It is required to find the solution.

A function is defined as a relation between a set of inputs having one output each. function is a relationship between inputs where each input is related to exactly one output. Every function has a domain and codomain or range. A function is generally denoted by f(x) where x is the input.

Given:

The given function is

f(x) = 3x + 4

Put the value of x= 2 in the function we get,

f(2)=3(2)+4

f(2) = 6+4

f(2) = 10

Step-by-step explanation:

Answer:

the amount of interest = 405 000

the amount she has to pay  = 405 000 + 180000 = 585 000

Step-by-step explanation:

We make use the simple interest formula

PRT/100

P is the principle

R is the rate

T is the time

180 000 * 7.5 * 30

= 40 500 000 / 100

= 405 000

the amount of interest = 405 000

the amount she has to pay  = 405 000 + 180000 = 585 000

Answer:

see below

Step-by-step explanation:

bh + hr = 25

Factor out an h

h( b+r) = 25

Divide each side by ( b+r)

h( b+r)/( b+r) = 25/( b+r)

h = 25/( b+r)

Now solve for r

bh + hr = 25

Subtract bh from each side

bh -bh+ hr = 25-bh

hr = 25 -bh

Divide by h

hr/h = 25/h -bh/h

r = 25/h -b

Perimeter is

P = 2(l+w), where l= length, w = width

Substitute values to find the value of w:

Then

Dimensions are 14 ft and 30 ft

Answer:

Perimeter is the sum of all sides added together.

Variables:

P=88

L=W+16

W=?

Equation:

88=2*(W+16+W)

Write with units:

L=30 ft.

W= 14ft.

Step-by-step explanation:

88=2*(W+16+W)

divide both sides by 2

44=W+16+W (This is one width and one length)

combine like terms

44=2W+16

subtract 16 from both sides

28=2W

divide both sides by 2

14=W

Your width is 14

Your length is 16 more than your width.

14+16=L

30=L

Step-by-step explanation:

Points are (8,5) and (-12,-9)

The equation of a line passing through two points is given by :

[tex]y-y_1=m(x-x_1)\ \text{m is slope}\\\\y-5=\dfrac{y_2-y_1}{x_2-x_1}(x-8)\\\\y-5=\dfrac{-9-5}{-12-8}\times (x-8)\\\\y-5=\dfrac{7}{10}\times (x-8)\\\\10y-50=7x-56[/tex]

or

[tex]-50+56=7x-10y\\\\7x-10y=6[/tex]

But he writes the equation 7x – 10y = 3 which is not matching with the one we have calculated. It means that model calculated by Devon is not good.

Answer:

If the model is good, then both points will check in the equation. Substituting 8 for x and 5 for y in the equation results in 56 – 50 = 3, which is not true. Therefore, the model is not good. Using (–12, –9) as a check results in –84 + 90 = 3. The constant value in the equation should be 6, not 3. In slope-intercept form, the y-intercept should be –3/5.

Answer:

he rode the roller coaster 4 times the bumper cars 3 times and the water slide 4 hoped i helped

Step-by-step explanation:

The question is an illustration of a system of simultaneous equation

He rode the roller coaster 5 times; bumper cars 1 time and water slides 4 times.

Let:

[tex]b \to[/tex] bumper cars

[tex]r \to[/tex] roller coaster

[tex]w \to[/tex] water slides

He rode 10 total rides.

So:

[tex]b + r + w = 10[/tex]

The equation for the times he waited is:

[tex]r + \frac{20}{60}b + \frac{15}{60}w = 6\frac{20}{60}[/tex]

Simplify fraction

[tex]r + \frac b3 + \frac w4 = 6\frac 13[/tex]

The proportion of rides is:

[tex]r =b + w[/tex]

Substitute [tex]r =b + w[/tex] in [tex]b + r + w = 10[/tex] and [tex]r + \frac b3 + \frac w4 = 6\frac 13[/tex]

[tex]b + b + w + w = 10[/tex]

[tex]2b + 2w = 10[/tex]

Divide through by 2

[tex]b + w = 5[/tex]

Similarly

[tex]r + \frac b3 + \frac w4 = 6\frac 13[/tex]

[tex]b + w + \frac b3 + \frac w4 = \frac{19}3[/tex]

Multiply through by 12

[tex]12b + 12w + 4b + 3w = 4 \times 19[/tex]

[tex]16b + 15w = 76[/tex]

Make b the subject in [tex]b + w = 5[/tex]

[tex]b = 5 -w[/tex]

Substitute [tex]b = 5 -w \\[/tex] in [tex]16b + 15w = 76[/tex]

[tex]16(5 -w) + 15w = 76[/tex]

[tex]80 -16w + 15w = 76[/tex]

Collect like terms

[tex]-w = 76 - 80[/tex]

[tex]-w = -4[/tex]

[tex]w = 4[/tex]

Recall that:

[tex]b = 5 -w[/tex]

[tex]b = 5 - 1[/tex]

[tex]b =4[/tex]

Recall that:

[tex]r =b + w[/tex]

[tex]r = 1 + 4[/tex]

[tex]r = 5[/tex]

Hence, he rode the roller coaster 5 times; bumper cars 1 time and water slides 4 times.
