Y = -3x + 5
5x - 4y = -3
5x - 4(-3x + 5) = -3
5x + 4(3x) - 4(5) = -3
5x + 12x - 20 = -3
17x - 20 = -3
+ 20 + 20
17x = 17
17 17
x = 1
y = -3x + 5
y = -3(1) + 5
y = -3 + 5
y = 2
(x, y) = (1, 2)
Sinα=h/L where h=height, L=string length...
h=Lsinα so
h(25°)=50sin25≈21.1ft
h(45°)=50sin45≈35.4ft
Step-by-step explanation:
Triangular prisms have their own formula for finding surface area because they have two triangular faces opposite to each other. The formula A=12bh is used fo find the area of the top and bases triangular faces, where A=area, b=base, and h = height.
Answer:
x=21-5x4
x=21-20
x=1
Step-by-step explanation:
The correct choice is the final answer.
We want x to be greater than or equal to 4.3. The closed circle tells us that it can be equal to 4.3. The ray to the right tells us that we are looking for numbers larger than 4.3.
