Answer:

80% of 20 is 16.

Step-by-step explanation:

Hello darling, the answer is 20 ^^

Answer:

The answer is D

Step-by-step explanation:

The line has 2 points: (-1;0) and (0;-4)

=> x1 = -1; x2 = 0 => x1 - x2 = -1 - 0 = -1

   y1 = 0; y2 = -4 => y1 - y2 = 0 - 4 = -4

=> slope = (y1 - y2)/(x1 - x2) = [tex]\frac{-4}{-1}[/tex] = 4 => D

Answer:

m'=7

Step-by-step explanation:

they are parallel to each other so if slope of 1st line be "m" and 2nd line as "m' ", then we have:

m = m'

y-4=7x+14

y=7x+18

y=mx+h

So m = 7

& m' = 7

Answer:

The value of A is 2

Step-by-step explanation:

F = 2 , B = 3 , K = 10

K = F( A + B )

10 = 2(A + 3)

10 = 2A + 6

Now, Subtract 6 from each side we get,

10 - 6 = 2A + 6 - 6

4 = 2A

2A = 4

Now, divide both side by 2 we get,

2A/2 = 4/2

A = 2

Thus, The value of A is 2

K = F( A + B )

10 = 2(2 + 3)

10 = 2(5)

10 = 10

L.H.S = R.H.S

Answer:

The expression would be (x + 3)(x - 8) and if we multiplied those together we would get x^2 - 5x - 24

Step-by-step explanation:

Step-by-step explanation:

So if you multiply both the numerator and denominator by the same number, you get the initial number. Your goal here is to get the same denominator so that you can solve the problem easily! hope it helped!

Answer:

yes

Step-by-step explanation:

[tex]\frac{16}{72}[/tex] ( divide numerator/ denominator by 8, the LCM of 16 and 72 )

= [tex]\frac{2}{9}[/tex]

[tex]\frac{18}{81}[/tex] (divide numerator/ denominator by 9 the LCM of 18 and 81 )

= [tex]\frac{2}{9}[/tex]

Both rational numbers simplify to [tex]\frac{2}{9}[/tex] and are equivalent

Answer:

y = 7/8

Step-by-step explanation:

12y+18=-4y+32

12y+18-18=-4y+32-18

12y=-4y+14

12y+4y=-4y+14+4y

16y=14

16y/16=14/16

y = 7/8

Answer:

[tex]x^{2} +11x-10[/tex]

Step-by-step explanation:

[tex](13x^{2} +9x-4)-(12x^{2} -2x+6)[/tex]

Remove the brackets and multiply the minus sign through all the numbers in the second polynomial

[tex]13x^{2} +9x-4-12x^{2} +2x-6[/tex]

Rearrange in the highest order

[tex]13x^{2} -12x^{2} +9x+2x-4-6[/tex]

Simplify

[tex]x^{2} +11x-10[/tex]

Answer:

[tex]-1\frac{13}{16}[/tex]

Step-by-step explanation:

First let's put our equation to get started

[tex]-3\frac{5}{8}\cdot\frac{1}{2}[/tex]

We can make this an improper fraction by multiplying the integer with the denominator.

Then you would add the total you got with multiplying the total that you got from the whole number and the denominator

[tex]-\frac{29}{8} \cdot\frac{1}{2}[/tex]

Now we can solve it

[tex]-29\cdot1=-29[/tex]

[tex]8\cdot2=16[/tex]

Now our equation is

[tex]-\frac{29}{16}[/tex]

Definition - reduction refers to the rewriting of an expression into a simpler form. For example, the process of rewriting a fraction into one with the smallest whole-number denominator possible

Once we've reduced we will have our equation being

[tex]-1\frac{13}{16}[/tex]

Answer:

8.45

Step-by-step explanation

Convert 65% in decimal form

0.65 x 13 = 8.45

[tex] \sf \: \frac{5}{8} < \frac{3}{8} x - \frac{1}{4}[/tex]

[tex]\sf \longmapsto \frac{5}{8} < \frac{3}{8} x + \frac{ - 1}{4} [/tex]

[tex]\sf \longmapsto \frac{3}{8} x + \frac{ - 1}{4 } > \frac{5}{8} [/tex]

[tex]\sf \longmapsto \frac{3}{8} x + \frac{ -1 }{4} + \frac{ - 1}{4} > \frac{5}{8} + \frac{1}{4} [/tex]

[tex]\sf \longmapsto \frac{3}{8} x > \frac{7}{8} [/tex]

[tex]\sf \longmapsto( \frac{8}{3} ) \times (\frac{3}{8} x) > (\frac{8}{3} ) \times ( \frac{7}{8} )[/tex]

[tex]\sf \longmapsto \: x > \frac{7}{3} [/tex]

Answer:

  8x -3y = 33

Step-by-step explanation:

Multiply by 3 to eliminate the fraction. Then rearrange to standard form.

  y +7 = 2/3(4x -6) . . . . . . . given

  3(y +7) = 2(4x -6) . . . . . . . multiply by 3

  3y +21 = 8x -12 . . . . . . . . eliminate parentheses

  33 = 8x -3y . . . . . . . . . . add 12-3y to both sides

  8x -3y = 33 . . . . . . . . . swap sides to put into standard form

_____

Standard form has mutually prime integer coefficients, the leading one being positive.

Answer:

To calculate the gradient of a straight line we choose two points on the line itself. From these two points we calculate: The difference in height (y co-ordinates) ÷ The difference in width (x co-ordinates). If the answer is a positive value then the line is uphill in direction.
