Answer:
The method used is substitution method
x = 2, y = -6
Step-by-step explanation:
Given the simultaneous equation
Y = −3x ..... 1
4x + y = 2 ... 2
Substitute equation 1 into 2
4x + (-3x) = 2
4x - 3x = 2
x = 2
Get y:
y = -3x
y = -3(2)
y = -6
<em>Hence the value of (x, y) is (2, -6)</em>

Answer can be wrote in two ways. -2.5a-5/6b or -5a/2-5b/6
Use product rule: x^a x^b = x^a + b
a^5 + 4 - 2
Simplify 5 + 4 - 2 to 7
Answer: a^7
Answer:
Step-by-step explanation:
Answer:
Step-by-step explanation:
This is a geometric progression.
Givens
a1 = 7
r = 6
Formula
a_n = a1 * r^(n - 1)
a_n = 7 (6)^(n - 1)
Sample
Try n = 3
a_3 = 7*(6)^(3-1)
a_3 = 7*(6)^2
a_3 = 7 * 36
.a_3 = 252 which is exactly what it should be.
