Answer:

1. 0

2. -20

3. -7

Step-by-step explanation:

1. 0 times anything is equal to nothing times something.

So, the first one is 0.

2. For 4 x -5, you can just do 4 x 5 x -1, which equals 20 x -1, whixh equals -20.

3. Remember, a negative times a negative = a positive. So, the number must be negative. Just do 126 / 18 x -1, which equals -7.

Hope this helps!!

Three exterior angles of a pentagon measures 60,80and 90.Find the measure of other two exterior angle, assuming them equally Tha
julsineya [31]

Given:

The three exterior angles of a pentagon measures 60,80 and 90.

To find:

The measure of other two exterior angle, assuming them equally.

Solution:

Let x be the measure of two other exterior angles of the pentagon.

We know that the sum of all exterior angles of a pentagon is 360 degrees.

60^\circ+80^\circ+90^\circ+x+x=360^\circ

230^\circ+2x=360^\circ

2x=360^\circ-230^\circ

2x=130^\circ

Divide both sides by 2.

\dfrac{2x}{2}=\dfrac{130^\circ}{2}

x=65^\circ

Therefore, the measures of both exterior angles are 65 degrees.

Linear equation is equation in which each term has at max one degree. The function that can represent the given graph is y=2.0769x + 1.5.

<h3>What is linear equation?</h3>

Linear equation is equation in which each term has at max one degree. Linear equation in variable x and y can be written in the form y = mx + c

Linear equation with two variables, when graphed on Cartesian plane with axes of those variables, give a straight line.

For the given graph the equation can be written as, y = mx+c, this is because the graph is a line which means the relationship is linear. Therefore, the equation can be written as,

y = mx + c

Now, there are two points that are on the line and the coordinates of this points are,

A = (4, 9.5)

B = (7.25, 16)

Further the slope of the equation is,

m = (16-9.5) / (7.25 - 4) = 2.0769

Since c is the y-intercept of the graph, therefore, the value of c is 1.5.

Thus, the function that can represent the given graph is y=2.0769x + 1.5.

What is the equation of the line expressed in slope-intercept form?
Alisiya [41]
(x,y)
x=how far to the right
y=how far up
ok so
y=mx+b
m=slope
b=y intercept or where the line intercept the y axis

it looks like the line intercept the y axis at 2 high so
y=mx+2
we look at our options and we see that there is only 1 equation that has y=mx+2
that is B
B is the answer
