Is (3, -5) a solution to this system of equations?

y = -1/3x - 4
y = -2x + 1

Yes or No

Answers

Answer 1

Answer: Yes

Step-by-step explanation:

Solve the system of equations by setting the two substituting the first y equation in for the second and getting: -1/3x - 4 = -2x + 1.

Now, add 2x to the left side to cancel it from the right and add 4 to the right side to cancel if from the left to get: (5/3)x = 5

Solve for x to get 3.

Plug x into the second equation (could be either equation though) and get: y = -2(3) = 1 = -5.

Thus, (3,-5) is a solution :)

Answers

Answer:

Step-by-step explanation:

General equation of a circle : [tex](x-h)^2+(y-k)^2=r^2[/tex]

where (h,k) is at center and r = radius

Here, we want to find the equation of a circle with a given center at (3,4) and a given radius of 6

This is very simple, all we have to do is assign variables and then plug in the values of the variables into the general equation of a circle

First lets assign variables.

(h,k) is center and the circle has a given center at (3,4)

so (h,k) = (3,4) thus, h = 3 and k = 4

r = radius and the circle has a given radius of 6 so r = 6

now we plug this into the general equation of a circle.

recall equation : (x-h)² + (y-k)² = r²

h = 3, k = 4 and r = 6

plug in values

(x-3)² + (y-4)² = 6²

simplify exponent

(x-3)² + (y-4)² = 36

and we are done!

Find the missing side of the triangle.

[tex]\Large\maltese\underline{\textsf{B. This problem has been solved!}}[/tex]

We should find the leg of this right triangle, not the hypotenuse.

The hypotenuse, the longest side, is already given to us.

We can find it using Pythagoras' Theorem:

[tex]\Large\textbf{$a^2+b^2=c^2$}[/tex].

We know b and c, we need to find a.

[tex]\bf{a^2+9^2=15^2}[/tex] | square

[tex]\bf{a^2+81=225}[/tex] | subtract 81

[tex]\bf{a^2=144}[/tex] | square-root both sides

[tex]\bf{a=\pm12}[/tex]

And we should automatically cross out this extraneous solution of "a=-12", because side lengths can't be negative!

Answers

4.5 litres of fruit punch with 0.5 litres of water.
13.5 /4.5 = 3. Multiply 0.5 by 3 to get 1.5 litres of water. Therefore, 13.5 litres of fruit punch concentrate needs 1.5 litres of water. 13.5 + 1.5 = 15 litres of fruit punch in total.

Find the area of the regular polygon with the given radius or apothem

Answers

Answer:

  50 cm²

Step-by-step explanation:

Given that the regular polygon is a square, there are multiple ways you can jump directly to the answer. Perhaps the simplest is to use the formula for the area of a rhombus:

  A = 1/2(d1)(d2)

where d1 and d2 are the lengths of the diagonals. Here, we see that half the diagonal is 5 cm, so the area is ...

  A = (1/2)(10 cm)(10 cm) = 50 cm² . . . . area of the polygon

__

Alternate solution

If you want to use the radius and the number of sides in a formula, you can consider the area of each triangle formed by radii and a side. That triangle has area ...

  A = 1/2r²sin(α)

where r is the radius and α is the central angle. For an n-sided polygon, the area is the sum of n of these triangles, and the central angle is 360°/n. Then the polygon area is ...

  A = n/2·r²·sin(360°/n)

For n = 4 and r = 5 cm, the area is ...

  A = (4/2)(5 cm)²(sin(360°/4)) = 2(5 cm)²(1) = 50 cm² . . . . area of square

_____

Additional comment

The formula is somewhat different if you start with the length of the apothem. One way to find the area is using the above formula and the relation between the radius and apothem:

  r = a·sec(180°/n)

Another formula uses the apothem directly:

  A = n·a²·tan(180°/n)

Find the sixth term of the geometric sequence when a4=−8 and r=0.5
A. 4
B. 2
C. -4
D. -2

Answers

Answer:

D

Step-by-step explanation:

to find a term in the sequence multiply the previous term by r , then

a₄ = - 8 , so

a₅ = - 8 × 0.5 = - 4

a₆ = - 4 × 0.5 = - 2

The sixth term of the sequence will be negative 2. Then the correct option is D.

What is a geometric sequence?

Let a₁ be the first term and r be the common ratio.

Then the nth term of the geometric sequence is given as,

aₙ = a₁ · (r)ⁿ⁻¹

The fourth term (a₄) is negative 8 and the common ratio is 0.5.

Then the sixth term will be

For n = 5, we have

a₅ = a₁ · (r)⁵⁻¹

a₅ = a₁ · (r)⁴

a₅ = a₁ · r³ · r

a₅ = a₄ · r

a₅ = -8 · 0.5

a₅ = -4

Then the sixth term of the sequence will be

a₆ = a₁ · (r)⁶⁻¹

a₆ = a₁ · (r)⁵

a₆ = a₁ · r⁴ · r

a₆ = a₅ · r

a₆ = -4 · 0.5

a₆ = -2

The sixth term of the sequence will be negative 2.

Then the correct option is D.

2. You bought 8 bags of gummy bears and they cost $2.79 each. How much did
the gummy bears cost after you included the 8% sales tax?
Your answer

Answers

it would be $25.52, i’m pretty sure this is right, i’m sorry if it isn’t!!

Answer:

$24.11

Step-by-step explanation:

Find the total price of the gummy bears by multiplying the 2.79 each bag by the 8 bags. 2.79×8=22.32.Convert the percentage into a decimal. Move the decimal place that is after the 8% (same as 8.0% if you need to visualize the location of the decimal) to 2 places to the left. This means your decimal is 0.08.Multiply the decimal by the total untaxed cost from the first step. This will give you the tax. 22.32×0.08=1.7856, which rounds to currency of 1.79. Add the tax and the untaxed total together to get the grand total. 1.79+22.32=24.11Your answer is $24.11
