Answer:
1) x = -1 or x = -10 (either of them are both correct)
2) x = 3 or x = -5
Step-by-step explanation:
Let's solve your equation step-by-step.
x2 + 11x + 10 =0
Step 1: Factor left side of equation.
(x + 1)(x + 10) = 0
Step 2: Set factors equal to 0.
x + 1 = 0 or x +10 = 0
x = −1 or x = −10
Answer:
x = −1 or x = −10
2x^2 + 4x − 30 = 0
Answer:
x = 3 or x = −5

Find the distance between the complex numbers. z1 = 9 - 9i z2 = 10 - 9i
Answers
Answer:
The distance between the two given complex numbers = 9
Step-by-step explanation:
Explanation:-
Step(i):-
Given Z₁ = 9 - 9 i and Z₂ = 10 -9 i
Let A and B represent complex numbers Z₁ and Z₂ respectively on the argand plane
⇒ A = Z₁ = x₁ +i y₁ = 9 - 9 i and
B = Z₂ = x₂+ i y₂ = 10 -9 i
Let (x₁ , y₁) = ( 9, -9)
(x₂, y₂) = (10, -9)
Step(ii):-
The distance between the two points are
A B = [tex]\sqrt{(x_{2} - x_{1})^{2}+(y_{2} - y_{1})^{2} }[/tex]
A B = [tex]\sqrt{(10 - 1)^{2}+(-9 - (-9))^{2} }[/tex]
AB = [tex]\sqrt{(9)^{2} +(-9+9)^{2} }[/tex]
AB = √81 = 9
Conclusion:-
The distance between the two given complex numbers = 9

Tracy has a cell phone plan that provides 250 free minutes each month for a

Which of the following piecewise functions represents charges based on
Tracy's cell phone plan?
29,45 250 1
O A. f(x) =
| 35x,x > 250)
B. f(x)=

O C. f(x)={ 29, x>250
129+. 35x, x5 250
29,7 $250
O D. f(x) =
129+.35(x-250),x > 250)
Answers
Answer:
[tex]f(x)=\left \{ {{29\,\,for \,\,x\,\leq 250 } \atop {29+0.35(x-250)\,\,for \,x>250}} \right.[/tex]
Step-by-step explanation:
If we call "x" the number of call minutes used with this plan, the piecewise function used to describe it must represent;
a) a constant value of 29 for any x value smaller than or equal to 250
b) a line with positive slope of 0.35 for the region with x larger than 250. The mathematical representation of such increasing straight line, should be given by a line of slope m = 0.35, and containing the point (250, 29) which is the starting point for this right hand side portion of the domain:
[tex]f(x)=0.35(x-250)+29\\f(x)=0.35 x-87.5+29\\f(x)=0.35 x-58.5[/tex]
So the function should look like:
[tex]f(x)=\left \{ {{29\,\,for \,\,x\,\leq 250 } \atop {29+0.35(x-250)\,\,for \,x>250}} \right.[/tex]
or as shown above, in a more simplified form:
[tex]f(x)=\left \{ {{29\,\,for \,\,x\,\leq 250 } \atop {0.35x-58.5\,\,\,for \,\,x>250}} \right.[/tex]

of the day, the total amount of money from tickets sold was $240. Which equation could
be used to determine x, the number of tickets Xavier sold ?
A. 12(X + 8) = 240
B. X(12 + 8) = 240
C. 12 + 8x = 240
D. 12x + 8 = 240
Answers
Answer: 12(X+8)=240
Step-by-step explanation: We then would have to do the distributive property and you end with 12x+96=240
Subtract 96 from each side
Then you end with
12x=144
You then divide 12 from each side and see that X=12!

The answer would be [tex]3^{2}[/tex].
Step-by-step explanation:
-Solve the following equation:
[tex]3^{-6} \times ( 3^{4} \div 3^{0})^{2}[/tex]
-When dividing integers, the exponents would subtract each other. So, you subtract exponent [tex]0[/tex] and [tex]4[/tex]:
[tex]3^{-6} \times ( 3^{4} \div 3^{0})^{2}[/tex]
[tex]3^{-6} \times ( 3^{4})^{2}[/tex]
-Simplify [tex]3^{4}[/tex] by the exponent [tex]2[/tex]:
[tex]3^{-6} \times ( 3^{4})^{2}[/tex]
[tex]3^{-6} \times 3^{8}[/tex]
-When multiplying integers, the exponent would add up together. So, you would add [tex]-6[/tex] and [tex]8[/tex]:
[tex]3^{-6} \times 3^{8}[/tex]
[tex]3^{2}[/tex]
So, the answer is [tex]3^{2}[/tex].
The lunch lady has 4 pounds of lasagna. If she makes 1/3-pound servings using this amount of lasagna, how many servings can she make?
Answers
4/(1/3) = 12 servings
We can think about this in two ways:
Firstly, you can split up 4 pounds into 1/3-size pieces, and to find out how many you would need you would then have to divide 4 by 1/3:
4/1 ÷ 1/3
4/1 × 3/1 = 12/1 = 12 servings.
You can also think of it as how many 1/3-size pieces make up 1 pound, which is 3 because 3 × 1/3 = 1. Therefore you need 3 × 4 = 12 pieces.

Answers
Step-by-step explanation:
x:y=3:7
x+y=180
3+7=10
180/10=18
to find x
18*3=54
x+10+z=180
54+10+z=180
64+z=180
z=180-64
z=116°
The measure of angle z of the cyclic quadrilateral will be 116 degrees.
What is a cyclic quadrilateral?If the quadrilateral is inscribed in a circle then the quadrilateral is known as a cyclic quadrilateral.
A cyclic quadrilateral is shown.
x / y = 3 / 7
y = 7x / 3
We know that the sum of the opposite angles of the cyclic quadrilateral is 180 degrees. Then the equation will be
x + y = 180°
x + 7x/3 = 180°
10x/3 = 180°
x = 54°
Then another equation is given as,
x + 10° + z = 180°
54° + 10° + z = 180°
z = 116°
The measure of angle z of the cyclic quadrilateral will be 116 degrees.

What is the solution to the inequality Ix-4| <3
-7
1
X<-7 or x < -1
x> 1 or x<7
Answers
Answer:
see explanation
Step-by-step explanation:
Inequalities of the form | x | < a have solutions of the form
- a < x < a
Given
| x - 4 | < 3 , then
- 3 < x - 4 < 3 ( add 4 to the 3 intervals )
1 < x < 7
Thus x > 1 or x < 7
The solution of the given inequality is x < 7 or x > 1.
To solve the inequality Ix - 4| < 3, we can break it down into two cases: when the expression inside the absolute value is positive and when it is negative.
Case 1: x - 4 > 0
In this case, we don't need to consider the absolute value because the expression inside it is already positive.
So we have:
x - 4 < 3
Adding 4 to both sides:
x < 3 + 4
x < 7
Case 2: x - 4 < 0
In this case, the expression inside the absolute value is negative, so we need to negate it when removing the absolute value. Therefore, we have:
-(x - 4) < 3
Expanding the negation:
-x + 4 < 3
Subtracting 4 from both sides:
-x < 3 - 4
-x < -1
Dividing both sides by -1 and flipping the inequality sign:
x > 1
Combining the results from both cases, we have the solution:
x < 7 or x > 1
In interval notation, the solution is (-∞, 1) U (7, +∞).
Hence the solution of the given inequality is x < 7 or x > 1.
