Solution: The given equation is →3 x+ 5 x=10
As you can see in the above equation on left side of equation the two terms are variables and on right side of equation the term is a constant term.Also you can see there is an operation called addition between the two variables on left side of equation.
In option (A), there is only a single term on right as well as left,so this can't be true.
In option (B), there is a constant and variable on left side of equation.So this is also untrue.
In option (C), variable being divided by numerator, so this is also untrue.
Option (D)3 x - 2 x = 10, is surely correct , because there are two variables on left side of equation and one constant on right side of equation, and there is an operation called subtraction between them .
Answer:
slope = - 
Step-by-step explanation:
Differentiating implicitly with respect to x
2x + 2y 
= 0
2y = - 2x
= - 
= - 
is the measure of the slope of the tangent
rearrange equation to find corresponding y-coordinate of x = - 2
y² = 16 - 4 = 12 = 2
⇒ y = ± 2
using x = - 2, y = - 2, then
= - 
= -
Answer:
First mechanic worked 20 hours and second mechanic worked 5 hours
Step-by-step explanation:
Let the number of hours the first mechanic worked = 
Let the number of hours the second mechanic worked = 
Therefore, we can write 2 equations and then solve them simultaneously:
Rearranging the first equation: 
and substituting into the second equation to find :
Now sub 
into the first equation to find
Therefore, first mechanic (a) worked 20 hours and second mechanic (b) worked 5 hours
Answer:
<em><u>5</u></em>
Step-by-step explanation:
They do not have the common factor of x or y, so not them.
The GCF is 5, Both numbers can be divded by 5:
20x/5 = 4x
35y/5 = 7y
Step-by-step explanation:
Just do this
