Answer:
.5 years
Step-by-step explanation:
52 weeks = 1 year
26 weeks * 1 year/52 weeks = .5 years
Answer:
x=7
Step-by-step explanation:
97 = 10x + 27
97 - 27 = 10x
70 = 10x
70/10 = x
7=x
Answer:
What you need to consider is what multiplied by 2 results in a/2. This number is the coefficient of a.
We can easily see that a/2 = 1/2 * a and therefore the coefficient is 1/2.
Let the variable be x
A number isn’t given so pick any number.
Let’s use 10
Set up the equation to get:
X + 10 = -8
Solve for the variable by subtracting 10 from both sides:
X = -18
Let the variable be y and pick any number, let’s use the number 2.
Equation: 2 x y = 4/5
Solve for y by dividing both sides by 2:
Y = 2/5
Answer:
Yes, at positive x-coordinates.
Step-by-step explanation:
Finding the equation for g(x):
Slope = (3-6)/ (1-0) = -3
y-intercept = y value when x = 0 = 6.
So g(x) = -3x + 6
Solve them simultaneously:
x^2 + y^2 = 16
g(x) : y = -3x + 6
Substitute for y in the first equation:
x^2 + (-3x + 6)^2 = 16
x^2 + ( 9x^2 - 36x + 36) = 16
10x^2 - 36x + 20 = 0
5x^2 - 18x + 10 = 0
x = [-(-18) +/- sqrt ( (-18)^2 - 4 * -18 * 10)] / (5*2)
= ( 18 +/- sqrt 124 )/ 10
= (1.8) +/- 1,114
These 2 roots are both positive.
