[tex]y = ax + b[/tex]
[tex]1 = 4a + b \\ 3 = 3a + b \\ 2 = - a \\ a = - 2 \\ 1 = - 4 \times 2 + b \\ b = 1 + 8 = 9 \\ y = - 2x + 9[/tex]
Answer:
y=-2x+9
Step-by-step explanation:
From looking at the line you can already tell that the slope is going to be negative, and the y-intercept is going to be 9, since that's where y is when x is 0. You can see that when x is one, y is 7. When x is 2, y is 5. And when x is 3, y is 3.
So:
0: 9
1:7
2:5
3:3
And the difference of y over the difference of x is the slope
-2/1=-2
So the slope is -2
Therefore, putting the equation together makes:
y=-2x+9
Hope this helps!
What is the value of (u-t)(u^2-t^2)?
Answer:
20
Step-by-step explanation:
u-t = 2
u+t= 5
(u-t) (u²-t²)
(u-t) (u-t) (u+t) (a²-b²= (a+b) (a-b))
put the values
(2)(2)(5)
=20

Someone help ASAP plssss
Answer:
49
Step-by-step explanation:
you are given the hypotenuse of 60 and a leg of 35
a^2 + b^2 = c^2
35^2 + b^2 = 60^2
1225 +b^2 = 3600
-1225 -1225
2375
B^2 = square root 2375

Why would the end point for the function be (0,0)
Answer:
Yes, you are correct. It is (0,0)
Step-by-step explanation:
The lower left side of the curve hits the axis at 0,0 so you are correct. Try it
S = 365√x
Let x = 0
The square root of x when x = 0 is 0.
So S = 365√0
S = 0
Which is greater, 20% or 0.02?
Answer:
20% is greater
Step-by-step explanation:
0.02 is only 2%
Answer:
20%
Step-by-step explanation:
to change .02 into a percent, you move the decimal over twice or multiply it by 100. leaving it to be 2%
3y + x = 12
What is the value of x when y = 3?
Step-by-step explanation:
3y + x = 12
When y = 3, we have 3(3) + x = 12.
=> 9 + x = 12, x = 3.
FIND THE VALUE OF X.

Adam is buying some granola bars from the store. He finds a box of 6 Brain Grains granola bars for $4.74 and a box of 10 Nutty Crunch bars for $7.80. Which brand is the better value?
Answer: Nutty Crunch bars
Step-by-step explanation:
A box of 6 Brain Grains granola bars costs $4.74. The cost for one will be:
= $4.74 / 6
= $0.79
A box of 10 Nutty Crunch bars cost $7.80. The price per one will be:
= $7.80/10

-6=n/2-10 step by step one plz
Answer:
n = 8
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Multiplication Property of Equality Division Property of Equality Addition Property of Equality Subtract Property of EqualityStep-by-step explanation:
Step 1: Define
-6 = n/2 - 10
Step 2: Solve for n
Add 10 to both sides: 4 = n/2Multiply 2 on both sides: 8 = nRewrite: n = 8Step 3: Check
Plug in n into the original equation to verify it's a solution.
Substitute in n: -6 = 8/2 - 10Divide: -6 = 4 - 10Subtract: -6 = -6Here we see that -6 does indeed equal -6.
∴ n = 8 is the solution to the equation.

Ross has a season ticket.
In 2013 the season ticket cost £65.
In 2014 the cost of the ticket was increased by 8%.
In 2015 the cost of the ticket was increased by a further 5%.
Calculate the cost of the season ticket after the two price increases.
Answer:
£73.71
Step-by-step explanation:
Let's compute first for the cost of the ticket in 2014. Let x be the increase in the cost of the ticket. If the cost of the ticket is 8% of £65, then the expression should be like this:
x = 65 x 8%x = 65 x 0.08x = £5.2Let's add £5.2 to £65 ⇒ £5.2 + £65 = £70.2
The cost of the season ticket in 2014 is £70.2.
Next, we'll have to compute the cost of the ticket in 2015. Let y be the increase in cost of the ticket. If the cost of the ticket is 5% of £70.2, then the expression should be like this:
y = 70.2 x 5%y = 70.2 x 0.05y = £3.51Let's add £3.51 to £70.2 ⇒ £3.51 + £70.2 = £73.71
The cost of the season ticket in 2015 is £73.71. This is also the cost of the season ticket after two price increases.

Alicia drew a map of Texas. In the scale Alicia used for the map, .50 inch represents 20 miles. What is the distance between two cities on the map if the actual distance between the two cities is 360 miles?
Answer:
An actual distance of 360 miles correspond to 9 inches on the map
Step-by-step explanation:
From the question, we have a scale of 0.5 inches representing 20 miles
Now, we want to relate an actual distance of 360 miles to a measurement on the map using the scale
From here, we have that;
0.5 inches = 20 miles
x inches = 360 miles
x * 20 = 0.5 * 360
20x = 180
x = 180/20
x = 9 inches
OK so dont know srry bout that

By using regression line calculator,
Equation of the regression line from the data given,
y = -0.38993x + 26.95184
Here, y = weekly hours of sport
x = Time to run
For x = 50 minutes,
y = -0.38993(50) + 26.95184
= 7.45534
≈ 8
Since, slope of the given regression line is negative, correlation will be negative (n).
