If the equation of a line in standard form is 3x + 2y = 18, then the x-intercept is 6 and the y-intercept is 9.
True
False

Answer:

-509

Step-by-step explanation:

h(t) = -16t² + 38t + 9

h(7) = - 16(49) + 38(7) + 9

h(7) = -784 + 266 + 9

h(7) = -509

Solution:

It should be noted:

To find h(7), let's find "t" by comparing h(7) and h(t).

Compare h(7) and h(t):

Now, find h(7) by substituting the value of t into the equation.

Substitute the value of t into the equation:

Thus, h(7) is -509.

The total area of the figure = area of rectangle + area of triangle = 241 sq. m.

Thus:

Total area of the figure = area of rectangle + area of triangle

= length × width + 1/2 × base × height

Total area of the figure = 12 × 9 + 1/2 × 19 × 14

Total area of the figure = 241 sq. m.

Answer:

x = 4

Step-by-step explanation:

it's important to keep in mind that you can do anything to an equation as long as you do it to both sides, and it will still be equal.

2x + 5 = 13

subtract 5 from both sides of the equation

2x + 5 -5 = 13 - 5

2x = 13 -5

2x = 8

divide both sides of the equation by 2

2x/2 = 8/2

x = 4

The value of x for the equation 2x + 5 = 13 is x = 4.

Given that:

There is an equation in x which is given as,

2x + 5 = 13

It is required to find the value of x.

That is, solve the equation.

It is required to get the equation in such a way that x is on one side and a constant on the other side.

2x + 5 = 13

Subtract both sides by 5.

2x = 8

Divide both sides by 2.

x = 4

Hence the value of x is 4.

Answer: 1.8

Step-by-step explanation:

(-18-(-9))/(12-7)=-9/5

Answer:

(for the second one)

y = 4x + 10

solution:

so first you have to find the slope, there is an equation for it. it is y2 - y1/ x2 - x1 or just y1 - y2/ x1 - x2 . so input the easiest points. id say f(0) and f(1)

so it will look like

2 - 6/0 - 1

-4/-1

4

so you can now write the equation as

y = 4x + b

now you have to find the y-intercept so input a point. i dont think you should input a point you used to find the slope because you could have made a mistake calculating so lets input f(2)

sooo

18 = 4(2) + b

18 = 8 + b

b = 10

so the function for the second one is y = 4x + 10

The total remaining bank balance in the account of Omar after reducing all the debit and adding paycheck is $761.25

The money which is paid from an account is called the debit amount and the money which is paid into an account is called the credit amount.

To know the remaining balance of account, all the debit amount is subtracted from it and all the credit amount is added into it.

The table for the Omar's transaction is attached below. The data given in the table is,

The initial balance is $219.80, and a pay check of $1015.50 is credited in his account. Thus, the total balance in his account without any debit is,

[tex]A_i=1015.50+219.80\\A_i=1253.30[/tex]

The total amount debited from the account of Omar is,

[tex]A_d=15.20+425.00+22.30+26.70\\A_d=474.05[/tex]

Thus, the total remaining amount in his account is,

[tex]A=1253.3-474.05\\A=761.25[/tex]

Hence, the total remaining bank balance in the account of Omar after reducing all the debit and adding paycheck is $761.25

Answer: The cost of a single group lesson is $5 and a single private lesson is $25

Step-by-step explanation:

Let the cost of a single group lesson be y.

Let the cost of a single private lesson be z.

A karate school offers a package of 12 group lessons and 2 private lessons for $110. This can be written as:

12y + 2z = 110 ..... equation i

It also offers a package of 10 group lessons and 3 private lessons for $125. This can be written as:

10y + 3z = 125 ...... equation ii

Combining equation i and ii

12y + 2z = 110 ..... equation i

10y + 3z = 125 ...... equation ii

12y + 2z = 110 × (3)

10y + 3z = 125 × (2)

36y + 6z = 330 ....... equation iii

20y + 6z = 250 ...... equation iv

Subtract equation iv from iii

16y = 80

y = 80/16

y = 5

From equation ii

10y + 3z = 125

10(5) + 3z = 125

50 + 3z = 125

3z = 125 - 50

3z = 75

z = 75/3

z = 25

The cost of a single group lesson is $5 and a single private lesson is $25

A group lesson costs = $5.

A private lesson costs = $25.

Let a group lesson costs = $x

A private lesson costs = $y.

According to the question:

12x + 2y = 110

10x + 3y = 125

Solving them we get x = 5, y = 25

The estimated probability of a success is  3/5 or 60%.

Probability refers to a possibility that deals with the occurrence of random events.

The probability of all the events occurring need to be 1.

The formula of probability is defined as the ratio of a number of favorable outcomes to the total number of outcomes.

We are given that randomly generated list of integers from 0 to 4 is being used to simulate an event with the numbers 1, 2, and 3 representing a success.

d = log₂p represents a logarithmic function, The expression log₂(10) tells us when the population reaches 10,000 and the equation 7 = log₂(128) tells us that the population reaches 128,000 in 7 days.

An exponential function is in the form:

y = abˣ

Where a is the initial value of y and b is the multiplication factor.

C. a rotation 180° clockwise about the origin followed by a reflection across the line y = x

Step-by-step explanation:

Let us assume that the coordinate of A in triangle ABC is A(x, y)

A) If there is a reflection across line y = x, the new coordinate is at A'(y, x).

If a reflection across the line y = -x is then followed, the new coordinate is at A"(-x, -y)

B) If there is a reflection across line x axis, the new coordinate is at A'(x, -y).

If a reflection across the line y axis is then done, the new coordinate is at

A"(-x, -y)

C) If there is a rotation 180° clockwise about the origin, the new coordinate is at A'(-x, -y).

If a reflection across the line y = x is then followed, the new coordinate is at A"(-y, -x)

D) B) If there is a reflection across line y axis, the new coordinate is at A'(-x, y).
