If the line through (-2,4)and ) 5,D)is parallel to the graph of y= 3X +4 find the value of d

Answers

Answer:

D = 25

Step-by-step explanation:

For 2 lines to be parallel, they must have the same sloe;

Given the coordinates (-2,4)and (5,D)

Slope = D-4/5-(-2)

Slope = D-4/5+2

Slope = D-4/7

Given the equation y = 3x + 4, comparing to y = mx+b

mx = 3x

m = 3

Hence the slope is 3

Equating the slopes

D-4/7 = 3

D-4 = 3*7

D-4 = 21

D = 21+4

D = 25

Hence the value of D is 25

Answer:

  record 6 hundredths; add 4 to the numbers of tenths

Step-by-step explanation:

Nicholas needs to write down the 6 and "carry" the 4, adding it to the numbers of tenths.

Depending on the method you've been taught, the 4 may be written above the column with place value of tenths, or it may be written on a separate sum line.

Principal, $3000; Annual interest rate, 5.4%; time, 5 years

Answers

Answer:

SI = $810

Amount = $3,810

Step-by-step explanation:

Given that ,

P = $ 3,000 R = 5.4% T = 5 yrs .

We can use the formula of SI to find the interest as ,

=> SI = P × R × T / 100

=> SI = $ 3000 × 5.4 × 5 / 100

=> SI = $ 30 × 5.4 × 5

=> SI = $ 810 .

If you want to know total amount , then ,

=> Amount = SI + P

=> Amount = $ 810 + $ 3,000

=> Amount = $ 3,810

Hence the Amount is $3,810 and the SI is $810 .

Answer:

Step-by-step explanation:

3000*(.054)(5)= $810

Edgar has a bag of 10 marbles (3 green, 5 blue, and 2 red). If he picks one marble out of the bag at random, what’s the probability that he will get a blue marble? Explain how you determined that probability.

I need to find the value of x help needed

Answers

Answer:

x=33°

Step-by-step explanation:

Hi there!

We're given a triangle, with 2 known measures of angles in the triangle

54° and 93°

the other (unknown) value is x

the angles in a triangle add up to 180°

therefore, to find the value of x, we can add up the values of the 3 angles and set that to equal 180

54°+93°+x°=180°

add 54 and 93

147°+x°=180°

subtract 147 from both sides

x=33°

so the value of x is 33 degrees

Hope this helps!

please help me answer these 2 questions, worth lots of points

Answers

For the first one, to find x, you are going to take that entire side which would equal to 180 and solve. 2x+20+55=180 would then go down to 2x+65=180 once you add the 20 and 55. Then subtract 65 to both sides and divide your final answer 115/2 which is x=57.5. For the second one it’s 4x-2+21=180, then you will subtract 2 from 21 and get 19. After you would subtract 19 by 180 and divide 4 by each side, getting x=40.25 as your final answer.

Answer:

  none of the function pairs are inverses

Step-by-step explanation:

Inverse linear functions will meet all of several requirements:

each is a reflection of the other about the line y=xthe solution of the simultaneous equations in on the line y=xin standard form, the coefficients are swapped (only)the product of the slopes is 1

_____

For these problems, it is probably easiest to look at the last requirement. Each function is given in slope-intercept form, so the slope is simply the x-coefficient.

5) The product of slopes is (-2)(-1) = 2 ≠ 1 . . . NOT inverses

6) The product of slopes is (-1)(1/3) = -1/3 ≠ 1 . . . NOT inverses

7) The product of slopes is (-4/3)(-1/2) = 2/3 ≠ 1 . . . NOT inverses

8) The product of slopes is (3/2)(-5/2) = -15/4 ≠ 1 . . . NOT inverses
