Answer is b. 105 degrees
explanation:
a straight line is 180 degrees.
35+40=75
180-75=105
Metric system is standard or measurement developed in 1670's by Gabriel Mouton. This is a decimal system of measurement for length, mass and volume. The SI unit of length is meters. In the metric system, the spectrum for the units of length is
km hm dkm m dm cm mm
The greatest starts from the left side" kilometer(km), hectometer(hm), decameter (dkm), meter (m), decimeter (dm), centimeter (cm) and millimeter (mm). The same prefixes are applied to units of mass in grams and volume in liters, like milligrams and milliliters. To use the metric system, place 77 mm above the mm scale. To convert it to m, you have to move the decimal place 3 places to the left. Use the scale to guide you. Hence, 77 millimeters is equal to 0.077 meters.
One foot is defined as 0.3048 meters.
Y-intercept, where the graph crosses y-axiss is 0. that means in the equation: y = mx + b
b = 0
the m, is slope. looking at the graph you can see the points on the line are connect up 4 right 1. rise/run = slope = 4
y = 4x
Answer:
(95/31, -118/31)
Step-by-step explanation:
-7x-8y=9
4x+9y=-22
----------------
4(-7x-8y)=4(9)
7(4x+9y)=7(-22)
-----------------------
-28x-32y=36
28x+63y=-154
-----------------------
31y=-118
y=-118/31
-7x-8(-118/31)=9
-7x+944/31=9
-7x=9-944/31
-7x=279/31-944/31
-7x=-665/31
7x=665/31
x=(665/31)/7
x=(665/31)(1/7)
x=665/217=95/31
x=95/31, y=-118/31
