Answer:
x = ±sqrt(2)
Step-by-step explanation:
It is not a function if the same input goes to 2 different outputs
x^2 +3 =5 would cause the same input to go to 2 different outputs
Subtract 3 from each side
x^2 +3-3 =5-3
x^2 = 2
Take the square root of each side
sqrt(x^2) = ±sqrt(2)
x = ±sqrt(2)
Answer:
x = sqrt(2), -sqrt(2)
Step-by-step explanation:
For a function, there cannot be multiple outputs for the same input, therefore x²+3 should not be 5
x² + 3 = 5
x² = 2
x = +/- sqrt(2)

(25 points!!!!) draw the graph of the area bounded by these inequalities
Step-by-step explanation:
To draw the graph, follow these steps:
Graph the lines using points from the equations. (the blue line shown should be dotted, unfortunately I cannot do that in the program I used)Determine which direction the inequalities are correct. Find the boundary given.The three inequalities given form a triangle.
The first equation, y ≤ 2x + 5, has a y-intercept at (0, 5) and a point at (-2, 1).
The second equation, y < -3x + 10, has points at (3, 1) and (2, 4).
Use two points to draw the lines.
After the lines are drawn, determine which side of the line the inequality works on. You can do this by testing points that are not on the line.
I will test each inequality using (0, 1):
y ≤ 2x + 5
0 ≤ 2 + 5
This is correct, so the inequality for y ≤ 2x + 5 will be shaded towards (0, 1).
y < -3x + 10
0 < -3 + 10
This is correct, so the inequality for y < -3x + 10 will be shaded towards (0, 1).
0 ≤ 1
This is correct, so the inequality for 0 ≤ y will be shaded upwards towards (0, 1).
The end result of this graph is all three inequalities being shaded (inwards).
The solution is a triangle with points at (1, 7), (3.33333, 0), and (-2.5, 0).

What are the slope and the y-intercept of the linear function that is represented by the graph?
On a coordinate plane, a line goes through points (negative 3, 0) and (negative 2, 4).
The slope is 3, and the y-intercept is 9.
The slope is 3, and the y-intercept is 12.
The slope is 4, and the y-intercept is 9.
The slope is 4, and the y-intercept is 12.
Answer: The slope is 4 and the y-intercept is 12.
Step-by-step explanation:
(-3,0) and (-2,4)
find the difference in the Y values 0-4=-4
find the difference in the v- values -3-(-2) =-1
Divide the y difference by the x difference -4/-1 = 4 so 4 is the slope
Now to find the y intercept, use the formula y=mx + b and plot in coordinates and slope to find the y- intercept
4= 4(-2) + b
4 = -8 + b
+8 +8
b= 12 so the y intercept is 12
now the equation will be like y = 4x + 12
(-3,0) and (-2,4)
find the difference in the Y values 0-4=-4
find the difference in the v- values -3-(-2) =-1
Divide the y difference by the x difference -4/-1 = 4 so 4 is the slope
Now to find the y intercept, use the formula y=mx + b and plot in coordinates and slope to find the y- intercept
4= 4(-2) + b
4 = -8 + b
+8 +8
b= 12 so the y intercept is 12
now the equation will be like y = 4x + 12

7. © MP.6 Be Precise Alyssa made a pink
and white striped blanket for her bed.
There are 7 pink stripes and 6 white
stripes. Each stripe is 8 inches wide.
How wide is Alyssa's blanket? Explain.
Answer:
104 Inches
Step-by-step explanation:
Alyssa's blanket contains 7 pink stripes and 6 white stripes.
Total Number of Stripes =7+6=13
Since each stripe is 8 inches wide.
The width of Alyssa's blanket will be the product of the number of stripes by the width of each stripe.
Therefore:
Width = 13 X 8 Inches =104 Inches
Alyssa's blanket is 104 Inches wide.

Answer:
g(u) = -3/2 u + 1/4
Step-by-step explanation:
Solve for v
-12u +3 = 8v +1
Subtract 1 from each side
-12u +3-1 = 8v +1-1
-12u +2 = 8v
Divide each side by 8
-12u/8 +2/8 = 8v/8
-3/2 u + 1/4 = v
v = -3/2 u + 1/4
g(u) = -3/2 u + 1/4

Trying to factor by splitting the middle term
1.1 Factoring x2-6x-1
The first term is, x2 its coefficient is 1 .
The middle term is, -6x its coefficient is -6 .
The last term, "the constant", is -1
Step-1 : Multiply the coefficient of the first term by the constant 1 • -1 = -1
Step-2 : Find two factors of -1 whose sum equals the coefficient of the middle term, which is -6 .
-1 + 1 = 0
The solutions to the equation x² + 6x + 1 = 0 are -0.177 and -5.823.
Given:
quadratic equation x² + 6x + 1 = 0
The quadratic formula states that for an equation of the form ax² + bx + c = 0, the solutions for x can be found using the following formula:
[tex]x = \dfrac{-b \pm \sqrt {(b^2 - 4ac)}}{2a}[/tex]
In our equation, a = 1, b = 6, and c = 1.
Now, let's plug these values into the quadratic formula:
[tex]x = \dfrac{-6 \pm \sqrt {(6^2 - 4(1)(1))}}{2(1)}[/tex]
x = (-6 ± √(36 - 4)) / 2
x = (-6 ± √32) / 2
Now, the two solutions for x:
1. x = (-6 + √32) / 2
= (-6 + 5.66) / 2
= -0.177
2. x = (-6 - √32) / 2
= (-6 - 5.66) / 2
-5.823
So, the solutions are -0.177 and -5.823.

Answer:
Step-by-step explanation:
Discount =5% of x = 0.05x
Price after discount = x - 0.05x = 0.95x
Tax = 5% of 0.95x = 0.05*0.95x
=0.0475x
Price including tax = 0.95x + 0.475x = 0.9975x
