Answer:

y =-5x-17

Step-by-step explanation:

Slode-intercept is

y = mx + c

The first step is to find the slope, that is the m

To do that, use this formula

Y2 - y1

------------

X2- x1

And u will get - 5

Now since u got m, u also actually have y and x, those are the coordinates they gave u. U can choose either one,(-3, - 2) or (-4, 3), cuz they would give u the same answrs

So let's say I chose (-4, 3)

So x = - 4, y = 3

y=mx +c

3= - 5(-4) +c

C = - 17

Therefore your end product will be

y = - 5x - 17

Answer:

Step-by-step explanation:

There are 26 possibiliteis of the first and last initials. So there are [tex]26\times 26[/tex] different initials.

So the smallest class size to ensure the Prof to use different system is [tex](26\times 26)+1[/tex] since there must be two people in this class with the same first and last initials.

(sin²(x) - 1)/cos(x) = -1

-cos²(x)/cos(x) = -1

-cos²(x) = -cos(x)

cos²(x) - cos(x) = 0

cos(x) (cos(x) - 1) = 0

Then it follows that cos(x) = 0 or cos(x) = 1. But if cos(x) = 0, then the original expression on the left side of the equation would be undefined. Then C is the only valid solution.

Answer:

3.2 cm

Step-by-step explanation:

800 m = 80000 cm (as every meter has 100 cm).

now, on the map that distance goes down 1/25000th of the original distance.

so,

80000 / 25000 = 80/25 = 16/5 = 3 1/5 = 3.2 cm

Answer: KL is 10

Step-by-step explanation:

JL = JK + KL

first get value of x:

[tex]26 = (8x + 8) + (3x + 7) \\ 26 = (8x + 3x) + (8 + 7) \\ 26 = 11x + 15 \\ 11x = 26 - 15 \\ 11x = 11 \\ x = 1[/tex]

therefore,

[tex]KL = 3x + 7 \\ = (3 \times 1) + 7 \\ = 3 + 7 \\ = 10[/tex]

Answer:

Marcia's cord will begin to stretch after [tex]2.24\:\rm{s}[/tex].

Step-by-step explanation:

The expression used to find displacement is given as,

[tex]s=ut+\dfrac{1}{2}at^{2}[/tex]

The initial velocity of Marcia before leaping is zero, so [tex]u=0\:\rm{m/s^{2}}[/tex].

Marcia travels under the influence of gravity and fall freely so the acceleration due to gravity is only acceleration responsible for her movement.

The value for [tex]g[/tex] is [tex]10\:\rm{m/s^{2}}[/tex](approximately) and when it is converted in [tex]\:\rm{ft/s^{2}}[/tex], it is [tex]32\:\rm{ft/s^{2}}[/tex].

Substituting the values, the distance that Marica travels under influence of gravity for [tex]t[/tex] seconds is,

[tex]\begin{aglined}s&=ut+\dfrac{1}{2}at^{2}\\s&=(0)t+\dfrac{1}{2}gt^{2}\\s&=0+\dfrac{1}{2}(32)t^{2}\\s&=16t^{2}\end{aligned}[/tex]

The bungee cord begins to stretch after Marcia has fallen [tex]80\:\rm{ft}[/tex], so

[tex]\begin{aligned}s&=16t^{2} \\80&=16t^{2} \\t^{2} &=5\\t&=2.24\:\rm{s}\end{aligned}[/tex]

Answer:

Step-by-step explanation:

y = x 2 + 91

Explanation:

Let the number be  x

, then  Square of the number is  x ^2

91 more than the square of a number" will be  x^ 2  +  91

So, we can write it as an algebraic expression with two variables as :

y = x ^2  +  91

Answer:

1,558 cases of 12 cans of soup can be made

Step-by-step explanation:

Here, we want to calculate how many cases of cans of soup can be made;

In the first part, we had 325 cases of 24 cans Now, if we split the 24 cans into 2 , we have 12 cans ;

So the number of cases is now 325 * 2 = 650 cases

In the second part, we had 227 cases of 48 cans.

If we split 48 cans into 4 , we can have 12 cans.

So the new number of cases here become 227 * 4 = 908 cases.

So the total number of cases we have will be; 908 + 650 = 1,558 cases

Answer: 7/14 cant be written as a mixed number it is already a proper fraction. sorry I could help

Step-by-step explanation:

Here we have a problem of composition of functions.

Remember that:

(f ° g)(x) = f( g(x) )

Now we have the table:

x      | 1 2 3 4 5 6

f(x)   | 6 4 4 1 6 4

g(x)  | 5 5 2 1 4 3

Using the table, we want to find:

To read the table, for example for f(5) first you go to the "x" part of the table and find the 5.

Now you go to the f(x) table and see which is the value of f(5), in this case, we can see that f(5) = 6.

a)  f(g(1))

First, looking at the table, we can see that:

g(1) = 5

Then:

f(g(1)) = f(5)

Again, looking at the table we can see that f(5) = 6

Then we have:

f(g(1)) = 6

b) g(f(1))

Same approach as before:

f(1) = 6

then g(f(1)) = g(6)

And looking at the table, g(6) = 3

Then:  g(f(1)) = 3

c)  f(f(1))

f(1) = 6

f(f(1)) = f(6) = 4

f(f(1))  = 4

d)  g(g(1))

g(1) = 5

then:

g(g(1)) = g(5) = 4

g(g(1)) = 4

e) (gof)(3)

This is equal to:

(gof)(3) = g(f(3))

we know that f(3) = 4

then:

g(f(3)) = g(4) = 1

(gof)(3) = 1

f) (fog)(6) = f(g(6))

We can see that:

g(6) = 3

then:

f(g(6)) = f(3) = 4

Concluding:

(fog)(6) = 4
