Answer:

x = 5.5

Step-by-step explanation:

Solve for x by simplifying both sides of the equation, then isolating the variable.

$-\frac{1}{2} +2=-x+7$

$-\frac{1}{2} +2= 1.5$

$1.5=-x+7$

-7 -7

$-5.5 = -x$

Divide both sides by -1.

$5.5 = x$

Write the equation in slope intercept form y+4=-(x-7)/ Please help I don't get this and I have a final on thursday.

frez [133]

Answer:

$y=-x+3$

Step-by-step explanation:

we have

$y+4=-(x-7)$

This is the equation of the line in point slope form

The equation of the line in slope intercept form is equal to

$y=mx+b$

where

m is the slope

b is the y-intercept

Convert the equation to slope intercept form

remove the parenthesis right side

$y+4=-x+7$

subtract 4 both sides

$y+4-4=-x+7-4$

$y=-x+3$ ---> equation in slope intercept form

find the area of a circke with a radius of 9 mm. round to the nearest tenth. use 3.15 or 22/7 for Pi.

GREYUIT [131]

Answer:

254.3 mm^2

Step-by-step explanation:

Area of a circle: A = π*r^2

π (pi) = 3.14

r (radius) = 9 mm

Substitute 3.14 for pi and 9 for radius:

A = π*r^2

A = 3.14*9^2

A = 3.14*81

A = 254.34 mm^2

Round to the nearest tenth:

254.34 ==> 254.3

Therefore, our final answer is 254.3 mm^2

Hope this helps!
