Answer:
f(-3)= -3
Step-by-step explanation:
We are given the function:
f(x) = 2x+3
and asked to find f(-3). Essentially, we want to find f(x) when x is equal to -3.
Therefore, we can substitute -3 for each x in the function.
f(x)= 2x+3 at x= -3
f(-3)= 2(-3) +3
Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition and Subtraction
Multiply 2 and -3.
f(-3) = (2*-3) +3
f(-3)= (-6)+3
Add -6 and 3.
f(-3)= (-6+3)
f(-3)= -3
If f(x)= 2x+3, then<em> f(-3)= -3</em>
7x-2+5=37x+-3=3
should be your answer unless i've done it incorrectly, in which case you should still check your work before using my answer.
Answer:
Dimensions : L = 12 inches, Width = 2 inches
Step-by-step explanation:
Let width be w
Let length be w + 10
Area = length x width
24 = w x (w + 10)
Since width is a side of a rectangle , it cannot be negative. so w = 2 inches .
Therefore , length = w + 10 = 12inches
Next three terms after 27 are <u>36, 45 and 54.</u>
