Is the ordered pair (–8, –7) a solution to the equation 3x + 10 = 2y? Show your work.
Answers
Answer:
yes
Step-by-step explanation:
Substitute x = - 8 and y = - 7 into the equation
If both sides are equal then (- 8, - 7) is a solution
left side = 3x + 10 = 3(- 8) + 10 = - 24 + 10 = - 14
right side = 2y = 2(- 7) = - 14
Since both sides are equal then (- 8, - 7) is a solution to the equation
Final answer:
The ordered pair (-8, -7) is a solution to the equation 3x + 10 = 2y. This is determined by substituting the values of the ordered pair into the given equation leading to -14 on both sides of the equation.
Explanation:
To determine if the ordered pair (-8, -7) is a solution to the equation 3x + 10 = 2y, we can substitute -8 for x and -7 for y in the equation.
This would result in 3*(-8) + 10 = 2*(-7), which simplifies to -24 + 10 = -14. So the left side of the equation equals -14, and the right side of the equation equals -14 as well. Because both sides equal the same value, the ordered pair (-8, -7)is a solution to the given equation.

Answer:
0.012
Step-by-step explanation:
Linear approximation says that,
For a cube the surface area is .
So the side is 1.0 inch in, the surface area is square inches.
In Linear approximation means you ignore the term , if
is a small number, because then
will be a very smalle number and that does not contribute much to the error.
So the surface area is approximately,
So here,
The error in the area is approximately,
So the error is 0.012.
