Answer 1
Answer:

Option B:

Equation of the line of best fit in slope-intercept form is y=(1)/(2)x+1.

Solution:

Take two points on the line (0, 1) and (4, 3).

So, x_1=0, y_1=1, x_2=4, y_2=3.

Slope of the line:

$m=(y_2-y_1)/(x_2-x_1)

$m=(3-1)/(4-0)

$m=(2)/(4)

$m=(1)/(2)

y-intercept means the point which crosses at y-axis.

Here the point on the y-axis is (0, 1).

y-intercept (b) = 1

Slope-intercept form:

y = mx + b

$y=(1)/(2)x+1

Equation of the line of best fit in slope-intercept form is y=(1)/(2)x+1.

Option B is the correct answer.

I = P x r x t

P is the principal amount, $420.00.

r is the interest rate, 3.5% per year

t is the time involved, 5 years

420 × 0.035 × 5 = 73.50

73.50 + 420 = 493.5

kayley is saving money for a vacation she starts out saving 10 dollars a week she plans to double the amount she is saving each month how much money will she be saving the fourth month.

Answers

4 weeks in a month. 

1st month; 10 x 4 = $40
2nd month; 40 x 2 = $ 80 
3rd month; 80 x 2 = $160
4th month; 160 x 2 = $320

40 + 80 + 160 + 320 = $ 600

ok ratio and proportion
realheight:shadow=15:20

slide shadow=16
therefor find realheightslide

15:20=realheightslide:16
simplify
3:4=realheight:16
fractionfy
3/4=realheight/16
multiply both sides by 16
48/4=realheight

square? Remember, this is a two-step process​

Answers

ANSWER

The correct answer is D

EXPLANATION

The given quadratic expression is

3 {x}^(2)  + 8x =  - 1

Divide through by 3

{x}^(2)  +  (8)/(3) x =  -  (1)/(3)

We now add the square of half the coefficient of x because the coefficient of the quadratic term is now unity.

The constant we would add is

{( (4)/(3) )}^(2)  =  (16)/(9)

The correct answer is D

Answer: Option D.

Step-by-step explanation:

Given the quadratic equation 3x^2+8x=-1, you can observe that the leading coefficient is not 1, then you have to divide both sides of the equation by 3:

(3x^2+8x)/(3)=(-1)/(3)\n\nx^2+(8)/(3)x=(-1)/(3)

Now, you can observe that the coefficient of the x-term is (3)/(8), so you must divide it by 2 and square it. Then you get:

(((8)/(3))/((2)/(1)))^2=(16)/(9)

Therefore, you must add (16)/(9) to both sides of the equation.
