Pls help Zoey is trying to write an equation in slope intercept form. She knows slope intercept form is y=mx+b. She is given the slope is 3 and the y intercept is 10. When she plugs it in she gets 10=3x+b. What mistake did zoey make and how can she fix it?

Answers

Answer:

the mistake that zoey had made while writing the equation was putting the y-intercept in the wrong place.in the slope intercept from the equation is y=mx+b.y is the product or the line, m is the slope, b is the y-intercept, the actual equation should be y=3x+10,instead what zoey had which was 10=3x+b. she guessd by pairing the y-intercept with y instead of b.

Solve for y.-5y - 9 = -(y - 1)

Answer choices:
a. -1/2
b. -2 1/2
c. -2
d. -2/5

I am brain-dead. :|

Answers

-5y - 9 = -(y - 1)

First, simplify your brackets. / Your problem should look like: $-5y - 9 = -y + 1$
Second, regroup the terms. / Your problem should look like: $-5y - 9 = 1 - y$
Third, add 5y to both sides. / Your problem should look like: $-9 = 1 - y + 5y$
Fourth, simplify 1 - y + 5y to 1 + 4y. / Your problem should look like: $-9 = 1 + 4y$
Fifth, subtract 1 from both sides. / Your problem should look like: $-9 - 1 = 4y$
Sixth, subtract -9 - 1 to get -10. / Your problem should look like: $-10 = 4y$
Seventh, divide both sides by 4. / Your problem should look like: $-(10)/(4) = y$
Eighth, simplify $(10)/(4)$ to $(5)/(2)$ / Your problem should look like: $- (5)/(2) = y$
Ninth, switch your sides. / Your problem should look like: $y = -(5)/(2)$

Answer: y = $-(5)/(2)$
Answer as decimal: y = -2.5

Answer:

y = -2 $(1)/(2)$

Step-by-step explanation:

-5y - 9 = -(y - 1)

-5y - 9 = -y + 1

-5y + y = 1 + 9

-4y = 10

$(-4y)/(-4)$ = $(10)/(-4)$

y = -2 $(2)/(4)$ Simplify

y = -2 $(1)/(2)$

Fill two of the pools with water, Each pool will be filled to a depth of 5 feet. The other necessary dimensions are given below. How much water is necessary for each of the elements below? The isosceles triangle pool: height 20ft and base 35ft
The equilateral triangle pool: height 52ft and base 60ft

Answers

Find the volume of each pool. The formula for triangular prisms is length*width*height*1/2. Or, since your numbers give the base, you can just multiply the height and the base, then multiply by 5, then divide by 2 to get the answer.
So, 20*35*5/2 = 1,750 ft³ is the equation for the isosceles triangle, and the equilateral triangle pool is 52*60*5/2 = 7,800 ft³.
The volume = how much water you need for each pool.
Hope that answered your question.

Write the fraction in simplest form 5/10

Answers

The fraction 1/2 represents the same value as 5/10, but it is expressed in its simplest form because the numerator and denominator have no common factors other than 1.

To simplify the fraction 5/10, we can reduce it to its simplest form by finding the greatest common divisor (GCD) of the numerator and denominator and dividing both by it.

In this case, the GCD of 5 and 10 is 5. By dividing both the numerator and denominator by 5, we get:

5/10 = (5 ÷ 5) / (10 ÷ 5)

= 1/2.

Therefore, the simplified form of the given fraction 5/10 is 1/2.
