Answer 2

Answer:

x=20

Step-by-step explanation:

All triangles has the sum of the internal angle equal to 180

2x+10+3x+x+50=180

Combine like terms

6x+60=180

Subtract 60 on both sides

6x=120

Divide 6 on both sides

x=20

Hope it helped :))

What is the initial value of the function represented by this graph?

Answers

Answer:

We conclude that the initial value of the function is 6.

Hence, option D is correct.

Step-by-step explanation:

The initial value of the function can be determined by setting x = 0 and determining the corresponding y value.

In other words, the initial value is basically the y-intercept of the graph.

It is the output value when the input value x = 0.

Given the graph, it is clear that:

at x = 0, y = 6

Thus, at x = 0, the value of y is 6.

i.e. the y-intercept b = 6.

Therefore, we conclude that the initial value of the function is 6.

Hence, option D is correct.

Answer:

6

Step-by-step explanation:

The initial value is the y-intercept or where the line crosses the y axis.

What is the value of x in the equation 25x2 = 16. A. 5/4. B. 4. C. 4/5. D. 16/25

Answers

Answer:

x = ⅘

Step-by-step explanation:

For clarity, exponents should be marked with a ^.  25x² can be written as 25x^2.

25x² = 16

divide both sides by the 25

x² = 16/25

take the square root of both sides

x = √(16/25) = √16/√25 = 4/5

Clint completly filled his 18 gallon tank of gas with regular fuel for 55.08. As he left the gas station he noticed the station arcross the street sold regular fuel for 2. 99 Per gallon how much money could have clint saved per gallon is he had gone to the station across the street

Answers

Answer: 1.26

Step-by-step explanation:

Since he bought a 18 gallon tank of gas with regular fuel for 55.08.

The station across the street sold regular fuel for 2.99 per gallon. A 18 gallon tank will cost:

= 18 × 2.99

= 53.82

The amount that could have been saved would be:

= 55.08 - 53.82

= 1.26

Factor f(x) 3x^3-4x^2-28x-16 given that (x+2) is a factor

Answers

Step-by-step explanation:

3x³ - 4x² - 28x - 16

= (x + 2)(Ax² + Bx + C)

= Ax³ + (2A + B)x² + (2B + C)x + 2C.

By Comparing Coefficients, we have:

A = 3,2A + B = -4,2B + C = -28,2C = -16.

Solving them will give A = 3, B = -10 and C = -8.

Hence 3x³ - 4x² - 28x - 16

= (x + 2)(3x² - 10x - 8)

= (x + 2)(3x + 2)(x - 4).

The answer is f(x) = (x + 2)(3x + 2)(x - 4).

Point M is on line segment LN. Given MN = 3x, LN = 4x + 9, and
LM 2x + 7, determine the numerical length of LM.

Answers

Answer:

LM = 11 units

Step-by-step explanation:

Given M  is on LN , then

LM + MN = LN , substitute values

2x + 7 + 3x = 4x + 9

5x + 7 = 4x + 9 ( subtract 4x from both sides )

x + 7 = 9 ( subtract 7 from both sides )

x = 2

Thus

LM = 2x + 7 = 2(2) + 7 = 4 + 7 = 11

Simplify: -x - 4x + 2
