Answer:x=7 and y=9

Step-by-step explanation:

y=x+2

y=2x-5

Rearrange we get

x-y=-2

2x-y=5

Solve simultaneously we gets

Using elimination method

-x=-7

x=7

Substitute for x in equation I

x-y=7

7-y=-2

y=9

Answer:

X=7

Y=9

Step-by-step explanation:

.y=x+2

y = 2x - 5

Use equivalents y=y so you get:

X+2=2x-5

X-2x=-5-2

-x=-7

X=7

Y=x+2=7+2=9

You made two deposits to your bank accounts this month. One deposit was $17.92, and the second deposit was $15.33. Your balance

WITCHER [35]

$72.31 is the total amount AFTER ADDING TWO DEPOSITS

So, if we want to know the amount before deposits, we just need to take the total of previous two deposits

The expressions that show your balance would be

$72.31 – $17.92 – $15.33; $39.06

Factor 64 - P.<br> (8 - x(8 - x)<br> (8 + x (8 - x)<br> (X + 8)(x-8)

muminat

Question:

Factor $64-x^2$

(8 - x)(8 - x)

(8 + x) (8 - x)

(X + 8)(x-8)

Answer:

Option B: $(8+x)(8-x)$ is the factor

Explanation:

Given that the expression is $64-x^2$

We need to find the factor of the given expression.

Let us rewrite the expression as $8^2-x^{2}$

Since the expression is of the form $a^2-b^2$ , let us use the identity $a^2-b^2=(a+b)(a-b)$

where a = 8 and b = x

Substituting the values in the identity, then the expression can be written as

$8^2-x^{2}=(8+x)(8-x)$

Thus, the factor of the expression is $(8+x)(8-x)$

Hence, Option B is the correct answer.
