Step-by-step explanation:

Answer:

A = (0,-6)

B = (0,4)

C = (3,-9)

Step-by-step explanation:

Take the middle number of the x-coordinates.

A- The number in between 0 and 0 is 0

B- The number in between 2 and -2 is 0

C- The number in between -3 and 9 is 3

Take the middle number of the y-coordinates.

A- The number in between 0 and -12 is -6

B- The number in between 9 and -1 is 4

C- The number in between -3 and -15 is -9

You can also use the midpoint formula; M=(x(1) + x(2))/2 , (y(1) + y(2))/2

Answer:

11 yards.

Step-by-step explanation:

The area of a square is A= s²

Since the area is given as 121, you just take the square root.

[tex]\sqrt{121} = s^{2}[/tex]

s= 11 yards

Answer:

D

Step-by-step explanation:

Answer:

starting with 6 and adding 3 an hour over two days or 48 hours that  would be  3x48= 144 then add your original 6 that would be 150

Step-by-step explanation:

6 + (3x48) = logs for two days

6 + 144 = 150

150!!!

a. The number of logs needed for one night can be represented by the expression:

6 + 3h

b. The expression for the number of logs needed for 2 nights is 12 + 6h.

A term is a single mathematical phrase. It might consist of only one variable—a letter—one number—positive or negative—or several variables multiplied but never added or subtracted. A number is placed in front of some nouns that have variables. Coefficients are numbers that come before phrases.

If Nelson plans to start the fire with 6 logs and add 3 logs for each hour the fire burns, then the number of logs needed for one night can be represented by the expression:

6 + 3h

where h is the number of hours the fire burns.

To find the number of logs needed for 2 nights, we can simply multiply the number of logs needed for one night by 2:

2(6 + 3h)

Simplifying this expression gives:

12 + 6h

So the expression for the number of logs needed for 2 nights is 12 + 6h. This represents starting the first night's fire with 6 logs, adding 3 logs per hour for that night, and then starting the second night's fire with 6 logs again, and adding 3 logs per hour for that night as well.

Given:

The parent sine function is [tex]f(x)=x^2[/tex].

It shifts three units to the left and four units down.

To find:

The new function.

Solution:

The translation is defined as

[tex]f_1(x)=f(x+a)+b[/tex]                .... (1)

Where, a is horizontal shift and b is vertical shift.

If a>0, then the graph shifts a units left and if a<0, then the graph shifts a units right.

If b>0, then the graph shifts b units up and if b<0, then the graph shifts b units down.

Graph shifts 3 units to the left. So, a=3.

Graph shifts 4 units down. So, b=-4.

Putting a=3 and b=-4, we get

[tex]f_1(x)=f(x+3)-4[/tex]

[tex]f_1(x)=(x+3)^2-4[/tex]          [tex][\because f(x)=x^2][/tex]

Here, new function is also defined by f(x). So, [tex]f(x)=(x+3)^2-4[/tex].

Therefore, the correct option is d.

Step-by-step explanation:

30% of 10 = [tex]\frac{30}{100}*10 = 3 \neq 6\\\\[/tex]

B) 60% of 15 = [tex]\frac{60}{100}*15 = \frac{6}{10}*15=\frac{3}{5}*15=3*3 = 9 \neq 6\\[/tex]

c) 50% of 12 = [tex]\frac{50}{100}*12=\frac{1}{2}*12=6\\\\[/tex]

D) 20% of 30 = [tex]\frac{20}{100}*30=\frac{1}{5}*30= 6[/tex]

E)75% of 8 = [tex]\frac{75}{100}*8 = \frac{3}{4}*8=3*2 = 6[/tex]

Answer:

the question is when are the two accounts equal... so our strategy is to find two equations and set them equal to each other

Step-by-step explanation:

weeks = w

steve's acct. = 250-25w

Chelsea's acct. = 30 +30w

so when do they equal

250-25w = 30+30w

now  solve for w

250-30 = 30w +25w

220 = 55w

4 = w

In four weeks.. they will have the same

so 250- 25(4) = 150  

and to check  30+30(4) = 150

so the each have $150.00 in their accts at 4 weeks

Hello!

[tex]\large\boxed{\log_{7}{(\frac{12m}{n}})}[/tex]

Use the log properties to simplify:

log (a) + log (b) = log (a · b)

log (a) - log (b) = log (a ÷ b)

Therefore:

[tex]log_{7}12 + log_{7}m - log_{7}n\\\\= log_{7}(12 * m / n}\\\\log_{7}{(\frac{12m}{n}})[/tex]

Answer: Slope = 10.000/2.000 = 5.000

x-intercept = 7/-5 = -1.40000

y-intercept = 7/1 = 7.00000

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

y-2-(5*(x+1))=0

Equation of a Straight Line

3.1 Solve y-5x-7 = 0

Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).

"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.

In this formula :

y tells us how far up the line goes

x tells us how far along

m is the Slope or Gradient i.e. how steep the line is

b is the Y-intercept i.e. where the line crosses the Y axis

The X and Y intercepts and the Slope are called the line properties. We shall now graph the line y-5x-7 = 0 and calculate its properties

Graph of a Straight Line :

Calculate the Y-Intercept :

Notice that when x = 0 the value of y is 7/1 so this line "cuts" the y axis at y= 7.00000

y-intercept = 7/1 = 7.00000

Calculate the X-Intercept :

When y = 0 the value of x is 7/-5 Our line therefore "cuts" the x axis at x=-1.40000

x-intercept = 7/-5 = -1.40000

Calculate the Slope :

Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is 7.000 and for x=2.000, the value of y is 17.000. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of 17.000 - 7.000 = 10.000 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)

Slope = 10.000/2.000 = 5.000

Geometric figure: Straight Line

Slope = 10.000/2.000 = 5.000

x-intercept = 7/-5 = -1.40000

y-intercept = 7/1 = 7.00000
