Answer:
y = 2x + 4
Step-by-step explanation:
y2 - y1/ x2- x1
= 8 - 6 / 2 - 1
= 2
So now our equation is y = 2x + b (from y = mx+b). Now plug in the coordinates to find the y-intercept.
y = 2x + b
8 = 2(2) + b
8 = 4 + b
4 = b
The y-intercept is 4.
If we put one of the values like the x in the equation, we should get the y value.
y = 2x + 4
y = 2 (3) + 4
y = 6 + 4
y = 10

Trevor stated that (4,0) is the solution to the system of equations. Joey stated that (0, -2) is the solution to the system of equations. Which
conclusion is true?
Answer:
Trevor is right
Step-by-step explanation:
The solution of system of equations are [tex](4,0)[/tex]
Therefore, Trevor conclusion is true.
System of equations:Given system of equations;
[tex]x- 2y = 4\\\\y=4-x[/tex]
Substitute value of y from equation (2) in equation (1).
[tex]x-2(4-x)=4\\\\x-8+2x=4\\\\3x=12\\\\\\x=12/3=4[/tex]
Substitute value of x in second equation.

Solve for the variable "x" in this example
Answer:
x=9
Step-by-step explanation:
these are vertical angles, so they equal eachother!
12x-3=105
move three to the other side of the equals sign
12x=108
divide both sides by 108
x=9
Answer: x=9
Step-by-step explanation:
These angles are equal, so you can set 105 equal to 12x-3. Add 3 and divide by 12 to get x=9.
what is the surface area
Answer:
The surface area of the rectangular prism is 748 ft2.
Step-by-step explanation:
formula for surface area: A=2(wl+hl+hw)
A=2(wl+hl+hw)=2(5x16+14x16+14x5)=748
Answer:
748 ft²
Step-by-step explanation:
For the surface area, you need to add up the area of all sides, six in this example, but it can be simplified into three by multiplying some of them by two as its presumed a rectangle
x1 = 5*14*2 = 140
x2 = 16*14*2 = 448
x3 =16*5*2 = 160
You find the sum of these; 140 + 160 + 448 = 300 + 448 = 748

Answer:
im not sure but i think its e,c,f
Step-by-step explanation:
Answer:
55 °
Here's the way i got my answer :
Complementary angles are two angles that have a sum of 90° ,therefore 35° + X = 90°
X=55° .
to get ∠DBF
180° - 90° = 90 °
to get ∠EBF
∠CBD + ∠DBE + ∠EBF = 180°
35° + 90° + ∠EBF = 180°
∠EBF = 55°

Easy brainly!!! Please Help!!
Answer:
64
Step-by-step explanation:
Given :
h α 1 / sqrtk
h = k/sqrt(d)
Obtain the value of k, when. d = 4 and h = 20
20 = k / sqrt(4)
20 = k / 2
20 * 2 = k
k = 40
Therefore, the value of d when h = 5
h = k/sqrt(d)
5 = 40 / sqrt(d)
Square both sides
25 = 1600/d
25d = 1600
d = 1600 / 25
d = 64
d = 64

7(x+4)=-21
what does x equals
CORRECT answers ONLY please
Answer: x = -7
Step-by-step explanation:
7 (x + 4) = -21
7x + 28 = -21
Subtract 28 from both sides
7x = -49
Divide both sides by 7
x = -7
Answer:
x = -7
Step-by-step explanation:
first distribute he 7 to get 7x + 28 = -21
then subtract 28 from both sides to get 7x = -49
lastly divide 7 from both sides to get x = -7

2x+4y is the equivalent expression of x+x+4y.
What is Expression?An expression is combination of variables, numbers and operators.
The given expression is x + x + 4y
x plus x plus four times of y.
In the given expression x and y are two variables.
Equivalent expressions are expressions whose value will remain same after simplifying or solving.
We need to add x variable terms once and then with y term
x + x + 4y
2x+4y
Hence, 2x+4y is the equivalent expression of x+x+4y.
