Look at the graph below:
which part of the graph best represents the solution set to the system of inequalities y ≥ x + 1 and y + x ≥ −1?
sundar multiplied the second equation by -9.
we are given two linear equations and we know that sundar multiplied the first equation by 5 and the second equation by another number to eliminate the y-terms.
we are to find that another number.
2x+9y = 41 (1)
multiplying the first equation by 5 we get:
10x + 45y = 205 (3)
since we have to eliminate the y terms so coefficients of y must be the same but with opposite signs. so we need -45y in the second equation to eliminate it.
for this, we need to multiply the second equation by -9 to get:
-27x - 45y = -324
each weighs about 0.25kg
this is because since 15 oranges = 3.75, you should do 3.75 / 15 which gets you 0.25.
