x≤ 7 is the answer I could find hope it helps
Answer:
y = 9.8995
Step-by-step explanation:
This question requires the use of basic trigonometry.
In this problem, we know one of the sides and two of the angles.
Since one of the angles is 45 degrees and the sum of all internal angles of a triangle is 180 degrees, the other angle can only be 45 degrees, making this an isosceles triangle - that is, the length of the other leg, x, is also 7.
You could use the soh cah toa mnemonic to figure it out, but here just using the a^2 + b^2 = c^2 should be sufficient since we know both legs of the triangle.
7^2 + 7^2 = 98, and the square root of 98 gives you about 9.8995, which sounds about right for this situation.
Hope this helped!
(x - 2)^2 will always be positive and will have a minimum value of 0
so f(x) will have minimum of 2
Range is [2,∞)
Answer: 2 4/9
The decimal equivalent is 2.44
Step-by-step explanation:
It may help to convert the fractions to decimals. Divide the numerator by the denominator.
2 3/8 is 2.375
2 1/8 is 2.125 etc.
Remember that absolute value is considered positive. Then put the numbers in order.

Answer:
Step-by-step explanation:
Where x represents the previous year's salary, its amount this year is said to be ...
x + 2000
The equation is trying to reflect the fact that 7% of that is $3,290. The missing number is 2000:
0.07(x +2000) = 3290
__
Solving for x, we find ...
x = (3290/0.07) -2000 = 45000
Sandra's salary the previous year was $45,000.
