The total cost will be $56 because 3 x 8 = 24 so then you multiply 7 x 8 = 56.
We have two points, (3,0) and (0,-3). So we can find the slope of the line:
m=(y2-y1)/(x2-x1)
m=(-3-0)/(0-3)
m=-3/-3
m=1 so far for the line y=mx+b we have:
y=x+b, b is the y intercept which we were told is -3 so
y=x-3
The above is called the slope-intercept form of a line, y=mx+b, the standard form of a line is ax+by=c, so we need to get both variables on one side of the equation..
y=x-3 subtract x from both sides
-x+y=-3
While the above may be acceptable to some, technically the coefficient of x should be expressed as a positive value, so we should divide the above "solution" by -1 to get:
x-y=3
Answer:
−1.13348172≤x≤1.13348172
Step-by-step explanation:
For this problem
Add −5x2 to both sides of the inequality.
−x16 + 1 + 5x2≥0
Convert inequality to an equation.
−x16 + 1 + 5x2 = 0
Factor −x16 + 1 + 5x2
Set the factor equal to 00.
x16−5x2−1 = 0
x≈ − 1.13348172,1.13348172
so,
x≤ − 1,13348172
−1.13348172≤x≤1.13348172
x≥1.13348172
−1.13348172≤x≤1.13348172
Answer:
First find line DE using Pythagoras theorem
That's
DE² = 7² + 24²
DE = √ 49 + 576
DE = 25
The correct trigonometric ratio for triangle DEF is
Cos(E) = 24/25
Hope this helps
Answer:
Step-by-step explanation:
Important: Please use " ^ " to indicate exponentiation: 5(3x - 4)^2 is correct.
This is "five times the square of the difference between 3x and 4."
