Answer: {y,x} = {4,2} ) ) ) )4

Step-by-step explanation: y

[2] y = -2x + 8

// Plug this in for variable y in equation [1]

[1] (-2x+8) - x = 2

[1] - 3x = -6

// Solve equation [1] for the variable x

[1] 3x = 6

[1] x = 2

// By now we know this much :

y = -2x+8

x = 2

// Use the x value to solve for y

y = -2(2)+8 = 4

Solution :

{y,x} = {4,2}

2x+1x+2=8
3x+2=8
-2 -2
3x=6
divide 3 on both sides
x= 2

An isosceles right triangle has a hypotenuse length that can be modeled with the function h(x) = sqaure root of 2 The combined

larisa [96]

The legs are defined by $L(x) = 2x$ . The Hypotenuse if defined by $h(x) = L(x)\cdot \sqrt{2}$ . The perimeter is defined by:

$p(x) = h(x)+2\cdot L(x) \\~\\p(x) = L(x)\cdot\sqrt{2} +2\cdot L(x) \\~\\p(x) = L(x)\cdot\left(\sqrt{2}+2\right) \\~\\p(x) = 2x\cdot\left(\sqrt{2}+2\right) \\~\\p(x)= 2\sqrt{2}x+4x$

D. P(x) = 2x √2 + 4x

If < A and < B form a linear pair, and < A = x - 13 degrees, and < B = x + 7 degrees, then find x. Select one: a. 12

Andreas93 [3]

The correct value of "x" will be "93".

According to the question,

A linear pair of sum to 180°,

then

→ $x-13+x+7=180$

→ $2x -6=180$

By adding "6" both sides of the equation, we get

→ $2x-6+6=180-6$

→ $2x=186$

→ $x = \frac{186}{2}$

→ $x = 93$

Thus "option d" is the right answer.

Which is a correct two column proof. Given <4 and

vladimir1956 [14]

The initial statement is: QS = SU (1)

QR = TU (2)

We have to probe that: RS = ST

Take the expression (1): QS = SU

We multiply both sides by R (QS)R = (SU)R

But (QS)R = S(QR) Then: S(QR) = (SU)R (3)

From the expression (2): QR = TU. Then, substituting it in to expression (3):

S(TU) = (SU)R (4)

But S(TU) = (ST)U and (SU)R = (RS)U

Then, the expression (4) can be re-written as:

(ST)U = (RS)U

Eliminating U from both sides you have: (ST) = (RS) The proof is done.

The price of a video game was reduced from $60 to $45. By what percentage was the price of the video game reduced?* O 15% O 25%

Naya [18.7K]

Answer:

Step-by-step explanation:

The new price, $45, can be expressed as a percentage of $60 by taking it as a fraction of $60, converting to a decimal value, and multiplying by 100%. $45/$60=3/4=0.75, 0.75x100%=75%. So since 100%-75%=25%, the value was reduced by 25%.
