Answer:

<h2>The right answer is the second graph.</h2>

Step-by-step explanation:

All choices are attached.

Each graph is representing a system of equations which is not linear, because a parabola is not a linear relation.

According to the problem, we have to choose the system which solution is (-1,1). To do so, we just have to observe which graph has an interception point at (-1,1).

You can observe that the second graph has the interception point at (-1,1), that is, both functions has that point in common, because they intercept there.

Therefore, the right answer is the second graph.

blondinia [14]

Answer:

We choose D.

Step-by-step explanation:

The question is which statement is true?

A. 33% of the people surveyed were vegetarian and though saving energy was not important

=> It is wrong because we do not know the total number of people who were surveyed.

B. This statement is wrong, because we also have 26% non - vegetarian though saving energy was not important

C. This statement is wrong, because there are 38% non - vegetarian though saving energy was not important and only 26% non - vegetarian though saving energy was very important

D. True because there are 36% non - vegetarian though saving energy was somewhat important while there are 17% vegetarian think so. Hence, a person who was not a vegetarian was morel likely than a vegetarian to think that saving energy is somewhat important

=> We choose D.

Tan² B = 4
(tan B)² = 4
tan B = ±2

Basic Angle
= tan^-1 2
= 63.4° (1dp)

B = 63.4°, 116.6°, 243.2°, 296.6°

Assuming you're actually supposed to present your answers in 0dp, then all answers apply.

What is the slope intercept form when m = 1/2 & b = 89 ?<br> Helppppppppp

Zina [86]

Answer:

$y = \frac{1}{2}x + 89$

Step-by-step explanation:

slope-intercept form: y = mx + b

y = (x , y)

x = (x , y)

m = slope = 1/2

b = y-intercept = 89

Plug in the corresponding numbers & variables to the corresponding variables:

y = (1/2)x + 89

$y = \frac{1}{2}x + 89$ is your answer.
