Answer:
13
Step-by-step explanation:
The product of two negative numbers is positive. The absolute value of a number is its magnitude written with a positive sign.
6 -2(-1) +|-5|
= 6 + 2 + 5
= 13
Answer:
-5x^2 - 25x + 18
Step-by-step explanation:
-3x ( x + 8 ) + x + 2 ( 9 - x - x^2 ) ( original equation )
-3x^2 - 24x + x + 18 - 2x - 2x^2 ( distribute )
-3x^2 - 2x^2 - 24x + x - 2x + 18 ( order them based on the variables . )
( -3x^2 - 2x^2 ) (- 24x + x - 2x ) ( + 18 ) ( just separated them not a part of solving !! )
-5x^2 - 25x + 18 ( solved , and the answer :) )
Hope its helps !!!
X = 8.5 because 8.5 x 2 = 17 and 17 + 1 = 18
Answer:
5
Explanation:
Data Set : {11, 13, 9, 4, 6, 5, 8, 10}
Arrange ascendingly: {4, 5, 6, 8, 9, 10, 11, 13}
Quartiles:
Interquartile Range: Q3 - Q1 = 10.5 - 5.5 = 5
Answer:
(x, y) = (-15, -14)
Step-by-step explanation:
y = x+1
y = 2/3x - 4
Next, we will substitute the value of y (first equation) into the second equation.
x+1 = 2/3x - 4
1/3x + 1 = -4
1/3x = -5
x = -15
So, y = -14
