6. Which expression is equivalent to
7(k + 3) - 18?
A. 7.k+7.3 - 7. 18
B. 7.k+7.3 - 18
C. 7.k+3 - 18
D. None of these
Answer:
B. 7.k+7.3-18
Step-by-step explanation:
Distributive Property,
7 (k+3) = 7 x k + 7x 3
Find a value of x that is a solution to 5(x – 3) = x + 13.
Answer:
x = 7
Step-by-step explanation:
[tex]5(x-3)=x+13[/tex]
distribute
[tex]5x-15= x+13[/tex]
combine like terms
[tex]5x-x = 13 + 15[/tex]
[tex]4x=28[/tex]
x = 7
Answer:
x=7
Step-by-step explanation:
[tex]5(x-3)=x+13\\5x-15=x+13\\Subtract x from both sides \\4x-15=13\\Add 15 to both sides\\4x= 28\\Divide both sides by 4\\x=7[/tex]
Now check your answer
[tex]5(7-3)=7+13\\35-15=20\\20=20[/tex]
Which expression is NOT equal to 729? 3 × 3 × 3 × 3 × 3 × 3 6,3 9 × 9 × 9 36
Answer:
Rewrite as an equation.
log
9(729)=x
Rewrite
log
9(729)=x
in exponential form using the definition of a logarithm. If
x and b
are positive real numbers and b
does not equal 1, then log b(x)=y is equivalent to by=x. 9x=729
Create expressions in the equation that all have equal bases.
(32)x=3
Rewrite
(32)x as 32x. 32x=36
Since the bases are the same, then two expressions are only equal if the exponents are also equal.
2 x 3=6
Solve for
x.x=3
The variable x
is equal to
3.3
Step-by-step explanation:
The expression not equal to 729 is 6³
What are exponents?Exponents, also known as powers, are values that show how many times to multiply a base number by itself. For example, 43 is telling you to multiply four by itself three time:4³= 4 × 4 × 4 = 64
Given here 3⁶= 3×3×3×3×3×3
= 729
6³ = 6×6×6
= 216
9³ = 9×9×9
= 729
Hence 6³ is the expression not equal to 729

Leila will rent a car for the weekend. She can choose one of two plans. The first plan has an initial fee of $40 and costs an additional $0.13 per mile driven. The second plan has an initial fee of $53 and costs an additional $0.08 per mile driven
9514 1404 393
Answer:
260 miles$73.80Step-by-step explanation:
The cost of each plan (y) is the sum of the initial fee and the product of the mileage charge and the number of miles (x).
First Plan: y = 40 +0.13x
Second Plan: y = 53 +0.08x
__
We can find when the costs are the same by solving this system of equations. A way to do that is to subtract the second equation from the first:
(y) -(y) = (40 +0.13x) -(53 +0.08x)
0 = -13 +0.05x
Multiplying by 20 gives ...
0 = -260 +x
Adding 260, we have ...
x = 260
The plans cost the same for 260 miles of driving.
__
The cost of the plans for that distance is ...
y = 40 +0.13x = 40 +0.13(260) = 40 +33.80
y = 73.80
The cost when the two plans cost the same is $73.80.

Which linear inequality is represented by the graph? O y>2/3x-1/5 O y>3/2x+1/5 O y<2/3x+1/5 O y<3/2x-1/5
Answer:
Step-by-step explanation:
What you must do for this case first is to find the equation of the line.
We have then that by substituting the values of x = 0 and x = 3 we obtain:
y = 0.2
y = 2.2
Respectively.
So, the line is:
y = 2 / 3x + 1/5
Then, the points that satisfy the inequality are all those of the shaded region.
Answer:
The inequality is:
y ≤ 2 / 3x + 1/5

the question: “which trig. ratio woild you use to find the missing side?”
Answer:
Step-by-step explanation:
It's not the tangent. The tangent relates two sides neither of which is the hypotenuse, which you are given.
The trig ratio you would use is the one that relates the angle to the side opposite the angle and the hypotenuse.
That is the definition for the Sine.

Two parallel lines are cut by a transversal as shown below.
Suppose m<8=109. Find m<2 and m<3.
Answer:
measure 2 has to be 109 due to the alternate interior angles theorem. Measure 3 has to be 71 due to the supplementary angles theorem.
Angles 8 and 2 are alternate interior angles so they will be the same therefore,m∠2 and m∠3 will be 109° and 71° respectively.
What is an angle?An angle is a geometry in plane geometry that is created by 2 rays or lines that have an identical terminus.
The identical endpoint of the two rays—is known as the vertex.
Given two parallel lines a transversal.
Angles 8 and 2 are alternate interior angles.
m∠8 = m∠2
m∠2 = 108°
Now,m∠2 and m∠3 are supplementary angles.
Therefore,m∠3 = 180° - 108° = 71°
Hence "Angles 8 and 2 are alternate interior angles so they will be the same therefore,m∠2 and m∠3 will be 109° and 71° respectively".

Enter equations one at a time in order to send a line
through the coins to "capture" them.
Answer:
y = x + 3
y = 3x + 1
Step-by-step explanation:
This does it in two equations.
y = x + 3 and y = 3x + 1 equation will send 2 different lines through the coins to capture them
using the slope intercept equation,
y = mx + b
m = slope
b = y-intercept
let's pick 2 coordinate from the graph,
(-2, 1)(-1, 2)
m = 2 - 1 / -1 - (-2) = 1 / 1 = 1
1 = -2 + b
b = 3
Therefore,
y = x + 3
let check for another equation that will work for another line. Let's use the coordinates (-1, -2)(0, 1) to find slope.
Therefore,
m = 1 - (-2) / 0 - (-1) = 3 / 1 = 3
y = 3x + b
1 = 3(0) + b
b = 1
y = 3x + 1

Step-by-step explanation:
An architect designed a lobby wall to have an embedded circular clock. The equation (x – 4)^2 + (y – 7)^2 = 1, with units in meters, represents the location of the clock relative to the bottom left corner of the wall. How high above the ground is the center of the clock?
1 m
4 m
7 m
8 m
The height of the center of this circular clock (x - 4)² + (y - 7)² = 1, is 7 meters above the ground.
What are the types of equations of a circle?The equation for a circle has the generic form x² + y² + 2gx + 2fy + c = 0.
The standard equation of a circle is x² + y² = r².
The polar form of the equation of the circle is (rcosθ)² + (rsinθ)² = p².
We know the standard formula of a circle is x² + y² = r² centered at the origin.
Now, (x - h)² + (y - k)² = r² represents a circle centered at (h, k).
Given, The equation (x - 4)² + (y - 7)² = 1, with units in meters, represents the location of the clock relative to the bottom left corner of the wall.
Therefore, (4, 7) is the center of the clock in the x-y axis when the y-axis represents height so it is 7 meters above the ground.
