A triangular prism has a valine of 8460 in if the height of the prism is 9 in
(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
which one is it???????

wish that will help u
Please help!!
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
I need help finishing RT. Please help. I do not know what to do. Any help will be appreciated:))
Answer:
RT = 86
Step-by-step explanation:
Here, we want to find the value of RT
looking at the given triangle, we can deduce that the smaller triangle SPQ is half the measure of the bigger triangle SRT
what this mean is that we have to multiply the dimensions on SPQ by 2 to get the equivalent dimensions of similar sides in SRT
Thus, we have it that;
2(15x -17) = 23x -6
30x - 34 = 23x -6
30x -23x = -6 + 34
7x = 28
x = 28/7
x = 4
So, we make a substitution
for RT;
23x-6
= 23(4) - 6 = 92-6 = 86
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).
Which of these equations has no solutions?

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

A depreciation of 5% from the original 100% is
100% - 5% = 95% = [tex]\frac{95}{100}[/tex] = 0.95
Find the slope of the line.
(0,2) (2,-2)
Will give brainiest if correct
Answer: -2
The slope is 4/2 and you simplify it inti 2. And since the line is going down, it’s a negative slope, so the answer will be -2.

The product of two rational numbers is -42/63. One of the rational numbers is 7/27. Find the other.
Chapter : Rational Numbers
Answer:The other rational number= -18/7
Step-by-step explanation:
The product of the two rational numbers is -42/63.
One of the rational number=7/27
The other rational number whch can be called R can be gotten by diving the product by the rational numvber goven
R x 7/27 =-42/63.
-42/63 ÷ 7/27=R
R=-42/63 X 27/7
R= -18/7

Can someone help me with this question please
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

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.

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]

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
