taurus [48]3 years ago
3 0

Answer:

y = 2x + 3

Step-by-step explanation:

We can find the slope.

\frac{ 5 + 1}{1 + 2 }  =  2

so m is 2

y = 2x + c

Plug one the equations in to find c.

- 1 = 2( - 2) + c

- 1 =  - 4 + c

3 = c

so the equation is

y = 2x + 3

Y/a −b= y/b −a, if a≠b<br><br> solve for y
Kamila [148]

Answer:

y= ab    if a≠b

Step-by-step explanation:

y/a −b= y/b −a

multiply each side by ab to clear the fractions

ab(y/a −b) = ab( y/b −a)

distribute

ab * y/a - ab*b = ab * y/b - ab *a

b*y - ab^2 = ay -a^2 b

subtract ay on each side

by -ay -ab^2 = ay-ay -a^2b

by -ay -ab^2 =-a^2b

add ab^2 to each side

by-ay -ab^2 +ab^2 = ab^2 - a^2b

by-ay = ab^2 - a^2b

factor out the y on the left, factor out an ab on the right

y (b-a) = ab(b-a)

divide by (b-a)

y (b-a) /(b-a)= ab(b-a)/(b-a)    b-a ≠0   or b≠a

y = ab

evablogger [386]

Answer:

H1 : μ < 1225

Step-by-step explanation:

The alternative hypothesis in carrying out a statistical test could be explained as a notion which aims to displace or rival an initial position, the null hypothesis.

When declaring an hypothesis, the statement compares the initial or population mean in the hypothesis statement and not the result or outcome of the sample statistic.

In the scenario above :

The null is of the notion that :

H0 : μ = 1225 ;

Hence, the stance of the alternative which is that the mean is lower or less will be written as :

H1 : μ < 1225
