Which equation represents the relationship between x and y shown in the table?

Hunter-Best [27]

Answer:

y=2x-3

Explanation:

which equation represents the relationship between x and y shown in the table?

x | y

2 | 1

4 | 5

6 | 9

8 | 13

take a look at the values in the table one more,

we find the gradient of the line to be

G=y2-y1/(x2-x1)

G=13-1/(8-2)

slope/gradient=12/6

m=2

from equation of a line graph, we know

y=mx+c

m=gradient

c=intercept

y=vertical axis

x=a point on the horizontal axis

y=2x+c

when x=6, y=9

9=2(6)+C

c=-3

Therefore the equation becomes

y=2x-3

Rewrite the fraction pairs with common denominators

Nataliya [291]

Answer:

a) $\frac{3}{20}$ and $\frac{16}{20}$ = $\frac{19}{20}$

b) $\frac{8}{21}$ and $\frac{18}{21}$ = $1\frac{5}{21}$

c) $\frac{18}{72}$ and $\frac{32}{72}$ = $\frac{25}{36}$

Step-by-step explanation:

a) $\frac{3}{20}$ and $\frac{4}{5}$

$\frac{4}{5}$ x 4 = $\frac{16}{20}$

$\frac{3}{20}$ and $\frac{16}{20}$ = $\frac{19}{20}$

b) $\frac{8}{21}$ and $\frac{6}{7}$

$\frac{6}{7}$ x 3 = $\frac{18}{21}$

$\frac{8}{21}$ and $\frac{18}{21}$ = $1\frac{5}{21}$

c) $\frac{2}{8}$ and $\frac{4}{9}$

$\frac{2}{8}$ x 9 = $\frac{18}{72}$

$\frac{4}{9}$ x 8 = $\frac{32}{72}$

$\frac{18}{72}$ and $\frac{32}{72}$ = $\frac{25}{36}$

OlgaM077 [116]

If x is the smallest integer, then the next consecutive integer is x+1, and the third consecutive integer is x+2
Solve:
$x+x+1+x+2=-54\\3x+3=-54\\3x=-57\\x=-19$
>the smallest integer is -19
