Answer:
The following expressions become negative:
- 3) x times y = xy = (1)(-2) = -2
- 4) x divided by y = x/y = 1/-2 = -2
Step-by-step explanation:
Given
Computing by substituting x = 1, and y = -2
1) x+y = 1+(-2) = -1
2) x - y = 1 - (-2) = 1+2 = 3
3) x times y = xy = (1)(-2) = -2
4) x divided by y = x/y = 1/-2 = -2
It is clear from the above calculations that when we put x = 1, and y=-2 then the expressions (x+y), (x times y), and (x divided by y) become negative.
Therefore, the following expressions become negative:
- 3) x times y = xy = (1)(-2) = -2
- 4) x divided by y = x/y = 1/-2 = -2
Half of 36 is greater than one seventh of 14
Answer:
E. -8/3
F. 8/3
Step-by-step explanation:
9x^2-64=0
Add 64 to each side
9x^2-64+64 = 0+64
9x^2 =64
Divide each side by 9
9x^2/9 = 64/9
x^2 = 64/9
Take the square root of each side
sqrt(x^2) = ±sqrt(64/9)
We know that sqrt(a/b) = sqrt(a)/sqrt(b)
x = ±sqrt(64)/sqrt(9)
x = ± 8/3
Since 3 is greater than -3, hence (-1, 3) lie in the solution set. Option C is correct
In order to determine the points that lie in the solution set of the inequality y > 3x +10, we will substitute the x-coordinate and see if <u>y is greater than the result.</u>
<u />
For the coordinate point (1, 10)
y > 3(1) +10
y > 13
Since 10 is not greater than 13, hence (1,10) does not lie in the solution set.
For the coordinate point (4, 20)
y > 3(4) +10
y > 22
Since 20 is not greater than 22, hence (4,20) does not lie in the solution set.
For the coordinate point (-1, 3)
y > 3(-1) +10
y > -7
Since 3 is greater than -3, hence (-1, 3) lie in the solution set.
