F(x) = 2x + 3 i think would be the best way to write it
(I'm not totally sure but there may be someone else with a more accurate/correct answer.)
Here is what I got (Red represents my work, blue represents to follow which steps and highlighter represents what the answer is):
Answer:
The slope of line h is -9/7
Step-by-step explanation:
mathematically, for two lines that are perpendicular to each other, the product of their slopes is equal to -1
say we have two lines l1 and l2, the product of their slopes m1 and m2 is -1
Mathematically;
m1 * m2 = -1
now, m1 here is 7/9 , we now proceed to calculate m2
7/9 * m2 = -1
7m2/9 = -1
7m2 = -9
m2 = -9/7
Answer:
(4,10) is the solution
Step-by-step explanation:
2x + y = 18
x – y = –6
Using elimination
2x + y = 18
x – y = –6
----------------------
3x = 12
Dividing each side by 3
3x/3 = 12/3
x =4
Now we can find y
2x+y = 18
2(4) +y =18
8+y = 18
Subtracting 8 from each side
8-8+y = 18-8
y=10
(4,10) is the solution
Answer:
C. <3, E. <1
Step-by-step explanation:
A triangle has 3 vertices, so it has exactly 3 interior angles, one at each vertex.
A triangle has 2 exterior angles at each vertex, so a triangle has 6 exterior angles. Each exterior angle is adjacent to an interior angle. The interior angles that are not adjacent to an exterior angle are that exterior angle's remote interior angles.
<6 is an exterior angle of the triangle. <5 is the other exterior angle at that vertex. <2 is an interior angle of the triangle and is adjacent to <6, so <2 is not a remote interior angle to <6.
The other two interior angles of the triangle are <1 and <3.
<1 and <3 are interior angles that are not adjacent to <6, so they are the remote interior angles to <6.
Answer: <1, <3
