Using what you have learned about solving systems of equations, find the number that represents the apple, banana, and cherry.

sineoko [7]

Answer:

$Apple \to 4$

$Banana \to 4$

$Cherry \to 5$

Step-by-step explanation:

Given

$A \to Apple$

$B \to Banana$

$C \to Cherry$

From the rows, the equation is:

$B + 2A =12$ --- (1)

$2B + C = 13$ --- (2)

$A + 2C = 14$ --- (3)

Make A the subject in: $A + 2C = 14$

$A = 14 -2C$

Substitute $A = 14 -2C$ in $B + 2A =12$

$B + 2(14 - 2C ) = 12$

$B + 28 - 4C = 12$

Make B the subject

$B = 4C - 28 +12$

$B = 4C -16$

Substitute $B = 4C -16$ in $2B + C = 13$

$2(4C - 16) + C = 13$

$8C - 32 + C = 13$

Collect like terms

$8C + C = 13+32$

$9C = 45$

Divide by 9

$C = 5$

Recall that:

$B = 4C -16$

$B =4*5-16$

$B =20-16$

$B =4$

Recall that:

$A = 14 -2C$

$A= 14 -2*5$

$A= 14 -10$

$A =4$

Hence:

$Apple \to 4$

$Banana \to 4$

$Cherry \to 5$

Write two mixed nubers that have the sum of 3

erastova [34]

A mixed number is a number that is a whole number with a fraction
so numbers that are mixed are greater than 1

so therefor since both have to be greater than 1, the fractions have to add up to equal 1

so the mixed numbers are (1 and x) and (1 and y) where x+y=1 so some examples are
1 and 1/2+1 and 1/2
1 and 1/3+1 and 2/3
1 and 1/4 +1 and 3/4
1 and 1/1000+1 and 999/1000
etc

What is the x-intercept (-5,-5) (10,-2)

Andre45 [30]

Answer:

(20,0)

Step-by-step explanation:

slope = (y2 - y1) / (x2 - x1)

(-5,-5).....x1 = -5 and y1 = -5

(10,-2)...x2 = 10 and y2 = -2

slope = (-2 - (-5) / (10- (-5) = (-2 + 5) / (10 + 5) = 3/15 = 1/5

y = mx + b

slope(m) = 1/5

use either point, I will use (10,-2)...x = 10 and y = -2

now we sub

-2 = 1/5(10) + b

-2 = 2 + b

-2 - 2 = b

-4 = b

so the equation for this line is : y = 1/5x - 4

to find the x intercept, sub in 0 for y and solve for x

y = 1/5x - 4

0 = 1/5x - 4

-1/5x = -4

x = -4 * -5

x = 20.......so ur x intercept is (20,0) <====
