Answer:
D. Multiply the second equation by 3. The solution is x = 12, y = 10.
Step-by-step explanation:
First, look at the y variable of the first equation. It is 3y.
To solve by elimination, the variables have to add together to 0.
So, -3y needs to be added to -3y to eliminate the y variable.
The second equation has the y variable of -y, so it has to be multiplied by 3.
So, answer choice D is the correct answer.
Answer:
y=3x+3
Step-by-step explanation:
Lets say that week weight in ounces is 'y' variable, and the week number is 'x' variable
Lets also remember the equation for a line, y=mx+b, where m is the slope and b is an offset (the value the function has when x=0), the slope is obtained from equation (y2-y1) / (x2-x1)
The selected points will be (1,6) as Point 2 and (0,3) as Point 1. We have m=3
And from the point 1 we can also obtain the value for b.
So y=3x+3
Answer: b=27
Step-by-step explanation: Add 119+34 and you get 153. Subtract 153 from 180 and you get 27. Hope this helps.
Answer:
ab • (11a + b + 1) If its not im really sorry
Step-by-step explanation:
STEP one
(((((3•(a2))•b)+5ab)-4ab)+(a•(b2)))+(23a2•b)
STEP Two
((((3a2 • b) + 5ab) - 4ab) + ab2) + 23a2b
STEP 3
STEP 4
Pulling out like terms
4.1 Pull out like factors :
11a2b + ab2 + ab = ab • (11a + b + 1)
I’m not sure about the second half but since it’s a triangle all of the angles add up to 180° so you can find the third angle by adding 61 and 90 then subtracting that from 180 to get the third angle
