<span>f(x)=4x²-15x-25
</span><span>f(x)=(4x + 5)(x - 5)

</span><span>zero-product property 
let </span>f(x)=(4x + 5)(x - 5) = 0
so
(4x + 5)(x - 5) = 0
4x +5 = 0
4x = -5
  x = -5/4
  x = -1.25

x - 5 =0
x = 5

answer
factor: (4x + 5)(x - 5)
x = 5 and x = -1.25

A triangular playground has angles with measures in ratio 8: 3: 9 what is the measure of the smallest angle
maria [59]
8x + 3× + 9x = 180

20x = 180
x = 180/20
x = 9

The smallest angle is: 3×9 = 27 degrees

Note: 180 degrees is the sum of angles in a triangle

Write an inequality <br> the sum of 1 and x is less than 5.<br><br> 3 is less than y minus 2
bagirrra123 [75]

If an expression has an equal to sign, it is called an equation.

If it has less than or greater than sign, then it is called inequality.

It is also an inequality if it has greater than or equal to or less than or equal to signs. ( ≥, ≤)

The sum of 1 & x is x+1

This sum is less than 5

So we have

x + 1 < 5

Now y minus 2 means

y - 2

Now it says 3 is less than (y-2)

So we get

3 < y - 2

1)

the sum of 1 and x is less than 5 => x + 1 < 5

2)

3 is less than y minus 2 => 3 < y - 2

(-10) - (-4)

-10 +4 (because negative multiply by negative is positive)

= -6 (because -10+4 means different signs means you subtract and get the sign of the bigger number)

9. Consider an experiment that consists of determing the type of job (either blue-collar or white-collar) and the political affi
kari74 [83]

Answer:

6^{15}

Step-by-step explanation:

An outcome is a possible result of an event. Sample space is the set of all possible outcomes.

An event is a subset of the sample space.

Let B, W denotes blue-collar, white-collar respectively.

Let R, D and I denotes republican, democrat, or independent respectively.

Number of members of an adult soccer team = 15 members

To find:Number of outcomes

Sample space:

S=\left \{ \left ( (x_1,y_1),(x_2,y_2),...,(x_{15},y_{15}) \right )|x_i\varepsilon \left \{ B,W \right \} \,,\,y_i\varepsilon \left \{ R, D, I \right \}\right \}

So. n(S) = \left ( 2\times 3 \right )^{15}=6^{15}
