Try them step by step

2/3=3/2? No

3/5=12/20? Lets try and see

If we <span>simplify 12/20 what do we do? Well we take 4*3=12 and 4*5=20

Now that we simply the 4 from both the numerator and denominator we get our answer 3/5

Your answer will be B.</span>

Which function has the largest amplitude?

frutty [35]

<h3>Answer: Choice A</h3>

The -3 out front of that function means |-3| = 3 is the amplitude, which is the largest of the four functions.

In general, the sine function is

y = A*sin(B(x-C)) + D

where |A| is the amplitude. In the first answer choice, A = -3 so |A| = |-3| = 3.

Cosine has the same format since cosine is just a phase shift of sine.

A line passes through the point (–2, 7) and has a slope of –5.

ICE Princess25 [194]

Answer:

B

Step-by-step explanation:

Let's create an equation in point-slope form, which is: $y-y_1=m(x-x_1)$ , where $(x_1,y_1)$ is the point and m is the slope.

Here, our point is (-2, 7) and our slope is m = -5 so plug these in:

$y -7=-5*(x-(-2))$

$y -7=-5*(x+2)$

Now, if (a, 2) lies on this line, then it should satisfy the equation. So plug in a for x and 2 for y:

2 - 7 = -5(a + 2)

-5 = -5(a + 2)

Divide by -5:

1 = a + 2

Subtract 2 from both sides:

a = -1

Thus, the answer is B.

Hope this helps!

How do I find range and domain in algebra (graph)

Ierofanga [76]

Answer:

You can find the range by seeing the y-value of the plotted points.

You can find domain by looking at the x-values of the plotted points.

Hope you found this helpful!!!
