Answer:
<h3>Negative one-half (negative 2) (x + 3) = negative 10 (negative one-half)</h3>
Step-by-step explanation:
Given the expression
- 2 (x + 3) = - 10
The first step in solving the expression is to multiply both sides by -1/2 as shown;
-1/2(-2)(x+3) = -1/2(-10)
(x +3) = 1/2(10)
x + 3 = 5
x = 5-3
x = 2
Hence the correct option is Negative one-half (negative 2) (x + 3) = negative 10 (negative one-half)
In this exercise we have assumption:
x-4>0
x>4
from this we know domain : x∈(4,+infinity)
range y∈R
Answer:
45
Step-by-step explanation:
Answer:
Tappan is $1400
Hill is $1420
Step-by-step explanation:
Particulars Tappan Hill
Tons purchased 4500 7500
Tons discarded 135 375
% plastic discarded 3% 5%
% plastic accepted for 97% 95%
Quoted price 1358 1349
% accepted for 97% 95%
Effective cost per ton
= Quoted price / % accepted for
$ 1400 $1420
Effective cost per ton
Tappan Hill
$1400 $1420
if x is a regular cip of coffee and y is a large cup of coffee. the first part of the equation being the number of the cups of coffee and the second part expressing the price. using the method of substitution we solve for x in the first equation
x= 5-y
and then we solve for y
then we substitute the value found in the easiest equation which would be the first one and we solve for x
x + 2 = 5
x + 2 - 2 = 5 - 2
x = 3
so its 3 regular cups and 2 large
