Answer:

  x = 20

  y = 70

Step-by-step explanation:

The exterior angle marked 40° is the sum of the remote interior angles in the isosceles triangle at lower right, both of which are x°.

  40° = 2x°

  x = 20 . . . . . divide by 2°

The angle marked y° is the complement of the one marked x°.

  y = 90 -x = 90 -20

  y = 70

Answer:

y = -4/3x - 1

Answer: the answer is yes

Step-by-step explanation:

the inequality is underlined so the circle is going to be opened and since x is greater than -1 the line is drawn towards the left.

Answer:

yes

Step-by-step explanation:

Answer:

m>z=85

x = 15!

Step-by-step explanation:

85=z because they are opposite eachother and the two lines intersect.

85*2=170, so we have 170 degrees for the two angles we know the measure of. Now, we need to find the remaining angles.

360-17=190. There is 190 degrees that need to be solved still.

190/2 is 95. Each angle remaining is 95 degrees.

8x-25=95

+25

8x = 120

/8

x=15

The equivalent of the given expression (6x−4)(3x−1) is 18x² - 18x + 4.

Hence, option C)18x² - 18x + 4 is the correct answer.

FOIL Method is simply a method used to multiply binomials where one multiply first terms and then the outside terms, next,  inside terms and then last terms, and finally, combine like terms.

Given the expression in the question;

(6x−4)(3x−1)

Expand using FOIL method, apply the distributive property.

(6x−4)(3x−1)

6x( 3x − 1 ) - 4( 3x − 1 )

(6x × 3x ) + ( 6x × -1 ) - ( 4 × 3x ) - ( 4 × -1 )

Simplify

(6x × 3x ) + ( 6x × -1 ) - ( 4 × 3x ) - ( 4 × -1 )

18x² + (-6x) - (12x) - (-4)

Remove parenthesis and combine like terms

18x² - 6x - 12x + 4

18x² - 18x + 4

The equivalent of the given expression (6x−4)(3x−1) is 18x² - 18x + 4.

Hence, option C)18x² - 18x + 4 is the correct answer.

Answer:

1) use a calculator

2) use desmos which is an online graphing calculator (trust me it will help you)

3) Do lots of practice (I know that you probably don't like to practice, but if you practice then you will prevent lots of careless errors because you will have more experience)

4) Pay attention to your teacher

5) When taking a test, try to avoid all distractions and focus on your test.

Answer:

For me, it really helps to go back and see what i got wrong, check where i made the mistake and solve it again. I think you need to know the basic concept before moving on since math builds on itself. If you have a teacher i think it would really help if you talk to them too, they may have some good tips to help you :)

Answer:

18x+27y

Step-by-step explanation:

When dividing powers that have the same base, subtract the exponents.

So 4³/4⁵ is the same as 4³ ⁻ ⁵ or 4⁻².

When we have a base taken to a negative exponent,

it means the same thing as 1 over the base to the positive exponent.

In other words, we can rewrite 4⁻² as 1/4² or 1/16.

Answer:

3.080 calzados.

Step-by-step explanation:

Dado que Umaloja vendió 2.800 calzados el mes pasado, y este mes vendió un 10% más, para determinar cuantos calzados fueron vendidos este mes se debe realizar el siguiente cálculo:

2800 + ((2.800 x 10) / 100) = X

2.800 + (28.000 / 100) = X

2.800 + 280 = X

3.080 = X

Así, este mes Umaloja vendió 3.080 calzados.

Answer:

The limit is 1.

Step-by-step explanation:

In this kind of problem, we can use the left and right-hand limit method.

Basically, we need to find the limit by the left side and then by the right side. If both of them are equal the limit does exist if not the limit does not exist.

Left hand

[tex]lim_{-8^{-}}(f(x))=lim_{-8^{-}}(x+9)=-8+9=1[/tex]        

Right hand

[tex]lim_{-8^{+}}(f(x))=lim_{-8^{+}}(-7-x)=-7-(-8)=1[/tex]  

As we see, both limits are the same, so the limit is equal to 1.
