Answer:
The relation is not a function.
Step-by-step explanation:
The relation isn't a fuction because one input value of X cannot have 2 output values. ( 5 is -8 and 5)
The perimeter of the rectangle that Tamara will create is 26 inches. Given that the length is greater than width, the width may be expressed as l - 3. The perimeter of the rectangle is solved by,
P = 2l + 2w
Thus, the equation is,
2l + 2(l - 2) = 26
Answer:
(-6,5]
Step-by-step explanation:
Domain includes all of the x-values a function contains. In this case, it goes from -6 to 5. The open dot on the left indicates that this number is not included in the answer, and in interval notation you would use a parentheses. The filled in dot on the right coordinate indicates that this number is included, so you would use a bracket.
Answer:
7x + 6y = 24
Step-by-step explanation:
y = -7/6x - 3
Standard form: Ax + By = C
7x + 6y = -18
Since it's parallel, Ax and By have to be the same
The only choice is
7x + 6y = 24
Answer:
x=10
Step-by-step explanation:
Let's solve your equation step-by-step.
40−x=3x
Step 1: Simplify both sides of the equation.
40−x=3x
40+−x=3x
−x+40=3x
Step 2: Subtract 3x from both sides.
−x+40−3x=3x−3x
−4x+40=0
Step 3: Subtract 40 from both sides.
−4x+40−40=0−40
−4x=−40
Step 4: Divide both sides by -4.
−4x
−4
=
−40
−4
x=10
