The answer:
solve for x does mean, finding the value of x
as we see in the figure, the first step to find such a value is equalizing <span>3x-8 to
</span><span>2x+23, that is possible because the right angle was bisected by a line, so the value of each angle must be equal.
to find x, </span>3x-8 = 2x+23 , equivalent to 3x - 2x =23 +8 = 31
x =31°
finally
the steps are true, 1, 2 and 3

Answer:
-70
Step-by-step explanation:
As shown in the picture, you can use the formula:
1st term + common difference(desired term -1)
From what is given, we can see that the first term is -2. We are looking for the 18th term, so 18 is our desired term. Lastly, to find the common difference, we can subtract a the term before a certain term from it:
common difference = -6 - (-2) = -4
Now, we can substitute what we have:
-2 + (-4)(18 - 1)
-2 - 4(17)
-2 - 68
-70
Answer:
y = - 2(x + 4)² + 6
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Here (h, k ) = (- 4, 6 ) , thus
y = a(x - (- 4) )² + 6 , that is
y = a(x + 4)² + 6
To find a substitute (- 2, - 2) into the equation
- 2 = a(- 2 + 4)² + 6 ( subtract 6 from both sides )
- 8 = a(2)² = 4a ( divide both sides by 4 )
- 2 = a , thus
y = - 2(x + 4)² + 6 ← equation in vertex form
A negative number divided by positive is a negative quotient and vice versa.
So
5.7 / -2.2
-0.01 / 0.05
Are the ones with negative quotients
