Someone Please Solve X For Me

Answers

Answer 1

Answer:

x = 20

Step-by-step explanation:

added together, the angles make 180

3x + 80 + 2x = 180

subtract 80 from both sides of the equation

3x + 80 - 80 + 2x = 180 - 80

combine like terms

5x = 100

divide both sides by 5

5x/5 = 100/5

x = 20

Answer 2

Answer:

x = 20

Step-by-step explanation:

added together, the angles make 180

3x + 80 + 2x = 180

subtract 80 from both sides of the equation

3x + 80 - 80 + 2x = 180 - 80

combine like terms

5 x = 100

divide both sides by 5

5x/5 = 100/5

x = 20

Answer:

Y=2x+0

Step-by-step explanation:

First you have to find the slope of the graph or the rise over run, which in this case is 2

Then you have to find the y intercept, which is zeroSo the rule for thos graph is y=2x+0.

To double check our work take a random point on x axis. I chose the point 1,2

fill in the formula and you should get 2(1)+0=2 and therefore this Formula is correct

Step-by-step explanation:

Graph y-2x=0

y−2x=0

Add 2x to both sides of the equation.

y=2x

Use the slope-intercept form to find the slope and y-intercept.

Slope: 2y-intercept: 0

Mya and ERIC WORK IN A BAKERY . MYA HAS 3 TIMEA AS MUCH FLOUR AS ERIC .MYA HAS 15.81LB OF FLOUR .USE THE EQUATION 3F = 15.81 TO FIND HOW MUCH FLOUR ERIC HAS .

Answers

Answer:

5.27 lb

Step-by-step explanation:

Given that,

Mya has 3 times as much floor as Eric. Mya has 15.81 lb of floor. The relation is given by :

Let Eric has F floor.

3F = 15.81 ...(1)

We need to find how much flour Eric has.

Dividing both sides by 15.81.

F = 15.81/3

F = 5.27 lb

Hence, Eric has 5.27 lb of flour.

A bike costs $350. It is on sale for 35% off.

What is the sale price of the bike?

Answers

Answer:

$227.50

Step-by-step explanation:

35% of $350 = 0.35 x 350 = $122.5

This is the amount that is reduced (subtracted) from the original price of $350.

 

The sale price is: $350 - $122.5 = $227.50

the answer is $122.5

Which function is linear?

Answers

Answer:

Its D

Step-by-step explanation:

The word linear is used for a straight line. A linear function is a function of a straight line, which means that the degree of a linear function must be 00 or 11. In this case, The degree of f(x)=x5−10f(x)=x5-10 is 11, which makes the function a linear function.

f(x)=x5−10f(x)=x5-10 is a linear function

Answers

Answer:

19

Step-by-step explanation:

Given the polynomial :

x2 + bx + 18 ;

The polynomial Given is if degree 2 ;

The equation can be solved using the quadratic function degree 2 to check which of the options given can be factored :

Here,

a = 1 ; b =? c = 18

Checking each option :

If b = 17

x2 + 17x + 18 = 0

x2 + 17x + x + 18 = 0

The equation of a straight line is y = 20 – X.
If the x value of a point on the line is 14, what is the y value of this point?

Answers

Given:

The equation of a straight line is

[tex]y=20-x[/tex]

The x value of a point on the line is 14.

To find:

The y value of this point.

Solution:

If a point (x,y) lines on line, then the equation of line must be stratified by that point.

We have, the equation of a straight line.

[tex]y=20-x[/tex]

Putting x=14, we get

[tex]y=20-14[/tex]

[tex]y=6[/tex]

Therefore, the y-value is 6 when the x-value is 14.

What property of operations will be used to simplify the product of a binomial and trinomial? *

Answers

Answer:

Distributive property.

Step-by-step explanation:

A distributive property is a rule that states that, multiplying two factors such as a binomial and trinomial would give the same result as multiplying the sum of two addends by the other factor.

Hence, the distributive property is used to simplify the product of a binomial and trinomial.

For example, let's find the product of (2x + 4)(5x² + 3x + 10)

First of all, we would distribute trinomial into each of the term in the binomial.

2x(5x² + 3x + 10) + 4(5x² + 3x + 10)

Distributing the monomial into the trinomial, we have;

2x(5x²) + 2x(3x) + 2(10) + 4(5x²) + 4x(3x) + 4(10)

Expanding the bracket, we have;

10x³ + 6x² + 10 + 20x² + 12x² + 40

Collecting like terms, we have;

10x³ + (6x² + 20x² + 12x²) + 10 + 40

10x³ + 38x² + 50

Therefore, (2x + 4)(5x² + 3x + 10) = 10x³ + 38x² + 50
