Apolline is mowing lawns for a summer job. For every mowing job, she charges an initial fee plus a constant fee for each hour of

OLEGan [10]

Answer:

Base Fee = $7

Extra charges = $7

Step-by-step explanation:

Represent the base charge with x and the additiional charges with y.

For the 5 hours job, we have:

$42 = x + 5y$

For the 3 hour job

$28 = x + 3y$

Solving for x and y;

$42 = x + 5y$

$28 = x + 3y$

Subtract the second equation from the first

$42 - 28 = x - x + 5y - 3y$

$14 = 2y$

Solve for y

$y = 14/2$

$y = 7$

Substitute 7 for y n the first equation

$42 = x + 5y$

$42 = x + 5 * 7$

$42 = x + 35$

$x = 42 - 35$

$x = 7$

Write the absolute value inequality in the form

yawa3891 [41]

Answer:

$\large\boxed{|x+7|\geq2}$

Step-by-step explanation:

Look at the picture.

$|x-a|\geq b\\\\a=\dfrac{-9+(-5)}{2}=\dfrac{-14}{2}=-7\\\\b=-9-(-7)=-9+7=-2\\b=-5-(-7)=-5+7=2\\\\|x-(-7)|\geq2\\\\|x+7|\geq2\\\\Check:\\\\|x+7|\geq2\iff x+7\geq2\ \vee\ x+7\leq-2\qquad\text{subtract 7 from both sides}\\\\x+7-7\geq2-7\ \vee\ x+7-7\leq-2-7\\\\x\geq-5\ \vee\ x\leq-9\qquad CORRECT\ :)$

PLEASE HELP! WILL GIVE YOU BRAINLEST

Answer: b

the answer is b

in order to solve for AB you need to use the pythagorean theorem by making a triangle with AB as one of the sides of the triangle.

plot each point A and B and connect it and connect point B with the x-axis, (3,0) You'll see athat a triangle has formed. All you have to do after that is apply the Pythagorean theorem.

the distance from A to the new point (3,0) is 3, the distance from the new point to B is 4. Line AB will be the hypotenuse.

Pythagorean therom is a^2+b^2=c^2

so 3^2+4^2=c^2

= 9+16=25

square root the 25 and you get a 5.
