Answer:

-37m+6

Step-by-step explanation:

mkay so when working with simplifying any expressions like that, you wanna start with getting rid of your brackets. To do that, you simply take the number directly outside the bracket and you multiply it by everything inside. Let's take -9(m+2) first. You have to multiply everything inside the bracket by -9, so you have -9*m and -9*2, so you end up with -9m and -18. Now you do that to the second part of the equation (4*6 and 4*-7m) and you end up with 24 and -28m. Now you join all your terms together, and you have -9m-18+24-28m. Now all you do is add like terms (so -9m + -28m and -18+24) and you end up with a simplified expression of -37m+6. I hope this helped a little :)).

A florist prepares an order of daisies and roses. For every 5 daisies she orders 2 roes. What 2 equations show the relationship

Vsevolod [243]

Answer:

$d = 2.5r$ and $r = \frac{d}{2.5}$

Step-by-step explanation:

Given

5 daises to 2 roses

Required

Determine the relationship between them

The question shows a direct proportion between number of daises and roses.

i.e.

$d\ \alpha\ r$

Where d = daises and r = roses

Convert the above expression to an equation

$d = kr$

Make k the subject

$k = \frac{d}{r}$

When d = 5 and r = 2;

$k = \frac{5}{2}$

$k = 2.5$

So, the first relationship between d and r can be gotten by substituting 2.5 for k in d = kr

So:

$d = 2.5 * r$

$d = 2.5r$ ----------- (1)

Make r the subject in (1)

$r = \frac{d}{2.5}$ ------------------------(2)

Hence, the relationships between d and r are:

$d = 2.5r$ and $r = \frac{d}{2.5}$

Question 6( Multiple Choice Worth 1 points)

Lynna [10]

Answer:

y = 1

Step-by-step explanation:

A line with a slope of zero is a horizontal line parallel to the x- axis.

The equation of a horizontal line is

y = c

where c is the value of the y- coordinates the line passes through

The line passes through (0, 1) with y- coordinate of 1, thus

y = 1 ← is the equation of the line
