Based on the graph, which inequality is correct for a number that is to the left of -4?


a
−7 > −4
b
−6 −4
d
−4 < −9

Answer:

Step-by-step explanation:

∠A + ∠B = 180

where ∠A = 6x - 18

           ∠B = 14x + 38

first step is to solve for x:

6x - 18 + 14x + 38 = 180

6x + 14x = 180 + 18 - 38

20x = 160

x = 160 / 20

x = 8

now substitute x=8 into angle A

∠A = 6x - 18

∠A = 6(8) - 18

∠A = 30°

Answer:

x = - 6.22 or - 56/9

Step-by-step explanation:

Step 1:

34 + 12x = 3x - 22             Equation

Step 2:

12x = 3x - 56            Subtract 34 on both sides

Step 3:

9x = - 56          Subtract 3x on both sides

Step 4:

x = - 56 ÷ 9           Divide

Answer:

x = - 6.22

I think its D but I'm not that sure about it.

Step-by-step explanation:

Because three fifths less than two thirds, the slope of te climbing equipment at the playground is greater.

Answer:

A)

Step-by-step explanation:

A piece of climbing equipment at a playground is 6 feet high and extends 4 feet horizontally.

Therefore its slope = length of the equipment vertically / length of equipment horizontally

=  6/4 = 3/2 = 1.5

And, A piece of climbing equipment at a gym is 10 feet high and extends 6 feet horizontally.

Therefore slope, =  10/6 = 5/3=1.67 (approx)

Since, >

Therefore, Five-thirds greater-than three-halves, the slope of the climbing equipment at the gym is greater

(I finished the quiz and got it correct, it is A.)

Step-by-step explanation:

I dont know the answer exactly but to find the greatest common factor you have to find out like the numbers that go into the timetable your talking about like e.g a factor of 18 would be 6,3,2 etc. once you have done that between both of them then you have to find the same numbers between them. and that's the answer. hope it helped I'm not exactly good at explaining

Answer:

Part A  The 4th bubble y= -55x+1630

Part B 1630

Part C 55

Step-by-step explanation:

Part A Use slope to find answer. In this example, points (1,599) and (4,1430).

Next use equation y1-y2/x1-x2. In this example, 1599-1430/1-4  which equals 169/-3 and that equals -56.3333333333333333333333.  Since y= -55x+1630 is closer, choose that answer.

Part B use y intercept. The y intercept is 1630

Part C Use the slope -55. It decreases by 55.

Answer:

c. 2/3

Step-by-step explanation:

To find the slope, you subtract y^1 from y^2 and divide it by x^2 - x^1

Our y^2 is 7 and our y^1 is 1.

7-1 = 6

Our x^2 is 3 and our x^1 is -6.

3 - (-6) = 3+ 6 = 9

so our slope is 6/9, reduced is 2/3

Answer:

D)

Step-by-step explanation:

In slope-intercept form in order to find the perpendicular equation you change the sign and find its reciprocal.

So in the equation y= -3x+1, the opposite sign of - is + and the opposite of 3 is 1/3

The slope of the perpendicular line will be - 5/8.

What is Equation of line?

The equation of line in point-slope form passing through the points

(x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Given that;

Two points on the line are (2, 1) and (7, 9).

Now,

Since, We know that;

The slope of the line passing through the points (x₁ , y₁) and (x₂, y₂) is;

⇒ m = (y₂ - y₁) / (x₂ - x₁)

So, The slope of the line passing through the points (2, 1) and (7, 9) is;

⇒ m = (y₂ - y₁) / (x₂ - x₁)

⇒ m = (9 - 1) / (7 - 2)

⇒ m = 8 / 5

Since, The product of the slope of the perpendicular lines is - 1.

Here,  Line b is perpendicular to a.

So, The slope of the line b is,

m₂ = - (1/8/5)

    = - 5/8

Thus, The slope of the perpendicular line will be - 5/8.

Answer:

Always true

Step-by-step explanation:

Here, we want to evaluate if the given statement is true

The discriminant D can be calculated using the formula;

b^2 - 4ac

if D is greater than 0, then we will have only real roots

In a case where a and c are of opposite signs;

then -4ac will always give a positive value which can be added to b^2

This positive value will ensure that D is greater than zero and hence we can have only real roots

So this assertion is always true if a and c are of opposite signs

Answer:

its A (12-i)

Step-by-step explanation:

got it right on edge 2020

The complex number with modifying bar will be 12 - i so option (A) will be correct.

Complex numbers are helpful in finding the square root of negative numbers.

A complex number is the sum of a real number and an imaginary number.

The general form of a complex number is a + ib where the first part a called real and the ib is called imaginary.

If we solve x² + 1 = 0 ⇒ x = √(-1) which is called as iota(i).

Bar of complex number = replace i (iota) with - i (iota)

since z = 12 + i

So,

z bar = 12 - i

So 12 - i will be the correct answer to the given question.
