Answer:

x = 6 , y = 8 ( 6 , 8 )

Step-by-step explanation:

If we solve the linear system that you gave us,

y = 5x – 22

3x +2y=34

We get that x is 6 and y is 8.

In other words, since it's a point, it should be, ( 6 , 8 )

Answer:

w = [tex]l + \frac{25 - l^{2}}{l - 5}[/tex]

(Anyone can correct me if I'm wrong)

Step-by-step explanation:

Before we start the solving, we can make the following statements:

Area = l x w

Area = 5x + 25

therefore,

l x w = 5x + 25

Since the question states that the length is x more than the width, so we can make the following statement:

w = l + x

With this, we can substitute it to the first statement we made, l x w = 5x + 25,

l x (l + x) = 5x + 25

[tex]l^{2}[/tex] + lx = 5x + 25

lx - 5x = 25 - [tex]l^{2}[/tex]

x(l - 5) = 25 - [tex]l^{2}[/tex]

x = [tex]\frac{25 - l^{2}}{l - 5}[/tex]

From this, we can find w by substituting it in the statement we made earlier, w = l + x,

w = [tex]l + \frac{25 - l^{2}}{l - 5}[/tex]

Answer:

Step-by-step explanation:

first thing you didn't give any quadratic equation and also didn't allude which method you indeed however I'll give you two methods

to get elaborately factoring method

see this question which is answered by me

quadratic formula:

by using this formula we can solve quadratic very early

we just need to substitute the value of a,b and c and simply to get x

Example 1 – Solve: Example 1

Step 1: Identify a, b, and c and plug them into the quadratic formula. In this case a = 1, b = –8, and c = 14.  

Step 1

Step 2: Use the order of operations to simplify the quadratic formula.  

Step 2

Step 3: Simplify the radical, if you can. In this case you can simply the radical into:  

Step 3

Step 4: Reduce the problem, if you can. In this case you can reduce the entire problem by 2.  

1. 12 (i think)

i don't know about question 2

Answer: -8 > -6

Step-by-step explanation:

Answer:

13.6 units (to 3 significant figures)

Step-by-step explanation:

C ( -4,6) and D (-4,-5)

the formula for distance is : √(x2 - x1)² + (y2-y1)²

in this case x1= -4 , x2= -4 and y1 =6 , y2 = -5

so substitute the values and you will get the answers

Answer:

x = 111°

Step-by-step explanation:

The interior sum of a triangle is 180°

x + 37 + 32 = 180

x + 69 = 180

x = 111

good luck, i hope this helps :)

option ( D ) is correct

Answer:

{1}

Step-by-step explanation:

A ∩ B ∩ C means A intersection B intersection C. That means the question is asking for a set of numbers that are in sets A, B, and C.

{1} is the answer since it is the only number that is in all three sets.

Answer:

Step-by-step explanation:

The area of a trapezoid is the average of the parallel bases times the height or distance between the two bases

A=h(b1+b2)/2

Here we have h=8cm, b1=6cm, and b2=11cm so

A=8(6+11)/2

A=8(17)/2

A=4(17)

A=68 cm^2

Answer:

  36π mm²

Step-by-step explanation:

You know that (ab)² = a²b². This tells you that ...

  πr² = π(6 mm)² = π(6² mm²) = 36π mm²

The units of area are square millimeters (mm²).

Additional comment

For a variety of reasons, I find it is often helpful to keep units of measure with the associated number. It serves as a check on the arithmetic, among other things. If the units don't make sense, chances are good that the math doesn't make any sense.

It should be fairly obvious that if linear dimensions are in millimeters, then the corresponding area dimensions will be square millimeters. (Volume will be cubic millimeters.)

In the math, the units can be treated in the same way as any other variable. This tells you, for example, that you can only add (or subtract) measures with the same units (like terms). Division can be used to cancel same units, or to get from volume to area, for example (mm³/mm = mm²).
