How to solve 9 and 10?

Mathematics
1 answer:
netineya [11]3 years ago
4 0

Answer:

Step-by-step explanation:

Simply, substitute the coordinates (x,y), in the equation given!

9. 5 = 3(-3)/4 -4

   5 = -9/4 -4

   5 = -25/4

The LHS is not equal to RHS, this means that the given coordinate doesn't exist on the linear function given!

10.  5(10)-6(7) =18

      50-42 =18

              8=18

Same as above, it doesn't work!

Hope this helps!

On a coordinate plane, a line is drawn from point A to point B. Point A is at (2, negative 3) and point B is at (negative 4, 9).

Answer: (0,1)

Step-by-step explanation:

If (x_1, y_1) and  (x_2, y_2) are two point son a coordinate plane and (x,y) dividing it in a ratio of m: n.

Then , the coordinates of (x,y) is given by :-

x=\dfrac{nx_1+mx_2}{m+n}

y=\dfrac{ny_1+my_2}{m+n}

Given : On a coordinate plane, a line is drawn from point A to point B. Point A is at (2, - 3) and point B is at (- 4, 9).

Then , the x- and y- coordinates of point E, which partitions the directed line segment from A to B into a ratio of 1:2 :

x=\dfrac{2(2)+1(-4)}{1+2}=0

y=\dfrac{2(-3)+1(9)}{1+2=1}

Hence, the x- and y- coordinates of point E = (0,1)

Answer:

5%

Step-by-step explanation:

Multiply both numerator and denominator by 100. We do this to find an equivalent fraction having 100 as the denominator.

0.05 × 100/100

= (0.05 × 100) × 1/100 = 5/100
