Answer:
x = 17 degrees y = 3 units
Step-by-step explanation:
Since angle F and E are equal, sides DE and DF are equal and you now have an equilateral triangle
each angle is 60 degrees so 4x - 8 = 60 shows x = 17
since the sides are equal : 8y-3 = 6y+3 shows y = 3
Answer:
x = 17 , y = 4
Step-by-step explanation:
since EF and DF are congruent , then
8y - 5 = 6y + 3 ( subtract 6y from both sides )
2y - 5 = 3 ( add 5 to both sides )
2y = 8 ( divide both sides by 2 )
y = 4
--------
the triangle has 3 congruent angles , then
3(4x - 8) = 180 ( divide both sides by 3 )
4x - 8 = 60 ( add 8 to both sides )
4x = 68 ( divide both sides by 4 )
x = 17

Which inequality pairs with y≤−2x−1 to complete the system of linear inequalities represented by the graph?
y<−2x+2
y>−2x+2
y<2x−2
y>2x−2
Answers
Answer:
To graph the inequality
y < 2x - 5
we graph the dashed boundary line y=2x-5 with a positive slope of 2 and y-intercept (0,-5) and shade everything to the right.
To graph the inequality y>-3x+1, we graph the dashed boundary line y=-3x +1 with y-intercept (0,1) and shade every above it.
The intersection of the two shadings is the solution to the system of inequalities:
y < 2x - 5

Maria can stack a pile of wood in 20 minutes, and
alex can stack the same pile of wood in 12 minutes.
how long will it take them both working together
to stack the same pile of wood?
Answers
Answer:
7.5 minutes
Step-by-step explanation:
The stacking rate working together is assumed to be the sum of the separate stacking rates. The rates are given in terms of minutes per pile, but we need to do the computation with rates in terms of piles per minute.
__
total rate = Maria's rate + Alex's rate
= 1/20 piles/min + 1/12 piles/min = (12 +20)/(20·12) piles/min
= 32/240 piles/min = 2/15 piles/min
Then the rate in terms of minutes per pile is ...
1/(2/15 piles/min) = 15/2 min/pile = 7.5 min/pile
When both work together, it will take them 7.5 minutes to stack a pile of wood.

The solution set of the equation is (0, 7)(-1, 6)
y = x² + 2x + 7
y = x + 7
How to find the solution of an equation sets?
y = x² + 2x + 7
y = x + 7
x² + 2x + 7 = x + 7
x² + 2x - x + 7 - 7 = 0
x² + x = 0
x(x + 1) = 0

y = x + 7
y = 0 + 7
y = 7
when x = -1
y = -1 +7
y = 6

Answers
Answer:
m = 1
c = 4
Step-by-step explanation:
First let's review what a slope-intercept form is.
Slope-intercept form is a specific form of linear equations. It always has y on one side and all the other terms on the other. Its structure is:
[tex]y = mx + c[/tex],
where m is the slope and c is the y-intercept.
You can easily read slope (m) and intercept (c) in your equation.
[tex]y = mx + c\\y = x + 4[/tex]
You can see that m in front of x is 1, because x = 1x. Multiplying with 1 perserves the number.
So:
[tex]m = 1\\c = 4[/tex]
