Answer: Scale factor = 2

=====================================================

Explanation:

Pick on any pair of corresponding sides. I'll pick the right-most sides of each figure. For figure A, that would be the side of 40 units. Figure B has this corresponding side be 80 units long.

The scale factor is 80/40 = 2. This shows that figure B has sides 2 times longer compared to the corresponding sides on figure A.

So in short all you do is divide the corresponding side lengths. We divide in the format (figureB)/(figureA) because of the transition from A to B, and not the other way around.

What is the slope of the line that passes through the points (1, 1) and (4, 4)?

gizmo_the_mogwai [7]

Answer:

The answer is 1

Step-by-step explanation:

Formula for finding the slope: $\frac{y2-y1}{x2-x1}$

Take y2 and y1 from (4,4) (1,1)

Take x2 and x1 from (4,4) (1,1)

$\frac{y2-y1}{x2-x1} = \frac{4-1}{4-1} = \frac{3}{3} = 1$

This is how the answer is 1

Hope it helps :)

24 = 6 * 4
and
6 + 4 = 10

so its the last choice.

12+root of 35 divided by 2 + 12-2 root of 35 divided by 2

nadya68 [22]

So : $12+ \frac{\sqrt{35}}{2} + \frac{12-2 \sqrt{35} }{2}$ ?

First, you want to bring everything together on the top of the fraction.
12=24/2 so you can have $\frac{24+ \sqrt{35}+12-2 \sqrt{35} }{2}$

Add like terms -- 12 +24 = 36 $\sqrt{35}-2 \sqrt{35} = \sqrt{35}$

Now we are at $\frac{24+ \sqrt{35} }{2}$ Which is the lowest possible simplified version while remaining at exact value.

Feel free to check my math! I kinda did this off the top of my head.

Step-by-step explanation:

Giving out answers for a free test is something wrong but something I can help is to go review or I can help you review because algebra 1 is one easy of a topic when you really hook yourself to it.
