Mathematics
1 answer:
kumpel [21]3 years ago
4 0

Answer:

x= -10

Step-by-step explanation:

So because the angle 55 is part of the same line as one of the unknown angles you can do 180-55 to find that first angle at the top, which is 125.

Next add all three angles (125 + x + 35 + x + 40)=180

Combine the x values to get 2x and subtract the three values from 180

Then 2x= -20, x should be equal to -10

You can plug x back into the values and check your work by adding all the values again, making it all equal to 180 degrees again

16 What value could you put in place of the x to make it a function? * (8, 7) (7,-6) (-4,5) (x, 9)
Tresset [83]

Answer:

(c) 9

Step-by-step explanation:

You can't have a repeated x-value in a function.

8 is taken by (8, 7)

7 is taken by (7,-6)

-4 is taken by (-4, 5)

9 is the only number that is not taken by any other point yet.

Remember that for a relationship to be a function it can't have repeated x-values. However, it doesn't matter to have the same x and y values!

Hope this helped!

Olin [163]
To determine the distance between two points, we use the equation,
                                   distance = √(x₂ - x₁)² + (y₂ - y₁)²
Substituting the known values for the abscissa and ordinates of the points,
                                distance = √(0 - 2)² + (0 - 5)² = √29 ≈ 5.39 
Therefore, the distance between these two points is approximately equal to 5.39.

Evaluate the expression when g=3 and h= 17 <br> h−5g
Aleks04 [339]
2.
EXPLANATION:
If g= 3 we can replace g with 3.

Now we have h-5 x 3

and if h= 17, we can replace h with 17.

Now we have 17 - 5 x 3.

because of pemdas, multiplication is first

5 x 3 is 15,

17 - 15 is 2.
