Answer:

You would write it like -

y = 7 + 4x

or y = 4x + 7

Y = 4x+7 should be correct! always use the equation y=mx+b, m is the constant and y is be :)

Answer:

y - 3= 2(x - 0)

Step-by-step explanation:

hello :

note 1 :

the point-slope formula is :

y - y_1 = m(x - x_1) the point is A(x_1 , y_1 ) , m : the slope

note 2 :

the slope is : m = (y_2 - y_1)/(x_2 -x_1) when given two points :

A(x_1 , y_1 ) and B(x_2 , y_2 )

in this exercice : x_1 =0 y_1 =3 x_2 =1 y_2 =1

calculate now m = (1 - 3)/(1 -0) =-2

an equation in point-slope form is : y - y_1 = m(x - x_1)

y - 3= 2(x - 0)

Answer: b. The adjacent angles formed by two intersecting lines are supplementary.

Step-by-step explanation:

In the given picture , we can see that there are intersecting lines with adjacent angles which have shown.

If we add the adjacent angles for each pair of intersecting lines we get,

$135^{\circ}+45^{\circ}=180^{\circ}$

$130^{\circ}+50^{\circ}=180^{\circ}$

$160^{\circ}+20^{\circ}=180^{\circ}$

Therefore,b is the right option "The adjacent angles formed by two intersecting lines are supplementary."

Two Angles are supplementary when their sum is 180 degrees.

Two Angles are complementary when their sum is 90 degrees.
Vertical angles are always equal.

a man buys a dozen cameras for $1800. He sells them at a profit of $36 each. Express his profit as a percentage of his selling p

Helga [31]

First of all, we need to deduce the price of a single camera:

$\dfrac{1800}{12}=150$

Now, we know that he profits 36 dollars from each camera. So, we are asking: which percentage of 150 is 36? We have

$36 = 150\cdot\dfrac{x}{100}$

This equation literally says: 36 is x-percent of 150. And we need to solve for x:

$x=\dfrac{36\cdot 100}{150} =24$
