Answer:

X=5

Step-by-step explanation:

(step 1) 2 - 3x = -x - 8

-3x + 2 = -x -8

(step 2)

-3x + 2 = -x - 8

-3 + 2 - 2 = -x -8 -2

(step 3)

-3x =  -x- 10

(step 4)

-3 + x = -x -10 +x

(step 5)

-2x = -10

Answer

x = 5

Answer:

15 students

Step-by-step explanation:

from the algebra = 24 - 10 = 14

from the draft = 11 - 10 = 1

14 + 1 = 15

the total students that are taking algebra or drafting but not both is 15 students

Answer:

algebra:34 drafting:21 (use only one answer)

10 + 11 = 21 for drafting

Answer:

18x-16

Step-by-step explanation:

expression: (11x-8)+7(x-1)

ok so what you want to do is combine like terms

but first you are going to distribute

(11x-8)+(7x-8) you distribute the 7

they you can subtract 8 from -8 and that will give you -16

you will then add 11x and 7x which will get you 18x

the final expression will be 18x-16

Answer: w=5 , L= 2+2(5)=12

Step-by-step explanation:

L=2+2W

A= 60

LxW=60, now we will replace the L

(2+2W)(W)=60   we multiply

2w^2+2w=60

2w^2+2w-60=0  we divide by 2 the equation so we can work easier

w^2+w-30=0

find out w using the quadratic equation

we will get 2 solution,

w=5 and another solution is -6, which is not valid, as the side can not be negative

Answer:

The standard form of this hyperbola is [tex]\frac{(x-3)^{2}}{5}-\frac{(y+1)^{2}}{9} = 1[/tex].

Step-by-step explanation:

From Analytical Geometry, the standard form of the hyperbola is defined by the following expression:

[tex]\frac{(x-h)^{2}}{a^{2}}-\frac{(y-k)^{2}}{b^{2}} = 1[/tex] (1)

Where:

[tex]x[/tex] - Independent variable, dimensionless.

[tex]y[/tex] - Dependent variable, dimensionless.

[tex]a, b[/tex] - Semiaxis lengths, dimensionless.

[tex]h, k[/tex] - Coordinates of the center, dimensionless.

Let the hyperbola be defined by [tex]9\cdot x^{2}-5\cdot y^{2}-54\cdot x -10\cdot y +31=0[/tex], we proceed to derive the standard form by algebraic means:

1)  [tex]9\cdot x^{2}-5\cdot y^{2}-54\cdot x -10\cdot y +31=0[/tex] Given

2) [tex](9\cdot x^{2}-54\cdot x)+(-1) \cdot (5\cdot y^{2}+10\cdot y)+31 = 0[/tex] Commutative and associative properties/[tex](-1)\cdot a = -a[/tex]

3) [tex](9\cdot x^{2}-54\cdot x + 81)+(-81)+(-1)\cdot (5\cdot y^{2}+10\cdot y +5)+(-1)\cdot (-5)+31 = 0[/tex] Modulative, distributive and associative properties/[tex](-1)\cdot a = -a[/tex]/Existence of the additive inverse

4) [tex](3\cdot x-9)^{2}+(-1)\cdot (\sqrt{5}\cdot y +\sqrt{5})^{2}+(-81)+5+31 = 0[/tex] Perfect trinomial square/[tex](-a)\cdot (-b) = a\cdot b[/tex]/Commutative property

5) [tex]9\cdot (x-3)^{2}+(-1)\cdot (5) \cdot (y+1)^{2}-45 = 0[/tex] Distributive property/[tex](a\cdot b)^{c} = a^{c}\cdot b^{c}[/tex]/Definition of addition and subtraction.

6) [tex]9\cdot (x-3)^{2}-5\cdot (y+1)^{2}= 45[/tex]    [tex](-1)\cdot a = -a[/tex]/Compatibility with addition/Existence of additive inverse/Modulative property.

7)  [tex]\frac{(x-3)^{2}}{5}-\frac{(y+1)^{2}}{9} = 1[/tex] Compatibility with multiplication/Definition of division/Distributive property/Result.

The standard form of this hyperbola is [tex]\frac{(x-3)^{2}}{5}-\frac{(y+1)^{2}}{9} = 1[/tex].

Answer:

y = (-5/2)x + 1

Step-by-step explanation:

We can see that the line intersects (0,1) and (2, -4). We use these points to find the slope: m = (-4-1)/(2-0) = -5/2. Also, the y-intercept is (0,1), so b = 1. Substituting these values into y=mx +b, we get y = (-5/2)x + 1.

Answer:

x=-3

Step-by-step explanation:

[tex]\sqrt{x+7}-x=5\\\sqrt{x+7}=5+x\\x+7=x^2+10x+25\\x^2+9x-18=0\\(x+3)(x+6)=0\\x=-3, x=-6\\\sqrt{-3+7}-(-3)=5\\\sqrt{-6+7}-(-6)=7=5[/tex]

x=-6 is extraneous because 7 does not equal to 5

x=-3 is the answer because 5=5

Answer:

passive income

Step-by-step explanation:

Answer:

There were 8 more silver coins than gold coins in the jar.

Step-by-step explanation:

Given that:

Total coins in the jar = 80 coins

Gold coins = 25% of total coins

Number of gold coins = [tex]\frac{25}{100}*80[/tex]

Number of gold coins = 20

Silver coins = 35% of total

Number of silver coins = [tex]\frac{35}{100}*80[/tex]

Number of silver coins = 28

Copper coins = 40% of total

Number of copper coins = [tex]\frac{40}{100}*80=32[/tex]

Difference between silver and gold coins = No. of silver coins - No. of gold coins

Difference = 28-20 = 8

Hence,

There were 8 more silver coins than gold coins in the jar.

Answer:

3x³ - 8x² - 7x + 12

Step-by-step explanation:

We multiply these terms, (so expand the brackets). Referring to the diagram attached, we multiply the first terms, outer terms, inner terms, and last terms.

Let's first look at the first two (we will do something about the third brackets later):

(3x+4)(x-1)

Firsts:

3x²

Outer:

-3x

Inner:

4x

Last:

-4

Now we combine:

3x² - 3x + 4x - 4

= 3x² + x - 4

So from the whole equation, we now have this:

(3x² + x - 4)(x - 3)

We do a similar thing here.

3x³ - 9x² + x² - 3x - 4x + 12

Simplify:

3x³ - 8x² - 7x + 12

Answer:

The total cost of the ski hat and the ski boots is $112.35.

Step-by-step explanation:

First, we need to add the prices of the ski hat and the ski boots.

85.50 + 19.50 = $105

Now, we need to find 7% of $105, and then add it to the total.

105 x 0.07 = $7.35

105 + 7.35 = $112.35

Therefore, the total cost of the ski hat and the ski boots is $112.35.
