Answer:

C. y=-3x+2

Step-by-step explanation:

Looking at the graph, we see that the line intercepts the y axis at 2 and is decreasing as x increases.

The formula for a linear equation is y=mx+b

where b is the y intercept, which in this case is 2

since the y values decreases as x increases, m must be negative

Answer:

Step-by-step explanation:

$\bigg( \frac{16}{49} \bigg)^{ - \frac{3}{2} } \\ \\ = \bigg( \frac{49}{16} \bigg)^{ \frac{3}{2} } \\ \\ = \bigg( \frac{ {7}^{2} }{ {4}^{2} } \bigg)^{ \frac{3}{2} } \\ \\ = \bigg( \frac{ {7}}{ {4} } \bigg)^{ \frac{2 \times 3}{2} } \\ \\ = \bigg( \frac{ {7}}{ {4} } \bigg)^{ 3} \\ \\ = \frac{343}{64} \\$

Can anybody help me with this

kondaur [170]

Answer:

c ≈ 9.1 m

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides , that is

c² = 4.1² + 8.1² = 16.81 + 65.61 = 82.42 ( take square root of both sides )

c = $\sqrt{82.42 }$ ≈ 9.1 m ( to the nearest tenth )

Can someone help please

Alik [6]

Answer:

Step-by-step explanation:

base + 2(legs) = 56 (2 legs are the same because it's isosceles)

x + 2(5x - 5) = 56

x + 10x - 10 = 56

11x -10 = 56

11x = 66

x = 6
