use the function g=f+4 to find the value of g when f=1use the function u=10c to find the value of u when c=5how about this one u

NeTakaya

Given function g=f+4

To find the value of g at f=1

substitute f=1 in the given equation

$\begin{gathered} g=f+4 \\ g=1+4 \\ g=5 \end{gathered}$

So, at f=1, the value of g will be 5.

(b).

At u=10c

to find the value of u at c=5

substitute the value c=5 in the given equation

$\begin{gathered} u=10c \\ u=10\times5 \\ u=50 \end{gathered}$

The value of u at c=5 is 50

(c).

Given function u=n-5

to find the value of u at n=7

substitute the value of n=7 in the given equation

$\begin{gathered} u=n-5 \\ u=7-5 \\ u=2 \end{gathered}$

So the value of u at n=7 is 2

(d).

Given function h=g+13

to find the value of h at g=1

substitute the value g=1 in the given equation

$\begin{gathered} h=g+13 \\ h=1+13 \\ h=14 \end{gathered}$

The value of h at g=1 is 14

(e).

Given function w=14f

to find the value of w at f=4

substitute the value f=4 in the given equation

$\begin{gathered} w=14f \\ w=14\times4 \\ w=56 \end{gathered}$

The value of w at f=4 is 56

Solve by the linear combination method (with or without multiplication). x + y = 40 0.08x + 0.03y = 1.7

Neporo4naja [7]

That's also known as the addition method.
x + y = 40
.08x+.03y=1.7
We need to multiply the top equation by either a -.08 or a -.03 to eliminate one of the variables. Let's get rid of the y:
-.03(x + y) = -.03(40) which gives us

-.03x - .03y = -1.2
.08x + .03y = 1.7
When we add those together we are left with .05x = .5 and x = 10. If we sub that 10 in for x into the first equation (either would have worked but the first one is way easier to work with!) we get 10 + y = 40 and y = 30. So the solution to the system is (10, 30)

At a fabric store, fabrics are sold by the yard. A dressmaker spent $36.35 on 4.25 yards of silk and cotton fabrics for a dress.

rewona [7]

Answer:

Answer:

Silk = x = 1.5 yards

Cotton = y = 2.75 yards

Step-by-step explanation:

x + y = 4.25

16.90x + 4y = 36.35

1. The solution to the equation represent number of yards of silk and number of yards of cotton bought.

x + y = 4.25 (1)

16.90x + 4y = 36.35 (2)

Multiply (1) by 4

4x + 4y = 17 (3)

16.90x + 4y = 36.35 (2)

Subtract (3) from (2)

16.90x - 4x = 36.35 - 17

12.90x = 19.35

Divide both sides by 12.90

x = 19.35 / 12.90

= 1.5

x = 1.5 yards

Substitute x = 1.5 yards into (1)

x + y = 4.25

1.5 + y = 4.25

y = 4.25 - 1.5

= 2.75

y = 2.75 yards

Silk = x = 1.5 yards

Cotton = y = 2.75 yards
