Answer:

Equation F can be written as 5b + 1 = 3b + 4

Step-by-step explanation:

A set of equations is given below:

Equation E: a = 5b + 1

Equation F: a = 3b + 4

In substitution method we solve the equation for a variable and substitute it in other equation

Given a= 5b +1

Also equation F : a= 3b+4

both equation have 'a' on the left hand side

So we substitute 5b+1 for 'a' in second equation

Substitute 5b+1 in the place of 'a' in Equation F

Equation F can be written as 5b + 1 = 3b + 4

What is the slope of the line with the equation y-3=-1/2(x-2)?

torisob [31]

Answer: $-\frac{1}{2}$

Step-by-step explanation:

$y -3 = -\frac{1}{2}(x-2)$

Write as slope-intercept form y = mx + b, where m is the slope and b is the y-intercept.

$y-3=-\frac{1}{2}x + 1$

$y = -\frac{1}{2}x+4$

Therefore, the slope is $-\frac{1}{2}$ .

jester has a piece of wood measuring 1 and 2/3 m.he needs to cut in pieces measuring 3/4 m long.how many pieces of wood did jest

sveticcg [70]

Answer:

2 pieces

Step-by-step explanation:

Given

$Length = 1\frac{2}{3}m$

$Pieces = \frac{3}{4}m$

Required

Calculate the number of pieces

To do this, we have to divide the length of the wood by the length of each piece.

Represent this with x

$x= \frac{Length}{Pieces}$

$x= 1\frac{2}{3}/\frac{3}{4}$

Convert mixed numbers to improper fraction

$x= \frac{5}{3}/\frac{3}{4}$

Change division to multiplication

$x= \frac{5}{3}*\frac{4}{3}$

$x= \frac{20}{9}$

$x = 2.22$

$x = 2$

Kylie is comparing the cost of two housekeeping companies, DoItRight and CleanIt. The table describes the costs for DoItRight.

abruzzese [7]

Answer:

First, find the cost function of DoItRight Housekeeping:

Slope(m) = cost per hour = $\frac{y_{2}-y_{1}}{x_{2}-x_{1}}=\frac{44-26}{3-1.5}=\frac{18}{1.5}=12$

The y-intercept(b), representing the initial cost, can be calculated by substituting in values to the function:

$f(x)=12x+b\\26=12(1.5)+b\\b=26-18=8$

Therefore, the function for two companies are:

The function for DoItRight is $f(x)=12x+8$
The function for CleanIt is $g(x)=10x+16$

When comparing the two functions, it's shown how CleanIt has a greater y-intercept than DoltRight, meaning that CleanIt has a greater initial cost than DotRight. The y-intercept is when the graph intercepts the y-axis, therefore, the coordinates there would be (0, y-value), which, in this case for CleanIt company, will be (0, 16). While CleanIt has a greater y-intercept(initial cost), DoItRight has a greater slope, meaning they cost more per hour.
