C = (a - 4b - 11) / -4
Answer:
c = -a/4 + b + 11/4
Step-by-step explanation:
Solve for c:
a = -4 c + 4 b + 11
a = -4 c + 4 b + 11 is equivalent to -4 c + 4 b + 11 = a:
-4 c + 4 b + 11 = a
Subtract 4 b + 11 from both sides:
-4 c = a + (-4 b - 11)
Divide both sides by -4:
Answer: c = -a/4 + b + 11/4

There are only one or two variables in a linear equation. No variable can be multiplied by a number larger than one or used as the denominator of a fraction in a linear equation.

3x+4 < 4 pls some one help me pls it’s my last problem for my homework
Answers
Answer:
x < 0
Step-by-step explanation:
We are given this inequality:
3x + 4 < 4
And we want to solve it.
Solving inequalities is very similar to solving equations. We want to isolate the variable (in this case, x) on one side, while leaving the numbers on the other side.
To start, we can subtract 4 from both sides.
3x + 4 < 4
-4 -4
__________________
3x < 0
Now, we have the numbers on one side and the variable on the other, but we aren't done yet, as we want to solve for the value of x, or 1x, not the value of 3x.
So, we'll need to divide both sides by 3.

a godown had a stock of cloth of Rs.160000. Due to a fire a part of the merchandise, wroth Rs. 20000, was completely destroyed. find the loss percent?
Answers
The loss percentage of cloth is 12.5%.
Stock of cloth = Rs. 1,60,000
worth of destroyed cloth = Rs. 20,000
A percentage is a number or ratio that can be expressed as a fraction of 100. It is denoted by the symbol %.
Percentage = Value/ Total value × 100%
Loss percentage = Loss/Total value × 100%
So, the loss percentage of cloth = 20,000/1,60,000 ×100%
= 0.125 × 100%
= 12.5%.

Jaquan passed a checkpoint jogging at a constant speed of 9 km/h. Then, 2 minutes later Odalis passed the same checkpoint.
If Odalis runs at a constant speed of 12 km/h, then how far past the checkpoint will Odalis be when they catch up to Jaquan?
Answers
The distance from the check point when Odalis catch up Jaquan is 1.2 kilometers.
What is relative speed ?Relative speed is the net speed difference when objects move in the same direction and sum of individual speeds when objects move in opposite direction.
Given Jaquan speed is 9km/hr which is 0.15km/minute and Odalis has a speed of 12km/hr which is 0.2km/minute.
∴ The relative speed difference between Jaquan and Odalis is
= (0.2 - 0.15) km/hr.
= 0.05 km/hr.
Given Odalis reached the check post after 2 minutes in this time Jaquan have covered (2×0.15) kilometers.
= 0.30 kilometers.
Now to catch up Jaquan, Odalis will need (0.30/0.05) minutes which is
= 6 minutes.
∴ The distance from the check post Odalis travelled to catch up with Jaquan is (0.2×6) kilometers.
= 1.2 kilometers.

26 ounces for $3.33 40 ounces for $
Answers
The least cost per unit of peanut butter is $0.095 for 20 ounces for $1.90 therefore option (B) will be correct.
What is the arithmetic operator?Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,
Division = divide any two numbers or variable called division.
Given the four options of jars;
1) 16 ounces for $1.70
Cost per ounces = 1.70/16 = $0.10625
2) 20 ounces for $1.90
Cost per ounces = 1.90/20 = $0.095
3) 26 ounces for $3.33
Cost per ounce = 3.33/26 = $0.128
The least cost per ounce is $0.095 for 20 ounces for $1.90.

Jenna paid a total interest of $4810 (13% of the cost of the car) for the car.
What is APR?Suppose there is initial amount as P.
The interest, or say charge on it is applied annually as 'C' amount.
Taking how much percent of P is C, we get:
[tex]APR = \dfrac{C}{P} \times 100[/tex]
WE have been given that Jenna bought a new car for $37,000 and paid a 10% down payment and financed the remaining balance for 72 months with an APR of 6.5%
Assuming that she makes monthly payments, to determine the total interest Jenna pays over the life of the loan.
The cost = $37,000
Time = 72 months
APR = 6.5%
Then;
Interest = (37,000 x 6.5 x 2) /100
= $4810
Percentage of interest paid = (4810/37,000 ) x 100
= 13%
Therefore, Jenna paid a total interest of $4810 (13% of the cost of the car) for the car.

write an equation in slope- intercept form for the line described.
perpendicular to y = 1/4x + 2 passes through (0,0)
Answers
Answer:
y=-4x+0
Step-by-step explanation:
Slope form is y=mx+b
m is the slope, and b is the y intercept. If the line must pass through (0,0) then the y intercept would be zero.
This give you y=mx+0
Now to find the slope you need a perpendicular line to the previous line. This would mean you have to swap 1/4 which is the previous lines slope.
1/4 is a positive so make it a negative, -1/4
Now flip -1/4 to make is -4/1 which also equals -4
Now with the slope -4 and y-intercept 0, you know you equation

The approximate rate of change of the function is 224.95
Rate of change of functionThe rate of change of the given function is expressed according to the equation below;
f'(x) = f(b)- f(a)/b-a
Given the interval [-4, 3]
a = -4
b = 3
f(a) = 9(-4)⁴ + 7/(-4)²
f(-4) = 2304+ 7/16
f(-4) = 2304.4375
f(b) = 9(3)⁴ + 7/(3)²
f(3) = 729 + 7/9
f(3) = 729.7778
Substitute to have:
f'(x) = 729.7778-2304.4375/3+4
f'(x) = 1574.65/7
