A sports company conducted a road test of a new model of a geared bike. The test rider cycled (3x - 2) miles on a flat road, (x2

- 5) miles uphill, and (2x + 7) miles downhill. Which simplified expression is equivalent to the total distance, in miles, for which the bike was tested?

From the way the question is worded, I think there's a list of choices
that's supposed to go along with it, and I'm sad and disappointed that
you decided not to share them.  But heck, ANYbody can pick the right
answer from a list of choices, but it takes a real Brainly to pick the right
answer from a list of no suggestions at all.

           (3x - 2) + (x² - 5) + (2x + 7) =

             3x - 2 + x² - 5 + 2x + 7  =

          (x²) + (3x + 2x) + (-2 - 5 + 7) =

                    <em>x² + 5x  </em>miles

            or   <em>x (x + 5)</em>  miles  (same thing)

Find the slope of 7x+9y=45
Svetach [21]

Answer: -7/9

Step-by-step explanation: To identify the slope of this line, first notice that this equation is in standard form which is Ax + By = C.

To find the slope, we need to solve for our variable <em>y</em>.

We first need to identify what is happening to our variable <em>y</em>. You can notice that it's being multiplied by 9 and is being added by 7x because 7x is a +7x so we're adding the 7x to the 9y.

So the first thing we do is undo addition and subtraction to our variable.

On the left the -7x's cancel and we are left with 9y. on the right, we do not want to write 45 - 7x because we always want to keep our variable in front of our constant. So I will just write that as 9y = -7x + 45.

Now we can divide everything by 9 in order to get <em>y</em> by itself.

This leaves us with <em>y = -7/9x + 5</em>.

Now our slope is the multiplier or the coefficient of the <em>x</em> term which in this case is -7/9. So the slope is -7/9.

PLEASE HELP AS SOON AS POSSIBLE!!!!WILL GIVE BRAINLY TO CORRECT ANSWER!!!!
Mice21 [21]

Answer:

The correct option which best describes this method is:

Find half of 24 to calculate the radius. Then square the radius and multiply the result by \pi

Option D is correct option.

Step-by-step explanation:

The circumference of table top = 24 \pi inches

We need to find area of table top

The formula used to find area is: Area = \pi r^2

We need to find radius of tabletop.

The formula used to find circumference is: Circumference = 2\pi r

Putting value of circumference we can find radius

Circumference = 2\pi r\\24\pi =2\pi r\\r=\frac{24\pi}{2\pi}\\r=12

So, radius of table top = 12

Now, finding the area:

Area = \pi r^2\\Area=\pi(12)^2\\Area=3.14(144)\\Area=452.16\:inches^2

So, the correct option which best describes this method is:

Find half of 24 to calculate the radius. Then square the radius and multiply the result by \pi

Option D is correct option.

(b) How much the selling price should be fixed for pulse bought for Rs.70 per kg. to earn a profit of Rs.6 after allowing a 5 %
Mama L [17]

Answer:

Rs. 80

Step-by-step explanation:

Given that :

Purchase price = 70

Profit = 6

Discount = 5%

Let selling price = x

Selling price * (1 - discount) = (purchase price + profit)

x * (1 - 5%) = (70 + 6)

x * (1 - 0.05) = 76

x * 0.95 = 76

0.95x = 76

x = 76 / 0.95

x = 80

Hence, selling price = Rs. 80

The slope, M, of the line through the distinct points (x, y) and (y2,y1) is given by the formula m =
rjkz [21]

Answer:

Slope Formula: \displaystyle m=\frac{y_2-y_1}{x_2-x_1}

Step-by-step explanation:

It is wise to remember this formula. It is one of the most important formulas in Algebra and is fundamental in higher level math courses.

We use this formula to determine the slope, or the average rate of change between 2 points.
