If y=7.5 when x=0.5, find y when x=-0.3

Answers

Answer 1

Answer: Y= -4.5

7.5/0.5=15

15*(-0.3)= -4.5

-4.5/-0.3=15

Answer 2

Answer:

Final answer:

To find the value of y when x = -0.3, substitute x = -0.3 into the equation and solve for y. The value of y is 3200.

Explanation:

To find the value of y when x = -0.3, we can use the given equation:

Y = 400+ 0.85(Y-0.25Y) + 300 + 200 +500 -0.1(Y-0.25Y)

Substituting x = -0.3 into the equation, we can solve for y.

Y = 400+ 0.85(Y-0.25Y) + 300 + 200 +500 -0.1(Y-0.25Y)
Y = 1400+ 0.6375Y - 0.075Y
0.4375Y = 1400
Y = 3200

Julissa is running a 10-kilometer race at a constant pace. After running for 18 minutes, she completes 2 kilometers. After running for 54 minutes, she completes 6 kilometers. Her trainer writes an equation letting t, the time in minutes, represent the independent variable and k, the number of kilometers, represent the dependent variable. Which equation can be used to represent k, the number of kilometers Julissa runs in t minutes? How does this work i cant really figure it out

Answers

For this case, the first thing we must do is define variables.

We have then:

t: the time in minutes

k: the number of kilometers

The relationship between both variables is direct.

Therefore, the function is:

Where, "c" is a constant of proportionality.

To determine "c" we use the following data:

After running for 18 minutes, she completes 2 kilometers.

Substituting values:

Clearing c we have:

Then, the equation is given by:

Answer:

An equation that can be used to represent k, the number of kilometers Julissa runs in t minutes is:

$k (t) = (1)/(9) * t$

First of all you want to see how long she runs for 1 km and you can figure that out by doing 18/2 and 54/6, they both equal to 9.
So that means that Julissa is running an average of 9 kilometers per minute creating the equation of : t = 9k

I think 63, but I'm not sure, how do I delete an answer-

Answer:

x=63

Step-by-step explanation:

∠BAC=∠ACD=x(AB∥CD)

∠BCA=∠BAC=x(base∠s, isos△)

∠？BC+∠BCA=90（ext.∠of△）

27+x=90

x=90-27

x=63

♥ To solve this you are going to find x. ♥

♥ X in this case is representing a unknown variable, meaning we are not sure of the number x, and to finish the solution to your problem we have to find x.

♥ So to find x the first step is to simplify both sides of the equation.

♥ Starting with distribution:

$6=(-3)(x)+(-3)(2) \n 6=-3x+-6 \n 6=-3x-6$

♥ Now we want to flip the equation.

$-3x-6=6$

♥ Our next and almost final step, is to add the number -3 to both sides of our problem. This is going to help us tremendously.

$-3x-6+6=6+6 \n -3x=12$

♥ Now our last step before we get our answer is to divide both sides of the problem. In this case we are going to do this:

$(-3x)/(-3) = (12)/(-3)$

♥ And then because of that we get our final answer of: -4.

♥ x=-4 ♥
