A Student Is Solving The Equation 4(x5)=6x7+2. Which Describes A First Step The Student Could Use To

Answers

Answer 1
first option.

you should usually distribute first. 4 times x would be 4x, and 4 times -5 is -20.
Answer 2

Answer:

4(x−5)=−6x−7+2

first step open bracket and add or subtract no.

4x-20=-6x-5

put common in each side

4x+6x=-5+20

10x=15

x=15/10=3/2

David invested $220 in an account paying an interest rate of 1.7%
compounded continuously. Assuming no deposits or withdrawals are
made, how much money, to the nearest ten dollars, would be in the
account after 10 years?

Answers

Answer:

260 dollars

Step-by-step explanation:

The amount after  10 years will be $260.

What is compound interest?

The interest that is calculated using both the principal and the interest that has accrued during the previous period is called compound interest. It differs from simple interest in that the principal is not taken into account when determining the interest for the subsequent period with simple interest. Compound interest is commonly abbreviated C.I. in mathematics.

Given amount invested = $220

rate = 1.7% compounded annually

time = 10 years

the amount is  given by

A = p[tex](1 + \frac{r}{n} )^{nt}[/tex]

r = 1.7% = 0.017

n = 1 for compounded annually

t = 10 years

p = $220

A = 220(1 + 0.017)¹⁰

A = $260.39

A = $260

Hence the amount is $260.

Given:

The table of values is:

0     8

4     13

8     18

To find:

The slope of the line that described by the data in the table.

Solution:

Consider any two points from the given table.

Let the two points are (0,8) and (4,13). So, the slope of the line is

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m=\dfrac{13-8}{4-0}[/tex]

Solve:
14x+y=7
Write your answer in the following format:
with no spaces.

Answers

Answer:

x = 7/10; y = 21/5

Step-by-step explanation:

y = 6x

4x + y = 7

Since the first equation is already solved for y, we can easily use the substitution method. We substitute 6x for y in the second equation and solve for x.

4x + y = 7

4x + 6x = 7

10x = 7

x = 7/10

Now we use the first equation and substitute 7/10 for x and solve for y.

y = 6x

y = 6 * 7/10

y = 42/10

y = 21/5

Answer: x = 7/10; y = 21/5

A, B, C and D are points on the circumference of the circle, centre O.
DOB is a straight line and angle DAC = 58°.
Find angle CDB.

Answers

Answer:

Angle CDB = 32

Step-by-step explanation:

Here, we want to find the measure of CDB

Mathematically;

angle DCB = 90

This is because angle at the center is twice the angle at the circumference

Also;

angle CAD = angle CBD = 58

This is because they are angles in the same segment

Furthermore;

CDB + 90 + 58 = 180

This is because sum of angles in a triangle is 180

CDB = 180-90-58

CDB = 32

Given A(5, –2), what are the coordinates of (T⟨−3, 4⟩∘ Rx-axis)(A)?

Answers

Answer:

not sure

Step-by-step explanation:

Following are the calculation to the given coordinates:

[tex]\to T (-2, 5)[/tex]

The y-axis reflection:Modify its abscissa's sign, i.e., the x-coordinate.Keep this ordinate, which would be the y-coordinate.

[tex]\to[/tex] (-2, 5) is the image (-2, -5).

Also, as a result, the coordinates of point T' after the Ry-axis are as follows: (2, 5).

Whenever a point is reflected throughout the x-axis, the x-coordinate is unchanged, but the "y-coordinate" is assumed to be the additional inversion.

[tex]\to[/tex] (-2, 5) is the image (-2, -5).

As a result, the coordinates of point T' after the Rx-axis are just as follows: (-2, -5)

A triangular road sign has a height of 3 feet and a base of 2.5 feet. How much larger in area is this sign than one with a height of 2.5 feet and a base of 3 feet?

Answers

Answer:

Not larger or smaller; the areas are the same

Step-by-step explanation:

Recall that the formula for the area of a triangle of base b and height h is

A = (1/2)(b)(h).

In the first case, h = 3 ft and b = 2.5 ft.  This results in an area of 3.75 ft^2.

In the second case, h = 2.5 ft and b = 3 ft.  The area is the same:  3.75 ft^2.

This is because A = (1/2)(b)(h) has the same value regardless of the order in which b and h  are used as multipliers.

There is no difference in the areas of the two signs.  The areas are the same.
