Answer:
(21, 8)
(3, 2)
(-15, -4)
Step-by-step explanation:
First we need to create the equation in y=mx +b form.
(m) is slope [rise/run]
(b) is y intercept
The line crosses the y axis at (0,1) so that's our (b) and to find slope we will find a point where ethe line crosses a point, I'll use (0, 1) and see how many it has to go to reach the next point. In this case it has to go up 1, and right 3.
Our slope is 1/3.
y=1/3x+1.
Now we can start applying the given points.
(21, 8)
8=1/3(21)+1
8=7+1
8=8.
(21, 8) is a solution.
(3, 2)
2=1/3(3)+1
2=1+1
2=2
(3, 2) is a solution.
(-15, -4)
-4=1/3(-15)+1
-4=-5+1
-4=-4
(-15, -4) is a solution.
(12, 9)
9=1/3(12)+1
9=4+1
9=5
(12, 9) is not a solution.
(-6, 1)
1=1/3(-6)+1
1=-2+1
1=-1
(-6, 1) is not a solution.
Hope this helps! If you have any questions on how I got my answer feel free to ask. Stay safe!

Answers
1. Answer/Step-by-step explanation:
Diving question: 0 - 35.25 + -8.5 = -43.75 below sea level
Baking question: insolvable by lack of information.
2. Answer/Step-by-step explanation:
A money decrease of $60.50 (or -60.50 increase and change)
? - 45 - 30.15 + 14.65 = -60.50
Since we are finding the change it is best to replace the question mark with 0 so that it is easier to solve.
0 - 45 = -45
-45 - 30.15 = -75.25
-75.25 + 14.65 = -60.50

Answers
Answer:
Step-by-step explanation:
I'm assuming you're not doing the pre-calculus version of this equation where your angle is in radians. So we'll do the Geometry version which looks like this:
[tex]AL=\frac{\theta}{360}*2\pi r[/tex]
Our angle is 30 and our radius is 4, so we fill in accordingly:
[tex]AL=\frac{30}{360}*2(3.1415)(4)[/tex] (this is if you multiply in pi. We'll find the answer in terms of pi as well).
AL = [tex]\frac{1}{12}*25.132[/tex] and
AL = 2.09433 inches
In terms of pi, the answer would be
AL = [tex]\frac{2}{3}\pi[/tex] inches

The value of 196 ÷ 3.5 is 56
What is division?Division is the opposite of multiplication. If 3 groups of 4 make 12 in multiplication, 12 divided into 3 equal groups give 4 in each group in division. The main goal of dividing is to see how many equal groups are formed or how many are in each group when sharing fairly.
For example, if 50 apples are to be shared by 5 people , the number of apples allocated bto a person is 50/5 = 10 apples
196/3.5
to solve the we can multiply the numerator and denominator by 10 to make all whole number
= 1960/35
we can now simplify
divide through by 5
392/7
divide through by 7
= 56
therefore the value of 196/3.5 is 56

Kaley's family drove to DisneyLand for spring break. Her mom and dad shared the driving duties for a total of 24 hours. Her mom drove 75 miles per hour, and her dad drove 60 miles per hour. If they drove a total of 1,710 miles, how many hours did each person drive for?
Answers
Answer:
Mom drove for 18 hours.
Dad drove for 6 hours.
Step-by-step explanation:
Given that:
Number of hours for the driving duty = 24 hours
Speed at which the mom drove = 75 miles per hour
Speed at which the dad drove = 60 miles per hour
Total distance driven by both of them = 1710 miles
To find:
Number of hours for which each person drive for ?
Solution:
Let number of hours driven by dad = [tex]x[/tex] hours
Let number of hours driven by mom = (24 - [tex]x[/tex]) hours
Let us have a look at the formula for Distance in terms of Speed and Time.
[tex]Distance = Speed \times Time[/tex]
Distance traveled by Mom = [tex]75 \times x =75x \ miles[/tex]
Distance traveled by dad = [tex]60(24-x) =144-60x[/tex] miles
As per question statement:
[tex]75x+1440-60x=1710\\\Rightarrow 15x=1710-1440\\\Rightarrow 15x = 270\\\Rightarrow x = 18\ hours[/tex]
So, Mom drove for 18 hours.
Dad drove for 6 hours.
