Answer:
x = -1/12
Step-by-step explanation:
q(x) = 12x − 3
q(x) = −4
-4 = 12x − 3
12x - 3 = -4
12x = -4 + 3
12x = -1
x = -1/12
(4) + (14 – 4i) =

A circle has circumference 27 cm. What is the area of the circle? Use 3.14 for .
Circumference = 2πr = 27 cm
= 2 × 3.14 × r = 27
= 3.14 × r = 27/2
so, r = [tex]\frac{27}{2}[/tex] × [tex]\frac{1}{3.14}[/tex] = 4.2 cm
Can I plz have some help with this...?
Answer:
x=19
Step-by-step explanation:
The sum of the three anagles is 180
(5x+4)+(x-2)+(3x+7)=180
5x+x+3x+4-2+7=180
9x+9=180
9(x+1)=180
x+1=20
x=20-1
x=19

how many square feet of outdoor carpet will we need for this hole?
MY WORK:
First, you would cut it up into different parts/shapes
(I cut it up into rectangles)
Then, you would find the area of each.
The bottom rectangle: 10 ( 5 times 2 )
The middle rectangle: 12 ( 6 times 2 )
The top rectangle: 8 ( 4 times 2 )
Lastly, you would add!
10 + 12 + 8 = 30
Therefore, the answer is...
30!

Answer:
I think it is 72%
Step-by-step explanation:
Answer:
A. 12%
Step-by-step explanation:
I counted the number of dots in all, and the number of dots in the columns 7 - 8.
There are 25 dots in allThere are 3 dots in columns 7 - 8.This means that 3/25 of the students in the class have 7 - 8 people in their houses.
Now let's convert the fraction into a decimal, which we'll then convert into a percent.
Let's multiply the numerator and denominator of 3/25 by 4.
We get 12/100!
12/100 as a decimal is 0.12
0.12 as a percent is 12%
Is there a letter which has 12% as an option? Yes, there is! It's A.
The answer is A. 12%
This week, the art museum gave away 1,200 tickets to the Greco exhibit, which was 150 percent as many tickets as it gave away last week. Martin is trying to figure out how many tickets the museum gave away last week. His work is shown below.
Step 1: StartFraction part Over whole EndFraction = StartFraction 150 Over 100 EndFraction = StartFraction question mark Over 1200 EndFraction
Step 2: 100 times 12 = 1200
Step 3: 150 times 12 = 1800
In what step did Martin make a mistake, if any?
Step 1: Martin should have written his ratio as StartFraction 1200 Over question mark EndFraction.
Step 2: Martin should have divided 1200 by 8.
Step 3: Martin should have added 1200 and 150.
Martin did not make any mistakes.

The sale price of an item is $330 after a 25% discount. What was the original price of the item?
Answer:
The original price of the item is $440.
Step-by-step explanation:
If you have a discount for 25% and the resulting price is 330, then 330 is 75% of the original price.
Because of the way my brain works, my first thought was that if $330 is 75% of the original price then, 1/3 of 330 would be 25% of the original price. So, I multiplied 330 by 1/3 and got 110. Then I added 110 and 330 to get 440, the original price.

Hope this helped!Find the 29th term in the arithmetic sequence: -13, -6, 1, 8........
Answer:
183
Step-by-step explanation:
a₁ = -13
common difference = a₂ - a₁
= (-6) - (-13)
= -6 + 13
d = 7
nth term = a₁ + (n - 1)d
29th term = -13 + 28 * 7
= -13 + 196
= 183
In one part of a kennel, 5/8 of the 24 dogs are male. In another part of the kennel, 4/5 of the 30 dogs are male.
How many male dogs are in the two parts of the kennel?
Answer:
39
Step-by-step explanation:
The computation of the number of male dogs in the two parts of the kennel is shown below:
In one part, the male dogs are
= 24 × 5 ÷ 8
= 15
In the another part, the male dogs are
= 30 × 4 ÷ 5
= 24
So, the total male dogs is
= 15 + 24
= 39

complete the algebraic table for y = 2x + 3
given: x ---> -2, -1, 0, 1, 2, 3
y ----> ?, 1, ?, ?,7,?
Answer:
y ----→ -1 , 1 , 3 , 5 , 7 , 9
Step-by-step explanation:
LINEAR EQUATION GIVEN IN THE QUESTION :- y = 2x + 3
In the question , some values of variable 'x' are given. Lets put each value of 'x' in the equation.
When x = -2 ; [tex]y = 2(-2) + 3 = -4 + 3 = -1[/tex]When x = -1 ; [tex]y = 2(-1) + 3 = -2 + 3 = 1[/tex]When x = 0 ; [tex]y = 2(0) + 3 = 0 + 3 = 3[/tex]When x = 1 ; [tex]y = 2(1) + 3 = 2 + 3 = 5[/tex]When x = 2 ; [tex]y = 2(2) + 3 = 4 + 3 = 7[/tex]When x = 3 ; [tex]y = 2(3) + 3 = 6 + 3 = 9[/tex]Thus , we got all the required values of y.

Find the standard form of the equation for the conic section represented by x^2 + 10x + 6y = 47.
Answer:
The standard form of the equation for the conic section represented by [tex]x^2\:+\:10x\:+\:6y\:=\:47[/tex] is:
[tex]4\left(-\frac{3}{2}\right)\left(y-12\right)=\left(x-\left(-5\right)\right)^2[/tex]
Step-by-step explanation:
We know that:
[tex]4p\left(y-k\right)=\left(x-h\right)^2[/tex] is the standard equation for an up-down facing Parabola with vertex at (h, k), and focal length |p|.
Given the equation
[tex]x^2\:+\:10x\:+\:6y\:=\:47[/tex]
Rewriting the equation in the standard form
[tex]4\left(-\frac{3}{2}\right)\left(y-12\right)=\left(x-\left(-5\right)\right)^2[/tex]
Thus,
The vertex (h, k) = (-5, 12)
Please also check the attached graph.
Therefore, the standard form of the equation for the conic section represented by [tex]x^2\:+\:10x\:+\:6y\:=\:47[/tex] is:
[tex]4\left(-\frac{3}{2}\right)\left(y-12\right)=\left(x-\left(-5\right)\right)^2[/tex]
where
vertex (h, k) = (-5, 12)
The two triangles above are similar. If r = 19, v = 18, and u = 21, what is the value of s? Round answer to the nearest hundredth (2 decimal places).
Answer:
s=22.17
Step-by-step explanation:
v/r=u/s
18/19=21/s
18s=21(19)
18s=399
18s/18=399/18
s=22.17
