Answer:
Step-by-step explanation:
-6x + 3y = -7
to find the x intercept, sub in 0 for y and solve for x
-6x + 3y = -7
-6x + 3(0) = -7
-6x = -7
x = 7/6 <=== ur x intercept is (7/6,0)
to find the y intercept, sub in 0 for x and solve for y
-6x + 3y = -7
-6(0) + 3y = -7
3y = -7
y = -7/3 <=== ur y intercept is (0,-7/3)
4/24 because you mutually 1 by 4 and get 4 and 6 by 4 and get 24
Answer:
2c -2 = Steve's age 2 years ago
Step-by-step explanation:
2x+4y=0
substitute y with 0
2x+4(0)=0
solve the equation
2x+0=0
2x=0
divide by 2 on both sides
x=0
4x+8y=7
substitute y with 0
4x+8(0)=7
solve the equation
4x+0=7
4x=7
divide by 4 on both sides
x=7/4 or x=1 3/4 or x=1.75
3x-7y=-29
2x+2y=6
solve the bottom equation
3x-7y=-29
x=3-y
substitute for x
3(3-y)-7y=-29
solve the equation
y=19/5
now substitute for y
x=3-
solve for x
x=-4/5
the possible solution of the system is the ordered pair
(x,y)=(
)
Answer:
y=x+8
Step-by-step explanation:
y=x+b
That is the equation with only the slope, however, we can use the point (-4,4) to find the y-intercept
4=-4+b
Add 4 both sides:
8=b
Thus the equation is y=x+8
Hope this helps!
