Answer: Linear
The equation is y = 2x-5
Slope = 2
y intercept = -5
====================================================
Explanation:
Each time x goes up by 1, y increases by 2. This directly leads to a linear equation due to the same rate of change no matter where you are in the table.
The slope is rise/run = 2/1 = 2 because "y increases by 2 each time x increases by 1".
We could use the slope formula to see this. Pick on any two rows to plug in the coordinates. I'll use the last two rows
m = (y2-y1)/(x2-x1)
m = (3-1)/(4-3)
m = 2/1
m = 2
This confirms the slope is 2.
The positive slope means that the line goes uphill as you move from left to right.
---------------
The y intercept is b = -5 because the y intercept always happens when x = 0. This applies to any function, whether it's linear or not.
Together with m = 2 as the slope and b = -5 as the y intercept, we go from y = mx+b to y = 2x-5 as our linear equation
As a way to check, plug in something like x = 1 to find that...
y = 2x-5
y = 2*1-5
y = 2-5
y = -3
The table shows that x = 1 and y = -3 pair up together in the same row, so that confirms x = 1. I'll let you verify the other x values.

On Monday, Richard worked for 4 hours and earned $36. On Tuesday, Richard worked for 6 hours and earned $54. On Wednesday, Richard worked for 5 hours and earned $45. what is the rate of his earnings? Represent his earnings in a y=mx function, where hours are represented by y, and m represents the rate of change. If richard worked for 7 hours, how much money would he earn? How many hours did richard work on friday, when he earned $81
Answer:
Earnings (E), Time (T) Rate (R) E = 9t
On Friday he worked 9 hours
Step-by-step explanation:
divide 36 by 4 to get 9 (Fo that for all the earnings to make sure you got the correct answer) Then just divide 81 by 9 to get 9 hours.

Solve log 2x^2 + 2 = 6. Round to the nearest thousandth if necessary.
Answer:
x = 70.71
Step-by-step explanation:
log 2x² + 2 = 6.
log 2x² + log 100= log 10⁶.
2x² × 100 = 10⁶
2x² = 10⁶/100
2x² = 10⁴
x² = 10⁴/2
x² = 5000
x = √5000
x is approximately 70.71
x = 70.71
10. Solve for x akoajssbsbqn
Answer:
x = 5
Step-by-step explanation:
10 * 7 = x * 14
10 * 7 = 70
14 * x = 14x
14x = 70
divide each side by 14
14x / 14 = x
70 / 14 = 5
we're left with x = 5
bro i keep getting it wrong so can you please tell me how to solve this not just the answer
Answer:
A
Step-by-step explanation:
since it is on sale for 27%, multiply $28 by 70% (0.7) to find the total amount of money the shirt costs now that it is on sale (since it's on sale for 30% off)
$28*0.7=$19.60
Answer:
$19.60
Step-by-step explanation:
First, find 30% of $28. :)
To do this, multiply 28 by 0.3. (30% is the same thing as 3/10 or 0.3)
28 x 0.3 = 8.4.
30% of 28 is 8.4.
Next, subtract $8.4 from $28. (Shirt on sale for 30% off)
28 - 8.4 = $19.60
Have a great day!

Luna Lovegood is making smoothies for the Ravenclaw students. She combines two and a half quarts of orange juice, four and a half pints of milk, and 5 cups of pineapple juice to make the smoothies. How many cups of smoothie does Luna make? *
Answer: Luna Lovegood made 24 cups of smoothie.
Step-by-step explanation: We have to convert the measurements to cups.
Orange Juice:
2 1/2 quarts converted to cups is 10 cups.
2 1/2 or 2.5 multiplied by 4 equals to 10
Milk:
4 1/2 or 4.5 pints converted to cups is 9 cups.
You have to do 4.5 times 2 to get 9.
Pineapple Juice:
5 cups. Since it's already been converted we don't do anything to convert.
Lastly, we add.
10+9+5=24 cups.
Answer:
Let me go ask LunaLovegood555..... she's good at making smoothies.
Step-by-step explanation:
She said 24 cups/smoothies.
What does x=_____ degrees
Answer:
x = 48 degrees
Step-by-step explanation:
This triangle is an isosceles which means that two of the angles are the same and all triangles add up to 180 degrees so we take the two angles we know and add them
66 + 66 = 132
Then we subtract that number from 180 to find the third angle
180 - 132 = 48
Answer:
x = 48°
Step-by-step explanation:
Since the legs of the triangle are congruent then the base angles are congruent, both 66° , then
x = 180° - (66 + 66)° = 180° - 132° = 48°

I need some help finding the volume of a sphere with a diameter of 18.6cm. The website says the answer I got from my calculator was wrong! Help would be greatly appreciated!
Answer:
V ≈ 3367.6 cm³
Step-by-step explanation:
The volume (V) of a sphere is calculated as
V = [tex]\frac{4}{3}[/tex] πr³ ( r is the radius )
Here D = 18.6 , then r = 18.6 ÷ 2 = 9.3 , so
V = [tex]\frac{4}{3}[/tex] × 3.14 × 9.3³
= [tex]\frac{4}{3}[/tex] × 3.14 × 804.357
= [tex]\frac{4(3.14)(804.357)}{3}[/tex]
≈ 3367.6 cm³ ( to the nearest tenth )
is 9e+2(e+5) and 11e+5 equivalent?
No,
[tex]9e + 2(e + 5) = 11e + 10[/tex]
And 11e + 10 is not equivalent to 11e + 5
Answer:
No, its not.
9e + 2(e+5)
= 9e + 2e + 10
= 11e + 10
---> 9e+2(e+5) when simplified gives 11e + 10.
---> Therefore, its not equal to 11e + 5

Team D's car went the same distance on each of its trials. Team C's car went exactly 1 cm farther in each trial than Team D's car. Team C's car went 543 cm in all.
Answer:
180 cm
Step-by-step explanation:
Number of trials per team = 3
Distance per trial for team D's car is the same for each trial, let distance = x
Distance per trial for team C's car is 1cm farther than team D's distance and the same for each trial, hence, distance = x + 1 per trial
Total distance traveled by C = 543 cm
This means :
(x + 1) + (x + 1) + (x + 1) = 543
3x + 3 = 543
3x = 543 - 3
3x = 540
x = 540 / 3
x = 180
Hence, distance traveled per trial for team D's car = x = 180 cm
Susan has a weight of 40.65 kilograms. Adam is 4.3 kilograms heavier than Susan, and James is 2.9 kilogram lighter than Susan. What are the weights of Adam and James combined?Immersive Reader
Answer:
82.7kg
Step-by-step explanation:
wdym by immersive reader?
Answer:
82.7kg
Step-by-step explanation:
We know that Susan is 40.65kg. If Adam weighs 4.3kg more than Susan, it means that he weighs 40.65+4.3 = 44.95kg
James is 2.9kg lighter meaning he is 40.65-2.9 = 37.75kg
Now that we know that weights of Adam and James (44.95 and 37.75). we can add them together to get the combined weight: 44.95 + 37.75 = 82.7kg
Hope this helped!
