Answer:

The root of this equation would be A) x=1

Step-by-step explanation:

To get this, you first need to bring the 98x over to the left side.

49x^2-98x+49=0

Then, you can simplify the equation by taking out 49.

49(x^2-2x+1)=0

Then, factor that equation to get 49(x-1)(x-1)=0 or 49(x-1)^2=0

Thus, your root would be x=1

Sorry this is a little late, but I hope this helped you!

HELP PLEASE !?!? I suck at math
Anna35 [415]
To graph the equation, plot a few points then connect then with a line.

f(x) = 440 - 55x

Plug in numbers for x to get the y value.

f(0) = 440
f(1) = 385
f(2) = 330
f(3) = 275
f(4) = 220
f(5) = 165

So when you graph these points, the y intercept is y = 440 because the graph crosses the y axis at (0, 440).

The x intercept is where the graph crosses the x axis. This happens when y = 0.

0 = 440 - 55x. Solve for x.

55x = 440
x = 8

So the x intercept is x = 8

Talia uses 10 strawberries and 4 oranges to make 8 servings of fruit salad. How many oranges and strawberries does Taila needs t
yarga [219]
Since 12 is 8 x 1 1/2 she needs 1 1/2 time as much fruit.


1 1/2 x 10 = 15 strawberries  and 1 1/2 x 4 = 6 oranges.

You could also solve this using proportions:

\frac{10}{8} =  \frac{n}{12}

Cross multiply and get 8n= 120  divide by 8 and get 15 strawberries

Do the same for the oranges:

\frac{4}{8} =  \frac{n}{12}

You can see that 4/8 = 1/2 so n/12 has to be 6 to be 1/2 (or solve it using cross products like I did above).

A biker cycles 9 miles in 2 3 of an hour.
Aloiza [94]

Answer:

2 hours: 27 miles, 3 hours: 40.5 miles, 3.5 hours: 47.25 miles

Step-by-step explanation:

1.) If a hiker hikes 9 miles in 2/3 of an hour, he will hike 4.5 (Half of 2/3 is 1/3 and half of 9 is 4.5) miles in 1/3 of an hour and 13.5 miles per hour. (1/3 times 3 gives us a whole and 4.5 times 3 is 13.5)

2.) 2 hours: 13.5 * 2 = 27 miles

3.) 3 hours: 13.5 * 3 = 40.5 miles

4.) 3.5 hours: 13.5 * 3.5 = 47.25 miles
