The slope of the graph of the equation of the line as 5x - 2y = 20 will be [m] = 5/2
What is the general equation of a Straight line?The general equation of a straight line is -
[y] = [m]x + [c]
where -
[m] is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.
The equation of a straight line can be also written as -
Ax + By + C = 0
By = - Ax - C
y = (- A/B)x - (C/A)
Given is the equation of the line as 5x - 2y = 20.
We have the equation of the line as -
5x - 2y = 20
2y = 5x - 20
y = (5/2)x - 10
[m] = 5/2
Therefore, the slope of the graph of the equation of the line as 5x - 2y = 20 will be [m] = 5/2

For reason 3, look at how we got from step 2 to step 3.
In this case, we combined like terms or simplifies the left side.
So the reason for statement 3 is simplifying.
For statement 4, we look at how we got from step 3 to step 4.
Notice that we subtracted the same quantity, -12x, from both sides of the
equation and this is the subtraction property of equality.
For statement 5, we look at how we got from step 4 to step 5.
Here, we added the same quantity to both sides
and this is called the addition property of equality.
Finally, we use the division property of equality,
to get the final solution to the equation, x = 2/3.
If 9x + 80= 890 then what is x?
I'm taking a test tomorrow but I'm bad at this stuff. Please help me!
Answer:
x = 90
Step-by-step explanation:
9x + 80 = 890 ( subtract 80 from both sides )
9x = 810 ( divide both sides by 9 )
x = 90

The circle graph shows the results of a survey by a bakery on which of their new products 69 customers preferred most. How many customers preferred bread? Round your answer to the nearest whole number.
The circle graph is used to show the preference of each customer
32 customers preferred bread
How to determine the number of customers?From the question, we have:
Bread = 47%
Total customers = 69
So, the number of customers that preferred bread is:
Bread = 47% * 69
Evaluate the product
Bread = 32.43
Approximate
Bread = 32
Hence, 32 customers preferred bread

A booth at the circus is taking donations for the children's hospital. They noticed on Saturday that more than 217 people donated money. Women averaged a donation of $18, and men averaged a donation of $16. Which system of inequalities could be used to determine the number of women (w) and men (m) who donated, if no more than $3,702 was donated?
Answer:
Step-by-step explanation:
Let M be the number of men donors and W the number of women donors.
We are told that M + W => 217 {"They noticed on Saturday that more than 217 people donated money."]
The total donations of no more than $3,702 consists of Men: ($16)M and Women: ($18)W
This makes the following equation:
18W + 16M <= 3702 ["no more than $3,702 was donated"]
The two equations are:
18W + 16M <= 3702, and
M + W => 217
=====
Extra credit:
To find the number of men and women donors, let's assume the equations are correct without the inequality signs.
Rearrange:
M + W => 217
M = 217-W
Now use this definition of M in the second equation:
18W + 16(217-W) = 3702
'
Solve for W: W = 115: There were 115 women donors at $18 each: $207.
That means 217 - 115 or 102 men at $16 each: &1632
Total donations of $3702
a pharmacist found at the end of the day she had 7/4 as many prescriptions for antibiotics as tranquilizers. she had 77 prescriptions altogether. how many did she have for tranquilizers?
Answer:
44 tranquilizers
Step-by-step explanation:
The reciprocal of 7/4 is 4/7 so if you multiply 77 by 4/7 you will get 44.

If the diagonals in a rhombus are 8 and 6 then the perimeter is
a) 16
b) 18
c) 20
d) 22
Answer:
20 (units)Step-by-step explanation:
If the diagonals in a rhombus are 8 and 6 then the perimeter is
a) 16
b) 18
c) 20
d) 22
the regular rhombus is formed by 4 right triangles, 1/2 of the diagonal is the cathetus.
8 : 2 = 4
6 : 2 = 3
find with Pythagoras the side of the rhombus
s = √(4² + 3²)
s = √(16 + 9)
s = √25
s = 5
now we find the perimeter by adding the 4 sides
5 + 5 + 5 + 5 = 20

Name the property that each statement illustrates. You buy a sandwich for $2.95, an apple for $.45, and a bottle of juice for $1.05. What is the total cost?
Answer:
The total cost is $4.45
Step-by-step explanation:
I just added them
Step-by-step explanation:
let a= cost of sandwich=2.95dollars
b=cost of apple= 0.45dollars
c= cost of juice= 1.05 dollars
then t= total cost is calulated as:
t=a+b+c
t=2.95+0.45+1.05
t=4.45

What is an right angle and abtuce angle
Answer:
An right angle is an angle which is 90 degrees and obtuse angle which is greater than 90 degrees. There’s also an acute angle which is shorter than 90 degrees.
Step-by-step explanation:
What is a right angle and obtuse angle?
Answer: A right angle is defined as a 90-degree angle.
Step-by-step explanation:
A right angle in trigonometry is an angle of approximately 90 degrees or /2 radians, which corresponds to a quarter turn. Right angles are formed when the endpoint of a ray is on a line and the adjacent angles are equal.
Answer: An angle that is greater than 90 degrees but less than 180 degrees is called an obtuse angle.
Step-by-step explanation:
The smaller angle is the obtuse angle. It is greater than 90 degrees but less than 180 degrees.
