Answer:
y=2x-1
Step-by-step explanation:
y=mx+b
insert Point (0,-1)
-1 = m * 0 + b
-1 = b
slope:
m = delta y / delta x
m = 2 / 1
m = 2
The perimeter is 56m
H = 4m
Base area = 96m^2
96/4 = 24
Therefore the length is 24m
4m + 24 = 28m
multiplied by 2 is equal to 56m.
Answer:
The answer is D
Step-by-step explanation:
Answer:
B. 36 square units
Step-by-step explanation:
This is a triangle and to calculate the area of a triangle we multiply height with base and that divided by two
The height of this triangle is 8 units and the base is 9 units
9 × 8 ÷ 2 = 36 square units
x - y = 16
x^2 + x^2 = 130
----------------
x^2 - y^2 = 256
+(x^2 + y^2 = 130)
2x^2 = 386
x^2 = 193
x = <span>13.892 (3DP)
----
</span>x - y = 16
13.892 - y = 16
-y = 2.108
y = -2.108
The numbers are: 13.892 and -2.108
