Answer:
(4,-25)
Step-by-step explanation:
I graphed this on the desmos graphing calculator.
Write the equation of the graph which is the reflection of y=−|x−1|−1 about the origin
Answer:
f(x) = |x + 1| + 1
Step-by-step explanation:
A reflection over the y-axis followed by a reflection over x-axis is equivalent to a reflection about origin.
f(x) = -|x-1| -1
reflection over the x-axis:
-f(x) = (-1)*(-|x-1| -1) = |x-1| +1
reflection over the y-axis of the previous function:
-f(-x) = |-x-1| +1 = |x + 1| + 1
which is the reflection of f(x) about the origin

To rationalize the denominator of [tex]\frac{2\sqrt{10} }{3\sqrt{11} }[/tex] you should multiply the expression by [tex]\frac{\sqrt{11} }{\sqrt{11} }[/tex]
Given the surd function:
[tex]\frac{2\sqrt{10} }{3\sqrt{11} }[/tex]Rationalizing surd functions means multiplying the numerator and denominator of such function by the conjugate of the denominator.For the surd function given, to rationalize it, we only need to multiply the numerator and denominator by √11 as shown:
[tex]=\frac{2\sqrt{10} }{3\sqrt{11} }\times \frac{\sqrt{11} }{\sqrt{11} } \\=\frac{2\sqrt{110}}{3(11)}\\= \frac{2\sqrt{110}}{33}\\[/tex]
Hence we can conclude that to rationalize the denominator of [tex]\frac{2\sqrt{10} }{3\sqrt{11} }[/tex] you should multiply the expression by [tex]\frac{\sqrt{11} }{\sqrt{11} }[/tex]

Answer:
x = (3 − √5) / 2, (3 + √5) / 2, and 1
Step-by-step explanation:
Using rational root theorem, ±1 are possible roots. By trial and error, we find that +1 is a root. Therefore, x − 1 is a factor. Knowing this, we can use grouping or long division. Using grouping:
x⁴ − 5x³ + 8x² − 5x + 1 = 0
x⁴ − 5x³ + 4x² + 4x² − 5x + 1 = 0
x² (x² − 5x + 4) + 4x² − 5x + 1 = 0
x² (x − 4) (x − 1) + (4x − 1) (x − 1) = 0
(x² (x − 4) + 4x − 1) (x − 1) = 0
(x³ − 4x² + 4x − 1) (x − 1) = 0
Repeating the process, possible rational roots of x³ − 4x² + 4x − 1 are ±1. We already know -1 isn't a root. By trial and error, we find that +1 is again a root. Using grouping to factor:
(x³ − 4x² + 3x + x − 1) (x − 1) = 0
(x (x² − 4x + 3) + x − 1) (x − 1) = 0
(x (x − 3) (x − 1) + x − 1) (x − 1) = 0
(x (x − 3) + 1) (x − 1) (x − 1) = 0
(x² − 3x + 1) (x − 1)² = 0
To find the roots of x² − 3x + 1, we use the quadratic formula.
x = [ -(-3) ± √((-3)² − 4(1)(1)) ] / 2(1)
x = [ 3 ± √(9 − 4) ] / 2
x = (3 ± √5) / 2
So the roots are x = (3 − √5) / 2, (3 + √5) / 2, and 1.

A scientist has two solutions, which she has labeled Solution A and Solution B. Each contains salt. She knows that Solution A is 70% salt and Solution B is 95% salt. She wants to obtain 50 ounces of a mixture that is 80% salt. How many ounces of each solution should she use?
Answer:
30 ounces of solution A
20 ounces of solution B
Step-by-step explanation:
x ounces of solution A
y ounces of solution B
x + y = 50
0.7x ounces of salt in the solution A
0.95y ounces of salt in the solution B
0.8*50 = 40 ounces of salt in 50 ounces of 80% solution
0.7x + 0.95y = 40
x + y = 50
0.7x + 0.95y = 40
x= 50 - y
0.7(50 - y) + 0.95y = 40
35 - 0.7y + 0.95y = 40
0.25y = 5
y = 20 ounces of solution B
x = 50 - y = 50 - 20 = 30 ounces of solution A
Solve the given equation for x. 8−65x=10
Answer:
Exact form is [tex]x=-\frac{2}{65}[/tex]
And the decimal form is x = −0.0307692
Answer:
The value of x is -2/65
Step-by-step explanation:
The given equation is
8 - 65x = 10
We are asked to find the value of x.
Step 1: Subtract 8 from both sides
-8 + 8 - 65x = 10 - 8
-65x = 2
Step 2: Divide both sides by -65
-65x/-65 = 2/-65
x = -2/65
Therefore, the value of x is -2/65

How do I find the surface area?
Answer:
Surface area is the sum of the areas of all faces (or surfaces) on a 3D shape. A cuboid has 6 rectangular faces. To find the surface area of a cuboid, add the areas of all 6 faces. We can also label the length (l), width (w), and height (h) of the prism and use the formula, SA=2lw+2lh+2hw, to find the surface area.

There is a common difference d between consecutive terms, that is
d = - 1 [tex]\frac{1}{2}[/tex] -(- [tex]\frac{1}{2}[/tex] ) = - 1
d = - 2 [tex]\frac{1}{2}[/tex] - (- 1 [tex]\frac{1}{2}[/tex] ) = - 1
d = - 3 [tex]\frac{1}{2}[/tex] - (- 2 [tex]\frac{1}{2}[/tex] ) = - 1

[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - [tex]\frac{1}{2}[/tex] and d = - 1 , thus
[tex]a_{n}[/tex] = - [tex]\frac{1}{2}[/tex] - 1 (n - 1) = - [tex]\frac{1}{2}[/tex] - n + 1 = [tex]\frac{1}{2}[/tex] - n , where n = 1, 2, 3, 4, ......

The taco truck sells tacos for $3 and burritos for $4 . The number of items sold on a Tuesday is 125 with a total income of $425. How many tacos were sold?
Answer: 75 tacos
Step-by-step explanation:
Hi, to answer this question we have to write a system of equations:
3 T + 4 B =425
T + B = 125
Where T is the number of tacos sold, and B is the number of burritos sold.
Multiplying the second equation by 3, and subtracting it to the first equation:
3 T + 4 B =425
3T + 3B = 375
___________
B =50
Replacing B in any equation:
T + B = 125
T +50 =125
T =125-50
T = 75
