Answer:

Katie saved $35 last month.

Step-by-step explanation:

we are given that, Katie wants to buy a bicycle that costs $129.

This is $24 more than 3 times what katie saved last month.

Let Katie, saved $x last month.

So we can write

3x+24=129\\\text{Add-24 on both the sides}\\3x+24-24=129-24\\3x=105\\\text{Divide both the sides by 3, we get}\\x=35\\\text{So she saved last month }$35.

Which equations represent the line that is parallel to 3x − 4y = 7 and passes through the point (−4, −2)? Select two options. y
xz_007 [3.2K]

Answer:

<em>The equation of the parallel  line to the given equation is </em>

<em>3 x-4 y = -4    and </em>

<em>The equation of the parallel  line to the given equation is </em>

y = 1 + \frac{3 x}{4}

<em></em>

Step-by-step explanation:

<u><em>Explanation</em></u>:-

Given equation of the line 3 x -4 y = 7 and given point ( -4 , -2 )

<em>The equation of the parallel line to the given equation is </em>

<em>3 x - 4 y = k </em>

it is passes through the point ( -4 , -2)

3 (-4) - 4 ( -2) = k

-12 +8 = k

k = -4

<em>The equation of the parallel  line to the given equation is </em>

<em>3 x- 4 y = -4 </em>

<em>Dividing '4' on both sides , we get</em>

<em></em>\frac{3 x-4 y}{-4} = 1<em></em>

<em></em>\frac{-3 x}{4} +y =1<em></em>

<em></em>y = 1 + \frac{3 x}{4}<em></em>

<u><em>Conclusion</em></u>:-

∴ <em>The equation of the parallel  line to the given equation is </em>

<em>3 x- 4 y = -4 </em>

<em>and </em>

<em>The equation of the parallel  line to the given equation is </em>

y = 1 + \frac{3 x}{4}

<em>     </em>

The function y = x2 is transformed to y = (x + 4)2. Which statement is true about the transformed function? It is an even functi
xxMikexx [17]
Even function: f(-x) = f(x). If you replace x by -x you should find the same function.
Odd function: f(-x) = -f(x). If you replace x by -x you  find the same function with opposite sign;
Is f(-x) = f(x)?
f(x) = (x+4)² =  x² + 8x +16
f(-x) = (-x+4)² = x² - 8x + 16, then it's not an even function

Is f(-x) = -f(x)?
f(-x) = (-x+4)² = x² + 8x + 16 , then it's not an odd function
It is neither an even nor an odd function

Write the perimeter of the triangle in<br> simplest form.
Genrish500 [490]

Answer:

6x +3

Step-by-step explanation:

Perimeter of a triangle is the sum of all the length of its sides. Since a triangle as 3 sides, add the 3 lengths together.

Perimeter of triangle= 2x -6 +x +8 +3x +1

<em>Bringing</em><em> </em><em>all</em><em> </em><em>the</em><em> </em><em>x</em><em> </em><em>terms</em><em> </em><em>together</em><em> </em><em>and</em><em> </em><em>constants</em><em> </em><em>together</em><em>:</em>

Perimeter of triangle= 2x +x +3x -6 +8 +1

<em>Simplify:</em>

Perimeter of triangle= 6x +3
