Answer:

The slope m is 1.9 and the y-intercept b is 2.5.

Step-by-step explanation:

This is in slope-intercept form, y=mx+b, where m is slope and b is the y-intercept.

y = 1.9x + 2.5 means that m is 1.9 and b is 2.5.

Write an equation for the nth term of the arithmetic sequence. Then find a50. 8, 2, -4, - 10,

AlexFokin [52]

Answer: See below

Explanation:

Write an equation for nth term:

a + d(n - 1)

a = 8 (first term)
d = -6 (common difference)

8 - 6(n - 1)
= 8 - 6n + 6
= -6n + 14

Find a 50:

-6(50) + 14
= -300 + 14
= -286

Keith drove 436 miles using 16 gallons of gas at this rate how many miles would he drive using 14 gallons of gas

KengaRu [80]

This Question is related to Direct Proportionality

Here : The Number of Miles Driven is Directly Proportional to Number of Gallons of Gas

Number of Miles ∝ Gallons of Gas

Given Keith with 16 Gallons of Gas Drove 436 Miles

⇒ Keith with 1 Gallon of Gas would Drive - $\frac{436}{16}$ Miles

⇒ Keith with 1 Gallon of Gas would Drive : 27.25 Miles

⇒ Keith with 14 Gallons of Gas would Drive : 14 × 27.25 Miles

⇒ Keith with 14 Gallons of Gas would Drive : 381.5 Miles

Write a quartic trinomial with a leading coefficient of 2 using standard form

lions [1.4K]

Quartic => polynolial degree 4, i.e. the highest exponent of the variable is 4

trinomial=> three terms

leading coefficient = the coefficient in front of the term with the highest exponent.

standard form=> ax^4 + bx^3 + c^2 + dx + e

Solution:

2x^4 + x^3 + 0x^2 + 0x + 30

which is equal to 2x^4 + x^3 + 30: this is a quartic trinomial with leading coefficient 2, written in standard form.
