Type the equations to a website called maths papa-using their algebra calculator, i highly recommend it, it shows all the working clearly and the answers are always correct
4a-13=19 add 13 to both sides
4a=32 divide by 4 on both sides
a=8
Answer:
A=0.5(a+b)h
=0.5(27+17)4=88units^2
Step-by-step explanation:
Answer:
This is a binomial experiment
Step-by-step explanation:
Binomial experiment is an experiment in which for each trial there are only two outcomes.
In case of the given experiment, it is being asked either the applicants were admitted to the Park university or not, it has only two outcomes, Yes and no. So having only two options as outcomes this experiment is a binomial experiment ..
Answer:
y = - 
x - 
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Rearrange 5x + 9y + 18 = 0 into slope- intercept form
Subtract 5x + 18 from both sides
9y = - 5x - 18 ( divide all terms by 9 )
y = - x - 2 ← in slope- intercept form
with m = -
Parallel lines have equal slopes, thus
y = - x + c ← is the partial equation
To find c substitute (- 5, - 7) into the partial equation
- 7 = 
+ c ⇒ c = - 7 - = -
y = - x - ← equation of line
