Answer:

(x-2)(3x²-4 )

Step-by-step explanation:

  1. First, you <u>multiply 3x and 8</u> to equal 24x²
  2. Then, you find the variables that equal -10x (-2x, and -12x)
  3. then <u>replace the -10x with the two variables you found</u> (3x²-2x-12x+8)
  4. Sperate the variable (3x²-2x) and (-12x+8)
  5. Find the <u>GCF</u> of both x(3x-2) and -4(3x-2) (the binomial in the parentheses MUST BE THE SAME
  6. Replace one of the parentheses with x-4
  7. Answer: (x-2) (3x-4)

arsen [322]

Answer:

1/x-2/3=3/2x

-2/3=3/2x-1/x

-2/3=(3-2)/2x

-2/3=1/2x

by cross multiplication

-2(2x)=1(3)

-4x=3

x= -3/4

in a random sample of 150 voters, 60 support Trump. Set up a 96 percent confidence interval for the proportion of voters who sup
denis-greek [22]
Given:
n = 150, sample size
Denote the sample proportion by q (normally written as \hat{p}).
That is,
 q = 60/150 = 0.4, sample proportion.

At the 96% confidence level, the z* multiplier is about 2.082, and the confidence interval for the population proportion is
q \pm z^{*}[ \frac{q(1-q)}{ \sqrt{n} } ]

That is,
0.4 +/- 2.082* √[(0.4*0.6)/150]
= 0.4 +/- 0.0833
= (0.3167, 0.4833)
= (31.7%, 48.3%)

Answer: The 96% confidence interval is about (32% to 48%)

Write an equation to find the nth term. Then find ₐ₂₄<br> -1, -4, -7, -10,...
Maru [420]

The equation to find the nth term is:

an = a+(n-1)d

Where a is the first term in the sequence, which is -1 and d is the difference, which in this sequence the next term is found by subtracting 3 from the previous term, so d = -3 and n is the term you want to find.

The equation becomes:

an = -1 +(n-1)(-3)

a24 = -1 + (24-1)(-3) = -1 + (23(-3)) = -1-69 = -70

A golf player is trying to make a hole-in-one on the miniature golf green shown.
Flauer [41]

The path of the ball is an illustration of absolute equation.

The equation of the path is: y =- \frac{12}7|x- 4.8| + 6.4

The given parameters are:

(h,k) = (4.8,6.4) --- the vertex (i.e. the point where the ball hits the wall)

(x_1,y_1) = (2,1.6)

(x_2,y_2) = (7.6,1.6)

An absolute function is represented as:

y = a |x - h| + k

Substitute (h,k) = (4.8,6.4)

y = a |x - 4.8| + 6.4

Substitute (x_1,y_1) = (2,1.6) for x and y

1.6 = a|2 - 4.8| + 6.4

1.6 = a|- 2.8| + 6.4

Remove absolute bracket

1.6 = 2.8a + 6.4

Collect like terms

2.8a = -6.4+1.6

2.8a =- 4.8

Solve for a

a =-\frac{4.8}{2.8}

Simplify

a =-\frac{12}{7}

Substitute a =-\frac{12}{7} in y = a |x - 4.8| + 6.4

y =- \frac{12}7|x- 4.8| + 6.4

Hence, the equation of the path is: y =- \frac{12}7|x- 4.8| + 6.4

See attachment for graph that models the path
