Hello!
--------------------------------------------------------------------------------------------------------------
19x+5+16x=180
First, add the x's together:
35x+5=180
Now, subtract 5 from both sides:
35x=180-5
35x=175
Divide both sides by 35 to isolate x:
x=5

Gavin needs $80 to buy a fish tank. He has saved $8 and plans to work as a babysitter to earn $9 per hour. Which inequality shows the minimum number of
hours, n, that Gavin should work as a babysitter to earn enough to buy the fish tank?
8 + 9n ≥ 80, so n ≥ 8
8 + 9n ≤ 80, so n ≤ 8
9n ≥ 80 + 8, so n ≥ 9.8
9n < 80 + 8. so n < 9.8
so the answer would be 8+9n≥80. The reason why is because he has $80 and he saved $8 and he earned $9 for each hour but we do not know how many hours so that is why it is n. and it says minimum so u might think that it might be ≤ but my sister says to think the opposite so the symbol will be ≥.
Hope this helps ^_^
question 8

You are doing chores to earn your allowance. For each chore you do, you earn $5. You are saving up to buy a $100 lego set. How many chores would it take you to earn $100?
Answer:
It would take 20 chores.
Step-by-step explanation:
1 chore = $5
=> 1 x 20 = $100
=> 20 chores = $100
Therefore, it would require me 20 chores to save $100 and buy that Lego set.
Hoped this helped.

Given that f ( x ) = 8 x + 5 f ( x ) = 8 x + 5 and g ( x ) = 3 − x 2 g ( x ) = 3 - x 2 , calculate f(g(0))
Answer:
29
Step-by-step explanation:
g(0)=3-2(0)
= 3
f(3) = 8(3)+5
f(3) = 29
HELPPP!!!! Both questions are incredibly confusing to me !!!!!
Answer:
Step-by-step explanation:
I'm going to start with problem 3. You need to become familar with the kind of tricks teachers play on you.
Problem 3 depends on getting RS = RW.
RT = RT Reflexive property
<STR = <WTR A straight line having 1 rt angle actually has 2
ST = TU They are marked as equal
Triangle STR=Triangle WTR SAS
RS = RW Corresponding parts of = triangles are =
8x = 6x + 5 Subtract 6x from both sides
8x -6x = 6x - 6x + 5 Combine
2x = 5 Divide by 2
2x/2 = 5/2
x = 2.5
RU = 6*2.5 + 5
RU = 15 + 5
RU = 20
Now we can play with Question 4.
This question depends on the method used in three, although not entirely.
What you need to know is that W is on RT when you take a ruler and make RT longer. You can put W anywhere as long as it is on RT when it is made longer.
Directions
Make RT longer. Draw down and to your right.
Put a point anywhere on the length starting at T. Label this new point as W. There's your W. It goes anywhere on the part of RT made longer.
Draw UW.
Label UW as 8
Now draw another line from S to W. Guess what? By the methods used in question 3, it's also 8. So SW = 8
TW = TW Reflexive
<UTW = STW Same reason as in 3. UtW is a right angle
UT = ST Given (the marking tells you so.
ΔUTW = ΔSTW SAS
UW = SW Corresponding parts of = triangles are =
SW = 8

what is the value of the expression 2/5m−1/3 when m = 3?
Answer:
13/15
Step-by-step explanation:
I took the quiz and solved it out. I would give further explaination but it is kinda hard to do that in text form. Have a nice day!
The value of the expression if m = 3 is 13/15
Given the expression as shown below:
2/5 m - 1/3If the value of m = 3, hence the expression will become;
2/5(3) - 1/3
6/5 - 1/3
Find the LCM
6/5 - 1/3 = 3(6)-5/15\
6/5 - 1/3 = 18-5/15
6/5 - 1/3 = 13/15
Hence the value of the expression if m = 3 is 13/15

find the limiting value using L hospital
Answer:
-1
Step-by-step explanation:
The expression evaluates to the indeterminate form -∞/∞, so L'Hopital's rule is appropriately applied. We assume this is the common log.
d(log(x))/dx = 1/(x·ln(10))
d(log(cot(x)))/dx = 1/(cot(x)·ln(10)·(-csc²(x)) = -1/(sin(x)·cos(x)·ln(10))
Then the ratio of these derivatives is ...
lim = -sin(x)cos(x)·ln(10)/(x·ln(10)) = -sin(x)cos(x)/x
__
At x=0, this has the indeterminate form 0/0, so L'Hopital's rule can be applied again.
d(-sin(x)cos(x))/dx = -cos(2x)
dx/dx = 1
so the limit is ...
lim = -cos(2x)/1
lim = -1 when evaluated at x=0.

I find it useful to use a graphing calculator to give an estimate of the limit of an indeterminate form.
Help finding surface area

need help urgently vvvvvvv
Step-by-step explanation:
you understand coordinates and how to find them in the chart, yes ?
because I can't draw here, I can only give you the points through which the line has to go.
one point is, of course, (2, -3).
to find another good point we use the slope 3/4.
the slope is the ratio of y change/x change when going from one point to another.
so, we find another point with integer coordinates by e.g subtracting the slope units from the point (addition would also work) :
the other point on the line would be
(2 - 4, -3 - 3) = (-2, -6)
and then you draw a line that goes through both points.
which is bigger 11/18 or 5/14
Among the fractions given in this question 11/18 and 5/14, the largest fraction is: 3/5.
Step-by-step explanation:To find out which fraction is the largest, just divide the numerator by the denominator of the ratio and make the comparisons between them, thus defining which is the largest by decimal places or the largest number.
Resolution:[tex]\large \sf \dfrac{11}{18} \rightarrow 11\div18\rightarrow 0{,}61111111111[/tex]
[tex]\large \sf \dfrac{5}{14} \rightarrow 5\div14\rightarrow 0{,}35714285714[/tex]
Conclusion:We can conclude that the largest fraction, being between 11/18 and 5/14, is 11/18.

Find the slope of the line y=5x+4

Answer:
5 is the slope of the line
Answer:
slope = 5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 5x + 4 ← is in slope- intercept form
with slope m = 5
A line that includes the point (-1,5) has a slope of 4. What is its equation in slope-intercept
form?
Answer:
y=4x+9
Step-by-step explanation:
The slope intercept form is [tex]y=mx+b[/tex]
So m=4 and we plug it into the equation [tex]y=4x+b[/tex]
Since there are x point is -1 and y point is 5 we plug those in replacing the corresponding variables [tex]5=4(-1)+b[/tex]
So the equation becomes [tex]5=4+b[/tex]
We add 4 to both sides [tex]5=4+b\\+4=+4[/tex] so 9 equals b
Then we rewrite the whole equation as [tex]y=4x+9[/tex]
