6x -4=-4+6x
can i get some help with this question
Answers
Answer:
infinite solutions
Step-by-step explanation:
At first, we try to isolate the x, but adding 4 to -4 on both sides. Both sides have a -4 so it cancels out on both sides of the equation. Similarly, both sides also have a positve 6x, so when we subtract 6x from 6x we get 0. After simplification, we get x = x; x can be any number [ex. 1=1, 2=2, 3=3,etc.], therefore any number can fit into this equation
6x - 4 = -4 + 6x
6x - 4 + 4 = -4 + 4 +6x
6x = 6x
x = x

infinite solutions

Which lateral face has the largest area, the bottom one, left one, or diagonal one? What is its area?
Answers
Answer:
LSA of a cube = 100 in²
Explanation:
Let the area of the cube be a.
Given the following data;
a = 5 in²
To find the lateral surface area;
We know that a cube has four faces and as such the lateral surface area would be the area of the four faces.
Lateral surface area (LSA) of a cube = 4a²
Substituting into the equation, we have;
LSA of a cube = 4*5²
LSA of a cube = 4*25
LSA of a cube = 100 in²
Therefore, the lateral surface area of the package is 100 square inches.
THe Left one
The bottom and the left lateral face have the largest area.
The area of the prism is 96 cm³.
What is a prism?A prism is a three-dimensional object.
There are triangular prism and rectangular prism.
We have,
The bottom one:
Lateral area.
= 12 x 4
= 48 cm²
The left one:
Lateral area.
= 12 x 4
= 48 cm²
The diagonal one:
Lateral area.
= 1/2 x 4 x 4
= 8 cm²
Now,
Area.
= ( 1/2 x 4 x 4 ) x 12
= 8 x 12
= 96 cm³
Thus,
The bottom and the left lateral face have the largest area.
The area of the prism is 96 cm³.

Shelley wants to purchase a cell phone package, which includes a free phone. The cost of the package is $0.10 per minute, for the number of minutes she uses the phone, plus a base rate of $89.00.
Answers
Answer:
The function would be linear because the rate of change is constant.
Step-by-step explanation:
Given
[tex]Base= \$89.00[/tex]
[tex]Rate = \$0.10[/tex] per minute
See attachment for complete question and options
First, we write the function that calculates the cost (C(t)) for t minutes.
This is calculated as:
[tex]Cost = Base + Rate * t[/tex]
[tex]C(t) = 89.00 + 0.10 * t[/tex]
[tex]C(t) = 89.00 + 0.10t[/tex]
Rewrite as:
[tex]C(t) = 0.10t + 89.00[/tex]
A function that has the above format is referred to as a linear function which has the general format
[tex]f(x) = mx + b[/tex]
Where
m represents the slope/rate and it is constant

Given that ABCD is a parallelogram with diagonals intersecting at M. Segment PQ is drawn such that P lies on AB and Q lies on DC and it passes through M. Prove that PM is congruent to QM.
Answers
Answer:
we thus have enough informnation to prove that the two triangles are congruent. Because of thism, one side of the triangles, Pm which is the congruent side to that of PQ must be equal as well and
PM = QM
Step-by-step explanation:
because it's a parrallelogram, Ad = BC and AB = DC.
P passes through both AB and DC on a diagonal, angles created by P have oppoiste exterior angles of eachother.
the diagonals of AC create congruent angles at DMC and AMB and because P is cutting through them, the angles P cuts at DMQ and QMC are equal to that of AMP and PMB
that being said, we now see that the angles of APM triangle and AMC triangol are equal and because the diagonal of BD is is being cut by AC, which AD is parralel to BC and AB to Dc, we know now that lines AM and MC are congruent
we thus have enough informnation to prove that the two triangles are congruent. Because of thism, one side of the triangles, Pm which is the congruent side to that of PQ must be equal as well and
thus PM = QM
The alternate interior angles formed by the parallel sides and a common
transversal are equal, such that ΔPBM and ΔQDM are congruent.
Correct response;
PM is congruent to QM by CPCTCHow is the congruency of the segments determined?The two column proof is presented as follows;
