I think one is c And 2 I think is a I just use the desmos graphing calculator at desmos.com
Answer:
$0.02
Step-by-step explanation:
Brand a
1.28 ÷ 8 = 0.16 per ounce
Brand b
1.68 ÷ 12 = 0.14 per ounce
0.16 - 0.14 = 0.02
Answer:
Without looking, he guesses that half of the marbles in the b… ... of the marbles in the bag are green. He randomly selected 1 marble from the bag, recorded the color, and returned the marble to the bag. After 15 trials, Mark has drawn 10 green marbles and 5 white marbles.
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
Vertex form is y=a(x-h)^2+k where (h,k) is vertex
So replace h with -3 and k with 2
y=a(x--3)^2+2
y=a(x+3)^2+2
So the only choice it could be is D
+ y = -1 ⇒ y = - 1
To graph this line, plot a point at the y-intercept (0, -1), than plot the next point using the rise over run from the slope by counting up 1 and to the right 3 of the y-intercept. This gives you a second point of (3. 0). Draw a line through those two coordinates.
Answer: Plot (0, -1) and (3, 0) and draw a line through them.

y = 4 + ⇒ y = + 4
Same as above. Plot the y-intercept (0, 4) and then use rise over run from the slope to plot (3, 5).
Answer: Plot (0, 4) and (3, 5) and draw a line through them.

You should end up with two PARALLEL lines. Since the lines never intersect, there are no solutions to this system of equations.
Answer: No Solution
