To find slope, we need two points. Once we have them, we can put them into the formula:
[tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex] ← this is rise/run
For 7, it's just a matter of comparing any two consecutive points.
For 8, you are given the two points.
Why is 3^-2 not a negative number?
The rule you use is x^(-k) = 1/(x^k)
In this case x = 3 and k = 2, so,
3^(-2) = 1/(3^2) = 1/9
--------------------------------------------
One way to think of it, is to consider the equation below
3^2*3^x = 1
We can solve for x like this
3^2*3^x = 1
3^(2+x) = 1
3^(2+x) = 3^0
2+x = 0 .... the bases are equal, so the exponents must be equal
x = -2
meaning that
3^2*3^x = 1
updates to
3^2*3^(-2) = 1
Now isolate the 3^(-2)
3^2*3^(-2) = 1
3^(-2) = 1/(3^2)
3^(-2) = 1/9

Answer:
GCF is Greatest Common Factor.
Explaination:
The greatest common factor (GCF) of a set of numbers is the largest factor that all the numbers share. For example, 12, 20, and 24 have two common factors: 2 and 4. The largest is 4, so we say that the GCF of 12, 20, and 24 is 4.

Let the function f be defined by f(x) = 12-5x
What value of a will make the equation f(a) = 6 true?
6/5
-18
-13
5/6
Answer:
6/5
Step-by-step explanation:
given that f(a) = 6
using x = a
f(x) = 12-5x
f(a) = 12 - 5a
since f(a) = 6
6 = 12 - 5 a
6 - 12 = 12 - 5a - 12
= -6 = -5a
= -6/-5 = -5a/-5
= a = 6/5
value of a is 6/5

3(x-4)= 36
Answer:
x = 16
Step-by-step explanation:
3(x-4)=36
First we will distribute:
3x - 12 = 36
Add 12 to both sides:
3x = 48
Divide both sides by the coefficient:
x = 16
Check your work:
3 (x - 4) = 36
3 (16 - 4) = 36
3 (12) = 36
36 = 36
Final answer:
x = 16

Step-by-step explanation:
Answer
x=[tex]\frac{\sqrt{45} }{5}[/tex]
Step-by-step explanation:
1) add 45 to both sides
5x^2=45
2) square root both sides
5x=[tex]\sqrt{45[/tex]
3) Divide both sides by 5
x=[tex]\frac{\sqrt{45} }{5}[/tex]

Carolyn has 20 biscuits in a tin.
She has
12 plain biscuits
5 chocolate biscuits
3 ginger biscuits
Carolyn takes at random two biscuits from the tin.
Work out the probability that the two biscuits were not the same type.
4 Marks
Answer:
Approximately 58.4%
Step-by-step explanation:
The probability that they are different is the opposite of the probability that they are the same.
The probability that they are the same is:
P(plain, plain) = (12/20) (11/19) = 132 / 380
P(chocolate, chocolate) = (5/20) (4/19) = 20 / 380
P(currant, currant) = (3/20) (2/19) = 6 / 380
P(same) = 132/380 + 20/380 + 6/380
P(same) = 158/380
P(same) = 79/190
Therefore, the probability that they are different is:
P(different) = 1 − 79/
[tex]\frac{111}{190}[/tex] is the probability that the two biscuits were of not the same type.
What is Probability?
Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates impossibility of the event and 1 indicates certainty.
According to question, Carolyn has 20 biscuits in a tin.
She has 12 plain biscuits, 5 chocolate biscuits and 3 ginger biscuits
Carolyn takes at random two biscuits from the tin.
We have to find out the probability that the two biscuits were of not the same type.
P(plain biscuit, plain biscuit) [tex]=(\frac{12}{20} )(\frac{11}{19} )=\frac{132}{380}[/tex]
P(chocolate biscuit, chocolate biscuit)[tex]=(\frac{5}{20})(\frac{4}{19} )=\frac{20}{380}[/tex]
P(ginger biscuit, ginger biscuit)[tex]=(\frac{3}{20}) (\frac{2}{19})=\frac{6}{380}[/tex]
Probability of same type of biscuits
[tex]=\frac{132}{380} +\frac{20}{380}+\frac{6}{380}[/tex]
[tex]=\frac{79}{190}[/tex]
The probability that the two biscuits were not of the same type.
[tex]=1-\frac{79}{190}[/tex]
[tex]=\frac{111}{190}[/tex]
Hence, we can conclude that [tex]\frac{111}{190}[/tex] is the probability that the two biscuits were not of the same type.

you will have 8 baskets
because if you look at all the number you will see that they have one number in common which is eight. then you will need to find the division partner which would be:
4 sanwiches,5 granola bars,and 6 apples in one picnic basket. doing that you will get eight basket in total.
A directed segment QR¯¯¯¯¯ with endpoints at Q (2, 1) and R (8, 13) is partitioned from Q to R into a 1:2 ratio at point Z. What are the coordinates of Z?
(2, 4)
(4, 5)
(6, 9)
(9, 10)
Answer:
The coordinate of the point Z is (4, 5)
Step-by-step explanation:
The given information are;
The coordinates of the endpoints of the directed segment QR are Q(2, 1) and R(8, 13)
The ratio of the partition of the directed line segment QR from Q to R = 1:2
The location of the point at the directed line segment is partitioned = Point Z
Therefore, we have;
The proportion of the partition segment QZ to QR is given as follows;
QZ = 1/(1 + 2) × QR = 1/3·QR
ZR = 2/(1 + 2) × QR = 2/3·QR
Which gives the coordinate of the point Z as follows;
The coordinate of the point Z = (2 + (8 - 2)×1/3, 1 + (13 - 1)×1/3)
The coordinate of the point Z = (2 + 2, 1 + 4) = (4, 5)
The coordinate of the point Z = (4, 5).
