Solve the system of equations below. -3x + 6y = 9 5x + 7y = -49

Step-by-step explanation:

Given system of equations,

-3x + 6y = 9  ------(1)

5x + 7y = -49 ------(2),

LCM (3, 5) = 15,

5 × equation (1) + 3 × equation (2),

We get,

30y + 21y = 45 - 147

51y = -102

From equation (1),

the answer is the option b

the range is all real numbers

step-by-step explanation:

we know that

the absolute value parent function is equal to

see the attached figure to better understand the problem

so

a. it is v-shaped > is true

b. the range is all real numbers > is not true

because the range is the > [0,∞)

all real numbers greater than or equal to zero

c. it goes through the origin > is true

d. the domain is all real numbers > is true

step-by-step explanation:

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
