Subtract 3/4x from both sides

1/3x-4-3/4x= 3/4x+1-3/4x

-5/12x-4=1

Add 4 to both sides

-5/12x-4+4=1+4

-5/12x=5

Multiply both sides by 12/(-5)

(12/-5)*(-5/12x)= (12/-5)*(5)

x= 12

I hope that's help.

Answer:

Step-by-step explanation:

If ΔABC ~ ΔPQR

$\frac{PQ}{AB} =\frac{QR}{BC} = \frac{RP}{CA}$

$\frac{AB}{PQ} =\frac{BC}{QR} =\frac{CA}{RP}$

Write an equation of the line that passes through (1, −1) and is perpendicular to the line y=1/2x−3. An equation of the perpendi

lapo4ka [179]

Y = 1/2x - 3. Slope here is 1/2. A perpendicular line will have a negative reciprocal slope. All that means is flip the slope and change the sign. So the perpendicular line will have a slope of -2.

y = mx + b
slope(m) = -2
(1,-1)...x = 1 and y = -1
now we sub and find b, the y int
-1 = -2(1) + b
-1 = -2 + b
-1 + 2 = b
1 = b

so ur perpendicular equation is : y = -2x + 1

WILL GIVE BRAINLIEST Mr. and Mrs. Bailey hope to send their son to college in eleven years. How much money should they invest no

Ronch [10]

Mr. and Mrs. Bailey need to invest $2906.50 so as to send their son to college.

<h3>Compound interest</h3>

Compound interest is given by:

$A=P(1+\frac{r}{n})^{nt}$

where A is the amount after t years, P is initial amount, r is the rate and n is the times compounded per period

Given that n = 1, r = 9% = 0.09, A = $7500 t = 11. Hence:

$7500=P(1+\frac{0.09}{1} )^{1*11}\\\\P=\$2906.50$

Mr. and Mrs. Bailey need to invest $2906.50 so as to send their son to college.

The dDifference in hours between full times and the part timers to work three hours a day is 2 working hours how many hours per

hram777 [196]

full timers work 5 hours a day whereas Part timers work 3 hours a day!

<u>Step-by-step explanation:</u>

Here we have , The difference in hours between full times and the part timers to work three hours a day is 2 working hours . We need to find that how many hours per day to full timers work . Let's find out:

Let full timers work x hours , Part time workers work 3 hours a day , According to question, difference in hours between full times and the part timers to work three hours a day is 2 working hours i.e.

⇒ $x-3 = 2$

Adding 3 to make x term alone :

⇒ $x-3+3 = 2+3$

⇒ $x=5$

Therefore, full timers work 5 hours a day whereas Part timers work 3 hours a day!

A ball is thrown vertically upward. After t seconds, its height h (in feet) is given by the function h(t) = 52t - 16t^2 . What i

ahrayia [7]

Answer:

42.25 feet

Step-by-step explanation:

The height function is a parabola. The maximum value of a negative parabola is at the vertex, which can be found with:

x = -b/2a

where a and b are the coefficients in y = ax² + bx + c.

Here, we have y = -16t² + 52t. So a = -16 and b = 52. The vertex is at:

t = -52 / (2×-16)

t = 13/8

Evaluating the function:

h(13/8) = -16(13/8)² + 52(13/8)

h(13/8) = -169/4 + 169/2

h(13/8) = 169/4

h(13/8) = 42.25
