1.when you change the first equation to the form it is the same as the second which means infinite solutions

y-3x=5 --->y=3x+5 then set them equal to find many possible solutions

2.this is no solution because the slopes are the same when you combine these equation the 2's cancel out and you ar left with y=12x which cannot be solved

3.when everything is different there is one solution

Kevin is solving this problem. 737 × 205 What are the partial products Kevin will need to solve the problem? A. 3,685 and 147,40

Andrew [12]

the answer is A

700 x 5 = 3500

30 x 5 = 150

7 x 5 = 35

3500 + 150 +35 = 3685

700 x 200 = 140,000

30 x 200 = 6000

7 x 200 = 1400

140000 + 6000 + 1400 = 147400

At which value will the graph of y=tanx have a zero? Please explain the correct answer!

Rina8888 [55]

Answer: None of the above are correct.

Step-by-step explanation:

Given function: $y=\tan x$

We know that the value of tan x =0 at x=0.

Also, $At\ x=\frac{\pi}{3},\ \tan\frac{\pi}{3}=\sqrt{3}$

$At\ x=\frac{\pi}{2},\ \tan\frac{\pi}{2}=\infty$

$At\ x=\frac{\pi}{3},\ \tan\frac{\pi}{4}=1$

Hence, the only option is correct is "None of the above are correct".

The endpoints of the diameter of a circle are (-7, 3) and (5, 1). What is the center of the circle?

MrMuchimi

Answer: C. (-1, 2)

<u>Step-by-step-explanation:</u>

The center is the midpoint of the endpoints

→ $\bigg(\dfrac{x_1+x_2}{2}$ , $\dfrac{y_1+y_2}{2}\bigg)$

→ $\bigg(\dfrac{-7+5}{2}$ , $\dfrac{3+1}{2}\bigg)$

→ $\bigg(\dfrac{-2}{2}$ , $\dfrac{4}{2}\bigg)$

→ (-1 , 2)

The midpoint is (-1, 2)
