Ok so
sale is 15% off
and add 6% tax
100-15=85
100+6=106
therefor
1250 with 15% discount plus 6% tax means
1250 times 85% times 106% =
1250 times 0.85 times 1.06=1126.25
final cost=$1126.25
Answer:
a. f(1) = -4
b. One value of x for which f(x) = -1 : 2 (or -2)
Step-by-step explanation:
a. To find f(1), we would have to find what the value of the function would be when x = 1. By using the given graph, we can find the f(1) by finding what the y-value is when x = 1. Looking at the graph, we can see that when x = 1, y = -4. Thus, f(1) = - 4.
b. Now we are also asked to find one value of x for which f(x) = -1. In other words, what values of x would make the value of the function equal to -1? We can find values of x for which f(x) = -1 by using the graph and seeing for which x-values would the y-value be -1. We can see that y = -1 at x = -2 and x = 2. So the values of x at which f(x) = -1 are -2 and 2. You can choose either one of these values.
I hope you find my answer and explanation to be helpful. Happy studying.
Answer:
x=5
Step-by-step explanation:
3x-4=6+x
You want to get x by itself. So, you would subtract x from the right side, and subtract it from 3x. That gives you this:
2x-4=6
Now you would add 4 to cancel out on the left side, then add it to the 6. This gives you:
2x=10
Now divide 2 from both sides and that gives you what x equals.
x=5
Answer:
The distance of the last ramp is <u>10</u> feet.
Step-by-step explanation:
From the options and the question, I assume that the height of the ramp is 6 feet. Pythagorean theorem states:
a² + b² = c²
where <em>c </em>is the hypotenuse, and <em>a</em> and <em>b</em> are the legs of the triangle. In this case:
6² + 8² = x²
√100 = x
10 ft = x
It consisting of three terms so it's trinomial
