1/5(25-5a)=4-a
⇔5-a=4-a
NO SOLUTION
Answer:
The results are given by:___________.
the equation, y = ax+b.
where a = the slope of the line and b is the intercept or the value of Y when X = 0.
Step-by-step explanation:
The simple linear regression is a model for estimating the relationship that exists between an independent variable and a dependent variable. The model uses a straight line for two quantitative variables. With a scatter graph, the line of best fit is given as the equation, y = bX + a. This equation determines the values of b and a for a dataset of two variables. It can also be used to estimate the value of Y for a given value of X.
Answer:
a
Step-by-step explanation:
Answer:Let x = pay per hour as a carpenter and y = pay per hour as a blacksmith
Last week she worked 12 hours as a carpenter
earning 12x dollars
and 20 hours as a blacksmith
earning 20y dollars
and earned a total of $860
and those two things add up to 860.
Do the same with the other sentence, giving you a second equation.
Step-by-step explanation:
Answer:
The rule could cost 24 cents at most.
Step-by-step explanation:
Let x cents be the price of the ruler.
Alice is 22 cents short, so Alice has x - 22 cents.
Betty is 3 cents short, so Betty has x - 3 cents.
When they combine their money they have
x - 22 + x - 3 = 2x - 25 cents.
This amount is still not enough, so
Solve this inequality:
The rule could cost 24 cents at most.
