Answer:
((2a+b)/2 , a/2)
Step-by-step explanation:
The midpoint is the mean/average of both the x and y values.
Our x values are a+b and a
Our y values are a-b and b
The midpoint x value is (a+b + a ) /2 = (2a + b)/2
The midpoint y value is (a-b + b) /2 = (a)/2
The midpoint combines these two values to get ((2a+b)/2 , a/2) as our midpoint
Answer:
Odd
Step-by-step explanation:
Answer:
Step-by-step explanation:
Adding the two equations together gives you
9x-10y-9x-6y=145+15
-16y=160
y=-10, using this value in 9x-10y=145 gives you
9x-10(-10)=145
9x+100=145
9x=45
x=5
So y=-10 and x=5
Answer:
The value of x is 500
Step-by-step explanation:
Given as :
log20x³ - 2 logx = 4
<u>From log property </u>
So , log20x³ - logx² = 4
<u>Again From log property </u>
log m- log n = log
So, log20x³ - logx² = ![log\frac{20x^{3}}{x^{2}}](https://tex.z-dn.net/?f=log%5Cfrac%7B20x%5E%7B3%7D%7D%7Bx%5E%7B2%7D%7D)
Or,
= 4
So
=
( antilog property)
Or, 20 x = 10000
∴ x = 500
Hence The value of x is 500 Answer
Answer:
x > -1/2
Step-by-step explanation:
Step 1: Use the Distributive Property
-2x - 1 < 0
Step 2: Isolate x
-2x < 1
Step 3: Simplify
x > -1/2
Note that when dividing by a negative in an inequality, reverse the inequality symbol.
