Answer:
16 > 11
Step-by-step explanation:
7 + (16 - 7) = 3 + 8
7 + 9 = 3 + 8
16 = 3 + 8
16 ≠ 11
or
16 > 11
Interval notation(-infinitive, -4)
First divide both sides by 2:
Move the constant term to the right side:
Since
we want to have
Then
So in our equation, we need to add 49/16 to both sides in order to complete the square:
Answer:
6x+8y = 3
Step-by-step explanation:
we have 3x + 4y = 7
4y = -3x + 7
y = -3/4 x + 7/4
so slope is -3/4
2 parallel lines always have same slope
so the slope of our new line is -3/4
so y = -3/4 x + C
for c,
we have (x,y) = (-2/3,7/8)
7/8 = -3/4 * -2/3 + C
C = 3/8
so equation is
y = -3/4 x + 3/8
simplyfyig,
8y = -6x + 3
or, 6x+8y = 3
Answer:
$10000
Step-by-step explanation:
Given that:
Molly invested $50,000 in various stocks and bonds.
She earned 15% on bonds and 18% on stocks
Let the bonds be denoted by a
However, her profit on both types of investment is said to be $8700
We are to find how much of the $50,000 did she invest in bonds.
i.e
0.15a + 0.18(50000-a) = 8700
open brackets
0.15a + 9000 - 0.18a = 8700
Collect like terms
0.15a - 0.18a = 8700 - 9000
-0.03a = -300
Divide both sides by(-0.03); we get
a = 10000
Thus, Molly invested $10000 in the bonds.
