Answer:

Find two points on a graph, and count up/down, and left/right to find rise over run and simplify if you can. For example on this graph the slope from (0,1) to (3,0) is -2/6 or simplify to -1/3 because you go down two and right 6.

Find the exact solution using common logarithms 2^5x+3= 3^2x+1
AfilCa [17]
2^{5x + 3} = 3^{2x + 1}
log_{2}(2^{5x + 3}) = log_{2}(3^{2x + 1})
(5x + 3)log_{2}(2) = (2x + 1)log_{2}(3)
5x + 3 = 1.58(2x + 1)
5x + 3 = 3.16x + 1.58
1.84x + 3 = 1.58
1.84x = -1.42
x \approx -0.77

Help! Need by 10:30 to turn in and I'm confused!
Alecsey [184]

Answer:

8 boxes of tissues

5 bags of cough drops

Step-by-step explanation:

You need to write a system of equations.

x = number of tissue boxes

y = number of cough drop bags

x (number of tissue boxes) + y (number of cough drop bags) = 13 (total number of tissues and cough drops combined.

So, your first equation is

x + y = 13

Then, you need to write the second equation.

(1.69 [cost of 1 tissue box] * [number of tissue boxes]) + (1.19 [cost of one bag of cough drops] * [number of cough drop bags] = 19.47 [total cost of tissues and cough drops]

That's a lot to read, so here's the equation simplified!

1.69x + 1.19y = 19.47

Now, you have two equations:

x + y = 13

1.69x + 1.19y = 19.47

I would solve with the substitution method.

the first equation can be changed to x = 13 - y by subtracting y from both sides.

Then, your two equations are:

x = 13 - y

1.69x + 1.19y = 19.47

Now, you can plug in that value of x into the second equation!

1.69(13 - y) + 1.19y = 19.47

21.97 - 1.69y + 1.19y = 19.47

subtract 21.97 from both sides

-1.69y + 1.19y = -2.5

Add the y values

-0.5y = -2.5

divide both sides by -0.5

so, y equals 5 bags of cough drops

now that you know what y equals, plug it back into your original equation to find x!

x + y = 13

plug in y

x + 5 = 13

x = 8

so, x = 8 boxes of tissues

Hope this helps! Let me know if you have any questions!

(4-3n) 8 simplify the expression
PSYCHO15rus [73]

Answer:32-24n

Step-by-step explanation:

Take 8 and 4 and multiply it and you get 32. Take 8 and 3 multiply or add 8 three times and you get 24 and also add the n so it’s 24n since the n goes no where, and you can’t really subtract a number with a letter with a number or a number with a different letter, you can only subtract or add it if it has the same letter on the number. Hope that helps.
