Answer:

$\frac{1}{3}\ of\ Rs.30 = Rs.10$

Step-by-step explanation:

Given

$\frac{1}{3}\ of\ Rs.30$

Required

Solve

of means *. So, we have:

$\frac{1}{3}\ of\ Rs.30 = \frac{1}{3}\ *\ Rs.30$

$\frac{1}{3}\ of\ Rs.30 = \frac{1\ *\ Rs.30}{3}$

$\frac{1}{3}\ of\ Rs.30 = \frac{Rs.30}{3}$

$\frac{1}{3}\ of\ Rs.30 = Rs.10$

Y=-|x+3| domain and range

Serjik [45]

Answer:

the domain is that x is a set of real numbers.

the range is y ≤ -3

Step-by-step explanation:

y = -|x + 3|

y is either positive or equal to zero.

Now, x is all real numbers because any value of x used will yield a valid value of y.

Thus, we can say that the domain is that x is a set of real numbers.

Now, for the range:

The minus sign in front of the absolute value indicates that the function has a maximum value.

Thus, the range is y ≤ -3

Batteries come in packs of 4. Last month, Joe used 58 batteries in his remote control drone. How many packs of batteries did he

vovangra [49]

It is given that batteries come in a packs of 4. It means in each pack there are 4 batteries.

Joe used 58 batteries . So to find the total number of packets of batteries joe has to open is

Number of batteries used / Total number of batteries in each packet

= 58 / 4

= 14.5

The number of battery can not be in decimal. So we will round the answer to integer. If we round it to 14 it means 14 packets. But in 14 packets there are 14*4 = 56 batteries .

But we know that Joe used 58 batteries. So we will round the final answer to 15.

It means Joe has to open 15 packets of batteries.

27. the y intercept is 2

28. the y intercept is -3

29. I cant answer because it is cut off in the picture...

Step-by-step explanation:

These equations follow a simple formula- the slope formula

y=mx+b

In this formula:

b is the y intercept

m is the slope that is multiplied by x

Need help with problems 16 and 17, please? I'll do brainiac

Answer: 16) y=-0.5x+3 and 17) y=2x-3

Step-by-step explanation:

16: The slope-intercept form of a line is y=mx+b, where m is the slope, and b is the y-value at the y-intercept.

Since y=3 at x=0, the y-intercept is (0,3), and b=3.

Slope= $\frac{y_{2} -y_{1} }{x_{2}-x_{1} }$ where ( $x_{1} ,y_{1}$ ) and ( $x_{2} ,y_{2}$ ) are two points on the line. Choose (0,3) and (2,2):

Slope= $\frac{2-3}{2-0}$ =-0.5

Plug m=-0.5 and b=3 into y=mx+b:

y=-0.5x+3

17: The slope-intercept form of a line is y=mx+b, where m is the slope, and b is the y-value at the y-intercept.

Because y=-3 at x=0, the y-intercept is (0,-3), and b=-3.

Slope= $\frac{y_{2} -y_{1} }{x_{2}-x_{1} }$ where ( $x_{1} ,y_{1}$ ) and ( $x_{2} ,y_{2}$ ) are two points on the line. Choose (0,-3) and (1,-1):

Slope= $\frac{-3-(-1)}{0-1}$ = $\frac{-2}{-1}$ =2

Plug m=2 and b=-3 into y=mx+b:

y=2x-3
