Answer:

1000-a=400

a = 400 - 1000

a= -600

Answer:

1000-a=400

Step-by-step explanation:

or, -a=400-1000

or,-a= -600

therefore - and - cutting then

Answer:

39 sweets

Step-by-step explanation:

the sum of the ratio is

1+4+4= 9

to find the number of sweets shared we say

1/9*X=13 sweets

X=9*13

X=117

therefore Gavin and jim will share equal number of sweets

117-13

104 sweets. Jim gets 52 while Gavin gets 52 sweets.

How many more sweets does Gavin get over Stephen?​

52-13

Gavin get 39 more sweets over Stephen. I hope that helps

Answer:

8/13

Step-by-step explanation:

(−4,−4);(9,4)

(x1,y1)=(−4,−4)

(x2,y2)=(9,4)

Use the slope formula:

m=

y2−y1

x2−x1

=

4−−4

9−−4

Answer: 8/13

Step-by-step explanation:

[tex]m = \frac{y_{2}-y_{1} }{x_{2} -x_{1} }[/tex]

[tex]m = \frac{4 -(-4) }{9-(-4) }[/tex]

[tex]m = \frac{4 +4 }{9+4 }= m = \frac{8}{13 }[/tex]

Slope is 8/13

Step-by-step explanation:

Answer:

Positive: (-2,1)

Negative: (-∞,-2) U (1,∞)

Step-by-step explanation:

The graph of the function f(x) is given in the figure. We can see some points like (-2,0), (-1,1), (2,-2), and many others.

Note the second value of each point (the value of y) is positive or negative. When it's positive, the graph is above the x-axis, when it's negative, the graph is below the x-axis. When it's 0, the graph crosses the x-axis.

To find the intervals of x where the function is positive, we only have to look into the zone where the graph is above the x-axis. It can be identified as the interval (-2,1).

Similarly, the function is negative in the interval (-∞,-2) U (1,∞)

The function f(x) is positive in the interval [-2, 1].

The function f(x) is negative the interval (-∞, -2) U (1, ∞).

The positive regions of a function f(x) are those intervals where the function is above the x-axis. It is where the y-values are positive (not zero).

To find the intervals of x where the function is positive,

In the interval [-2, 1] , the function f(x) is positive.

The negative regions of a function f(x) are those intervals where the function is below the x-axis. It is where the y-values are negative (not zero).

In the interval (-∞,-2) U (1,∞) , the function f(x) is negative.

y-values that are on the x-axis are neither positive nor negative. The x-axis is where y = 0.

when y = 0, x = -2, 1

Therefore, the function f(x) is positive in the interval [-2, 1] and negative in the interval (-∞,-2) U (1,∞).

Answer:

f(x) = (x+5)(x-4)

Step-by-step explanation:

Key skills used in this problem: Quadratic equations, factoring

1) The equation x^2 + x - 20 is factorable (meaning it can be facttored easily)

2) We need to find factors of -20 that add up to 1. This is because our ac (a term times the c term) is -20 and our b term (the coefficient for +x) is 1.

3) The two factors would be 5 and -4.

4) So it would be (x + 5)(x - 4) when factored

Hope you understood and have a nice day!! :D

Answer:

f(x)= (x+5)(x-4)

Step-by-step explanation:

First muliply the coefficient of the xsquared with the constant, in this case 1 × -20 = -20. Then figure out two factors of -20 that equal the coefficient of the stand-alone x when added together. In this case, that coefficient is 1. Factors of -20 that add to 1 are 5 and -4. Now simply take each of those numbers and shove them into parenthesis with an x.

Answer:

  y = 4x +3

Step-by-step explanation:

The slope formula can be used to find the slope:

  m = (y2 -y1)/(x2 -x1)

Using the first two lines of the table, we find the slope to be ...

  m = (11 -7)/(2 -1) = 4/1 = 4

__

The y-intercept can be found from the relation ...

  b = y -mx

Using the slope we found, and the first line of the table, we find the intercept to be ...

  b = 7 -4(1) = 3

__

Then the equation is ...

  y = mx +b . . . . . . slope-intercept form of the equation for a line

  y = 4x +3

Answer: x = 5

Step-by-step explanation:To solve this you first need to collect the like terms 6x-2x=7+3. Add those 4x=20. After that you need to divide both sides. Then you will get you solution.

Answer:

Step-by-step explanation:

6x−13=2x+7

Inverse operation:

6x into a negative then subtract it by 2x

2x - 6x = -4

Change 7 into a negative then subtract it by -13

-13 - 7 = -20

-20 = -4x

Divide:

-20 = -4x

The terms 5c and 12c are like terms. They can both be added.

Step-by-step explanation:

It could be any number the variable has to stay the same and if there is none, it can’t be paired. Also watch out for problems like 12c + 5c^2. THey don’t have the same variable due to th ^2

Given that,

Cost of 6 pounds apples = $4.00

To find,

Unit rate.

Solution,

We have,

6 pounds apples = $4.00

We can find the cost of 1 pound of apples as follows :

1 pound apples =$ (4/6)

= $0.67

So, the cost of 1 pound apples is $0.67.

Step-by-step explanation:

2^400=2^(2×200)

2^(2×200) =[2^(2) ]^200

Now, [2^(2) ]^200=4^200

The power  of 2 in 400! is 397.

Let p is the prime number whose power is to be found

Let n is the factorial number then

p in n! = (n /p) + (n/p²) +(n/p³) + .......

until Numerator < Denominator

and after division only the integer part is taken

Therefore to determine the power of 2 in 400!

2 in 400! = (400 /2) + ( 400 /2²) + (400 /2³) +(400 /2⁴) +(400 /2⁵) +(400 /2⁶) +(400 /2⁷) +(400 /2⁸) + above this N < D

2 in 400! = 200 +100 +50+25+12+6+3+1

2 in 400 = 397

Therefore the power  of 2 in 400! is 397.
