Question 1 options:

A)

3.5

B)

C)

–3.5

D)

–1.13

Answer:

Step-by-step explanation:

step 1: Absolute value inequality entered

     |14c+5| > 7

step 2: Clear the absolute-value bars by splitting the equation into its two cases, one for the Positive case and the other for the Negative case.

The Absolute Value term is |14c+5|

For the Negative case we'll use -(14c+5)

For the Positive case we'll use (14c+5)

step 3:  -(14c+5) > 7

    Multiply

     -14c-5 > 7

    Rearrange and Add up

     -14c > 12

    Divide both sides by 14

     -c > (6/7)

    Multiply both sides by (-1)

    Remember to flip the inequality sign

     c < -(6/7)

    Which is the solution for the Negative Case

step 4:

(14c+5) > 7

    Rearrange and Add up

     14c > 2

    Divide both sides by 14

     c > (1/7)

    Which is the solution for the Positive Case

c < -6/7

 c > 1/7

Answer: 7+21

Step-by-step explanation:

It should be noted that the ratio in simplest form of 45 to 9 is 5:1.

It should be noted that a ratio and fraction are simply used in mathematics to compare one thing with something else.

In this case, it should be noted that we want to write the ratio as a fraction in simplest form, with whole numbers in the numerator and denominator 45 to 9.

Therefore, the ratio of 45 to 9 will be:

= 45 / 9

= 5:1

Therefore, it should be noted that the ratio in simplest form of 45 to 9 is 5:1.

4/9 is not an Extraneous solution of the equation

Given Equation is √x+ 2√x=2.

On Squaring both the side of the equation, we get

(√x+ 2√x)² = 2²

Using the identity (a + b)² = a² + b² + 2ab on the left hand side of the equation

(√x)² + (2√x)² + 2(✓x)(2✓x) = 4

x + 4x + 4x = 4

9x = 4

x = 4/9

Check for Extraneous Solutions

Putting the value of x = 4/9 in the original equation √x+ 2√x=2, we get

✓(4/9) + 2(✓4/9) = 2

2/3 + 2(2/3) = 2

2/3 + 4/3 = 2

The slope intercept equation for a line that passes through the points (-2,4) and (3,-5) is y = -9/5x ₊ 2/5.

Given the points are:

P₁ = (-2,4) = (x₁ , y₁)

P₂ = (3,-5) = (x₂ , y₂)

Therefore, the equation of the line that passes through the above points is:

y = mx ₊ b , Will be the equation to arrive to at the very end, but we need m & b, the slope and the y-intercept.

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

= ( -5 - 4 ) / ( 3 - ( -2) ) = -9 / 5

∴ m = - 9/5

Using either P₁ or P₂, plug in one of their respective x- and y-values into:

y = -9/5 x + b

substitute (3,-5)

₋5 = (₋9/5)(3) ₊ b

₋5 = ₋27/5 ₊ b

₋5₊27/5 = b

₋ 25 ₊ 27/5 = b

b = 2/5

slope intercept equation:

y = mx ₊ b

y = -9/5x ₊ 2/5

Therefore, y = -9/5x ₊ 2/5 is the equation of the line that passes through both points (-2, 4) and (3, -5).

The evaluation of the expression given in surd form is 6.

Surds are expressions that use a root symbol, such as a square root, or another root symbol. Since the decimals of irrational numbers do not finish or recur, they cannot be expressed accurately in decimal form, hence surds are used instead.

Surds, in mathematics, are square root values that cannot be factored into a whole number or an integer. Numbers that are surds are irrational numbers.

The linear equation of the table is y = 5x + 2.

when x = 20, y = 102

when y = 42, x = 8

Linear equation can be represented in slope intercept form as follows;

y = mx + b

where

Therefore,

m = 17 - 12 / 3 - 2

m = 5 / 1

m = 5

Therefore, let's find the y-intercept using (2, 12)

y = 5x + b

12 = 5(2) + b

12 = 10 + b

b = 12 - 10

b = 2

Therefore, the linear equation is y = 5x + 2.

when x = 20

y = 5(20) + 2 = 100 + 2

y = 102

when y = 42

42 = 5x + 2

42 - 2 = 5x

5x = 40

x = 40 / 5

It should be noted that the main distinction between continuous and discrete data is that the former has a finite value that can be counted while the latter has an endless number of possible values that can be measured.

A count involving integers is referred to as discrete data because there are a finite number of possible values. This kind of data cannot be separated into separate components. Discrete data consists of discrete variables that are non-negative, countable, and finite.

The value of x will be 12 and the angle measurements of ∠A and ∠B is 45°.

Parallel lines are those lines that are equidistant from each other and never meet, no matter how much they may be extended in either directions.

Given is a set of two lines parallel to each other intersected by a line. From the question, we can write -

∠A = 5x - 15

∠B = 2x + 21

Refer to the image attached.

From the figure it can be seen that -

∠B = ∠TRO = 2x + 21             [Vertically opposite angles are equal]

∠TRO = ∠POR = 2x + 21       [Alternate interior angles are equal]

∠A = ∠POR = 2x + 21            [Vertically opposite angles are equal]

It is given that

∠A = ∠B

5x - 15 = 2x + 21

3x = 21 + 15

3x = 36

x = 12

Then -

∠A = 2x + 21 = 24 + 21 = 45°

∠B = ∠A = 45°

Therefore, the value of x will be 12 and the angle measurements of ∠A and ∠B is 45°

The figure must be true if Ray CE seems to be the angle bisector of ZACD, as stated in the supplied statement.

∠ACE = ∠DCB.

The line or line segment that divides an angle into two equal halves is known as the (interior) bisector of the an angle.

A bisector is a tool that divides an angle equally into two equal halves. Divide the number of degrees in the angle by two to determine the angle bisector.

If the angle bisector of ADC is the ray CE

then,

Angle ACD = ACE + ECD

ACE = ECD

So,

ACD = 2(ACE)

ACE = 1/2 (ACD)

This implies that ∠ACE = ∠DCB.

Solving the problem as per a linear equation, the value of b is found to be 1/10.

A linear equation is a form of algebraic equation in which the highest value of a variable is always equal to 1. Such an equation forms a straight line when carved on a graph.

As provided, the given equation is,

1/b = 4/2b - 10

or, 1/b = 2/b - 10 (as 4/2 = 2 )

or, 1/b - 2/b = - 10

or, 1/b ( 1 - 2) = - 10

or, - 1/b = - 10, ( we are using cross multiplication )

Answer:

Step-by-step explanation:

Answer: I believe A is 52 degrees.

Solution:  Find angle c (D + C adds up to 180 degrees cuz its a line)

So do 180-116=64 degrees

Assuming this is an isosceles triangle because the sides on d and c look equal, we know that those 2 angles add up to 128 degrees(64 + 64).

Therefore, since the shape is a triangle(adds up to 180 degrees) you just do 180 minus 128 to get angle A which is 52 degrees.
