Answer:
Since the lines are Perpendicular..
The Product of their Gradients = -1
m'm"=-1
m' from y=3x - 5 is 3
3.m" = -1
m" = -1/3.
Since Intercept on y axis = -2...
That of x at that point is =0
y-y' = m"(x-x")
y-(-2) = -1/3( x - 0)
y+2 = -1/3(x)
Multiplying through by 3
3y + 6 = -x
3y + x = -6. This is your Equation
To verify this.
Let's turn it into the Intercept form which is
x/a + y/b = 1
To get 1 at the right hand side... Divide through by -6
3y/-6 + x/-6 = 1
y/-2 - x/6 = 1
You could see directly below y is its intercept and thats -2
Answer:
Step-by-step explanation:
the answer is 16.8
Explanation: well for starters you have to do what's in the parenthesis, so 4 times 1.4 is equal to 5.6. so now we add up the equation and get 28, so now we are left with 28-5.6-5.6 which equals 16.8
hoped this helped;)
Ok um so I don't know if there are answer choices or not but if this is not the answer, im sorry. I would say that it would be 1.
Answer: 1
Explanation: I say one because your going to the left of three so your subtracting instead of adding because if it said to the right, then you would add.
Weight of baby boy , w = 7 lb 8 oz .
Weight of 5 year kid , W = 48 lb .
We know , 16 oz = 1 lb .
So , w = 7 + 0.5 = 7.5 lb .
Now , ratio is :
Therefore , the ratio of the baby's weight to the boys weight as a fraction is
.
Hence , this is the required solution .
3(2x-3)+4(2-x)=0
6x+9+8-4x=0
2x+17=0
2x=-17
x=-17/2
The answer is C.
