Answer:

x=70 degrees, y= 30 degrees, z=20 degrees

Step-by-step explanation:

110+x=180 => straight angle def.

180-110+40=y => def. of angles in triangle

x( 70 degrees) +90+z=180, z= 20 => angles in triangle

Answer:

x=70

z=20

y=30

Step-by-step explanation:

first find x: the sum of straight angle is 180

x+110=180

x=180-110=70

now find z: the sum of the angles of triangle is 180:

x=70, right angle=90

z+70+90=180

find y:

y+110+40=180

y=180-150=30

z=180-160=20

Which equation represents a line which is parallel to the line y=1/5x -1
masha68 [24]

9514 1404 393

Answer:

  (c) 5y - x = -20

Step-by-step explanation:

When the x- and y-terms are on the same side of the equation, the slope of the line will be ...

  m = -(coefficient of x)/(coefficient of y)

So, the slopes of the offered choices are ...

  a) -5/1 = -5

  b) -1/5

 c) -(-1)/5 = 1/5 . . . . . parallel to given line

  d) -5/-1 = 5

The lines will be parallel when their slopes are the same. The slope of the given line is the coefficient of x, 1/5. Choice C has the same slope.

For 16 and 17, use the dot plot of the number
otez555 [7]

Answer:

The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.

The median is also the number that is halfway into the set. To find the median, the data should be arranged in order from least to greatest. If there is an even number of items in the data set, then the median is found by taking the mean (average) of the two middlemost numbers.

The range of a set of data is the difference between the highest and lowest values in the set. To find the range, first order the data from least to greatest. Then subtract the smallest value from the largest value in the set.

Answer:

Option C - 2(-5)+2(3) ; -4

Step-by-step explanation:

Distributive property means breaking up the factors and multiplying them separately

So here we have 2(-5+3) = 2(-5)+2(3) = (-10)+(6) = (-4)

So (-4) is the value.

Hope this helps you.

Write an equation (in slope-intercept form) of the line that passes through (0, 3) and (−5, 2.5).
Paladinen [302]

The equation of the line passing throught the points A(x_A,y_A) and B(x_B,y_B) has a form

\dfrac{x-x_A}{x_B-x_A}=\dfrac{y-y_A}{y_B-y_A}.

Now the equation of the line passing through points (0, 3) and (−5, 2.5) is

\dfrac{x-0}{-5-0}=\dfrac{y-3}{2.5-3}.

Simplify it:

\dfrac{x}{-5}=\dfrac{y-3}{-0.5},\\ \\0.5x=5(y-3),\\ \\5x=50y-150,\\ \\x=10y-30,\\ \\10y=x+30,\\ \\y=0.1x+3.

This equation is in slope-intercept form.

Answer: y=0.1x+3.
