Answer:
Answer=44
Step-by-step explanation:
Rectangle: 6x4=24.
Triangle: 4x4=16, and 16/2=8.
Semicircle: Pi x radius squared, so pi x 2 squared is 16.something, and since it's a semicircle, we divide by 2, so it's 8 again.
Overall: 24+8+8=44 cm squared.
Let they be x.
Cost of textbooks + laptops cant greater than total amount.
(cost of 1 textbooks * number of textbooks) + (cost of 1 laptop * number of laptops ≤ 6500
(30*116) + (x*439) ≤ 6500
3480 + 439x ≤ 6500
439x ≤ 3020
x ≤ 6.8(approx)
Last natural number is 6, says, they can buy 6 laptops at max.
Plug in “0” for y, rearrange and solve.
Remember when you want to find the intercept of a variable, you plug in 0 for the opposite variable. Same goes for finding the x intercept.
When you want to find…
Y intercept: X=0
X intercept: Y=0
Answers:
X int= -6 or (-6,0)
Y int=2 or (0,2)
(x,1) (y,-2) your welcome ....
Y = mx + b is the slope intersect form.
so 8x - 7y = 23
-7y = -8x + 23
y = -8x/-7 + 23/-7
y = 8/7x - 23/7 Ans
