Answer:
x = 66
Step-by-step explanation:
the sum of the 3 angles in a triangle = 180°
sum the 3 angles and equate to 180
x + 35 + 79 = 180 , that is
x + 114 = 180 ( subtract 114 from both sides )
x = 66

The local machine shop hired John Dalton as a press operator his annual salary is $34,268 if John is paid weekly what is the amount of his weekly salary
Answers
Answer:
$659 weekly
Step-by-step explanation:
John Dalton earns $34,268 annually (yearly)
We want to find his weekly rate if he is paid weekly.
To do so we divide his annual salary by the number of weeks in a year (52)
So weekly rate = 34,268 / 52 = 659

What is the sum of the fractions?
Answers
Answer:
-3/4
Step-by-step explanation:
Problem
-1 1/4 + 1/2
Comment
This combined with the number line is to help you visualize how fractions can be represented and how you find their sum.
The rule is move left when the number is minus. Move right when the number is plus.
so -1 1/4 = (4*-1 -1 )/4 = - 5/4
Start at 0 and move left. The number beside - 1 on the number line is -5/4 Put an arrowhead on the line you just drew. The arrowhead should be just about -5/4.
Each mark on the number line is 1/4 away from the next quarter on the number line.
1/2 = 2/4
So since 1/2 is plus, you move right. You need 2 marks right of -5/4. You will find that is at -3/4

in a group of 60 workers they get paid an average of 80$ a day per person.
if some earn $75 a day and the rest earn $100 a day, how many earn $75 a day
Answers
Answer:
48 workers earn $75 a day.
Step-by-step explanation:
Let x people earn 75 a day then 60-x earn 100 dollars a day.
Average is $80 a day so total paid out to the 60 workers
= 60*80 = $4800.
So 75x + 100(60-x) = 4800
75x + 6000 - 100x = 4800
6000 - 4800 = 100x - 75x
1200 = 25x
x = 48.

how: because there arnt like terms in the two equations you find which number you can military to the equations to make one of the numbers the same. in this case i multiplied the top equation by -2y from the bottom equation (5x-3y=16)^-2 then multiplied the bottom equation by 3y (4x-2y=14)^-3 both equations multiplied are (-10x+6y=-32) and (-12x+6y=-42) now that we have two of the same terms (6y) they are the same signs (both positive) so we switch the sign on the bottom equation. (12x-6y=42) and because there the same we subtract the equations. (-10x+6y=-32) - (12x-6y=42)= 2x=10. the y cancels out. and now we divide 2 by 2x and that leaves x then we divide 2 by 10 =5 so your x=5 to find y we take any ORIGINAL equation im using (4x-2y=14) we use our x and replace 4x to 4(5)=20x making our new equation (20x-2y=14) we subtract -20 to 20 . cancels out 20 and leaves us with 2y=14 then subtract 20 it to 14. which gives us -6 (-2y=-6)
divide -2y by -2 which gives us y alone. then divide -2 by 6 gives -3. (y=-3) making (5,-3) your answer.

Hey there!
Guide:
Negative & negative = positive
Positive & positive = positive
Negative & positive = negative
Positive & negative = negative
For -10 + 7 = -3 it doesn’t give you a POSITIVE because you’re working with a negative (-10) and a positive (7), which it results out to be a negative number (-3)
Whereas, -8 - 3 = -11, it doesn’t also give you a positive because you’re working with a negative (-8) and a somewhat positive (3 or -3 it depends how you look at the equation), it gave you a negative result (-11).

Answer:
[tex]f(x) = -\dfrac{7}{4}|x-5|+0 [/tex]
Step-by-step explanation:
The function in the coordinate Plane is an absolute value function . Consider the parent function
[tex]f(x) = |x| [/tex]
Recall the properties of transformation
f(x+a), If a<0 ⇒ It moves to righta.f(x),If a<0 ⇒ It flips upsidedownf(x)+a,If a>0 ⇒ It moves up & a<0 It moves downFrom the inspection of the graph,It has moved to right by 5 units, Thus
[tex]f(x - 5) = |x - 5| [/tex]
Apparently, It has neither shifted up or down, hence
[tex]f(x - 5) +0= |x - 5|+0 [/tex]
Looking at the graph, we can see that it has been reflected vertically. It tells us we have to multiply it by a negative constant
[tex] -a f(x - 5) +0= -a |x - 5| +0[/tex]
take (9,7) to figure out a.
set x to 9 and the LHS expression to 7[tex] -a | 9- 5| =7[/tex]
Solving the equation yields:
[tex] \boxed{a = - \frac{7}{4} }[/tex]
hence, our function is [tex]\boxed{f(x) = -\dfrac{7}{4}|x-5|+0} [/tex]

2x ≥ 30 - 4x
Add 4x to each side :
2x + 4x ≥ 30 - 4x + 4x
6x ≥ 30
Divide both sides by 6 :
1/6 x 6x ≥ 1/6 x 30

A - B is the complement of B in A; in other words, all the elements of A that do not belong to B.
Since A ∩ B = {4, 6}, we have
A - B = {2, 8, 10}
Then the complement of A - B, denoted (A - B)' is all the elements of the universal set U that do not belong to A - B.
(A - B)' = {1, 3, 4, 5, 6, 7, 9}

Answers
The function h(x) is a translation of the exponential function [tex]g(x) = 2(3)^{x - 4}[/tex] , is [tex]h(x) = 4(3)^{x + 7} - 9[/tex]
What are exponential functions?When the expression of function is such that it involves the input to be present as an exponent (power) of some constant, then such function is called exponential function.
There usual form is specified below. They are written in several such equivalent forms.
The function h(x) is a translation of the exponential function given as
[tex]g(x) = 2(3)^{x - 4}[/tex]
We have to determine, the h(x) if the translation is a vertical stretch by a factor of 2, a vertical shift upward of 9 units, and a horizontal shift to the right 7 units.
The function h(x) is vertically stretched by 2.
[tex]h(x) = 2 (2(3)^{x - 4})\\\\h(x) = 4((3)^{x - 4})[/tex]
Vertically shift upward by 9,
[tex]h(x) = 4((3)^{x - 4})\\\\h(x) = 4((3)^{x - 4})- 9[/tex]
And a horizontal shift to the right 7 units,
[tex]h(x) = 4((3)^{x - 7})- 9[/tex]
The function h(x) is a translation of the exponential function [tex]g(x) = 2(3)^{x - 4}[/tex] , is [tex]h(x) = 4(3)^{x + 7} - 9[/tex]

Which is a property of polygons?
A polygon has a maximum of 100 sides
A polygon is a solid figure
A polygon is a open figure
A polygon is a plane figure
Answers
Answer:
A polygon is a plane figure.
Step-by-step explanation:
This means it is a 2 dimensional shape that lies flat, it has length and width, it has area but no thickness.
There is no max number of sides, so the first answer is not right.
In math, saying it is solid means its 3-d, so that is not right (it's only 2-d)
Saying its open, means that somewhere on the shape, the sides don't meet up at a corner, like an animal corral with the gate left open. So that's not right. Part of the definition of a polygon is that it is closed.
It is a 2-d shape with straight sides and closed, it lies flat in a plane. The last answer is correct.
Answer:
A polygon is a plane figure.
