Answer:
y = 2x - 1
Step-by-step explanation:
Slope
for every increase of 3 in x
there's an increase of 6 in y
m = rise/run
m = 6/3
m = 2
----------------------------
Slope intercept form is
y = mx + b
To find "b" plug in m = 2 and any of the given points
using (1, 1)
1 = 2(1) + b
1 = 2 + b
b = -1
The equation is
y = 2x - 1
This is for 6^7 and ill comment the next one
Answer:
therefore 1. 100 square feet and 2. 270 square feet
Step-by-step explanation:
1. Area for trapezium is (a+b)/2 times height
= 100
2. Area for kite is ab/2 where a and be are the perpendicular diagonals:
Answer:
92 sq. inches
Step-by-step explanation:
Total paper required = total surface area
Surface area of a cuboid = 2[(l×b) + (l×h) + (b×h)],
Where 'l' is the length, 'b' is the breadth and 'h' is the height
For the box, total surface area = 2[(8×3) + (3×2) + (8×2)]
=2[24 + 6 + 16]
=2[46]
= 92 sq. inches
Answer:
Formula : (n-2) 180
Step-by-step explanation:
12 sides: (12-2) 180
12-2=10
10 * 180= 1800
In the formula the n is the number of sides. Use this formula to solve the first few questions.
