PLEASE HELP!!!! Given the equation y = 2x - 8, what is the slope and the y-intercept?

2 answers:

By definition a line of the form y=mx+b tells you that the slope is m and the y-intercept is b, so by inspection, m=2 and b=-8

Y=mx+b
so m=2 and b=-8

John buys 1.5 pounds of Skittles, 4.5 pounds of Reese's, and 2.3 pounds of chips. If the candy cost $0.70 a pound and the chips

jeka57 [31]

Answer:

Total amount spend = $6.96

Step-by-step explanation:

Given:

Amount of Skittles = 1.5 pound

Amount of Reese = 4.5 pound

Amount of chips = 2.3 pound

Candy cost = $0.70 per pound

Chips cost = $1.20 per pound

Find:

Total amount spend

Computation:

Total amount spend = [Amount of Skittles+Amount of Reese][Candy cost]+[Amount of chips][Chips cost]

Total amount spend = [1.5+4.5][0.70]+[2.3][1.20]

Total amount spend = 4.2 + 2.76

Total amount spend = $6.96

Write the quadratic equation whose roots are 4 and 5, and whose leading coefficient is 4.

Umnica [9.8K]

Answer:

Answer: 4x² - 9x + 20 

Step-by-step explanation:

• General quadratic equation:

${ \rm{ {x}^{2} - (sum \: of \: roots)x + (product \: of \: roots) }}$

• sum of roots → 4 + 5 = 9

• product of roots → 4 × 5 = 20

• substitute:

${ \boxed{ \rm{4 {x}^{2} - 9x + 20 }}}$

What is the sum of the first 10 terms of the geometric sequence 4, -12, 36, -144

Oksanka [162]

The sum of the first 10 terms of the sequence 4, -12, 36, -144 is -59058

The given geometric sequence is:

4, -12, 36, -144

The first term, a = 4

The common ratio,

$r = \frac{-12}{4}\\r = -3$

Since we are looking for the sum of the first 10 terms

The number of terms, n = 10

The sum of the first n terms of a geometric sequence is given as:

$S_n = \frac{a(1-r^n)}{1-r} \\S_n = \frac{4(1-(-3)^{10}}{1-(-3)} \\S_n = \frac{4(1-59049)}{4} \\S_n = -59048$

The sum of the first 10 terms of the sequence 4, -12, 36, -144 is -59058
