Answer: (0, -7.2)

Step-by-step explanation:

Substituting into point-slope form, the equation is

y+6=4(x-0.3)

The y-intercept is when x=0, so substituting in x=0,

y+6=4(-0.3)\\\\y+6=-1.2\\\\y=-7.2

So, the y-intercept is (0, -7.2).

how can an expression written in either radical form or rational exponent form be rewritten to equivalent forms?
miss Akunina [59]
You can rewrite radical form expressions by putting the expression to the power of 1/n, n depending on the radical. For example: sqrt2 = 2^(1/2) or cuberoot4= 4^(1/3). Vice versa with rational exponent equations: 5^(1/2) = sqrt5 or 3^4/3 = cuberoot3^4

Find the value of the variable.<br> All answers
svp [43]

First one.

Since the two angles are congruent through vertical angles theorem,

5x = 6x - 8

5x - 6x = -8

-x = -8

x = 8

Second one.

Use the 180° rule.

(8x - 2) + (2x + 2) = 180

8x - 2 + 2x + 2 = 180

8x + 2x + 2 - 2 = 180

10x = 180

x = 180 / 10

x = 18

Third one.

Vertical angle theorem.

7x = 5x + 40

7x - 5x = 40

2x = 40

x = 40 / 2

x = 20

If tan of theta =3/4 what is sec of theta​
zhannawk [14.2K]

Answer:

<u>5/4</u>

Step-by-step explanation:

Given :

  • tanθ = 3/4 = opposite/adjacent

Finding the missing side :

  • The hypotenuse must be found
  • √3² + 4²
  • √25
  • 5

Taking the sec ratio :

  • secθ = hypotenuse/opposite
  • secθ = <u>5/4</u>

If the line joining (3x, x+1) and (11,12) has a slope of 4 what is the value of x​
Irina18 [472]

Answer:

x = 3

Step-by-step explanation:

(3x,\: x +1)=(x_1, \:y_1)

(11,\: 12)=(x_2, \:y_2)

slope =  \frac{y_2 - y_1}{x_2 - x_1} \\  \\ 4 =  \frac{12 - (x + 1)}{11 - 3x}   \\  \\ 4 =  \frac{12 - x  -  1}{11 - 3x}   \\  \\ 4 =  \frac{11 - x}{11 - 3x}   \\  \\ 4(11 - 3x) = 11 - x \\  \\ 44 - 12x = 11 - x \\  \\ 44 - 11 = 12x - x \\  \\ 33 = 11x \\  \\ x =  \frac{33}{11}  \\  \\  \huge \red{ \boxed{x = 3}}
