Answer:
x = -5 and y = 3
Step-by-step explanation:
There are two equations :
3x − 2y = −21 ....(1)
2x + 5y = 5 ......(2)
Multiply equation (1) by 2 and equation (2) by 3.
6x - 4y = -42 ...(3)
6x + 15y = 15 ....(4)
Subtract equation (4) from (3) :
6x - 4y - (6x + 15y) = -42 -15
-4y -15y = -57
-19y = -57
y = 3
Put y = 3 in equation (2) :
2x + 5(3) = 5
2x = 5-15
2x = -10
x = -5
So, the value of x is (-5) and y = 3.
Answer:
<h3>15</h3>
Step-by-step explanation:
<h2>you need to find the lcf(least common factor) of the two numbers which is 15</h2>
Answer:
-4/2, or finding slope is (difference of y)/(difference of x) inserting those numbers into the equation would be (-5-(-1))/(2-0), which would become -4/2, which is basically -2.
Answer:
40+4.50x+112
16 shoes daily to make his goal
Step-by-step explanation:
to find how much shoes he would have to sell take away 40 from both sides of the equation which would leave you with 4.50x=72 next divide 4.50 out of both sides of the equation x=16 so he would have to sell 16 pairs of shoes a day to meet his goal
