Answer:
The answer is 27.
Step-by-step explanation:
When you put it in PEMDAS formation it will look like 9/3x7+6.
9/3 is equivalent to 3 so your formation will now look like 3x7+6. Next step will be 3x7 which equals 21. Your equation will now look like 21+6. And the final step is adding the 21+6, which will give you 21!
Answer:
27
Step-by-step explanation:
PEMDAS
9 divided by 3 = 3
3 x 7 = 21
21 + 6 = 27

help please I dont understand this
Answer:
[tex]x=6[/tex]
Step-by-step explanation:
The lengths of line segments [tex]\overline{AB}[/tex] and [tex]\overline{AC}[/tex] because of the two segments and two angles marked as equal in the diagram. Because of this, the arcs [tex]\widehat{AB}[/tex] and [tex]\widehat{AC}[/tex] are equal.
Since there are 360 degrees in a circle, we can now set up the following equation:
[tex](10x-23)+(10x-23)+106=180,\\20x-46+106=180,\\20x+60=180,\\20x=120,\\x=\boxed{6}[/tex]

3.
5 more than 8
4. 8 less than 2 times a number
3. 8+5
4. 2x - 8
Step-by-step explanation:
3. for example : 5 more than the number means
x+5 so that's how we get the answer as 8+5
4. This can be explained in two folds firstly, for example: 2 less than the number means x-2.
secondly;7 times the number means 7x so therefore we get our final answer as 2x - 8
Grade 9 transformation graph
Answer:
1) D
2) C
3) A
4) B
Step-by-step explanation:
Ok, we need to try each function in the point x = 0 and then analyze the limit as x goes to really large values.
1) g(x) = -3^x
When x = 0, we have:
g(0) = -3^0 = -1
Then we know that the graph of this function will be either A or D.
Now, as x goes to really large values, 3^x will eventually approximate to infinity.
Then - 3^x will approximate to negative infinnity.
From that, we can conclude that the graph for this function is the one that goes to negative infinite as x increases. That is graph D.
2) h(x) = (1/3)^(-x) = 3^x
This is the exact opposite of the previous function. So we need to find the graph that is an exact reflection across the x-axis of graph D, and that one is the graph C.
then the graph if this function is C.
3) k(x) = - (1/3)^x = -1/(3^x)
When x = 0
k(0) = -(1/3)^0 = -1
We have two options with a y-intersect at y = -1 (graph A and D) and in this case, we can see that the part that grows fast is in the denominator, then as x increases, the denominator increases, and thus the function will tend to zero, then the graph of this function is graph A.
4) g(x) = 3^(-x) = 1/(3^x)
g(0) = 1/(3^0) = 1/1 = 1
And same as before, as x increases, g(x) tends to zero.
Then the remaining graph (B) is the graph of this function.
For a bell-shaped distribution with µ = 30, what is the most probable value for the mode?
Answer:
[tex]Mode = 30[/tex]
Step-by-step explanation:
Given
[tex]\mu = 30[/tex] --- Mean
Required
The possible value of the mode
For a bell-shaped distribution, we have:
[tex]Mean = Mode[/tex]
Rewrite as:
[tex]Mode = Mean[/tex]
This gives;
[tex]Mode = \mu[/tex]
Hence:
[tex]Mode = 30[/tex]
Answer:
For a bell-shaped distribution with µ = 30,

which pair of words describes this system of equations 3y=9x-6 2y+6x=4
Answer:
Consistent and dependent
Step-by-step explanation:
Given
[tex]3y = 9x - 6[/tex]
[tex]2y + 6x = 4[/tex]
Required
The words that describe the equations
Make y the subject in (2)
[tex]2y + 6x = 4[/tex]
Collect like terms
[tex]2y = 4 - 6x[/tex]
Divide through by 2
[tex]y = 2 - 3x[/tex]
Substitute: [tex]y = 2 - 3x[/tex] in (1)
[tex]3y = 9x - 6[/tex]
[tex]3(2 - 3x) = 9x - 6[/tex]
[tex]6 - 9x = 9x - 6[/tex]
Collect like terms
[tex]9x+9x = 6+6[/tex]
[tex]18x = 12[/tex]
Solve for x
[tex]x = \frac{12}{18}[/tex]
Simplify
[tex]x = \frac{2}{3}[/tex]
Substitute [tex]x = \frac{2}{3}[/tex] in [tex]y = 2 - 3x[/tex]
[tex]y = 2 - 3*\frac{2}{3}[/tex]
[tex]y = 2 - 2[/tex]
[tex]y =0[/tex]
So, we have:
[tex]x = \frac{2}{3}[/tex] and [tex]y =0[/tex]
The system is consistent because it has at least 1 solution
The system is dependent because it has more than 1 solution

Answer:
See attachment for graph
Step-by-step explanation:
Given
[tex]y = x^2 - 3[/tex]
Required
The graph of the equation
First, we determine the range of y
[tex]x = -3[/tex]
[tex]y = x^2 - 3 \to y = (-3)^2 - 3 = 6[/tex]
[tex](-3,6)[/tex]
[tex]x = -2[/tex]
[tex]y = (-2)^2 - 3 = 1[/tex]
[tex](-2,1)[/tex]
[tex]x = -1[/tex]
[tex]y = (-1)^2 - 3 = -2[/tex]
[tex](-1,-2)[/tex]
[tex]x=0[/tex]
[tex]y = 0^2 - 3 = -3[/tex]
[tex](0,-3)[/tex]
[tex]x = 1[/tex]
[tex]y= 1^2 - 3 = -2[/tex]
[tex](1,-2)[/tex]
[tex]x = 2[/tex]
[tex]y =2^2 - 3 = 1[/tex]
[tex](2,1)[/tex]
[tex]x = 3[/tex]
[tex]y = 3^2 - 3 = 6[/tex]

Least Common Multiple (LCM) :-2 | 6 , 42 | 3 , 23 | 3 , 1 | 1 , 1LCM → 2 × 2 × 3= 4 × 3= 12✍ The least common multiple of six (6) and four (4) is twelve (12).Which set of numbers does NOT represent the lengths of the sides of a triangle? (6, 18, 23) (6, 22, 17) (16, 24, 7) (22, 8, 15
Answer:
(16, 24, 7)
Step-by-step explanation:
The Triangle Inequality states that the sum of lengths of any two sides should be greater than the length of the third side.
But 16 + 7 = 23 is not greater than 24.

d(n)=6-4(n-1) Find the fifth term in the sequence
Answer:
5th term: -10
Step-by-step explanation:
To find the nth term in the sequence, you can substitute n into the equation:
d(n) = 6 - 4(n - 1)
Since we want the 5th term, we substitute 5:
d(5) = 6 - 4(5 - 1)
d(5) = 6 - 4(4)
d(5) = 6 - 16
d(5) = -10

Step-by-step explanation:
Answer:
The value of [tex]q[/tex] is [tex]\mathbf{6}[/tex]
Step-by-step explanation:
The sum of the angles [tex](9q-8)^\circ[/tex] and [tex]134^\circ[/tex] should be equal to [tex]180^\circ[/tex]
[tex](9q-8)+134^\circ=180^\circ[/tex]

A surveyor has a survey a triangular plot of land. One side of the plot lies along countryside road. This side is 400 ft long. The second side is the gore road, which intersects countryside road at an angle of 88 degrees. The third side of this plot of land is 550 ft long. Determine the distance of the gore road that makes up in the unknown side of plot to the nearest foot
9514 1404 393
Answer:
392 ft
Step-by-step explanation:
As in the attached figure, you seem to have sides b and c of the triangle, along with angle C. You want to find side 'a'. The law of sines can be used to find angle B, then angle A can be found from the sum of angles. Knowing angle A, we can find side 'a'.
sin(B)/b = sin(C)/c
sin(B) = (b/c)sin(C) = 400/550·sin(88°)
B = arcsin(8/11·sin(88°)) ≈ 46.621°
Then angle A = ...
A = 180° - B - C = 180° -46.621° -88° = 45.379°
Now, we can find side 'a' from ...
a/sin(A) = c/sin(C)
a = c·sin(A)/sin(C) ≈ 550·sin(45.379°)/sin(88°) ≈ 391.710 . . . feet
The unknown side of the triangle is about 392 feet.
