The y-intercept of the line whose equation is x - y = -1 is -1 0 1

2 answers:

7 0

The y-intercept in the equation in the form y = mx + b is b.
To find the y-intercept in x - y = -1, isolate y on the left-hand side:

x - y = -1
-y = -x - 1
y = x + 1

b in this equation is 1, so the y-intercept is 1.

Hope this helps.

Absorption rates into the body are important considerations when manufacturing a generic version of a brand-name drug. A pharmac

Darya [45]

Answer:

Correct option: (D).

Step-by-step explanation:

A null hypothesis is a hypothesis of no difference. It is symbolized by H₀.

A Type I error is the probability of rejection of the null hypothesis of a test when indeed the the null hypothesis is true.

The type I error is also known as the significance level of the test.

It is symbolized by P (type I error) = α.

In this case the researcher wants to determine whether the absorption rate into the body of a new generic drug (G) is the same as its brand-name counterpart (B) or not.

The hypothesis for this test can be defined as:

H₀: The absorption rate into the body of a new generic drug and its brand-name counterpart is same.

Hₐ: The absorption rate into the body of a new generic drug and its brand-name counterpart is not same.

The type I error will be committed when the null hypothesis is rejected when in fact it is true.

That is, a type I error will be made when the the results conclude that the absorption rate into the body for both the drugs is not same, when in fact the absorption rate is same for both.

Thus, the correct option is (D).

Solve by elimination 3x+2y=19 -9x+8y=-29

Alja [10]

Step-by-step explanation:

(3x + 2y =19)(3)

-9x + 8y =-29

9x + 6y = 57 NOTE: we cross here 9x in first

-9x + 8y = -29 we cross here - 9x in second

Since 9x and - 9x are opposite

___________

6y +8y = 57 - 29

14y = 28

Y=28/14

Y=2

Replace y in second equation of this system:

-9x + 8y = - 29

-9x +8(2)= - 29

-9x + 16 = - 29

-9x = -29 - 16

-9x = - 45

X= -45/-9

X=5

Hope this helps..

Solve the equation and this is an assignment btw

lilavasa [31]

Answer:

z=6 and z=-6

Step-by-step explanation:

$7z^2=252$

Divide both sides by 7

$\frac{7z^2}{7} =\frac{252}{7} \\z^2=36$

Find the square root

z=±√36

z=±6

Therefore, z=6 and z=-6.

I hope this helps!
