The measures of three angles of a quadrilateral are 70, 125, and 89 degrees. Find the measure of the fourth one.​

Answer:

[tex] f(-1) =\boxed{-11}\\ f(0) =\boxed{-4}\\f(2) =\boxed{14}[/tex]

Step-by-step explanation:

[tex]f(x)=\begin{cases} 9x -2 \:\: x < 0\\ 9x-4 \:\: x \geq 0\end{cases}\\\\\because \; -1 \: is \: less\: than \: zero\\\therefore f(-1) \: lies \: in \: the \: interval\: x<0\\\\f(-1) = 9(-1) -2 = -9-2 = -11\\f(-1)=\boxed{-11}\\\\Similarly,\: f(0) \:\&\: f(2)\: lies \: in \: the \: interval\: x\geq 0\\\\f(0) = 9x-4 = 9(0) - 4 = 0-4 = -4\\f(0) = \boxed{-4}\\\\f(2)=9x-4 = 9(2)-4 = 18-4 = 14\\\\f(2)=\boxed{14}[/tex]

Answer:

17 = 3x+8

Step-by-step explanation:

since both equations are equal to y...

y = 2x + 10

y = -4x - 2

2x + 10 = y = -4x - 2

2x + 10 = -4x - 2

2x + (4x) = -2 + (-10)

6x = -12

x = -2

______________________________

plug in x = -2 into one of those equations: I will use y = 2x + 10

y = 2(-2) + 10

y = -4 + 10

y = 6

______________________________

okay, so I rechecked my answers several times, and I still got (-2,6)

That MC question has an error since none of the answer choices fit.

Inform your teacher about this.

(I'd say choose that (-3,4) since it works only for one equation y = 2x +10 .... maybe your teacher was supposed to use the other equation instead of y = -4x - 2)

Step-by-step explanation:

x = 1.0

how:

we know that the Hyp of the small triangle is  [tex]\sqrt{2}[/tex]

since we know that ,  then  

[tex]\sqrt{2}[/tex] = 1^2 + 1^2   by  Pythagoras theorem

so each side is 1  :)

Step-by-step explanation:

Answer:

[tex]A=(x+4)^2\text{ or } A=x^2+8x+16[/tex]

Step-by-step explanation:

We have a square garden. One side of the garden has a length of (x + 4).

And we want to write an expression that could represent the area of the garden.

Remember that for a square, all sides have equivalent lengths. So, every side measures (x + 4). The area of a square is given by:

[tex]A=s^2[/tex]

Where s is the length of one side.

Substitute:

[tex]A=(x+4)^2[/tex]

Expand if desired. Hence, the expression for the area is:

[tex]A=x^2+8x+16[/tex]

Answer:

67%

Step-by-step explanation:

First of all, we must find the decrease;

39 - 13

=26

Then we can find the percentage decrease

26/13 ×100 =66.666..which can be written as 67.

Step-by-step explanation:

The correct order in which accounting cycles are performed helps in structuring and produce an efficient result in the day-to-day activities of any business organization.  This cannot be found in the options given but the correct order is shown below.

1, 2, 3, 4, 5, 6, 9, 8, 7

In other textbooks, it was stated that option A is correct for part 1.

The wide range of various entries or steps of the accounting cycle will happen depending on the circumstance yet these three activities are there any in the business association independent of circumstances.

1, 2, 3

In other textbook, it was stated that option B is correct for part 2.

Answer:

(245 / (6^2 - 1)) + 15 = 22

Step-by-step explanation:

Well we need to divide 245 by something - and by something that divides it, otherwise we can't solve this. It's not divisible by 6^2 = 36, it's not divisible by 6^2 - 1 + 15 = 50 and it's not divisible by 6^2 - (1 + 15) = 20. Our only option is (6^2 - 1) = 35

245/35 = 7 and we notice that 7 + 15 = 22, so we've solved it.

Answer:

The first one because it is equal to 94.5 round it off get 95

Answer: 3/2x63

Step-by-step explanation:

Without doing the math, you can look at these to determine if they would be less than or more than 63.

In order for the product to be more than 63, we need a number greater than 1.

7/8 is less than 1. (8/8 would be equal to 1)

2/3 is less than 1. (3/3 would be equal to 1)

4/5 is less than 1 (5/5 would be equal to 1)

3/2 is greater than 1. (2/2 would equal one.)

3/2 is equivalent to 1 and 1/2. (2 goes into 3 1 time with one left over. Place the “leftover” back on top of the denominator)

Alternatively, you could do the math for each possibility by multiplying across the top and dividing by what’s on bottom.

Ex 3/2x 63 = (3x63)/2 =94.5

Answer:

22 miles in 11 hours!

Step-by-step explanation:

We already know a ghost crab can travel 12 miles in 6 hours.

Now, we just need to find the how many miles per hour the crab walks.

We simply divide 12 miles by 6 hours which gives us 2 miles in 1 hour.

That means, we multiply 11 by 2 which gives us 22 miles!

The ghost crab can travel 22 miles in 11 hours. When you find the rate of change by dividing 12 by 6, it gives you 2 m/h. That enables you to find the amount of miles by multiplying 11 hours by two which gives you 22!

Answer:

d=-1

Step-by-step explanation:

10(1+3d)= -20

divide both sides by 10

1+3d=-2

move the costant to the right, change the sign

3d=-2-1

caclulate

3d=-3

divide both sides by 3

d=-1

Answer:

y= -2x+4

Step-by-step explanation:

1) if they want an equation where y depends on x, then you need to write the equation in slope-intercept form.  Or... y=mx+b  where m is the slope and b in the y-intercept.

2) looking at the line, it intercepts y at 4, so that is your intercepts or "b"

3) the slope is the change in the y values over the change in the x values for any two points.  Notice if you choose the point (0,4) and (2,0) the change in the y values is -4 and the change in the x values is 2.  Therefore, the slope is -4/2 or -2.  -2 is your m.

4) once you plug those values in to y=mx+b, you have y= -2x+4
