Answer:
? = 105
Step-by-step explanation:
Use similar triangles and law of proportions.
?/56 = 120/64
?/56 = 15/8
8 * ? = 56 * 15
? = 7 * 15
? = 105
The slope for 1 is 3/9 or 1/3 so the equation can be y-0=1/3(x-0)
and for 2 the slope is -2/-8 or 1/4 and the equation is y-0=1/4(x-0)
The answer to this is B:8
Answer:
nitrogen
Step-by-step explanation:
By far, the most abundant gas in the Earth's atmosphere is nitrogen, which accounts for about 78% of the mass of dry air. Oxygen is the next most abundant gas, present at levels of 20 to 21%
Y-intercept is (0,4−8 squared ) no x intercepts
