Miley earns $10 per hour babysitting. Is the amount of money earned proportional to the number of hours she spends babysitting?

1 answer:

5 0

The amount of money she earns is proportional to the number of hours she babysits. For every 1 hour she babysits, she earns $10. If she babysits 2 hours, the pay is $20. It is a $10 to 1 hour rate(ratio).

Consider the function $f(x)=\sqrt{x}.$ This function has:

the domain $x\in [0,\infty);$
the range $y\in [0,\infty).$

If the domain of unknown function is $[a,\infty),$ then $x\ge a$ or $x-a\ge 0.$ This means that you have $\sqrt{x-a}$ as a part of needed function.

If the range of unknown function is $[b,\infty),$ then $y\ge b.$ This means that you have to translate function b units up and then the expression of the function is

$y=\sqrt{x-a}+b.$

Answer: correct choice is B.

PLEASE HELP I WILL BRAINLIST

PSYCHO15rus [73]

Answer:

Step-by-step explanation:

Since they intersect you can just solve for x and y

since y=-4x and y=x^2+2x+8, you can set -4x=x^2+2x+8

add 4x to both sides to make 0=x^2+6x+8

and factor out (x+4)(x+2)

so the solutions for x are -4 and -2

then insert the two values for x into the first equation

so y=-4(-4) and y=-4(-2)

so y=16 and y=8 when x=-4 and x=-2

so the smallest value for y in both equations is 8

Please give brainliest :)

There are 3x-2 trees planted in each row of a rectangular Parcel of land. If there are a total of 24x-16 trees planted and the p

m_a_m_a [10]

If one raw contains 3x-2 trees & if the total trees in the rectangle are 24x-16, that means Horizontal Rows x Vertical Rows =Total number of trees:

(3x-2) * Vertical Rows = 24x-16 ===> Vertical Rows =(24x-16) / (3x-2)

Perform the division & you will find Vertical Rows =8

two verticies of paralellogram ABCD are A(-6,-1) and B(-5,3). The intersection of the diagonals, E, are (-2, 1/2). Determine the

masya89 [10]

Answer:

D(2,2)

Step-by-step explanation:

The diagonals of a parallelogram gram bisects each other.

Therefore E is the midpoint of AD.

Let the coordinates of D be (a,b).

By the midpoint rule:

$( \frac{x_1+x_2}{2} ,\frac{y_1+y_2}{2}) = ( - 2, \frac{1}{2} )$
