Answer:
x<y-3/13
Step-by-step explanation:
Switch sides'
13x+3<y
Subtract 3 from both sides
13x+3-3<y-3
Simplify
13x<y-3
Divide both sides by 13
13x/13<y/13-3/13
Simplify
x<y-3/13

If two adjacent sides of a rhombus measures 4x – 5 and 7x – 14 respectively. Find the length of each sides.
Answer:
3
Step-by-step explanation:
all sides are equal in a rhombus.
therefore,
[tex]4x - 5 = 7x - 14[/tex]
[tex]14 - 5 = 7x - 4x[/tex]
[tex]9 = 3x[/tex]
[tex]x = 3[/tex]
The total cost c(x) of hiring a dump truck and an operator is described by the function c(x)=300+31x-3.90x^2 , where x is the number of hours worked. Find the number of working hours if c(x)=$220.
Answer:
2.05hrs
Step-by-step explanation:
Given he total cost c(x) of hiring a dump truck and an operator is described by the function c(x)=300+31x-3.90x^2 , where x is the number of hours worked. If c(x)=$220, then;
220 = 300+31x-3.90x^2
300+31x-3.90x^2 - 220 = 0
3.90x^2 + 31x - 80 = 0
x = -31±√31²-4(-80)(3.9)/2(3.9)
x = -31±√961+1.248/7.8
x = -31±47/7.8
x = -31+47/7.8
x = 16/7.8
x = 2.05
hence the number of working hours is 2.05hrs

The mean of 5 numbers is 11. the numbers are in the ratio 1:2:3:4:5 find the smallest number?
The smallest number is x = 11/3. The smallest number in the given ratio of 1:2:3:4:5 whose mean is 11 is 11/3.
Given that the mean of 5 numbers is 11. The numbers are in the ratio 1:2:3:4:5. We need to find the smallest number. We can start solving the problem by following these steps:
Step 1: Let us assume the smallest number to be x.
Step 2: According to the question, the numbers are in the ratio 1:2:3:4:5. Hence, the other four numbers can be written as 2x, 3x, 4x, and 5x.
Step 3: The mean of these 5 numbers is given as 11.
Therefore, we can write:(x + 2x + 3x + 4x + 5x)/5 = 11.
Step 4: Simplifying the above equation, we get:15x/5 = 11x = 11/3.
Step 5: Therefore, the smallest number is x = 11/3.
The smallest number in the given ratio of 1:2:3:4:5 whose mean is 11 is 11/3.

David uses 1/4 cup of apple juice for every 1/2 cup of carrot juice to make a fruit drink . Enter the number of cups of apple juice David uses for 1 cup of carrot juice. HELP ME PLSSS!!!!
Answer:
1/2 cup
Step-by-step explanation:
1 cup is equal to 2 1/2 so that means you use 2 times 1/4 which is 2/4 cups which is equal to 1/2
Answer:
1/2 cup of apple juice
Step-by-step explanation:
Hi,
1/4 cup of apple juice = 1/2 cup of carrot juice
We're trying to find the number of cups of apple juice when the carrot juice is equal to a whole cup. To do this, we have to get 1/2 to a whole number. Simply multiply 1/2 by 2 to get a whole number. Here's what I mean...
1/4 cup of apple juice = 1/2 cup of carrot juice
1/2 x 2 = 1 (whole number)
So, when we have a whole cup of carrot juice we have...
1/4 x 2 (since we multiplied the 1/2 by 2, we have to do the same to the other side).
1/4 x 2 = 1/2
David will use 1/2 cup of apple juice when he makes a cup of carrot juice.
Hope this helps :)

The function between the -4 and -1 is increasing and linear. Then the correct option is D.
What is a function?The function is an expression, rule, or law that defines the relationship between one variable to another variable. Functions are ubiquitous in mathematics and are essential for formulating physical relationships.
Describe the function between x = - 4 and x = -1.
As the value of x increases the value of the function also increases.
Then the function is an increasing function between -4 to -1.
Between -4 to -1 the function is a linear function.

The sum of the 1st nth term gp is 127.the sum of the reciprocal is 127/64,if the 1st term is 1.find n and the common ratio
Answer:
r=2,n=7
Step-by-step explanation:
The formula for the sum of the nth term of a Geometric Progression is given as:
Sn = a(1-r^n)/(1-r)
Where n = Number of terms
r = Common ratio
From the above question, we are told that:
The sum of the 1st nth term gp is 127.
Hence:
127 = 1(1-r^n)/(1-r)
We are also told that:
The sum of the reciprocal is 127/64
This means the inverse, the formula is given as:
Sn = 1/a(1-r^n)/(1-r)
127/64 = 1(1-1/r^n)/(1-1/r)
= r^(1-n)(1-r^n)/(1-r)
Solving the above, we obtain:
r^(n-1) = 64
r^(n-1) = 2⁶
Hence:
r = 2
Solving for n
n - 1 = 6
n = 6 + 1
n = 7
Therefore:
r=2,n=7

Remember. Slope is
a) 0

run (x2-x1)
c) undefined
b) 1/3
d) -3
Answer:
undefined
Step-by-step explanation:
( -4, 6) & (-4, -2)
To find the slope of the line, we use the slope formula: (y₂ - y₁) / (x₂ - x₁)
Plug in these values:
(-2 - 6) / (-4 - (-4))
Simplify the parentheses.
= (-8) / (-4 + 4)
= (-8) / (0)
Simplify the fraction.
-8/0
= undefined
This slope is undefined because you cannot divide a number by 0. These points also fall on a vertical line, which has an undefined slope.

The pic is attached.
Answer:
(-2, -4)
Step-by-step explanation:
The solution to a system of equations is an ordered pair. In order to be a solution to a system of inequalities, it has to be in the shaded area of both lines. Since both lines are shaded below the lines, the point has to be in that middle area where both the green and purple shades overlap. (-2, -4) is the only point in that picture that is in that overlapping shaded area. (-4, -1) is only in the green shaded area.
