Math homework. Please help me! What is the x-coordinate of the solution? Y=4x+9 Y=-1+8x

So, first set the two Y values equal to each other.

4x+9 = -1+8x

Add and subtract values to both sides making the x coordinates on one side:

4x = 10

Finally, divide.

x = 10/4 = 2.5

Translate and solve: fifty times n is at most 500.<br><br> Give your answer in interval notation.
andrey2020 [161]

Answer: (-infinity,10]

Step-by-step explanation: 50n is less than or equal to 500. So, treat the less than or equal to sign as an equal sign. Then do like regular and divide 500 by 50 to get ten on the right while N stays on the left. To get n is greater than or equal to 10!

A manufacturer knows that their items have a normally distributed length, with a mean of 10.2 inches, and standard deviation of
ArbitrLikvidat [17]

Answer:

P [ X ≤  9.8 ]  = 0.1335

Step-by-step explanation:

P [ X ≤  9.8 ]  =  [ ( 9.8  - 10.2 )/1.8√25 ]

P [ X ≤  9.8 ]  =  - 0.4*5/1.8

P [ X ≤  9.8 ]  = - 2 / 1.8

P [ X ≤  9.8 ]  =  - 1.11

From z- table we get:  α  =  0.1335

P [ X ≤  9.8 ]  = 0.1335   or   P [ X ≤  9.8 ]  = 0.1335

in the past year tom watched 4 movies that he thought were very good. he watched 40 movies over the whole year. Of the movies he
balandron [24]
10% of the movies, because 100/40 is 2.5 so you would do 4 x 2.5 which equals 10. AKA
So if you’re trying to change it to x/100, you would do cross division and get 10/100 which equals 10%

Z to the power of 2 =1
stiv31 [10]

That would be written as:

z^{2} = 1


And the step-by-step equation would be:

z^{2} = 1 → we take the 2 to the right side of the equation and do the IO*

z = \sqrt{1} →we solve for \sqrt{1}

z = 1 → final answer


*Ps - IO is not an existing term and stands for inverse operation. In this case, because when we take to 2 to the right side of the equation (the 2 is a power) it'll have to turn into a square root (because exponents and roots are inverse operations)



Hope it helped,
