Which answer best describes the system of equations shown in the graph?
Inconsistent
Consistent and independent
Consistent and dependent
Answer:
we conclude that the given system of equations is consistent and independent.
Hence, option B is true.
Step-by-step explanation:
From the figure it is clear that the two lines intersect at one point.
In other words, there is only one point of intersection of the given system of equations.
It means the system of equations contains exactly one solution.
We know that If a consistent system contains exactly one solution, it is termed as an independent.
Therefore, we conclude that the given system of equations is consistent and independent.
Hence, option B is true.

Which number line represents the solution set for the inequality - 2x2 4? -10 -8 6 -4 -20 2 4 6 8 10 -10 -8 6 + -2 0 2 -4 6 + -10 -8 6 -4 -2 0 2 68 10 -10 -8 -6 -4 -2 0 6 810
Answer:
Option (2)
Step-by-step explanation:
Given inequality is,
[tex]-\frac{1}{2}x\geq 4[/tex]
⇒ [tex]\frac{1}{2}x\leq -4[/tex]
⇒ x ≤ -8
When we plot this inequality on a number line,
An arrow starting with a solid point from x = -8 and arrow directing towards negative numbers will represent the given inequality.
Option (2) will be the answer.
Answer:
[tex] - \frac{1}{2} x \geqslant 4 \\ - x \geqslant 2 \times 4 \\ - x \geqslant 8 \\ \boxed{\ x \leqslant - 8}[/tex]
x→{-∞,-8]
Number line :---
Arrow which represents solid sphere directed from (-8) moving towards left (-∞) will be the answer
2nd one is the right answer.For each sequence find the first four terms and the tenth term 3n-4
Answer:
= 1, 2, 5, 8 and 26
Step-by-step explanation:
To find the first 4 terms, substitute n = 1, 2, 3, 4 into the formula
a₁ = 3(1) - 4 = 3 - 4 = - 1
a₂ = 3(2) - 4 = 6 - 4 = 2
a₃ = 3(3) - 4 = 9 - 4 = 5
a₄ = 3(4) - 4 = 12 - 4 = 8
The first 4 terms are
- 1, 2, 5, 8
Substitute n = 10
a₁₀ = 3(10) - 4 = 30 - 4 = 26
Answer:
Below.
Step-by-step explanation:
We get the first 4 terms by plugging in n = 1 2 3 and 4:
3(1) - 4 = -1 , 3(2) - 4 = 2 ...
First 4 terms are
-1, 2, 5, 8
10th term = 3(10) -4 = 26.
When creating equivalent fractions (creating common denominators) you only need to change the denominators.

What is the slope and y-intercept of the equation 8x +
+ 2y = 18
Show work
Please
Answer:
SLOPE = - 4
y-intercept = 9
Step-by-step explanation:
Slope = - 8/2 = - 4
Y-INTERCEPT = 18/2 = 9
Consider the line 2x + 4y=5.
What is the slope of a line parallel to this line?
What is the slope of a line perpendicular to this line?
slope of the line is given by
2x+4y=5
4y=-2x+5
y=(-2/4)x+5/4
y=(-1/2)x+5/4
from, y=mx+c
m=-1/2
slope of a line parallel to this line
from, m1=m2
slope, m=-1/2
slope of a line perpendicular to this line
from, m1m2=-1
(-1/2)m2=-1
m2=2
slope, m=2

PLEASE HELP ME HURRY I REALLY NEED THIS!!!! Graph the equation.
y = 2x + 4
Answer:
Step-by-step explanation:
Answer:
The slope is 2/1. The y-intercept is 4.
Step-by-step explanation:
First graph 4 on the y-axis (0,4). From there your going to up by 2, and right 1. Keep going until you can’t graph no more. Now go back to your point (0,4) go backwards now so Down 2, left 1. Graph until you can’t anymore. And your done! Make sure to add arrows and write down the equation on the line.
If a point is translated down 6 units, what are the new coordinates expressed as an algebraic representation?
Answer:
(x , y - 6)
Step-by-step explanation:
The y-axis deals with up and down motions. To shift a point downwards six units, subtract 6 from the value do the y-coordinate.

5.Footlocker buys Air Jordans for $30 a pair. They mark it up 75%. How much is the mark-up on a pair of Air Jordans
If you buy a pair of Air Jordans as mentioned in question #5, how much would you end up paying? (Hint: original amount + mark-up amount)
Answer:
$52.50
Step-by-step explanation:
What you do is you move the decimal two times to the left from 75%.
0.75*?=?
Take the orginal price and multiply ($30) by 0.75.
0.75*30= $22.50
Take 22.50 and add that to your original amount.
$22.50+$30= $52.50 or $52.5

A new car cost $18,000.00. It is expected to depreciate at an average rate of 15% per year. Find the value of the car in 5 years. Show work.
Answer: $1.37
Step-by-step explanation:
[tex]c (t) = 18,000 (0.15)^{t}[/tex]
t = amount of years
[tex]c (5) = 18,000 (0.15)^{5}\\c (5) = 18,000 * 0.0000759375\\c (5) = 1.366875\\[/tex]
1.366875 ≈ 1.37
c (5) = 1.37
In 5 years, the value of the car should be approximately $1.37
