 0.4x = 0.6x CDs left.

Ben receives 0.4x CDs from Ali and now has y + 0.4x CDs.

According to the second statement, y + 0.4x = 2(0.6x).

Now, we have a system of two equations:

x + y = 36 ........(1)

y + 0.4x = 2(0.6x) ........(2)

First, let's simplify equation (2):

y + 0.4x = 2(0.6x)

y + 0.4x = 1.2x

Now, to solve for x, isolate y in equation (1) and substitute it into equation (2):

y = 36 - x

Substitute y in equation (2):

36 - x + 0.4x = 1.2x

Combine like terms:

36 = 1.2x + x - 0.4x

36 = 1.6x

Now, solve for x:

x = 36 / 1.6

x = 22.5

Since the number of CDs cannot be a decimal, let's reevaluate the equations.

From equation (1):

x + y = 36

Substitute the value of x we found:

22.5 + y = 36

y = 36 - 22.5

y = 13.5

Now, we have found that Ali originally had 22.5 CDs, which is not possible. However, since the number of CDs must be a whole number, it means there might be a mistake in the problem statement.

Answer:

116

Step-by-step explanation:

First, find x. The three angles of any triangle will always equal 180, so set up an equation like this:

(14x+4)+(5x-1)+(2x+9)=180

x=8

Then to find angle A put 8 in place of x. 14(8)+4=116

Answer:

[tex]116 \degree[/tex]

Step-by-step explanation:

Interior angles of a triangle is added up to 180°

Therefore,

[tex]14 x + 4 + 5x - 1 + 2x + 9 = 180 \degree\\ [/tex]

Now you can solve this equation and find the value of x

[tex]14 x + 4 + 5x - 1 + 2x + 9 = 180 \degree \\ 14x + 5x + 2x + 4 - 1 + 9 = 180 \\ 21x + 12 = 180 \\ 21x = 180 - 12 \\ 21x = 168 \\ \frac{21x}{21} = \frac{168}{21} \\ x = 8[/tex]

Now you can Find the value of <A

[tex]14x + 4 \\ 14 \times 8 + 4 \\ 112 + 4 \\ = 116 \degree[/tex]

Answer:

A: (x = 34, y = -27, z = -1)

Step-by-step explanation:

Plug the variables in. It might be tedious, but it guarantees you get it right.

Let's try A first. 2(34) + 2(-27) + 6(-1) = 8. Is this correct? Yes. However, you gotta plug it in for the other three equations. 5(34) + 6(-27) + 5(-1) = 3. Is this correct? Yes again. One last equation. 5(34) + 6(-27) + 3(-1) = 5. That's correct as well. The answer is A.

In case you still weren't sure if the answer was A or not;

B: 2(33) + 2(-26) + 6(0) = 14. Right away we can see that B will be incorrect.

C: 2(35) + 2(-28) + 6(-2) = 2. Again, incorrect.

D: 2(36) + 2(-29) + 6(1) = 20. Incorrect!

A is the correct answer.
