Larry gets $7 for each of the 3 flower beds he weeds and Y dollars to edge a yard. Zach will get $25 to clean a garage and Y dol
lbvjy [14]

Answer:

Expression for Larry will be;

\$21 + \$Y\geq \$X

Expression for Zach will be;

\$25 + \$Y\geq \$X

Step-by-step explanation:

Given:

Larry gets $7 for each of the 3 flower beds he weeds and Y dollars to edge a yard.

Amount for each flower bed he weeds = $7

Number of flower bed he weeds = 3

Total amount he gets for 3 flower bed he weeds = \$7\times 3 =\$21

Amount earn to edge a yard = Y

Total amount Larry will earn = $21 + $Y

Now Zach will get $25 to clean a garage and Y dollars to wash a car.

Amount earned to clean garage = $25

Amount earned to wash as car = $Y

Total Amount Zach will earn = $25 + $Y

The Both have to make X dollars to meet their goals.

Expression for Larry will be;

\$21 + \$Y\geq \$X

Expression for Zach will be;

\$25 + \$Y\geq \$X

Solve the following equation for x: 6x-16=14
Ivenika [448]

To solve the equation for x, first, we add 16 from both sides of the equation:

\begin{gathered} 6x-16+16=14+16, \\ 6x=30. \end{gathered}

Now, we divide by 6:

\frac{6x}{6}=\frac{30}{6}.

Finally, we get that:

x=5.

Answer:

x=5.

For questions 3 – 5, an airplane is heading south at an airspeed of 540 km/hr, but there is a wind blowing from the northeast at
GuDViN [60]

First, let's calculate the horizontal and vertical components of the wind speed (W) and the airplane speed (A), knowing that south is a bearing of 270° and northeast is a bearing of 45°:

\begin{gathered} W_x=W\cos45°\\ \\ W_x=50\cdot0.707\\ \\ W_x=35.35\\ \\ \\ \\ W_y=W\sin45°\\ \\ W_y=50\cdot0.707\\ \\ W_y=35.35 \end{gathered}\begin{gathered} A_x=A\cos270°\\ \\ A_x=540\cdot0\\ \\ A_x=0\\ \\ \\ \\ A_y=A\sin270°\\ \\ A_y=540\cdot(-1)\\ \\ A_y=-540 \end{gathered}

Now, let's add the components of the same direction:

\begin{gathered} V_x=W_x+A_x=35.35+0=35.35\\ \\ V_y=W_y+A_y=35.35-540=-504.65 \end{gathered}

To find the resultant bearing (theta), we can use the formula below:

\begin{gathered} \theta=\tan^{-1}(\frac{V_y}{V_x})\\ \\ \theta=\tan^{-1}(\frac{-504.65}{35.35})\\ \\ \theta=-86° \end{gathered}

The angle -86° is equivalent to -86 + 360 = 274°.

Therefore the correct option is b.

Without solving determine the number of real solutions for each quadratic equation
seropon [69]

Answer:

b^2-4b+3=0

b²-3x-b+3=0

b(b-3)-1(b-3)=0

(b-3)(b-1)=0

either

b=3 or b=1

.

2n^2 + 7 = -4n + 5

2n²+4n+7-5=0

2n²+4n+2=0

2(n²+2n+1)=0

(n+1)²=0/2

:.n=-1

.

x - 3x^2 = 5+ 2x - x^2

0=5+ 2x - x^2-x +3x^2

0=5+x+2x²

2x²+x+5=0

comparing above equation with ax²+bx +c we get

a=2

b=1

c=5

x={-b±√(b²-4ac)}/2a ={-1±√(1²-4×2×5)}/2×1

={-1±√-39}/2
