Answer:

1. If x=5, 3*5=15, 15*15=225 + y (3) = 228.

2. If y=4, then 10*4 = 40, 4^2 is 16, so 40 + 16 is 56.

I might be wrong, but the first one you answered, x^2, x= 1/2, I think that is wrong. when something is squared, you don't go, "Oh, well since 1/2 equals 1, that's the answer." The way to figure out something like this is... 1/2 times 1/2, which is .25, or 1/4. Another example: 3^5 . The way to find this out is 3*3*3*3*3 = 243. But  you don't go 3*5, because that answer would be 15, which is not correct.

To pass this year's math class, Miriam needs to earn at least an 82%. Write an inequality that shows the scores Miriam could get
sergey [27]

The inequality that shows the scores Miriam could get to pass her math class is 82\%\leq x \leq 100\%

<em><u>Solution:</u></em>

Given that To pass this year's math class, Miriam needs to earn at least an 82%

To find: Inequality that shows the scores Miriam could get to pass her math class

Let "x" be the Miriam's score in the math class

Given she should score at least 82 %

Therefore, we can frame a inequality as:

x\geq 82 \%

Here we used "greater than or equal to" , because she can score 82 % or more than 82 % also

The maximum score is 100 %

Hence we can frame a inequality as:

x\leq 100 \%

Here, we used "less than or equal to" , because she can score the maximum score of 100 % or less than 100 %

Combining both the inequalities we get,

82\%\leq x \leq 100\%

All real numbers greater than or equal to 82% and less than or equal to 100%

Thus the required inequality is found

Which ordered pairs could be points on a line parallel to the line that contains (3, 4) and (–2, 2)?
Olin [163]
The equation of the line containing the points (3, 4) and (-2, 2) is:
 y-yo = m (x-xo)
 Where,
 m = (y2-y1) / (x2-x1)&#10;&#10; m = (2-4) / (- 2-3)&#10;
 m = (-2)/(-5)&#10;&#10;m = 2/5
 (xo, yo) = (-2, 2)&#10;
 Substituting values:
 y-2 = (2/5) (x - (- 2))&#10;
 y-2 = (2/5) (x + 2)&#10;&#10; y = (2/5) x + 4/5 + 2&#10;&#10; y = (2/5) x + 14/5
 A parallel line is one that has the same slope:
 y = (2/5) x&#10; 
 An ordered pair that passes through this line is (0, 0).
 Answer:
 
A parallel line is:
 y = (2/5) x&#10;
 an ordered pair that goes through the parallel line is:
 
(0, 0)
