Answer:
x=15
Step-by-step explanation:
the angle 7x+12 and 63 are on opposite sides of complimentary, meaning they add to 180.
180-63 = 117
117-12 = 105
105/7 = 15
Just to avoid some confusion: <u>the first picture is a graph of function A, and the second picture is a graph of function B. </u>
Answer:
D. Function A is non-linear and Function B is linear.
Step-by-step explanation:
A good way to find out if a function is linear is by graphing it. If you graph it and it is a straight line, then it is linear.
So, let's graph the given points from the table of Function A and see if it forms a straight line. When you connect the dots, it's not straight, so Function A is non-linear.
Now let's look at function B. We can graph that too with the given information from the equation - the slope is -1 and the y-intercept is 5. (If you are a bit confused on how to graph it, don't hesitate to ask!) It does form a straight line, so Function B is linear.

We have the following:
1.
let x a tulips
let y daffodils
therefore:

solving:

for x:

Therefore, the answer is 5 tulips and 10 daffodils
2.
let x a 30% silver
let y a 55% silver

solving:

for x:

Therefore, the answer is 480 pounds of 30% silver and 320 pounds of 55% silver
