Answer:
(x,y) (1,-1)
Step-by-step explanation:
y=3-4x
-x+2y=-3
x+2(3-4x)=-3
x=1
y=3-4*1
y=-1
Answer: Assume c = 0
Step-by-step explanation:
Step-by-step explanation:
Assume c = 0
Using the formula for the x-coordinate of the vertex, b can be calculated in terms of a:
B can then be substituted into the quadratic equation, along with the coordinates of the vertex, to solve a:
AND
Substituting into the quadratic equation:
Because a is negative, the parabola opens up.
The French had many alliances with the Indians and the British had more troops. The French has to deal with untrained troops.

Answer:
a = 23
b = 10
Step-by-step explanation:
The general formula is
y = 3x + 5
Just to check, let x = 2
y = 3*2 + 5
y = 6 + 5
y = 11
And a confirmation check
x = 3
y = 3*3 + 5
y = 9 + 5
y = 14
So for a
x = 6
y = 6*3 + 5
y = 18 + 5
y = 23
For b, you know y
35 = 3x + 5
<u>- 5 -5 </u> Subtract
30 = 3x Divide by 3
30/3 = 3x/3
x = 10
Answer:
6 x 3 = 18, 18 x 2 = 36
9 x 3 = 27, 27 x 2 = 54
6 x 9 = 54, 54 x 2 = 108
Add all given areas:
108 + 54 + 36 = 198 cm^2 is your answer.
