Give the equation of a line that goes through the point ( − 24 , 2 ) and is perpendicular to the line 8 x + 3 y = − 6 . Give your answer in slope intercept form

Answers

Answer:

[tex]y=\frac{3}{8}x+11[/tex]

Step-by-step explanation:

To find a line that is perpendicular to 8x + 3y = -6 and goes through (-24, 2), lets first find what the line's slope would be.

We can find this by finding the slope of 8x + 3y = -6 and taking the negative reciprocal of it.

We can find the slope of that line by putting it in slope-intercept form:

8x + 3y = -6

Subtract 8x from both sides.

3y = -6 - 8x

Divide both sides by 3.

[tex]y=-\frac{6}{3}-\frac{8}{3}x[/tex]

[tex]y=-\frac{8}{3}x-2[/tex]

So the slope of that line would be -8/3.

The negative reciprocal of -8/3 would be 3/8.

Now we know that the new line would have to pass through the point (-24, 2). We can use this point and write the equation in point-slope form:

[tex]y-2=\frac{3}{8}(x+24)[/tex]

Now lets change this into slope-intercept form. Add 2 to both sides.

[tex]y=\frac{3}{8}(x+24) +2[/tex]

Distribute the 3/8.

[tex]y=\frac{3}{8}x+9+2[/tex]

Simplify.

[tex]y=\frac{3}{8}x+11[/tex]

And now we have our equation in slope-intercept form.

I hope you find this helpful.

Given f (x) = 3x - 8 find x if f(x) = -14​

Answers

Answer:

[tex]x=-2[/tex]

Step-by-step explanation:

So we have the function:

[tex]f(x)=3x-8[/tex]

And we want to solve for x if f(x) is -14.

So, substitute -14 for f(x):

[tex]-14=3x-8[/tex]

Add 8 to both sides:

[tex]-6=3x[/tex]

Divide both sides by 3:

[tex]x=-2[/tex]

And we're done!

Answer:

The value of x is -2 .

Step-by-step explanation:

You have to solve it by doing comparison :

[tex]f(x) = 3x - 8[/tex]

[tex]f(x) = - 14[/tex]

[tex]3x - 8 = - 14[/tex]

[tex]3x = - 14 + 8[/tex]

[tex]3x = - 6[/tex]

[tex]x = - 6 \div 3[/tex]

[tex]x = - 2[/tex]

Suppose we get 24 inches of snow tomorrow. Warm weather comes the next day. For the next several days it stays warm and begins to melt the snow. If the snow melts at 2.5 inches a day, how much snow will be left on the ground after 7 days?

Answers

Answer:

6.5 inches

Step-by-step explanation:

Suppose we get 24 inches of snow tomorrow

The next day becomes warm.

The weather remains warm for the next several days.

The snow melts at 2.5 inches a day

Therefore the amount of snow that will be left after 7 days can be calculated as follows

= 2.5 ×7

= 17.5

Since the initial amount of snow was 24 inches then,

24 -17.5

= 6.5

Hence the amount of snow that will be left on the ground after 7 days is 6.5 inches

Chen is baking muffins and banana bread for a brunch buffet. He needs 3 and one-fifth cups of flour to make the muffins and 3 and two-thirds cups of flour to make the banana bread. Which is the best estimate of the number of cups of flour that Chen needs to bake both recipes? 6 cups of flour 7 cups of flour 8 cups of flour 9 cups of flour

Answers

answer:

7 cups of flour

reason:

to find how much flour is needed, first you need to combine the two fractions.
to add the fractions, you first have to find a common denominator, which in this case is 15
multiply 1/5 by 3 to get 3/15, and 2/3 by 5 to get 10/15. combined, this is 13/15
since the answer is looking for the best estimate, you take the overall amount of flour, which would be 6 13/15, which is closer to 7 cups than 6

(I may be wrong this is just how I did it)

Answer:

The answer would be b. 7 cups of flour.

Evaluate the function f(x)=3x+12 with x+6.

f(x+6) = 6x + 60

f(x+6) = 2x - 30

f(x+6) = 3x + 30

f(x+6) = 30

Answers

Answer:

f(x+6)= 3x + 30

Step-by-step explanation:

Whenever you have to evaluate a function with a certain value, replace the variable x with a certain value. In this case, substitute x with the value of (x+6). You get the equation f(x+6)= 3(x+6) + 12, which simplifies into f(x+6)= 3x + 18 +12, which further simplifies into f(x+6)= 3x + 30.

Problem 2

Plot point L anywhere that isn't on segment JK. Draw a line through point L. I find it helps to make the lines parallel.

Next, use a compass to measure the width of segment JK. Keeping this same width, transfer the nonpencil end of the compass to point L. Draw an arc that crosses the line through L.

Mark this intersection point M. Lastly, use a pen or marker to form segment LM and erase everything else of that line.

======================================================

Problem 3

The ideas of the previous problem will be used here. We copied segment JK to form congruent segment LM. So JK = LM.

The same steps will be used to form segment GN where GN = EF. In other words, segment GN is a perfect copy of segment EF.

If you repeat these steps again, you'll get another segment of the same length. This segment goes from point N to point H. So NH = GN = EF

Then we can say,

GH = GN + NH

GH = EF + EF

GH = 2*EF

It’s bath time while filling the tub dad used the last capful of bubble bath.after doing quick search for more to buy he notices that he can get 36oz for $3.79 or 24 oz for $2.89. Which of these options is the better deal ?

Answers

If you divide the price by the number of ounces, you will get how much you are paying for a single ounce.

[tex]\frac{3.79}{36}[/tex] ≈ 0.11 dollars per ounce

[tex]\frac{2.89}{24}[/tex] ≈ 0.12 dollars per ounce

As you can see, you are paying about 0.01 dollars more for every ounce of bubble bath in the second option. So you are better off buying 36 ounces for 3.79 dollars.

You can also do this buy dividing ounces by dollars.

[tex]\frac{36}{3.79}[/tex] ≈ 9.5 ounces per dollar

[tex]\frac{24}{2.89}[/tex] ≈ 8.3 ounces per dollar

Again, you can see that you get about 1 more ounce for every dollar you pay in the first option. So 36 ounces for 3.79 dollars is the way to go.

Answers

Step-by-step explanation:

How to check a solution: Just as you can check the solution to an equation, you can check a solution to an inequality. First, you check the end point by substituting it in the related equation. Then you check to see if the inequality is correct by substituting any other solution to see if it is one of the solutions.

How to tell if its true or false: An inequality is a statement that shows the relationship between two (or more) expressions with one of the following five signs: <, ≤, >, ≥, ≠. Like an equation, an inequality can be true or false. 34 - 12 > 5 + 2 is a true statement. 1 + 3 < 6 - 2 is a false statement.
