X2 - 10x = 7

You move the constant to the right which looks like: - 10x = 7 - 2

- 10x = 5

Then you divide both side by -10. The answer is:

X = -1/2 OR x = -0.5

We can use trigonometry.  The cosine of 15 will be the side adjacent to the 15-degree side (the one we are looking for) divided by 20, the hypotenuse.  As cos(15) is about .966, we get 19.32 as the side we are looking for.

A fruit stand has to decide what to charge for their produce. They need \$10$10 for 44 apples and 44 oranges. They also need \$1
KatRina [158]

Answer:

<em>We can't find a unique price for an apple and an orange.</em>

Step-by-step explanation:

Suppose, the price of an apple is x and the price of an orange is y

They need $10 for 4 apples and 4 oranges. So, the first equation will be.......

4x+4y=10 ........................................(1)

They also need $15 for 6 apples and 6 oranges. So, the second equation will be........

6x+6y= 15 ........................................(2)

Dividing equation (1) by 2 on both sides :  2x+2y= 5

Dividing equation (2) by 3 on both sides :  2x+2y=5

So, we can see that both equation (1) and (2) are actually same. That means, we will not get any unique solution for x and y here. Both x and y have <u>"infinitely many solutions"</u>.

Thus, we can't find a unique price for an apple and an orange.

Suppose y varies directly with x, and y=-4 when x=8. Find the y when x=14
finlep [7]

14/8 = 1.75

-4 * 1.75 = -7

8 * 1.75 = 14

When x=14, y=-7
