The sum of the angle measures of any triangle is 180 degrees. Suppose that one angle in a triangle has a degree measure of 4x+10

and another has a degree measure of 3x+5 . Write an expression for the degree measure of the third angle in the triangle. Thanks

4x+10 + 3x+5 +y =180

solve for y  y=third angle

combine like terms

7x+15+y =180

subtract 7x+15 from each side

y = 180 -(7x+15)

y = 180 -7x-15

y = 165 -7x

The third angle equals 165-7x

Explain why functions with the property f(–x) = –f(x) are called odd functions and functions with the property f(–x) = f(x) are
anastassius [24]

Answer:

The functions with the property f(–x) =f(x) are called even functions because they symmetric about the y-axis and The functions with the property f(–x) = -f(x) are called odd because these function are symmetric about the origin .

Step-by-step explanation:

The functions with the property f(–x) =f(x) are called even functions because they symmetric about the y-axis . In other words these functions usually take a form x^2 ,x^4 ,x^6 ,x^8 etc . However ,there are other functions that behave like that too, such as cos(x).An even exponent does not always make an even function, for example (x+1)^2 is not an even function .

The functions with the property f(–x) = -f(x) are called odd because these function are symmetric about the origin . In other words they are called odd because of the functions like x, x^3 ,x^5 ,x^7, etc .but there are other functions that behave like that, too, such sin(x) .but an odd exponent does not always make an odd function, for example x3+1 is not an odd function.

Robin’s scores: 99, 108, 102, 107, 119 Mean = 107; MAD = 5. 2 Evelyn’s scores: 125, 137, 138, 145, 145 Mean = 138; MAD = 5. 6 Ex
IgorLugansk [536]

The absolute distance of the Evelyn scores from her mean score is greater than the absolute distance of Robin scores from his mean score.

<h3>What is Mean?</h3>

Mean is simply defined as the average of the given set of numbers. The mean is considered as one of the measures of central tendencies in statistics. The mean is said to be an arithmetic mean. It is the ratio of the sum of the observation to the total number of observations.

<h3>What is the mean absolute deviation?</h3>

Mean refers to the average of the observation and deviation means the variation from the present standard.

Given

Robin’s scores: 99, 108, 102, 107, 119

Mean = 107

MAD = 5.2

Evelyn’s scores: 125, 137, 138, 145, 145

Mean = 138

MAD = 5.6

The absolute distance of the Evelyn scores from her mean score is greater than the absolute distance of Robin scores from his mean score.

More about the mean and the mean absolute deviation link is given below.

Level 3<br> Solve: |x + 2|– 5 = -1
leonid [27]

Answer:

x=−6

x=2

Step-by-step explanation:

Combine like terms and use the properties of equality to get the variable on one side of the equal sign and the numbers on the other side. Remember to follow the order of operations.

∣x+2∣−5=−1

Add 5 to both sides of the equation.

∣x+2∣=4

Use the definition of absolute value.

x+2=4

x+2=−4

Subtract 2 from both sides of the equation.

x=2

x=−6
