Y=40x+65
145=40x+65
145-65= 40x
80=40x
80/40=x
x=2

You have to find the domain and range
Dahasolnce [82]

Answer:

First off, we look for which circles are open or closed.

We start with an open interval since the circle on the left is open and end with a closed interval since the circle on the right is closed.

Domain is all x values, Range is all y values

The graph shows the continous function going from -3 to 1 on the x axis.

According to the circles, this means our domain will be (-3,1].

Now, the range doesn't care about if its closed or not. So we can say the graph is on the y axis from -4 and 0. This means the range is -4<y<0

I used different notations for both just incase you need to represent your answer differently :)

-3<x<1 & (-3,1] . Range is [-4,0]. 0>y>-4 looks correct as-well.

Mary wants to do a cheesecake. She needs 4 1/2 cups of sweet cream. She knows that 1
Travka [436]

Answer:

36 ounces

Step-by-step explanation:

If 1 cup equals 8 ounces, you would multiply 4 1/2 by 8. 8 x 4 is 32 (ounces), and half of 8 is 4, so 4 ounces. You would then add 32 and 4 together to get your answer. Hope this helps!!

What is<br> The equation of the line that passes through the points (5,-1) and (4,-5)
Murljashka [212]

For this case we have that by definition, the equation of the line in the slope-intersection form is given by:

y = mx + b

Where:

m: It is the slope of the line

b: It is the cut-off point with the y axis

We have two points through which the line passes:

(x_ {1}, y_ {1}) :( 5, -1)\\(x_ {2}, y_ {2}) :( 4, -5)

We found the slope:

m = \frac {y_ {2} -y_ {1}} {x_ {2} -x_ {1}} = \frac {-5 - (- 1)} {4-5} = \frac {-5+ 1} {- 1} = \frac {-4} {- 1} = 4

Thus, the equation is of the form:

y = 4x + b

We substitute one of the points and find b:

(x,y):(5,-1)\\-1=4(5)+b\\-1=20+b\\-1-20=b\\b=-21

Finally, the equation is:

y = 4x-21

Answer:

y = 4x-21

Natali5045456 [20]
Area of rectangle = 24/54 square miles
length(L) = 5/9 miles
width (W)= ?
area = L * W
25/54 = 5/9 * W
W =  (25/54) / (5/9) = (25 * 9) / (54 * 5)
 W = 5/6 miles
