{-4x + 4y = -8 { x - 4y = -7

Mathematics

o-na [289]3 years ago
4 0
I assume you're doing elimination, so

The + 4y and - 4y would cancel out, giving you:

-4x = -8

x = -7

Then, you subtract the x values and add the -8 and -7

-3x = -15

Your answer will be

*x = 5

Someone PLEASE HELP ME!

<span>The graph will get flatter from –1 to 1.As you raise a proper fraction to higher even powers, you get smaller values, so the y-values get closer to the x-axis.The graph will get closer to the y-axis, or narrower.As you raise values greater than 1 (or less than –1) to higher even powers, you get larger values, so the graph increases at a faster rate.

I hope my answer has come to your help. God bless and have a nice day ahead!

Mr. Ignacio went diving along the coral reef in Oahu. He descended 12 meters below the sea. The difference between this point on
Aliun [14]

Answer:

488 meters above sea level.

Step-by-step explanation:

Since the difference between that point and the tallest point is 1,232 you need to subtract 1,232 - 12 = 1,220 to get how far Mt ka'ala is from sea level. Since the ranger station is 2/5 up the mountain you can do 1,220/5 = 244. This is 1/5 of the way up the mountain. Then you do 244 x 2 = 488. That is 2/5 up the mountain. Final answer: The ranger station is 488 meters above sea level.

BaLLatris [955]

Answer:

Step-by-step explanation:

Given that a study was conducted to find out if a new exercise program was more effective than an old one at improving cardiovascular fitness.

Subjects were randomly selected to participate and then randomly assigned to one of the two programs. After six months of exercising, they were given a score based on their fitness performance. Scores ranged from 19 to 73, with higher scores indicating higher performance.

Here there are two groups one for each program.  After recording the scores groupwise, mean, std deviation of each group to be calculated.

Then independent sample test (option B) to be done.

Paired data set is not right because same person cannot be in two programs.

Here proportion is not recorded so D is wrong.  Since variance is not checked anova is not right.  Independence is not checked so E is wrong.  Regression is wrong because there is no estimate for regression line here

B) is right.
