Answer: B

Step-by-step explanation:

To find the factors, you know that they are known as the zeros. The zeros are located on the x-axis, where the graph crosses. On the graph, we see that the parabola crosses the x-axis at x=-5 and x=-1. Unfortunately, those are not displayed in our answer choices.

We know that each factor is set equal to 0 to get x=?. With this knowledge, let's make it so that we can get factors.

x=-5                                      [add both sides by 5]

x+5=0

Now, we see that it is a factor, (x+5).

x=-1                                     [add both sides by 1]

x+1=0

Now, we see that it is a factor, (x+1).

Our final answer is (x+5) and (x+1) or (x+1) and (x+5).

I need help with question four and the instructions for the equations or just solve the systems of simultaneously equation using
Sliva [168]

Answer:

x = 1\2 and y = 0

Step-by-step explanation:

8x + 3y = 4 * 5\3

14x - 5y = 7 * 1

40\3x + 5y = 20\3 -------- 1

14x - 5y = 7 ----------------- 2

add equation 1 and 2

82\3x = 41\3

x = <u>4</u><u>1</u><u> </u> <u>3</u>

3 * 82

x = 1\2

subtitute 1\2 for x in equation 2

14\2 - 5y = 7

7 - 5y = 7

5y = 7 - 7

y = 0\5

y = 0

thus x = 1\2 and y = 0

Angel lives 3 3 4 blocks to the east of school. Tyrone lives 7 1 4 blocks to the west of Angel. Nadeem lives 8 blocks to the eas
Vladimir79 [104]

Answer:

3 1/2

Step-by-step explanation:

Given that:

Angel lives 3 3/4 blocks to the east of school

Tyrone lives 7 1/4 blocks to the west of Tyrone

Nadeem lives 8 blocks to the east of Tyrone.

Determining each of their homes in terms of distance from school :

Angel = 3 3/4 blocks from school

Tyrone = 7 1/4 blocks to the west of angel

Hence, distance from school will be :

7 1/4 - 3 3/4 = 3 1/2 blocks to the west of school

Nadeem = 8 blocks to the east of Tyrone :

Distance from school will be:

8 - 3 1/2 = 4 1/2 to the east of school.

Hence, 3 1/2 to the west of school is the closet distance of the three.

Hence, Tyrone lives closest to school

Simplify the expression. sine of x to the second power minus one divided by cosine of negative x
slega [8]

Answer:

the answer is the letter a) -sin x

Step-by-step explanation:

Simplify the expression.

sine of x to the second power minus one divided by cosine of negative x

(1−sin2(x))/(sin(x)−csc(x))

sin2x+cos2x=11−sin2x=cos2x

cos2(x)/(sin(x)−csc(x))csc(x)=1/sin(x)cos2(x)/(sin(x)− 1/sin(x))= cos2(x)/((sin2(x)− 1)/sin(x))sin2(x)− 1=-cos2(x)cos2(x)/(( -cos2(x))/sin(x))

=-sin(x)
