Answer:

(a + 2)

Step-by-step explanation:

To factor the quadratic, consider the factors of the constant term which sum to give the coefficient of the a term, that is

factors which multiply to give + 10 and sum to + 7

the required factors are + 5 and + 2, hence

a² + 7a + 10 = (a + 5)(a + 2)

PLAEASE HELP ME <br>If the equation of a line is 2y+3x=3, what is the y intercept of the line?​
Alja [10]

Answer:

3/2

Step-by-step explanation:

2y+3x=3

This represents a linear equation and the format for a linear equation is

y = mx+b

m = slope

b= y-intercept

we have to subtract 3x from both sides to make this the y=mx+b form

2y=-3x+3

and divide both sides by 2

y = (-3x+3)/2

3/2 or 1.5 is the y-intercept

the constant of a linear equation (or 3) is the y-intercept, if there is no constant then the y-intercept is 0
