I think it is C)
I’m really sorry if I’m wrong.
Answer:
8 books
Step-by-step explanation:
5+3=8
Answer:
38°
Step-by-step explanation:
Complementary means that they add up to 90
So then to find the measure of angle 2, subtract the measure of angle 1 from 90.
90-52=<u>38</u>
Answer:
x = 1 or x = ± i
Step-by-step explanation:
Note the sum of the coefficients
1 - 1 + 1 - 1 = 0
This indicates that x = 1 is a root, thus (x - 1) is a factor
Using long division or synthetic division, then
x³ - x² + x - 1 = (x - 1)(x² + 1), thus
(x - 1)(x² + 1) = 0
Equate each factor to zero and solve for x
x - 1 = 0 ⇒ x = 1
x² + 1 = 0 ⇒ x² = - 1 ⇒ x = ±
= ± i
Answer:
Yes
Step-by-step explanation:
To find the y intercept of this formula, you first need to convert it into slope intercept form.
x+y=1
y=-x+1
Here, the slope is negative 1 and the y intercept is (0,1). If you imagine the line with a slope of negative 1, it will indeed cross the x axis at (1,0). Hope this helps!
