Explicação passo a passo:

Dado que :

Hora definida pela mãe = 20h00

Número de horas além do tempo definido = 2 horas e 30 minutos

Hora em que ela voltou para casa:

(tempo definido pela mãe + número de horas além do tempo definido)

(20h + 2 horas e 30 minutos) = 22h30

Answer: $4.80

Step-by-step explanation: 24 * 0.20 = 4.80

Step-by-step explanation:

First we solve it.

I'll use substitution.

In the first equation y equals -2x+2 so we can apply that to the second equation

2y + 4x = 4

2(-2x+2) + 4x = 4

distribute

-4x+4+4x=4

simplify

4=4

To figure out how many solutions it has:

•If both side of the equal sign are exactly the same: Infinitely many

ex: 6x=6x

•If both sides of the equal sign do not match when completely simplified: No solutions

ex: 3x=-5x

•If it creates an equation: 1 solution

ex: x=3+2y

Since both sides of the equal sign are 4, we have infinitely many solutions.

Answer:

A, B, and D

Step-by-step explanation:

Substitute all the coordinates into the equation. (x, y)

3(-2) - (-7) = 1

-6 - (-7) = 1

1 = 1

3(-1) - (-4) =1

-3 - (-4) = 1

1 = 1

3(0) - (1) = 1

0 - (1) = 1

-1 does not equal 1

3(3) - (8) = 1

9 - (8) = 1

1 = 1

The ordered pairs which are solutions to the equation 3x − y = 1 are:

By testing;

For A. (−2, −7); we have;

Answer:

The measure of the acute angle is 18.4°

Step-by-step explanation:

The angle between a line of equation y = m x + b and the positive part of the x-axis is Ф = [tex]tan^{-1}[/tex](m), which means tan Ф = m, where m is the slope of the line

Let us use this rule to solve the question

∵ A line of equation y = [tex]\frac{1}{3}[/tex] x + 4 makes with a horizontal line an acute ∠

→ Compare the equation of the line by the form of the equation above

∴ m = [tex]\frac{1}{3}[/tex]

→ Assume that the acute angle is Ф

∴ The acute angle between the line and the horizontal line is Ф

→ By using the rule above

∵ tan Ф = m

∴ tan Ф = [tex]\frac{1}{3}[/tex]

→ Use [tex]tan^{-1}[/tex] to find Ф

∵ Ф =  [tex]tan^{-1}[/tex] ( [tex]\frac{1}{3}[/tex] )

∴ Ф = 18.43494882

→ Round it to the nearest tenth

∴ Ф = 18.4°

∴ The measure of the acute angle is 18.4°

Hey there!

This answer to your question is it is false.

This is because you could have a rectangle with a length of 6 and a width of 4, and the area would be the same as a rectangle with a length of 8 and a width of 3. They would both be 24.

=======================================================

Explanation:

The vertical side of the blue triangle is PR = 2

The corresponding vertical side of the green triangle is P'R' = 4

The scale factor is the ratio of those two corresponding sides. So we divide the two side lengths.

scale factor = (P'R')/(PR) = (4)/(2) = 2

---------------------

We could also say:

scale factor = (R'Q')/(RQ) = (6)/(3) = 2

Or you could find the lengths of PQ and P'Q' through the distance formula, or Pythagorean theorem, and apply the same idea as shown above.

Answer:

c=8

Step-by-step explanation:

The value of c that makes z = -5/4 an extraneous solution is c = 24/5.

A linear equation is defined as an equation in which the highest power of the variable is always one.

The equation is given as:

√{4z + 9} = cz + 8

An extraneous solution is a solution that is not a valid solution to the original equation, but it is obtained during the process of solving the equation. In this case, the extraneous solution is z = -5/4.

To determine the value of c that makes z = -5/4 an extraneous solution, we can substitute -5/4 for z in the original equation. This gives us the following:

√{4 × -5/4 + 9} = -5/4 × c + 8

√{-5 + 9} = -5/4 × c + 8

√4 = -5/4 × c + 8

2 = -5/4 × c + 8

5/4 × c =  8 - 2

5/4 × c = 6

c = 6 × 4/5

c = 24/5

Therefore, the value of c that makes z = -5/4 an extraneous solution is c = 24/5.

Step-by-step explanation:

For #2:

[tex]\frac{3}{4}[/tex] x [tex]15[/tex].

It's that because there are 3/4 cups of honey for one cake. To use for 15 cakes, you would have to multiply it by 15.

For #3:

[tex]\frac{7}{8}[/tex] ÷ [tex]\frac{3}{4}[/tex].

It's that because the baker has 7/8 cups of honey. It takes 3/4 cups of honey for one cake. So you have to divide it by 3/4 cups in order to find out how many cakes.
