Name the like terms <br> 5a, 3, 4d , 2a, 2a, 5c

Vsevolod [243]

Answer:

"Like terms" are terms whose variables (and their exponents such as the 2 in x2) are the same. In other words, terms that are "like" each other. Note: the coefficients (the numbers you multiply by, such as "5" in 5x) can be different.

Step-by-step explanation: Hope this helps

Help please I'm not sure if I got it right, I'm a bit confused. 5th grade math

dmitriy555 [2]

Answer:

check your math

Step-by-step explanation:

The first subtraction was correct:

36 -7 3/4 = 28 1/4

The second subtraction needs to be revisited.

28 1/4 -6 2/4 = 27 5/4 -6 2/4 = 21 3/4

You can do what you did, but you need to pay attention to the signs.

28 1/4 -6 2/4 = (28 -6) +(1/4 -2/4) = 22 - 1/4 = 21 3/4

The result of subtracting 2/4 from 1/4 is -1/4, not +1/4.

Answer:

a) y=5ˣ-3

b) y=5ˣ⁻²

c) y=5^(x+1/2)

d) y=5^(x+2.5)+1

Step-by-step explanation:

$y=b*5^{ax-h}+k$

b: vertical stretch or compression and reflection across x-axis

a: horizontal stretch or compression and reflection across y-axis

h: horizontal shift (left and right)

k: vertical shift (up and down)

a) y=5ˣ-3

b) y=5ˣ⁻²

c) y=5^(x+1/2)

d) y=5^(x+2.5)+1

PLEASE HELP a three dight number has one more ten than it has hundreds, and it also has one more than twice as many units as ten

The reverse number of the three-digit number is 732

<h3>How to determine the reverse of the number?</h3>

Let the three-digit number be xyz.

So, the reverse is zyx

This means that

Number = 100x + 10y + z

Reverse = 100z + 10y + x

From the question, we have the following parameters:

y = x + 1

z = 1 + 2y

The sum is represented as:

100x + 10y + z + 100z + 10y + x = 10^3 - 31

100x + 10y + z + 100z + 10y + x = 969

Evaluate the like terms

101x + 101z + 20y = 969

Substitute y = x + 1

101x + 101z + 20(x + 1) = 969

101x + 101z + 20x + 20 = 969

Evaluate the like terms

101x + 101z + 20x = 949

121x + 101z = 949

Substitute y = x + 1 in z = 1 + 2y

z = 1 + 2(x + 1)

This gives

z = 2x + 3

So, we have:

121x + 101z = 949

121x + 101* (2x + 3) = 949

This gives

121x + 202x + 303 = 949

Evaluate the sum

323x = 646

Divide by 323

x = 2

Substitute x = 2 in z = 2x + 3 and y = x + 1

z = 2*2 + 3 = 7

y = 2 + 1 = 3

So, we have

x = 2

y = 3

z = 7

Recall that

Reverse = 100z + 10y + x

This gives

Reverse = 100*7 + 10*3 + 2

Evaluate

Reverse = 732

Hence, the reverse number of the three-digit number is 732
