1 answer:

8 0

1) Prime
2) (x + 5)(x − 1) = x²-1x+5x-5= x²+4x-5
3) (x − 5)(x − 1)= x² -1x -5x +5= x² -6x +5
4) (x + 5)(x + 1) = x² +1x +5x+ 5x = x² +6x+5

It is 1) Prime

Help me plssssssssss

Amanda [17]

Answer:

Answer:  y = x + 1 

Step-by-step explanation:

${ \tt{y = - 3x + 5}}$

» At point of intersection:

${ \tt{2 = - 3x + 5}} \\ { \tt{ - 3x = - 3}} \\ { \tt{x = 1}}$

» Point of intersection is (1, 2)

• General equation of a line:

${ \tt{y = mx + c}}$

m is slope
c is y-intercept

» Consider point (1, 2);

${ \tt{2 = (1 \times 1) + c}} \\ { \tt{c = 2 - 1}} \\ { \tt{c = 1}}$

Equation:

${ \tt{y = x + 1}}$

mina [271]

The pattern is adding 1.43 to the term before

1.11 + 1.43 = 2.54 + 1.43 = 3.97 + 1.43 = 5.40 . . .and so on.

2 thirds of the product of 3 octavos and 16

Mazyrski [523]

Answer:4

Step-by-step explanation:

finding the product of 2 numbers means that you have to multiply those numbers

when multiplying fractions , numerators are multiplied by numerators and denominators by denominators

therefore product of 3/8 and 16 is 6

next we have to find 2/3 of 6

'of' operator means multiplication

answer is 4

hope it helps
