can someone help me solve this?​

Answer:

6 times

Step-by-step explanation:

you divide 3.00 by 0.50

Answer:

the value of x is 68

Step-by-step explanation:

because the line does change on either of the sides so that makes x the same value as the other side which is 68. forgive me if im wrong.

Answer:

D

Step-by-step explanation:

out of the choices

A) 2x-y=-2

3x+2y=-10

B) x+4y=3

2x+5y=3

C) 2x+3y=5

x-4y=-14

D) 3x+4y=15

x+y=5

only the system in D has a solution of x=5 and y=0

solve by substitution x+y=5 so x=5-y

plug into the other equation so 3(5-y)+4y=15

distribute 15-3y+4y=15 then minus 15 on both sides and combine like terms

so y=0 then put that value back into the other equation

so x+y=5 equals x+0=5 so x=5 this means the solution to the system of equations is the point (5,0)

Hope this helps! :)

Answer:

Substitute f(x)=0

0=5-4x over 15 multiply both sides

0=75-4x move the variable to the left

4x=75 divide both sides

solution x=75 over 4

alternate form is x=18 3 over 4, x=18.75

Answer:

1. k + 2 (or other way around, it doesn't matter)

2. PY or P×Y

3. 10 - z

Step-by-step explanation:

1. You are adding here, so you add the two terms together.

2. If we had the amount of rulers and how much they cost, we could multiply to find these. Since we don't, we just leave the two variables to be multiplied.

3. It is asking the difference between two numbers, meaning that you need to subtract. With these types of problems, you always use the first number that appears in the problem to start the expression. For instance, if it had listed z first, then you would have done z - 10.

Answer:

p(t) = 0 for t = 1

p(t) = 1 for t = 1/8 = 8^-1

Step-by-step explanation:

the graph you will have to do yourself.

just go there and type in

[tex] - log_{8}(x) [/tex]

well, don't type "log" in letters.

you start by typing the "-" sign, and then you need to look up the functions by clicking on the "funcs" button and look for the log functions .

pick the

[tex] log_{a}[/tex]

option. and then simply enter 8 as the first parameter in the {} brackets and x as the second in the () brackets.

and then you see.

any logarithm is 0 for x (or t) = 1.

because any a⁰ = 1.

and the logarithm gives you that exponent of the base number that leads to the given x value.

in other words : a logarithm is the inverse function of an exponential function.

the exponential function is

y = a^x

and the logarithm then determines

[tex]x = log_{a}(y) [/tex]

that is all.

and

[tex] - log_{8}(x) = 1[/tex]

means that the logarithm itself delivered -1.

and 8^-1 = 1/8

so, p(t) = 1 for t = 1/8

Step-by-step explanation:

g(f(x)) = f(x) substituted in g(x)'s function.

g(3x^2 - x - 8) = 3x^2 - x - 8 + 5 = 3x^2 - x - 3.

Answer:

B 9, -9

Step-by-step explanation:

x^2 - 81 = 0

Add 81 to each side

x^2 = 81

Take the square root of each side

sqrt(x^2) = sqrt(81)

x = ±9

Answer : 4/7

Here it's given that Brad's family travelled 2/7 of the total distance to his uncle's house on Saturday . So if we assume the total distance to be 1 , then the remaining distance will be ,

[tex]\sf\longrightarrow 1 - \dfrac{2}{7}=\dfrac{7-2}{7}=\boxed{\dfrac{5}{7}}[/tex]

Again it's given that they travelled 4/5 of the remaining distance on Sunday . So , the distance travelled would be ,

[tex]\sf\longrightarrow \dfrac{4}{5}\times \dfrac{5}{7}=\boxed{\sf \dfrac{4}{7}} [/tex]

Therefore Brad's family travelled 4/7 of the total distance on Sunday .

To find total cookies sold add each kind of cookie together.

590

Step-by-step explanation:

You must add the two numbers.

320 + 270 = 590

Answer:

Adult tickets sold = 225

Student tickets sold = 283

Step-by-step explanation:

Let A = total adult tickets sold

Let S = total student tickets sold

If a total of 508 tickets were sold, then  A + S = 508

If there were 58 more student tickets than adult tickets sold, then

S = A + 58

Substitute S = A + 58  into A + S = 508 to find S:

A + (A + 58) = 508

2A + 58 = 508

2A = 508 - 58 = 450

A = 450 ÷ 2 = 225

If A = 225,  then using  S = A + 58,  find S:

S = 225 + 58 = 283

Adult tickets sold = 225

Student tickets sold = 283

The area of the polygon JKLMNO is 68.5 square units

The coordinates of the triangle are:

M = (-1, -5)

N = (-8, -6)

O = (-5, -2)

Calculate the base and the height of the triangle using:

[tex]d = \sqrt{(y_2 -y_1)^2 +(x_2 -x_1)^2[/tex]

So, we have:

[tex]ON = \sqrt{(-5+ 8)^2 +(-2 + 6)^2[/tex]

ON = 5

[tex]OM = \sqrt{(-5+ 1)^2 +(-2 + 5)^2[/tex]

OM = 5

The area is:

Area = 0.5 * ON * OM

This gives

Area = 0.5 * 5 * 5

Evaluate

Area = 12.5

Hence, the area of the triangle MNO is 12.5 square units

The coordinates of the rectangle are:

J = (1, 6)

L = (5, 3)

M = (-1, -5)

O = (-5, -2)

Calculate the length and the width of the rectangle using:

[tex]d = \sqrt{(y_2 -y_1)^2 +(x_2 -x_1)^2[/tex]

So, we have:

[tex]OM = \sqrt{(-5+ 1)^2 +(-2 + 5)^2[/tex]

OM = 5

[tex]ML = \sqrt{(-1 - 5)^2 + (-5 - 3)^2[/tex]

ML = 10

The perimeter is:

Perimeter = 2 * (OM + ML)

This gives

Perimeter = 2 * (5 + 10)

Evaluate

Perimeter = 30

Hence, the perimeter of the rectangle JLMO is 30 units

In (a), we have:

The area of the triangle MNO is 12.5 square units

The area of the rectangle JKMO is:

Area = OM * ML

This gives

Area = 5 * 10 = 50

The coordinates of triangle JKL are:

J = (1, 6)

K = (5, 6)

L = (5, 3)

Calculate the base and the height of the triangle using:

[tex]d = \sqrt{(y_2 -y_1)^2 +(x_2 -x_1)^2[/tex]

So, we have:

[tex]KL = \sqrt{(5- 5)^2 +(3 - 6)^2[/tex]

KL = 3

[tex]JK = \sqrt{(1- 5)^2 +(6 - 6)^2[/tex]

JK = 4

The area of JKL is

Area = 0.5 * KL * JK

This gives

Area = 0.5 * 3 * 4

Area = 6

Add the three areas

Total area = 6 + 12.5 + 50

Evaluate

Total area = 68.5

Hence, the area of the polygon JKLMNO is 68.5 square units
