Answer:
Below.
Step-by-step explanation:
You find the values of y by substituting the values of x in the expression x^2 + 3x - 1.
So f(-4) = (-4)^2 + 3(-4) - 1 = 16-12-1 = 3
in the same way f(-3) = -1, f(-2) = -3, f(-1) = -3,
f(0) = -1 and f(1) = 3.
Now plot the points (-4, 3) , (-3, -1) and so on
Then you can read the values off this graph.
Answer:
Step-by-step explanation:
By applying geometric mean theorem in the given right angle,
By substituting values in the given ratio,
Exact value of y is 
.
*The side with the middle length is 12cm, therefore BC must be 12 cm

BC:AC:AB
4 : 3 : 5
</span>-----------------------------------------------------------
<span>Find 1 share
</span>-----------------------------------------------------------<span>
Given that BC = 12 cm
4 shares = 12 cm
1 share = 12 ÷ 4 = 3cm
</span>-----------------------------------------------------------
Find AC (4 shares)
-----------------------------------------------------------<span>
3 shares = 3 x 3 = 9 cm
BC = 9cm
</span>-----------------------------------------------------------
<span>Find AB (5 shares)
</span>-----------------------------------------------------------<span>
5 shares = 5 x 3 = 15cm
AB = 15cm

Given that the biggest ratio is AB
</span>⇒AB is the hypotenuse
AB = 15 cm

Answer: 8^2 18^2
Step-by-step explanation: The way that you figure out the power is by multiplying the 4x2=8 than the 9x2=18 than you raise them both to the second power.
