13 = r/9 + 8
subtract 8 from each side
5 = r/9
multiply 9 from each side
r = 45
Compound event is the answer
Answer:
<u>y = 10/11 x + 2.45</u>
Step-by-step explanation:
Equation of the line
First find the gradient
formula = 
= 
=
= 10/11
m is the gradient
equation of a line
y- y1 = m(x-x1)
y-7 = 10/11 (x-5)
y-7 = 
- 
<u>y = 10/11 x + 2.45</u>
<u />
<em>NB i rounded of -50/11 +7 = 2.4545..... to 2.45 </em>
Hey there! :)
Answer:
a. 3
b. -22
c. -2
d. -2
e. 5a + 8
f. a² + 6a + 3
Step-by-step explanation:
Calculate the answers by substituting the values inside of the parenthesis for 'x':
a. f(1) = 5(1) - 2 = 3
b. f(-4) = 5(-4) - 2 = -22
c. g(-3) = (-3)² + 2(-3) - 5 = 9 - 6 - 5 = -2
d. g(1) = 1² + 2(1) - 5 = 1 + 2 -5 = -2
e. f(a+ 2) = 5(a+2) - 2 = 5a + 10 - 2 = 5a + 8
f. g(a + 2) = (a + 2)² + 2(a + 2) - 5 = a² + 4a + 4 + 2a + 4 - 5 =
a² + 6a + 3
