Answer:
x = 16
Step-by-step explanation:
G is equal 12.3 in this equation
Answer:
X= 2/5 y=-2
Step-by-step explanation:
5x + 2y = -2
3x - 5y = 11.2
Using the elimination method
Multiply equation 1 by 3
Multiply equation 2 by 5
15x + 6y = -6
15x - 25y = 56
Subtrat 3 from 4
-31y= 62
Divide both sides by -31
y= -2
To arrive at x, substitute y= -2 in equation 1
5x + 2y = -2
5x + 2(-2)= -2
5x -4 = -2
Collect like terms
5x= -2+4
5x= 2
Divide both sides by 5
x= 2/5
Answer:
The value of a=6[/tex]
Step-by-step explanation:
<u>step 1:- </u>
<u>col linearity of three points :- </u>
We know that slopes of two parallel lines are equal.If two lines having the same slope pass through a common point ,then two lines will coincide . Hence ,If A,B,C are three points in the X Y- plane, then they will lie on a line,
that is three points are col linear if and only if Slope of AB= slope of BC
<u>step 2:-</u>
Since the given three points are col-linear, we have
Slope of AB= slope of BC
given points are A(2,-2) ,B(-6,2) and C(a,-4)
<u>Step 3 :-</u>
Slope of AB= slope of BC

Answer: B
Step-by-step explanation:
The second power basically means that you multiply the number by itself that many times depending on the power, and since it's 50^2, the answer is Caleb - 100 | Jenna - 2,500. (Tip: Just multiply 50 x 50)
