Solve the system of equation. Write the solution as a coordinate point.
We can just substitute y = 4x+1 in the second equation.
[tex]6x-2(4x+1)=-3\\6x-8x-2=-3\\6x-8x-2+3=0\\-2x+1=0\\-2x=-1\\x=\frac{1}{2}[/tex]
We know the value of x, substitute x in any equations to get the y-value.
[tex]4x+1=y\\4(\frac{1}{2})+1=y\\2+1=y\\3=y[/tex]
The value of y is 3 and the value of x is 0.5 aka 1/2
Since you want the solution as a point then It's below here.
Nathan had an infection, and his doctor wanted him to take penicillin. Because Nathan’s father and paternal grandfather were allergic to penicillin, Nathan has a 75% chance of having the same allergy. The doctor performed a skin test to see whether Nathan would react to it. The test is 98% accurate. If the test predicts that Nathan is not allergic to penicillin, what is the probability after the test that Nathan is not allergic to the drug?
A.
0.1135
B.
0.2450
C.
0.9423
D.
0.9932
Answer:
im late but if anyone sees this question its 0.9423
Step-by-step explanation:
The test predicting that he does not have the drug and is correct is 0.98 x 0.25.
Predicting that he does not have the drug but is wrong is 0.02 x 0.75
[tex]\frac{ (0.98 * 0.25)}{ (0.98 * 0.25) + (0.02 * 0.75} \\\\=\frac{ (0.245)}{ (0.245) + (0.015)} \\\\= \frac{ 0.245}{ 0.26} \\\\=0.9423[/tex]

f(x) = 2x2 + 1, what is f(x) when x = 3?
0 1
O 7
O 13
O 19
Answer:
f(x) = 19
Step-by-step explanation:
f(x) = 2x2 + 1
f(x) = 2(3)2 + 1
f(x) = 2(9) + 1
f(x) = 18 + 1
f(x) = 19

Urgent!!! 100 points!!! Scientists at the new company bung tested their bungee cords using weights from 0 to 500 pounds. Using the data from testing, they modeled the relationship between the weight on the bungee cord and the length of the cord with the function l = 0.05w + 10 where w is the weight of the cord (in pounds) and l is the length of the cord (in feet). Identify the constant term and explain its meaning in the context of the data.
Answer:
The constant term is the weights rate of change, because the formula never changes.
you can buy 3 apples at the quick stop for $1.29. you can buy 5 apples at shop and save for $2.45. which place is better buy?
Answer:
Quick Stop -
3 apples = $1.29
1 apple = $0.43
Shop -
5 apples = 2.45
1 apple = 0.49
So the quick stop is better!

sophia scored 92 percent in a math test. If the test had 50 questions, how many did she get right?
Answer:
Sophia got 46 questions right.
Step-by-step explanation:
Heres why:
In order to find how much she got right, we put 92% over 100 and make it a fraction so that would be 92/100.
Now, she had 50 questions. So, we will put that over 1. So that would look like this: 50/1.
Finally, we multiply: 92/100 times 50/1.
This equals 4600/100 which equals 46
SO: Sophia got 46 questions right! Hope this helps and plz mark brainliest if you want to! :)

PLEASE HELP ME!!! Choose all of the algebraic expressions that could represent the phrase below.
nine more than the product of 5 times the number of tires t
A. 9 + 5t
B. 5 ▪ t + 9
C. (9 + 5)t
D. (5 × t) + 9
E. 5 + 9t
Answer:
9 + 5t
Step-by-step explanation:
Nine more means 9 plus (9+)
after the 9+, it says 5 times the number of t. That means 5*t, or 5t.
putting them together, you get 9+5t
Answer:
A. 9 + 5t

The completed construction of a regular hexagon is shown below. Explain why AACF is a
30°-60°-90° triangle. Show a picture, please!
Answer:
You can prove that angle C is 30°. This is because we know that angle B is 120° also, and interior angles add to 180°, which makes angle BCF 60°. Then we can divide this by 2 as angle BCF is bisected by AC, so, therefore, angle ACF is 30° as 60 ÷ 2 = 30.
You can then prove angle A is 90°. First, we can find angle BAC because it is part of a triangle, and angles in a triangle add to 180°. This means we can do 30 + 120 = 150, and 180 - 150 = 30° which is angle BAC. Then we do 120 - 30 = 90, as the whole of angle BAF is 120°.

Help plz i have only tonight 11;59
Answer:
Base = 16, height 64
Step-by-step explanation:
It's a triangle so u have to multiply it with 1/2 or divide by 2, x will equal both height and base:
(1/2)4x^2 = 512
Multiply 2 to both sides
4x^2 = 1024
divide both sides by 4
x^2 = 256
[tex]\sqrt{x^2}[/tex] = [tex]\sqrt{256}[/tex]
x = 16, base is 16 and height is 16(4) = 64
Alright this took me some time but I got it now, u might think why 16 and 64? 16 times 64 is not 512, but the equation for a triangles area is [tex]\frac{b h}{2}[/tex] or b·h·1/2 , so if u plug the numbers into the equation it will equal 512:
16 · 64 · 1/2= 1024 · 1/2 = 512

Which set of data points represents an exponential function?
Answer:
D
Step-by-step explanation:
In the data set in option D, the x-values are equally spaced, (i.e. [tex] \delta x = 1 [/tex], however, the x-value are not equally spaced. This rules out the possiblity of the data set in option D being a linear function.
To confirm if it's an exponential function, let's examine if the data set has a "constant multiplying factor", n, that takes us from one y-value to a successive y-value.
Thus:
What do we multiply ⅑ with that will give us the next successive y-value, 1?
Thus, let n be the constant multiplying factor we are looking for.
Therefore:
⅑ × n = 1
Solve for n. Multiply both sides by 9
n = 9.
If we multiply the second y-value which is 9, by 9, wwe will get the next successive y-value, which is 81.
This means the data set has a constant multiplying factor of 9.
Therefore, the data set in option D represents an exponential function.
