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:

y

We can now combine like terms:

Given the function f(x) = x - 1. evaluate f(-12).
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.Find the range and domain of the following function

PLEASE HELP!!
Pleaaseeeeee
Step-by-step explanation:
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

Answer: (a.) 32x-20 4*8-4*5 (b.) 22y 11y+11y
Step-by-step explanation:
solve the system of equations by the substitution method .
y=5x+8
y=8x+9
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

Graph 4x +3x=11 and x=y+1 as 2 separate lines that intersect.
Answer:
Step-by-step explanation:
So first of all, you can rearrange your equations:
4x + 7x = 11 can be rearranged and simplified to x = 11/7
x = y + 1 can be rearranged to y = x - 1
Then you can graph them like normal by plugging in points. It should look like the following picture

simple common factor problem.
x(x-1)-x^2+2x=5 :))))))
Answer:
[tex]x(x - 1) - {x}^{2} + 2x = 5 \\ {x}^{2} - x - {x}^{2} + 2x = 5 \\ \therefore \: x \: = 5[/tex]
Answer:
x=5
Step-by-step explanation:
[tex]x(x-1)-x^2+2x=5[/tex]
expand by using distributive property
[tex]x^2-x-x^2+2x=5[/tex]
simplify
x=5
check work by substituting 5 into the original equation and simplify
use PEMDAS
[tex]5(5-1)-5^2+2(5)=5[/tex]
[tex]5(4)-25+10=5[/tex]
add and subtract (left to right)
20-25+10=5
5=5
The equation is true, thus x=5
Solve for x. Enter the solutions from least to greatest
5x^2 + 15x – 50 = 0

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)
Answer:
Total Surface Area = 150.72 cmStep-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 = 150.72Anyone know how to do this?

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]2. Now, let's add 24.6 and 38.95 to get how much he earned:
[tex]24.6+38.95[/tex] [tex]63.55[/tex]Therefore, Javier earned 63.55 dollars and cents on those two days.
