Answer:
a) y-2=1/2(x-6) b) The y-intercept of this line is -1.
Step-by-step explanation:
y-y1=m(x-x1)
y-2=1/2(x-6)
------------------
y=1/2x-6/2+2
y=1/2x-3+2
y=1/2x-1
y=mx+b where m=slope and b=y-intercept.
B) 7n−3=n+4
In this case, 'n' is used in place of the word 'number'. 'Product' refers to multiplication, so we multiply n by 7. 3 LESS refers to subtraction, so we subtract 3 from 7n. Then, we know that the solution to that is four more than what the actual number is. MORE refers to addition, so we add 4 to n.
Answer:
S = 85cm^2
Step-by-step explanation:
The surface area of a square pyramid is given by the following formula:

where it has taken into account the sum of the area of a square and four triangles:

h: slant height = 6cm
b: base = 5cm
By replacing in the formula you obtain:

hence, the surface area is 85cm^2
Answer:
6150 pounds
Step-by-step explanation:
we know 1 ton = 2000 pounds
so 3 tons + 150 pounds
= 3 x 2000 + 150
= 6000 + 150
= 6150 pounds
