Answer:
No, the answer is (-3/7, -33/7)
Step-by-step explanation:
y=-3x-6 can be rewritten as y+3x=-6
so, our two equations are:
1. y+3x=-6
2. 3y+2x=-15
we can multiply the first equation by 3.
1-1.3y+9x=-18
Now we can subtract the second equation from equation 1-1.
3y+9x=-18
<u>-(3y+2x=-15)</u>
7x=-3
x=-3/7
Now that we have x, let's plug it into an equation. I will plug it into the first equation.
y=-3(-3/7) - 6
y=9/7 - 6
y=-33/7
so the points are (-3/7, -33/7)
Answer:
Step-by-step explanation:
You have no grounds for making a statement like that. There are a variety of reasons why you might not get immediate answers. Be patient.
I will do the second part of this question (finding the first three numbers):
a(4) = a(3)*(-3) + 2 = -148, so a(3)*(-3) = -150 and a(3) = -50
a(3) = 50
a(2) = a(3)*(-3) + 2 = 50, so -3*a(3) = 48 and a(d) = -16
a(1) = a(2)*(-3) + 2 = -16, so a(2)*(-3) = -18 and a(1) = 6
The procedure for finding a(5), a(6) and a(7) is exactly the same.
Answer:
Step-by-step explanation:
<u>Use the formula:</u>
- degrees/360° = L/circumference
- or
- radians/π = L/circumference
<u>As per given:</u>
l = 12 feet, r = 10 feet
- degrees = 360°*12/(2*3.14*10) = 68.78°
- radians = π rad *12/(2π*10) = 0.6 rad
2(x+9)=7
If you wanted to simplify;
2x+18=7 (Distributive Property)
2x=-11 (Subtraction Property of Equality)
x=-11/2 (Division Property of Equality)
