9 subtracted from 2x gives the result 5 Find the value of x.
Answer:
x = 7
Step-by-step explanation:
Just write what you see in terms of a formula.
2x - 9 = 5
Solve for x
add both sides by 9
2x = 5 + 9
2x = 14
divide both sides by 2
x = 14/2
x = 7
Answer:
x = 7
Step-by-step explanation:
9 subtracted from 2x gives the result 5. Find the value of x.
Translate:
2x - 9 = 5
Simplify:
2x - 9 = 5 <== add 9 to both sides
+ 9 + 9
2x = 14 <== divide both sides by 2 to isolate the variable
/2 /2
x = 7

What is the sum of the six marked angles in the picture?
Answer:
The answer is option D - 1120°
1120° is the sum of the sixed marked angle in the picture. Therefore, the correct option is option D.
What is angle?
An angle is a figure in Euclidean geometry made up of two rays that share a common terminal and are referred to as the angle's sides and vertices, respectively. Angles created by two rays are in the plane where the rays are located. The meeting of two planes also creates angles. We refer to these as dihedral angles.
The angle formed by the rays lying perpendicular to the two crossing curves at the point of junction is another property of intersecting curves. Angle can also refer to the size of such an angle or a rotational angle. The width of a circular path divided by its radius is the traditional definition of this metric, which may also be signed. 1120° is the sum of the sixed marked angle in the picture.
Therefore, the correct option is option D.

Find the equation of a line parallel to y + 9 = -3/2x that passes through the point (-8,9)
Solve the system of equations below. 4x+1=16 2x+30= - 2
Answer:
D. (5, 4)
Step-by-step explanation:
4x + y = 16 -----> y = 16 - 4x
2x + 3y = -2
Substitute to find x
2x + 3(16 - 4x) = -2
2x + 48 - 12x = -2
-10x = -50
x = 5
Substitute to find y
4(5) + y = 16
20 + y = 16
y = 4

FREE BRAINLIEST IF CORRECT - EZ QUESTION: Write the equation for the parabola that has x− intercepts (−2,0) and (−5,0) and y− intercept (0,−4).
Answer:
y = -2/5x^2 - 14/5x - 4
Step-by-step explanation:
y = a(x + 2)(x + 5)
At y intercept:
-4 = a(2)(5)
10a = -4
a = -2/5.
So the equation is
y = -2/5(x + 2)(x + 5)
y = -2/5(x^2 + 7x + 10)
y = -2/5x^2 - 14/5x - 4

circle
ellipse
parabola

Answer: B "ellipse"
to check what type of conic it may be, we first check the squared variables, their coefficents and sign.
in this case 2x² and 5y² are both positive, that means we have either an ellipse or a circle.
if the coefficients are equal, boinggggg! we have a circle, or if you wish an ellipse with equal axes.
if the coefficients are different, like in this case, we have an ellipse.

express x in terms of a and N, giving your answer in a form not involving logarithms.
Answer:
N/a^3/2
Step-by-step explanation:
loga(N/X)=3/2
N/X= a^3/2
X= N/a^3/2
Step-by-step explanation:
When subtracting logarithms with the same base, it is equivalent to combining them into one logarithm, then dividing the arguments inside:
[tex] log_{a}(n) - log_{a}(x) = log_{a}( \frac{n}{x} ) [/tex]
Then use the formula:

[tex]{a}^{ \frac{3}{2} } = \frac{n}{x} [/tex]
[tex]x = n {a}^{ - \frac{3}{2} } [/tex]

The 9th term of the geometric sequence will be 41,990,400.
What is a geometric sequence?A series of non-zero integers where every term after the first is obtained by increasing the one before it by a constant, non-zero value known as the scale factor.
Let a₁ be the first term and r be the common ratio. Then the nth term of the geometric sequence is given as,
aₙ = a₁ · (r)ⁿ⁻¹
The sequence is given below.
25, 150, 900, .....
The first term is 25 and the common ratio is calculated as,
r = 150 / 25
r = 6
Then the 9th term of the sequence is given as,
a₉ = 25 · (6)⁹⁻¹
a₉ = 25 · (6)⁸
a₉ = 25 · 1,679,616
a₉ = 41,990,400
The 9th term of the geometric sequence will be 41,990,400.

What’s bigger - 2/3 or -0.8
Answer:
-2/3 is greater than -0.8
Step-by-step explanation:
-2/3 when made into a decimal is about -0.67
This is greater than -0.8 because -0.67 covers less area when put into a visual.
Answer:
Convert -0.8 into a fraction or -2/3 into a decimal;
-2/3 in decimal form = -0.666...
Compare the two decimals;
-0.8 __ -0.666...
-0.8 < -0.666..., so -2/3 is greater.

Carter invested $540 in an account paying an interest rate of 4. 875 % compounded monthly. Jack invested $540 in an account paying an interest rate of 5. 5% compounded continuously. To the nearest hundredth of a year, how much longer would it take for Carter's money to triple than for Jack's money to triple?
Using compound interest and continuous compounding, it is found that it would take 2.61 years longer for Carter's money to triple.
What is compound interest?The amount of money earned, in compound interest, after t years, is given by:
[tex]A(t) = P\left(1 + \frac{r}{n}\right)^{nt}[/tex]
In which:
A(t) is the amount of money after t years. P is the principal(the initial sum of money). r is the interest rate(as a decimal value). n is the number of times that interest is compounded per year.For Carter, we have that the rate of interest and the number of compoundings are, respectively, r = 0.04875 and n = 12. The time to triple is t for which A(t) = 3P, hence:
[tex]A(t) = P\left(1 + \frac{r}{n}\right)^{nt}[/tex]
[tex]3P = P\left(1 + \frac{0.04875}{12}\right)^{12t}[/tex]
[tex](1.0040625)^{12t} = 3[/tex]
[tex]\log{(1.0040625)^{12t}} = \log{3}[/tex]
[tex]12t\log{(1.0040625)} = \log{3}[/tex]
[tex]t = \frac{\log{3}}{12\log{(1.0040625)}}[/tex]
t = 22.58.
What is continuous compounding?The amount of money is given by:
[tex]A(t) = Pe^{kt}[/tex]
For Jack, we have that the rate of interest is of k = 0.055, hence:
[tex]A(t) = Pe^{kt}[/tex]
[tex]3P = Pe^{0.055t}[/tex]
[tex]e^{0.055t} = 3[/tex]
[tex]\ln{e^{0.055t}} = \ln{3}[/tex]
[tex]0.055t = \ln{3}[/tex]
[tex]t = \frac{\ln{3}}{0.055}[/tex]
t = 19.97.
The difference is given by:
22.58 - 19.97 = 2.61
It would take 2.61 years longer for Carter's money to triple.

1/secA+tanA = 1-sinA/cosA
Answer:
Below.
Step-by-step explanation:
1 / secA+tanA = 1 / [1/cosA+sinA/cosA))]
= 1/ [(1 + sinA)/cosA]
= cosA/(1+sinA)
Now check if this is identical to 1-sinA/cosA:
1-sinA/cosA = cosA/(1+sinA)
Cross multiply:
(1-sinA)(1+sinA) = cos^2A
1 - sin^2A = cos^2A
sin^2A + cos^2A = 1
This is a known idenity.
So the original identity is true.

In 1 dollar there are 100 cents and we write them after a period:
1 cent of a dollar is written $0.01.
10 cents of a dollar is written $0.10.
1 dollar and 1 cent is written $1.01.
1 dollar and 10 cents is written $1.10.
Money Is a Special Decimal
All money is a decimal value with two places. You will see examples including $1.25, $65.98, and $26.34. No matter how big the value gets, you can only have two decimal places. One cent is 0.01.

What is the probability of rolling a 6 or landing on tails?
Enter your answer as a reduced fraction, like this: 3/14
Answer:
1/3
Step-by-step explanation:
If you are trying to figure out the more likeliness of getting tails than a 6, then you have to get a common denominator and then subtract numerators.
[tex]\frac{1}{2} =\frac{6}{12} \\\\\frac{1}{6} =\frac{2}{12} \\\\\frac{6}{12} -\frac{2}{12} =\frac{4}{12} \\\\\frac{4}{12} =\frac{2}{6} =\frac{1}{3}[/tex]
Theres a 1/3 more chance of tails than rolling 6
The probability of rolling a 6 or rolling a die is 2/3.
What is Probability?Probability is simply the possibility of getting an event. Or in other words, we are predicting the chance of getting an event.
The value of probability will be always in the range from 0 to 1.
Given that,
An experiment consists of rolling a die and then flipping a coin.
Probability = Number of desired outcomes / Total outcomes
Probability of rolling a 6 = 1/6
Probability of landing on tails = 1/2
P(A or B) = P(A) + P(B)
Here, let A represents the event of rolling 1 6 and B represents the event of landing on tails.
P(A or B) = 1/6 + 1/2 = 4/6 = 2/3
Hence the required probability is 2/3.
