A^2 + b^2 = c^2
8^2 + b^2 = 11^2
64 + b^2 = 121
b^2 = 121 - 64
b^2 = 57
b = sqrt 57
b = 7.54 rounds to 7.5 ft <==
Answer:
Equation: y = 2x — 3
Slope: 2
Y-intercept: —3
Step-by-step explanation:
m=∆y/∆x
= —3—(—1)/0—1
= —2/—1
= 2
We Know: y - y0 = m (x—x0)
y — (—3) = 2 (x — 0)
y + 3 = 2x
y = 2x — 3
So
Equation: <em>y </em><em>=</em><em> </em><em>2</em><em>x</em><em> </em><em>—</em><em> </em><em>3</em>
Slope: <em>2</em>
Y-intercept: —3
The value of the x is 120
It belongs in rational numbers because if you converted it into a decimal, it would only be .25. If it was a number like pi, then it would be an irrational number because there is almost no end to it.
Answer:
EY = 5.3 cm
Step-by-step explanation:
∵ Δ ABC similar to ΔDEF
∴ AB/DE = BX/Ey
∵ AB = 12 cm
∵ DE = 8 cm
∵ BX = 8 cm
∴ 12/8 = 8/EY
∴ 12EY = 8 × 8 ⇒ 12AY = 64
∴ EY = 64 ÷ 12 = 5.3333 ≅ 5.3 cm
