Identify the coordinates of four points on the line with each given slope and y-intercept. slope = 2/3 and y-intercept = -5.........PLEASE ANSWER ASAP
The linear equation is y = (2/3)*x - 5, and the 4 points in the graph are:
{ (-1, -17/3), (0, -5), (1, -13/3), (2, -11/3)}
How to identify the points on the line?A linear equation written in the slope-intercept form is:
y = a*x + b
Where a is the slope and b is the y-intercept.
In this case, we have:
a = 2/3
b = -5
So our line is:
y = (2/3)*x - 5
To find the points, we need to evaluate the line in 4 different values of x.
We will use: x = -1, 0, 1, 2.
for x = -1 we have:
y = (2/3)*-1 - 5 = -2/3 - 5 = -17/3
So this gives the point (-1, -17/3).
for x = 0 we have:
y = (2/3)*0 - 5 = -5
So this gives the point (0, -5).
for x = 1 we have:
y = (2/3)*1 - 5 = -13/3
So this gives the point (1, -13/3).
for x = 2 we have:
y = (2/3)*2 - 5 = 4/3 - 15/3 = -11/3
So this gives the point (2, -11/3).
Then the 4 points are:
{ (-1, -17/3), (0, -5), (1, -13/3), (2, -11/3)}

The price of a camera is $ 9810 inclusive of sales tax. If the rate of sales tax is 9%, find the printed price of the camera.
Answer:
$8927.1
Step-by-step explanation:
printed price is the actual price without including tax price
tax price= 9/100×9810
tax price= 0.09×9810= $882.9
printed price of the camera= 9810-882.9= $8927.1

Hi!
We can see the river is a straight line.
This means that the angles that fall upon it are supplementary angles, and will add up to 180 degrees.
Therefore:
[tex]x+2x+21=180[/tex]
Combine like terms:
[tex]3x+21=180[/tex]
Subtract 21 from both sides:
[tex]3x=159[/tex]
Divide both sides by 3:
[tex]x=53[/tex]
Therefore, the value of x is 53 degrees.

Cooper has a points card for a movie theater. • He receives 70 rewards points just for signing up. • He earns 8.5 points for each visit to the movie theater. • He needs at least 260 points for a free movie ticket. Which inequality can be used to determine v, the minimum number of visits Cooper needs to earn his first free movie ticket?
FIRST TO ANSWER CORRECTY WILL BE MARK AS BRILLIANT !!!!
Answer:
The correct answer is 70+8.5V > 260
Step-by-step explanation:
The equation of this is that instead of getting 260 points instantly he can get to 23 movies and earn the points each visits. So
8.5x23+70=265.5
Hence the correct answer is C

Any one help I will mark u as BRAINLIEST ANSWER if u help me plssssss! I will not accept wrong answer pls
Answer:
15 answers
Step-by-step explanation:
To solve this question we need to set up an equation.
Let's name the number of incorrect answers x.
We can set up an equation that's essentially:
(Points for correct answer)*(number of correct answers)+(points for incorrect answer)*(number of incorrect answers)=final score
When we plug in our numbers and variables it looks like this:
5(3)+(-2x)=-15
Simplify
15-2x=-15
Subtract 15 from both sides
-2x=-30
Divide both sides by -2
x=15
This means Smitha attempted 15 wrong answers, and that there were 18 questions in total.

3) If the speed limit on a highway in the UK is 70 miles per hour and
it is 120km per hour in Canada, which country has the higher speed
limit for highways? What is the difference between them?
Step-by-step explanation:
for this we need to know the conversion rate between miles and kilometers :
1 mile = 1.60934 km
which means
1 km = 0.621371 miles
so,
70 m/h = 70×1.60934 km/h = 112.6538 km/h
compared to the 120 km/h limit in Canada, it is clear that the speed limit in Canada is higher.
the difference is
7.3462 km/h = 7.3462×0.621371 = 4.56471564 m/h
The function C(t)=100*e^-0.000121t describes how to find the percentage of carbon-14, C(t), remaining in an object after t years. According to this information, what was the percentage of carbon-14 remaining in an object after 55 years? (Round your answer to the nearest hundredth.)

given the following exponential function identify whether the change represents growth or decay y= 56(0.91)^x
Answer:
Decay
Step-by-step explanation:
Any "r" value between 0 and 1 indicates an exponential function in decay. The "r" value is the one in the parentheses and raised to the exponent. In this case, the value is 0.91. This number falls within the "r" value boundaries of a decaying exponential function.

If f(x) is an exponential function where f(2)=23 and f(3)=58, then find the value of f(6), to the nearest hundredth.
The exponential function is given as 3.68 × (2.52)ˣ. Then the value of function at x = 6 will be 942.43.
What is an exponent?The exponent denotes that the base will rise to a specific level of strength. The base is X, and the power is n.
If f(x) is an exponential function where f(2) = 23 and f(3) = 58.
Then the exponential function will be
f(x) = abˣ
If f(2) = 23, then we have
23 = ab² ...1
If f(3) = 58, then we have
58 = ab³ ...2
Then from equations 1 and 2, we have
a = 3.62 and b = 2.52
Then the function will be
f(x) = 3.68 × (2.52)ˣ
Then the value of f(6) will be
f(6) = 3.68 × (2.52)⁶
f(6) = 3.68 × 256.1
f(6) = 942.43
