What is the slope of the line that passes through the points (-2, 7) and (2,-5)?

Mathematics
1 answer:
Deffense [45]3 years ago
4 0

Answer:

Denote that line: y = ax + b

Line passes (-2, 7) and (2,-5):

=> -2a + b =7

=>  2a + b = -5

Add both side of above equations:

=> 2b = 2

=> b = 1

=> a = (-5 - 1)/2 = -3

=> Slope a = -3

Hope this helps!

The volume of a cylindrical container
Ray Of Light [21]

Answer:

A. \frac{3}{4}\textrm{ gal}

Step-by-step explanation:

Given:

Volume of the cylindrical container before dilation, V_{i}=1\textrm{ gal}

Scale factor of the dilation, SF=\frac{3}{4}

Therefore, the volume of the dilated cylinder is given as:

V_{f}=SF\times V_{i}

Plug in 1 gal for V_{i} and \frac{3}{4} for SF. Solve for V_{f}. This gives,

V_{f}=\frac{3}{4}\times 1\\V_{f}=\frac{3}{4}\textrm{ gal}

Therefore, the volume of the dilated cylinder is \frac{3}{4} gallons.

Please help me with this question!
mixer [17]

Hi! I'm happy to help!

To solve this, we have to divide the 18 pounds, in 1/8 portions. We do this with division. To make this problem easier to solve, we need to turn it into a multiplication problem (opposite of division). To still make the problem correct, we have to take the opposite of one of our numbers. Let's take 1/8, and turn it into 8, now we have the problem:

18×8=

Now all we have to do is multiply:

18×8=

144

He can make 144 croissants!

I hope this was helpful, keep learning! :D
