Solve the system by back substitution.

z + w =2
-2w = -6

Solution should be set like {( _ , _ , _ , _ )}

Answers

The values of all the variables are:

w = -3z = 5y = -16x = 33 approx

What are equations?A mathematical statement made up of two expressions joined by an equal sign is known as an equation. 3x - 5 = 16 is an example of an equation. We get the value of the variable x as x = 7 after solving this equation.

Given equations:

-4x - 8y - 2z - 6w = 53y + 18z + 6w = 24z + w =2-2w = -6

To find the values of x, y, w, and z:

-2w = -6w = -6/2w = -3

Substitute (w = -3) in z + w = 2:

z + w = 2z -3 = 2z = 2 + 3z = 5

Substitute (w = -3) and (z = 5) in 3y + 18z + 6w = 24:

3y + 18z + 6w = 243y + 18(5) + 6(-3) = 243y + 90 - 18 = 243y + 72 = 243y = 24 - 723y = - 48y = - 16

Substitute (y = - 16), (w = -3) and (z = 5) in -4x - 8y - 2z - 6w = 5

-4x - 8y - 2z - 6w = 5-4x - 8(-16) - 2(5)  - 6(-3) = 5-4x + 128 - 10 + 18 = 5-4x + 118 + 18 = 5-4x + 136 = 5-4x = 5 - 136-4x = - 131x = 131/4x = 32.75Rounding off: x = 33

Find the slope of the line passing through the pair of points or state that the slope is undefined. Then indicate whether the line through the points rises, falls, is horizontal, or is vertical
(7.1) and (2.1)

Answers

The slope of the line passing through the pair of points is

Given points are:

A (7,1) = (x₁ , y₁)

B (2,1) = (x₂ , y₂)

slope of a line is : y₂ ₋ y₁/x₂ ₋ x₁

Slope equals a height change /Change in width. You may also say that a slope is a climb or a run. This formula changes if the graph's horizontal axis is represented by x and the vertical axis by y.

Assume that the line's slope is'm'.

m = y₂ ₋ y₁/x₂ ₋ x₁

m= 1 ₋ 1/2 ₋ 7

m = 0/₋5

m = 0

hence, when the slope is 0 then the line is horizontal .

Therefore, the slope is 0 which indicates that the line is horizontal.

Recall the equation for a circle with center ( h , k ) and radius r . At what point in the first quadrant does the line with equation y = 0.5 x + 2 intersect the circle with radius 5 and center (0, 2)?

Answers

At (4.472 , 4.236) in the first quadrant , the line with equation y = 0.5 x + 2 intersect the circle with radius 5 and center (0, 2) .

The equation of circle with center (h,k) and radius r can be written as

(x-h)²+(y-k)²=r²

In the given question

the center of the circle is (0,2) and the radius of the circle is 5 .

So the equation of circle become

(x-0)²+(y-2)²=5²

x²+(y-2)²=25     ...(i)

It is given that y=0.5x+2 intersects the circle

y = 0.5x+2

Rewriting the equation we get

y-2=0.5x

(y-2)=0.5x

x=(y-2)/0.5

x = 2(y-2)        ...(as 0.5=1/2)       ....(ii)

Squaring both sides

x² = (2(y-2))²

x² = 2²(y-2)²

x² = 4(y-2)²     ...(iii)

Substituting the value of equation (iii) in equation (i) we get ,

4(y-2)²+(y-2)²=25

5(y-2)²=25

(y-2)²=25/5

(y-2)²=5

Taking Square root both the sides , we get

√(y-2)²=√5

y-2 = √5

y=(√5)+2

y=2.236+2

y=4.236

Substituting the value of y in (ii) we get

x=2(4.236-2)

x=2*2.236

x=4.472

Therefore ,  the circle with radius 5 and center (0, 2) will intersect  the line with equation y = 0.5 x + 2  in the first quadrant at (4.472 , 4.236).

In linear equation 125 degrees is the measure of exterior angle formed on the ground.

What in mathematics is a linear equation?

There are only one or two variables in a linear equation. No variable can be multiplied by a number larger than one or used as the denominator of a fraction in a linear equation. All of the points fall on the same line when you identify the values that together make a linear equation true and plot those values on a coordinate grid.

we know that the sum of all the angles of a triangle is 180

therefore

You need a 25% alcohol solution. On hand, you have a 325 mL of a 20% alcohol mixture.
You also have 50%
alcohol mixture. How much of the 50% mixture will you need to add to obtain the desired solution?

You will need


mL of the 50% solution

Answers

We need 65 ml of 50% mixture to obtain the desired solution.

Here, we need to make a 25% alcohol solution by mixing some amount of 50% alcohol mixture with 325 mL of a 20% alcohol mixture.

Let the amount of 50% alcohol solution be x

The the quantity of alcohol in 50% alcohol solution = 50% of x

= 0.5x

Similarly the the quantity of alcohol in 20% alcohol solution = 20% of 325

= 65ml

The total quantity of 25% alcohol solution = (325 + x) ml

Thus, the the quantity of alcohol in 25% alcohol solution = 25% of (325 + x)

= 0.25 (325 + x)

= 81.25 + 0.25x

Thus, we can form the following equation-

0.5x + 65 = 81.25 + 0.25x

0.5x - 0.25x = 81.25 - 65

0.25x = 16.25

x = 16.25/ 0.25

x = 65

Thus, we need 65 ml of 50% mixture to obtain the desired solution.
