Therefore, greatest common factor is (5x + 7)

Answer:

if your dividing then 3 but if you want 21 sevenths as a mixed number then it would be 3.

Step-by-step explanation:

to find the quotient, you need to find out what multiplied by 7 gives you 21. (thats easy 3) so there is your answer. to find the mixed version of 21 sevenths you need to divide 21 by 7 ( literally what  i just showed...) and you get 3.

a = –2 and b = 3

Solution:

Given equations are

3a – b = –9 – – – – (1)

–3a – 2b = 0  – – – – (2)

To solve these equations by elimination method.

Elimination method means eliminating one variable to find the other variable.

Add equation (1) with equation (2), we get

3a – b + (–3a – 2b) = –9 + 0

⇒ 3a – b – 3a – 2b = –9

Combine like terms together.

⇒ 3a – 3a – b – 2b = –9

⇒ 0 – 3b = –9

⇒ – 3b = –9

Divide by (–3) on both sides, we get

⇒ b = 3

Substitute b = 3 in equation (1), we get

(1) ⇒ 3a – b = –9

⇒ 3a – 3 = –9

Add 3 on both sides of the equation,

⇒ 3a = –6

Divide 3 on both sides of the equation

⇒ a = –2

Hence, a = –2 and b = 3.

[tex]\large\boxed{y=\dfrac{1}{4}x^2-x-4}[/tex]

Step-by-step explanation:

The equation of a parabola in vertex form:

[tex]y=a(x-h)^2+k[/tex]

(h, k) - vertex

The focus is

[tex]\left(h,\ k+\dfrac{1}{4a}\right)[/tex]

We have the vertex (2, -5) and the focus (2, -4).

Calculate the value of a using [tex]k+\dfrac{1}{4a}[/tex]

k = -5

[tex]-5+\dfrac{1}{4a}=-4[/tex]        add 5 to both sides

[tex]\dfrac{1}{4a}=1[/tex]           multiply both sides by 4

[tex]4\!\!\!\!\diagup^1\cdot\dfrac{1}{4\!\!\!\!\diagup_1a}=4[/tex]

[tex]\dfrac{1}{a}=4\to a=\dfrac{1}{4}[/tex]

Substitute

[tex]a=\dfrac{1}{4},\ h=2,\ k=-5[/tex]

to the vertex form of an equation of a parabola:

[tex]y=\dfrac{1}{4}(x-2)^2-5[/tex]

The standard form:

[tex]y=ax^2+bx+c[/tex]

Convert using

[tex](a-b)^2=a^2-2ab+b^2[/tex]

[tex]y=\dfrac{1}{4}(x^2-2(x)(2)+2^2)-5\\\\y=\dfrac{1}{4}(x^2-4x+4)-5[/tex]

use the distributive property: a(b+c)=ab+ac

[tex]y=\left(\dfrac{1}{4}\right)(x^2)+\left(\dfrac{1}{4}\right)(-4x)+\left(\dfrac{1}{4}\right)(4)-5\\\\y=\dfrac{1}{4}x^2-x+1-5\\\\y=\dfrac{1}{4}x^2-x-4[/tex]

ANSWER: Exact Form: [tex]\sqrt{10}[/tex]

Decimal Form:  3.16227766

STEP-BY-STEP EXPLANATION:

(1, 2) and (4,3)

Use the distance formula to determine the distance between the two points.

Distance = \sqrt{(X2-X1)^{2  }+ (Y2-Y1)^{2} }

Substitute the actual values of the points into the distance formula.

\sqrt{(4-1)^{2  }+ (3-2)^{2} }

The result can be shown in multiple forms.

Exact Form: [tex]\sqrt{10}[/tex]

Decimal Form:  3.16227766

The distance between the given points is approximately 3.16 units.

To find the distance between the points (1, 2) and (4, 3), we use the distance formula derived from the Pythagorean Theorem, which calculates the distance between two points in a coordinate plane. The distance formula is:
d = √((x₂ - x₁)² + (y₂ - y₁)²).
Using this formula, we plug in the coordinates of the two points:

Let (x₁, y₁) = (1, 2)

Let (x₂, y₂) = (4, 3)

Substituting these values into the formula gives us:

d = √((4 - 1)² + (3 - 2)²)
d = √(32 + 12)
d = √(9 + 1)
d = √10
d ≈ 3.16

Therefore, the distance between the two points is approximately 3.16 units.

Answer:

–43p + (–25)  is  EQUIVALENT to  –43p – 25.

Step-by-step explanation:

The options are MISSING.

The needed options are:

1. 25 – 43p

2. 25 – 43p

3. –25p –43

4. –43p + (–25)

Now, here the given expression is:  –43p – 25

Taking each option and simplifying it , we get:

1. 25 – 43p

Here, the second term is NEGATIVE, but the first term (25) is POSITIVE.

⇒  25 – 43p  ≠ –43p – 25

Hence, 25 – 43p is  NOT EQUIVALENT.

2. 25 – 43p

Here, the second term is NEGATIVE, but the first term (25) is POSITIVE.

⇒  25 – 43p  ≠ –43p – 25

Hence, 25 – 43p is  NOT EQUIVALENT.

3. –25p –43

Here, the variable p is multiplied with (-25) and NOT (-43).

⇒   –25p –43 ≠ –43p – 25

Hence,  –25p –43 is  NOT EQUIVALENT.

4. –43p + (–25)

Here, both the given terms (43) and (25) are NEGATIVE.

Also, the varibale p is multiplied with (-43)

⇒  –43p + (–25) = –43p – 25

Hence, –43p + (–25)  is  EQUIVALENT.

Answer:

A dodecagon.

Answer:

The equation of a line through (5 -3) that is parallel to y = 1/2 x+3 is

y = - 2 x  + 7

Step-by-step explanation:

Let us assume the slope of the line whose equation we need to find is m 1.

The line parallel to the needed line  is:   y=1/2x+3

Comparing it with the general form: y = m x + C

we get m 2 = 1/2

Now, as Line 1 is Perpendicular to Line 2.

⇒ m 1 x m 2  = -1

⇒ m 1 x ( 1/2)  = -1

⇒ m 1  = - 2

Also, the point son the line 1 is given as: (x,y)  = (5,-3)

Put the value of point and Slope in y = m x + C to find the value of Y- INTERCEPT.

we get: -3 = (-2) (5) +  C

or, C = -3 + 10 = 7

⇒ C = 7

The general line equation is given as:  y = m x + C

Substituting  the values of C and m, we get:

y = - 2 x  + 7

Hence, the equation of a line through 5 -3 that is parallel to y = 1/2 x+3 is

y = - 2 x  + 7

Answer:

2z +3

Step-by-step explanation:

This question simply involves understanding what like terms are, and how to combine them.

Here, 5z and -3z are like terms, so we combine them by going 5z-3z = 2z

(i.e. we minus the coefficients, but the z stays unchanged).

Next, the number term of 3 in the middle cannot be combined with any other term, so it just stays in the expression.

Answer:

3x + 1 <-5 is x<−2

5x-1> 29 is x>6

Step-by-step explanation:

Isolate the variable by dividing each side by factors that don't contain the variable.

Inequality Form:

x<−2

Isolate the variable by dividing each side by factors that don't contain the variable.

Inequality Form:

x>6

Final answer:

To solve the compound inequality 3x + 1 < -5 OR 5x - 1 > 29, solve each inequality separately. The solution is all real numbers that are either less than -2 or greater than 6.

Explanation:

To solve the compound inequality 3x + 1 < -5 OR 5x - 1 > 29, we need to solve each inequality separately and then find the union of the two solutions, since the word 'OR' indicates that a solution to either inequality will satisfy the compound inequality.

Solving the first inequality:

3x + 1 < -5

Solving the second inequality:

5x - 1 > 29

The solution to the compound inequality is the set of all real numbers that are either less than -2 or greater than 6.

Answer:

  x less 16.5

Step-by-step explanation:

"x -16.5" means 16.5 is subtracted from x. The resulting value is 16.5 less than x. The wording "x less 16.5" basically means "x minus 16.5" and/or "x reduced by 16.5".

__

Subtraction is not commutative, so "16.5 decreased (or reduced) by x", meaning "16.5 -x" or "16.5 minus x", is not the same thing.

The statement is true. The rational roots of a polynomial can be written in the form p/q. The rational root theorem is used to determine these potential roots.

The statement in the question is true.

The rational roots of a polynomial function can indeed be written in the form p/q, where p is a factor of the leading coefficient and q is a factor of the constant term. This is known as the Rational Root Theorem.

For example, if we have the polynomial function f(x) = 3x^3 - 7x^2 + 4x - 2, the leading coefficient is 3 and the constant term is -2. The potential rational roots would be of the form p/q, where p is a factor of -2 and q is a factor of 3. The factors of -2 are -1, 1, -2, and 2, while the factors of 3 are -1 and 3. Therefore, the potential rational roots would be:

Answer:

EF = 6m.

Step-by-step explanation:

Given that:

1) All the edges of the pyramid in the model have length 12m.

So, AB = 12m

2) E is the middle of AT, F is the middle of BT

So, EF is a line segment connecting the midpoints of ΔATB

So, by applying The Triangle Mid-segment Theorem

EF // AB and EF = 0.5 AB

So, EF = 0.5 AB = 0.5 * 12 = 6m

====================================

The Triangle Mid-segment Theorem:

The line segment connecting the midpoints of any two sides of a triangle has the following properties:

1) The line segment will be parallel to the third side.

2) The length of the line segment will be a half of the length of the third side.
