How do I solve a system of equations algebraically with a substitution method and then write it as a coordinate point?

y = 3x -17 and y = -2x + 8

Answers

Answer 1
To solve it using substitution, you need to plug in one of the equations for y on the other. Since they both equal y, that means the equations also equal each other.

It would be:

3x - 17 = -2x + 8

Then solve. First you can add 2x to both sides.

5x - 17 = 8

Add 17 to both sides

5x = 35

Divide both sides by 5.

x = 5


Since we now have x, we can find y by plugging in 5 for x in any of the equations. I will use y = -2x + 8

y = -2(5) + 8

y = -10 + 8

y = -2


We now have both x and y. As a coordinate point, it would be (5, -2).

I have this math problem and it is: an equation in function from that reflects f(x)=3x over the line y=0.

Answer:

[tex]g(x) = -3x[/tex]

Step-by-step explanation:

Given

[tex]f(x) = 3x[/tex]

Required

Reflect over [tex]y = 0[/tex]

This means that we reflect over the x-axis

And the rule of reflection is:

[tex](x,y) \to (x,-y)[/tex]

Hence:

[tex]f(x) = 3x[/tex]

Will become:

[tex]g(x) = -f(x)[/tex]

So, we have:

[tex]g(x) = -3x[/tex]

Raul is flying a kite at the end of a string that is 200 feet long. Raul is holding the string 5 feet off the ground at the angle to the horizontal of 25. How high is the kite off the ground?

Answers

Answer:

Kite is 89.52 ft off the ground

Step-by-step explanation:

We are told that the string is 200 ft long.

That the string is 5 ft off the ground at an angle of 25° to the horizontal.

I have drawn a triangle to depict this illustration with x being the height of the kite from the end of the string.

Also, I have depicted the ground level which is 5 ft below the end of the string.

From the triangle, we can calculate the height of the kite above the end of the string using pythagoras theorem.

x/200 = sin 25

x = 200 sin 25

x = 200 × 0.4226

x = 84.52 ft

Now, the bottom of the kite is 5 ft off the ground as depicted in the attachment.

Thus, height of kite above the ground = 84.52 + 5 = 89.52 ft

Chin was shown the graph of a line that contained point (1, 7). He wrote f(x) = 4x + 3 to correctly represent the line. Which of these equations could represent the same line?

y – 7 = 3(x – 1)
y – 1 = 3(x – 7)
y – 7 = 4(x – 1)
y – 1 = 4(x – 7)

Answers

I think the answer is the third choice.

The equation that represents the same line containing point (1, 7) is as follows:

y - 7 = 4(x - 1)

Slope intercept form equation:y - y₁ = m(x - x₁)

where

m = slope

The graph of the line contains (1, 7) .He represent the line correctly as f(x) = 4x + 3.

The equation that represent the same line is as follows:

Using the model:

y = mx + b

Therefore,

m = 4

Finally , the equation is as follows:

y - 7 = 4(x - 1)

Se tienen 25 billetes de 5 y de 20 lempiras con un monto de 350 lempiras cuantos billetes de 5 lempiras se tienen y de 20 lempiras

Answers

Answer:

El número de facturas

5 lempiras = 10 billetes

20 lempiras = 15 billetes

Step-by-step explanation:

Vamos a representar

El número de facturas de

5 lempiras = x

20 lempiras = y

Nuestro sistema de ecuaciones se da como:

x + y = 25 ..... Ecuación 1

x = 25 - y

5 × x + 20 × y = 350

5x + 20y = 350 .... Ecuación 2

Sustituiríamos x por 25 - y en la ecuación 2

5 (25 - años) + 20y = 350

125 - 5 años + 20 años = 350

125 + 15 años = 350

15 años = 350 - 125

15 años = 225

y = 225/15

y = 15

Resolviendo para x

x = 25 - y

x = 25 - 15

x = 10

Por lo tanto, el número de facturas

5 lempiras = 10 billetes

20 lempiras = 15 billetes

Rita is spending more time at home to study and practice math. Her efforts are finally paying off. On her first assessment she scored 58 points, then she scores 63 and 68 on her next two assessments. If her scores continued to increase at the same rate, on which assessments will she be scoring above 85? Select all that apply. ​

Answers

Answer:

7th

Step-by-step explanation:

63 - 58 = 5

68-63 = 5

She is adding 5 points each time

a1 = 58

d = 5

a2 = 63

a3 = 68

a4 = 58+5 = 73

a5 = 73+5 = 78

a6 = 78+5 = 83

a7 = 83+5 = 88

This is the first assessment greater then 85, so the 7th assessment
