Answer:

f(x)=-4x+14

Step-by-step explanation:

These are the way to convert from vertex to stand form

Expand the expression in the bracket: y = a*(x² - 2*h*x + h²) + k ;

Multiply the terms in the parenthesis by a : y = a*x² - 2*a*h*x + a*h² + k ;

The equivalent expression will be :

[tex] \frac{4y}{9} - \frac{2y}{3} = 10 \\ = > \frac{4y - 6y}{9} = 10 \\ = > \frac{ - 2y}{9} = 10 \\ = > y = 10 \times \frac{9}{ - 2} \\ = > y = - 5 \times 9 \\ = > y = - 45[/tex]

Answer:

C: Xint = 2, Yint. = -7

Step-by-step explanation:

Given the equation, 2x - 7y = -14:

The y-intercept is the point on the graph where it crosses the y-axis, and has coordinates (0, b). It is also the value of y when x = 0.  To solve for the y-intercept, set x = 0:

2x - 7y = -14

2(0) - 7y = -14

0 - 7y = -14

-7y = -14

Divide both sides by -7 to solve for y:

-7y/-7 = -14/-7

y = 2

Therefore, the y-intercept = 2.

Next, the x-intercept is the point on the graph where it crosses the x-axis, and has coordinates, (a, 0). To find the x-intercept, set y = 0 and substitute into the given equation:

2x - 7y = -14

2x - 7(0) = -14

2x - 0 = -14

2x = -14

Divide both sides by 2 to solve for x:

2x/2 = -14/2

x = -7

x-intercept = -7.

Therefore, the correct answer is C: Xint = 2, Yint. = -7

Answer:

inverse of 5/42 = -42/5 = -8 2/5 = -8.4

inverse of 15/42 is flipped -42/5 = -2.8

The decimal steps are;

if 5/42 then show -1/1 = 5/42 = 42/5 = 8 2/5

= 8.4

if 15/42 then -1/1  ÷15/42  = -14/5

=  -2.8

Step-by-step explanation:

if the question was 15/42 then we divide by -1 /15/42 = -42 / 15

so we can divide all by -1 or -1/1

The calculation steps are ;

-1/1÷  15/42  

=  -1/1×42/15

= -1 × 42 /  1 × 15

=  -42/15

The decimal steps are;

if 5/42 then show -1/1 = 5/42 = 42/5 = 8 2/5

= -8.4

if 15/42 then -1/1  ÷15/42  =–14/5

=  –2.8

Option 1. The equation tells us that line is going through the x-axis at (2,0) in a straight line.

Answer:

[tex]2y + 8 = 4 \\ 2y = 4 - 8 \\ 2y = - 4 \\ y = \frac{ - 4}{2} \\ y = - 2 \\ y + 1 = - 2 + 1 \\ \boxed{y + 1 = - 1}[/tex]

Therefore, the value of (y+1) is -1

Answer:

Continuous graph:

- The height of a plant as it grows

- Amount of fuel and distance traveled.

Discrete graph:

- Number of students per teacher

- Amount of chairs for each table

Step-by-step explanation:

In mathematics "discrete" means specific points that do not possess a continuous line but only the plotting of points above certain integer values. On the other hand, the word "continuous" in mathematics would be a graph that has a constant smooth line that lacks jumps between values and sometimes decimal numbers.

"The number of students per teacher" would be discrete as the amount of students per teacher would be a fixed integer value.

"The height of a plant as it grows" would be continuous as the height of the plants increases the longer it grows. This would be represented by a straight continuous line.

"Amount of fuel and distance traveled" would be continuous as the amount of fuel used correlates with the distance traveled, which can be represented with a continuous line.

"Amount of chairs for each table" would be discrete as it would be a set integer value for the amount of chairs at each table, not a continuous line.

Answer:

line n

Step-by-step explanation:

Line 'n' is the segment bisector.

We have a line segment XY given in figure.

We have to identify its segment bisector.

A segment bisector divides a line segment into two equal parts.

According to the question, we have -

Line Segment XY and its Mid - Point M. It can be seen that the line 'n' is the segment bisector of the segment XY.

Hence, line 'n' is the segment bisector.

Answer:

417,808

Step-by-step explanation:

original weight = x

A 27% decrease is the same as multiplying by 0.73

27% = 0.27

1 - 0.27 = 0.73

x × 0.73 = 305,000kg

To find x, divide 305,000kg by 0.73

305,000 ÷ 0.73 = 417,808.2192 ≈ 417,808

Answer:

In geometry, a linear pair of angles is a pair of adjacent angles formed when two lines intersect each other. The linear pair of angles are always supplementary as they form on a straight line. In other words, the sum of two angles in a linear pair is always 180 degrees.
