The sides are all equal since this is an Equilateral Triangle. So equal both of the equations given 5x - 4 = 3x. Answer is 2

I think the answer is 6 because AB =AC.
5x-4=3x
   +4    +4                       5(2)-4=3(2) 
5x    =  3x+4                       6   = 6    
-3x       -3x
2x   =  4
2/2       4/2
   x =2

Use prime factorization to reduce the fraction 36/180
laila [671]

Answer:

Step-by-step explanation:

36 = 6* 6 = 2* 3 * 2* 3 = 2*2*3*3

180 = 2 * 2 * 3 * 3 * 5 = 2 * 2 * 3*3*5

\frac{36}{180}= \frac{2*2*3*3}{2*2*3*3*5} =  \frac{1}{5}

What is the slope of -y=-x+6
Katarina [22]

<u>Answer:</u>

  • m = 1
  • b = -6

<u>Step-by-step explanation:</u>

We know that:

  • -y = -x + 6
  • y = mx + b

First, we need to change the 'y' sign.

  • => -y = -x + 6
  • => y = x - 6

Now, let's compare both of the equations to find slope.

  • => (y = x - 6) = (y = mx + b)

We can see that the slope is 1 and the y-intercept is -6.

<u>Conclusion:</u>

Therefore:

  • m = 1
  • b = -6

Hoped this helped.

The table shows the number of calories in four meals and the cost of each meal.
Aleksandr-060686 [28]

Answer:

A weak negative correlation

Step-by-step explanation:

correlation, r = \frac{∑(y-\alpha)(x-\beta  }{\sqrt{∑(y-\alpha)^2∑(x-\beta )^2 } }

where,

\alpha = \frac{∑y}{n} \\\beta =\frac{∑x}{n} \\∑ = summation

\alpha = \frac{3230}{4} = 807.5\\\\\\\beta =\frac{46}{4} = 11.5

therefore,\\\\r= -0.12924

This represents a weak negative correlation
