46 + 1) + y = 5(y - 1) +9 Solve

Radda [10]

Answer:

y=10.75

Step-by-step explanation:

46 + 1) + y = 5(y - 1) +9

47+y=5y-5+9

47+y=5y+4

Collect like terms

47-4=5y-y

43=4y

Divide by 4

43/4=4y/4

43/4=y

y=10.75

The Quadratic Formula 7:Solving Quadratic Equations

Margaret [11]

Answer:

B. 1.14, -0.77

Step-by-step explanation:

As you know the quadratic formula gives you the solution to

ax² + bx + c = 0

as ...

$x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}$

Here, we have a=8, b=-3, c=-7, so the formula tells us the solution is ...

$x=\dfrac{-(-3)\pm\sqrt{(-3)^2-4(8)(-7)}}{2(8)}=\dfrac{3\pm\sqrt{233}}{16}\\\\x\approx \{-0.7665,1.1415\} \qquad\text{matches choice B}$

In the above figure, m∠P = 120° and m∠Q = 5x. If angles P and Q are supplementary angles, what is the value of x and the measure

Lyrx [107]

Answer:

x= 12 and Angle Q measures 60 degrees

Step-by-step explanation:

Supplementary angles are two angles added together to make 180.

So 5x +120= 180 subtract 120 from both sides

5x=60 divide both sides by 5

x= 12

Angle Q= 5 times 12 = 60
