Answer:
The y-value is -20
Step-by-step explanation:
So let's solve this by Elimination method;
-2(4x + 5y = -12)
4(2x + 3y = -16)
Let's Distribute;
-8x - 10y = 24
8x + 12y = -64
So x cancels out because -8 + 8 = 0
-10y + 12y = 2y
24 - 64 = -40
2y = -40
Divide both sides by 2;
y = -20
Now lets plug in y to find the value of x;
4x + 5(-20) = -12
4x - 100 = -12
Add 100 to both sides;
4x = 88
Divide both sides by 4;
x = 22
Group 1:-
5 cookies
3 people
5/3
Group 2:
8 cookies
6 people
8/6
Group 1 each person gets 5/3 and in group 2 each person gets 8/6.
Which is more?
5/3
5 ÷ 3 ≈ 1.6
8/6
8 ÷ 6 ≈ 1.3
Is 1.3 more or 1.6?
1.6 is more.
5/3 (group 1) receive more.
The value of y = 40.
5x = 40
x = 8
180 = 40 + 40 + (2y + 20)
40 = y
First question, answer is A, the starting point in the graph shows it’s (0,150) while the slope is 30, look at the labeled axis.
second question, i have to do work for it, i can answer it later. remind me. but in order to find the slope, the formula is delta y over delta x. then to find the y intercept, do what’s called “collect the evidence”. this is when you fill out all needed info, it will look like this- y= x= m= b= ??
idk ab the third question, they would all make the function fine?? idk i’m confused, it doesn’t make sense
fourth question, the answer would be B
