Which expression is equivalent to (-18) - 36n?
Answer:
D
Step-by-step explanation:
-18 - 36n = -6(3 + 6n).
Use distributive property.
-6(3 + 6n)
-18 + (-36n)
-18 - 36n
-18 - 36n = -18 - 36n
Have a nice day!
Answer:
D. -6 (3 + 6n)
Step-by-step explanation:
When you distribute [tex]-6 (3 + 6n)[/tex], you get [tex]-18 + -36n.[/tex]
[tex]-18 + -36n = (-18) - 36n.[/tex]

solve by elimination 5x+2y=-11 and 3x+2y=-9
Answer:
[tex]5x + 2y = - 11 - - - (a) \\ 3x + 2y = - 9 - - - (b) \\ (a) - (b) : \\ 2x + 0y = - 2 \\ x = - 1 \\ (3 \times - 1) + 2y = - 9 \\ - 3 + 2y = - 9 \\ 2y = - 6 \\ y = - 3 \\ { \boxed{x = - 1}} \\ { \boxed{y = - 3}}[/tex]
Answer:
(- 1, - 3 )
Step-by-step explanation:
Given the 2 equations
5x + 2y = - 11 → (1)
3x + 2y = - 9 → (2)
Subtract (2) from (1) term by term to eliminate y
2x = - 2 ( divide both sides by - 2)
x = - 1
Substitute x = - 1 into either of the 2 equations and solve for y
Substituting into (1)
5(- 1) + 2y = - 11
- 5 + 2y = - 11 ( add 5 to both sides )
2y = - 6 ( divide both sides by 2 )
y = - 3
solution is (- 1, - 3 )

Answer:
I don’t know
Step-by-step explanation:
Write the quadratic equation in standard form.
Step-by-step explanation: If we want to put this in standard form, we first want to add 2x² to both sides of the equation to get 2x² + 5x - 17 = 0.
Notice that I have set up the left side of the equation in descending order of powers. In other words, first the x² term, then the x term, then the constant term.
A line passes through the point (12,-4) and is perpendicular to the line with the
equation y = 6x + 3. What's the equation of the line?
A) y = 6x - 76
B) y= -1/64 - 2
C) y= -4/5x+ 2
D) y = -6x + 68
Answer:
y = -1/6x - 2
Step-by-step explanation:
y = -1/6x + b
-4 = -1/6(12) + b
-4 = -2 + b
-2 = b

What is the value of x?
Step-by-step explanation:
Hello! x = 24 This is a complementary angle so it will add up to 90 degrees in total so 24 × 3 = 72 and 72 - 6 = 66 and 66 + 24 = 90 so x = 24 HOPE THAT HELPS!
Answer:
X = 24
Step-by-step explanation:
so you will have to add all the angles and get 90
3x - 6 +x=90
4x =96
x=24
check your answer.
3 x 24
72 -6 = 66
66 +24 = 90
Which statement about convergent infinite geometric series is true?
a.The graph of a convergent infinite geometric series goes to infinity.
b.The graph of an infinite geometric series curves away from its sum.
c.A finite geometric sequence will have an infinite geometric series.
d.An infinite geometric series converges if −1
Answer:
B. The graph curves away from its sum
Step-by-step explanation:
A convergent infinite geometric series, the graph of the series curves away from the sum, the correct option is B.
What is a Geometric Series?A sequence of numbers such that the consecutive term is increasing or decreasing by a fixed ratio is called a geometric series.
The standard equation for geometric series is
Tₙ = a₁ rⁿ⁻¹
The sum of an infinite geometric series is given by
S = a₁/(1-r)
where a₁ is the first term and r is the common ratio.
The graph of an infinite series curves away from its sum.

Answer:
Hello! answer: b = 75
Step-by-step explanation:
We have to find b so we have to work backwards to find the answer the steps would be to find c^2 subtract that by a^2 and then you get b^2 and have to find out what multiplied by itself equals b^2 so... 85 × 85 = 7225 40 × 40 = 1600 7225 - 1600 = 5625 75 × 75 = 5625 therefore b = 75 hope that helps!
Solve for x the triangles In Each pair LMN~LRS
Please help quickly and show work pleasee
Given:
[tex]\Delta LMN\sim \Delta LRS[/tex]
To find:
The value of x.
Solution:
We have,
[tex]\Delta LMN\sim \Delta LRS[/tex]
We know that the corresponding sides of similar triangles are proportional. So,
[tex]\dfrac{LM}{LR}=\dfrac{LN}{LS}[/tex]
[tex]\dfrac{18}{2x-18}=\dfrac{30}{10}[/tex]

[tex]18=3(2x-18)[/tex]
Using distributive property, we get
[tex]18=3(2x)-3(18)[/tex]
[tex]18=6x-54[/tex]
[tex]18+54=6x[/tex]
[tex]72=6x[/tex]
Divide both sides by 6.

Answer:
D) 100% Positve
Step-by-step explanation:
You would choose the second option (y=1/3x) because the slope would be 1/3. Think of the slope as your directions, you go up 1 over to the right 3 times. Since the y-intercept is 0, you don't have to add anything at the end.

The weight, in pounds, of a newborn baby t months after birth can be modeled by the equation W=10+2t What is the slope of the equation and what is its interpretation in the context of the problem?
Answer:
m = 2
Step-by-step explanation:
W=10+2t has the form y = mx + b, the slope-intercept form. Comparing
y = b + mx to
w = 10 + 2t
we see that the slope, m, is 2. This signifies that the baby gains 2 pounds per month shortly after birth.

A student is standing 20 feet away from the base of a tree. he looks to the top of the tree from a 50 degree angle of elevation. His eyes are 5 feet above the ground. using cos 50°≈0.64, what is the height of the tree to the nearest foot?
A. 29 feet
B. 24 feet
C. 31 feet
D. 36 feet
Answer:
A. 29 feet
Step-by-step explanation:
Use cos to find the hypotenuse
cos = adj/hp
0.64 = 20/hyp
hyp = 20/0.64
hyp = 31.25
---------------------------
Use Pythagorean Theorem to find the height of tree above eyes
a² + b² = c²
a² + 20² = 31.25²
a² = 31.25² - 20²
a² = 576.5625
a = 24 (to the nearest foot)
-------------------------------
Finally add in the eye height
h = 24 + 5
h = 29 feet

A. 29 feet
