Answer: (-2, 5) and (2, -3)

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

Graph the line y = -2x + 1 (which is in y = mx + b format) by plotting the y-intercept (b = 1) on the y-axis and then using the slope (m = -2) to plot the second point by going down 2 and right 1 unit from the first point:

y - intercept = (0, 1) 2nd point = ( -1, 1).

Graph the parabola y = x² - 2x - 3 by first plotting the vertex and then plotting the y-intercept (or some other point):

$y = x^2-2x-3\quad \rightarrow \quad a=1,\ b=-2,\ c=-3\\\\\text{axis of symmetry:}\ x = \dfrac{-b}{2a}\ \longrightarrow \ x=\dfrac{-(-2)}{2(1)}=\dfrac{2}{2}=1\\\\\text{y-value of vertex:}\ f(1) = (1)^2-2(1)-3\quad \longrightarrow \quad y = 1 - 2 - 3=-4\\\\\text{y-intercept:}\ f(0)= (0)^2-2(0)-3\ \longrightarrow \ y=0 - 0 - 3 = -3 \\$

vertex = (1, -4) 2nd point (y-intercept) = (0, -3)

<em>see attached</em> - the graphs intersect at two points: (-2, 5) and (2, -3)

Problem page two trains leave stations270 miles apart at the same time and travel toward each other. one train travels 70 at mil

Rufina [12.5K]

Let's use the variable n for time (in hours)
70n + 80n = 270
150n = 270
n = 1.8
It will take 1.8 hours, or 1 hour and 48 minutes

Find the area of the triangle

Cerrena [4.2K]

Answer:

Part 1) $P=204\ yd$

Part 2) $A=1,325\ yd^2$

Step-by-step explanation:

Part 1)

we know that

The perimeter of triangle is equal to the sum of its length sides

so

$P=54+97+53=204\ yd$

Part 2)

we know that

The area of triangle is given by the formula

$A=\frac{1}{2}(b)(h)$

we have

$b=53\ yd\\h=50\ yd$

substitute

$A=\frac{1}{2}(53)(50)=1,325\ yd^2$
