Step-by-step explanation:
-2(x + 9) < 16
-2x-18< 16
-2x<34
-x<17
x>-17
x∈(-17;∞)
Answer
x>-17
Step-by-step explanation:
Which of these equations has no solutions?
a
2(x - 7) = 2x - 14
3(2x + 1) = 6x + 1
15x - 30 = 0
2x + 1 = 5x - 3
Answer:
2(x - 7) = 2x - 14
Step-by-step explanation:
→ Expand out equation
2x - 14 = 2x - 14
→ Minus 2x from both sides
-14 = -14
On a coordinate plane, the location of 3 points are: (0, 6). (5. -4), and (-1-5). Where would the fourth point need to be located in order to form a parallelogram?
Given:
The three vertices of parallelogram are (0,6),(5,-4),(-1,-5).
To find:
The fourth vertex of the parallelogram.
Solution:
Consider the given vertices of parallelogram are A(0,6), B(5,-4), C(-1,-5).
Let the fourth vertex be D(a,b).
Midpoint formula:
[tex]Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)[/tex]
We know that the diagonal of parallelogram bisect each other. It means their midpoints are same.
Midpoint of AC = Midpoint of BD
[tex]\left(\dfrac{0+(-1)}{2},\dfrac{6+(-5)}{2}\right)=\left(\dfrac{5+a}{2},\dfrac{-4+b}{2}\right)[/tex]
[tex]\left(\dfrac{-1}{2},\dfrac{1}{2}\right)=\left(\dfrac{5+a}{2},\dfrac{-4+b}{2}\right)[/tex]
On comparing both sides, we get
[tex]\dfrac{5+a}{2}=-\dfrac{1}{2}[/tex]
[tex]5+a=-1[/tex]
[tex]a=-1-5[/tex]
[tex]a=-6[/tex]
And,
[tex]\dfrac{-4+b}{2}=\dfrac{1}{2}[/tex]
[tex]-4+b=1[/tex]
[tex]b=1+4[/tex]
[tex]b=5[/tex]
Therefore, the coordinates of fourth vertex are (-6,5).

(Will Give Brainliest) What is the slope of the line? −4x + 7 = 2y − 3
Answer:
m=-2
Step-by-step explanation:
Answer:
-2
Step-by-step explanation:
-4x + 7 = 2y - 3
7 = 2y - 3 + 4x
0 = 2y - 3 + 4x - 7
-2y = -3 + 4x - 7
-2y = 4x - 10
y = -2x + 5
As the slope of the line is equal to the value of x, the slope of this line is -2

Answer:
It is 24 boxes
Step-by-step explanation:
How many boxes can fit into a cube with a volume of 288
Then, you divide the larger cube's volume(288) by the smaller cube's volume(12)
You will then get 24 boxes.

Solve the equation for all real solutions.
3c^+4c+8=-6c
Answer:
c = -4/3, -2
Step-by-step explanation:
3c^2+4c+8=-6c
3c^2+6c+4c+8=0
3c(c+2) + 4(c+2)=0
(3c+4)(c+2)=0
3c+4=0
c=-4/3c+2=0
c=-2State if the triangles in each pair are similar. If so, state how you know they are similar
And complete the similarity statement.
Answer:
[tex]\triangle LKJ \sim \triangle LHG[/tex]
Step-by-step explanation:
Let suppose that JK and GH are parallel to each other and the length of JK is a multiple of the length of GH ([tex]JK = m\cdot GH[/tex]), then we know that [tex]\angle H \cong \angle J[/tex] and [tex]\angle G \cong \angle K[/tex] by alternate internal angles and [tex]\angle L_{1} \cong \angle L_{2}[/tex] by opposite angles, then [tex]KL = m\cdot GL[/tex] and [tex]HL = m\cdot JL[/tex]. Lastly, we conclude that [tex]\triangle LKJ \sim \triangle LHG[/tex]
Determine if the sequence below is arithmetic or geometric and determine the
common difference / ratio in simplest form.
2, 10, 18, ...
Answer:
Arithmetic sequence; common difference is 8.
Step-by-step explanation:
An arithmetic sequence increases or decreases by a fixed amount from term-to-term.
10 - 2 = 8
18 - 10 = 8
The next term will be 18 + 8 = 26, and so on.
which one is it???????

I’m so confused
And please don’t use the link joke
Answer:
15u + 141 = 420
Step-by-step explanation:
So basically we are modelling how much the coach is spending. Each player is given a uniform and a basketball
We can use 'u' as the cost of a single uniform
We can use 'b' as the cost of a single basketball
Since there is 15 players we must give a ball and uniform to each so
15u + 15b = 420
The problem gives us the cost of each basketball: 9.40
so now 15u + 15(9.4) = 420
15u + 141 = 420

find the value of x by finishing solving the equation shown below
Answer:
Final answer is x = -2
Step-by-step explanation:
-6x-3=9
add 3 to -3 and to 9 (we add 3 because its a negative)
9+3 becomes 12.
now we are left with -6x=12
divide on both sides, -6x divided by -6, and 12 divided by -6.
this leaves us with -2.
x= -2

Answer:
the answer for both of them is x=4/5y-4
Step-by-step explanation:
Step 1: Add 8y to both sides.
10x−8y+8y=−40+8y
10x=8y−40
Step 2: Divide both sides by 10.
10x/10=8y−40/10
x=4/5y−4
Answer:
x=4/5y−4
