Answer: a. 15/2

Step-by-step explanation:

\frac{2}{3}x-1=4\\ \frac{2}{3}x=5\\x=\frac{5}{\frac{2}{3} } \\x= 5* \frac{3}{2} \\x=\frac{15}{2}

Answer:

14,300,000

Step-by-step explanation:

Starting off with 14 million, you haven't reached the 100 thousands or below yet where you should start. The next digit, 3, is in the 100 thousands place and the digit next to it is four. When you're rounding, if the digit is greater than five, then you round up. (example: if the number you're rounding is 67, seven is greater than five so you would round it to 70.) If the digit you are rounding is smaller than 5 then you would round down. (Example: if the number you're rounding is 34, then you would round down because four is smaller than five or higher.) Since in your problem, you have 345,678, (we've already discussed the 14 million part in the beginning) 4 is smaller than 5 or higher so it would round 14,345,678 to 14,300,678. However, since we've already rounded the part we meant to do, every digit after would turn to 0. The final result would be 14,300,000.

PLEASE HELP. WILL GIVE BRAINLIEST
KengaRu [80]

Answer:

x-intercepts = 1,2, and 4, y-intercept = -8

Step-by-step explanation:

x^3 - 7x^2 - 14x - 8 in factored form is equal to (x-1)(x-2)(x-4).

Solving for x-intercepts:

  • We are actually able to solve for all x-intercepts without the given factor. But since we are given one of the factors, our job becomes much easier.
  • Using synthetic division, or long division, we factor out the x-intercept 4. Which leaves us with the polynomial x^2 - 3x + 2.
  • From here we can separate the polynomial into two binomials.
  • x^2 - 3x + 2 = (x-1)(x-2). Giving us all 3 x-intercepts.
  • Using Descartes' rules we can identify before even starting the problem how many real x-intercepts there are (Not needed for this problem).

Solving for y-intercept:

  • The y-intercept is always the coefficient that does not have any assigned x-variables.
  • The coefficient is -8, thus the y-intercept.
  • If unsure of the y-intercept, you can always plug in x = 0. Solving for the y-intercept will give you the value of f(0).
  • If there is no coefficient, the y-intercept is equal to zero.

How do i solve this step by step? i dont know how to set up this equation.
zmey [24]

Answer:

Step-by-step explanation:

The two long sides on the left and right and bisected into two equal parts each

That means that since there is an angle in common to the top little triangle and the whole diagram, the little triangle on top and the whole triangle are similar.

The ratio of similarity is 1/2

10/(5x + 5) = 1/2                              Cross multiply

(5x + 5)*1 = 10*2

5x + 5 = 20                                     Subtract 5 from both sides

5x = 20 - 5                                     Combine

5x = 15                                            Divide by 5

5x/5 = 15/5

x = 3

2. 1.29

3. 9.90

Step-by-step explanation:

They are buying 5 of each thing, so multiply it by 5.

The diced tomatoes cost $1.29.

When you solve the equation, you get 9.9. Convert that to money, and you have $9.90
