Answer:

The y intercept is (0,2) and the x intercept is (5,0)

Step-by-step explanation:

Find the y-intercept by letting x = 0

2(0) + 5y = 10

5y = 10

y = 2 Therefore, the y-intercept is (0, 2)

Find the x-intercept by letting y = 0

2x + 5(0) = 10

2x = 10

x = 5 Therefore, the x-intercept is (5, 0)

Answer:

[tex]y = \frac{1}{3}x +2[/tex]

Step-by-step explanation:

Given

Equation:

[tex]y = \frac{1}{3}x + 4[/tex]

[tex]Point: (-3,1)[/tex]

Required

Determine the equation of the point parallel to the given equation

First, we need to determine the slope of: [tex]y = \frac{1}{3}x + 4[/tex] using

[tex]y = mx + b[/tex]

Where m represents slope.

By comparison

[tex]m = \frac{1}{3}[/tex]

The equation of the point is calculated as thus:

[tex]y - y_1 = m(x - x_1)[/tex]

Where [tex](x_1,y_1) = (-3,1)[/tex]

So, we have:

[tex]y - y_1 = m(x - x_1)[/tex]

[tex]y - 1 = \frac{1}{3}(x - (-3))[/tex]

[tex]y - 1 = \frac{1}{3}(x +3)[/tex]

[tex]y - 1 = \frac{1}{3}x +1[/tex]

Solve for y

[tex]y = \frac{1}{3}x +1 +1[/tex]

[tex]y = \frac{1}{3}x +2[/tex]

Step-by-step explanation:

4 divided by 60=that

The provided arithmetic sequence adds up to 60.

The difference between every two successive terms in an arithmetic series is always the same. The number "a" is the first term, and "d" is the common difference between the sequence. The nth term of an arithmetic sequence is given by. aₙ = a + (n – 1)d

Given an arithmetic sequence 12, 14,16,18

The general formula for the Sum of arithmetic sequence:

Sn = n/2 [2a+(n−1)d]

where: n = the number of terms to be added.

a = the first term in the sequence.

d = the constant value between terms.

In our case,

a = 12

n = 4

and d = 14 - 12 = 2

thus

Sum = 4/2(2*12 + (4- 1 )2)

Sum = 2( 24 + 6)

Sum = 60

therefore, the Sum of the given Arithmetic sequence is 60.

This question was not properly written

Correct Question

A local bank charges $9 per month plus 2c per check. The credit union charges $7 per month plus 4cper check. How many checks should be written each month to make the credit union a better deal?

The credit union is a better deal when writing fewer checks per month

Answer:

Writing between 0 to 99 checks makes the credit union a better deal.

Step-by-step explanation:

Let the number of checks be represented by x

Note, 1 cent = $0.01

A local bank charges $9 per month plus 2c per check.

2c = $0.02

$9 + 0.02× x

= 9 + 0.02x

The credit union charges $7 per month plus 4c per check.

4c = $0.04

= $7 + 0.04 × x

= 7 + 0.04x

The credit union is a better deal when writing fewer checks per month

Hence:

Credit union < Local bank

7 + 0.04x < 9 + 0.02x

Collect like terms

0.04x - 0.02x < 9 - 7

0.02x < 2

x < 2/0.02

x < 100 checks

Hence, writing less than 100 checks (i.e writing between 0 to 99 checks) makes the credit union a better deal.

Step-by-step explanation:

Answer: 990

Step-by-step explanation:

SA = 2LH + 2LW + 2WH

SA= 2(25•10) + 2(25•7) + 2(7•10)

SA= 990

The surface area of a rectangular solid will be 990 square feet.

Let the prism with a length of L, a width of W, and a height of H. Then the surface area of the prism is given as

SA = 2(LW + WH + HL)

We have length 25 feet, width 7 feet, and height 10 feet.

SA = 2(25 x 7 + 7 x 10 + 10 x 25)

SA = 2(175 + 70 + 250)

SA = 2(495)

SA = 990 square feet

The answer is 3

Step-by-step explanation:

To find the quotient of 8 divided by 1/3 multiply 8 by

8/1 divided by 1/3

8 x 3

-------

1 x 1

=

24/1

=

24

The quotient of 8 divided by one-third is same as multiply 8 by 3.

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.

For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

We have to given that;

The quotient of 8 divided by one-third.

Now, We get;

The quotient of 8 divided by one-third.

⇒ 8 ÷ 1/3

⇒ 8 × 3

Thus, It is clear from the above steps that dividing 8 by 1/3 is equivalent to multiplying 8 by 3.

Therefore, Multiplying 8 by 3 will give the same quotient.

Answer:

A) There is a rational relationship, B) Given ratio is not an integer.

Step-by-step explanation:

A) Is the relationship in Part A rational or irrational? Justifty your answer.

From Mathematics we remember that a rational number can formed by dividing a natural number by another natural number. Since Kara and Nathan had two natural numbers {32, 40} as their times of participation in the maze race, ratio between those times can be considered a rational number.

Hence, there is a rational relationship.

B) Can the times for each be written as integers?

The times represents the ratio of the upper number (40) to the lower number (32), the "times" can be written as integer if and only if denominator is equal to 1 after simplifying the ratio. That is:

[tex]x = \frac{40}{32}[/tex]

[tex]x = \frac{20}{16}[/tex]

[tex]x = \frac{10}{8}[/tex]

[tex]x = \frac{5}{4}[/tex]

In consequence, this ratio does not represent an integer. ([tex]1.25=\frac{5}{4}[/tex])

Answer:

A possiable answer to solve this could be E is 86 and F is 66

Step-by-step explanation:

All triangles have a 180 degree to them. I just subtracted 28 from 180. Diveded that by 2 then gave one ten degrees more and the other has ten degrees less

The measure of the angle E will be 90° and the measure of the angle F will be 62°.

A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.

The triangle DEF is a right triangle and the of angle D is 28°.

In a right-angle triangle, one angle will be 90°.

If the measure of angle E is greater than the measure of angle F. Then the angle E will be 90°. Then the measure of the angle F will be given as,

We know that angle D and angle F are complementary. Then the equation is given as,

∠F + ∠D = 90°

∠F + 28° = 90°

∠F = 62°

The measure of the angle E will be 90° and the measure of the angle F will be 62°.
