Do 4x^2 = 16x

16x+6 = 40

     -6    -6

16x = 34

/16    /16

x=2.125

Rounded to the nearest hundredth is, 2.13

Question 3
Fiesta28 [93]
Answer: y = -6x + 2

m = y_2 - y_1
/ x_2 - x_1

-10 - 8
/ 2 - (-1)

= -18/3 = -6

m (slope) = -6

y = mx + b
y = -6x +b

Find b using (-1,8)
y = -6x +b
8 = -6(-1) + b
8 = 6 + b
-6 -6
2 = b

Final answer: y = -6x + 2

To check using one of the points: (-1,8) or (2,-10)
y = -6x + 2
-10 = -6(2) + 2
-10 = -12 + 2
-10 = -10
This is a true statement.

kathy uses a 1/2 cup of milk with every bowl of her favorite cereal if there are only 3 3/5 cups of milk left, then how many bow
Murrr4er [49]

Taking a quotient, we will see that she can make 7 bowls of cereal (and some leftover milk).

<h3>How many bowls of cereal would kathy have?</h3>

We know that for each bowl, she needs 1/2 cups of milk.

And we also know that she has a total of (3 + 3/5) cups of milk.

To know how many bowls she can make, we need to take the quotient between the total that she has and the amount that she needs for each bowl:

(3 + 3/5)/(1/2)

We can rewrite the total as:

3 + 3/5 = 15/5 + 3/5 = 18/5

Then the quotient becomes:

(18/5)/(1/2) = (18/5)*2 = 36/5 = 35/5 + 1/5 = 7 + 1/5

So she can make 7 bowls of cereal (and some leftover milk).

Tyrel evaluated the expression 2 1/2−3/4. Which is one way he can check his work?
Oxana [17]

Answer:

1 3/4 = 7/4 = 1.75

Step-by-step explanation:

The process to arrive to the solution is explained in the pictures below.

Tyler needed to convert the mixed fraction

2 1/2  = (4+1)/2 = 5/2

If we multiply by 2 numerator and denominator

5*2/2*2 = 10/4

We substract

10/4 - 3/4 = 7/4 = 1.75
