Solve the following system:

{y = 5 x + 2 | (equation 1)
{3 x = 10 - y | (equation 2)
Express the system in standard form:

{-(5 x) + y = 2 | (equation 1)
{3 x + y = 10 | (equation 2)

Add 3/5 × (equation 1) to equation 2:
{-(5 x) + y = 2 | (equation 1)
{0 x+(8 y)/5 = 56/5 | (equation 2)

Multiply equation 2 by 5/8:
{-(5 x) + y = 2 | (equation 1)
{0 x+y = 7 | (equation 2)


Subtract equation 2 from equation 1:
{-(5 x)+0 y = -5 | (equation 1)
{0 x+y = 7 | (equation 2)

Divide equation 1 by -5:
{x+0 y = 1 | (equation 1)
{0 x+y = 7 | (equation 2)

Collect results:
Answer:  {x = 1                         {y = 7

navik [9.2K]

Answer:

If Lance got home from school at 3:32 p.m. A and B both represent:

A: seventeen minutes before 3 would be before 3 o'clock even happens

B: 28 minutes before 4 would make more sense, since 3:32 is before 4 o'clock

Lance got home 28 minutes before 4

Hope this helps ;)

goldenfox [79]

Answer:

Option D y=3

Step-by-step explanation:

The question in English is

Which of the following functions is a constant function?

we know that

A <u>constant function</u> is a function whose output value is the same for every input value

so

<u><em>Verify each case</em></u>

case A) y=x+1

This is not a constant function, this is a linear equation

Is a function whose output value is different for every input value

case B) y=x+2

This is not a constant function, this is a linear equation

Is a function whose output value is different for every input value

case C) x=y+3

This is not a constant function, this is a linear equation

Is a function whose output value is different for every input value

case D) y=3

This is a constant function

Is a function whose output value is the same for every input value

Hüseyin draws a fox with a scale of 3 units on his graph paper represents 15cm. The fox has an actual height of 80cm. What is th
Over [174]

Answer:

The height of the fox in Huseyin's drawing is, 16 units

Step-by-step explanation:

Proportion states that the two ratios or fractions are equal.

As per the statement: Huseyin draws a fox with a scale of 3 units on his graph paper represents 15 cm. The fox has an actual height of 80 cm.

⇒ We are given Scale of 3 units.

On graph paper the length of fox is 15 cm.

The fox has an actual height = 80 cm

let x be the height in units of the fox in Huseyin's drawing.

By definition of proportion;

\frac{3}{15} = \frac{x}{80}

by cross multiply we get;

3 \times 80 = 15x

Simplify:

240 = 15x

Divide both sides by 15 we get;

x = 16 units.

Therefore, the height of the fox in Huseyin's drawing is, 16 units
