The equation of a line given two points needs to be found. Samuel claims that slope-intercept form will generate the equation and Helena claims that point-slope form will find the equation. Who is correct? Explain your reason by describing both forms.
Please help me with this question.
The answer is:put the equation xa+yb=1 to the slope intercept form and find its slope and y-intercept.
Sample Answer: Both are correct. Using either form will result in the same equation. The slope-intercept form uses slope and a point to find the y-intercept. Point-slope form uses the slope and a point to solve for y to generate the equation.

4x+1= 2x +7
How to solve this equation?
Answer:
3
Step-by-step explanation:
4x +1 =2x +7
4x - 2x =7 - 1
2x =6
x=6 :2
x=3
Answer:
-2x to both sides
-1 to both sides
then you get 2x=6
divide each side by 2

square root of 70 is
rational or iftationet
Answer:
Step-by-step explanation:
It's Irrational.
sqrt(70) = sqrt(2 * 5 * 7)
You can't pull anything out of the right to leave the number under the root sign = to 1. That means that since all three roots are irrational, the whole number is irrational, In fact it takes only 1 number other than 1 left under the root sign to make the result irrational.
√50 = √(5 * 5 * 2)
The 5's will produce one number outside the root sign -- five. That makes the result
5√2 The result is irrational because √2 is irrational

The diameters of cherry tomatoes produced by a large farm have an approximately Normal distribution, with a mean diameter of 22 mm and a standard deviation of 2.5 mm. What proportion of such tomatoes have a diameter between 20 and 26 mm?
Answer:
0.7333
Step-by-step explanation:
2021 Math
Proportion of such tomatoes have a diameter between 20 and 26 mm is 0.7333.
What is standard deviation?It's a way to measure how far each data point is spread from the average value.
let x represents the diameters of cherry tomatoes produced by large farm which is formally distributed with mean = 22m
and, standard deviation= 2.5 mm
Now, proportion of tomatoes have diameter between 20 and 26 mm
=P (20 < x< 26)
=P(20-22 / 2.5 < [tex]x- \mu/ \sigma[/tex] < 26- 22/2.5)
=P(-0.8 < z < 1.6)
=P(z = 1.6) - P(z=-0.8)
=0.9452 - 0.2119
==0.7333
Hence, proportion of such tomatoes have a diameter between 20 and 26 mm is 0.7333.

Given f(x) = 3x- 1 and g(x) = 2x-3, for which value of x does g(x) = f(2)?
Options:
A)x=3/2
B)x=2
C)x=5/2
D)x=4
Answer: x = 4
Step-by-step explanation: f(2) = 3(2)-1 = 5. Meaning x needs to be a value that makes g(x) = 5. You can set them up equal to each other 5 = 2x-3 and solve. You end up getting x = 4.
f(x)=-x2+8x-1 find f(3) show work

The square root of which of the following integers is between 7 and 8 ?
“Identify the CORRECT formula based on the sequence” do not answer on some bs .
Answer:
see explanation
Step-by-step explanation:
there is a common ratio between consecutive terms , that is
21 ÷ 7 = 63 ÷ 21 = 3
this indicates the sequence is geometric with explicit formula
[tex]a_{n}[/tex] = a₁ [tex]r^{n-1}[/tex]
where a₁ is the first term and r the common ration
here a₁ = 7 and r = 3 , then
[tex]a_{n}[/tex] = 7 . [tex]3^{n-1}[/tex] ← explicit formula
the recursive formula allows a term to be found by multiplying the previous term by r , then
[tex]a_{n}[/tex] = 7 . [tex]a_{n-1}[/tex] ← recursive formula
Mike bought an item online for $60 and he was charged a $3 shipping fee. What percent of the sale price was the shipping fee?
Answer:

Step-by-step explanation:
Given the following question:
The item costs 60 dollars
The shipping costs was 3 dollars
What was the percent of 60 is 3?
To find the answer we divide the shipping fee by the cost and then multiply the answer by 100.

Answer:
12a. 45+0.5x+2x+x = 150
12b. the three unknown sides are 30ft, 60ft, and 15ft.
Step-by-step explanation:
12a. the fence is 150ft. so
45+0.5x+2x+x = 150
12.b solve the equation from 12a.
45+0.5x+2x+x = 150
7x/2 = 105
7x = 210
x= 30
0.5(30) = 15ft
2(30)=30ft
x= 30ft
the three unknown sides are 30ft, 60ft, and 15ft.
