Answer:
{d,b}={4,3}
Step-by-step explanation:
[1] 11d + 17b = 95
[2] d + b = 7
Graphic Representation of the Equations :
17b + 11d = 95 b + d = 7
Solve by Substitution :
// Solve equation [2] for the variable b
[2] b = -d + 7
// Plug this in for variable b in equation [1]
[1] 11d + 17•(-d +7) = 95
[1] -6d = -24
// Solve equation [1] for the variable d
[1] 6d = 24
[1] d = 4
// By now we know this much :
d = 4
b = -d+7
// Use the d value to solve for b
b = -(4)+7 = 3
Solution :
{d,b} = {4,3}
Answer:
y=3/2x+7
Step-by-step explanation:
y=mx+b
m=3/2
b=7
Answer:
y=-6x-24
Step-by-step explanation:
just expand
y+6=-6x-18
then move the six from the left to the right
y=-6x-24
Answer:
For the first picture: the answers A
For the second picture: it is also A
Step-by-step explanation:
I put each fraction into desmos for the second picture and the one that matched the image was A.
For the first image i picked A because 10 is a constant without a variable and is not a coefficient.
