IRINA_888 [86]

Answer:

Flora can make 10 pairs of socks and 5 pairs of gloves.

Step-by-step explanation:

Here we have to form two equations from the given information.

Let "x" be the number of pair of socks and "y" be the number of pair of gloves.

Given:

It takes flora 3 hours to knit a pair of socks and 7 hours to knit a pair of gloves. If she spent 65 hours knitting a total of 15 pairs of socks and gloves,

x + y = 15

3x + 7y = 65

Now we have to solve these two equations to find the solution.

Let's use the substitution method.

From the first equation can be written as

x = 15 - y

Now plug in x = 15 - y in the second equation and find the value of y.

3(15 - y) + 7y = 65 (This is called substitution method)

45 - 3y + 7y = 65

Simplify the like terms

45 + 4y = 65

Subtract 45 from both sides, we get

4y = 65 - 45

4y = 20

Dividing both sides by 4, we get

y = 20/4

y = 5

Now plug in y = 5 in the x = 15 - y

x = 15 - 5

x = 10

Therefore, Flora can make 10 pairs of socks and 5 pairs of gloves.

A function represented by the equation y=1/3x + 4 is a graph on a coordinate plane. What will happen to the line if the slope is

Stella [2.4K]

Answer:

Graph of the new function will be vertically stretched by 2 units.

Step-by-step explanation:

A linear function is represented by the equation, y = $\frac{1}{3}x+ 4$

This function has the slope = $\frac{1}{3}$ and y-intercept = 4

If this function is stretched vertically by 'k' the the equation of the new function will be,

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

y = $\frac{a}{3}x+4$ ---------(1)

If the slope of this equation is changed to $\frac{2}{3}$ ,

New equation of the function will be,

y = $\frac{2}{3}x+4$ ---------(2)

Comparing equations (1) and (2),

a = 2

Therefore, graph of the new function will be stretched vertically by 2 units.
