Answer:
Two or more Algebraic expressions are said to be equivalent, if both the expression produces same numerical value , when variable in the expressions are replaced by any Real number.
The two expressions are
1. 7 x +4
2. 3 x +5 +4 x =1
Adding and subtracting Variables and constants
→7 x +5=1
→7 x +5-1
→7 x +4
→ When x=2,
7 x + 4 =7×2+4
=14 +4
=18
So, Both the expression has same value =18.
→So, by the definition of equivalent expression, when ,you substitute , x by any real number the two expression are equivalent.
Correct options among the given statement about the expressions are:
1.When x = 2, both expressions have a value of 18.
2.The expressions have equivalent values for any value of x.
3.The expressions have equivalent values if x = 8.

(X-7)(3x+2) need answer!!
Answer: the answer is
=3[tex]x^{2}[/tex]−19x−14
Step-by-step explanation: (x−7)(3x+2)
=(x+−7)(3x+2)
=(x)(3x)+(x)(2)+(−7)(3x)+(−7)(2)
=3x2+2x−21x−14
=3x2−19x−14
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.

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).

Thank neeed help thanks
Answer:
72 degrees
Step-by-step explanation:
hi! the total angle measure of a triangle is 180 degrees. so, all three angle measures must add up to 180.
6x+6x+8x=180
20x=180
x=9
now, plug in x=9 for angle ABC.
8(9)= 72
m<ABC= 72 degrees

i just want to see if i got the correct answer my answer was
b=-15
Answer:
yes, the answer is b = -15
Step-by-step explanation:
3(-15) = -45
-45 + 9 = -36
-36 - 16 = -52
so b = -15
How do I write an equation in point-slope form for m=-3 (-2,-1) ?
Answer:
y + 1 = -3(x + 2)
Step-by-step explanation:
Point-slope form is y - y1 = m(x - x1)
m= -3 (-2, -1)
Plug -3 in for the m in the equation, -2 in for x1, and -1 in for y1
y - (-1) = -3(x - (-2))
Subtracting negatives will make them positive
y + 1 = -3(x + 2)
This is the point-slope form, continuing to solve for y will give the y-intercept form.
Y-intercept Form:
y = -3x - 7
Directions: Multiply, divide, and simplify the following exponential expressions.

Find the equation of the line shown.
Given : A graph of linear equationis given to us.
To Find : The equation of the line .
Solution : Here we can see that the line passes through points ( 1 , 2 ) and ( 2 , 4). So , clearly here we can use Two - point form to find the equation of the line .
So , first point will be , ( 1 , 2 ) & second point will be ( 2 , 4 ) . So here ;
[tex]\sf x_1 = 1\: \& \:y_1 = 2[/tex][tex]\sf x_2 = 2\: \&\: y_2=4[/tex]Now , the two point form formula is :
[tex]\Large\boxed{\red{\sf \purple{\mapsto} y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)}}[/tex]
[tex]\tt:\implies y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1) [/tex]
[tex]\tt:\implies y-2=\dfrac{4-2}{2-1}(x-1) [/tex]
[tex]\tt:\implies y-2 = \dfrac{2}{1}(x-1) [/tex]
[tex]\tt:\implies y-2=2(x-1)[/tex]
[tex]\tt:\implies y -2 = 2x - 2 [/tex]
