It's B cause it's open upwards.
Answer:
k = 2
Step-by-step explanation:
(-2,1) = (x,y) So you substitute -2 and 1 for x and y
1 = -(-2) - 1 1 = 1/2 × -2 + k
1/2 × -2 = -1 -1 + 2 = 1
k = 2 1 = 1/2 × -2 + 2
I hope this helps
So let's put it this way-
N% x 60 = 42
You want to isolate the variable
42/60 = N%
42/60 is .7 which is 70%
Hope this helps :)
The solution to the inequalities x + 8y ≤ 50, x ≤ 30, y > 2 is the darker region shown on the graph.
<h3>What is an equation?</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
Let x represent the number of individual songs and y represent the number of albums, hence:
x + 8y ≤ 50 (1)
x ≤ 30 (2)
y > 2 (3)
The solution to the inequalities x + 8y ≤ 50, x ≤ 30, y > 2 is the darker region shown on the graph.

Answer:
0.74
Step-by-step explanation:
We can isolate x, getting 9.2x - 1.9x = -1 + 6.4
We can then simplify, getting 7.3x = 5.4, which we can solve by dividing both sides by 7.3:
x = 5.4 / 7.3 = 0.74
