Answer:
4(x + 1)= -3x - 10
on the bracket 4( x +1)
4x + 4 = -3x - 10
collect like terms
4x + 3x = -10 - 4
7x = -14
divide both sides by 7
x = -2
Please help me I am so confused it would mean a lot.
Step-by-step explanation:
1. The midpoint formula says the coordinates of the midpoint are the average of the endpoints.
x = (x₁ + x₂) / 2
y = (y₁ + y₂) / 2
I'll do #2 and #3 as examples.
2. x = (-4 + 10) / 2 = 3
y = (6 + -10) / 2 = -2
So the midpoint is (3, -2).
3. x = (-3 + -6.5) / 2 = -4.75
y = (-8 + -4.5) / 2 = -6.25
So the midpoint is (-4.75, -6.25).

I HOPE THIS HELPED!En la casa de Juan, van a pedir pizza para la comida, pero cuando la van a pedir se dan cuenta que deben pedirla por perímetro o área de la misma. La mamá dice que es más grande la de perímetro de 100cm y el papá dice que es más la de área de 100cm². ¿Cuál tiene la razón? *
Responder:
La pizza con un perímetro de 100 cm es más grande ¿verdad?
Explicación paso a paso:
Deja que la pizza tenga forma circular.
Sea el área de la pizza = πd² / 4 y;
Perímetro de la pizza = πd
d es el diámetro de la pizza
Si la madre dice que el que tiene un perímetro de 100 cm es más grande, para estar seguros necesitamos obtener el diámetro de la pizza. La de mayor diámetro será la pizza más grande.
P = 100cm
100 = πd
d = 100 / π
d = 100 / 3,14
d = 31,85 cm
El diámetro de la pizza mamá es de 31,85 cm.
Si el padre dice que el que tiene un área de 100 cm² es más grande, obtengamos también el diámetro para estar seguros.
A = πd² / 4
100 = πd² / 4
400 = πd²
d² = 400 / π
d² = 400 / 3,14
d² = 127,39
d = √127,39
d = 11,29 cm
Por lo tanto, el diámetro de la pizza padre es de 11,29 cm.
Dado que el diámetro de la pizza madre es mayor que el de esa, la pizza con un perímetro de 100 cm es más grande, lo que demuestra que la madre tiene razón.
identify terms, like terms, coefficients, constant terms then simplify the expression
Answer:
coefficient: a numerical or constant Quanity plays before and multiplying the variable in and algebraic
constant turn: a constant is it's only number or sometimes a letter such as a, b, or c
like terms: our terms food variables and their exponents such as two X over two, (are the same).

What is the inverse of the function f(x)=1/9x+2
Answer:
f ^− 1 ( x ) = 9 x − 18
Step-by-step explanation:
To find the inverse, interchange the variables and solve for y .
Answer:
Add x x and 0 0 . Since g(f(x))=x g ( f ( x ) ) = x , f−1(x)=9x−18 f - 1 ( x ) = 9 x - 18 is the inverse of f(x)=19x+2 f ( x ) = 1 9 x + 2
Step-by-step explanation:
DESCRIBE how a power with a zero exponent (a^0) and a power with a negative exponent (a^−n) can be simplified.
Answer:
[tex]a^{-n}[/tex] is [tex](\frac{1}{a})^{n}[/tex] OR [tex]\frac{1}{a^{n} }[/tex]
[tex]a^{0}[/tex] = 1, where a ≠ 0
Step-by-step explanation:
To simplify the exponents, you must put it in positive value
Example:
The simplest form of [tex]2^{-3}[/tex] is to change the exponent from negative value to positive value.
You can do that by reciprocal the number, [tex]2^{-3}=(\frac{1}{2})^{3}[/tex]You can write it [tex]\frac{1}{2^{3}}[/tex], because 1 to any power equal 1That means if you want to simplify [tex]a^{-n}[/tex], reciprocal a and change the sign of the power from -n to n
The simplest form of [tex]a^{-n}[/tex] is [tex](\frac{1}{a})^{n}[/tex] OR [tex]\frac{1}{a^{n} }[/tex]
For any number, a (a ≠ 0), 1 × a = a, so, the reason that any number to the zero power is 1 because any number to the zero power is just the product of no numbers at all, which is the multiplicative identity, (1)
Example:
The value of [tex](5)^{0}[/tex] = 1, because it is the product of no numbers, so it is equal to the multiplicative identity (1)
That means [tex]a^{0}[/tex] = 1, where a ≠ 0
Very important note:
[tex](0)^{0}[/tex] is undefined value
Michael is saving to buy a car. He has 1/4 what he needs to buy the car. His savings account has a balance of $1000. How much more does he need to save?
Answer:
3000
Step-by-step explanation:
If you take the amount he already has (1000) and multiply by the reciprocal (4) you'll get $4000, the amount that the car costs. From there subtract the amount he already has (1000) and you get the amount he still needs (3000).

What values of a and b make this equation true?
(4 + ✓–49) – 2(/(-4)2 + V–324) = a + bi
Answer:
-4 , -29
Step-by-step explanation:
The values of a and b that make the equation true are -28 and -9, respectively
How to determine the true values of a and b?The equation is given as:
(4 + √-49) – 2((-4)² + √–324) = a + bi
Evaluate the exponents
(4 + 7i) – 2(16 + 18i) = a + bi
Expand the bracket
4 + 7i – 32 - 16i = a + bi
Collect like terms
4 – 32 + 7i - 16i = a + bi
Evaluate like terms
-28 -9i = a + bi
By comparison, we have:
a = -28 and b = -9
Hence, the values of a and b that make the equation true are -28 and -9, respectively

Find the measure of angle 6.
Answer:
6=72
Step-by-step explanation:
if 1 had the number 108 2 would be 72 because both have to equal 180 also say 3 is right under 1 also on the same line it would be also 72 and 4 also on the same line would be 72 .
5 on a different line would be 108 and 6 on the same line as number 5 would be 72 also 7 would be 108 and 8 would be 82
8 would be 72 not 82

Jack and Sara went out to lunch. They spent $28.72 on
their meal. Jack and Sara wanted to leave the waitress a
15% tip. What is the final cost?
Tip = $28.72 x 15% = $4.308
=> Final cost = $28.72 + $4.308 = $33.208
Answer:
33.03
Step-by-step explanation:
you multiply 28.72 by 15%or (.15) you will get 4.308, then you add 4.308 and 28.72 and you will get 33.028 then you round it up and get 33.03
Karen is saving money to buy a game . So far he saved $15 , which is three fourths . How much does the game cost ?
Answer:
$25
Step-by-step explanation:
Let X = total cost of game
(3/5) X = $15
Multiply both sides of equation by 5/3
(5/3)(3/5) X = (5/3) $15
X = $25
cost of game is $25
