1) Create was we already know in the equation. 16=-7(-3)+b. (This is using the initial equation of y=mx+b.)

2) Simplify and solve for b: 16=21+b = -5=b

3) Replug your be value into your equation: y=-7x-5.

Answer

y=-7x-5

Words: y equals negative seven x, minus five.

18. 0.796 + 13 = 13.796 (the 13 is a whole number, so just put it in front of the decimal)

19. 15.63 + 24.36 = 39.99 (1+2=3 ; 5+4=9 ; 6+3=9 ; 3+6=9)

20. 19.86 - 4.94 = 14.92

21. 82 - 67.18 = 15.18 (again, whole number, there's no decimals to subtract, so leave them be)

22. 14.39 - 12.16 = 2.23 (1-1=0 ; 4-2=2 ; 3-1=2 ; 9-6=3)

Express the ratio in the simplest form. 20 gallons to 0.75 gallons
expeople1 [14]

ANSWER

The ratio in the simplified form is

80:3

EXPLANATION

We want to express 20 gallons to 0.75 gallons as a ratio in its simplest form.

We obtain the ratio as follows:

20:0.75

This is the same as

20: \frac{3}{4}

We multiply each term in the ratio by 4 to obtain;

20 \times 4:0.75 \times 4

This gives us,

80:3

Exponential Growth and Decay The expressions below represent either exponential growth or exponential decay. Check all the expre
Tomtit [17]

Answer:

First one: 5x3(0.75)2t

and fourth one: 0.05x500(0.005)t

Step-by-step explanation:

In order to have an exponencial decay, the rate of the exponencial function needs to be lesser than 1.

The rate is the value between parenthesis, so in the first equation, the rate is 0.75, so this is an exponencial decay.

The second equation has rate = 2.4, so this is not an exponencial decay.

The third equation has rate = 1.04, so this is not an exponencial decay.

The fourth equation has rate = 0.005, so this is an exponencial decay.
