Answer:
y = 8x + 2
Step-by-step explanation:
Slope interrcept form is
y = mx + b
m is the slope = 8
b is the y-intercept = 2
y = 8x + 2
Answer:
If they have the same slope, then there will never be any solutions to the system.
If they go up at the same rate, the lines would be parallel no matter the y-intercept. Because of this, it will NEVER intersect or give any solutions.
Answer:
x = 2, y = 3
Step-by-step explanation:
x - 3y = - 7 → (1)
x = 5 - y → (2)
Substitute x = 5 - y into (1)
5 - y - 3y = - 7
5 - 4y = - 7 ( subtract 5 from both sides )
- 4y = - 12 ( divide both sides by - 4 )
y = 3
Substitute y = 3 into (2)
x = 5 - 3 = 2
solution is (2, 3 )
Answer:
Surface area of the smaller pyramid will be 225 cm²
Step-by-step explanation:
Two similar pyramids have their matching or corresponding sides in the ratio of 5 : 7.
In other words,
=
Therefore, =
= 225 cm²
Therefore, surface area of the smaller pyramid will be 225 cm².
