Answer:

_3x>+31 but I am not sure

Step-by-step explanation:

-5x<-2x+8+23

-3x>+31

Answer:

x > -5

Step-by-step explanation:

1.) Add +5x on both sides

-5x + 8 < - 2x + 23

+5x         +5x      

8    <    3x + 23

2.) Subtract 23 from both sides

8    <    3x + 23

-23            -23

-15  <  3x

3.) Divide by 3 on both sides

-15 <  3x

 3        3

-5 < x

Because you divided by a negative, the sign flips

-5 > x

Answer:

x - 5y = - 10

Step-by-step explanation:

y = mx + b (b is y-intercept)

m = [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]

~~~~~~~~~~~~

x + 4y = 8 ⇔ y = [tex]-\frac{1}{4}[/tex] x + 2 ⇒ y-intercept is 2 and coordinates of y-intercept are (0, 2)

(5, 3)

m = [tex]\frac{3-2}{5-0}[/tex] = [tex]\frac{1}{5}[/tex]

y = [tex]\frac{1}{5}[/tex] x + 2 (slope-intercept form)

x - 5y = - 10 (standard form)

An open circle at 2, and an arrow facing left.

Answer:

Since, we are asked to present an exact solution, we are not able to give approximations.

The term exact means that you need to give the answer like this:

If we were asked to give an approximate result it would be like this x = 5,738.

Answer:

No, there is no enough flour for each of his friends to get a cupcake

Step-by-step explanation:

Let us use the ratio method to solve the question

∵ This recipe makes 2[tex]\frac{1}{2}[/tex] dozen cupcakes

∵ Each dozen contain 12 cupcakes

∴ The number of cupcakes can the recipe make = 2[tex]\frac{1}{2}[/tex]  × 12

∴ The number of cupcakes can the recipe make = 30 cupcakes

∵ The recipe calls for 3[tex]\frac{1}{3}[/tex] cups of flour

→ That means 3[tex]\frac{1}{3}[/tex] cups of flour can make 30 cupcakes

∴ 3[tex]\frac{1}{3}[/tex] cups of flour makes 30 cupcakes

∵ Anthony’s mother has only 1 cup of flour

→ By using the ratio method

→  flour  :  cupcake

→  3[tex]\frac{1}{3}[/tex]      :  30

→   1       :   x

→ By using cross multiplication

∵ 3[tex]\frac{1}{3}[/tex] × x = 1 × 30

∴ 3[tex]\frac{1}{3}[/tex] x = 30

→ Divide both sides by 3[tex]\frac{1}{3}[/tex]

∴ x = 9

∵ x represents the number of cupcakes  

∴ Anthony’s mother can make 9 cupcakes with 1 cup of flour

∵ Anthony has 12 friends at his daycare

∵ The number of the cupcakes = 9

∴ The number of cupcakes is not enough for each of his friends to

   get a cupcake

Answer:

x is negative

Step-by-step explanation:

I know x will be negative without solving the equation because we can see that both sides equal positive 8 and for -2x to be positive the x value must be negative. when two negative values are multiplied they change into positive. If the x value was Positive this equation would be false.

Hope this helps you

Answer:

Yes, x will be negative.

We are given:

-2x + 4 = 8

This means that "something", in this case -2x, added to 4, equals 8

The only thing that can add to 4 and equal 8 is 4.

So, that means -2x has to equal 4, which is a positive number.

Negative x negative = positive.

-2 is already a negative number, so x has to be a negative number.

Answer:

2(x-3x) + 3

value of X and M is x and -3x respectively

Step-by-step explanation:

you can factor out the 2 from the 2x -6x and gets the 2(x-3x) while n is the constant that remains the value of 3

I hope this helps

Answer:

m = - 3, n = - 6

Step-by-step explanation:

Expand and compare coefficients of like terms, that is

(x + m)² + n

= x² + 2mx + m² + n

Compare to x² - 6x + 3

comparing coefficients of x- term

2m = - 6 ( divide both sides by 2 )

m = - 3

Comparing constant terms

m² + n = 3 , that is

(- 3)² + n = 3

9 + n = 3 ( subtract 9 from both sides )

n = - 6

Answer:

Step-by-step explanation:

1. Make a proportion.

Set the numbers equal to each other.

I chose the numbers 9, 12, 15, and of course x.

Make the fractions in a way that the x is in the numerator if you want to make your life easier.

15/9 = x/12

2. Simplify

Cross multiply the numbers.

This will give you the equation of

9*x and 15*12

3. Make an equation

Simplify the numbers by mulitplying them

9x = 180

4. Divide both sides by 9

9x = 180

/9      /9

Answer:

Δ ABC and Δ DEF are similar because their corresponding sides are proportional

Step-by-step explanation:

Two triangles are similar if their corresponding sides are proportional which means the corresponding sides have equal ratios

In the two triangles ABC and DEF

∵ AB = 4 units

∵ DE = 2 units

∴ [tex]\frac{AB}{DE}=\frac{4}{2}=2[/tex]

∵ BC = 6 units

∵ EF = 3 units

∴ [tex]\frac{BC}{EF}=\frac{6}{3}=2[/tex]

∵ CA = 2 units

∵ FD = 1 units

∴ [tex]\frac{CA}{FD}=\frac{2}{1}=2[/tex]

∴ [tex]\frac{AB}{DE}=\frac{BC}{EF}=\frac{CA}{FD}=2[/tex]

∵ All the ratios of the corresponding sides are equal

∴ The corresponding sides of the two triangles are proportional

∴ Δ ABC is similar to Δ DEF
