Solve the following system of equations for x and y.
1 answer:
<h2>Answer:</h2>
We can solve this system by elimination to solve for y by multiplying the top equation by 4 and the bottom one by -5.
Now, with what we got for y, we plug it back into one of the original equations. I chose the top one.
Now we have the solution of this system
The solution is <em>A. (-1, -3)</em>.

Answer: 29/28
Step-by-step explanation:
To add fractions we have to calculate the Least Common Denominator of the denominators. Then we have to change each fraction (using equivalent fractions) to make their denominators the same as the Least Common Denominator. Then we can add (or subtract) the fractions.
LCD (4,7,2)= 4·7 = 28
1/4 = 7/28
2/7 = 4·2/28 = 8/28
1/2 = 14/28
Since the fractions have the same denominator we can add them
7/28 + 8/28 + 14/28 = (7+8+14)/28 = 29/28
Answer:
a. What is the slope of the line?
b. What is the x-intercept of the line? (Where does the line cross the x-axis?)
