Answer:
-772
Step-by-step explanation:
First, multiply the brackets with the numbers before them:
4(-) = -4
-32(22-) = -704-
2(-) = -2
Then put them back into the question
-4 - 62 - 704 - 2
Subtract them to get the answer
-4 - 62 - 704 - 2 = -772

Answer:
(c) (-6, 1)
Step-by-step explanation:
The answer choices suggest the missing point is in the 2nd quadrant and below the given point in that quadrant. (All the x-values are negative, and the y-values are less than 6.)
There are at least a couple of ways you can find this point. We choose to consider the points of the opposite side: the two points in the first quadrant.
The bottom of these is 2 units left of the top one, and 5 units below it. (You can determine this by counting grid squares or by comparing coordinates.)
So, a point 2 left and 5 below the upper left point (-4, 6) will have coordinates ...
(-4, 6) +(-2, -5) = (-4-2, 6-5) = (-6, 1) . . . . the missing point
_____
Alternative solution
The midpoints of the diagonals of a parallelogram are the same point, so the sum of coordinates at the ends of each diagonal will be the same. This means you can find the missing point (D) using A+C-B = D, where A, B, C are the given points labeled clockwise from upper left.
D = A +C -B = (-4, 6) +(1, 2) -(3, 7) = (-4+1-3, 6+2-7)
D = (-6, 1)
__
Additional comment
This relation between point coordinates is true regardless of how the given points are labeled. A different labeling will give a different point D, meaning 3 points can be the vertices of 3 different parallelograms. That is why we start this answer with a comment regarding where we expect the 4th point to be.

Answer:
68. (-1, 0)
69. (0, 2)
70. (2, -1)
Step-by-step explanation:
The solution is the ordered pair (x, y) where the lines intersect. The graphs have no scale, so we must assume 1 grid space corresponds to 1 unit.
The first coordinate of the pair is the horizontal distance from the y-axis. Positive is to the right. The second coordinate of the pair is the vertical distance from the x-axis. Positive is up.
68. The point of intersection is 2 left of the origin on the x-axis. x=-2, y = 0.
(x, y) = (-2, 0)
__
69. The point of intersection is 2 up from the origin on the y-axis: y = 2, x = 0.
(x, y) = (0, 2)
__
70. The point of intersection is 2 right and 1 down from the origin: x = 2, y = -1.
(x, y) = (2, -1)

Find the area of the shaded region. Round your answer to the nearest hundredth.
12=side length
The area of the shaded region is about — square units.
How do you find the area of the shaded region? Thank you!
Answers
Answer:
Step-by-step explanation:
Divide 360 by the number of sides in a regular polygon to find θ
θ = 360/5 = 72°
Use law of cosines to find the radius of the circle which equals the common length sides of the isosceles triangle
12² = R² + R² - 2•R•Rcos72
12² = 2R² - 2R²cos72
12² = 2R²(1 - cos72)
R² = 12² / 2(1 - cos72)
R² = 104.1993788...
R = 10.2078...
The height of the isosceles triangle is
h = Rcos(θ/2) = 10.2078cos(72/2) = 8.258291...
The shaded area is the area of the circle minus the area of the pentagon.
A = π(104.1993) - 5(½(12)(8.258291))
A = 327.35200... - 247.74874...
A = 79.6032575...
A = 79.60 units²
The Area of the shaded region is A = 79.60 units²
What is law of Cosine?A planar triangle's side's square is equal to the sum of the squares of the other sides minus the product of those sides and the cosine of the angle that separates them by two.
Given:
length= 12
So, Divide 360 by the number of sides in a regular polygon
θ = 360/5
θ = 72°
Use law of cosines
12² = R² + R² - 2 x R x Rcos72
12² = 2R² - 2R² cos72
12² = 2R²(1 - cos72)
R² = 12² / 2(1 - cos72)
R² = 104.1993788...
R = 10.2078...
Thus, the height of the isosceles triangle is
h = R cos(θ/2)
= 10.2078cos(72/2)
= 8.258291...
and, the shaded area is
A = π(104.1993) - 5(½)(12)(8.258291))
A = 327.35200 - 247.74874
A = 79.6032575
A = 79.60 units²

To solve for the value of a, you have to isolate “a“ on one side.
-5a - 2.2 < 17.8
Add 2.2 to both sides.
-5a < 20
Divide both sides by -5. Note: when you are dividing by a negative number, the direction of the sign switches.

What is the area of a rectangle with vertices at (−4, 0), (−3, 1) , (0, −2), and (−1, −3)?
don't round any side lengths plz
Answers
Answer:
6
Step-by-step explanation:
If you plot all 4 points, you will see that they are given in clockwise order around the rectangle.
If you take (-3, 1) and find the distance to (-4, 0), and take again (-3, 1) and find the distance to (0, -2), you will have the lengths of two consecutive sides. These sides can then be used as length and width to find the area.
distance from (-3, 1) to (-4, 0):
d = √[(-3 - (-4))² + (1 - 0)²] = √[1² + 1²] = √2
distance from (-3, 1) to (0, -2):
d = √[(-3 - 0)² + (1 - (-2))²] = √[(-3)² + 3²] = 3√2
area = LW = √2 × 3√2 = 3 × 2 = 6

Write the equation of the line that passes through the points (8,3) and (7,3). Put your answer in fully reduced point-slope form, unless it is a vertical or horizontal line
Answers
Step-by-step explanation:
the equation :
(y-3)/(3-3) = (x-8) /(7-8)
(y-3) /0 = (x-8) /(-1)
(-1)(y-3) = 0(x-8)
-y +3 = 0
y = 3
(this is a horizontal line)
Answer:
y = 3 (Horizontal line)
Step-by-step explanation:
point: (8, 3) and (7, 3)
(y - y1)/(y2 - y1) = (x - x1)/(x2 - x1)
(y - 3)/(3 - 3) = (x - 8)/(7 - 8)
(y - 3)/0 = (x - 8)/(-1)
(-1)(y - 3) = 0
-y + 3 = 0
-y = - 3
y = 3 (Horizontal line)
The value of Y varies jointly with x and z, and Y=60 when x=3 and z=5. find the equation that represents this relationship
