Answer:
10 over 11
Step-by-step explanation:
Y2 minus Y1 over X2 minus X1
Answer:
10/11 or 10 over 11 rise
Step-by-step explanation:
Slope formula: (y2 - y1) / (x2 - x1)
(-20 - 0) / (-14 - 8)
(-20) / (-22)
= 10/11
(9,18)(4,3) find the slope
Answer:
m (slope) = 3
Step-by-step explanation:
Slope is equal to the change in y over the change in x, or rise over run.
m= 3-(18) / 4-(9)
simplify
m=3

One number is seven more than six times another number. If the sum of the numbers is 21, find the numbers
Answer:the two numbers are 2 and 19
Step-by-step explanation:
Let one of the numbers be x
and the second be 7+ 6x
so that the sum of the two numbers which totals 21 be expressed as
x + (7+ 6x) = 21
x+ 7+6x= 21
7 + 7x = 21
7x= 14
x= 14/7 = 2
one of the numbers = 2
the other number given as
7+ 6x = 7+ 6 x 2= 7+12= 19
The numbers are 2 and 19 .
The numbers as described in the question are; 2 and 19
Solving word problemsFrom the given problem statements;
The first number = y
The second number = x
Hence, y = (7 + 6x)
Their sum is therefore;
x + 7 = 6x = 217x = 14x = 2Hence, the second number is; 7 + 6x = 7 + 6(2);
y = 19Read more on word problems;

What is the intercept of
y=-1/2x-1 and y=1/4x-4
Answer: The y-intercept of y = -1/2x -1 is (0,-1)
The y-intercept of y = 1/4x -4 is (0,-4)
The attachment shows the graph of these equations.
Step-by-step explanation:
Both equations are in slope-intercept form. y = mx + b
The constant, b, is the y-intercept.
The y-intercept of y = 1/2x -1 is (0,-1)
The y-intercept of y = 1/4x -4 is (0,-4)
What is y- intercept?On a graph, the y-intercept can be found by finding the value of y when x=0. This is the point at which the graph crosses through the y-axis.
Given:
y=-1/2x-1 and y=1/4x-4
For Finding the y- intercept put x= 0 we get
y = -1/2(0) -1
y= 0- 1
y= -1.
For Finding the y- intercept put x= 0 we get
y=1/4(0)-4
y= 0- 4
y= -4

Find the 18h term of the arithmetic sequence whose common difference is d=4 and whose first term is a, =3.
Answer:
the 18th term is 71
Step-by-step explanation:
The general form for any term "n" in an arithmetic sequence is:
a(n) = a1 + (n-1) * d
where "d" is the common difference.
So, in our case we have:
a(n) = 3 + (n-1) *4
Therefore, the 18th term will be:
a(18) = 3 + (18 - 1) 4 = 3 + 17 * 4 = 71

your family went out to dinner to celebrate your grandmas 100th birthday. The total for the dinner was $208.60, so your parents left a $31.29 tip. What percent of the bill was the tip?
Answer:
[tex]\%Tip = 13.04\%[/tex]
Step-by-step explanation:
Given
[tex]Tip= \$31.29[/tex]
[tex]Bill = \$208.60[/tex]
Required
Determine the percentage of the tip
First, we calculate the amount paid
[tex]Amount = Tip + Bill[/tex]
[tex]Amount = \$31.29 + \$208.60[/tex]
[tex]Amount = \$239.89[/tex]
The percentage of the tip is then calculated using:
[tex]\%Tip = \frac{Tip}{Amount} * 100\%[/tex]
[tex]\%Tip = \frac{31.29}{239.89} * 100\%[/tex]
[tex]\%Tip = \frac{31.29* 100}{239.89} \%[/tex]
[tex]\%Tip = \frac{3129}{239.89} \%[/tex]
[tex]\%Tip = 13.04\%[/tex]
