Type a digit that makes this statement true.

Aneli [31]

Answer:

1, 3, 5, 7, or 9

Step-by-step explanation:

For 14, 213, 1__2 to be divisible by 4, the last two digits must be divisible by 4.

Using this knowledge, any odd single digit number would make the statement true.

14, 213, 112 ÷ 4 = 3, 553, 278

14, 213, 132 ÷ 4 = 3, 553, 283

14, 213, 152 ÷ 4 = 3, 553, 288

14, 213, 172 ÷ 4 = 3, 553, 293

14, 213, 192 ÷ 4 = 3, 553, 298

Hope this helped!

For the straight line defined by the points (3,57) and (5,87), determine the slope ( m ) and y-intercept ( ???? ). Do not round

Sphinxa [80]

Answer: The slope of the line is 15 and y-intercept is 12.

Step-by-step explanation: We are given to find the slope and y-intercept of the straight line defined by the points (3, 57) and (5, 87).

We know that

the slope of a line passing through the points (3, 57) and (5, 87) is given by

$m=\dfrac{87-57}{5-3}=\dfrac{30}{2}=15.$

Since the straight line passes through the point (3, 57), so its equation will be

$y-57=m(x-3)\\\\\Rightarrow y-57=15(x-3)\\\\\Rightarrow y-57=15x-45\\\\\Rightarrow y=15x-45+57\\\\\Rightarrow y=15x+12.$

So, the required equation of the straight line is $y=15x+12.$

Thus, the slope of the line is 15 and y-intercept is 12.

One half of 780 fans stood and cheered.how many fans stood and cheered?what percent of the fans stood and cheered?

Liula [17]

390 fans cheered because 780 divided by 2 is 390

the percent is 50% because one half is equal to 50%(take 100 for example)

20 points! Simplify: 2y(2y+3yx^{2} )-y^{2} (3-y) please show work!

arlik [135]

Answer:

8x2y - 6x2 - 8xy2 - y2

Step-by-step explanation:

Equation at the end of step 1 :

(((((5•(x2))•y)-(5•(x2)))+(3y•(x2)))-(3•(y2)))-((((x2)+(y2))+(8x•(y2)))-3y2)

Step 2 :

Equation at the end of step 2 :

(((((5•(x2))•y)-(5•(x2)))+(3y•(x2)))-(3•(y2)))-((((x2)+(y2))+23xy2)-3y2)

Step 3 :

Equation at the end of step 3 :

(((((5•(x2))•y)-(5•(x2)))+(3y•(x2)))-3y2)-(x2+8xy2-2y2)

Step 4 :

Equation at the end of step 4 :

(((((5•(x2))•y)-(5•(x2)))+3x2y)-3y2)-(x2+8xy2-2y2)

Step 5 :

Equation at the end of step 5 :

(((((5•(x2))•y)-5x2)+3x2y)-3y2)-(x2+8xy2-2y2)

Step 6 :

Equation at the end of step 6 :

((((5x2•y)-5x2)+3x2y)-3y2)-(x2+8xy2-2y2)

Step 7 :

Final result :

8x2y - 6x2 - 8xy2 - y2
