Answer:
h(x) = 10y/2
Step-by-step explanation:
6x + y = 4x + 11y
6x - 4x = 11y - y
2x = 10y
divide both side by 2
x = 10y/2
h(x) = 10y/2

The scale factor of a room for a scale drawing is 2.3. The actual length of a wall in the room is 46 feet and the actual width of the room is 69 feet. What is the area of the scale drawing?
50 square feet
500 square feet
600 square feet
1380 square feet
PLEASE HELP ME!!!!!!!
Answer:
There's two ways to solve this.
Step-by-step explanation:
First way:
Let's divide the width and length by 2.3.
46÷2.3=20
69÷2.3=30
20×30
600 ft²
Second Way:
Let's find the area of the actual room.
46×69
3,174 ft²
Let's find the scale drawing squared.
2.3²=5.29
3,174÷5.29
600 ft²
Answer:
600

Answer:
B. p varies inversely as r
Step-by-step explanation:
Since, p varies directly as q
[tex] \therefore p\:\:\alpha \:\:q\\
\therefore p= kq.. (k = constant)... (1)\\
[/tex]
Since, q varies inversely as r
[tex] \therefore q\:\:\alpha \:\:\frac{1}{r} \\
\therefore q= \frac{k}{r} .. (k = constant)... (2)\\
[/tex]
From equations (1) & (2)
[tex] p = k\times \frac{k}{r}\\
p = \frac{k^2}{r}\\
p\:\:\alpha \:\: \frac{1}{r}\\
[/tex]
Hence, p varies inversely as r.
Kenji earned the test scores below in English class. 79, 91, 93, 85, 86, and 88 After his next test, his mean and median scores both change to 88. How much does he earn on this test?
Answer:
Step-by-step explanation:
We need to find what number he got on the test.
We know he got a bigger number than 88.
79+85+86+88+91+93+x.
Let's substitute x for 94.
79+85+86+88+91+93+94/2 = 88.
Since any other number thats near 94 doesn't equal 88, we know that this is exactly the right answer.
Which relation is also a function?
Answer:
Step-by-step explanation:
A relation from a set X to a set Y is called a function if each element of X is related to exactly one element in Y. That is, given an element x in X, there is only one element in Y that x is related to. For example, consider the following sets X and Y.
When we say about relation is a function
The given table relation is not a function
the graph relation is not a function
Given :
A relation is a function when all x values has exactly only one y value .
Each input has only one output for a function .
When x values are repeated then we can say that there is two output .
So that is not a function .
In the given table, we have x=5 repeated twice .
when x=5 there are two outputs [tex]-3 and -2[/tex]
for x=5, there are two outputs.
The given table relation is not a function
Now we consider the graph
When x=2 , there are 2 y values [tex]-3 \; and \; -4[/tex]
So input 2 has two output values
Hence , the graph relation is not a function

find the area of the figure
Answer:
90 inches squared
Step-by-step explanation:
To do this you would first find the area of the 2 triangles shown on the side so we would do 5 times 2 divided by 2 since that is how we solve this problem so we would get 5 inches squared for the 2 triangles then we would find the area of the square which is 100 since it is a 10 by 10 then you would subtract 5+5 by 100 which is 90 so 90 inches squared would be the answer
Answer:
Your correct answer is 90 sq. in.
Step-by-step explanation:
Find the area of the 2 triangles that are shown on the side.
5 x 2 divided by 2 = 5 sq. in.
Now, find the area of the square
The answer for this is 100 because it is a 10 x 10
Next, subtract
5 + 5 by 100 = 90

A farmer picks 242 apples on Monday and 118 apples on Tuesday. On Wednesday, she sells 109 of the apples at the market. Which equation can be used to find a, the number of apples the farmer has left? 242 - 118 - 109 = a 242 - 118 + 109 = a 242 + 118 - 109 = a 242 + 118 + 109 = a
Answer:
242 + 118 - 109
Step-by-step explanation:
collected- 360 apples total ( 242 + 118 )
sold- 109 apples

8. Find the equation of a line in slope intercept form that is parallel to the line y = -2x - 3 that goes
through the point (2, 1).
Work:
Answer:
Step-by-step explanation:
Hey there!!
To solve this type of question, use these steps.
Find these 1st equation by using one point formula of point.After this from equation 2 find slope, by comparing it with y= mx + c if it is in slope intercept form. Then, as per the conditions of parallel lines, use m1=m2, then put the value of m1 in equation 1st.Then simplify them.So, let's work with these steps.
Now,
The equation of a st.line passing through point (2,1) is,
[tex](y - y1) = m1(x - x1)[/tex]
Put all values.
[tex](y - 1) = m1(x - 2)[/tex]
It is the 1st equation.
Another equation is,
y = -2x -3.......(ii)
Comparing the equation with y = mx+c.
Therefore, from equation (ii)
m2 = -2
Now, as per condition of parallel lines,
m1=m2= -2
Putting the value of m1 in equation 1st.
[tex](y - 1) = - 2(x - 2)[/tex]
y - 1 = -2x + 4
y = -2x +5.
Therefore, the equation is y = -2x +5.
Hope it helps...

A ship must be unloaded by two cranes in 12 hours. Both cranes worked for 8 hours and then one of them broke. The rest of the work was done by the other crane in 7 hours. How long would each crane take to do the entire job if it was working alone? Thank you!
Answer:
6 hours
Step-by-step explanation:
8 hours x 2 cranes = 16 hours of total work
After one broke
7 hours x 1 crane = 7 hours of total work
16 + 7 = 23 hours
It would take 23 hours for one crane to do the whole job.
