Answer:

y = 3x + 3

Step-by-step explanation:

First, you check for the y-intercept, which is 3 for this equation.

In order to find the slope, pick two points and apply the slope formula.

I would just use rise/run. The slope should be 3/1.

Osvoldo has a goal of getting at least 30%, percent of his grams of carbohydrates each day from whole grains.

Pachacha [2.7K]

To answer this you need to figure out what 30% of the total number of carbs need to be whole-grain. Multiply 0.3 times 220 to get 66 grams. He did not meet his goal. Because he only ate 5 g, this is 61 less than he needs to meet his goal.

<h3>Answer: Choice C</h3>

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

Explanation:

The x coordinate of the preimage point Q is x = 6.

The x coordinate of the image point Q' is x = 21.

The ratio of image over preimage is 21/6 = (3*7)/(3*2) = 7/2

You'll get this same value if you do the same steps with the y coordinates.

Therefore, the scale factor is 7/2 and the dilation rule is $(x,y) \to \left(\frac{7}{2}x, \frac{7}{2}y\right)$

Note: 7/2 = 3.5
