Answer:
y=-4/3x + 22/3
This line goes through both points
Let me know if you need any more help! :)
through: (1, 2), slope = 2
Answer:
y=2x+2
Step-by-step explanation:
Answer: y = 2x
Step-by-step explanation:
y=mx+b
m is the slope. so if the slope is 2 we can fill in 2 for m.
y = 2x + b
now we are going to plug in the point they gave us (1, 2) to find b.
1 is the x coordinate of the point and 2 is the y coordinate. so we put 1 in for x and 2 in for y.
2 = 2(1) + b
2 = 2 + b
b = 0
so our equation is y = 2x + 0, or y = 2x
Which is the BEST estimate of the average rate of change for the function graphed, over the interval 1 sxs 3?

B)

D)

Answer: -3
Step-by-step explanation: just multiply
The best estimate of the average rate of change for the function graphed over the interval 1 ≤ x ≤ 3 is 3.
What is Average Rate of Change of a Function?Average rate of change of a function is defined as the rate at which the value of the function is changing with respect to the change in the input values.
The interval given is 1 ≤ x ≤ 3.
The graph of the function is given below.
It can be clearly seen that,
The y value corresponding to x = 1 is y = f(1) = 2.
So one point on the graph is (1, 2).
The y value corresponding to x = 3 is y = f(3) = 8.
So the other point on the graph is (3, 8).
Average rate of change over 1 ≤ x ≤ 3 = [f(3) - f(1)] / [3 - 1]
= [8 - 2] / [2]
= 6/2
= 3
Hence the best estimate for the average rate of change of function over the interval 1 ≤ x ≤ 3 is 3.

B. 8 x 1/5
C. 2 x 4/5
D. 4 x 2/5
C. 2 x 6/5
Answer:
B, C, and D
Step-by-step explanation:
A) 5 x 1/8 is 5/1 times 1/8 which is 5/8 (Incorrect)
B) 8 x 1/5 is 8/1 times 1/5 (multiply straight across and you get 8/5 (Correct)
C) 2 x 4/5 (again, it's 2/1 just multiply straight across and you are basically only multiplying the two numerators each time. Because 1 times 5 will always be 5) (Correct)
D) Correct because 4 times 2 is 8 which is over 5, hence, 8/5 (Correct)
E) 2 times 6 is 12 over 5 which is 12/5, not 8/5. (Incorrect)

A window washer cleaned 38 windows in 2 hours. At this rate, how many windows did he clean in 7 hours? Record your answer and fill in the bubbles on your answer document. Be sure to use the correct place value
Answer:
133 windows
Step-by-step explanation:
It is given that,
A window washer cleaned 38 windows in 2 hours.
We need to find how many windows did he clean in 7 hours.
2 hours = 38 windows
1 hour = 19 windows
For 7 hours, multiply 19 and 7.
7 hours = 19 × 7 windows
= 133 windows
Hence, in 7 hours he can clean 133 window

Step-by-step explanation:
The system of equations is represented by lines s and t will be,3x + 5y = - 18 and 5x - 9y = 25.
What is the equation?An equation is a statement that two expressions, which include variables and/or numbers, are equal. In essence, equations are questions, and efforts to systematically find solutions to these questions have been the driving forces behind the creation of mathematics.
It is given that,
For S,
x ⇒ -5 2 4
y ⇒ 4 10 22
For T,
x⇒ -4 0 5
y⇒ 14 6 -4

find the values of x and y?
Answer:x=20 y=70
Step-by-step explanation:
Answer:
x=20, y=70
Step-by-step explanation:
∠40°+∠adjacent to it =180°
∠adjacent= 180-40=140°
we see that 2 of the sides of one of the small triangles are congruent so that triangle is isoscel so the base angles are congruent as well
because sum of angles in a triangle has to be 180,
140 +x+x=180 so x=20°
from the right triange we see thhat y +90+20 =180 because sum of angle in a triangle has to be 180 so y=70

PLZ help me with this :(
Part 1: Simplify √250
Part 2: Classify the number above as rational or irrational
Level 3 (Proficient: 85%)
Part 1: Simplify √150x*5
Part 2: Is the follow expression rational or irrational and why? 2√4+7
Level 4 (Distinguished: 100%)
Part 1: Simplify 13√750x*5 y*8
Part 2: Create two unique expressions each involving 1 square root and at least 1 operation (adding, subtracting, multiplying, dividing). Make 1 results in a rational number and the other result in an irrational number. Explain your reasoning for both.
Explanation:
Level 2
Part 1: √250 would be simplified to 5√10, because you need to find two factors that equal 250. 25 multiplied by 10 are two factors that you can utilize. Because 25 is a perfect square, it could be reduced to 5. Because 10 isn't a perfect square, you leave it as a radical.
Part 2: √250 is an irrational number because it's a non-terminating decimal and you cannot convert it into a fraction, so it wouldn't be rational.
Level 3
Part 1: √150x^5 would be simplified to 5x^2√6x. Again, find two factors that equal the product, 150. 25 multiplied by 6 are two factors that are useable. Just like the first question, 25 is a perfect square, so it can be reduced to 5. 6 is not a perfect square, so you would leave as a radical. Now, moving onto x^5. You can factor out x^4, because it's a perfect square. x^4 can become x^2. Move x^2 next to 5 and x would be left in the radical with 6.
Part 2: It's rational because 2√4 is simply just 2 x 2 because √4 is a perfect square. 4+7=11. 11 can be converted into a fraction, so it wouldn't be irrational.
Level 4
Part 1: 13√750x*5 y*8 would be simplified to 65x^2y^4√30x. Find two factors that equal 750, which are 25 and 30. You know the drill, 25 is reduced to 5 and 30 stays as a radical. Multiply 13 and 5 to get 65. Factor out x^4 out of x^5 to get x^2. x^8 is a perfect square that can be reduced to x^4.
Part 2: Two unique expressions are 4√16+3 and 5√8 x 34. √16 is a perfect square, so it can become 4. 4 x 4 is 16 and 16 + 3 = 19. 19 is a rational number. 5√8 is irrational, so right off the bat, you'll know it's an irrational expression.
