Instructions: Convert this problem into y=mx+b form
Question: 3x+y=0
Answer:
[tex]y=3x[/tex]
Step-by-step explanation:
[tex]Ax+By+C[/tex] ⇒ [tex]y=mx+b[/tex]
[tex]3x+y=0[/tex]
Since there are no coefficients on the [tex]y[/tex], you can convert the equation in one step.
Subtract [tex]3x[/tex] from both sides
[tex]y=3x+0[/tex] [tex]or[/tex] [tex]y=3x[/tex]

To determine what effect the salespeople had on purchases, a department store polled 700 shoppers as to whether or not they had made a purchase and whether or not they were pleased with the service. Of those who had made a purchase, 130 were happy with the service and 119 were not. Of those who had made no purchase, 142 were happy with the service and 309 were not.
Find the probability that a shopper who was happy with the service had made a purchase (round off to the nearest hundredth).
Answer:
This problem has been solved: ... a department store polled 700 shoppers regarding whether or not they made a purchase and whether or not they were pleased ... Of those who made no purchase, 201 were happy with the service and 215 were not. ... We know that number of event of a purchase and a happy with service is.

303÷(−5) jj.ljl≥hk.;h÷/j
Answer:
30³÷(−5) = -6y²
Step-by-step explanation:
We need to find the value of the given expression :
30³÷(−5)
It can be written as :
[tex]\dfrac{30xy^3}{(-5xy)}=\dfrac{30}{-5}\times \dfrac{xy^3}{xy}\\\\=-6\times y^2\\\\=-6y^2[/tex]
So, the value of the given expression is [tex]-6y^2[/tex].
The image shown is an object formed from a cylinder and spherical hemisphere. The radius of the base is 7 cm and the height of the cylinder is 10 cm
(π = 22/7). The volume of the object is ....
A. 2258,67 cm3
B. 2618,33 cm3
C. 2926,67 cm3
D. 2977,33 cm3
Answer:
Volume = 2,258.67 cm³
Step-by-step explanation:
Volume of the object = volume of hemisphere + volume of cylinder
= ⅔πr³ +πr²h
Where,
π = 22/7
r = 7 cm
h = 10 cm
Volume = (⅔*22/7*7³) + (22/7*7²*10)
Volume = 2,258.67 cm³

the TV Margaret wants cost $270 This week only, the TV is discounted by 25%. Margaret must pay 6% sales price. which saves the most money?
A. Taking the discount first then adding on the sales tax
B. Adding on the sales tax first and then taking the 25% discount
C. Both methods save the same amount of money
Answer:
C
Step-by-step explanation:
Method A:
270 decrease 25% =
270 × (1 - 25%) = 270 × (1 - 0.25) = 202.5
202.5 increase 6% =
202.5 × (1 + 6%) = 202.5 × (1 + 0.06) = 214.65
Method B:
270 increase 6% =
270 × (1 + 6%) = 270 × (1 + 0.06) = 286.2
286.2 decrease 25% =
286.2 × (1 - 25%) = 286.2 × (1 - 0.25) = 214.65

Step-by-step explanation:
Dialation means to multiply, so u would multiply the point where D is so in the graph it shows D is on 2, -2 so you would multiply 2 by 1/2 and -2 by 1/2 which would give you (1, -1)
Ayden and his children went into a grocery store and where they sell peaches for $0.75 each and mangos for $1.75 each. Ayden has $20 to spend and must buy no less than 16 peaches and mangos altogether. If Ayden decided to buy 7 mangos, determine the maximum number of peaches that he could buy.
Answer:
he can buy 10 peaches.
Step-by-step explanation:
7 mangoes will be 12.25. so you subtract his original money(20) from 12.25 which gives you 7.75. then divide 7.75 by 0.75(cost of a peach) and your answer will be 10(rounded off).

What is the slope of the line?
what is the factored form of -4/5(30x - 40) + (42x + 4)?
Answer:
18(x + 2)
Step-by-step explanation:
-4/5 ( 30x - 40) + (42x + 4) = -24x + 32 + 42x + 4 = 18x + 36 = 18(x + 2)
Answer:
18x+36
Step-by-step explanation:
1. Simplify \frac{4}{5}(30x-40)54(30x−40) to \frac{4(30x-40)}{5}54(30x−40).
-\frac{4(30x-40)}{5}+42x+4−54(30x−40)+42x+4
2. Factor out the common term 1010.
-\frac{4\times 10(3x-4)}{5}+42x+4−54×10(3x−4)+42x+4
3. Simplify 4\times 10(3x-4)4×10(3x−4) to 40(3x-4)40(3x−4).
-\frac{40(3x-4)}{5}+42x+4−540(3x−4)+42x+4
4. Simplify \frac{40(3x-4)}{5}540(3x−4) to 8(3x-4)8(3x−4).
-8(3x-4)+42x+4−8(3x−4)+42x+4
5. Expand by distributing terms.
-(24x-32)+42x+4−(24x−32)+42x+4
6. Remove parentheses.
-24x+32+42x+4−24x+32+42x+4
7. Collect like terms.
(-24x+42x)+(32+4)(−24x+42x)+(32+4)
8. Simplify.
18x+3618x+36

The ratio x:10 is equilvalent to 9:6. What is the value of x
Answer: x=20/3=6.67
Step-by-step explanation:
To solve proportions, the most useful way is to use [cross multiplication], where we not multiply horizontally but as diagonally.
-----------------------------------------------------------------------------
Given
x:10=9:6
Cross Multiply
9·x=6·10
9x=60
Divide 9 on both sides
9x/9=60/9
x=20/3=6.67

ZX bisects ∠WZY. If the measure of ∠YXZ is (6m – 12)°, what is the value of m?
6
17
90
102
Answer:
The correct answer is option B. 17
Step-by-step explanation:
It is given that, ZX bisects ∠WZY. If the measure of ∠YXZ is (6m – 12)°
To find the value of m
From the figure we can see that, triangle WYZ is an isosceles triangle.
ZW = ZY
Then <YXZ = <WXZ = 90°
It is given ∠YXZ = (6m – 12)°
(6m – 12)° = 90°
6m = 90 + 12 = 102
m = 102/6 = 17
Therefore the value of m = 17
The correct answer is option B. 17
Answer:
its 17. so B
Step-by-step explanation:

(5,-9);slope= -4/3
Write in slope intercept form
Answer:
y = 4/3x-7/3
Step-by-step explanation:
Slope intercept form is y=Mx+b; m=slope & b= y intercept
y=-4/3x+b
Now substitute x & y with the point given
(-9)=-4/3(5)+b
-9= -20/3+b
+20/3 +20/3
-7/3=b
Now substitute this into the original equation
y = 4/3x-7/3

The sum of 6 times a number and 8 times another number is 12. The difference of those numbers is 9. What are the two numbers
Answer:
(x,y): (6 , -3) or (-30/7 , 33/7)
Step-by-step explanation:
6x + 8y = 12
x = y + 9 or y = x+ 9
if x = y+9
6*(y+9) + 8y = 12
14y = -42
y = -3 and x = 6
if y = x+9
6x + 8*(x+9) = 12
14x = -60
x = -30/7 and y = 33/7
A rectangular prism is 3 inches long, 5 inches wide, and has a height of 6 inches. What is its surface area?
63 in 2
90 in 2
120 in 2
126 in 2
Answer:
D) 126 in²
Step-by-step explanation:
A rectangular prism is 3 inches long, 5 inches wide, and has a height of 6 inches. What is its surface area?
The formula for the surface area of a rectangular prism =
A=2(wl+hl+hw)
Where
W= Width = 5in
H = Height = 6 in
l = Length = 3 in
Surface area =
2(5 × 3 + 6 × 3 + 5 × 6) square inches
2(15 + 18 + 30) square inches
2(63) square inches
= 126 square inches (in²)
Option D is correct
