The correct answer is C. The slope (rate of change) for this table is given by the equation (14-7)/(2-1) which comes out to be 7/1 or 7 meaning that every time x increases by 1, y increases by 7. In other words, Elise earns $7 for each child she baby sits. So 7 children times $7 per child gives you $49.

Answer:

  3) y = √10

  4) x = 5√2

Step-by-step explanation:

The side ratios of an isosceles right triangle (one of the "special" right triangles) are ...

  1 : 1 : √2

So, for some multiplier k, they can be made to match the sides in your triangles.

__

3) 1·k : 1·k : k√2 = √5 : √5 : y

Clearly, k = √5, so ...

  y = (√5)(√2)

  y = √10

__

4) k : k : k√2 = x : x : 10

  k = 10/√2 = (5√2)/2

  k = x = (5√2)/2

I will give brainlist please someone help!!!​

Answer:

x = 6

Step-by-step explanation:

Alternate angles are congruent.

7x - 9 = 3x + 15               {Subtract 3x form both sides}

7x - 3x -9 = 15

      4x - 9=15            {Add 9 to both sides}

           4x = 15+9

           4x = 24

           x = 24/4

x = 6

Explain please, I’ve been having trouble with this question
GuDViN [60]

Step-by-step explanation:

I didn't need the other angles, but right of the bat you can tell it's two right triangles back to back.

<em>y </em> has to be 90° , as you have noticed they already gave you 70° on the right side of the shape meaning if you were to add 90 which is why plus 70 what would that give you? 160.

the total interior for a triangles angles has to be 180°. if you do the math 180 - 160 you get the leftover 20° for x.

I suck at explaining stuff, hope this helps

Solve for t<br> (88sin20) t-16t^2=0
vivado [14]
(88sin20)(t - 16t²) = 0
(8(0.3090169944)(t - 16t²) = 0
(2.472135955)(t - 16t²) = 0
2.472135955t - 39.55417528t² = 0
