the y-intercept would be -11 because slope-intercept formula is always like this; y = mx+b. b is y-intercept and m is slope. so therefore, it would be -11
Answer:
ask your teacher for help
Step-by-step explanation:
complementary angles = 90
2x-5 + 5x+4 = 90
combine like terms
7x-1 =90
7x = 91
divide by 7
x =13
angle a
2x-5
2*13-5
26-5
21
Angle a: 21
Answer:
No, the student is not correct. The correct expression is 9(n+13).
Step-by-step explanation:
"9 times the sum of a number and 13" means you must multiply 9 by the sum, not just by the number. 9n + 13 would be "the sum of 9 times a number and 13." Slightly different wording.
Interior angles are the angles on the interior of a shape, for example the interior angles of a square are 90(degrees)
