1. 90°
2. 25°
1. A straight line has an angle of 180°, and if one part of it measures 90°, then that means the other part has to measure 90°.
2. Again, a straight line measures 180°, and if one part measures 155°, the other part must measure 25° in order for the entire angle to measure 180°.
Hope this helps, and please consider marking branliest.
Y intercept is when x = 0
Look on the graph
Y intercept: (0, -1)
Slope: you can use rise/run by drawing a triangle. Rise = 4, rise = 2
4/2 = 2
The slope is 2
Equation formula : y = mx = b
m = slope, b = y intercept
Given the rest of the information already, plug the values in
Equation: y = 2x - 1
Answer:
60 is the value because it would not be 0
Step-by-step explanation:
Answer:
1.1 : C - x^2 + x - 2
1.2 : A - 4a^2 - 6b^2 + 12
Step-by-step explanation:
When we have the expression p(x) - q(x), we can substitute those functions in:
(x^2 + 2x - 5) - (x - 3)
We can distribute:
x^2 + 2x - 5 - x + 3
and then combine like terms(2x & -x, -5 & 3)
x^2 + x - 2
This is the same as C.
We can start by distributing:
a^2 - 2b^2 + 3 - 4b^2 + 5 + 3a^2 + 4
Now, we can combine all the a^2 terms(a^2 & 3a^2):
4a^2 - 2b^2 + 3 - 4b^2 + 5 + 4
Then, we can combine the b^2 terms(-2b^2 & -4b^2):
4a^2 - 6b^2 + 3 + 4 + 5
and lastly, all the constants:
4a^2 - 6b^2 + 12
This aligns with option A
