If a line contains the point (0, -1) and has a slope of 2, then which of the following points also lies on the line?(2, 1)
(1, 1)
(0, 1)

Answers

Answer:

(1, 1)

Step-by-step explanation:

Since, the equation of the line with slope m and passes through $(x_1, y_1)$ is,

$y-y_1=m(x-x_1)$

Here,

$x_1=0, y_1 = -1, m = 2$

Thus, the equation of the line,

y + 1 = 2(x-0)

⇒ y + 1 = 2x

If a point lies on the line then it must satisfy the equation of the line,

For (2, 1)

1 + 1 ≠ 2(2)

For (1, 1)

1 + 1 = 2(1)

For (0, 1)

1 + 1 ≠ 2(0)

Thus, the point (1, 1) lies on the line.

the slope is 2/1, So the rise is 2 and the run is 1. So, (1,1) is on the line

Simplify open parentheses x to the 4 fifths power close parentheses to the 3 sevenths power . x to the 7 twelfths power x to the 12 over 35 power x to the 13 over 35 power x to the 43 over 35 power

Answers

Answer:

x to the 12 over 35

Step-by-step explanation:

Given expression,

Open parentheses x to the 4 fifths power close parentheses,

$\implies (x^(4)/(5))^(3)/(7)$

By using the property of exponent $(a^m)^n=a^(mn)$

We get,

$=x^{(4)/(5)* (3)/(7)}$

$=x^(12)/(35)$

= x to the 12 over 35,

Answers

Answer:

For each of the three basic trig functions, (sin, cos, tan) there are three more which act as their reciprocals. (csc, sec, and cot respectively)

Reciprocals, of course, are flipped fractions. If you have some number x, the reciprocal can be expressed as .

An important property of reciprocals is that if you mutliply them together they will cancel out--take for example.

Since secӨ is literally defined as the reciprocal of cosӨ, it is evident that

Which equation shows the quadratic formula used correctly to solve 7x2 = 9 + x for x?

Answers

For future reference, use a * to show the multiplication sign because in math x is a variable. 7*2 = 9 + x

Now multiply 7*2= 14

14 = 9 + x

Now subtract 9 from both sides to isolate the x

5 = x or x= 5

Which statement correctly describes a property of white light?A. It makes all objects appear white.

B. It contains different wavelengths of visible light.

C. It allows light waves to be transmitted.

D. It contains all waves on the electromagnetic spectrum.

Answers

The statement that correctly describes a property of white light is that it b) contains different wavelengths of visible light.
When white light strikes any object that reflects any wavelength of visible light, that object appears to be the color that it reflects.

The correct statement out of the 4 choices for this question is the property of white light contains different wavelengths of visible light.
