Answer:
2
Step-by-step explanation:
1+1=2
Think of it like this 1 donut plus another donut . Now you have two donuts
1 mile = about 1 1/3 km because 8/6 = 1 1/3
so 28 times 1 1/3 = 37 1/3 (first answer)
42 / 6 = 7
7 miles are in 42 km (2nd answer)
You just substitute the value of x in the given equation:
f(x) = 2x^2 - 5
f(-4) = 2 (-4)^2 -5 = 27
f(x) : a name given to the equation
f(-4): refer to the equation when the value of the independent variable x has the value between the brackets.
so, you just use the x's from the table and plug them into the equation to find the y.
y=(1)+9
y=10
y=(2)+9
y=11
y=(3)+9
y=12
y=(4)+9
y=13
i hope this helps :)
I agree with the answer above me but i don’t rly know history so good luck
