2x+7+12y+1=180 and
2x+7=3x-7
x+6y=86 and
x=14
so x+6y=86 is 14+6y=86
6y=72
y=12
answer: x=14 and y=12
Answer:
Step-by-step explanation:
Subtract first from second
= 2x^2 + 3x + 5
Answer:
y = -1/2x + b meaning f(x) = -1/2x + b
Step-by-step explanation:
Use two points on the graph that you can find the value of or use Slope = raise/run
let use points (2,0) and (0, 1)
slope = (change in the y-value)/(change in the x-value.
slope = (1 - 0)/(0 - 2)
slope = 1/-2 or -1/2
Or starting at point (2, 0) the run(x movement) = -2 and the raise is 1.
slope = raise/run
slope = 1/-2 or -1/2
Using one point (2,0) and the slope of -1/2, substitute into the slope intersect form, y = mx + b, and solve for "b" .
y= mx + b
0 = -1/2(2) + b
0 = -1 + b
1 = b
Now write your equation: y = mx +b where m = -1/2 and b = 1
y = -1/2x +b

1. the pitcher is full because it can hold 1 liter, which is 1000ml and 500+400=900 so there would be 100ml before it would overflow.
2. Grant uses 3000ml of ginger, since 3g=3000ml.

6. 4L = 4000ml
9L = 9000ml
7. 6g = 6000mg
11g = 11000mg
8. 5kg = 5000g
17kg = 17000g
hope that helps!
