Twice the difference of a number and 8 equals 5.
Use the variable b for the unknown number.
Answer:
it's simple it means
2×b-8=5
Answer:
b = 10.5
Step-by-step explanation:
The difference of b and 8 is b - 8 and twice this difference is
2(b - 8) = 5 ← distribute parenthesis on left side
2b - 16 = 5 ( add 16 to both sides )
2b = 21 ( divide both sides by 2 )
b = 10.5
The unknown number b is 10.5

Suppose the population of a town is 100,000 in 2014. The population increases at a rate of 4.5 percent every year. What will the population of the town be in 2020? Round your answer to the nearest whole number.
Answer:
127,000 people by 2020
Step-by-step explanation:
4.5% per year
We have 6 years since 2020-2014=6 years
4.5 • 6 = 27% of 100,000 = 27,000
To find our total population, it would be 100,000+27,000=127,000 people would live there in 2020
This is assuming the birth rate is consistent

Given the complementary angle of y is 43º. Find the supplementary angle of y
Step-by-step explanation:
complementary = adds up to 90 degrees.
supplementary = adds up to 180 degrees.
the complementary angle of y is 43 degrees.
so, y = 90 - 43 = 47 degrees.
the supplementary angle of y = 47 is
180 - 47 = 133 degrees
Hello!
Given the complementary angle of y is 43º.
90 - 43 => 47°
Find the supplementary angle of y
180-43 => 137°

1. y = 1/4x +4 1/4
2. y = -5/9x +7/9
Step-by-step explanation:
The relevant formulas are ...
m = (y2 -y1)/(x2 -x1) . . . . . slope of line through points (x1, y1), (x2, y2)
b = y -mx . . . . . . . . . . . . . y-intercept of a line with slope m through point (x, y)
y = mx + b . . . . . . slope-intercept equation of the line
__
1.Points (3, 5), (-1, 4)
m = (4 -5)/(-1 -3) = -1/-4 = 1/4
b = 4 -(1/4)(-1) = 4 1/4
Equation of the line: y = 1/4x + 4 1/4
__
2.Points (-4, 3), (5, -2)
m = (-2-3)/(5 -(-4)) = -5/9
b = 3 -(-5/9)(-4) = 3 -20/9 = 7/9
Equation of the line: y = -5/9x +7/9
What is a dot product.

What is the domain of f?
Answer:
-7 ≤ x ≤ 7
General Formulas and Concepts:
Algebra I
Coordinate Planes
Domain is the set of x-values that can be inputted into function f(x)Step-by-step explanation:
According to the graph we can see that our x values span from -7 to 7. Since both are closed dot, they are inclusive in our domain:
[-7, 7] or -7 ≤ x ≤ 7
Answer:
A -7<=x<=7
Step-by-step explanation:
Domain is the set of x values which fulfill the function. We can tell from the graph that the x values start from -7 and last to 7. therefore the domain is A
