Solve: −3(5+8x)−20≤−11

Tatiana [17]

-3(5 + 8x) - 20 ≤ -11 |use distributive property: a(b + c) = ab + ac

-15 - 24x - 20 ≤ -11

-35 - 24x ≤ -11 |add 35 to both sides

-24x ≤ 24 |change signs

24x ≥ -24 |divide both sides by 24

x ≥ -1

The roots of a quadratic function are x = -3 and x = 2/3. Which of the following would be the constant term of the equation in s

Alla [95]

Answer:

-2

Step-by-step explanation:

Since the roots are known and the function is a quadratic function, we can write down the function:

y = (x+3)(x-2/3) since when the roots are plugged in, the function gives 0.

Standard form means that the function has to be expanded:

y = (x+3)(x-2/3) = $x^{2}+3x - 2x/3 - 3*2/3$

y = $x^{2}+ 7x/3 - 2$

The constant term is -2.

I need help finding the lowest term for -8/9+11/15

Liono4ka [1.6K]

Answer:

-7/45

Step-by-step explanation:

First, find the lowest common denominator for 9 and 15. It's 45. Make both fractions over 45 by multiplying the top and bottom by the same number.

$-\frac{8}{9} +\frac{11}{15}$

$= -\frac{8*5}{9*5} +\frac{11*3}{15*3}$ Since 15*3=45, multiply the top by 3 also. Since 9*5=45, multiply the top by 5 also.

$= -\frac{40}{45} +\frac{33}{45}$

$= \frac{-40+33}{45}$ Combine the fractions

$= -\frac{7}{45}$ Answer in lowest terms
