Answer:
y=-3/4x-2
Step-by-step explanation:
y-y1=m(x-x1)
y-1=-3/4(x-(-4))
y-1=-3/4(x+4)
y=-3/4x-12/4+1
y=-3/4x-3+1
y=-3/4x-2
What is the solution of the system of equations
y =2x - 3
Answer:
-37/5= y
x=11/5
Step-by-step explanation:
4x-3y=31
-3y=-4x+31 regroup it to match the other
-2 y=(2x-3)(-2) multiply by -2 to get -4x
-3y=-4x+31
-2y=-4x+6 adding
-5y=37 divide
-37/5= y
4x-3(-37/5)=31
x=11/5

Please help me, I will give the best answer brainliest. I have a deadline finish of today, and I really want to get my work done... The following figures show the first two steps of a proof of the pythagorean theorem, which of the following statements about this proof is false? Thank you if you can help :)
Answer:
so since there isn't any pics to work with, here we go.
the pytha theorem states that a^2 + b^2 = c^2, you've probably seen/heard this all the time but really know what it means.
It means the the shorter side of the triangle (the ones that aren't the hypotenuse) multiplied by themselves, and then added together equals the hypotenuse also multiplied by itself.
So if i have a triangle with sides lengths of 3 and 4, and I want to calculate the hypotenuse length, the equation would be 3^2 + 4^2 = x^2
we then get 9 + 16 = x^2 –––––> 25 = x^2 ––––> √25 = x
so the hypotenuse equals 5.
hope this helps.

Answer: 2,250 meters
Step-by-step explanation:
New York City and Boston are 225 miles apart.
New York City and Salt Lak are 10 times the distance of New York and Boston.
This means that New York City and Salt Lake are 10 times 225 miles apart:
= 225 * 10

Sebastian grew 21-3 inches each year for the past 3 years. How many inches total has Sebastian grown in the past 3 years?
Answer:
the Answer is 21.3 x 3
Step-by-step explanation:
inches that grew each year for the past 3 years - 21.3
SO here 1 year = 21.3 inches
and it is asked about 3 years so we have to multiply 21.3 inches x 3 times ( 3 years).

What is the value of x in the equation 4 x plus 8 y equals 40, when y equals 0.8?
Answer:
now first of all we should plug in 0.8 to y .
now we have this simple equation: 4x+8.(0.8)=40
4x+6.4=40
4x=33.6
x=8.4 (hope it helps :) )
Step-by-step explanation:
Answer:
[tex]4x + 8y = 40 \\ 4x + 6.4 = 40 \\ 4x = 40 - 6.4 \\ 4x = 33.6 \\ x = 8.4[/tex]

You manage a warehouse and need to replace a forklift.
Alocal retailer sells the model you want for $1,299 plus a
6% sales tax. A store located just over the state line sells
the same model for $1,359 plus a 4% sales tax.
Answer:
If youre trying to see which is cheaper, the local forklift would cost $1376.94 after tax. The other forklift would cost $1413.36.
Step-by-step explanation: Hope that helped
The cost after the sale will be $1376.94 and $1413.36.
What is the percentage?The quantity of anything is stated as though it were a fraction of a hundred. A quarter of 100 can be used to express the ratio. Per 100 is what the term percent signifies. The symbol ‘%’ is used to symbolize it.

Step-by-step explanation:
Answer:
C
Step-by-step explanation:
It is C because if you multiply each number on the left by 250 and then add 500, you will get the number on the right.
4 x 250 = 1000 + 500 = 1500
8 x 250 = 2000 + 500 = 2500
10 x 250 = 2500 + 500 = 3000
13 x 250 = 3250 + 500 = 3750

A) X = 5, y = 15
B) x = 15, y = 5
C) x = 30, y = 60
D) x = 60, y = 30
Answer:
A) X = 5, y = 15
Step-by-step explanation:
De la figura:
∠EHD = ∠EGB (los ángulos correspondientes son iguales). Por lo tanto;
18x-2y = 60 (1)
Además, ∠CHF = ∠EHD (los ángulos opuestos serticales son iguales). Por eso;
18x-2y = 9x + y
18x-9x-2y-y = 0
9x-3y = 0 (2)
Para resolver x e y, resolvemos la ecuación (1) y (2) simultáneamente.
Multiplique la ecuación (2) por 2 y reste de la ecuación (1):
4 años = 60
y = 15
Pon y = 15 en la ecuación (2):
9x-3 (15) = 0
9x-45 = 0
9x = 45
x = 5

Answer: Option 'D' is correct.
Explanation:
We are required to find that length of sides which cannot be sides of triangle,
As we know that " Sum of two sides is always greater than the third side "
If any option does not follow the above postulate that will be our required answer :
D) 21 m, 6 m, 10 m
So, 21 m, 6 m, 10 m cannot be the length of any triangle as it does not satisfy the above mentioned postulate .
In the past, 35% of the students at ABC University were in the Business College, 35% of the students were in the Liberal Arts College, and 30% of the students were in the Education College. To see whether or not the proportions have changed, a sample of 300 students was taken. Ninety of the sample students are in the Business College, 120 are in the Liberal Arts College, and 90 are in the Education College. The calculated value for the test statistic equals
Answer:
The test statistic for Business College is -0.9944
The test statistic for Liberal Arts College is 1.1483
The test statistic for Education College is 0
Step-by-step explanation:
The percentage of ABC University college students in
Business College = 35%
Liberal Arts College = 35%
Education College = 30%
The number of students in the sample = 300 students
In the sample, the number of students in;
Business College = 90
Liberal Arts College = 120
Education College = 90
Therefore;
The percentage of Business College students = 90/300 × 100 = 30%
The percentage of Liberal Arts College, = 120/300 × 100 = 40%
The percentage of Education College, [tex]\hat p[/tex] = 90/300 × 100 = 30%
The test statistic for the difference in two proportions is given as follows;
[tex]z=\dfrac{\hat{p}-p}{\sqrt{\dfrac{p \cdot q}{n}}}[/tex]
Where;
[tex]\hat p[/tex] = The sample proportion
p = The population proportion
q = 1 - p
n = The sample size
The test statistic for Business College is;
[tex]z=\dfrac{0.3-0.35}{\sqrt{\dfrac{0.35 \times 0.65}{90}}} \approx -0.9944[/tex]
The test statistic for Liberal Arts College is;
[tex]z=\dfrac{0.4-0.35}{\sqrt{\dfrac{0.35 \times 0.65}{120}}} \approx 1.1483[/tex]
The test statistic for Education College is;
[tex]z=\dfrac{0.3-0.3}{\sqrt{\dfrac{0.3 \times 0.70}{120}}} \approx 0[/tex]
Answer:
Using the Chi-Square test we find test statistic equals 4.29
Step-by-step explanation:
Start by calculating the expected value:
35% Business College = 0.35 x 300 = 105
35% Liberal Arts College = 0.35 x 300 = 105
30% Education College = 0.3 x 300 = 90

For which value of x is the row in the table of values the incorrect? The function is quadric function y=5x^2
A. x=5
B. x=0
C. x=3
D. x=2
Answer:
x = 2
Step-by-step explanation:
Substitute x = 2 into y = 5x² , that is
y = 5(2)² = 5(4) = 20 ≠ 10
Thus (x, y ) = (2, 20 ) and not (2, 10 )
