Find the value of the variable if P is between J & K. JP = 3y+1 ; PK = 12y - 4 ; JK = 75

1 answer:

3 0

JP + PK = JK
3y + 1 + 12y - 4 = 75
15y -3 = 75
15y = 75 +3
15y = 78
y = 78/15
y = 5.2

answer is a. 5.2

May someone please help me out with this problem? May you also explain it?

gavmur [86]

Answer:

Step-by-step explanation:

Given function is,

f(x) = $\sqrt{x}$

If the given function is vertically stretched by a scale factor of $\frac{3}{2}$ Or 1.5,

Transformed function will be,

h(x) = $\frac{3}{2}[f(x)]$

h(x) = $\frac{3}{2}(\sqrt{x})$

Further function 'h' is shifted 1 units upwards,

g(x) = h(x) + 1

g(x) = $\frac{3}{2}(\sqrt{x} )+1$

Domain of the function → x ≥ 0 Or [0, ∞)

Range of the function → y ≥ 1 Or [1, ∞)

Transformations done → Parent function f(x) is vertically stretched by a scale factor of $\frac{3}{2}$ then shifted 1 unit upward.

Y= 4/5 x-7 what are the y and x intercepts?

solmaris [256]

The x intercept is (8.75, 0) and y - intercept is (0, -7)

Solution:

Given that we have to find the x and y intercepts

Given equation is:

$y = \frac{4}{5}x - 7$

The x intercept is the point where the line crosses the x axis

The y intercept is the point where the line crosses the y axis

Finding x - intercept:

To find the x-intercept of a given equation, plug in 0 for 'y' and solve for 'x'

Substitute y = 0 in given equation

$0 = \frac{4}{5}x - 7\\\\\frac{4x}{5} = 7\\\\4x = 35\\\\x = \frac{35}{4} = 8.75$

Thus x intercept is (8.75, 0)

Finding y - intercept:

To find the y-intercept, plug 0 in for 'x' and solve for 'y'

Substitute x = 0 in given equation

$y = \frac{4}{5} \times 0 - 7\\\\y = 0 - 7\\\\y = -7$

Thus y - intercept is (0, -7)

Yupin is making fruit punch. The recipe calls for 2 ½ of guava juice. The guava juice container has 4 ¼ cups of juice in it. How

astraxan [27]

Answer:

1 $\frac{3}{4}$ cups

Step-by-step explanation:

Convert the numbers to decimals, then subtract the amount needed from the amount in the juice container:

4.25 - 2.5

= 1.75

This is equivalent to the fraction 1 $\frac{3}{4}$

So, after Yupin makes the punch, there will be 1 $\frac{3}{4}$ cups of guava juice left in the container
