Step-by-step explanation:
y = 10x - 32
To find the x intercept set y =0 and solve for x
0 = 10x -32
Add 32 to each side
32 = 10x
Divide by 10
32/10=10x/10
3.2 = x
To find the y intercept set x =0 and solve for t
y = 10*0 -32
y= -32
Answer:
y.(0,-32)
x.(3.2,0)

John went to the bakery and bought
several dozen donuts and several
dozen bagels. The donuts cost $9
per dozen and the bagels were $8
per dozen. If he spent a total of
$101 for 12 dozen items, how many
donuts did he buy?
Answer:
5 dozen Donuts
7 dozen bagels
Step-by-step explanation:
5 * 9 = 45
7 * 8 = 56
56 + 45 = 101
Answer: He bought 5 dozen donuts
Step-by-step explanation:
d + b = 12 where d is the number of donuts and b is the number of bagels.
9d + 8b= 101 now solve the two equations using the elimination method
-9d - 9b =-108
9d + 8b = 101
-1b = -7
b = 7
9d + 8(7)= 101
9d + 57 = 101
9d = 45
d= 5

Answer:
x = 12.81
Step-by-step explanation:
Because this is a right triangle, we can use the Pythagorean Theorem to solve for x. We have 10² + 8² = x² → 100 + 64 → x² = 164 → x = 12.81. Hope this helps!
Step-by-step explanation:
using Pythagoras relationship
[tex] {x}^{2} = {10}^{2} + {8}^{2} \\ {x}^{2} = 100 + 64 \\ {x}^{2} = 164 \\ x = \sqrt{164} \\ x = 12.806 \\ x = 12.8[/tex]

answer for -2x-41=5x-6
Answer:
x=-5
Step-by-step explanation:
-2x-41=5x-6
-35=7x
-5=x
Hello there!
-2x - 41 = 5x - 6
Move the 41 over by adding 41 to both sides.
-2x = 5x + 35
Move the 5x by subtracting it from both sides.
-7x = 35
Divide by -7 to get x.
-7/-7 = 35/-7
x = -5
Therefore, x would equal -5.

Element X decays radioactively with a half life of 12 minutes. If there are 510 grams of Element X, how long, to the nearest tenth of a minute, would it take the element to decay to 11 grams?
Answer:
t = 66.4 minutes ( to the nearest tenth of a minute)
it would take the element 66.4 minutes to decay to 11 grams
Step-by-step explanation:
Given;
Initial amount N = 510 g
Final amount Nt = 11 g
Half life t(1/2) = 12 minutes
The amount of time t required for the Element X to decay from N to Nt can be written as;
t = ln(Nt/N) ÷ -λ .....1
Where;
λ = decay constant
λ = ln(2)/t(1/2)
Substituting λ, equation 1 then becomes;
t = ln(Nt/N) ÷ -(ln(2)/t(1/2))
Substituting the values;
t = ln(11/510) ÷ -(ln(2)/12)
t = −3.8365 ÷ -0.05776
t = 66.419
t = 66.4 minutes ( to the nearest tenth of a minute)
Which relation is not a function?
Answer:
D.
Step-by-step explanation:
For a relation to be a function, one input cannot have multiple outputs.
In D, we can see that the input x = 1 will yield y = 4 and y = 1. So which one is it?
We cannot determine that, so this relation is not a function.

x = 2y - 7
4x + y = 71
Answer:
(15, 11)
Step-by-step explanation:
(I'm assuming you are solving for x and y.)
Plug in the x equation:
4(2y - 7) + y = 71
8y - 28 + y = 71
9y - 28 = 71
9y = 99
y = 11
Then plug that answer into the other equation:
x = 2(11) - 7
x = 22 - 7
x = 15
You can check by doing the following to make sure you are right:
15 = 2(11) - 7
15 = 22 - 7
15 = 15
4(15) + 11 = 71
60 + 11 = 71
71 = 71

My Question was The slope of the line shown between the points (-7, -3) and (-4, 0) is equal to its slope between the points (0, 4) and (6, 10).
Which of the following best describes triangle TUV and triangle XYZ?
answer: Triangle TUV is similar to triangle XYZ.
Step-by-step explanation:
Point V is at (-7, -3), and point T is at (-4, 0). So, the slope of the line between (-7, -3) and (-4, 0) is equal to the ratio of UT to VU.
Point Z is at (0, 4), and point X is at (6, 10). So, the slope of the line between (0, 4) and (6, 10) is equal to the ratio of YX to ZY.
Since the slope between (-7, -3) and (-4, 0) is equal to the slope between (0, 4) and (6, 10), the ratio of UT to VU is equal to the ratio of YX to ZY.
Two right triangles are similar if the ratios of two sets of their corresponding sides are congruent. Therefore, triangle TUV is similar to triangle XYZ.

Step-by-step explanation:
You deposit $1200 in an account. The annual interest rate is 3%. How long will it take you to earn $108 in simple interest?
Answer:
Interest = $3,888
Step-by-step explanation:
Formula:
I = prt or I = p · r · t
what it stands for:
I = amount of interest
P = principal amount ($1,200)
R = interest rate (in years)(3% into decimal which would be .03)
T = amount of time (in years)($108)
so:
I = prt
I = (1,200)(.03)(108)
I = $3,888
Interest = $3,888

The perfume company Scents 4 cents is about to release their latest perfume. The manager ordered 3 different perfume bottles customers can choose from. Approximate the volume of perfume each bottle can carry
Image and dimension of each bottle is attached
Answer:
Cyclinder = 572.56 cm³
Sphere = 381.70 cm³
Cone = 190.86 cm³
Step-by-step explanation:
Here, the manager ordered for three different shapes, which are: a sphere, cylinder and a cone. We are told to find the volume of each.
For the cylinder:
Given:
Radius, r = 4.5 cm
Height, h = 9 cm
The formula for calculating the volume of a cylinder is:
V = Base * height
Where base = πr²
= π * 4.5² = 63.62
Therefore,
V = 63.62 * 9
V = 572.56 cm³
For sphere:
Given:
Radius, r = 4.5 cm
Formula for volume of a sphere is:
[tex] V = \frac{4}{3} * \pi r^3 [/tex]
[tex] = \frac{4}{3} * \pi 4.5^3 [/tex]
= 381.7 cm³
For cone:
Given:
Radius, r = 4.5 cm
Height, h = 9 cm
The formula for calculating the volume of a cone is:
V = ⅓ * Base * height
Where base = πr²
= π * 4.5² = 63.62
Therefore,
V = ⅓*63.62 * 9
V = 190.86 cm³
Therefore the volume of perfume each bottle can carry is:
Cyclinder = 572.56 cm³
Sphere = 381.7 cm³
Cone = 190.86 cm³

Let f (x) = 3x − 1 and ε > 0. Find a δ > 0 such that 0 < ∣x − 5∣ < δ implies ∣f (x) − 14∣ < ε. (Find the largest such δ.) What limit does this prove?
Answer:
This proves that f is continous at x=5.
Step-by-step explanation:
Taking f(x) = 3x-1 and [tex]\varepsilon>0[/tex], we want to find a [tex]\delta [/tex] such that [tex]|f(x)-14|<\varepsilon[/tex]
At first, we will assume that this delta exists and we will try to figure out its value.
Suppose that [tex]|x-5|<\delta[/tex]. Then
[tex]|f(x)-14| = |3x-1-14| = |3x-15|=|3(x-5)| = 3|x-5|< 3\delta[/tex].
Then, if [tex]|x-5|<\delta[/tex], then [tex]|f(x)-14|<3\delta[/tex]. So, in this case, if [tex]3\delta \leq \varepsilon[/tex] we get that [tex]|f(x)-14|<\varepsilon[/tex]. The maximum value of delta is [tex]\frac{\varepsilon}{3}[/tex].
By definition, this procedure proves that [tex]\lim_{x\to 5}f(x) = 14[/tex]. Note that f(5)=14, so this proves that f is continous at x=5.

1. Gertrude said her survey showed 2/3 of her math class liked hip hop music. There are 24 students in the class. Is it possible that Gertrude's survey is correct?
My Answer: Yes it's correct because 2/3 = 36 since 24/2=12 and 12*3=36
There are 24 students in the class. Take 2/3 of this to get (2/3)*24 = 16
A more detailed step by step would be
(2/3)*24 = (2/3)*(24/1) = (2*24)/(3*1) = 48/3 = 16
The result 16 is smaller than the original number 24. This is expected because 2/3 is smaller than 1. The key thing here is that the result 16 is a whole number.
You can think of 2/3 as the approximate percentage 66.7%, so you're applying roughly 66.7% to the entire class to get 16 people who like hip hop.
It appears you're thinking in reverse when you went from 24 to 36, because 2/3 of 36 is 24, but not the other way around. Keep in mind there are 24 students total in the class, and we can't go higher than this. We can't say there are 36 people who like hip hop.
So to answer the question, yes it is possible Gertrude's survey is correct because 2/3 of 24 is a whole number.

Option B is the correct answer.
We have,
The best thing Anastasia can do to improve her creditworthiness is to pay down her student loan and credit card debt.
This will lower her credit utilization ratio, which is a significant factor in determining her credit score.
Having a high credit utilization ratio can indicate to lenders that she may be at risk of defaulting on her debts, which could make it more difficult for her to obtain a mortgage or other loans in the future.
Paying down her debts can help improve her credit score and make her a more attractive borrower to potential lenders.
Thus,
The best thing Anastasia can do to improve her creditworthiness is to pay down her student loan and credit card debt.
