Ok. First, let's find the slope using the slope formula.
[tex]m = \frac{y2-y1}{x2-x1} =\frac{9-5}{2-2} = 4/0[/tex]
4/0 is undefined.
When the slope is undefined, that means that it's a straight line going down from the x.
So the equation is just x = 2

There are 15 ice cream flavors and 3 different cone options. How many different 2 scoop cones can you make? (order doesn't matter and flavors can be repeated ie; chocolate on chocolate counts)
There are 675 different combinations.
How many combinations are there?The number of combinations is given by the product between the numbers of options.
For the first scoop, we have 15 possible options.For the second scoop, we also have 15 possible options.For the cone, we have 3 options.So the total number of different combinations is just given by:
C = 15*15*3 = 675

Write a Pythagorean triplet whose smallest member is 8
FAST
Answer:
Step-by-step explanation:
2m=8
m=4
m²+1=16+1=17
m²-1=16-1=15
Therefore the Pythagorean triplets are 8,15 and 17. Here 8 is the smallest member.
Answer: 8, 15, 17
This is something you get through trial and error, or you could have memorized this particular triple.
Note how 8^2+15^2 = 17^2

Tom walks 3. 15 km to the park. He then walks a further 350 m to the shop. How many km has Tom walked in total?
Answer:
Step-by-step explanation:
We have to convert m to km and we have to add to find the total distance walked.
1000m = 1 km
350 m = 350 ÷ 1000 = 0.35 km
Total distance = 3.15 + 0.35
= 3.50 km

of the tree. A right angle is created with the rope and the base of the tree. Using the
diagram below, how far up the tree did Mr. Jones tie the rope? Round your answer to
the nearest tenth.

AD10/12/20
Answer:
Step-by-step explanation:
To get how far up the tree that Mr. Jones tied the rope, we will use the Pythagoras theorem since a right angle is created with the rope and the base of the tree.
The length of the rope will be the hypotenuse
The distance up the tree and away from the base will be the opposite and adjacent.
Given
length of the rope = 8feet
Distance away from the base of the tree = 6ft
According to Pythagoras;
hyp² = opp²+adj²
8² = opp²+6²
opp² = 8²-6²
opp² = 64-36
opp² = 28
opp = 5.3 feet
Hence the Mr Jones tied the rope 5.3feet above the tree. Option C is correct

Slopes step by step
Answer:
1 is y=-1/3x. 3 is y=-3/2x. 5 is y=5/3x
Step-by-step explanation:
Simply count the vertical lengths. Meaning count up or down how ever many. That is your top number. Then count your horizontal lengths, meaning left or right, this your bottom number of the slope. So if point A is at (-1,-1) in example 1, then count down 1, and right 3 spaces. Because you go down, the slope is negative, and you went down 1, so the top number is 1, you went right 3 units, so the bottom number is 3.
what's better 27 out of 32 or 19 out of 21 and why
Answer:
19/21 is better.
Step-by-step explanation:
To find which is better, you need to divide the numerator by the denominator.
27 divided by 32 is equal to 0.84375
19 divided by 21 is equal to 0.9
0.9 is greater than 0.84375, so 19/21 is better.

A pizza place is having a special. If you order a large pizza for a regular price $17, you can order any number of additional pizzas for $8.50 each. Use the recursive rule f(1)=17 and f(n)=f(n-1)+8.5 for each whole number n greater than 1.
Answer:
Step-by-step explanation:
f(1)=17
f(n)=f(n-1)+8.5
n f(n)=f(n-1)+8.5 f(n)

Solve the inequality b - 12 > -3
What are the solutions?
Answer:
b>9
Step-by-step explanation:
Answer:
b > 9
Step-by-step explanation:
Inequalities represent the value of a variable in relation to other numbers.
Solving the Inequality
The properties of equality state that if you add or subtract a number from both sides, the statement remains true. This means that we can isolate the variable by using the properties of equality.
To isolate the variable, add 12 to both sidesThis gives the inequality b > 9Understanding the Answer
The answer to the inequality is b > 9. This means that the variable must be greater than 9. So, values such as 10 or 100 could all be solutions. However, remember that 9 itself is not a solution. The inequality only accounts for values greater than 9, not equal to.
