Answer:
x = -5
Step-by-step explanation:
f(x)= is another way of saying y=
When y is equal to -3...you are looking for a point on the graph where it is -3 on the y-axis..then x is -5.
Look at (-5,-3).
Factor the following expression: x^2+3x
Step-by-step explanation:
Hey there!

Adult tickets are $16 and child tickets are $6. The theater sold a total of 137 tickets for a total of $1772. How many adult tickets did the theater sell
Answer:
95
Step-by-step explanation:
Let x represent the cost of adult tickets for $16
Let y represent the cost of children tickets for $6
x + y = 137...........equation 1
16x +6y = 1772............equation 2
Multiply equation 1 by 16 and equation 2 by 1
16x + 16y= 2192
-
16x + 6y = 1772
10y = 420
y= 420/10
y= 42
Substitute 42 for y in equation 1
x + y = 137
x + 42= 137
x = 137-42
x= 95
Hence 95 adult tickets were sold for $16 and 42 children tickets were sold for $6
Pleaseee helpppp!!!!! I keep getting this answer wrong on the test :(
What is (4/5) / (1/10)
The answer would be 8.
REMEMBER: Keep / Change / Flip
KEEP - 4/5
CHANGE - / to *
FLIP - 1/10 | 10/1
Now you have, 4/5 * 10/1. Just multiple across and you'll get 40/5. Now, divide 40 and 5 and you'll get your answer, 8.
[tex] \frac{ \frac{4}{5} }{ \frac{1}{10} } [/tex]
[tex] \frac{4}{5} \div \frac{1}{10} [/tex]
[tex] \frac{4}{5} \times \frac{10}{1} [/tex]
[tex] \frac{40}{5} [/tex]
[tex]8[/tex]
Help pleaseeeeeeeeeeee.
Answer:
(-10, 9)
Step-by-step explanation:
9x+9y=-9
Use substitution method
9(-10)+9y=-9
Order of operations(PEMDAS)
-90+9y=-9
Add 90 to both sides
(-90+90)+9y= -9+90
9y=81
Divide 9 from both sides
(9/9)y=81/9
y=9
Hope this helps. Have a nice day. May it be filled with joy and happiness. Please, stay safe and wash your hands. Happy Holidays.
Answer:
Step-by-step explanation:
in this case, we already know that x= -10 so we can substitute in the other problem, -10x9 = -90 so now we can get rid of that by adding + 90 on each side making it 9y=81 by this time, we see that both sides are divisable by 9 divide both by nine and you get: 1y=9 from that you can finally answer the question with
x= -10 y= 9
Plz help!! I’m a bit confused
How would you use a table to graph –3x + 4y = 23?
Answer: you would look for y and then once you have y you put it into desemos which is a graphing app and then you get your line
Step-by-step explanation: you would do +3x on both sides with out doing it to the 4y and the. You would get 4y =23+3x and then you divide everything by 4 even the 4y and then you would get y= 23/4 + 3/4x and then you put it into desemos and it will give you it graphed

Mary borrowed $840 from her friend to help pay for a trip. She paid him $40 every
week until the debt was paid.
How many weeks did it take Mary to pay her debt?
A. 40
B. 35
C. 32
D. 21
Answer:
d.21
Step-by-step explanation:
840/40=21
Answer:
21 Weeks
Step-by-step explanation:
$840 ÷ 4 weeks = 21
You can also reverse work this by multiplying $40 by the other choices!
$40 x 40 = $1600
$40 x 35 = $1400
$40 x 32 = $1280
$40 x 21 = $840
As we can see, D is the only answer that makes sense, therefore 21 weeks is the answer.

A student pays for pounds of apples with a $ bill. How much change does the student receive? Answer parts a and b. a. What do you do first to solve the problem? ▼ the number of pounds of apples by the price per pound
A student pays for 8.9 pounds of apples with a 10$ bill. Its $1.09 per pound. How much change does the student receive? What do you do first to solve the problem?
Answer:
$0.299
Step-by-step explanation:
Given that :
Pounds of apple purchased = 8.9 pounds
Price per pounds of apple = $1.09
Bill issued = $10
First, we calculate the total cost of 8.9 pounds of apple :
(Number of pounds * price per pound)
($8.9 * 1.09) = $9.701
Amount of Change :
Bill issued - total cost
$10 - $9.701
= $0.299

Answer:
$3,000 was invested in the account that gained 13%
$17,500 was invested in the account that lost 10%
Step-by-step explanation:
Let the amount in both accounts be x and y
x for the first and y for the second
Adding both is 20,500
x + y = 20,500 •••••(i)
First account earned 13% profit
= 13/100 * x = 0.13x
Second account, a loss of 10%
= -10/100 * y = -0.1y
Total loss of -1,360
This is;
-0.1y + 0.13x = -1,360 •••••••(ii)
From i, x = 20,500-y
Insert this into ii
-0.1y + 0.13(20,500-y) = -1,360
-0.1y + 2665 -0.13y = -1360
-0.23y = -1360-2665
-0.23y = -4025
y = -4025/-0.23
y = 17,500
To get x, we have
x = 20,500 -y
x = 20,500- 17,500
x = 3,000

Find the measure of angle A
Answer:
43°
Step-by-step explanation:
(x + 53)° + (x + 74)° + 73° = 180°
(x + 53 + x + 74)° = 180° - 73°
(2x + 127)° = 107°
2x + 127 = 107
2x = 107 - 127
2x = - 20
x = - 20/2
x = - 10
[tex]m\angle A = (x +53)\degree \\\\
m\angle A = (-10 +53)\degree \\\\
m\angle A = 43\degree \\\\
