Find The Value Of X On A Triangle

Answers

Answer 1

Answer:

x = 25

Step-by-step explanation:

The sum of the angles of a triangle is 180 degrees.

90 + x+ 2x+15 =180

Combine like terms

105+3x = 180

Subtract 105 from each side

105+3x-105 = 180-105

3x =75

Divide each side by 3

3x/3 = 75/3

x = 25

Answer 2

Answer:

25°

Step-by-step explanation:

2x + 15° + x + 90 °= 180° ( being sum of angles of triangle)3x + 105° = 180 °3x = 180 °- 105°3x = 75° x = 25°hope it helps :)

Step-by-step explanation:

2x+3y=5.........eq1

x-2y=-1........eq2

therefore: x=-1+2y

Subt. eq 3 into eq2

2x+3y=5

Answer:

(3x² - 6x + 11) - (10x² - 4x + 6) is equivalent to expression -7x² - 2x + 5

(-3x² - 5x - 3) - (-10x² - 7x + 2) is equivalent expression to 7x² + 2x - 5

(12x² + 6x - 5) - (5x² + 8x - 12) is equivalent expression to 7x² - 2x + 7

Step-by-step explanation:

✔️(3x² - 6x + 11) - (10x² - 4x + 6)

Open the bracket by applying the distributive property

3x² - 6x + 11 - 10x² + 4x - 6

Add like terms

-7x² - 2x + 5

Therefore:

(3x² - 6x + 11) - (10x² - 4x + 6) is equivalent to expression -7x² - 2x + 5

✔️(-3x² - 5x - 3) - (-10x² - 7x + 2)

Apply distributive property

-3x² - 5x - 3 + 10x² + 7x - 2

Add like terms

7x² + 2x - 5

Therefore:

(-3x² - 5x - 3) - (-10x² - 7x + 2) is equivalent expression to 7x² + 2x - 5

✔️(12x² + 6x - 5) - (5x² + 8x - 12)

12x² + 6x - 5 - 5x² - 8x + 12

Add like terms

7x² - 2x + 7

Therefore:

(12x² + 6x - 5) - (5x² + 8x - 12) is equivalent expression to 7x² - 2x + 7

The given function is a piecewise function with characteristics that vary with the value of x.

Please find attached the graph of h(x).

Reasons:

The given information is presented as follows;

From the above piecewise function, we have;

For x ≤ 0, the slope of the graph of h(x) =

For 0 < x ≤ 3, the slope of the graph of h(x) =

For x ≥ 4, the slope of the graph of h(x) =

Therefore, as we progress from left to right, the slope of h(x) increases and

the slope of the graph becomes steeper.

The graph of h(x) is plotted with the given equations using MS Excel as

shown in the attached diagram.

Solve the system using substitution.
X + 2y = -6
6x + 2y = 4
([?], [ ]

Answers

Answer:

Step-by-step explanation:

Rearrange x+2y=-6 to solve for x:

x = -2y-6

substitute -2y-6 for x into the second equation:

6x + 2y = 4

6(-2y-6) + 2y = 4

-12y-36 + 2y = 4

-10y  = 40

y  = -4

x = -2y-6 = 2

(x,y) = (2,-4)

The solution for the system of equations is (2,-4).

The given system of equations are x + 2y = -6-----(1) and 6x + 2y = 4-----(2).

How do solve systems of equations using the substitution method?

To solve a system of equations using substitution:

Step 1: Isolate one of the two variables in one of the equations.Step 2: Substitute the expression that is equal to the isolated variable from Step 1 into the other equation. This should result in a linear equation with only one variable.Step 3: Solve the linear equation for the remaining variable.Step 4: Use the solution of Step 3 to calculate the value of the other variable in the system by using one of the original equations.

Now, rearrange x+2y=-6 to solve for x:

So, x = -2y-6

Substitute -2y-6 for x into the second equation 6x + 2y = 4.

That is, 6(-2y-6) + 2y = 4

⇒-12y-36 + 2y = 4

⇒-10y = 40

⇒y = -4

By substituting y = -4 in x = -2y-6 we get x=2.

Therefore, the solution for the system of equations is (2,-4).

How do matter and energy move through an ecosystem?

Answers

Step-by-step explanation:

How Matter Moves Through Ecosystems

Decomposers release nutrients when they break down dead organisms. The nutrients are taken up by plants through their roots. The nutrients pass to primary consumers when they eat the plants. The nutrients pass to higher-level consumers when they eat lower-level consumers. When living things die, the cycle repeats.

How Energy Moves Through Ecosystems

Energy is transferred between organisms in food webs from producers to consumers. The energy is used by organisms to carry out complex tasks. The vast majority of energy that exists in food webs originates from the sun and is converted (transformed) into chemical energy by the process of photosynthesis in plants. A small proportion of this chemical energy is transformed directly into heat when compounds are broken down during resp​iration in plants. The majority of the chemical energy stored in plants is transformed into other forms by an assortment of consumers, such as cows, rabbits, horses, sheep, caterpillars, and other insects eating plants.
