<span>1 x + 1 y = 7 .............1
Total value
15 x + 28 y = 131 .............2
Eliminate y
multiply (1)by -28
Multiply (2) by 1
-28 x -28 y = -196
15 x + 28 y = 131
Add the two equations
-13 x = -65
/ -13
x = 5
plug value of x in (1)
1 x + 1 y = 7
5 + y = 7
y = 7 -5
y = 2
y = 2
x= 5 plain shirts
y= 2 fancy shirts </span>
Answer:
y = -4
Step-by-step explanation:
This is because any point on that line would have a y coordinate of -4 → e.g. (6, -4), (-2, -4), and it intercepts the y axis at -4.
Hope this helps!
Answer:
b=3
Step-by-step explanation:
48/6-5=b
you are solving for b
always do problems in this order:
parentheses
exponents
multiply
divide
add
subtract
this problem only has
divide and subtract
so you will divide first
48/6= 8
then you will subtract
8-5=3
so b=3
ANSWER
D) (a + 1, b + m)
EXPLANATION
The given line passes through (a,b) and has slope m.
The equation is:

When x=a+1, we obtain

This


Therefore,(a + 1, b + m) must also lie on this line.
The correct answer is D.
