Ugh it is im confused just reading it
Answer:
Step-by-step explanation:
The answers are F,A,
Answer:
x= 1
y= -2
Step-by-step explanation:
equation (1): y= -3x+1
equation (2): y=x-3
solve the system of equations by substitution:
step1: sub ( x-3 ) for y in equation 1:
y = -3x+1
x-3 = -3x+1
step2: simplify the equation to get x:
(add 3 for both sides)
x = -3x+4
(add 3x for both sides)
4x = 4
(divide 4 from both sides)
x = 1
step3: sub the value of x (x=1) in equation 2:
y = x-3
y = 1-3
step4: solve the equation to get y:
y = -2
Answer:
Step-by-step explanation:
The equation is in slope-intercept form so y = mx + b, so whatever number is in front of the x (called a coefficient) is your slope, in this case 3/4
Direct variation has the form y=kx. Given a point we can solve for the constant k.
y=kx, when y=9 and x=-3 becomes:
9=-3k
k=-3 so the constant of variation is negative 3
