Answer:
The answer is C
Step-by-step explanation:
117 + 23 =140 and you have $140 in all so you spent it all
The value of the constant a will the system of linear equations 6x-5y=3 and 3x+ay=1 have no solution is -5/2
<h3>System of equation</h3>
For a system of equation to have no solution, the expression on both sides must be different.
Given the system of equation
6x-5y=3 and
3x+ay=1
For the equations to have no solution, the a1/a2= b1/b2
Substitute
6/3 = -5/a
Cross multiply
2 = -5/a
a= -5/2
Hence the value of the constant a will the system of linear equations 6x-5y=3 and 3x+ay=1 have no solution is -5/2

You will have to use the formula y-y1=m(x-x1)
Use the coordinates of the given point to fill in y1 and y2 and use the given slope as m.
Then if it is desired for the final equation to be solved for y (slope intercept form) just factor the one side, and solve for y
EXAMPLE: given slope=3 given point that the line passes through= (5,7)
y-y1=m(x-x1)
y-7=3(x-5)
y-7=3x-15
y=3x-15+7
y=3x-8
Answer:
B (-1, 1.5)
Step-by-step explanation:
Add the x coordinates together and divide by 2: (-4 + 2) = -2/2 = -1.
The only option with (-1) as an x-coordinate is B, and that is the answer.
