8p + 2q = -16
2p - q=2
Answer:
p = -1 q = -4
Step-by-step explanation:
a system of eq and solve for p and q ??? can do :)
Eq. 1) 8p + 2q = - 16
Eq. 2) 2p - q = 2
use Eq .2 and solve for q
2p - 2 = q
plug into Eq.1 with q
8p +2(2p - 2) = - 16
8p +4p -4 = -16
12p = - 12
p = -1
plug -1 into Eq. 1 for p and solve for q
8(-1) + 2q = - 16
-8 + 2q = - 16
2q = -8
q = -4

Answer:
there are two terms which means it is a binomial algebraic expression
Step-by-step explanation:
the first term is -9
and the second term is 5.5

In one year, a school uses 13,270 pieces of white paper, 6,570 fewer pieces of blue paper than white paper, and 2,600 fewer pieces of yellow paper than blue paper. How many pieces of paper does the school use in all?
Answer:
24,070 the school uses in all
Step-by-step explanation:
You subtract 13,270 by 6,570 and you get 6,700 pieces of blue paper. Then, you subtract 6,700 by 2,600 and you get 4,100 pieces of yellow paper. Finally, you add the total of pieces of white, blue, and yellow paper and you get 24,070 for the total.

Graph the rational function y
x2 + 3x
Which quadrant does neither branch of the rational function pass through?
Answer:
Quadrant 4
Step-by-step explanation:
To get this, we need a plot of both equations
A plot of both shows that they both only have values in the 1st, 2nd and 3rd quadrants
They both do not have any values on the 4th quadrant
Use this rule to fill in the table.
Rule: Add 3 to the input to get the output.
Add 3
?
Input
Output
1
0
6
11
Answer:
Input --- Output
1 ------------ 4
6 ------------9
8--------------11
Step-by-step explanation:
Given
Rule:
Output = Input + 3
Required
Complete the table
Represent the input with x and the output, y
So, the rule becomes
[tex]y = x + 3[/tex]
When Input = 1
[tex]x = 1[/tex]
[tex]y = x + 3[/tex]
[tex]y = 1 + 3[/tex]
[tex]y = 4[/tex]
This means:
Output = 4
When Input = 6
[tex]x = 6[/tex]
[tex]y = x + 3[/tex]
[tex]y = 6+3[/tex]
[tex]y = 9[/tex]
This means:
Output = 6
When output = 11
[tex]y = 11[/tex]
[tex]y = x + 3[/tex]
[tex]11 = x + 3[/tex]
[tex]x = 11 -3[/tex]
[tex]x = 8[/tex]
This means
Input = 8
So, the complete table is:
Input --- Output
1 ------------ 4
6 ------------9
8--------------11

The first five terms of a sequence are 7, 10, 13, 16, and 19.
Which of the following functions define this sequence for all integers n ≥ 1?
Answer:
Option B is correct
For , the function for the given sequence is defined as;
Step-by-step explanation:
An arithmetic sequence is a sequence in which the difference between each consecutive term is constant.
An explicit formula for this arithmetic sequence given by;
where a represents first term
Since, the given sequences; 7 , 10 , 13 , 16 and 19
⇒ common difference(d) = 3 and a = 7
Since.
10 -7 = 3
13- 10 = 3 ....
The function which defined this sequence is;
using distributive property:
therefore, the function for the given sequence for all integers is;
