The trend line passes through (10,9) and (35,0). Write an equation for the trend line.
Answer: Solution :
Step 1 :
Make a scatter plot of Lily’s running data.
Step 2 :
To draw a trend line, use a straight edge to draw a line that has about the same number of points above and below it. Ignore any outliers.
Step 3 :
Find the slope of the trend line.
The line passes through points (2, 20) and (4.5, 45).
Use the slope formula.
m = (y2 - y1) / (x2 - x1)
Substitute x1, = 2, y1 = 20, x2 = 4, and y2 = 45.
m = (45 - 20) / (4.5 - 2)
m = 25 / 2.5
m = 10
Step 4 :
Find the y-intercept of the trend line.
Slope-intercept form equation of a line :
y = mx + b
Plug y = 20, m = 10 and x = 2.
20 = 10 · 2 + b
20 = 20 + b
Subtract 20 from both sides.
0 = b
Step 5 :
Use your slope and y-intercept values to write the equation.
Slope-intercept form equation of a line :
y = 10x + 0
So, the equation for the trend line is
y = 10x

The first equation in a system is 5x+2y=-4. Which equation gives a system with no solution.
Answer:
= 0.8 + -0.4y
Step-by-step explanation:
Simplifying
5x + 2y = 4
Solving
5x + 2y = 4
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-2y' to each side of the equation.
5x + 2y + -2y = 4 + -2y
Combine like terms: 2y + -2y = 0
5x + 0 = 4 + -2y
5x = 4 + -2y
Divide each side by '5'.
x = 0.8 + -0.4y

ASA Congruence Theorem
Suppose both factors in a multiplication problem are multiples of 10. Why might the number of zeroes in the product be different than the total number of zeroes in the factors?
Answer:
Multiplying factors whose products are multiples of 10 add to the number of zeros when factors are multiplied as multiples of 10s.
Step-by-step explanation:
Let the first five multiples of ten be
10*1= 10
10*2= 20
10*3=30
10*4=40
10*5= 50
Suppose we chose 20 and 50.
Now multiplying 20 with 50 we get
20*50= 1000
IF we count the total number of zeros in the factors ( 20 and 50) they are 2.
But the number of zeros in the product (1000) are 3.
This is because when we multiply 2 with 5 we get 10 which adds to the existing number of zeros ( i.e 2) and we get a total of 3 zeros.
And multiplying 10 with 50 we get
10*50= 500
IF we count the total number of zeros in the factors ( 10 and 50) they are 2.
But the number of zeros in the product (500) are also 2.
This is because when we multiply 1 with 5 we get 5 which does not add to the existing number of zeros ( i.e 2) and the total number of zeros remain the same.
Similarly multiplying 20 with 30 we get
20*30= 600
IF we count the total number of zeros in the factors ( 20 and 30) they are 2.
But the number of zeros in the product (600) are also 2.
This is because when we multiply 2 with 3 we get 6 which does not have a zero and the total number of zeros remain the same as in the factors.
So we see that multiplying factors whose products are multiples of 10 add to the number of zeros when factors are multiplied as multiples of 10s.

Find the value of x in the equation below 5= x/6
Answer:
x=30
Step-by-step explanation:
Answer:
x=30
Step-by-step explanation:
To find the value of x in an equation, our goal is always to isolate it so that it's on one side of the equal sign while everything else is on the other. We can do this by performing inverse operations to cancel values out (for example, the inverse operation of addition is subtraction and the inverse operation of division is multiplication).
5=x/6
Because x is being divided by 6, we multiply both sides by 6 to cancel it out on the side with x.
5×6=(x/6)×6
5×6=x
30=x

One page of a petition can hold p signatures. You were able to get 4p+5 people to sign the petition. Your friend was able to get 2p−3 people to sign the petition. Write an expression in simplest form that represents the number of people that you and your friend got to sign the petition.
Answer:
6p - 2
Step-by-step explanation:
The expression that needs to be made in this question refers to the total number of people that signed the petition. To calculate this we need to add the total number of signatures that both you and your friend were able to acquire. Once we do this we simply combine like terms in order to simplify the expression as much as possible.
4p + 5 + 2p - 3
4p + 2p + 5 - 3
6p - 2
Therefore, the total and simplified expression for the total number of signatures would be 6p - 2

Answer:
it says LESS THAN not less tha n or equal to so it cant be a or b or d, so it is c!
Step-by-step explanation:
Catherine bought apples and pears for the school picnic. If the total fruit is less than 100, then the correct equation for this will be y<100-x and y<x. Hence, option C is correct.

[tex]\frac{3}{2} x[/tex] - 2
Step-by-step explanation:
1/2 (2+ 3x -6)
1/2(3x-4)
3/2x - 2
You do the parentheses first because of PEDMAS. So 1 combined the 2 and the -6.
Answer:
The first answer (3/2x - 5)
Step-by-step explanation:
You need to multiply 1/2 by 2 which gives you 1. then when you multiply 1/2 by 3, you can't make it a whole number, so you make it a fraction and it then becomes 3/2x. Lastly, you do 1/2 times -6 which gives you -3. The equation goes from 1/2(2+3x-6) to then 1+3/2x-3. Since 1 and 3 can be subtracted because they're both whole numbers, you do 1-6 which gives you -5. The answer then becomes 3/2x -5

complete the statement of each of these rules:
a (+)×(?)=(+)
b (-)×(+)=?
c (?)×(-)=?
Answer:
a) (+) × (?) = (+)
(?) = (+)
b) (-) × (+) = ?
? = (-)
c) (?) × (-) = ?
? is undefined
Step-by-step explanation:
a) (+) × (?) = (+)
From the given equation in the question, by dividing both side of the equation by (+), we have;
((+) × (?))/(+) = (+)/(+)
(?) = (+)/(+) = (+)
Therefore, we have;
(+) × (+) = (+)
(?) = (+)
b) (-) × (+) = ?
From the given equation in the question we apply the operation rules as follows;
(-) × (-) = (+)
(-) × (+) = (-)
Therefore;
(-) × (+) = ? = (-)
? = (-)
c) (?) × (-) = ?
From the rules of multiplication, we have;
(-) × (-) = (+)
(+) × (-) = (-)
Therefore, when (?) = (-), ? = +, from which we have;
(?) ≠ ?, which is an error
Similarly, when (?) = (+), ? = -, therefore, (?) and ?, always changes sign
Therefore, the equation, (?) × (-) = ?, is undefined.
