PLEASE HELP ASAP!!!! SUPER URGENT

Mathematics
1 answer:
DochEvi [55]3 years ago
6 0

Answer:

y = 2(x + 3)(x + 1)

Step-by-step explanation:

Use the formula y = a(x-b)(x-c)

b and c are the x-intercepts

The x-intercepts in this function are -3 and -1

y = a(x+3)(x+1)

substitute the point (-2, -1)

-2 = a(-2 + 3)(-2 + 1)

-2 = a(1)(-1)

-2 = -a

a = 2

y = 2(x + 3)(x + 1)

Which point on the number line is located at approximately 13/17
Dmitry_Shevchenko [17]
A number line consists only of one axis, conventionally a horizontal axis. Just create a line, and scale it according to practicality and your preference. Usually, it has an interval of 1 unit. But for this case, since it is in fraction form, the interval should be smaller so that you can see clearly where it is located. 

In decimal form, 13/17 is equal to 0.7647058824. Let's just round this off to 0.764, that can suffice already. So, you would expect it to be between 0.7 and 0.8 on the number line. Just estimate visually where it is located. Since, it is more than 0.75, the dot would be just slightly closer to 0.8 than 0.7. The exact location is shown in the attached picture.

Solve the equation: n + 32 = 60.
Digiron [165]
N + 32 = 60

First, so basically, we are trying to find a number that can add up with 32 to equal 60. The easiest route to solve this is to simply take 32 and subtract it from 60.
n = 60 - 32

Second, once we subtract, we will be given the answer and know what 'n' is. Subtract 60 - 32 to get your answer. 60 - 32 = 28
n = 28

Third, know that we know that the answer to 'n' is 28, we can check it by adding 28 + 32. Your answer should be 60, and 28 is the correct answer.

Answer: \fbox {n = 28}

The graph of the function f(x) = -(x+6)(x + 2) is shown
Leokris [45]

Answer:

The function is increasing for all real values of x where

x < –4.

Step-by-step explanation:

we have

f(x)=-(x+6)(x+2)

This is a vertical parabola open downward (the leading coefficient is negative)

The vertex (h,k) represent  a maximum

The roots of the function (or x-intercepts) are x=-6 and x=-2

The x-coordinate of the vertex is the midpoint of the roots

so

h=(-2-6)/2=-4

The y-coordinate of the vertex is

substitute the x-coordinate of the vertex in the quadratic equation

k=-(-4+6)(-4+2)

k=-(2)(-2)

k=4

The vertex is the point (-4,4)

The function is increasing in the interval (-∞,-4)

The function is decreasing in the interval (-4,∞)

A scale drawing of a car uses a scale of 2cm =1m. What is the length of the car on the drawing if the actual car measures 4 m?
marusya05 [52]

Answer:

The answer is 8cm.

Step-by-step explanation:

The scale drawing uses a ratio of 2cm:1m. If the actual car is 4 meters long, you would multiply 2 by 4 to get 8cm. The actual new ratio on the map is 8cm:4m, which is equivalent to the one in the problem.
