Answer:
Step-by-step explanation:
So we have the equation:
To solve for k, subtract 4.1 from both sides:
The right cancels. Simplify the left:
Thus, the value of k is 5.2
Answer:
m= -5/8
Step-by-step explanation:
Slope of a line containing the points,
where, m is the slope
Here,
Franco:
3x+2y=19
Caryl:
2x+4y=24
now use elimination
-2(3x+2y=19)
1(2x+4y=24)
=
-6x-4y=-38
2x+4y=24
add them together
which equals -4x=-14
divide both sides by -4
-4x/-4=-14/-4
x=7/2
we found x, so we subsitute it into the the original equation
3x+2y=19
3(7/2)2y=19
2y+21/2=19
-21/2 -21/2
2y=17/2
divide by 2 on both sides
2y/2= 17/2/2
y=17/4
so x= 7/2 and y= 17/4
Answer:
it’s 15x+30y-220
Step-by-step explanation:
Because you distribute and then you add the like terms
You should really edit that to were there r diagrams
