Answer:

( [tex]\frac{1}{2}[/tex], 0 )

Step-by-step explanation:

Given the 2 equations

4x + 3y = 2 → (1)

2x - 3y = 1 → (2)

Adding (1) and (2) term by term will eliminate the y- term, that is

6x = 3 ( divide both sides by 6 )

x = [tex]\frac{3}{6}[/tex] = [tex]\frac{1}{2}[/tex]

Substitute x = [tex]\frac{1}{2}[/tex] into either of the 2 equations and evaluate for y

Substituting into (1)

4([tex]\frac{1}{2}[/tex] ) + 3y = 2

2 + 3y = 2 ( subtract 2 from both sides )

3y = 0 ⇒ y = 0

Solution is ( [tex]\frac{1}{2}[/tex], 0 )

Answer:

x=-5

Step-by-step explanation:

-6(x + 7)=-12

-6x+-42=-12

-6x=30

x=-5

Answer:

X = -5

Step-by-step explanation:

-6(x+7)=-12

Use the distributive property

-6x-42=-12

Add 42 to -42, and 42 to -12

Adding 42 to -42 cancels -42 out

-6x=30

Divide -6 by -6, and 30 by -6

x=-5

Answer:

Step-by-step explanation:

AC = 150  Feet

CB = 75 feet.

BD = 100 feet

You use the tangent here.

Tan(A) = opposite/ Adjacent

Opposite = BD = 100 feet

Adjacent = AB = AC + CB = 150 + 75 = 225  feet.

Tan(A) = 100 / 225

Tan(A) = 0.4444

A = Tan-1(0.4444)

A = 23.96 degrees, but the front row of trees cannot be more than 100 feet tall

Answer:

Sylvia's cat weighs 3 pounds more than Michelle's cat

Sylvia’s cat weighs 48 ounces more than Michele’s cat.

The downward force exerted by any object due to the effect of the earth's gravity is called weight.

Given that:-

The difference between the weight = 12 - 9 = 3 pound

1  pound = 16 ounces

3 pounds = 16 x 3 ounces = 48 ounces

Therefore Sylvia’s cat weighs 48 ounces more than Michele’s cat.

let's recall that for a function f(x) that has an inverse function f⁻¹(x), the domain of f(x) corresponds to the range of f⁻¹(x), what the heck does that all mean?

well, it means that for any coordinate pairs (a , b) in f(x), there's a corresponding pair of (b , a) on f⁻¹(x).

we know in this case that f(-4) = 15, or namely that f(x) has a pair of (-4 , 15), well, that means that f⁻¹(x) has a swapped pair of (15 , -4).

the above means that f⁻¹(15) = -4.

Answer:

(C) The price was reduced by a quarter

(H) The price is 75% of what it was before.

Step-by-step explanation:

Let's go through all the answer choices:

(A) The price doubled.

(B) The price is 150% of the price before.

(E) The price is now 1.5 times greater than what it was before.

(F) The price now is 662 % of what it was before.

(G) The price now is 200% of what it was before.

knowing that decreased meaning smaller or fewer.

Thus, it can't be doubled or more than 100% as well was greater.

Hence, the best answer is

(C) The price was reduced by a quarter

(H) The price is 75% of what it was before.

Note:

Reduced = Smaller, Less amount

Greater = More

Doubled = More

Decreased = Smaller, Less amount.

The statements are equivalent to the statement "the price decreased by 25%" are:

The price was reduced by a quarter.

The price is 75% of what it was before.

We have statement,

So, the statement that follow the statement is

The price was reduced by a quarter.

The price is 75% of what it was before.

Statements are not equivalent to the given statement.

"The price is 150% of the price before" means the price increased by 50%, not by 100% or double.

Answer:

140 squirrels

Step-by-step explanation:

first week, there are 5 squirrels.

second week, there are 8 squirrels.

third week, there are 11 squirrels.

let's calculate the amount of squirrels at the end of 28 weeks. from the statement given, an addition of 3 squirrels for every week.

by cross multiply method:

5 squirrels = 1 week

x squirrels = 28 weeks

x = 28 x 5

x = 140 squirrels.

so you will have an amount of 140 squirrels after 28 weeks.

Answer:

x = -1/6

Step-by-step explanation:

Firstly, you need to expand the brackets. So this would give, 8 + 12x - 6.

Then you collect like terms to give, 12x + 2. After this, we solve for x. To do this we need to assume that all this is = 0. Then it's easy to solve:

12x + 2 = 0

12x = -2

x = -2/12

x = -1/6

Step-by-step explanation:

Where are your answers?

Answer:

Ok, suppose that there are M Petri dishes, where M is an integer number.

If there are N students in the class, then the number of Petri dishes that each student gets is:

# = M/N.

(always that N divides M)

If not, we will have a remainder, R,  of Petri dishes such that:

M ≥ N

R < N

This means that:

The total number of Petri dishes must be equal or larger than the number of students.

If M is larger than N, and N does not divide M, then the remainder of the quotient will be smaller than N.

Now with this, you can replace the numbers and do the math.

"The more students that decide to do the bacteria experiment, the fewer the number of Petri dishes each student gets."

You can easily see this because the equation for the number of Petri dishes that each student gets is:

# = M/N.

Here, N is in the denominator, then if the number of students in the class increases, the denominator in the operation increases, which means that the quotient will be smaller.

we can see that the triangle is isosceles since it has 2 equal sides

so that means 2 equal angles then :

x + 17 = 4x - 34

3x = 51

x = 17

or

the sum of 3 triangles angles = 180

6x + 10 + x + 17 + 4x - 34 = 180

11x = 187

Answer:

  65.8 ft

Step-by-step explanation:

The number of strings required to tie each vertex to the other three will be ...

  (4)(3)/2 = 6

Those strings will be perimeter strings plus two diagonal strings. The lengths of the perimeter strings are given as 12 ft and 7 ft. The lengths of the diagonal strings can be found using the Pythagorean theorem.

  d² = 12² +7² = 144 +49 = 193

  d = √193 ≈ 13.892

Then the total length of all strings is ...

  L = 2(12.0 +7.0 +13.9) = 65.8 . . . . feet

The artist will need 65.8 feet of string.

The volume of the right prism is the product of the length, width and height

The height of the prism is 7.40 ft

The given parameters are:

Volume = 214.5 ft cube

Length = 5 ft

Width = 5.8 ft

The volume of the right prism is calculated as:

Volume = Length * Width * Height

So, we have:

214.5 = 5 * 5.8 * Height

Evaluate the product

214.5 = 29 * Height

Divide both sides by 29

7.40 = Height

Rewrite as:

Height = 7.40

Hence, the height of the prism is 7.40 ft

Ok, so when you need to know f(4) you plug in 4 for x

f(4)=2(4)-10

Hi! Hope you're enjoying your day!

In order to solve this, all we have to do is plug in the value of x.

So we're given that

f(x)=2x-10

So f of x is equal to 2 times x minus 10.

Thus

f of 4 is equal to 2 times 4 minus 10 (it can be simplified, right?) :)

f(4)=8-10

f(4)=-2

The cost of a utility for a pole with a diameter of 41 cm and a height of 780 cm is $3894697.41

The density formula is given by:

Density = mass/volume

The volume of the cylinder = π * radius² * height

Radius = diameter / 2 = 41/2 = 20.5, height = 780 cm. Hence:

Volume = π * 20.5² * 780 = 1029798 cm³

Density = mass/volume

6.1 = mass/1029798

mass = 6281770 kg

Cost = 6281770 kg * $0.62 per kilogram = $3894697.41

The equation of the line will be x = 6. And the slope of the vertical line is infinite.

A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.

The linear equation is given as,

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

The equation of the vertical line is given as,

x = c

The line is passing through (6, 0). Then we have

6 = c

Then the equation of the line will be x = 6. And the slope of the vertical line is infinite.
