The correct answer is D) y = 2x - 5

To find the equation of the line, start by finding the slope. You can do this by using the slope formula below.

m(slope) = (y2 - y1)/(x2 - x1)

m = (1 - -3)/(3 - 1)

m = 4/2

m = 2

Now that we have the slope, we can use it along with either point in point-slope form to get the equation.

y - y1 = m(x - x1)

y - 1 = 2(x - 3)

y - 1 = 2x - 6

y = 2x - 5

in an isosceles triangle, the perimeter is 75 cm and one of the sides is 25 cm. Find all its sides. can you find all angles of t

stepan [7]

Answer:

all angles of the triangles is 60

Step-by-step explanation:

the perimeter = 2*side of an isosceles triangle + bottom edge

----> bottom edge = the perimeter - 2*side of an isosceles triangle =25

----> This is an equilateral triangle ----> all angles of the triangles is 60

The line of reflection is y=

Trava [24]

Answer:

$y = \frac{1}{-1}x + 0$ $or$ $y = \frac{1}{-1}x$

Step-by-step explanation:

$y = mx + c$

$m = \frac{y_{2} -y_{1}}{x_{2} - x_{1} } }$

$(x_{1},y_{1}) = (-1,1)\\(x_{2},y_{2}) = (-2,2)$

$m = \frac{2 - 1}{(-2) - (-1)}$

$m = \frac{2 - 1}{-2 +1 }$

$m = \frac{1}{-1}$

$c = 0$

$y = \frac{1}{-1}x + 0$ $or$ $y = \frac{1}{-1}x$

ASAP AWARDING MAJOR POINTS Determine the symbols(+,-,*. And division) to be placed in each ⭕️ the first one must be simplified t

atroni [7]

To get our answer, can either work backwards, or use another viable strategy, giving random operations until we find the correct answer.

40/10/4*(8/2-3)*5^2 = 25

The second problem is much simpler. There is no exponent in this problem, therefore making it much easier to complete.

(9+5)+2+4+30-2+3 = 51

Hope this helps. :)
