Alina and Skyla are both solving the equation 2x = 128.
Alina knows the solution to the equation because she knows a power of 2 that equals 128.
Skyla does not know a power of 2 that equals 128, so she graphs two equations, y = 2x and y = 128.
Use the drop-down menus to complete the explanation about how Skyla can use her graph to solve the equation 2x = 128.
Answer:
Skyla looks for the x-value at which the graph of the function [tex]2^x[/tex] intersects the horizontal line defined by the constant function: [tex]f(x)=128[/tex]
Step-by-step explanation:
Look for an answer that involves something like:
By looking for the point where both functions intersect, Skyla can find for which x value the following equation is verified: [tex]2^x=128[/tex]
She must read at which x-value the intersection occurs, and that is the answer.
Answer: Intersect at (7,128) and x=7

Answer:
Using the information given, we can use the point-slope form:
y - y1 = m(x - x1)
y - 7 = -1(x + 3)
y - 7 = -x - 3
+7 +7
y = -x + 4, this is slope-intercept form

Problema:1,745 kilómetros de distancia entre Mérida, Yucatán y Ciudad Victoria, Tamaulipas.1: 100 000 Escala en el mapa.¿Cuántos centímetros representan estos kilómetros en el mapa?
Answer:
1745 centimeters.
Step-by-step explanation:
The first thing is to pass the kilometers to centimeters, we know 1 km equals 100000 cm, therefore:
1745 km * 100000 cm / 1 = 174500000 cm
Now, when applying the scale, we have that it is 1: 100000, so we apply the scale:
174500000 * 1/100000 = 1745
That is to say that on the map those 1745 kilometers represent 1745 centimeters.

What is the slope of the line that passes through the points (-8, -3) and
(-12, -3)? Write your answer in simplest form.
Answer:
slope = 0
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 8, - 3) and (x₂, y₂ ) = (- 12, - 3)
m = [tex]\frac{-3+3}{-12+8}[/tex] = [tex]\frac{0}{-4}[/tex] = 0
Slope is rise per run. Rise is difference of y ordinates and run is difference of corresponding x abscissa.
The slope of the line that passes through the given points is 0
Given that:The two specified points are: (-8,-3), and (-12, -3)To find:
Slope of the line that passes through given points.
In graphing, we use Cartesian plane and assume y axis to be perpendicular and mostly we take height or depth related stuffs on y axis, that's why y ordinates will be considered to calculate the rise and x axis is like flat ground, thus x abscissa will be used to calculate the run.
Let the points' coordinates are denoted by symbols as:
[tex](x_1, y_1) = (-8,-3)\\ (x_2, y_2) = (-12, -3)\\ [/tex]
[tex]slope = \dfrac{rise}{run} = \dfrac{y_2 - y_1}{x_2 - x_1} = \dfrac{(-3) - (-3)}{(-12)-(-8)} = \dfrac{0}{-4} = 0[/tex]
Slope is zero means you run whatever, the rise is 0, which means the line is not going to rise and stay flat (horizontal).

The price of the box of 10 markers is $7. The price of the box of 24 markers is $14. All prices without tax, and the price of the boxes is the same. WILL MARK BARINLEIST OR WHATEVER YOU CALL IT I WILL
a) Write an equation which tell the price Y for the number of markers X
The linear equation where y is the price of the number of markers x is as follows:
y = 1 / 2 x + 2Let
the price of each marker = y
Therefore,
The price of a box with 10 markers = $7
The price of a box with 24 markers = $14
(10, 7)(24, 14)
Using linear equation
Slope intercept formy = mx + bwhere
m = slope
b = y-intercept
Therefore,
m = 14 - 7 / 24 - 10
m = 7 / 14
m = 1 / 2
Therefore, let's find b
7 = 1 / 2(10) + b
7 - 5 = b
b = 2
Therefore, the linear equation where y is the price of the number of markers x is as follows:

Answer:
y = 1/2x+2
Step-by-step explanation:
We have two points ( 10,7) and (24,14)
We need to determine the slope using the slope formula
m = ( y2-y1)/(x2-x1)
= ( 14-7)/(24-10)
= 7/14
= 1/2
The slope is 1/2
The slope formula is y=mx+b where m is the slope and b is the y intecept
y = 1/2x+b
Using one of the points
7 = 1/2 (10)+b
7 = 5+b
7 -5 =b
2=b
y = 1/2x+2

Answer:
x = 19° ; Write 19° in the box ( don't forgot ° or answer will be incorrect )
Step-by-step explanation:
If XW ║YZ, we can tell that YW is a transversal, as YW ∩ XW, YX;
By alternate interior angles, ∠ ZYW ≅ ∠ YWX, so that ⇒
m∠ ZYW = m∠ YWX,
m∠ YWX = 2x, ⇒ given m∠ ZYW = 2x
By ∑ of angles in triangle Theorem;
m∠ YXW + m∠ XYM + m∠ YWZ = 180° ⇒ through substitution,
( 3x - 5 ) + 90 + ( 2x ) = 180 ⇒ now apply algebra,
3x - 5 + 90 + 2x = 180 ⇒ combine like terms,
3x + 2x - 5 + 90 = 180 ⇒ add,
5x + 85 = 180 ⇒ subtract 85 from either side of equation,
5x = 95, divide 5 on either side,
x = 19°
Solution; x = 19°

D.
The surface area of the pyramid is multiplied by 1,000.
E.
The effect on the surface area cannot be determined.
Answer:
C
Step-by-step explanation:
Since the question is asking for surface area and the dimensions are multiplied by 10, the surface area is multiplied by 10^2, or 100. (For area it would be 10^3, or 1000)
the perimeter of a rectangle is84cm and its length is 6cm longer than its breadth.find the lenth and breadth of the rectangle
So,the length of rectangle is 24 cm

liz is installing a tile backsplash. if each tile is an equilateral triangle with sides that measures 6 cm in length how many tiles does she need to cover an area of 1800 cm²
Answer:
116 tiles
Step-by-step explanation:
You want to know the number of 6 cm equilateral triangle tiles required to cover 1800 cm².
AreaThe area of an equilateral triangle of side s is given by the formula ...
A = (√3/4)s²
The area of a 6 cm equilateral triangle tile is ...
A = (√3/4)(6 cm²) = 9√3 cm² ≈ 15.588 cm²
TilesThe number of tiles required is the total area divided by the area per tile:
1800 cm² / (15.588 cm²/tile) ≈ 115.47 tiles
In order to cover 1800 cm², Liz will need 116 triangular tiles.
Answer:
100 tiles
Step-by-step explanation:
Each tile is an equilateral triangle with sides 6 cm in length, so the area of each tile can be found using the formula for the area of a triangle:
[tex]\sf:\implies{A = (b \times h) / 2}[/tex]
where b is the base and h is the height.
Since each side of the triangle is 6 cm, the base and height of the triangle are both 6 cm, so:
[tex]\sf:\implies{A = (b \times h) / 2}[/tex]
[tex]\sf:\implies{A = (6 \times 6) / 2}[/tex]
[tex]\sf:\implies{A =18}[/tex]
So each tile has an area of 18 cm².
To find the number of tiles needed to cover an area of 1800 cm², divide the total area by the area of each tile:
[tex]\sf:\implies{A = 1800 / 18}[/tex]
[tex]\sf:\implies{A = 100}[/tex]
Therefore, Liz needs 100 tiles to cover an area of 1800 cm².

Answer:
D
Step-by-step explanation:
When you graph, you can see that the Line crosses the x at (-3,0) and then passes through the y at (0, 12)
Answer:
D
Step-by-step explanation:
To find the intercepts, set the variable you are not trying to find to 0. Also, in case you don't know, f(x) and y are the same thing here. So on this question, it would be:
X-Intercept:
0=4x+12
-12=4x
-3=x
so x intercept is (-3,0)
Y-Intercept:
y=4(0)+12
y=12
so y intercept is (0,12)
