Answer:

x = 8

z = 86

Step-by-step explanation:

6x + 46 = 13x - 10        (Because they're vertical angles)

6x - 13x = -10 - 46

-7x = -56

x = 8

6x + 46

6(8) + 46

94

z + 94 = 180

z = 86

Answer:

[tex]\boxed {\boxed {\sf 6 \pi \ radians}}[/tex]

Step-by-step explanation:

It's hard to compare degrees and radians, so we should convert, then compare.

To convert radians to degrees, we multiply by 180 over pi. This way, the pi will cancel out when dividing.

[tex]radian * \frac {180}{\pi}[/tex]

[tex]6 \pi * \frac {180}{\pi}[/tex]

[tex]\frac {1080 \pi}{\pi} \\[/tex]

[tex]1080[/tex]

6π radians is equal to 1080 degrees, which is much larger than 720 degrees, so it is the greater angle of rotation.

Answer:

Find the solutions below

Step-by-step explanation:

Given the equation

y = -x^2 + 2x + 7

y = -2x+2

Equating both expressions

-x^2 + 2x + 7 = -2x + 2

-x^2 + 2x + 7 + 2x - 2 = 0

-x^2 + 4x + 5 = 0

Multiply through by -1

x^2 - 4x - 5 = 0

Factorize

x^2 - 5x + x - 5 = 0

x(x-5)+1(x-5) = 0

(x+1)(x-5) = 0

x+1 = 0 and x - 5 = 0

x = -1 and 5

when x = -1

y = -2x+2

y = -2(-1)+2

y = 2+2

y = 4

when x = 5

y = -2(5)+2

y = -10+2

y = -8

Hence the solutions are (-1, 4) and (5, -8)

b) y = x^2-3x-27

y = x - 6

Equating both expressions

x^2-3x-27 = x - 6

x^2-3x-27 - x + 6 = 0

x^2-4x-21 = 0

x^2 - 7x + 3x - 21 = 0

x(x-7)+3(x-7) = 0

(x+3)(x-7) = 0

x = -3 and 7

when x = -3

y = -3-6

y = -9

when x = 7

y = 7 - 6

y = 1

Hence the required solutions are (-3, -9) and (7, 1)

Edmentum Answer

Answer: D) 14.3%

Step-by-step explanation:

Conditional probability formula:

[tex]P(B |\text{given that A}) =\dfrac{P(A\ and\ B)}{P(A)}[/tex]

So, The probability he or she was dissatisfied, given that he or she had hip surgery = [tex]\dfrac{\text{Number of persons are dissatisfied and has hip surgery}}{\text{Total persons have hip surgery}}[/tex]

From the table, the number of persons who are dissatisfied and has hip surgery = 15

Total persons have hip surgery = 105

Required probability = [tex]\dfrac{15}{105}\approx0.143[/tex]

In percent, Required probability = 14.3%

Correct option D) 14.3%

Answer: are perpendicular

Step-by-step explanation:

Two lines intersecting at a right angle are said to be perpendicular. When the lines cross each other, we say the lines have intersected.

The point of intersection of the lines is the pointe where they cross one another. In case the lines never interesct, such lines are refered to as the parallel lines.

Answer: 78.5 in2

Step-by-step explanation:

Given:

The x and y axis are tangent to a circle with radius 3 units.

To find:

The standard form of the circle.

Solution:

It is given that the radius of the circle is 3 units and x and y axis are tangent to the circle.

We know that the radius of the circle are perpendicular to the tangent at the point of tangency.

It means center of the circle is 3 units from the y-axis and 3 units from the x-axis. So, the center of the circle is (3,3).

The standard form of a circle is:

[tex](x-h)^2+(y-k)^2=r^2[/tex]

Where, (h,k) is the center of the circle and r is the radius of the circle.

Putting [tex]h=3,k=3,r=3[/tex], we get

[tex](x-3)^2+(y-3)^2=3^2[/tex]

[tex](x-3)^2+(y-3)^2=9[/tex]

Therefore, the standard form of the given circle is [tex](x-3)^2+(y-3)^2=9[/tex].

Answer:

okokookokokokjfdgugv

Answer:

The mistake they made was they switched the slope and y-intercept.

The correct answer is y=2x+7 because when we write an equation in slope intercept form (y=mx+b) you replace m with the slope and b with the y-intercept.

Answer:

Equation B, 10 + 5.50n = y.

Step-by-step explanation:

N is the pounds of shrimp that were purchased. This has no set value, it can change at any time.

Since each pound of shrimp is $5.50, if you wanted to buy 10 pounds of fish you'd pay $55.

If I wanted to write an equation to find the total amount of money that I'd need to pay for n pounds of shrimp, I would use the equation 5.50n. (I don't know if this makes sense lol I'm terrible at explaining ;-;)

Now, it states that he wants an extra 10 dollars to pay for expenses. On top of the 5.50n, he wants an extra $10.

You need to add 10 to 5.50, in order to get the total amount, or y.

The final equation is going to be 5.50n + 10 = y, or choice B.

Answer:

Step-by-step explanation:

double negative is a plus sign

13--9=22

Answer: 22

Step-by-step explanation:

Here, we need to know the concept of changing signs. Under any circumstances, if there is a "-" sign outside of parenthesis, the signs inside need to be the opposite. If you are still not very clear, I can provide some examples below:

-------------------------------------------------------

Given

13 - (-9)

⇒There is a "-" sign outside

⇒We need to convert the sign inside "-" to "+"

⇒13+9

⇒22
