Answer:
x = ± 2
Step-by-step explanation:
Given
x² = 4 ( take the square root of both sides )
x = ± 
= ± 2
Since 2 × 2 = 4 and - 2 × - 2 = 4
Step-by-step explanation:
For SAS, you need two sides to be in proportion and the included angles to be congruent.
A) included angle between XY and YZ is Y, so wrong
B) included angle between UV and WV is V, so correct.
C) this ratio is just wrong.
D) included angle between XZ and ZY is Z, and the ratios check out, so correct.
Answer:
1 is correct, 100.
2 is 500, not 470. since we're rounding to the nearest hundred, we would look at the tens place and if it's higher than 5 then round up.
3 is correct.
4 is correct.
5 is correct.
6 is correct.
7 is correct.
8 is 290, not 300. like i said before, but in this case we're rounding t the nearest ten instead of hundred. but the same rules apply.
9 is correct.
and 10 is correct!
i think that you did pretty well on most of these, but remember the rounding rule.
-13.19 is going to be the answer
Given:
Let t = number of hours worked
Let p = money in the paycheck
And the relationship between the two variables varies DIRECTLY, thus they are equated with one another.
Well anyway, you can write this simple equation for their relationship:
16t=124p
Then you derive if you want to get the number of hours or the amount paid:
1) 16t/16= 124p
t = 124p/16
t=7.75p
or
2) 124p=16t
124p/124= 16t/124
p = 0.129t
