Answer:

-1

Step-by-step explanation:

-isolate everything  with x on one side and without x on the other side

-remember if you pass the equal sign change the sign of that term

13x+8x+9x = -22-8

-combine like terms

30x = -30

-divide both sides by 30

x= -1

Answer:

x = -1

Step-by-step explanation:

simplfy to 21x + 8 = -9x -22

add 9x  to get 30x + 8 = -22

then subtract 8 to get 30x =-30

divide by 30 and you get x = -1

Answer:

Q1:  20,000 envelopes

Q2: Savings = $700

Step-by-step explanation:

Let the number of envelopes stuffed by each be "x"

We can create 2 equations, each for Anna and Jason, equate them and find our answer.

For Anna:

$14 for 400, so

14/400 = $0.035 PER ENVELOPE

Savings for Anna is  0.035x

For Jason:

Already has 100 (fixed)

Gets $9 for 300 envelopes, so

9/300 = $0.03 PER ENVELOPE

Savings for Jason is  100 + 0.03x

We equate and solve for x:

So, For both their savings to be equal, they need to stuff 20,000 envelopes

Their savings would be:

0.035x

or 100 + 0.03x

We can plug in x = 20,000 in any one equation, the answer would be same.

So,

0.035(20,000) = $700

savings = $700

Step-by-step explanation:

2.2lb = 1 kg

6.6/2.2=3.0kg

The correct weight of the baby is given by option B) 3.0 kg

The unitary method is a method in which you find the value of a unit and then the value of a required number of units.

Given here, the baby's weight as 6.6 lbs and 1 lb=0.45 kg

Thus 6.6 lbs=6.6×0.45

                     = 3.0 ( approx)

Hence, The correct weight of the baby is given by option B) 3.0 kg

Answer: I think it is f(x)=1/(x-4)

Step-by-step explanation:

By taking f(x), and applying a left or right and/or up or down transformations to it, the function could be written using the equation f(x-h)+k.

Doing so will make the graph of the function move h units to the left or right. (Positive or negative) (make sure the operation before the h is subtraction when determining the sign of h)

Also, when finding k (up and down) (positive or negative) apply this function.

f(x)=(x-h)+k

As a result, plug in your right 4 units as h, and since you are not needing to move up or down k would be 0. So, f(x)=1/(x-(4))+0 or simplified, f(x)=1/(x-4)

Answer:

F(x)=1/x-4

Step-by-step explanation: I solve the problem by solving this equation below.

Answer:

Step-by-step explanation:

Given expression is (3x²y⁴)²

We can rewrite the given expression as,

(3x²y⁴)² = (3)²(x²)²(y⁴)² [Every term of the the expression will be squared]

            = 9x⁴y⁸

But in the picture attached, it has been given as (6x⁴y⁸).

Therefore, in place of 6 it should be 9.

Add sides 74

Answer:

x = [tex]\frac{127}{11}[/tex]

Step-by-step explanation:

14x - 76 + 8x + 2 = 180

Collect like terms;

22x - 74 = 180

Add 74 to both sides;

22x = 254

Divide both sides by 22;

x = [tex]\frac{254}{22}=\frac{127}{11}[/tex]

Answer:

[tex]xy=wz[/tex]

Step-by-step explanation:

Given that:

Speed of Wilmer up the hill = [tex]y[/tex] km/min

Time taken up the hill = [tex]x[/tex] minutes

Speed of Wilmer down the hill = [tex]z[/tex]  km/min

Time taken up the hill = [tex]w[/tex] minutes

Distance can be calculated by multiplying the Speed with Time i.e.

The formula for distance is given as:

[tex]Distance = Speed \times Time[/tex]

Distance up the hill = [tex]y\times x =xy\ kilometers[/tex]

Distance down the hill = [tex]z\times w =wz\ kilometers[/tex]

It is well known that, the distance up the hill and down the hill will be same.

Putting both the values equal, we get:

[tex]xy=wz[/tex]

Answer:

x= 1.5 $

Step-by-step explanation:

Hi there,

This is a tough question. Let us find out how to tackle it.

From the problem, we see that we 'll have to find x to figure out how much each type is. The only real number of money we get is 10.50$ - the amount the shopper spent. Let's divide this money into respective parts:

He bought 1 pound of apple => the cost of all the apple he bought is 1 ( pound) × (2x) ($ per pound) = 2x $

Do the same with Grapes and Oranges, we can easily see that he spent 6x-5 $ on grapes, x+2 $ on oranges.

The total amount he spent 10.50$ is now equal to (2x) + (6x-5) + (x+2).

Next we can change this equation, just so we find x easier:

10.50$ = (2x) + (6x-5) + (x+2)

10.50$ = 2x + 6x + x + 2 - 5

10.50$= 9x - 3

13.50$= 9x

x= 1.50 $

Thus, we can now calculate the price of each type. Apples are 3$ per pound, grapes are 4$ per pound, oranges are 3.50$ per pound.

HOPE YOU'LL LEARM WITH JOY AND GOOD GRADE

Answer:

Shopper spend on Apples $3 , on Grapes $4  and  on Oranges $3.5

Step-by-step explanation:

We are given:

Apples: $(2x) per pound

Grapes: $(6x - 5) per pound

Oranges: $(x + 2) per pound

A shopper purchases one pound each of  apples, grapes, and oranges and spends  $10.50.

It can be written as: [tex]2x+6x-5+x+2=10.50[/tex]

We need to find how much the shopper spend on each fruit.

Solution:

Now, we need to find value of x by solving equation

[tex]2x+6x-5+x+2=10.50[/tex]

Solving:

[tex]2x+6x+x+2-5=10.50\\9x-3=10.50\\9x=10.50+3\\9x=13.5\\x=\frac{13.5}{9}\\x=1.5[/tex]

The value of x is: x=1.5

Now finding cost of one pound each fruit by putting x=1.5

Apples: $(2x) per pound  

$2x= 2(1.5) = $3

Grapes: $(6x - 5) per pound

$(6x-5) = (6(1.5)-5)= $4

Oranges: $(x + 2) per pound

$(x+2)=(1.5+2)=$3.5

So, shopper spend on apples $3, on Grapes $4 and on Oranges $3.5.

Answer:

i think ur in a higher grade then me but im good w/ equations so OoOO0p

Step-by-step explanation:

equation: y = x - 6 + x^2

(6,0) (7,1) (8,4) (9,9)

I figured this out by looking at the point (6,0). To get 0 (y), you have to subtract 6. Knowing this, I subtracted 6 from the rest of the coordinates, leaving me with numbers that are able to be squared to get y. This led me to the equation x - 6 + x^2.
