kicyunya [14]3 years ago
4 0

Answer:

1. is 7 to 1 and

2. is 3 to 6

Step-by-step explanation:

You get number one's answer by finding to difference between 13 to 7 which Is six. so now you start at 1 and add 6 which would be 7 and would give you your answer of 7 to 1.

You get number two's answer by finding the ratio given which is 1 black square to 2 Grey squares. Since it mentions to triple it you multiply both numbers by 3. which would give you 3 to 6. You know that this is right because it is equivalent to 1/2 which was what the first ratio was.

you're welcome

Y + 4/9 = 2/3 Solve the equation..
emmainna [20.7K]
Y + 4/9 = 2/3

Let's convert 2/3 into 6/9 so it will be easier to subtract.

Y + 4/9 = 6/9
Subtract 4/9 on both sides.

Y = 2/9 Hope this helps!

Determine whether LINE AB and LINE CD are parallel, perpendicular, or neither. A(−1, −4) , B(2, 11) , C(1, 1) , D(4, 10) ( write
Luba_88 [7]

Step-by-step explanation:

Hey there!

The points of line AB are; (-1,-4) and (2,11).

Note:

  • Use double point formula and simplify it to get two eqaution.
  • Use condition of parallel lines, perpendicular lines to know whether the lines are parallel or perpendicular or nothing.

~ Use double point formula.

(y - y1) =  \frac{y2 - y1}{x2 - x1} (x - x1)

~ Keep all values.

(y  + 4) =  \frac{11 + 4}{2 + 1} (x + 1)

~ Simplify it.

y + 4 =  \frac{15}{3} (x + 1)

y + 4 = 5x + 5

5x - y + 1 = 0

Therefore this is the equation of line AB.

Now, Finding the equation of line CD.

Given;

The points of line CD are; (1,1) and (4,10).

~ Using formula.

(y - y1) =  \frac{y2 - y1}{x2 - x1}(x - x1)

~ Keep all values.

(y - 1) =  \frac{10 - 1}{4 - 1} (x - 1)

~ Simplify it.

y - 1 = 3 x - 3

3x - y - 2 = 0

Therefore, 3x - y- 2 = 0 is the eqaution of line CD.

Use condition of parallel lines.

m1= m2

Slope of equation (i)

m1 =  \frac{ - coeff. \: of \: x}{coeff \: of \: y}

m1 =  \frac{ - 5}{ - 1}

Therefore, m1 = 5

Slope of second equation.

m2 =  \frac{ - coeff \: .of \: x}{coeff \: .of \: y}

m2 =   \frac{ - 3}{ - 1}

Therefore, m2 = 3.

Now, m1≠m2.

So, the lies are not parallel.

Check for perpendicular.

m1*m2= -1

3*5≠-1.

Therefore, they aren't perpendicular too.

So, they are neither.
