Solve the system of equations y = 2x + 3 and 4x - 2y = -6 using a graphical method.
A) (-3/2 , 0)
B) (3/2 , 6)
C) (2 , 7)
D) infinite solutions
Answers
To graph a linear equation, first you plot the y-intercept, then move the point depending on your slope.
First, you need to solve 4x - 2y = -6. So you subtract 4x on both sides, then divide each side by -2. This gives you y = 2x + 3.
Y = 2x + 3 is point (1, 5) on the graph. And since the graphs of the equations are the same, there are infinite solutions.

The question is in the picture
Answers
Therefore, we need to find the slope (“m”) of the line (change in y/change in x), which is rise/run. We also need to find the y-intercept (“b.”)
1.) (0, -3) (1, -1)
We took two points from the line to find the slope. We will use the 2 coordinate pairs to find the slope.
2.) m=(y2-y1)/(x2-x1)
This is the slope “m” formula.
3.) m=( -1+3)/(1-0)
Input the coordinate values into the formula. The +3 you see is due to -(-3)=+3.
4.) m=2/1
We simplified the above formula.
5.) m=2
By division.
We now have the slope or “m.” M=2. Therefore, the equation rises 2 units and runs 1 unit.
Now, finding the y-intercept:
The y-intercept or “b” is where the line intersects the y-axis. It is the starting point of a linear equation.
To find the y-intercept, we need to figure out what the output is when the input is 0. We can see on the table in the picture that with an input of 0, the output is -3.
Therefore, b=-3. This is because an input of 0 means that there is no movement on the x-axis, so we can determine where the where the linear intercepts the y-axis.
Therefore, the equation is y=2x-3, where m=2 and b=-3.
That’s the answer: y=2x-3

Slope intercept form
Answers
Answer:
y=-3x+1
Step-by-step explanation:
1) the slope-interception form is: y=slope*x+intercept;
2) if A(0;1) and B(2;-5) then it is possible to make up the equation of the required line:
[tex]\frac{x-X_A}{X_B-X_A} =\frac{y-Y_A}{Y_B-Y_A}; \ => \ \frac{x}{2}=\frac{y-1}{-6};[/tex]
3) the equation in the item 2 can be written in slope-interception form:
x=(y-1)/(-3); ⇔ y-1= -3x; ⇔ y= -3x+1.
P.S. note, the suggested way of solution is not the shortest one.

Answer:
Step-by-step explanation:
A function is one-to-one if it passes the horizontal line test. This is the case if a horizontal line intersects the graph in only one place.
The graph of f(x) = x^2 - 5 is that of a parabola that opens upward. There are several possibilities here:
1. The horizontal line intersects the parabolic graph twice on the interval (-infinity,+infinity). Therefore this function is not one-to-one on this interval
(-infinity,+infinity).
2. If we define the domain as [0,+infinity), a horizontal line will intersect this parabolic graph only once. Therefore this function is one-to-one on [0,+infinity).

Step-by-step explanation:
Using the distributive property:
[tex]-23x(x+3)[/tex]
You will multiply both the x and the 3 inside the parantheses by the -23x outside.
[tex]-23x[/tex] · [tex]x = -23x^{2}[/tex]
Then:
[tex]-23x[/tex] · [tex]3 = -69x[/tex]
If you combine both you will recieve:

Step-by-step explanation:
Reason for this is 9m is the same as 9 multiplied by m, or the product of 9 and m. You always do multiplication before subtracting or adding, therefore you are subtracting 3 FROM the product of 9 and m

Step-by-step explanation:
Step 1: Define
1 2/3 ≥ r - 7/12
Step 2: Solve for r
Rewrite: 5/3 ≥ r - 7/12
Isolate r: 9/4 ≥ r
Rewrite: r ≤ 9/4
Reduce: r ≤ 2 1/4
Here we see that any number r less than or equal to 2 1/4 will work as a solution to the inequality.

A washing machine is on clearance for 30% off. If the sale price of the washing machine is $395.49, what was the original price? Round to the nearest cent if necessary. Justify your solution.
Answers
Answer:
Discount = Original Price x Discount %/100
Discount = 395.49 × 30/100
Discount = 395.49 x 0.3
You save = £118.65
Final Price = Original Price - Discount
Final Price = 395.49 - 118.647
Final Price = £276.84. (ANSWER)
original price of washing machine is $564.99 if the sale price of the washing machine is $395.49 with 30% off.
What is Percentage?Percentage is defined as a given part or amount in every hundred
Based on the given conditions, formulate:
x×(1-30%)=395.49
Apply multiplicative distribution
x-0.3x=395.49
Combine the like terms
0.7x=395.49
x=395.49/0.7
Convert decimal to fractions
x=(39549/100)/(7/10)
x=39549/(10×7)
x=39549/70
x=564.99
Hence original price of washing machine is $564.99

one number is 15 more than a second number.The sum of the number 115. What are the numbers?
Answers
The second number is 50
X= first number
Y= second number
X+Y= 115 > or 2y+15= 115 > subtract 15 from both side
2y= 100> divide by 2 on each side> y=50
There you have solved for y, now solve x
X= 50+15 > which is 65
So therefore, the first number is 65 and the second is 50.

Value of f(-10) is 1100
Step-by-step explanation:
Given that f(x) = x² - x³
Here we need to find f(-10).
f(-10) = (-10)² - (-10)³
f(-10) = 100 - (-1000)
f(-10) = 100 + 1000
f(-10) = 1100
Value of f(-10) is 1100

Step-by-step explanation:
∠JTS = ∠SRT + ∠TSR {exterior angles equals sum of opposite interiror angles}
27x - 4 = 18x + 2 + 30
27x - 4 = 18x + 32
Add 4 to both sides
27x = 18x + 32 + 4
27x = 18x + 36
Subtract 18x from both sides
27x - 18x = 36
9x = 36
Divide both sides by 9
x = 36/9
x = 4
∠JTS = 27x - 4
= 27*4 - 4
= 108 - 4
= 104
