Answer:

x = -8

Step-by-step explanation:

2 - (3x + 5) = 5 - 2x

Subtract 2 from each side.

-(3x + 5) = 3 - 2x

Apply the negative sign in front of the parentheses.

-3x - 5 = 3 - 2x

Add 5 to both sides.

-3x = 8 - 2x

Add 2x to both sides.

-x = 8

We can't have a negative x value, so we'll need to multiply each side by -1.

x = -8

Hopefully, this helped and wasn't too confusing!

Answer:

Solution given;

2-(3x+5)=5-2x

2-3x-5=5-2x

-3-5=3x-2x

x=-8 is your answer

Answer:

576

Step-by-step explanation:

f(2) = 4f(1) = 4*9 = 36

f(3) = 4f(2) = 4 * 36 = 144

f(3) = 4f(3) = 4 * 144 = 576

Answer:

x=4, x= -1

Step-by-step explanation:

Write your problem:

[tex]x^{2}[/tex] - 4 = 3x

Subtract 3x from both sides:

[tex]x^{2}[/tex] - 4 - 3x = 3x - 3x

Simplify:

[tex]x^{2}[/tex] - 3x - 4 = 0

Answer:

x^2 - 6x + 9

Step-by-step explanation:

(x-3)^2

(x-3)(x-3)

x^2 -3x -3x + 9

x^2 - 6x + 9

^2 means (x - 3) times itself twice.

(x - 3)(x - 3)             multiplying polynomials- Firsts, Outs, Inners, Lasts (FOIL)

                                 Firsts (x* x)   Outs (x*-3)   Inners (-3 * x)   Lasts (-3*-3)

xx -3x -3x +9            Combine like terms.

      -3x -3x             Adding/subtracting integers- same signs means you add          

                                     and keep the sign.

x^2 -6x + 9

Answer:

x=1 and y= 5[tex]\frac{1}{4}[/tex]

Step-by-step explanation:

To solve this, lets take the first equation and find the x value.

Because it is ordered in standard form, we need to convert to slope-intercept form, and isolate the y.

5x+4y=16

-5x       -5x

4y=-5x+16

÷4   ÷4  ÷4

y=[tex]\frac{-5}{4}[/tex]+4

or

y=-1[tex]\frac{1}{4}[/tex]+4

or

y= 5[tex]\frac{1}{4}[/tex]

Now that we have the y value, we can use this to find the x value by inserting it into either equation, since they both have y values in them. Going with the first one again, lets try it:

5x+4([tex]\frac{-5}{4}[/tex]+4)=16

5x-5+16=16

5x+11=16

    -11 -11

5x=5

÷5 ÷5

x=1 and y= 5[tex]\frac{1}{4}[/tex]

Answer:

.30

Step-by-step explanation:

Step-by-step explanation:

We know to find the area of a rectangle we need to multiply the length times the height.

In other words,

[tex]a = l \times w[/tex]

We know our length is 75 and our height is 55, so lets multiply it.

[tex]75 \times 55 = 4125[/tex]

So our final answer is:

4125 sq. ft

Answer: 14

Step-by-step explanation:

Fraction of blue shirts = 2/5

Fraction of red shirts = 3/10

Number of shirts in the shipment = 20

The number of shirts that are either blue or red will be:

= (2/5 + 3/10) × 20

= (4/10 + 3/10) × 20

= 7/10 × 20

= 14

The number of shirts that are either blue or red is 14

Answer:

Step-by-step explanation:

A = length * width

Length = A ÷ width

           [tex]= \frac{64x^{2}y}{16xy}\\\\= 4*x^{2-1}*y^{1-1}\\\\= 4x^{1}*y^{0}\\\\= 4x*1\\=4x[/tex]

Answer:

I think its gon be 24 guests

Answer:

24 people can be there at most :)

Step-by-step explanation:

$32 divided by 16(guests) is $2

so its $2 per person

so 48$ divided by $2 is 24

So Camille can invite 24 people at the cost of 48$ being her total at most :)

Answer:

Greatest common factor of 17

So, the prime factors of 45 are 3, 3, and 5. The Greatest Common Factor is the greatest number that is common (that is, in both lists). It is 17. Since 17 is a factor of itself and of 51 -- which is 3 x 17 -- then the greatest possible common factor is 17!

Step-by-step explanation:

Add and subtract the second term to the expression and factor by grouping.

- (m - 1 )( 7m + 17 )

Find the gradient first

m = (y2-y1)/(x2-x1) = 3-(-1)/2 - (-2) = 4/4 = 1

then find the equation of the... slope ._.

y - y1 = m(x - x1)

y - (-2) = 1(x - 3)

y + 2 = x - 3

y =x -3 - 2

y = x - 5

So the equation is y = x - 5

Answer:

AB = 51

BC = 50

AC = 42

PQ = 42

QR = 42

PR = 59

Step-by-step explanation:

Perimeter of ∆ ABC = Perimeter of ∆ PQR

3x + 9 + 3x + 8 + 3x = 3x + 3x + 4x + 3

9x + 17 = 10x + 3

17 - 3 = 10x - 9x

14 = x

.: x = 14

AB = 3x +9 = 3×14+9 = 42+9 = 51

BC = 3x +8 = 3×14+8 = 42+8 = 50

AC = 3x = 3×14 = 42

PQ = 3x = 3×14 = 42

QR = 3x = 3×14 = 42

PR = 4x +3 = 4×14+3 = 56+3 = 59

Angle 1 and 2 are equal because of correspondence angle

so , (78-2x) = (89-3x)

x = 89 - 78

x = 11

hence angle 1 = ( 78 - 2*11) = 56

and angle 2 = ( 89-3*11) = 56

So, both of angle is 56

Step-by-step explanation:

y=x+7........eqni

y=6x+2.....eqnii

putting the value of x in eqnii

y=6x+2

or, x+7=6x+2

or, 7-2=6x-x

or 5= 5x

hence,x=1

sbstutuung the value of x in eqni,

y= x+7

=1+7

=8

hence the value of y is 8
