Write the ratio for sin a!!!! thanks!! The first person to answer I will mark brainliest!!!

Answer:

1200 is your awnser

Step-by-step explanation:

Answer:

[tex] a = \dfrac{5}{18} [/tex]

[tex]b = -\dfrac{1}{18}[/tex]

Step-by-step explanation:

You need to rationalize the fraction.

[tex] \dfrac{1}{5 + \sqrt{7}} = a + b\sqrt{7} [/tex]

[tex] \dfrac{1}{5 + \sqrt{7}} \times \dfrac{5 - \sqrt{7}}{5 - \sqrt{7}} = a + b\sqrt{7} [/tex]

[tex] \dfrac{5 - \sqrt{7}}{25 - 7} = a + b\sqrt{7} [/tex]

[tex] \dfrac{5 - \sqrt{7}}{18} = a + b\sqrt{7} [/tex]

[tex] \dfrac{5}{18} - \dfrac{1}{18}\sqrt{7} = a + b\sqrt{7} [/tex]

[tex] a = \dfrac{5}{18} [/tex]

[tex]b = -\dfrac{1}{18}[/tex]

Answer:

Step-by-step explanation:

Im going to assume they want x+108.

You have 2 expressions sitting on a line, so when added to each other they must = 180

So add and set up an equality

x+108+x+78=180

Combine like terms

2x+186=180

Solve

2x+186=180

    -180    -180

2x+6=0

-6       -6

2x=-6

________

2

x=-3

Substitute X for -3

-3+108=

105.

Answer:

1170

45x26=1170

[tex]-3x-2(5x-7)=-12\\-3x-10x+14=-12\\-13x=-26\\x=2\\\\y=5(2)-7\\y=10-7\\y=3[/tex]

Answer:

[tex](x, y) = (-\frac{29}{2}, -12)[/tex]

Step-by-step explanation:

[tex]-12 = 5 x ( -\frac{29}{2} ) - 7 - 3 x ( -\frac{29}{2} ) - 2 x (-12) = -12[/tex]

Answer:

4/3

Step-by-step explanation:

Answer:

x= 4

Step-by-step explanation:

-4x-2 /3=(-6)

-4x-2= 3 (-6)

-4x-2=-18

-4x=-18+2

-4x=-16

x=-16/-4 = 16/4 = 4

Answer:

Step-by-step explanation:

Hi! I'm lazy but I'll explain number two so you get the concept. 2x + y =10

Well, It says x = 5. When a number is next to another number like this: 5(6), it means multiplication. Same when a number and a letter are together like this: 2x. So that means it's 2 times 5, since 5 = x. 2 times 5 is 10. So what plus 10 equals 10 (10 + y = 10) The answer now is obviously 0.  So that's how you do those equations! Hope u understand lol :>

Answer: C) [-1,-3,-7,-19]

Step-by-step explanation:

Range = {-2(-2) - 5, -2(-1) - 5, -2(1) - 5, -2(2) - 5} = {4 - 5, 2 - 5, -2 - 5, -4 - 5} = (-1, -3, -7, -9}

Answer:

-2(-2)-5= -1      -2(-1)-5=-3   -2(1)-5=-7     -2(2)-5=-9... A. {-1, -3, 7, 9}

Step-by-step explanation:

By substituting each value of the domain of x in the function and solving it we will get the range of the function for respective domain

The given function is :

f(x) = -2x - 5

For x = -2 , f(x) is:

f(-2) = (-2*-2) - 5 = 4 - 5 = -1

For x = -1, f(x) is :

f(-1) = (-2*-1) - 5 = 2 - 5 = -3

For x = 1 , f(x) is

f(1) = (-2*1) - 5 = -2 -5 = -7

For x = 2, f(x) is

f(2) = (-2*2) - 5 = -4 -5 = -9

The range is -1 , -3 , -7 , -9

Hope this helps ..!!

Thank you :)

Answer:

0, 5.5

Step-by-step explanation:

when they ask for a y-intercept, x is always zero, so now we eliminate two of the answers, and we will only have (0, 1) or (0, 5.5). At the beginning of the question it said a plant is currently at 5.5, so it started as 5.5 (0, 5.5)

so THE ANSWER IS  (0, 5.5)

Answer: its D

Step-by-step explanation:

Answer:  D♪ヽ(･ˇ∀ˇ･ゞ)

Step-by-step explanation:

First put it in decreasing power according to x.

x^4-5x+8+x^2

=x^4+x^2-5x+8

Now this question is asking what is the highest degree of x you see in this function.

4 of course.

Therefore the answer to his question is degree of 4.

Done!

Answer:

  b, d

Step-by-step explanation:

When you're taking the cube root, the thing you're taking the cube root of is best expressed as a cube.

You know that 2^3 = 8 and 3^3 = 27, so any other representation of 8 or 27 is irrelevant to the problem.

The appropriate choices are the second and fourth ones (B, and D).
