Answer:

-3/4x

Step-by-step explanation:

Down 3, right 4. We know it's negative because it's declining, and going down till you reach the x-coordinate of the point gives us -3, and going right 4 units to the location of the point.

Answer:

The answer you selected is correct.

Step-by-step explanation:

The answer has to be greater than 0 so the bottom graph is correct.

The graph that represents the solution set for the quadratic inequality is option (C) is the correct answer.

An inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions. It is the condition of being unequal. It is used most often to compare two numbers on the number line by their size.

For the given situation,

The quadratic inequality is x^2 + 2x + 1 > 0

[tex]x^2 + 2x + 1 > 0[/tex]

⇒ [tex](x+1)(x+1) > 0[/tex]

Plot this function on the graph as shown below.

From the graph, the function extends in both positive and negative direction at x = -1.

On number line, we can denote it as x = -1 and extends up to infinity on both sides.

Hence we can conclude that the graph that represents the solution set for the quadratic inequality is option (C) is the correct answer.

We just have to multiply not cross multiply,

10/18

Now, divide the equation

5/9 will be ur answer

Answer:

No

Step-by-step explanation:

[tex]\frac{2}{3} \frac{5}{6}[/tex]

2 goes into 6 3 times so it would be the same as 1 going into 3 3 times.

[tex]\frac{1}{3} \frac{5}{3}[/tex]

Since 3 doesn't go into 5 at all (and by that I mean a whole number) you don't change it.

Multiplying 1/3 and 5/3, you would get 5/9.

Multiplying 2/3 and 5/6, you would get 10/18, which simplifies to 5/9.

That is kind of how cross multiplying works.

Answer:

One solution

Step-by-step explanation:

The slope and y-intercept is different on both sides

The given equation has one solution which is the variable x = -27.

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that is equal.

The equation is given in the question,

0.4(5x – 15) = 2.5(x+3)

Multiply both sides by 10

0.4(5x – 15) × 10=25(x+3) × 10

Refine

4(5x–15) =2.5(x+3)

Expand 4(5x-15): 20x-60

Expand 25(x+3): 25x+75

20x-60 = 25x+75

Add 60 to both sides

20x-60+60 = 25x+75 +60

Simplify the above equation,

20x=25x+135

Subtract 25x from both sides

20x-25x = 25x+135-25x

-5x  = -135

Divide both sides by -5

-5x / -5 = -135/5

x = -27

Therefore, the given equation has one solution which is the variable x = -27.

Answer:

C

Step-by-step explanation:

We have the compound inequality:

[tex]5x+7\leq-3\text{ or } 3x-4\geq11[/tex]

We will solve each inequality individually and then combine them at the end.

For the first inequality, we have:

[tex]5x+7\leq-3[/tex]

Subtract 7 from both sides:

[tex]5x\leq-10[/tex]

Divide both sides by 5:

[tex]x\leq-2[/tex]

For the second inequality, we have:

[tex]3x-4\geq11[/tex]

Add 4 to both sides:

[tex]3x\geq15[/tex]

Divide both sides by 3:

[tex]x\geq5[/tex]

Since our original inequality was an “OR,” our solution set is also an “OR.”

Hence, our solution is:

[tex]x\leq-2\text{ or } x\geq5[/tex]

Thus, our answer is C.

Answer:

D, neither

Step-by-step explanation:

If you want to solve this through elimination, just substitute the given points in each choice. (a,b) → (x,y)

In a coordinate the first number is the x value, and the second is the y.

All you have to do is substitute the indicated values given in the coordinate into the point slope equation, and determine whether or not the equation is true. If the equation is true (for example 1 = 1) the order pair IS a solution. If the equation is false (for example 1 = 2), than the ordered pair IS NOT a solution.

If you want to look at this linear equation solving for the quantity y, then use slope intercept.

Choice 1 is incorrect because (5,4) →

y - 4 = 7(x - 6) → (4) - 4 = 7((5) - 6) →

0 = 7(-1) → 0 = -7 (0 is never equal to -7) ; contradictory

Choice 2 is incorrect because (6,5) →

y - 4 = 7(x - 6) → (5) - 4 = 7((6) - 6) →

1 = 7(0) → 1 = 0 (1 is never equal to 0) ; contradictory

Therefore Choice 3 must be incorrect as well because neither of these two pairs are solutions, so combining two pairs that do not satisfy the equation does not make it any more true.

Since Choice 4 is the remaining choice, it must be the correct answer.

The points that fit on this line are given by the slope intercept equation: y = 7x - 3.

To convert point slope form to slope intercept form, first distribute everything in the parenthesis. Then remove all the terms besides y from the left side of the equation to the right:

y - 4 = 7(x - 6) → y - 4 = 7(x) + 7(-6) →

y - 4 = 7x - 42 → y - 4 + 4 = 7x - 42 + 4 →

y = 7x - 38.

Just substitute the x or y value into the equation, and find the corresponding y or x variable that fits the line.

Answer - the answer should be: -3x+4

down below is how i did it,

Step-by-step explanation:

use the formula mx+b=y

y is f(x)

m = -3

x = x

b = 4

so,

mx+b is -3x+4

A linear function is the function of a straight line.

The linear function is: [tex]\mathbf{f(x) = -3x + 4}[/tex]

The given parameters are:

[tex]\mathbf{f(2) =-2}[/tex]

[tex]\mathbf{f(1) =1}[/tex]

Calculate the slope (m)

[tex]\mathbf{m = \frac{f(b) - f(a)}{b -a}}[/tex]

So, we have:

[tex]\mathbf{m = \frac{-2-1}{2 -1}}[/tex]

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

[tex]\mathbf{m = -3}[/tex]

The linear function is then calculated as:

[tex]\mathbf{y = m(x - x_1) + y_1}[/tex]

This gives

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

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

[tex]\mathbf{y = -3x + 4}[/tex]

Rewrite as:

[tex]\mathbf{f(x) = -3x + 4}[/tex]

Hence, the linear function is: [tex]\mathbf{f(x) = -3x + 4}[/tex]

Answer:

joe 20+ 4x

Step-by-step explanation:

Answer:

x= 33

y= 106

Step-by-step explanation:

4x-58=74

+58 +58

4x=132

4x/4=132/4

x=33

If two parallel lines intersect another two parallel lines then all corresponding angles will be the same thus the value of y is 106° and x is 33°.

Two lines in the same plane that are equally spaced apart and never cross each other are said two lines in the same plane that are equally spaced apart and never cross each other to be parallel lines.

It is known that the If two parallel lines intersect another two parallel lines then all corresponding angles will be the same.

Therefore, 74 = 4x - 58

4x = 132

x = 33.

Since 74° and the adjacent angle of y° are made by two parallel lines on the same line thus both will also same.

The adjacent angle of y = 74°

Since,  adjacent angle + y = 180°

y = 180 - 74 = 106°.

Hence "If two parallel lines intersect another two parallel lines then all corresponding angles will be the same thus the value of y is 106° and x is 33°".
