What is the slope of a line that is parallel to the given line

Mathematics
1 answer:
emmainna [20.7K]2 years ago
3 0

Answer:

-3/2

Step-by-step explanation:

The slope of a line is calculated by finding the rise over run of two points on the line. In this case, I use the points (-3, 4) and (1, -2). Then, I use the formula of \frac{y_{2} - y_{1}}{x_{2}- x_{1} }  to find the slope. If 4 is y_{2}, -3 is x_{2}, 1 is x_{1} and -2 is y_{1}, then,

\frac{4 - (-2)}{ -3- 1 } = \frac{6}{-4} = \frac{3}{-2}

Furthermore, the slope of a parallel line is always the same as the given line. Therefore, the answer is -3/2.

The value of a house has increased by 5% the house is now valued at £609000 what is the value of the house before the increase?
lutik1710 [3]

Answer:

Current \ price = 609000\\\\Let \ the \ original \ price \ be = x\\\\\% increase = 5 \% \ of \ x = \frac{5}{100} \times x = \frac{5x}{100}\\\\Price \ after \ increase, current\ price = \frac{5x}{100} + x\\\\

=> 609000 = \frac{5x}{100} + x\\\\=>609000 = \frac{105x}{100}\\\\=> x = \frac{609000 \times 100}{105}\\\\x = 580000

Therefore original price = $580,000

A large city in the ancient world was square-shaped. measured in miles, its area numerically exceeded its perimeter by about 132
melisa1 [442]
Area = perimeter + 132.  

Let  each side of the city be x miles long, then:-

x^2 = 4x  + 132
x^2 - 4x - 132 = 0

x  =  [-(-4) +/- sqrt((-4)^2 - 4 * 1 *-132)] / 2

x = 13.66, -9.66   We ignore the negative

So the city  has dimension of 13.66 * 13.66

13.7 * 13.7   to nearest 10th
