<span>4x + 3y = 16
7x + 6y = 31
Note what happens if we mult. the first eqn. by -2:
-8x - 6y = -32
Combining this with the 2nd equation eliminates the variable y:
</span>-8x - 6y = -32<span>
7x + 6y = 31
--------------------
-x = -1, or x = 1. Sub 1 for x in either of the 2 given eqns to find y:
For example: 4(1) + 3y = 16, so 36 = 12, and y = 3. Sol'n is (1,3).</span>
Answer:
(C - B)/A = x
Step-by-step explanation:
Ax + B = C
-B -B
Ax = C - B
Divide both sides by A
x = (C - B)/A
(C - B)/A = x
Answer:
numbers less than 5 are 1,2,3,4 and equal to 5 is 5.
probability of less than 5 is 4/16
while equal to 5 is 1/16
or means additions; so its 4/16 +1/16=5/16
The answer is (A) c = 0 or c = 4.
Answer:
A) y-4=2/5(x+2)
Step-by-step explanation:
passes through (-2,4) and has a slope of 2/5
y - 4 = 2/5(x + 2)
