The correct answer should be 4. 2 times 0.3 is 0.6. 3.4 plus 0.6 equals 4. ;)
Answer:
B. 7y - 15
Step-by-step explanation:
Simplifying
10y + -3(y + 5) = 0
Reorder the terms:
10y + -3(5 + y) = 0
10y + (5 * -3 + y * -3) = 0
10y + (-15 + -3y) = 0
Reorder the terms:
-15 + 10y + -3y = 0
Combine like terms: 10y + -3y = 7y
-15 + 7y = 0
Solving
-15 + 7y = 0
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Add '15' to each side of the equation.
-15 + 15 + 7y = 0 + 15
Combine like terms: -15 + 15 = 0
0 + 7y = 0 + 15
7y = 0 + 15
Combine like terms: 0 + 15 = 15
7y = 15
Divide each side by '7'.
y = 2.142857143
Simplifying
y = 2.142857143
Answer: the mean is -1.1
Step-by-step explanation: add up each number and divide the sum by 5 since there are 5 numbers in the table. (-32.6 + 24.7 + -8.3 + 19.1 + -8.4 = -5.5/5 = -1.1
-13i+5 8-3=5 and -15i+2i=13i so -13i+5 would be the answer..
Answer: you will win for any distances greater than 190ft.
To find the rate, you’ll first need to find the slope between two points
Slope formula: m=y^2 - y^1 / x^2 - x^1
Plug the equation in: 76-38/4-2
Substitute. subtract, & divide and you get m=19
Then you have to do slop intercept form:
Formula: y-y1= m(x-x1)
Plug in the equation:
Y-38=19(x-2) substitute
Y-38=19-38 distribute
Y= 19x
Then you graph it (I attached a graph pic)
On the graph there’s two lines that intersect at (10,190). For x less than 10, you will run farther than your friends = you will win.
