Answer:
C = -5
Step-by-step explanation:
Functions
F(x) is defined as:
[tex]\displaystyleF(x)=\frac{C-x}{D-x}[/tex]
We know F(-2) is undefined. It comes from the fact that the denominator is 0 for this value of x, thus:
D - (-2) = 0
Solving:
D = -2
Substituting:
[tex]\displaystyleF(x)=\frac{C-x}{-2-x}[/tex]
We also know F(-1) = 4:
[tex]\displaystyle \frac{C-(-1)}{-2-(-1)}=4[/tex]
[tex]\displaystyle \frac{C+1}{-2+1}=4[/tex]
[tex]\displaystyle \frac{C+1}{-1}=4[/tex]
Multiplying by -1
C + 1 = -4
Solving for C:
C = -5

Answer:
w=28
Step-by-step explanation:
multiply both side by 4:
[tex]4*(\frac{w}{4} -4)=3*4\\4*\frac{w}{4}-16=12\\w-16=12[/tex]now add +16 in both side:
[tex]16+w-16=12+16\\w=28[/tex]
John invested his inheritance of $12000 in 3 different funds part in a money market fund paying 3% interest annually Parton monusco bonds paying 4% annually and the rest in mutual funds paying 7% annually John invested 4000 more in mutual funds than he invested in municipal bonds the total interest in one year with $670
Answer:
John invested $2,000 in money-market fund, $3,000 in municipal bonds, and $7,000 in mutual funds.
Step-by-step explanation:
Note: This question is not complete. The complete question is therefore provided before answering the question as follows:
John invested his inheritance of $12,000 in three different funds: part in a money-market fund paying 3% interest annually; part in municipal bonds paying 4% annually; and the rest in mutual funds paying 7% annually. John invested $4,000 more in mutual funds than he invested in municipal bonds. The total interest earned in one year was $670. How much did he invest in each type of fund?
The explanation of the answer is now given as follows:
Let a, b and c represent the amount invested in money-market fund, municipal bonds and mutual funds respectively. Therefore, the sum of the three principal amounts can be represented as follows:
a + b + c = 12,000 ……………………….. (1)
Since John invested $4,000 more in mutual funds than he invested in municipal bonds, we have:
c = b + 4,000 ……………………………. (2)
The total amount of interest earned from each fund can be represented as follows:
0.03a + 0.04b + 0.07c = 670 ………………. (3)
Substituting equation (2) into equation (1), we have:
a + b + b + 4,000 = 12,000
a + 2b = 12,000 – 4,000
a + 2b = 8,000
a = 8,000 – 2b ……………………….. (4)
Also, substituting equation (2) into equation (3), we have:
0.03a + 0.04b + 0.07(b + 4,000) = 670
0.03a + 0.04b + 0.07b + 280 = 670
0.03a + 0.04b + 0.07b 0 = 670 – 280
0.03a + 0.11b = 390 ,,,,,,,,,,,,,,,,,,,,,, (5)
Substituting equation (4) into equation (5) and solve for b, we have:
0.03(8,000 – 2b) + 0.11b = 390
240 – 0.06b + 0.11b = 390
240 + 0.05b = 390
0.05b = 390 – 240
0.05b = 150
b = 150 / 0.05
b = 3,000
Substituting b = 3,000 into equation (2), we have:
c = 3,000 + 4,000
c = 7,000
Also, substituting b = 3,000 into equation (4), we have:
a = 8,000 – (2 * 3,000)
a = 8,000 – 6,000
a = 2,000
Therefore, John invested $2,000 in money-market fund, $3,000 in municipal bonds, and $7,000 in mutual funds.

Factorise x2 + 4x + 3
Answer:
(x + 1)(x + 3)
Step-by-step explanation:
Given
x² + 4x + 3
Consider the factors of the constant term (+ 3) which sum to give the coefficient of the x- term (+ 4)
The factors are + 1 and + 3, since
1 × 3 = 3 and 1 + 3 = 4, then
x² + 4x + 3 = (x + 1)(x + 3)

Which answer is an equation in point-slope form for the given point and slope?
Point: (1,9); Slope: 5
A) y−1=5(x+9)
B) y−9=5(x−1)
C) y+9=5(x−1)
D) y−9=5(x+1)
Answer:
B [tex](y-9)=5(x-1)[/tex]
Step-by-step explanation:

[tex](y-y_1)=m(x-x_1)[/tex]
Here
[tex]m=5 \ and \ (x_1, y_1)=(1, 9)[/tex]
therefore equation of line having slope 5 and passing through point )1, 9) is given as

Consider the two expressions. Expression 1: -4(9x-2)+3
Expression 2: -36x+k
What value of k will make the two expressions equivalent?
Answer:
11
Step-by-step explanation:
first, distribute the negative four in Expression 1: -36x+8+3
next, set that equal to Expression 2: -36x+11 = -36x+k
finally, add 36x to both sides: 11 = k

X/5 + 6 = 10

20
-20
Answer:
x = 20
Step-by-step explanation:
The way to solve these problems is by isolating x (getting it by itself on one side).
So let's look at the operations needed! First of all, there's currently a +6 hanging out next to x. We don't want that, so we subtract 6 from both sides.
x/5 + 6 = 10
-6 -6
x/5 = 4
We now see that x is being divided by five. To get just x, we can now multiply both sides by five to get rid of that fraction.
x/5 = 4
*5 *5
x = 20
