X=5 is the answer because
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)
Answer:
y=2x-8
Step-by-step explanation:
<em>Slope-Intercept Form </em>
<em>y=mx+b where y and x are variables, m is the slope, and b is the y-intercept</em>
<u>1. Find slope using the slope formula </u>
You now have
y=2x+b
<u>2. Plug in one of the given points into the equation and solve for b</u>
y=2x+b
2=2(5)+b
2=10+b
-8=b
<u>Final Answer:</u>
y=2x-8
X+x^2=2
x^2+x-2=0
(x+2)(x-1)=0
So x=-2, 1
