Y - y1 = m(x - x1)
slope(m) = -8/7
(4,4)...x1 = 4 and y1 = 4
sub
y - 4 = -8/7(x - 4) <== answer C

Sophie says that if the interior angle of a triangle is 65 degrees and the exterior one is 295 degrees. Comment on her thinking

Yuri [45]

Sophie is correct because 295 + 65 = 360 and 360 is the # of degrees in a full circle

Answer:

8π in

64π mm²

Step-by-step explanation:

The circumference of a circle is equal to 2πr, where r is the radius.

2π(4) = 8π ≈ 25.132

The area of a circle is equal to πr²

π(8)² = 64π ≈ 201.062

The system of equations is graphed on the coordinate plane. y=−12x−1y=14x−4 A graph with a blue line passing through coordinates

Anika [276]

We have that

case 1)
system of equations is
y=−12x−1
y=14x−4

using a graph tool
see the attached figure

the solution of the system is the point (0.115,-2.385)

case 2)
system of equations is
blue line passing through coordinates A (0, -4) and B (4, -3)
red line passing through coordinates C(0, -1) and D (4, -3)

using a graph tool
see the attached figure

the solution of the system is the point (4,-3)

The following set of coordinates represents which figure? (1, 1), (5, 3), (7, 7), (3, 5) (4 points)

slamgirl [31]

Check the slopes
the first 2 points have slope (3-1) / (5-1) = 2/4 = 1/2
points 2 and 3 slope = 4/2 = 2
3 and 4:- slope = -2/-4 = 1/2
4 and 1:- slope = 4/2 = 2

so we have 2 pairs of opposite sides which are parallel

looks like a parallelogram or a rhombus

if adjacent sides are equal its a rhombus

length betwee pts 1 and 2 = sqrt(2^2 + 4^2) = sqrt20
.. ... ... .. .. .. ...2 and 3 = sqrt(4^2 + 2^2) = sqrt20

so it is a rhombus
