Answer:
x = 5 AB = 6 AC = 7Step-by-step explanation:
Points A, B, and C are collinear and point B is between A and C then
AB + BC = AC
2x - 4 + 1 = x + 2
2x - 3 = x + 2
+3 +3
2x = x + 5
-x -x
x = 5
AB = 2x - 4 = 2×5 - 4 = 10 - 4 = 6
AC = AB +BC = 6 + 1 = 7

Which set of ordered pairs represents a function?
O {(-4,9), (-4,7), (1, -5), (7, -8)}
{(-5, -5), (-9,1), (8,-6), (-9,-4)}
{(-6, -6), (-2,-2), (7,-6),(-5,0)}
{(-7, -9), (-7, -7), (3,-7), (5,-5)}
Submit Answer
Answer: {(-6, -6), (-2,-2), (7,-6),(-5,0)}
Step-by-step explanation:
To find the ordered pairs that represent a function, we want to find one that doesn't have multiple outputs for one input.
{(-6, -6), (-2,-2), (7,-6),(-5,0)} is the correct answer because all the x are different, and have only one output.

Solve for x:
6x + 9 = 4x + 25
Answer:
x = 8
Step-by-step explanation:
Solve for x:
6 x + 9 = 4 x + 25
Subtract 4 x from both sides:
(6 x - 4 x) + 9 = (4 x - 4 x) + 25
6 x - 4 x = 2 x:
2 x + 9 = (4 x - 4 x) + 25
4 x - 4 x = 0:
2 x + 9 = 25
Subtract 9 from both sides:
2 x + (9 - 9) = 25 - 9
9 - 9 = 0:
2 x = 25 - 9
25 - 9 = 16:
2 x = 16
Divide both sides of 2 x = 16 by 2:
(2 x)/2 = 16/2
2/2 = 1:
x = 16/2
The gcd of 16 and 2 is 2, so 16/2 = (2×8)/(2×1) = 2/2×8 = 8:
Answer: x = 8
The price of apples can be determined by the equation P = 0.23n, where P is the price and n is
the number of apples. What is the constant of proportionality (unit rate)?
Answer:
0.23
Step-by-step explanation:
Basically, the unit rate is how much its increasing every time you add on. So if it were 2+2+2 the unit rate would be 2! Hope this helps!

Answer:
Third option.
Step-by-step explanation:
[tex]5-2\left(3x-9\right)=-1[/tex]
Use the distributive law: [tex]a(b-c)=ab-ac[/tex]
[tex]5-2\times3x-\left(-2\right)\times9=-1[/tex]
Double negative = Positive
[tex]5-6x+18=-1[/tex]
Jose has $178.74 in his checking account. He wrote checks for $36.52, $18.92, and $25.93. He also deposited $300.00, $100.00, and $205.16. What is the final balance in Bob's checking account?V
Answer:
$702.53
Step-by-step explanation:
Start with Jose's initial balance.
[tex]178.74[/tex]
He wrote checks, so we have to subtract the total amount the checks were worth. Let's first add the three amounts.
[tex]36.52+18.92+25.93[/tex]
Solve.
[tex]81.37[/tex]
Subtract the total amount of the checks from Jose's initial balance.
[tex]178.74-81.37[/tex]
Solve.
[tex]97.37[/tex]
The amount above is now what is in Jose's checking account.
But, he also deposited money, meaning he put money in his checking account. Now, let's add the three amounts he deposited.
[tex]300.00+100.00+205.16[/tex]
Solve.
[tex]605.16[/tex]
The amount above is what Jose adds to his checking out.
Add the total value of the deposited money and his new balance.
[tex]605.16+97.37[/tex]
Solve.
[tex]605.16+97.37=702.53[/tex]
m(x) = 4x + 15; m(x) = 7
Hi there! :)
[tex]\huge\boxed{x = -2}[/tex]
m(x) = 4x + 15
Find the value of "x" that would satisfy m(x) = 7:
4x + 15 = 7
Subtract 15 from both sides:
4x = -8
Divide both sides by 4:
x = -2.
9(8 - x) = 3x
Will mark brainlest!
Answer: x = 6
Step-by-step explanation:
9(8 - x) = 3x
72 -9x = 3x
add 9x to both sides
72 = 12x
divide 72 by 12
x = 6

It is given that JKLM is a parallelogram, so JM ll KL by the ____
. Therefore, ∠1 ≅∠2 by the corresponding angles postulate. Also, it is given that _____ ≅∠3, so ∠1≅ ____by the ____
JM is parallel to KL by the definition of parallelogram (opposite sides of any parallelogram are parallel)
Therefore, angle 1 = angle 2 by the corresponding angles postulate
We're also given angle 2 = angle 3
So angle 1 = angle 3 by the transitive property of congruence

4x-6=x+9 i need help can someone show the work too please
Answer:
x = 5
Step-by-step explanation:
instructions in pic :)
4x - 6 = x + 9
4x - 6 - x - 9 = x + 9 - x - 9 [Subtract x + 9 from both sides]
3x - 15 = 0
3x - 15 + 15 = 0 + 15 [Add 15 to both sides]
3x = 15
3x/3 = 15/3 [Divide both sides by 3]
x = 5
Solve this equation.
5(x+8)-1=20+2(x+8)
using the pen

Rewrite (x – 3) (x + 5) + (x – 3) (2x – 1) as the product of two binomials.
(x - 3)(x + 5) + (x - 3)(2x - 1)
We can factor out (x - 3) since both terms have that in common. Then we simply add together x + 5 and 2x - 1
(x - 3)(3x + 4) is the final answer.
Multiply (−7)(2)(−2).

HELP ME PLESA IM DESPO PAKJDCD PLS HELP
Answer:
144 cm²
Step-by-step explanation:
A prism's surface has 2 triangles & 3 rectangles.
In both the triangles , length of :
Perpendicular = 4 cm
Base = 6 cm
So , Area of both triangles = [tex]2(\frac{1}{2} * Base * Perpendicular) = 2(\frac{1}{2}* 6 * 4) = 24 cm^2[/tex]
In the 3 rectangles ,
Length = 8 cm
Width = 5 cm
So , Area of the rectangles = [tex]3( Length * Width) = 3(8 * 5) = 120 cm^2[/tex]
Hence the total surface area of the prism is = 120 + 24 =144 cm²
