Answer:
D infitently Many
Step-by-step explanation:
A system of linear equations usually has a single solution, but sometimes it can have no solution (parallel lines) or infinite solutions (same line). This article reviews all three cases. One solution. A system of linear equations has one solution when the graphs intersect at a point.
30 ft. tall. You must find the ratios and compare. 2/20=3/x The best way I know to do this is to cross multiply. 2 times x and 20 times 3. So, 2x= 60. Divide by 2 and you get x =30. The height of the tree would be 30 ft. You could also find the proportion. 20/2= 10, so the height,x, over 3 would be equal to 10. 3 times 10 is equal to 30.
Answer:
58 cm³
Step-by-step explanation:
the volume (V) of a pyramid is calculated using the formula
V = 
× area of base × height
= × 5² × 7 ≈ 58 cm³
Answer:
y = 4/5x + 32/5
Step-by-step explanation:
(-3,4) and (2, 8)
Slope:
m=(y2-y1)/(x2-x1)
m=(8-4)/(2+3)
m= 4/5
Slope-intercept:
y - y1 = m(x - x1)
y - 4 = 4/5(x + 3)
y - 4 = 4/5x + 12/5
y = 4/5x + 32/5
