Answer:

Ordered pair, (1, 5/2) does not satisfy the given equation 3x-3y=-3

Step-by-step explanation:

$3x-3y=-3$

Here $(x, y) = (1, \frac{5}{2} )$

$3(1)-3(\frac{5}{2} )=-3$

$3- (\frac{15}{2} )=-3\\6-15=-6\\-9\neq -6$

Find the gcf and use it to reduce 36/63

alisha [4.7K]

Answer:

$\frac{4}{7}$

Step-by-step explanation:

The greatest common factor of 36 and 63 is 9.

Thus, $\frac{36}{63}$ = $\frac{4}{7}$ since (36 ÷ 9 = 4) and (63 ÷ 9 = 7).

A point Q on a segment with endpoints A (2, −1) and C (4, 2) partitions the segment in a 4:1 ratio. Find Q.

Annette [7]

The point Q on a line segment with end points(2,1) and (4,2) is Q(12/5, -2/5)

<h3>What is a line segment?</h3>

A line segment is a straight line that passes through two given points.

The end points of the line determine how long or short a given line segment would be.

Analysis:

point Q(x, y )

x = $\frac{MX1 + NX2}{M+N}$

y = $\frac{MY1 + MY2}{M+N}$

where M :N = 4:1

x1 = 2, x2 = 4, y1 = -1, y2 = 2

x = $\frac{4(2) +1(4)}{4+1}$ = 12/5

y = $\frac{4(-1) + 1(2)}{4+1}$ = -2/5

In conclusion, the point Q is (12/5, -2/5).

Someone help me with number 8

Gnesinka [82]

Answer:

The answers are...:

The common ratio is -3

the sequence of the function is 2,-6, 18, -54, 162

and

the sequence of the function model is geometric

I hope this helps ^^"

Step-by-step explanation:

the common ratio is just from the -3 itself

the sequence model is just plugging n for every term so

a(1) would equal to 2, a(2)=-6 , a(3) would equal to -18, etc

and the geometric is bc it has the exponential that has (n-1), thus it is a geometric sequence
