6 = 2 - 2x + 10
x = ?
Answer:
3
Step-by-step explanation:
6 = 2 - 2x + 10
6 - 2 = -2x + 10
4 = -2x + 10
4 - 10 = -2x
-6 = -2x
-6/2 = -2x/2
-3 = -x
-3/-1 = -x/-1
3 = x
x = 3

Enter your answer as a decimal in the box.
Answer:
The first x = 4
The second x = 6.25
Step-by-step explanation:
For the first question. We need to make use of the midsegment theorem which says, if you have a trapezoid with base1 and base2, then the midsegment is given as:
(Base1 + Base 2)/2.
We are given Base 1 = 5x + 3 and Base 2 = 12x – 3 and the midsegment, JK = 34. To find x we have:
(5x + 3 + 12x – 3)/2 = 34
This gives: 17x/2 = 34.
Therefore, x = (34 x 2)/17 = 4. Thus, x = 4.
As for the second question, we have two diagonals of the rectangle, FH and JG. We are given that JG = 40. We know that the diagonals of the rectangle are equal, therefore FH = 40 as well.
We are told that M is the midpoint, meaning FM is half of the diagonal FH. Mathematically this can be written as:
FM = FH/2
Given that FM = 3.2x and FH = 40, we have:
3.2x = 40/2
3.2x = 20
x = 20/3.2
x = 6.25

(z^2 + 11z + 18 / z^2 + 14 z + 45) multiplied by (z^2 + 8z + 15 / z^2 + 2z)
Show steps too if you can!
Answer:
[tex] \dfrac{z + 3}{z} [/tex]
Step-by-step explanation:
[tex] \dfrac{z^2 + 11z + 18}{z^2 + 14 z + 45} \times \dfrac{z^2 + 8z + 15}{z^2 + 2z} = [/tex]
Multiply the numerators. Multiply the denominators.
[tex] = \dfrac{(z^2 + 11z + 18)(z^2 + 8z + 15)}{(z^2 + 14 z + 45)(z^2 + 2z)} [/tex]
Factor every polynomial.
[tex] = \dfrac{(z + 2)(z + 9)(z + 5)(z + 3)}{(z + 5)(z + 9)z(z + 2)} [/tex]
Divide the numerator and denominator by equal factors.
[tex] = \dfrac{z + 3}{z} [/tex]

Ailani draws a map of her local town. She places the town hall at the origin of a coordinate plane and represents a lake
with a circle drawn on the map. The center of the lake is 19 miles east and 3 miles south of the town hall, and the
radius of the lake is 0.5 miles.
If the positive x-axis represents east and the positive y-axis represents north, which equation represents the lake?
O (x + 19)2 + (y - 3)2 = 0.5
O (x – 19)2 + (y + 3)2 = 0.5
O (x + 19)2 + y - 3)2 = 0.25
O (x - 19)2 + ( + 3)2 = 0.25
T
The equation of the lake with a center 19 miles east and 3 miles south with radius of 0.5 miles is (x + 19)² + (y + 3)² = 0.25
What is an equation?An equation is an expression that shows the relationship between two or more variables and numbers.
The equation for a circle is given as:
(x - h)² + (y - k)² = r²
Where (h, k) is the center of the circle and r is the radius.
The center of the lake is 19 miles east and 3 miles south, i.e. (-19, -3) and the radius is 0.5 miles.
The equation of the lake is:
(x - (-19))² + (y - (-3))² = 0.5²
(x + 19)² + (y + 3)² = 0.25
The equation of the lake with a center 19 miles east and 3 miles south with radius of 0.5 miles is (x + 19)² + (y + 3)² = 0.25

Answer: D. [tex](x-19)^2+(y+3)^2=0.25[/tex]
Step-by-step explanation:
Let's review what we know:
the lake is circularthe town hall is at the originthe center of the lake is 19 miles east of the origin and3 miles south of itthe radius of the lake is 0.5 milesA circle can be depicted on the coordinate plane with the equation [tex](x-h)^2+(y-k)=r^2[/tex], where:
(h, k) is the center of the circleand r is the radius of the circle19 miles east of the origin would be 19 units to the right of the origin on the coordinate plane, as east is the rightwards direction in real life. In short, h = 19.
Let's plug in that value: [tex](x-(19))^2+(y-k)^2=r^2[/tex].
So we know that the x-coordinate defining part of the equation would have to be [tex](x-19)^2[/tex].
Meanwhile, 3 miles south of the origin would be modeled as three units underneath it, because south would be considered "downwards". The y-value (k) would be negative 3.
Putting what we have so far together, the center of the circle would be (19, -3).
Therefore, the y-coordinate defining part of the equation would be [tex](y+3)^2[/tex].
Here's what the equation looks like with the work we've completed so far: [tex](x-19)^2+(y+3)^2=r^2[/tex]
Finally, let's plug in the radius value 0.5.
0.5 * 0.5 = 0.25
Ailani would use the equation [tex](x-19)^2+(y+3)^2=0.25[/tex] to model the lake in relation to the town hall. I hope that makes sense!
