Answer:

See below.

Step-by-step explanation:

7x^2 = 343 Divide both sides by 7

7x^2/7 = 343/7

x^2 = 49 Take the square root of both sides.

sqrt(x^2) = sqrt(49)

x = +/- 7

Answers

7
- 7
sqrt(49)
- sqrt(49)

I think the last two are kind of iffy. I'm not sure you can call them solutions, but the question probably assumes they are. If you use all four answers and get it wrong, them submit +7 and - 7.

What is the equation of the line that passes through the point (4,7) and has a slope of o?

Svetlanka [38]

Answer:

The equation of the line that passes through the point (4,7) and has a slope of 0 will be:

$y=7$

Step-by-step explanation:

As we know the equation of a line in a slope-intercept form of an equation is

$y = mx + b$

Here,

m is the slop

b is the y-intercept

substituting the point (4,7) and slope m=0

$y = mx + b$

$7=0(4)+b$

$7=0+b$

$b=7$

Therefore, the equation of the line that passes through the point (4,7) and has a slope of 0 will be:

$y = mx + b$

$y=0x+7$

$y=7$

The square of a number x is 92. The number x is between what two consecutive whole numbers?

natta225 [31]

The number X is placed somewhere between 9 and 10. That's because 9 squared is 81 and 10 squared is 100.

Find the x value of x. If necessary round to the nearest tenth. A=49sq.in.

grigory [225]

Answer:

$9.9 ~in$ ✔︎

Step-by-step explanation:

$A=1/2 ~ base * height$

$49=1/2(x)(c)$

$98=x^2$

$x=\sqrt{98}$

$x=7\sqrt{2}$

$x=9.9$
