Use the substitution method to solve the system of equations

Mathematics
1 answer:
yarga [219]2 years ago
5 0

Answer:

C. (3,2)

Step-by-step explanation:

to begin the substitution method, we can begin by substituting the answer choice value into the given system or equations to determine if the values make the equation true.

the first choice is (2,1)

3(2) + 2(1) = 13

6 + 2 is not equal to 13. Therefore this answer choice is incorrect.

second choice (1,2)

3(1) + 2(2) = 13

3 + 4 is not equal to 13. This answer is also incorrect.

third choice (3,2)

3(3) + 2(2)

9 + 4 = 13 is true!

we can also substitute these x and y values for the equation underneath:

y = x - 1

2 = 3 - 1

2 = 2 is true! Therefore, C. (3,2) is correct!

If you raise 4 to the 214th power, what is the units digit of the result
Len [333]
\begin{array}{lrlll}
4^1&\boxed{4}\\
4^2&1\boxed{6}\\
4^3&6\boxed{4}\\
4^4&25\boxed{6}\\
4^5&102\boxed{4}\\
4^6&409\boxed{6}
\end{array}\impliedby \textit{see the pattern for 4?}

notice, it goes 4,6 then 4, 6 again, and so on and so on
based on whatever exponent it may have

now, you're being asked, what 214 will give? 4 or 6?

solve image :) What is the equation of the line that has a slope of 3 and passes through the point (-4, 1)?
Lesechka [4]

Answer:

<em>C.  y = 3x + 13.</em>

Step-by-step explanation:

The point slope form of a line is

y - y1 = m(x - x1)  where m = the slope,  and (x1, y1) is a point on the line.

So, substituting:

y - 1 = 3(x - -4)

y - 1 = 3(x + 4)

y = 3x + 12 + 1

y = 3x + 13.
