some large frames for $14 each and some small frames for $4 each at a closeout sale. If she bought 16 frames for $114, find how

Gnoma [55]

Answer:

11 small frames, 5 large frames

Step-by-step explanation:

small: x

large : y

x + y = 16

4x + 14y = 114

Multiply first equation by 4 and subtract.

4x + 4y = 64

-(4x + 14y = 114)

-10y = -50

y = 5

Substitute y into the first equation.

x + 5 = 16

x = 11

Find the equation of the straight line through (3,4) and (5,6).

Viktor [21]

Answer:

y= x+1

Step-by-step explanation:

The equation of a line is usually written in the form of y=mx+c, where m is the gradient and c is the y-intercept.

Gradient of line = $\frac{y1 - y2}{x1 - x2}$

Using the above formula,

Gradient

$= \frac{6 - 4}{5 - 3} \\ = \frac{2}{2} \\ = 1$

Thus m=1. Substitute m=1 into the equation:

y= 1x +c

y= x +c

Susbt. a coordinate.

When x=3, y=4,

4= 3 +c

c= 4-3

c=1

Thus, the equation of the line is y= x+1.
