Answer: 3[tex]\sqrt{5}[/tex]
Step-by-step explanation:
as you see c is the hypotenuse of the triangle that has two of the side 6 and 3
c^2=a^+b^2
c^2= 3^2+6^2
c^2=9+36
c^2=45

Step-by-step explanation:
you can't get x^2 from any other choices
Explanation:
A is x^2+4
B is 2x+4
C is x^2 +4x + x^2+4x, which gives you x^4 +8x
D is 2x+4-4, which is just 2x
E is just x+4
Solve the following system of equations by the substitution method. 2x = 10y - 8 3x + 4y + 5 = 0
Answers
Answer:
x = [tex]-\frac{41}{19}[/tex]
y = [tex]\frac{7}{19}[/tex]
Step-by-step explanation:
2x = 10y - 8
3x + 4y + 5 = 0
2x = 10y - 8
x = 5y - 4
3x + 4y + 5 = 0
3 ( 5y - 4 ) + 4y + 5 = 0
19y - 7 = 0
19y = 7
y = [tex]\frac{7}{19}[/tex]
x = 5y - 4
x = 5 ( [tex]\frac{7}{19}[/tex] ) - 4
x = [tex]-\frac{41}{19}[/tex]

-12(a-2)=-50 help help help
Answers
Answer:
a = 37/6
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Step-by-step explanation:
Step 1: Define equation
-12(a - 2) = -50
Step 2: Solve for a
Divide -12 on both sides: a - 2 = 25/6Add 2 on both sides: a = 37/6Step 3: Check
Plug in a into the original equation to verify it's a solution.
Substitute in a: -12(37/6 - 2) = -50Subtract: -12(25/6) = -50Multiply: -50 = -50Here we see that -50 does indeed equal -50.
∴ a = 37/6 is a solution of the equation.
Answer:
a = [tex]\frac{37}{6}[/tex]
Step-by-step explanation:
-12(a - 2) = -50
-12a + 24 = -50
-12a = -74
a = [tex]\frac{74}{12}[/tex] = [tex]\frac{37}{6}[/tex]

Determine of which lines, if any, are parallel or perpendicular. Explain.
Line a passes through (-2, 1) and (0,3).
Line b passes through (4,1) and (6,4).
Line c passes through (1,3) and (4,1).
Answers
Answer:
lines b and c are perpendicular
Step-by-step explanation:
Use slope
slope for parallel is the same
slope for perpendicular is negative reciprocal
line a slope- 1-3/-2-0 is -2/-2 or 1
line b slope- 1-4/4-6 is -3/-2 or 3/2
line c slope- 3-1/1-4 is 2/-3 or - 2/3
none are the same so none are parallel
- 2/3 is the negative reciprocal of 3/2 so lines b and c are perpendicular

Arc length is equal to its corresponding central angle.
That means that the arc measures 120° too.

Step-by-step explanation:
The arc length is calculated as
arc = circumference of circle × fraction of circle
= 2πr × [tex]\frac{120}{360}[/tex] ( r is the radius )
= 2π × 2 × [tex]\frac{1}{3}[/tex]

Ice thickness decreases at a rate of 0.2 meters per week. After 7 weeks,the ice is only 2.4 meters thick. What is the equation for relationship between the thickness and the number of weeks?
Answers
Answer:
The equation for relationship between the thickness and the number of weeks is f(x)=3.8 -0.2*x
Step-by-step explanation:
Ice thickness decreases at a rate of 0.2 meters per week. This can then be represented by the expression
f(x) = k - 0.2*x
where k is the thickness of the ice before the melting starts and x is the number of weeks.
After 7 weeks, the ice is only 2.4 meters thick. This means that x has a value of 7, while f (7) = 2.4. Replacing in the previous expression:
2.4=k -0.2*7
and solving you get:
2.4=k- 1.4
2.4 + 1.4= k
3.8= k
Then, the equation for relationship between the thickness and the number of weeks is f(x)=3.8 -0.2*x

The measurement of
of X?
Answers
Answer:
x = 57
Step-by-step explanation:
XZ divides <WXY into two equal parts. Which implies that:
m<ZXY = m<ZXW
Therefore:
m<WXY = 2(m<ZXY)
m<ZXY = 58°
m<WXY = 2x + 2
Plug in the values into the equation
2x + 2 = 2(58)
2x + 2 = 116
2x = 116 - 2 (subtraction property of equality)
2x = 114
x = 114/2 (division property of equality)
x = 57

Answer:
AAS
Step-by-step explanation:
AAS stands for Angle-Angle-Side. Here, you are given two angles and one side that is not included in the angles that are corresponding to the angles and side of another triangle, so they are congruent by the AAS rule.
You may be asking why the ASA (angle-side-angle) is not applicable. This is because the side in the ASA rule should be between the two angles, in this case, the 10-unit-side is not in between the two angles but rather nearer to the angle 70°, so ASA is not the right answer.

Give an example of a quadratic function that has two real solutions with a multiplicity of 2.
Answers
Answer:
The equation is;
x^2 + 4x + 4 = 0
Step-by-step explanation:
Here, we want to give a quadratic equation with a real solution that has a multiplicity of two
Generally, there are only two solutions to a quadratic equation since it is a polynomial of degree two
Since we have a multiplicity of 2, it means that the real roots are repeated
Let us have a solution of x = -2
With the multiplicity;
we have x + 2
So let us expand this
(x+2)(x+2)
= x^2 + 4x + 4
The equation is;
x^2 + 4x + 4 = 0

PROBLEM 3: Sales tax in a certain community is 7%. If the sales tax on a new car was $1400, what was the selling price of the car? Rephrase: $1400 is 7% of what number?
Answers
Answer:
$20,000
Step-by-step explanation:
Let the new car price before tax be p. If the sales tax was $1400, then the following is true: 0.07p = $1400, and p = $20,000
$1400 is 7% of the before-tax new car price, which is $20,000
Tonisha has a lemonade stand. She has $31 in expenses and wants to make $69 per day. If X represents the amount of revenue from selling lemonade,an inequality to represent the amount of revenue she would need to generate would be:_____? Tonisha needs to sell how much each day?
Answers
Answer:
x - 31 [tex]\geq[/tex] 69
Tonisha has to make at least $100 in revenue
Step-by-step explanation:
Set up the inequality:
x - 31 represents her profit
Since she wants to make at least $69 a day, use [tex]\geq[/tex] 69
So, the inequality is x - 31 [tex]\geq[/tex] 69
Then, solve for x to find how much she has to sell:
x - 31 [tex]\geq[/tex] 69
x [tex]\geq[/tex] 100
So, Tonisha has to make at least $100 in revenue
