Step-by-step explanation:

a, what is the equation of the line that goes through these points in Slope-intercept Form?  

If two lines are parallel, their slopes are equal.  Thus the new line has the same slope as does the old one:  m = -3.  We adapt the slope-intercept form y = mx + b to 5 = (-3)(2) + b and find that b = -11.  Then the desired equation is y = -3x - 11.  This is in slope-intercept form.

b. What is the x-intercept?  Start with the above y = -3x - 11.  Set y = 0 and solve the result, 0 = -3x - 11, for x:  x = -11/3.  Then the x-intercept is (-11/3, 0); this is the point at which the graph crosses the x-axis.

c. What is the y-intercept:  Set x = 0 in the above equation.  We get y = -11.

The y-intercept is thus (0, -11).

Answer:

Step-by-step explanation:

did the homework and this was the right answer.

The vertex form of the function g will be;

⇒ g (x) = - 5x² - 3

What is Translation?

A transformation that occurs when a figure is moved from one location to another location without changing its size or shape is called translation.

Given that;

The parent function is,

⇒ f (x) = x²

Now,

After the reflection across the x - axis, we get;

f (x) = - f (x)

Thus, The function is,

g (x) = - x²

And, Vertically stretched by a factor of 5, we get;

g (x) = - 5x²

And, Translated 3 units down, we get;

g (x) = - 5x² - 3

Thus, The vertex form of the function g will be;

⇒ g (x) = - 5x² - 3

Answer:

  (x, y) = (4, 1)

Step-by-step explanation:

Step 1. Look for an equation that has a coefficient of 1 or -1 for one of the variables. Here, that is the first equation, which has a y-coefficient of -1.

Step 2. If you found such an equation, solve for the variable.

  y = 2x -7

Step 3. Use that expression for the variable to substitute into the other equation.

  3x -2(2x -7) = 10

Step 4. Solve the resulting equation in the usual way.

  3x -4x +14 = 10 . . . . . eliminate parentheses

  -x +14 = 10 . . . . . . . collect terms

  4 = x  . . . . . . . . . separate variable terms and constant terms. Here, we added x-10 to both sides.

If the variable has a coefficient that is not 1, divide both sides by that coefficient.

Now, you can use this value in the expression for y that we found above.

  y = 2(4) -7 = 1

The solution is (x, y) = (4, 1).

The value of the given expression is 87.46.

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

The given expression will be solved as below:-

E = 84-( -√12)

Two negative signs cancel out into a positive sign

E =84 + √12

84 plus the square root of 12. The square root of 12 is 3.5 or 3.46.

E = 84 + 3.46

E = 87.46

Answer:

x = 12

Step-by-step explanation:

The angle vertically opposite to ∠ 2 is corresponding to ∠ 1 and congruent, so

∠ 2 = ∠ 1 , substitute values

2(5x - 3) = 9x + 6 ← distribute parenthesis on left side

10x - 6 = 9x + 6 ( subtract 9x from both sides )

x - 6 = 6 ( add 6 to both sides )

Answer:

Width <= 5 and length <= 9

Step-by-step explanation:

Width: x

Length: x+4

2x + 2(x+4) <= 28 (less or equal)

2x + 2x + 8 <= 28

4x <= 28-8

x <= 20/4

x <= 5

If  length of a rectangle is 4 cm longer than the width the perimeter is no more than 28 cm. Then length of rectangle is lesser than or equal to 5 and width is lesser than or equal to 9.

The area of Rectangle is length times of width.

Let us consider width of rectangle be w= x cm

From given  length of a rectangle is 4 cm longer than the width

l=(x+4)cm

The perimeter of rectangle =2(Length+width)

=2(x+x+4)

=2(2x+4)

=4x+8

the perimeter is no more than 28 cm

4x+8≤28

Subtract 8 on both sides

4x≤20

Divide both sides by 4

x≤5

Hence  length of rectangle is lesser than or equal to 5 and width is lesser than or equal to 9.

Answer:

8x + 6 = 2 * (5x - 2)

x = 5

OP = 46

Step-by-step explanation:

The Triangle Midsegment Theorem

A midsegment connecting two sides of a triangle is parallel to the third side and is half as long.

So,  PO =  2 * SQ

8x + 6 = 2 * (5x - 2)

8x + 6 = 10x - 4

6 + 4 = 10x - 8x

10 = 2x

x = 5

OP = 8x + 6

= 8 * 5 + 6

= 40 + 6

The solution to given system of equations are x = -1, y = 1 and z = 5 which is determined by the substitution method.

The given system of equations below as

4x – 2y + 3z = 9  ....(i)

x - 2y = -3             ....(ii)

2x + 3y = 1            ....(iii)

By equation (ii) and solving for x to get

x - 2y = -3

x = 2y - 3    ....(iv)

Substitute the value of x = 2y - 3 in the equation (iii)

2(2y - 3) + 3y = 1

4y - 6 + 3y = 1

7y = 7

y = 1

Substitute the value of y = 1 in equation (iv) to get,

x = 2(1) - 3

x = -1

Substitute the values of x = -1 and y = 1 in equation (i), and solve for z

4(-1) – 2(1) + 3z = 9

-4 - 2 + 3z = 9

3z = 15

z = 5

Therefore, the solution to given system of equation are x = -1, y = 1 and z = 5.

Answer:

The answer is 6.

Step-by-step explanation:

If there are 270 students going on the trip and there would be a teacher for every 45 students you would have to divide.

You would divide 270 ÷ 45 = 6.

The required number of teachers for the trip is 12.

Given that,
A school was taking a field trip. The principal wanted 2 teachers for every 45 students. If 270 students will be attending the trip how many teachers must chaperone is to be determined.

Proportionality is defined as between two or more groups of values, and how these values are related to each other in the sense that are they directly proportional or inversely proportional to each other.

Let the number of teachers is x and the number of students is y, which are directly proportional to each other
y ∝ x
y = km
where k is the constant proportionality.

at y = 45 x = 2
45 = K * 2
K = 45 / 2
Now,
y = 45/2 x
Now for y =270
270 = 45 / 2 x
x = 270 * 2 / 45
x = 12

Thus, the required number of teachers for the trip is 12.
