What are the solutions of the quadratic equation (x+3)^2=49?

rosijanka [135]

Answer:

d. x = 4 and x = –10

Step-by-step explanation:

(x+3)^2=49

Take the square root of each side

sqrt((x+3)^2)=±sqrt(49)

x+3 = ±7

Separate into 2 equations

x+3 = 7 x+3 = -7

Subtract 3 from each side

x+3-3=7-3 x+3-3 = -7-3

x =4 x =-10

Need help on my math homework

scoray [572]

200 +6m = 500-6m

add 6m to each side

200+12m = 500

subtract 200 from each side

12m = 300

divide both sides by 12

m = 300/12 = 25

25 minutes

check:

200+ 25*6 = 200 +150 = 350

500 - 25*6 = 500-150 = 350

troy's truck has a 30 gallon gas tank and gets an average of 21 miles per gallon.write an equation to represent the amount of ga

GuDViN [60]

Let

x---------> represent the number of miles Troy's has driven

y--------> represent the amount of gas in Troy's truck

we know that

the equation that represents the amount of gas, y, in troy' s truck after driving a certain number of miles, x is

$y-y1=m*(x-x1)$

where

m is the slope---------> $\frac{gallon}{miles}$

in this problem the slope is equal to $-\frac{1}{21} \frac{gallons}{miles}$

it's negative because the tank is going to be consumed

assuming he starts with a full tank

$for\ x=0\ y=30\ gal$

substitute in the formula above

$y-y1=m*(x-x1)\\\\ y-30=-\frac{1}{21}*(x-0)\\\\ y=-\frac{x}{21}+30$

therefore

the answer is

the equation $y=-\frac{x}{21}+30$
