Answer:

x = -13

Step-by-step explanation:

Given that:

9-2x=35

Adding 2x-35 on both sides we get:

9 - 35 = 2x

-26x = 2x

Dividing both sides by 2

-13 = x

i hope it will help you!

Answer:

x = -13

Step-by-step explanation:

9 - 2x = 35

Subtract 9 from both sides.

-2x = 26

Divide both sides by -2.

x = -13

Can someone help me find this

PSYCHO15rus [73]

Step-by-step explanation:

In triangle,

 XYZ PYZ

XZ = PZ = 12cm

XY = PY = 5cm

YZ = YZ (Common side)

Hence,

As three sides of the two triangles are equal so,

Triangle XYZ is congruent to Triangle PYZ by SAS congruence condition

Which expression is not equivalent to the other expressions?

Paul [167]

-6(2x - 4) = -6*(2x) -6*(-4) = -12x + 24

-(12x - 6) + 18 = -12x + 6 + 18 = -12x + 24

-3(4x - 3) + 15 = -3*(4x) -3*(-3) + 15 = -12x + 9 + 24 = -12x + 24

-4(3x + 6) = -4*(3x) -4*(6) = -12x -24

All the expressions gave the same answer as -12x + 24, except for the last expression.

So, -4(3x + 6) is not equivalent to the others.

How to find surface area of a right triangular prism to the nearest whole number?

vovangra [49]

The area of the two triangular bases is
(total base area) = 2×(1/2)bh
= bh
= (10 m)(6 m) = 10·6 m² = 60 m²

The area of the three rectangles making up the remaining faces of the prism is
(total lateral area) = length×base + length×height + length×hypotenuse
= length×(base + height + hypotenuse)
= (16 m)(10 m + 6 m + 11.6 m)
= (16 m)(27.6 m) = 16·27.6 m² = 441.6 m²

Then the surface area of the prism is the sum of these
surface area = total base area + total lateral area
= 60 m² + 441.6² = 501.6 m²
When rounded to the nearest whole number, this is
A) 502 m²

Identify the function that contains the data in the following table:

Dmitriy789 [7]

Answer:

Option D is correct. f(x) = |x - 2| + 1

Step-by-step explanation:

Option A : f(x) = |x| + 1 INCORRECT

x = -2

we get, f(-2) = |-2| + 1 = 2 + 1 = 3 ≠ 5

⇒f(-2) is not equal to given value of f(-2).

Thus, This is not function of given data.

Option B f(x) = | x-2 | INCORRECT

put, x = -2

we get, f(-2) = |-2 - 2| = |-4| = 4 ≠ 5

⇒f(-2) is not equal to given value of f(-2).

Thus, This is not function of given data.

Option C : f(x) = | x-2 | - 1 INCORRECT

put, x = -2

we get, f(-2) = |-2 - 2| - 1 = |-4| - 1 = 4 - 1 = 3 ≠ 5

⇒f(-2) is not equal to given value of f(-2).

Thus, This is not function of given data.

Option D : f(x) = | x-2 | + 1 CORRECT

x = -2

f(-2) = |-2 - 2| + 1 = |-4| + 1 = 4 + 1 = 5

⇒f(-2) is equal to given value of f (-2).

x = 0

(0) = |0 - 2| + 1 = |-2| + 1 = 2 + 1 = 3

⇒f(0) is equal to given value of f (0).

x = 2

f(2) = |2-2| +1 = |0| + 1 = 0 + 1 = 1

⇒f(2) is equal to given value of f(2).

x = 3

we get, f(3) = |3-2| + 1 = |1| + 1 = 1 + 1 = 2

⇒f(3) is equal to given value of f(3).

x = 5

f(5) = |5 - 2| + 1 = |3| + 1 = 3 + 1 = 4

⇒f(5) is equal to given value of f(5).

Therefore, Option D is correct.
