What is the slope of the line that passes through the points (9,5) and (21,1)? Write your answer in simplest form.
Answer:The slope of the line would be 1/3 because if you put those two coordinates in the table then you can see the the difference between 5 and 1 is 4 and the difference between 9 and 21 is 12 then do 4 divided by 12 and you get 1/3 for your slope.

Answer:
Triangle 6: 74
Triangle 7: 29
Triangle 8: 61
Triangle 9: 33
Step-by-step explanation:
Every triangle has a total degree angle of 180 degrees. Add the two sides that are known and subtract the sum from 180 degrees to find out the last angle.
Given P(A)=0.78P(A)=0.78, P(B)=0.65P(B)=0.65 and P(A\cup B)=0.873P(A∪B)=0.873, find the value of P(A\cap B)P(A∩B), rounding to the nearest thousandth, if necessary
Answer:
[tex]P(A\ n\ B) = 0.557[/tex]
Step-by-step explanation:
Given
[tex]P(A) = 0.78[/tex]
[tex]P(B) = 0.65[/tex]
[tex]P(A\ u\ B) = 0.873[/tex]
Required
Determine [tex]P(A\ n\ B)[/tex]
From laws of probability, we have:
[tex]P(A\ n\ B) = P(A) + P(B) - P(A\ u\ B)[/tex]
Substitute in values
[tex]P(A\ n\ B) = 0.78 + 0.65 - 0.873[/tex]
[tex]P(A\ n\ B) = 0.557[/tex]
Hence, [tex]P(A\ n\ B)[/tex] is calculated to be 0.557

What is the slope of the line that passes through (5, 4) and (7, 10) ?
A 3
B -3
C 2
D
-2
Answer:
3
Step-by-step explanation:
You would first plug in the points to the slope formula which is as follows:
m = y2 - y1 / x2 - x1
When you plug it in, it should look as follows:
m = 10 - 4 / 7 - 5
You should now add like terms.
m = 6/2
You should now simplify.
m = 3
Given f (x) = 2x² +1evaluate f (-1).
Answer:
3
Step-by-step explanation:
f(x) = 2x^2 + 1
f(-1) means that wherever you see an x on the right hand side, you substitute -1.
f(-1) = 2(-1)^2 + 1 = 2 + 1 = 3
What is the slope ? M=
Answer:
-3/2
Step-by-step explanation:
The slope is found by
m = ( y2-y1)/(x2-x1)
Using the points (-4,11) and ( 0,5)
m = ( 11-5)/( -4-0)
= 6/-4
= -3/2

PROBLEM : What is the slope of the line whose equation has the following solutions? Give an exact number.
Solution: x = -2.5 y= 0.5
Solution: x=2 y = 2
The slope is:
To find slope, we must use the slope formula*.
[tex]m = \frac{2 - 0.5}{2 - (-2.5)} = \frac{1.5}{4.5}[/tex]
The slope is 1.5/4.5.
How many solutions does this equation have? –7z − 7 = –4z + 8
Bryan is buying notebooks and pens at an office supply store. Notebooks cost $3.59 and pens cost $1.49. He can spend up to $13 on these items. Let x represent the number of notebooks. Let y represent the number of pens. Enter an inequality that represents the situation.
Answer:if the notebooks cost 3.59 and pens cost 1.49, with x representing the notebooks and y representing the number of pens and an amount of $13, the inequality would be written as 3.59x+1.49y13

Which point represents the quotient of 3-1?
A
B
C
D
The point that represents the quotient [tex]\frac{3 - i}{i}[/tex] is (C)
The quotient is given as:
[tex]Quotient = \frac{3 - i}{i}[/tex]
Rationalize the expression
[tex]Quotient = \frac{3 - i}{i} \times \frac ii[/tex]
Expand the above expression
[tex]Quotient = \frac{3i - i^2}{i^2}[/tex]
Evaluate all exponents
[tex]Quotient = \frac{3i - (-1)}{-1}[/tex]
Remove bracket
[tex]Quotient = \frac{3i +1}{-1}[/tex]
Rewrite the above expression as follows:
[tex]Quotient = -3i -1[/tex]
Further, rewrite as:
[tex]Quotient = -1-3i[/tex]
In the above expression, the real part is -1, and the imaginary part is -3.
This point is represented by point C, because:
[tex]C = (-1,-3)[/tex]
Hence, the point that represents the quotient [tex]\frac{3 - i}{i}[/tex] is (C)
