Write the expressions "Four times the difference of a number and 7 is 32", "One third of a number is 12 less than the number its
Anna71 [15]

<u>Part 1)</u> "Four times the difference of a number and 7 is 32"

Let

x--------> the number

we know that

the expressions is equal to

4(x-7)=32

therefore

<u>the answer part 1) is</u>

4(x-7)=32

<u>Part 2)</u> "One third of a number is 12 less than the number itself"

Let

x--------> the number

we know that

the expressions is equal to

\frac{1}{3} x=(x-12 )

therefore

<u>the answer part 2) is</u>

\frac{1}{3} x=(x-12 )

<u>Part 3)</u> "Ten increased by the quotient of a number and 2 is -15"

Let

x---------> the number

we know that

the expressions is equal to

10+ (\frac{x}{2} )= -15

therefore

<u>the answer Part 3) is</u>

10+ (\frac{x}{2} )= -15

<u>Part 4)</u> "One less than the product of a number and 3 is 5 more than the number itself"

Let

x---------> the number

we know that

the expressions is equal to

(3x)-1=5+x

therefore

<u>the answer Part 4) is</u>

(3x)-1=5+x

Y = -2x + 8<br> y = x^2 - 9x + 18<br><br> solve the system of nonlinear equation
ryzh [129]

Substitution

-2x+8=x^2-9x+18

x^2-7x+10=0

Factoring, we get

(x-5)(x-2)=0

x=5, x=2

If x equals 5,

y=-2(5)+8=

-10+8=

-2

Therefore, we derive our first solution:

<h2><u><em>x=5,</em></u></h2><h2><u><em>y=-2</em></u></h2>

Now we solve for our second x

If x=2,

y=-4+8=

4

Therefore, we derive our second solution:

<h2><u><em>x=2</em></u></h2><h2><u><em>y=4</em></u></h2>

<u><em></em></u>
