Answer: 6. x=29yd 7. x-6.5cm
Step-by-step explanation:
6. All the sides of the square are equal (we know this because of the little lines on the sides), and the equation for finding the hypotanuse of a triangle is a^2+b^2=c^2. That's 20^2+21^2=x^2. That simplifies to 841^2=x^2, which then simplifies to x=29.
7. The bottom of the triangles are the same length, so each one is 2.5cm long. The angles are also the same, which means that the triangles are equal, so we have 2 similarities between the triangles, so they are both the same (You'll learn why later in math)
The table indicates a y-value of 115 when x = 0. That corresponds to the y-intercpt of the equation.
The table values increase by 64 for each increase of 2 in x-value. That corresponds to the slope (32) of the equation.
Yes, the equation and the table represent the same function.
