Answer:
-6
Step-by-step explanation:
-1+(-5)
You are moving down the numberline, then subtracting again because of the negative sign. -(1+5) is how I like to think of it.
So, 1+5=6, and you add the negative sign. -1+(-5)=-6.
Answer:
you would use 85 to find angle 4, because they would add up to 180, so you would subract 85 from 180 to get angle 4
Step-by-step explanation:
Fist, in the equation y=mx+b, b is the y-intercept. The y-intercept is the poin on the line that crosses the x-axis; the y-intercept is the value of yThese equations follow that format.
Y=mx+b
y

3x-4. <-----In this equation, the slope(m)=3 b= -4.
On the graph, we can see that the line crosses the x-axis at y=-4. Knowing that, we can eliminate the answer choices with +4 in the inequality.
The next step, is to pick an (x,y) coordinate that is in the shaded region and plug it into the remaining 2 inequalities. Which ever inequality is true after you solve it, that is the correct answer.
For example, I'll choose to plug in (-4,4) into the y

3x-4.
y

3x-4.
(4)

(3(-4))-4.
(4)

(-12)-4.
(4)

-16
So, this statement is true becasue -16 is less than positive 4. Therefore, the correct answer would be
y
3x-4. Hope that helped! Comment back with any further questions!

Answer:
BC= 20 units
Step-by-step explanation:
Since ∆ ABC is an equilateral triangle, all the sides are equal in length.
AC= BC
=>-y+23= 6y+2
=>-y-6y= 2-23
=>-7y= -21
=>y= 21/7
=>y= 3
BC = 6y+2 = 6(3)+2 = 18+2 = 20 units
