evaluate the expression if x =6 and y =7. 3x+2y

Answers

ANSWER: 18 + 14

EXPLANATION: It says x =6 and y=7
And if number are rite next to each other with no symbol you always multiply so it would be 3 6 + 2 7 so 3x6=18 and 2x7=14 so it would be 18+14

The value of the expression 3x + 2y when x =6 and y =7 is 32.

What is an expression?

An expression is a combination of some mathematical symbol such that an arithmetic operator and variable such that all are constrained and create an equation.

In other meaning, expression is very useful to determine the end or root value of constraint.

As per the given expression, 3x + 2y

Put x = 6 and y = 7 as,

3(6) + 2(7) = 18 + 14 = 32

Hence "The value of the expression 3x + 2y when x =6 and y =7 is 32".

Which statement is true about a translation? 1. A translation takes a line to a parallel line or itself. 2. A translation takes a line to a perpendicular line. 3. A translation requires a center of translation. 4.A translation requires a line of translation.

Answers

Answer: 1. A translation takes a line to a parallel line or itself.

Step-by-step explanation:

I took the quiz myself.

When a line is translated, it means the line is moved from one position to another. The true statement is:

(1). A translation takes a line to a parallel line or itself.

In transformation, translation does not change the orientation of a line. This means that:

The position of the lines will change, when translatedThe orientation of the lines will remain unchangedIt does not require a center or scale of translation

Point (2) above means that;

Parallel lines will remain parallelPerpendicular lines will remain perpendicular

Using the above analysis, we can conclude that: option (1) is true

If f(x) is x² the answer for f(g(x))= (x-6)²

If f(x) is 2x the answer for f(g(x))=2x-12

Answers

Answer:

Step-by-step explanation:

In order to find an expression equivalent to [tex]4(x+2y)[/tex], we want to simplify the equation down.

To do this, we can see that we can apply the distributive property on this equation. Basically, we multiply every term in the parentheses by 4.

[tex]4 \cdot x = 4x\\\\4 \cdot 2y = 8y\\\\4x+8y[/tex]

Step-by-step explanation:

This equation here is shown in the form of [tex]y = x-4[/tex]. However, we are solving for x when we know y. I find it easier to convert the equation so we have [tex]x = ...[/tex]. To do this we can add 4 to both sides.

[tex]y + 4 = x, x = y+4[/tex].

Now that we know our equation ([tex]x = y+4[/tex]), we can substitute the values of y inside to find x.

[tex]x = 6+4\\\\x = 10[/tex]

[tex]x = 0+4\\\\x = 4[/tex]

[tex]x = 4+4\\\\x = 8[/tex]

If AB = 8 and BC = 24, then AC =

If AB = 17 and AC = 68, then BC =

Answers

Answer:

(i) The length of AC is 32 units, (ii) The length of BC is 51 units.

Step-by-step explanation:

(i) Let suppose that AB and BC are collinear to each other, that is, that both segments are contained in the same line. Algebraically, it can be translated into this identity:

[tex]AC = AB + BC[/tex]

If we know that [tex]AB = 8[/tex] and [tex]BC = 24[/tex], then:

[tex]AC = 8 + 24[/tex]

[tex]AC = 32[/tex]

The length of AC is 32 units.

(ii) Let suppose that AB and AC are collinear to each other, that is, that both segments are contained in the same line. Algebraically, it can be translated into this identity:

[tex]AC = AB + BC[/tex]

[tex]BC = AC - AB[/tex]

If we know that [tex]AC = 68[/tex] and [tex]AB = 17[/tex], then:

[tex]BC = 68-17[/tex]

[tex]BC = 51[/tex]

The length of BC is 51 units.
