Step-by-step explanation:
sum of 2 angles on a straight line = 180°
therefore,
y + 120 = 180
y = 180 - 120 = 60
y = 60°
now apply angle sum property of triangle
now,
50 + x + y = 180
50 + x + 60 = 180
110 + x = 180
x = 180 - 110
x = 70
therefore, x = 70 & y = 60
hope this answer helps you dear! take care
Answer:
x = 70°
y = 60°

Write an equation of the line in slope intercept form (-2,4) (0,0)
Answers
Answer:
y = -2x
Step-by-step explanation:
Slope = (change in y-values)/(change in x-values)
Slope = (0 - 4)/(0 - (-2)
Slope = -4/2
Slope = -2
Use the slope = -2 and point (0, 0) and substitute into y= mx + b to solve for b
y = mx + b
0 = -2(0) +b
0 = b
The equation of the line y = -2x + 0 or y = - 2x
if y varies directly as x, and y is 20 when x is 4, what is the value of y when x is 80
Answers
Answer:The equation of that is y=kx
Substitute it in and you get
20=6k
Divide 6 on both sides
k=3 1/3
Then since it asks what is the value of y when x is 24 use k in the equation
y=3 1/3*24
so y=80 is the answer

or,x/3<4+2
or,x<6/3
or,x<2
Answer:
x < 18
Step-by-step explanation:
You solve it like an equation.
First, isolate the x-value to one side by adding 2 to each side:
x/3 - 2 + 2 < 4 + 2
The twos on the left side cancel out:
x/3 < 6
Now multiply both sides by 3:
x/3 x 3 < 6 x 3
The threes on the left side cancel out, leaving you with the x-value:
x < 18
Hope this makes sense :)

Find the slope of the line that passes through point A (-2,0)and point B (0,10) using m=rise/run
Answers
Answer:
m = 5
Step-by-step explanation:
The x-coordinate of A is -2 and that of B is 0. The increase in this coordinate from A to B is 2. Similarly, the y-coordinate increases by 10. The slope is therefore m = rise / run = 10/2, or m = 5

Cookies cost $5.40 per dozen. What is the unit rate Price per cookie
Answers
Answer:
$0.45 per cookie
Step-by-step explanation:
1 dozen = 12, so you divide both sides by 12. 5.40/12 would equal $0.45 per cookie
Answer:$0.45
Step-by-step explanation:
If it costs $5.40 for 12 cookies then you will need to find how much it costs for 1 cookie. To do this you will need to divide 5.4 by 12 so 5.4/12=0.45
Given that y varies with directly with x, and that y= 12 when x=3. Then when x=10, y= ?
Answers
Answer:
y = 40
Step-by-step explanation:
Given that y varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 12 when x = 3 , then
12 = 3k ( divide both sides by 3 )
4 = k
y = 4x ← equation of variation
When x = 10 , then
y = 4 × 10 = 40
