Linear means the highest exponent on the placholder is 1
it is also just a straight line

y=|x| is like y=(√x)², it is 2 straight lines

B. y=x², exponent is 2 so no

C. y=-3x³, exponent is 3, so no

D. y=1/4x, yep


D is the answer

2) 16 + -7<br><br> Step by step please
gregori [183]

Answer:

9

Step-by-step explanation:

The rules that you need to know for this question are:

- & - = +

+ & - = -

+ & + = +

So for this question we have 16 + -7 so we need to use the + & - rule. Therefore a plus and a minus make a minus so we do 16-7 which is 9

the town of lantana needs 14,000 for a new playground. Lantana elementary school raised 5,358, Lantana middle school raised 2,83
Alecsey [184]
Assuming the question is "how much more money needs to be raised..."

Add the contributions:

5,358 + 2,834 + 4,132 = 12,324 < this is the current total amount raised. subtract this from the goal, 14,000 to find out much more money is needed for the playground.

14,000 - 12,324 = 1,676

Answer: $1,676  is still needed in order to create the playground.

Pls help me!!!!!!!!!!!!!!!!!!!!!!!!
SIZIF [17.4K]

Answer:

x = 3y + 1

Step-by-step explanation:

You need to find the relationship between x and y before finding the y-intercept.

0-(-1) = 1

1-0 = 1

2-1 = 1

1-(-2) = 3

4-1 = 3

7-4 = 3

As x increases by 1, y increases by 3.

At x = 0, y is already 1. Thus:

x = 3y + 1

What is the value of f(7)
kkurt [141]
F(7) means f(x) when x = 7. The x is replaced with 7.

So we'll replace every x with 7 to go from x = 7 to 3-x = 3-7 = -4

Put another way
f(x) = 3-x
f(7) = 3-7
f(7) = -4

Answer: -4
