So with this, I will be using the substitution method. With the first equation, substitute (y+3) into the x variable and solve for y:

y+3+y=7\\2y+3=7\\2y=4\\y=2

Next, now that we have the value of y, substitute it into either equation to solve for x:

x+2=7\\x=5\\\\x=2+3\\x=5

<u>And this is how you get your final answer (5,2).</u>

If f(x) = -2[x] + 8, what is f(-1.8)?<br> O 4 <br> O 6<br> O 10<br> O 12
lina2011 [118]

Answer:

12

Step-by-step explanation:

since the function is -2x+8 and you have been told to find f(-1.8) you have to replace -1.8 were there's x in the function.

f(x)=-2x+8

f(-1.8)=-2x+8

=-2(-1.8)+8

=3.6+8

=11.6 round off to 12

I hope this helps

2.4 Find the coordinates of the figure after reflecting in the x-axis. 1. D(-5, - 4), E(-5, -2), F(-1, -2), G(-1,-4)
posledela

Answer:

see explanation

Step-by-step explanation:

Under a reflection in the x- axis

a point (x, y ) → (x, - y ) , then

D (- 5, - 4 ) → D' (- 5, 4 )

E (- 5, - 2 ) → E' (- 5, 2 )

F (- 1, - 2 ) → F' (- 1, 2 )

G (- 1, - 4 ) → G' (- 1, 4 )

What quadratic function does the graph represent?
nekit [7.7K]

Answer:

f(x)=-\frac{1}{3}(x-2)^2+4,

Step-by-step explanation:

The function of the graph can be written in the vertex form as

f(x)=a(x-h)^2+k, where V(h,k)=V(2,4) is the vertex of the quadratic function.

We substitute the value to obtain;

f(x)=a(x-2)^2+4,

The point (5,1) lies on the graph so we use it to determine the value of a.

1=a(5-2)^2+4,

1-4=a(3)^2,

-3=9a,

a=-\frac{1}{3}

The required equation is

f(x)=-\frac{1}{3}(x-2)^2+4,

2. Suppose there are 6 million people in New York City that walk an average of 2.5 miles per day. If we add up all the miles wal
Lunna [17]

Answer:

  • 600 times

Step-by-step explanation:

<h3>Given</h3>

<u>Number of people:</u>

  • 6 million = 6*10^6

<u>Distance to walk:</u>

  • 2.5 miles per day per person

<u>Distance around the Earth</u>

  • 2.5*10^4
<h3>Solution</h3>

<u>Total distance walked:</u>

  • 6*10^6*2.5 = 15*10^6

<u>The ratio of total distance to the distance around the Earth:</u>

  • 15*10^6 / 2.5*10^4 = 6*10^2 = 600 times
