2x+y=8;y i have no idea what theyre asking. Its solve each equation for the indicated variable

1 answer:

8 0

If solving for y:

→ 2x + y = 8
→ Take away 2x from both sides
→ y = 8 - 2x

If solving for x:

→ 2x + y = 8
→ Take away y from both sides
→ 2x = 8 - y
→ Divide both sides by 2
→ x = $\frac{8-y}{2}$

The circle below has center O, and its radius is 4 ft. Given that m ZAOB=50°find the length of the minor arc AB.

exis [7]

Answer:

The length of minor arc AB is $\frac{10}{9}$ π ft

Step-by-step explanation:

The formula of the length of an arc in a circle is L = $\frac{\alpha }{360}$ × 2πr, where α is the central angle subtended by the arc, and r is the radius of the circle

∵ The radius of the circle is 4 ft

∴ r = 4

∵ ∠AOB is a central angle subtended by minor arc AB

∵ m∠AOB = 50°

∴ α = 50°

Substitute the values of r and α in the rule above

∵ L = $\frac{50}{360}$ × 2π(4)

∴ L = $\frac{10}{9}$ π

∴ The length of minor arc AB is $\frac{10}{9}$ π ft

Brums [2.3K]

Answer:

$x_{1} =-14\\\\x_{2} =6$

Step-by-step explanation:

$x^{2} +8x-84=0\\\\x=\dfrac{-b \pm \sqrt{b^{2}-4ac } }{2a} \\\\a=1; \: \: b=8; \: \: c=-84\\\\x=\dfrac{-8 \pm \sqrt{8^{2}-4 \cdot 1 \cdot (-84) } }{2 \cdot 1}=\dfrac{-8 \pm \sqrt{400 } }{2}=\dfrac{-8 \pm20}{2} =-4 \pm 10\\\\x_{1} =-14\\\\x_{2} =6$
