Answer:
False
Step-by-step explanation:
The left side 2 does not equal to the right side 18
, which means that the given statement is false.
Answer:
Step-by-step explanation:
point p is on line r
line r passes through point P
line r contains point P
Function, put input (domain) and get output (range)
the answer is a function
Answer:
x= -1
y = 9
Step-by-step explanation:
to solve this system of equation
let
x - 2y = -19.....................................equation 1
-3x + 5y = 48 .................................. equation2
from equation 1
x - 2y = -19.....................................equation 1
x = -19 + 2y................................... equation 3
substitute the value of x into equation 2
-3x + 5y = 48 .................................. equation2
-3(-19 + 2y) + 5y = 48
57 - 6y + 5y = 48
combine the like terms
-6y + 5y = 48 -57
-y = - 9
divide both side by -
y = 9
put y= 9 into equation 3
x = -19 + 2y................................... equation 3
x = -19 + 2(9)
x = -19 + 18
x = -1
therefore the value of x and y is -1 and 9 respectively
L= length= 2w+4
w= width
P= perimeter= 7w-3
SOLVE FOR WIDTH
Perimeter of a Rectangle Formula
P= 2(l + w)
7w - 3= 2((2w + 4) + w)
combine like terms in parentheses
7w - 3= 2(3w + 4)
multiply 2 by parentheses
7w - 3= (2*3w) + (2*4)
multiply in parentheses
7w - 3= 6w + 8
add 3 to both sides
7w= 6w + 11
subtract 6w from both sides
w= 11 width
LENGTH
l= 2w + 4= 2(11) + 4= 22 + 4= 26
PERIMETER
P= 7w-3= 7(11) - 3= 77 - 3= 74
CHECK
74= 2(26 + 11)
74= 2(37)
74= 74
ANSWER: The length is 26, the width is 11 and the perimeter is 74.
Hope this helps! :)
