Answer 1

Answer:

All real numbers

Step-by-step explanation:

The domain represents the x-coordinates, so you can see on the graph that it goes all the way out to both the left and right directions, meaning it covers all the negative numbers, and all the positive numbers. The question is trying to trick you into thinking about the range, but forget about the y-axis for this one.

Answer 2

Answers

Answer:

60

Step-by-step explanation:

area of triangle ACF is (1/2) (AC) (CF) = 180

area of triangle BCE = (1/2) (BC) (CE)

BC = AC/2

CE=(2/3) CF

so (1/2) (BC) (CE) = (1/2) (AC/2) (2/3)CF = (1/2)(2/3)(180) = 60 sq cm

i need help factoring polynomials and knowing the steps to reach the answer. 1) x² - 7x + 10 as well as 2) 6r² + 19r - 20

Answers

Answer:

1)  (x-2)(x-5)

2) (6r-5)(r+4)

Step-by-step explanation:

1)

It will just be x since the coefficient is 1

To figure out the second number you need to think of the multiples of 10.  

So either 2 and 5 or 1 and 10.  Since 2 and 5 add to 7 it's them.  

They're negative since 7 is and can still make a positive 10.

2)

This one is more just plugging and guessing to see which on works.

Find the multiples of both 6 and 20, afterwards plug in the multiples til you get 19 in the final product.  

Since 20 was negative the one of the numbers would be negative.

Geometry 12 16 2020​

Answers

Answer: A) 2/3

Method: Here’s an easy method for questions like these, when you are looking at a triangle, look at the angle that’s away from the biggest line (if it’s a right triangle choose any angle), for this case angle W. Now count how many lines it takes to get to the big line, for the original triangle it’s 6 and for the new triangle it’s 4. Now since you have your numbers turn it into a fraction (new on top original on bottom), 4/6. Finally see what the answer is, for this case 4/6 is equal to 2/3, so there’s your answer.
