Answer:

$1000 ; 500 ; 1000 ; y = 500x + 1000

Step-by-step explanation:

From the graph, the initial deposit which started the savings account is $1000 ; this is the value on the y - intercept, the value in the account at time or period = 0.

The slope :

x1 = 0 ; y1 = 1000

x2 = 6 ; y2 = 4000

Slope = Rise / Run

Rise = y2 - y1 = 4000 - 1000 = 3000

Run = x2 - x1 = 6 - 0 = 6

Hence,

Slope = 3000 / 6

Slope = 500

y - intercept = 1000 (from. Graph)

Equation in slope intercept form:

General form : y = mx + c

m = slope ; c = intercept

Equation is written as ;

y = 500x + 1000

Answer: a = -4

Step-by-step explanation: Function Composition is when two functions f(x) and g(x) result in another function h(x), such that h(x) = f(g(x)). In other words, put the result of one function into the other one.

In this situation,

h(x) = f(g(x))

which means

h(x) = f(x³+a)

h(x) = [tex]\sqrt{x^{3}+a+2}[/tex]

[tex]\sqrt{x^{3}-2} =\sqrt{x^{3}+a+2}[/tex]

Now, to find a, we separate equal terms:

1) Both are squared, so we can "eliminate" the square;

2) x³ = x³;

3) [tex]-2=a+2[/tex]

[tex]a=-4[/tex]

For function composition h(x) = f(g(x)), the value of a is -4.

Hello! (:

y=2x-5

This equation is written in slope-intercept form (y=mx+b)

Where

m is the slope of the line (2)

b is the y-intercept (5)

Hope it helps! Please ask if you have any query.

The slope of the line y = 2x + 5 is 2 obtained by comparing it with slope intercept form y=mx+b, where m is slope.

The slope represents the rate at which the line is increasing or decreasing as you move along the x-axis.

The slope of a linear equation in the form y = mx + b is represented by "m."

In this case, "m" is 2, which means the slope of the line y = 2x + 5 is 2.

Since the slope is positive (2), it means that as x increases by 1 unit, y increases by 2 units, and as x decreases by 1 unit, y decreases by 2 units.

The slope of 2 indicates that the line is inclined, and it rises at a steady rate of 2 units for every 1 unit moved to the right along the x-axis.

Hence, slope of the line  y = 2x + 5 is 2.

Answer: 32

Step-by-step explanation:

Total number of students = 452

Students in favor of banning guns = 67%

Students against banning guns = 26%

Students who didn't voice their opinions = 100% - (67% + 26%) = 100% - 93% = 7%

The number of students who didn't voice their opinions would be:

= 7% × 452

= 0.07 × 452

= 31.64

= 32 to nearest whole number

Answer:

8.3%

Step-by-step explanation:

The formula for Percentage error is given as:

|Measured value - True value|/True value × 100

The measured value = 13cm

The true value = 12cm

Hence:

Percentage error = |13 cm - 12cm|/12 cm × 100

= 1/12 × 100

= 8.3%

The percent error of Jessica's measurement is 8.3%

Answer:

Basic parabola:  y = ax2 + bx + c

We have 3 points we can plug in for (x, y) to create 3 simultaneous equations

(-2, 24):  24 = 4a - 2b + c   {equation 1}

(3, -1):   -1 = 9a + 3b + c    {equation 2}

(-1, 15): 15 = a - b + c        {equation 3}

Solve this system to find the values of a, b, c

Let's first eliminate variable c:

4a - 2b + c = 24   {equation 1}

 a -  b + c = 15    {equation 3}

---------------------  subtract

3a - b = 9

9a + 3b + c = -1    {equation 2}

 a -  b + c = 15    {equation 3}

--------------------  subtract

8a + 4b = -16

We now have two equations with 2 unknowns we can use to find a, b

3a - b = 9         {equation 4}

8a + 4b = -16   {equation 5}

Multiply equation 4 through by 4 and add equations

12a - 4b = 36

8a + 4b = -6

-----------------   add

20a = 30

a = 30/20

a = 3/2

8a + 4b = -6

8(3/2) + 4b = -6

12 + 4b = -6

4b = -6- 12

4b = -18

b = -18/4

b = -9/2

Plug these 2 values into one of the original equations and solve for c

15 = a - b + c        {equation 3}

15 = 3/2 + 9/2 + c

15 = 12/2 + c

15 = 6 + c

c = 15-6

c = 9

y = (3/2)x2 - (9/2)x+ 9

Step-by-step explanation:

Answer:

% Apple juice = [tex]\frac{4}{7}[/tex] × Y × 100.

Step-by-step explanation:

Given:

Ratio of apple juice to water = 4 : 3 = Y i.e 4+ 3 = 7

To find the exact % of apple juice used in  recipe, we use the ratio of juice to water provided, given Y as any amount of apple cider.

∴ equation [tex]\frac{4}{7}[/tex] × Y = amount of apple juice.

for percentage, [tex]\frac{4}{7}[/tex] × Y × 100 = amount of apple juice.

Proof:

In 200ml apple cider, amount of apple juice present

= 4/7 × 200 = 114.2ml of juice

To make upto 00ml cider, add (200-114.2)ml of water.

HJ + JM = 5

Step-by-step explanation:

The number line is majorly used to show the positions of directed numbers. For the given question, the number line has the required points as shown in the attachment to this answer.

From the number line,

HJ = -1 - (-3)

    = -1 + 3

    = 2

HJ = -2

JM = 2 - (-1)

     = 2 + 1

     = 3

Thus,

HJ + JM = 2 + 3

              = 5

HJ + JM = 5

Answer:

1280

Step-by-step explanation:

The first 3 part of the ratio corresponds to 960 bottles of orange juice

Dividing 960 by 3 gives the value of one part of the ratio.

960 ÷ 3 = 320 ← value of 1 part of the ratio, then

apple juice = 4 × 320 = 1280 bottles
