write the function in standard form y=-(x+3)(x+7)​

Answers

Answer 1

To write this in standard form we need to multiply the two terms in parenthesis on the right side of the equation.

To multiply these two terms you multiply each individual term in the left parenthesis by each individual term in the right parenthesis.

y

=

becomes:

We can now combine like terms:

y

63+36+X = 180 (interior angles of a triangle equal 180)

X = 180-99

X= 81

X+Z= 180(angles on a straight line adds up to 180)

81+y= 180

Z=180-81

Z =99

13+Z+Y=180

13+99+Y=180

Y=180-112

Y=68

1. Given that Javier's pay rate is $10.25 per hour, let's find the combined amount he earned from Monday and Tuesday by multiplying the hours worked by 10.25.

[tex]2.4 * 10.25[/tex]  [tex]24.6[/tex] [tex]3.8*10.25[/tex] [tex]38.95[/tex]

Answer: part A because f(x)=(2x-1) (2x+3)

solve the system of equations by the substitution method .
y=5x+8
y=8x+9

Answers

Answer:

rearrange the question

y - 5x = 8.................(1)

y - 8x = 9..................(2)

make y the subject formula in eqn. (1)

y = 8 + 5x................(3)

substitute

8 + 5x - 8x = 9

-3x = 1

x = -⅓

y = 8 + 5x

y = 8 + (-⅓)

y = 23/3

Given the function f(x) = x - 1. evaluate f(-12).

Answers

Answer:

f(-12) = -13

Step-by-step explanation:

f(x) = x - 1

Let x = -12

f(-12) = -12-1

       = -13

Answer:

[tex]f(x) = x - 1 \\ f( - 12) = - 12 - 1 \\ \boxed{ f( - 12) = - 13}[/tex]

f(-12) = -13 is the right answer.

The shape of a glass stopper is composed of a hemisphere of radius 3 cm and a right circular cone with a slant height of 5 cm as shown. Find the total surface area of the glass stopper. (Take 3.14) ​

Answers

Answer:

Total Surface Area = 150.72 cm

Step-by-step explanation:

Surface Area of a cylinder = 2 × area of base + lateral face

First find the area of the base

Area of Base = πr² ( pi × radius squared ) ( pi = 3.14 )

AB = 3.14 × 3²

AB = 3.14 × 9

Area of Base = 28.26

Next, find the lateral face

Lateral Face = circumference of base × altitude

( circumference of base = 2πr ) ( altitude = height of the cylinder )

LF = 2 × 3.14 × 3

Lateral Face = 18.84

Last, is the Surface Area

Surface Area of a cylinder = 2 × area of base + lateral face (formula)

SA = 2 × 28.26 + 18.84 × 5

SA = 56.52 + 18.84 × 5

SA = 56.52 + 94.2

Total Surface Area = 150.72

Julie ran 7/8 of a mile. Kelly ran 1/3 of a mile.. How much farther did Julie run?

Answers

First convert the distance she ran from a mixed number to a improper fraction:

2-3/4 equals 11/4.

Since this a unit rate problem divide the miles by the time traveled.

11/4 (miles) ÷ 1/3 (hour). When you divide a number by a fraction use (Keep-Change-Flip).

11/4 × 3/1 = 33/4 miles/hour.

Convert improper fraction to mixed number by dividing 33 by 4.

33/4 = 8-1/4 miles/ hour.
