Answer:
x = 1
Step-by-step explanation:
4x+7(3x-3) = 9-5x (equation)
4x+21x-21 = 9-5x (simplify)
25x-21 = 9-5x (combine like terms)
30x-21 = 9 (add 5x to each side)
30x = 30 (add 21 to each side)
x = 1 (divide each side by 30)
find the zeros of the equation 4x²-3x+9=2x+1

Answer:
Jedi light saber: 6 ftDarth light saber: 5 ftStep-by-step explanation:
Given
a = 37b = 63c = 16Find
The length of each light saber, rounded up to the nearest foot.
Solution
The attached scale drawing shows the triangles with the angles and sides filled in.
The angle at the Jedi's hand is 2a = 2(37°) = 74°. If L represents the Jedi's light saber length, then the cosine relation is useful:
Cos = Adjacent/Hypotenuse
cos(74°) = (1.4 ft)/L
L = (1.4 ft)/cos(74°) ≈ 5.08 ft
Rounded up to the nearest foot, the Jedi's light saber is 6 ft long.
__
The angle at Darth's hand is ...
5c = 5(16°) = 80°
and the length of the opposite side is ...
b/14 = 63/14 = 4.5 . . . feet
The sine relation is useful here. If L represents Darth's light saber length, then ...
Sin = Opposite/Hypotenuse
sin(80°) = (4.5 ft)/L
L = (4.5 ft)/sin(80°) ≈ 4.57 ft
Rounded up to the nearest foot, Darth's light saber is 5 ft long.

Complete the table by computing the amount in the account at the end of each period.
Answer:
See below
Step-by-step explanation:
Initial Principal P₀ = 1000End of first period = 1000 + 1000*0.02/4 = 1005End of second period = 1005 + 1000*0.02/4 = 1010End of third period = 1010 + 1000*0.02/4 = 1015End of fourth period = 1015 + 1000*0.02/4 = 1020
Find the slope of the line passing through the points (-6, 2) and (-6, -1).
Answer:
3/0
Step-by-step explanation:
to find the slope use rise over run or y-y/x-x, in this case, 2-(-1)/-6-(-6)the negative and the subtraction sign cancel out resulting in something like this: 2+1/-6+6 equaling 3/0

Which type of discontinuity exists at x=0?
Answer:
removable
Step-by-step explanation:
f(x) = cos(1/x^2) at x = 0;
For the function f(x) = cos(1/x^2) let's substitute the value of 0 in for x...
= cos(1/(0)^2)
= cos(1/0)
Now remember that x/0 is undefined. Removable discontinuity is undefined at the point x₀, and hence our solution is "removable."

A = πab/4 solve for b
Answer:
4A/ (πa) = b
Step-by-step explanation:
A = πab/4
Multiply each side by 4
4A = 4πab/4
4A = πab
Divide each side by πa
4A/(πa) = πab/ πa
4A/ (πa) = b

Answer:
the marked answer is correct
Step-by-step explanation:
The desired end result is an identity matrix in the first three columns. The diagonal values are 1, as needed, so what remains is to eliminate the off-diagonal values. In row 2 that can be done by adding row 3 to it.
The next step should be to add rows 2 and 3 and replace row 2 with that sum.

Find a equation that matches the graph.
Answer:
x ≥ 3
Step-by-step explanation:
The closed dot represents ≥ and ≤
The dot is located on the number "3"
The closed dot essentially shows that the solution is nothing more than 3 and up.
Let "x" be the variable we use.
x ≥ 3
Best of Luck!
The above never line shows the possible values of an variable in any expression.
Through Observation:
The arrow pointing from 3 to infinity.3 is represented by a closed dot.The value is starting from 3 to infinity.Hence, the required value of the variable can be equal to 3 or greater than 3 for that expression. This can be written as:
[tex] \large{ \boxed{ \rm{ x\geqslant 3}}}[/tex]

A theater owner wants to divide a 3300 seat theater into three sections, with tickets costing $ 60, $70, and $120, depending on the section. He wants to have twice as many $60 tickets as the sum of the other tickets, and he wants to earn $ 224,000 from a full house. Find how many seats he should have in each section.
Answer:
Section A = 2,200 seats
Section B = 800 seats
Section C = 300 seats
Step-by-step explanation:
Three sections
Section A cost = $60
Section B cost = $70
Section C cost = $120
Total seat = 3300
Total earnings = $224,000
He wants to have twice as many $60 tickets as the sum of the other tickets
A = 2(B + C)
A + B + C = 3,300
60A + 70B + 120C = 224,000
substitute A = 2(B + C)
2(B + C) + B + C = 3,300
60(2B + 2C) + 70B + 120C = 224,000
2B + 2C + B + C = 3,300
120B + 120C + 70B + 120C = 224,000
3B + 3C = 3,300 (1)
190B + 240C = 224,000 (2)
Multiply (1) by 80
240B + 240C = 264,000 (3)
190B + 240C = 224,000 (2)
Subtract the equations
240B - 190B = 264,000 - 224,000
50B = 40,000
B = 40,000 / 50
= 800
B = 800
Substitute the value of B into (1)
3B + 3C = 3,300 (1)
3(800) + 3C = 3,300
2,400 + 3C = 3,300
3C = 3,300 - 2,400
3C = 900
C = 900 / 3
= 300
C = 300
Substitute values of B and C into
A + B + C = 3,300
A + 800 + 300 = 3,300
A + 1,100 = 3,300
A = 3,300 - 1,100
= 2,200
A = 2,200
Section A = 2,200 seats
Section B = 800 seats
Section C = 300 seats
A line passes through the points (-2, 9) and (1, 3).
provide work for calculating the slope and y-intercept. Then, write the equation for the line in slope-intercept form.
Finding slope: y2-y1/x2-x1
3-9/1+2
=-6/2
Divide 2 from both
=-3/1 or -3
Slope= -3
Finding y-intercept= y=mx+b
Choose any point on the line to plug in the x and the y then plug in the slope.
I choose (1,3)
3=-3×1+b
3=-3+b
Add 3 to both sides
6=b
Y-intercept=6

(5 Points)
d = 169
d = 309
d=249
d=129
Answer:
[tex] d = 24g [/tex]
Step-by-step explanation:
The graph shows a proportional relationship between distance travelled in miles and the gallons of gas used. Thus, a simple equation can be written to represent this relationship by simply applying the the equation that describes a proportional relationship.
Equation representing a typical proportional relationship is y = kx, where k is the constant of proportionality.
In this case,
y = distance in miles travelled represented by d
x = gallons of gas used represented by g
k = constant of proportionality which is distance travelled per gallon = [tex] \frac{d}{g} = \frac{120}{5} = 24 [/tex]. (note: to get k, you can use any coordinate pair of a point in the line graph).
Therefore, an equation that can be used to find the distance travelled is:
[tex] d = 24g [/tex]

What is the smallest value of x that makes this inequality true?
2/3(4x-1)-6 is greater than or equal to, 7-(2x+9)
Answer:
it may be helpful for youAnswer:
x = 1 is trueStep-by-step explanation:
2/3(4x - 1) - 6 ≥ 7 - (2x + 9)
remove parenthesis:
2/3*4x - 2/3*1 - 6 ≥ 7 - 2x + 9
simplify:
8x/3 - 2/3 - 6 ≥ 2x - 2
combine similar terms:
8x/3 + 2x ≥ -2 + 2/3 + 6
simplify 14/3x ≥ 14/3
finally x = 1 is true
