Answer:

(8, 11 )

Step-by-step explanation:

Given the 2 equations

2x + 2y = 38 → (1)

y = x + 3 → (2)

Substitute y = x + 3 into (1)

2x + 2(x + 3) = 38 ← distribute and simplify left side

2x + 2x + 6 = 38

4x + 6 = 38 ( subtract 6 from both sides )

4x = 32 ( divide both sides by 4 )

x = 8

Substitute x = 8 into (2) for corresponding value of y

y = 8 + 3 = 11

Solution is (8, 11 )

Write an equation to represent the N'th term of the sequence (2,-1.-4,-7,...)

mr_godi [17]

Answer: a(n) = 5 - 3n

the sequence has:

a1 = 2

a2 = -1

a3 = -7

.........

we can see that: a2 - a1 = a3 - a2 = -3

=> the sequence is a arithmetic sequence

=> the distance between the numbers is d = -3

because this sequence is a arithmetic sequence

=> a(n) = a1 + (n - 1)d = 2 + (n - 1).(-3) = 5 - 3n

Line BC has an equation of a line Y equals 2X +3 and F has an equation of a line Y equals -1/2 x+4 these two equations represent

Masja [62]

Answer:

Lines BC and F represent perpendicular lines

Step-by-step explanation:

we have

$y=2x+3$

the slope of the line BC is $m=2$

$y=-(1/2)x+4$

the slope of the line F is $m=-1/2$

we know that

If two lines are perpendicular, then the product of their slopes is equal to -1

$m1*m2=-1$

we have

$m1=2$ -----> slope line BC

$m2=-1/2$ -----> slope line F

Find the product of their slopes

$(2)(-1/2)=-1$

therefore

Lines BC and F represent perpendicular lines

Answer:

B. 1 1/3

Step-by-step explanation:

$\frac{5}{6} + \frac{3}{6} = \frac{8}{6}$

$\frac{8}{6} = \frac{4}{3}$

three can go into 4 once, so we have a whole number of 1 and a leftover 1/3.

= $1\frac{1}{3}$

hope this helps :)
