Answer:
5
Step-by-step explanation:
slope = 
The second y point is 16 and the first is -4, so:
(16) - (-4)
Which can be written as 16 + 4 because a double negative makes a positive. Do the same for the x points, -7 and -3:
(-7) - (-3)
(-7) + (3)
Now solve both of them:
16 + 4 = 20
(-7) + 3 = -4
Remember, the slope formula is y over x, so we still need to put it into the fraction form:
You can reduce this to 
, or 5.
Answer:
x> 49 answer : D
Step-by-step explanation:
hello :
√x > 7
(√x)² >( 7)²
x> 49 answer : D
Answer:
d. 42 degrees
Step-by-step explanation:
y and 92 are supplemetary angles, which means they both add up to 180 since they are on the straight line.
Hence,
y+92 = 180
y = 180-92
y=88
And now we also know that all the angles of a traingle add up to 180,
so, we can simply find the x by:
88+x+50 =180
138 + x =180
x = 180-138
x = 42

Step-by-step explanation:
−3x2+2x−4+4x2+5x+9
=−3x2+2x+−4+4x2+5x+9
Combine Like Terms:
=−3x2+2x+−4+4x2+5x+9
=(−3x2+4x2)+(2x+5x)+(−4+9)
=x2+7x+5
Answer:
