Y = -3
x = 4

5x + 3y = 11 [1]
2x - 7y = 29. [2]

[1]*2
10x +6y = 22 [3]

[2]*5
10x - 35y = 145. [4]

[4]-[3]
-41y = 123
y = -3
sub y into 5x +3y = 11

The difference between a number and five equals three. Translate this sentence to an equation and then find the
laila [671]

Answer:

the equation will be:

\mathbf{x-5=3}

solving the equation we get x=8

Option B is correct.

Step-by-step explanation:

We need to write equation for this sentence:

The difference between a number and five equals three.

Let number = x

So, the equation will be:

\mathbf{x-5=3}

Now, solving the equation to find value of x

x-5=3

Adding 5 on both sides

x-5+5=3+5\\x=8

So, solving the equation we get x=8

Option B is correct.

What is the equation in point slope form of a line that passes through the point (–8, 2) and has a slope of 1/2?
Kamila [148]
Point slope equation: 
y-y1=m(x-x1) 
m=slope

So we simply plug in our given information: 
x1=-8 
y1=2
m=1/2

y-2=1/2(x-(-8)  

2 minus signs next to each other make a positive 

Final answer: 
y-2=1/2(x+8)

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
