Answer:
solution: x = -8
Step by step:
1) 5x-5+5 = -45+5 : Add 5 to both sides
2) 5x= -40 : Simplify
3) 5x/5 = -40/5 : Divide both sides
Hope that helps
I believe the answer is 5.9
Answer:
The equation showing this situation is
Step-by-step explanation:
Given : A quadratic equation of the form has one real number solution.
To find : Which could be the equation?
Solution :
A quadratic equation in form has a solution called a quadratic formula in which the roots are one real,two real or no real is determine by discriminant factor.
Discriminant is defined as to determine the number of roots in a quadratic equitation has following rules :
1) If there are two real roots.
2) If there are one real roots.
3) If there are no real roots.
According to question,
A quadratic equation of the form has one real number solution.
So, The equation showing this situation is
Answer:
22°
Step-by-step explanation:
you minus 29 from 7 and that gives 22
Answer:
y = 2x + 150
Step-by-step explanation:
The initial value is $150, this is the y intercept as this is the amount she has at day 0.
To calculate the gradient use change in Y/change in X. the question says that there is an increase of $2 each day so the gradient is 2.
Since y = mx + c we can replace m and c for 2 and 150 to get y = 2x + 150
