Answer:

200 blinks because if you 2.5 times 4 it equals 10

Answer:

y = 4

Step-by-step explanation:

y ∝ x

y = kx (k is constant)

when y = 12 and x = 3

y = kx

=> 12 = k*3

∴ k = 4

when x = 1 and k = 4

y = kx

  = 4*1

   = 4

Step-by-step explanation:

Distance formula: (see attached file) pythogorean rule

is the squared coordinates x added to squared coordinates of y

X- coordinates: -5 & -9

Y- coordinates: -5 & -2

Substitute into equation:

[tex]distance = \sqrt{ ( - 5- - 9)^{2} + ( - 5 - - 2)^{2} } = 5[/tex]

Answer:

119.38

Step-by-step explanation:

955÷8=119.375

=119.38

Answer:

Step-by-step explanation:

a.Changing f with -f does not change its domain, it just flips the image across the x axis. Adding 6 to the result, just shifts everything towards the positive y by 6 units. Domains stays the same, from -4 to +8. Range instead goes up, the lowest value is -2+6 = 4 and the highest value is 2+6 = 8.

So domain remains the same [-4; 8] and range goes to [4;8]

a. This time we're shifting everything on the horizontal axis, one unit to the left (the way to remember it is that f(x) has a minimum at x=4, while after the shift the new value happens at x=3) multiplying the value by 3 means that every value gets scaled up. It means the minimum becomes -2*3= -6 and the maximum happens at 2*3= 6. The shift brings the domain to [-5;7] and the range to [-6,6]

Answer:

260 Downloads

Step-by-step explanation:

s = number of standard downloads

3s = number of high-quality downloads

2.9s + 4.6(3s) = 4342

2.9s + 13.8s = 4342

16.7s = 4342

s = 260

The standard version was downloaded 260 times and the high-quality version was downloaded 780 times.

Answer:

Acute angle

Step-by-step explanation:

45°= Acute Angle

‘Cause It's less than 90°

Answer:

Step-by-step explanation:

It's an acute angle. Acute, in this case, means anything between 0 and 90 written 0<x<90. Notice that you are using < and not ≤. The endpoints are not included. They have their own names. 90 is a right angle. 0 is called a zero degree angle.

The percent of change in the price of a cellphone from 2010

to today is 58.33%

The price of cellphone was $240 in 2010.

While the price of cellphone presently is $380.

The percent of change in the price of a cellphone from 2010  to today is:

Percent change in price = [(380 - 240)/240] * 100%

Percent change in price = 58.33%

Hence, The percent of change in the price of a cellphone from 2010

to today is 58.33%

2.64m

Step-by-step explanation:

A rectangular table is measured to be 264 centimetres long and 1.55 metres wide.Convert the length of the rectangular table to metres. Write your answer as a decimal.

100cm = 1m

so

264cm = 2.64m

Answer:

you can write the equation of any line in the form of y = mx + b .

Step-by-step explanation:

Answer:

[tex]y = - \frac{1}{6} x + 2[/tex]

Step-by-step explanation:

Slope-intercept form

y= mx +c, where m is the slope and c is the y-intercept.

Let's first identify the coordinates of two points on the graph:

(-6, 3) and (6, 1)

[tex]\boxed{slope = \frac{y1 - y2}{x1 - x2} }[/tex]

Slope

[tex] = \frac{3 - 1}{ - 6 - 6} [/tex]

[tex] = \frac{2}{ - 12} [/tex]

[tex] = - \frac{1}{6} [/tex]

Substitute the value of the slope into m in the equation:

[tex]y = - \frac{1}{6} x + c[/tex]

To find the value of c, substitute a pair of coordinates into the equation.

When x= 6, y= 1,

[tex]1 = - \frac{1}{ 6} (6) + c[/tex]

1= -1 +c

c= 1 +1

c= 2

Thus, the equation of the line is y= -⅙x +2.

The y-intercept can also be derived from the graph as we can see that the line passes through the y- axis at (0, 2). This point can also be used to find the slope of the line too.

Answer:

a. Breakfast is 10 & Lunch is 15

Step-by-step explanation:

25 = 50%

x = 30%

y = 20%

1% = 0.5 because 25/50= 0.5

0.5 x 30 = 15 and 0.5 x 20 = 10

Answer: the slope is -1, and the y-intercept is 5.

Step-by-step explanation:

To find the slope and y-intercept, we change the equation to y = mx + b form, where m is the slope and b is the y-intercept.

3y + 3x = 15  (Minus 3x to both side)

        3y = -3x + 15  (Divide 3 from the both side, to get in term of y)

          y = - x + 5

Using y = mx + b form, in this case, the slope is -1, and the y-intercept is 5.

Answer:

fg(x)=f(g(x)

=f(x-5)

But ;f(x)=x+2

f(x-5)=(x-5)+2

=x-5+2

fg =x-3

gf(x)=g(f(x))

=g(x+2)

But ;

g(x)=x-5

g(x+2)=(x+2)-5

=x+2-5

=x-3

g(g)=g(x-5)

g(x-5)=(x-5)-5

=x-5-5

=x-1
