5x + 7 = 27

5x = 27 - 7
5x = 20
x = 20 ÷ 5
x = 4

2p - 15 = 35

2p = 35 + 15
2p = 50
p = 50/2
p = 25

How do you do this question?
Bess [88]

"T<u>he function is decreasing":</u>

This means the slope of the function will be negative at the given point.  Anywhere the line is going down, from left to right, is decreasing.  This eliminates choices A and C.

<u>"The function is concave down":</u>

This means the curve of the function will be open down (think of an upside down u).  This eliminates choice E.

<u>"f(x)>0":</u>

This is anywhere the curve is above the x axis.  This eliminates choice D.

The answer is Choice B) x=2.

Hope this helps!!

URGENT will give brilliant mark For the reaction 2Na + Cl2 ------ 2NaCl, how many grams of sodium chloride can be produced from
SVETLANKA909090 [29]

Answer:

825 g

Step-by-step explanation:

Here's my work:

500g Cl2 l   1mol Cl2  l  2 mol NaCl   l  58.5 g NaCl

                l   71 g Cl2    l  1 mol Cl2      l    1 mol NaCl  

= 823.94  - the rounding can be a little off

The first thing you have to do is convert the 500 g of Cl2 into moles.  So you get the mass of Cl which is 35.5, but Cl is diatomic by itself so you multiply 35.5 x 2 and get 71.   now on the third column you are comparing the mol ratios of the equation.  The equation is 2Na + Cl2 ---> 2NaCl, so you see that there is no coefficient in front of Cl2 so that means there is 1 mol, and then you see that in the product there is a  coefficient of 2 in front of NaCl so that means there is 2 moles.  Then finally you have to convert the moles backs into grams where you just add the masses of Na and Cl .  You multiply across the top  and then divide that number by the bottom row.

Find an equation for the line with the given properties. Express your answer using the general form or the slope-intercept form
Damm [24]

Answer:

y=-3x+4

Step-by-step explanation:

To get the equation in the slope-intercept form first, put the equation in slope-point form using the information given. The slope-point form is y-(-2)=-3(x-2). Then solve for y.

Distribute -3 to (x-2),

y-(-2)=-3x+6

Then, add -2 to both sides,

y=-3x+4

This is your final answer; the slope is -3 and the y-intercept is 4. There are also a few other ways to solve but I find this the easiest.

Monthly Loan Payments = 225 for  months = 13,500.00 for five years

This amount doesn't equal the principal so the problem could be worded incorrectly.
