Write an equation of the line with a slope of -3 and a y-intercept of 0
Answer:
-3/9=07+90
Step-by-step explanation:
Answer: y = 0x+3 or y = 3
The slope is 0 and the y intercept is 3. So m = 0 and b = 3.
Plug those into y = mx+b to get y = 0x+3, and that simplifies to y = 3.
This graphs out a horizontal line that passes through the two points (0,3) and (1,3).

Shauna buys a full golf club set for $1,145.87 on a 6 month installment plan. If her monthly
payments are $245.82. How much is the finance charge?
Answer: $329.05
Step-by-step explanation:
Since she pays $245.82 monthly and she is paying for 6 months, the amount paid will be:
= $245.82 × 6
= $1474.92
Since she buys the full golf club set for $1,145.87, then her finance charge will be:
= $1474.92 - $1,145.87
= $329.05
The finance charge is $329.05

A charity is selling brooms to raise funds. Each box has 10 brooms. Each broom is sold for $ 15 . If the charity earns $ 50 profit for each box of brooms, how much does each box of brooms cost the charity, in dollars?
Answer:
Total cost= $100
Step-by-step explanation:
Giving the following information:
Each box has 10 brooms. Each broom is sold for $ 15
The charity earns $ 50 profit for each box of brooms.
First, we need to calculate the total revenue per box:
Total revenue per box= 10*15= $150
Now, the total cost:
Total cost= total revenue - total income
Total cost= 150 - 50
Total cost= $100

Tell whether x and y
are proportional. If so, find the constant of proportionality.
8 = xy
Answer:
Step-by-step explanation:
y is inversely proportional to x; if x increases, y decreases.
Without more info it is not possible to find the constant of proportionality. Recheck the original numerical values. Think: 8 = kxy. You need to know x and y to find the value of k.
4.
Which equation is an identity?
A. 5y + 5 = 5y – 6
B. 8 – (6v + 7) = –6v – 1
C. 3w + 8 – w = 4w – 2(w – 4)
D. 6m – 6 = 7m + 9 – m
Answer: C. 3w + 8 – w = 4w – 2(w – 4)
(3w - w) + 8 = 4w - 2w -2(-4)
2w + 8 = 2w + 8

Grace used 1,000 milliliters of apple juice to make one batch of fruit punch. How many liters of apple juice does Grace need to triple the recipe?
Answer: 3 L
Step-by-step explanation:
Given
Grace uses 1000 mL of apple Juice to make one batch of fruit punch
If she triples the recipe, then the Juice used is also tripled i.e.
[tex]\Rightarrow 3\times 1000=3000\ mL[/tex]
In littres, it is [tex]3000\ mL=3\ L[/tex]

Liz goes on holiday to South Africa
Liz wants to change £850 into south african rand
she wants to get as many 200 rand notes as possible
The exchange rate is £1=18.53 rand
Work out the greatest number of 200 rand notes that liz can get for £850
Answer:
82 notes
Step-by-step explanation:
The computation is shown below:
Given that
£1= 18.53 rand
and since Linz has £850 so he would get the equivalent of
= $890 × 18.53
= 16,491.7 rands
Now he wants the 200 rand notes so we considered it as the highest note
So, the greatest no of 200 notes would be
= 16,491.7 ÷ 200
= 82.45
= 82 notes

The difference of c and 7 is less than or equal to 17.
| c - 7 | 《 17
- 17 《 c - 7 《 17
add sides 7
- 17 + 7 《 c - 7 + 7《 17 + 7
simplification
- 10 《 c《 24
Answer:
c - 7 ≤ 17
c ≤ 24
Step-by-step explanation:
The difference of c and 7 can be written as c - 7 or 7 - c.
Now, since c - 7 is less than or equal to 17, you need to add ≤ to imply that it's less than or equal to 17.
As always, write the 17 on the other side. Now you have an inequality.
If you just need the equation, it's c - 7 ≤ 17.
But if you want to solve for c, it would be c ≤ 24.
(bring the like terms together and isolate c.)

City A and City B are 540 miles apart on a map. The scale on the map is 1inch:60 miles. How many inches apart on the map should City A and City B measure. Explain how you would solve this problem. What would the final answer be?
Answer: 9 inch
Step-by-step explanation:
Given
Distance between city A and city B is 540 miles
Scale on the map is 1 inch: 60 miles i.e. 1 inch on the map is equivalent to 60 miles in the real situation
suppose the distance between city A and B on the map is x
[tex]\therefore \dfrac{1}{60}=\dfrac{x}{540}\\\\\Rightarrow x=\dfrac{540}{60}=9\ in.[/tex]
Therefore, the distance between city A and B is 9 in.

Tanya has a $50 gift card to spend on Amazon. She wants an airpod case cover for $12.
She also wants to buy some bracelets for $9.50 each. How many bracelets can she buy
without going over?
Answer:
She can buy 3 bracelets.
Step-by-step explanation:
$50 (Total price) - $12 (Airpod case) = $38
$38 - $9.50 (Bracelets) = $28.5
$28.5 - $9.50 = $19
$19 - $9.50 = $9.5

Hello! Could y’all please explain why this is Decay and not growth?
Answer:
This is an Exponential Decay
Step-by-step explanation:
A = 1200(0.85)⁶
The above expression is an Exponential Decay because 0.85 is less than 1
The formula for Exponential Decay
= y = a (1 - r)^t
We equate both equation together
Where
a = 1200
1 - r = 0.85
t = 6
Solving for r
1 - r = 0.85
r = 1 - 0.85
r = 0.15
Converting to Percentage
r = 15% decay rate
