Answer:

y = 4x - 7

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

here m = 4 and c = 7, hence

y = 4x - 7 ← equation of line

Answer:

y = 4x - 7

Step-by-step explanation:

y = mx + b where m = slope and b = y-intercept

In this case m = 4 and y-intercept b = -7

Equation

y = 4x - 7

A circular region has a population of about 260000 people and a population density of about 135 people per square mine . find th
ValentinkaMS [17]

Answer:

24.76 mine

Step-by-step explanation:

The first thing is to calculate the area of the region, which we can calculate since we have the density and the population. The area would be the quotient between population and density:

260000/135 = 1925.93

The area would be 1925.93 square mine

We know that the area is given by:

A = pi * r ^ 2

we solve to r

r ^ 2 = A / pi

r ^ 2 = 1925.92 / 3.14

r ^ 2 = 613.3

r = 24.76

the radius is equal to 24.76 mine

What are the zeros of the function f(x) = x2 + 5x + 5 written in simplest radical form?
RideAnS [48]

Step-by-step explanation:

The function is as follows :

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

We need to find the zeroes of the function in the simplest radical form.The zero of the above function is given by :

x=\dfrac{-b\pm \sqrt{b^2-4ac} }{2a}

Here,

b = 5

a = 1

c = 5

So,

x=\dfrac{-5\pm \sqrt{5^2-4\times 1\times 5} }{2(1)}\\\\x=\dfrac{-5\pm \sqrt{25-20} }{2(1)}\\\\x=\dfrac{-5\pm \sqrt{5} }{2}

Hence, the correct option is (c).

If triangle abc is similar to triangle mno how do I solve for value of missing side
Doss [256]

Answer:

=2.4 cm

Step-by-step explanation:

In similar plane figures, the ratio of corresponding sides is a constant.

This constant is the linear scale factor.

In the provided example, 1.2cm corresponds to 0.96 while 3.0 corresponds to x

Thus, 1.2 cm/0.96 cm=3.0 cm/x

x=(3.0 cm×0.96 cm)/1.2 cm

=2.4 cm.

Rob is saving to buy a new MP3 player. For every $15 he earns babysitting, he saves six dollars. On Saturday, Rob earned $75 bab
nikitadnepr [17]
If he saves $6 from every $15 he gets, then getting $75 means he saves $30.
Lets says he is paid 15 dollars every hour, and from those he saved 6 dollars. If he earned 72 dollars, that means he is paid 5 times (because 75/15 is 5). So if every time he is paid he saves $6, being paid 5 times means he saves $30 ($6 *5).
