The y intercept is (0,-7). some other points would include (1,-5), (2,-2), (3,1), etc

Answer:

Answer (e)

Step-by-step explanation:

Note that this graph has a zero at x = 1 and a vertical asymptote at x = -4. Only Answer (e) corresponds to that. Try letting x = 1. y is zero, correct? Try letting x = -4. y is undefined, correct?

The graph shows the system y=2x+1 y=2x^2+1 Which ordered pairs are solutions of the system?

zhenek [66]

Hey!

To solve this problem, we would really have to graph both equations.

OPEN THE FIRST IMAGE

The first image I provided was the image of this equation graphed: y=2x+1

OPEN THE SECOND IMAGE

The second image I provided was the image of this equation graphed: y=2x^2+1

PLEASE DO NOT LOOK AT THE THIRD IMAGE YET!

The first image has two points. One at ( -0.5, 0 ) and the other at ( 0, 1 ).

The second image has only one point, which is at ( 0, 1 ).

OPEN THE THIRD IMAGE

Now, when both are combined we see that they intersect at two points, which are ( 0, 1 ) and ( 1, 3 ).

So, our answer is...

The ordered pairs that are the solution to the system are ( 0,1 ) and ( 1,3 ).

Hope this helped!

A chef is going to use a mixture of two brands of Italian dressing. The first brand contains 8% vinegar, and the second brand co

Flura [38]

Let f and s denote the amounts of the first and second brands that the chef is going to use.

She wants to end up with 290 mL, so

f + s = 290

Each mL of the first brand contains 0.08 mL of vinegar, and each mL of the second contains 0.13 mL of vinegar. The final mixture should have a concentration of 12% vinegar, so that it contains 0.12 • 290 mL = 34.8 mL of vinegar, and

0.08f + 0.13s = 34.8

Solve for f and s :

f + s = 290 → s = 290 - f

0.08f + 0.13 (290 - f ) = 34.8

0.08f + 37.7 - 0.13f = 34.8

0.05f = 2.9

f = 58

s = 290 - 58

s = 232
