All exponential functions have the y-intercept (0,1):

e^(0) = 1

10^0= 1

and so on.

Y intercept of a function can be obtained by evaluating the value of the function when x=0, i.e.

y-intercept of f(x) = f(0)

Here, f(x) = 4^(x)

so y-intercept = f(0) = 4^0 = 1

X+4y=30 system by substitution <br><br> X-2y=0

Dmitry [639]

Answer:

x=10, y=5

Step-by-step explanation:

For substitution, you always want to get the variable alone. The second equation (x-2y=0) will be easier to substitute into the first equation.

x-2y=0

x=2y

You can substitute 2y as x on the first equation (x+4y=30).

2y+4y=30

6y=30

y=5

Plug y=5 into any equation.

x+4(5)=30

x+20=30

x=10

A party mix is made by adding nuts that sell for $2.50 per kg to a cereal mixture that sells for $1 per kg. How much of each sho

sesenic [268]

Answer:

The amount of nuts is 16 kg and cereal mixture is 44 kg to obtain 60 kg of a mix that will sell for $1.40 per kg

Step-by-step explanation:

Let

x=nuts at $2.50 per kg

y=cereal at $1 per kg

x+y=60 kg (1)

2.50x+y=1.40(60) (2)

From (1)

x=60-y

Substitute x=60-y into (2)

2.50x+y=1.40(60)

2.50(60-y)+y=84

150-2.5y+y=84

-1.5y=84-150

-1.5y=-66

Divide both sides by -1.5

y=44 kg

Substitute y=44 into (1)

x+y=60

x+44=60

x=60-44

=16

x=16 kg
