We can't use P = 2L + 2W because the sides have different lengths.
P = a + b + c + d
a = x
b = 2x
c = 2x - 2
d = x + 5
P = x + 2x + (2x - 2) + (x + 5)
P = <u>x + 2x + 2x</u> - 2 <u>+ x</u> + 5
P = 6x + 3
if x = 4:
P = 6 · 4 + 3
P = 24 + 3
P = 27
11/2 * -11/4 = (11*-11) / 2*4 = -121 / 8
= -15 1/8 answer
-2 1/4 * -4 1/2
= -9/4 * -9/2
= 81/8
= 10 1/8 answer
If a large pizza cost 15 dollars and the medium pizza is 9 dollars.Since the pizza parlor sold only 5 large pizzas, then… 15 x 5 = 75Deduct this from the total amount of pizza sold…$291 - $75 = $216So, the pizza parlor sold a total of $216 for the medium pizzas. Divide this to the amount of one medium pizza. $216 / 9 = 24.So the pizza parlor sold a total of 24 medium pizzas.
Answer:
Option b is correct.
Linear function ;
y =2x
Step-by-step explanation:
The formula y=f(x)=mx +c ......[1] is said to be a linear function. That means the graph of this function will be a straight line on the (x, y) plane, where m represents slope and b is the y-intercepts.
Consider any points from the table;
(1, 2) and (2, 4)
substitute these point in [1] we get;
for (1, 2)
⇒x = 1 and f(x) = 2 we have
2 = m + c
or
c = 2- m ......[1]
for (2, 4) we have;
4 = 2m + c .....[2]
Now, substitute equation [1] into [2] we get;
4 = 2m + 2 -m
Combine like terms;
4 = m + 2
Subtract 2 from both sides we get;
4 -2 = m +2 -2
Simplify:
2 = m or
m = 2
Substitute the value of m = 2 in [1] to solve for c;
c = 2 -2 = 0
c =0
⇒ y = 2x +0
y = 2x
therefore, the data in the table represents the Linear function and a possible formula for the linear function is; y = 2x
