X-yz for x=-2 y=5 solve for z

Mathematics

mr_godi [17]3 years ago
7 0

Answer:

-5z - 2

Step-by-step explanation:

x - yz when x = -2 and y = 5

-2 - 5z

Since we don't have any like terms and an equal sign, we can't simplify any further.

Best of Luck!

Hi there!

Let me help you out a bit here. What we need to do is subtract the area of the smaller square from the area of the larger square. To do this, we first need to find the length of one of the larger sides. Since the outer polygon is a square, we can use the 45-45-90 relationship to determine that each side of the larger square is equal to 9 \sqrt{2}. Next, we can do the same thing for the smaller square, determining that one outer side of the smaller square is equal to 4 \sqrt{2}. To figure out the area of both squares, we need to square each of the outer lengths. This gives us 162 for the bigger square and 32 for the smaller square. Now, all we need to do is subtract 32 from 162. This gives us a value of 130cm^2 for the shaded area.

Hope this helps!! :)

If you start with Malvin’s age, take half of it, increase that result by 5, then divide by 3, and finally double that, you get 8
Kisachek [45]

Answer:

24 years old

Step-by-step explanation:

Let Malvin's age be x.

  • x / 2
  • x / 2 + 5 = 5x / 10  [ By taking the L.C.M.]
  • ( 5x / 10 ) * ( 1 / 3 ) = 5x / 30   [ Multiply with the reciprocal of 3 ]
  • ( 5x / 30 ) * 2 = 5x / 15

Now let's solve the equation,

5x / 15 = 8

       5x = 8 * 15

       5x = 120

         x = 120 / 5

         x = 24

Therefore, Malvin is 24 years old.

Hope yo liked the answer!!

Order them least to greatest. And explain
AnnyKZ [126]

Answer:

13. 1/2, 5/8, 3/4

16. 7/12, 3/5, 2/3

Step-by-step explanation:

make them have the same denominator.

13) 1/2 x 4 = <u>4/8</u>, <u>5/8</u>, 3/4 x 2= <u>6/8</u>

16) Grab two fractions let's say 3/5 and 2/3

Multiply 3/5 denominator (5) with 2/3 numerator (2)

It's 10 and place it above the number you multiplied the numerator from so it's above 2/3.  Do it again but with 2/3 denominator (3) and 3/5 numerator (3). Multiply 3 and 3 you get 9. Place the 9 above 3/5. We know that 9 is less than 10 so 3/5 is less than 2/3. You can do this with any two fractions.

Please help and explain!! I really don't get this
const2013 [10]
Average rate of change means find the slope of the secant line. So if there is a function f(x) and you want to find the average R.O.C over the interval [a,b], it would be (f(b)-f(a))/(b-a)

1. (f(3)-f(1))/(3-1)= (0-(-2))/2= 1, so D.

2. Same concept; (8-4)/(3-1)=2, so A.

3. Again, (39-(-1))/5= 8, B.
