Answer:
b=320; slope=-30
Step-by-step explanation:
if you look along the y-axis find the spot that the line intercepts and then that's b
now for the slope
find two points on the line, i chose(8 , 120) and (4 , 240)
use the slope formula: y2-y1 over x2-x1
240-120=120 and 4-8= -4
so the slope is 120/-4 and that can be simplified to 30/-1 or -30
Answer:
see below
Step-by-step explanation:
1. yes
2. no, 4.82 x 10^4
3, no, 9.9 x 10^-4
4. no, 3.6 x 10^6
5. yes
6. no, 7.8 x 10^-4
Tetrahedron has 4 faces so it's a pyramid, dodecahedron is 12 faces, octahedron is 8 faces, icosahedron has 20 faces. Easiest way I know to classify them
4½ = 9/2
1 2/5 = 7/5
9/2 * 7/5 = 63/10 = 6 3/10
Answer:
b= 55 degrees
c= 125 degrees
Step-by-step explanation:
So angle B and 55 degree angle are vertical angles to they are congruent and opposite
Angle C and angle b =180 so subtract 55 from 180 to get missing angle C as 125 degrees
