Answer:
y = -4/5x - 5
Step-by-step explanation:
4x + 5y = 45
we need to write it in slope intercept form, so:
5y = -4x + 45
y = -4/5x + 45/5
y = -4/5x + 9
The line is parallel so the slope will be -4/5x, point ( -5 -1 )
y = mx + b
-1 = -4/5(-5)+b
-1 = 4 + b
-1 - 4 = b
-5 = b
y = -4/5x - 5

find the ratio of1 kg55gram
Answer:
200 : 11
Step-by-step explanation:
The quantities in the ratio must have the same units, thus ratio is
1 Kg : 55 g
= 1000 g : 55 g ← both in grams ( divide both quantities by 5 )
= 200 : 11

Answer:

Step-by-step explanation:
To find the length of web we can use the Pythagoras theorem. In order to find the length of web, we first need to find the length between the corners of the 6 feet length and the 10 feet length. This is because the Pythagoras theorem requires a right-angled triangle, which we can form using 8 as the shortest side, the bottom diagonal as the 2nd side and the strand of web as the hypotenuse.
To find the bottom diagonal we first need to use the lengths of 6 and 10 to use the pythagoras theorem.
[tex]a^{2}+b^{2}=c^{2}[/tex]
[tex]6^{2} +10^{2} =c^{2} \\36+100=c^{2} \\136=c^{2}\\\sqrt{136} =c\\c=11.662[/tex]
(3dp)
Now that we have found the length of the bottom diagonal to be 11.662, we can use this length and the 8 we are given to find the strand of web.
[tex]a^{2}+b^{2}=c^{2}[/tex]
[tex]11.662^{2} +8^{2} =c^{2} \\136+64=c^{2}\\200=c^{2}\\\sqrt{200} =c\\c=14.14[/tex]

20. Matt is selling chocolate bars to make some extra money. In the first week of selling, he sold 2x2 + 3x − 1 chocolate bars. In the second week of selling, he sold 3x2 − 2x + 3 chocolate bars. If x = 2, how many chocolate bars did he sell in total over the two weeks?
Answer: 24
Step-by-step explanation:
Chocolate bars sold in first week:
= 2x² + 3x − 1
where x = 2
= 2x² + 3x − 1
= 2(2)² + 3(2) − 1
= (2×4) + 6 - 1
= 8 + 6 - 1
= 13
Second week
= 3x² - 2x + 3
= 3x² - 2x + 3
= 3(2)² - 2(2) + 3
= 12 - 4 + 3
= 11
Total chocolate sold = 13 + 11 = 24
solve the inequality 2(x+5)>8 ?
Answer:
2(x+5)>8
Step-by-step explanation:
=
x>-1
hope that's it
Hi!
I can help you with joy!
No worries, we can solve this inequality easily. :)
First of all, let's use the Distributive Property and distribute 2:
[tex]\rm{2(x+5)>8[/tex]
[tex]\rm{2x+10>8[/tex]
Now, move 10 to the right, using the opposite operation:
[tex]\rm{2x>8-10[/tex]
Subtract:
[tex]\rm{2x>-2[/tex]
Final Step: Divide both sides by 2.
[tex]\rm{x>-1[/tex] (Answer)

Answer:

Step-by-step explanation:
Customers of a phone company can choose between two service plans for long distance calls. The first plan has an $18 monthly fee and charges an additional $0.08 for each minute of calls. The second plan has a $10 monthly fee and charges an additional $0.12 for each minute of calls. For how many minutes of calls will the costs of the two plans be equal?
Answer:
The costs of the two plans would be equal with 200 minutes.
Step-by-step explanation:
From the information given, you can write the following:
18+0.08x=10+0.12x, where x is the number of minutes of calls
Then, you can solve for x:
18-10=0.12x-0.08x
8=0.04x
x=8/0.04
x=200
According to this, the answer is that the costs of the two plans would be equal with 200 minutes.

b) What is your score?
Answer:
A it is addition
B it is 97
Answer:
1,104 points
Step-by-step explanation:
First I figured out how many seconds it took to finish the game (132)
Then I figured out how many points he got by multiplying 30x50=1,500
After that, I multiplied 3 and the number of seconds that it took to finish the game (3x132) and that gave me the answer of 1,104 points

The formula c = 5p + 220 relates c, the total cost in dollars of hosting a birthday party at a skating rink, to p, the number of people attending. If Allie's parents are willing to spend $345 for a party, how many people can attend? The number of people that can attend the party is
Answer:
25 people
Step-by-step explanation:
c = 5p + 220
345 = 5p + 220
-220 -220
125 = 5p
/5 /5
25 = p

On the number line, a point was moved from -7 to -3. Which of the following problems describes this move?
-7 + 4 = -3
-7 + 3 = -4
-7 - 3 = -10
-7 - 4 = -3
Answer:
choice 1) -7 + 4 = -3
Step-by-step explanation:
Since -3--7 = 4, -3 = -7 + 4, -7 = -3-4
4 greater than -7 is 3.

Pls solve and show steps hurry pls !!!!
Answer:
move 5m over the sign so it is like this m-5m>-4 subract it will be-4m>-4 divide both sides by-4 m=1 negative divided by a negative is a positive
the answer is m<1
I subtracted 5 from both sides to get m-5m>-4
I simplified it to -4m>-4
divided both sides by -4 and got m<1 as the answer
