translate the triange 2 units left and 1 unit up. then reflect the image in the x axis . graph the FINAL triange .

Answers

Can’t graph the image but it’s asking you to move the image 2 units to the left, so move all the points of the triangle 2 units left, then do the same thing with all the pints except bring those points up 1. Now reflect the triangle over the x axis. You can do this by grabbing some patty paper or paper and just drawing the triangle, then just turn it over the x axis and it will give you your reflected triangle.

Will anyone help me on this? what do i shade green and red?? please let me know! everyone who's answered on this app has given weird, random responses. thanks in advance! ​

Answers

Step-by-step explanation:

Hοmοzygous means both letters are uppercase, or both are lowercase.

Heterozygous means one is uppercase and the other is lower case.

Dominant is represented by uppercase.  Recessive is represented by lowercase.

"Hοmοzygous dominant" is NN.

"Heterozygous" is Nn.

"Hοmοzygous recessive" is nn.

Shade NN red, and shade Nn green.  Leave nn unshaded.

Please answer these questions.It is only two questions and they are super small.I have put the picture of the question down below.

Answers

Answer:

9. y= ¼x -5

10. y= 2x +18

Step-by-step explanation:

Slope-intercept form:

y= mx +c, where m is the slope (also known as gradient) and c is the y-intercept.

9. The given equation is already written in the slope-intercept form. The coefficient of x is ¼, thus the gradient of the given line is ¼.

Parallel lines have the same gradient and hence, gradient of line is also ¼.

Substitute m= ¼ into the equation:

y= ¼x +c

To find the value of c, substitute a pair of coordinates.

When x= 8, y= -3,

-3= ¼(8) +c

-3= 2 +c

c= -3 -2

c= -5

Thus, the equation of the line is y= ¼x -5.

10. Gradient of given line= 2

Parallel lines have the same gradient.

Thus, gradient of line= 2

Substitute m=2 into the equation:

y= 2x +c

When x= -4, y= 10,

10= 2(-4) +c

10= -8 +c

c= 10 +8 (+8 on both sides)

c= 18

Therefore, the equation of the line is y= 2x +18.

Answers

Answer:

Speed of priya = 2.2 m/s

Mai was faster.

Step-by-step explanation:

Given:

Mai cover 15 meter in 6 second

Priya cover 22 meter in 10 second

Find:

Who was faster

Speed of priya

Computation:

Speed = Distance / time

Speed of mai = 15 / 6

Speed of mai = 2.5 m/s

Speed of priya = 22 / 10

Speed of priya = 2.2 m/s

Mai was faster.

Nora jogs 414 miles on Monday. She jogs 112 fewer miles on Tuesday. Write and evaluate an addition expression to find how many miles Nora jogs on Tuesday.

Answers

Answer:

Let's define the variables:

M = # of miles that Nora jogs on Monday

T = # of miles that Nora Jogs on Tuesday

We know that:

"Nora jogs 414 miles on Monday"

Then we have:

M = 414 mi

"She jogs 112 fewer miles on Tuesday"

This can be written as:

T = M - 112 mi

This is the equation that we need to solve.

Here we can simply replace the value of M by 414mi and get:

T = 414 mi - 112 mi = 302 mi.

Nora jogs 302 miles on Tuesday.

Step-by-step explanation:

Given: 3x - 14 = 43
Prove: x = 19

Answers

Step-by-step explanation:

Because you're trying to prove the value of X, you work backwards. here's what you do

When working backwards, PEMDAS becomes SADMEP

First, add 14 to 43 (57).

Then, divide 57 by 3 to get 19.

x = 19!

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

PEMDAS is the order of operation, and equals:

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction

First, add 14 to both sides of the equation:

3x - 14 (+14) = 43 (+14)

3x = 43 + 14

3x = 57

Next, divide 3 from both sides of the equation:

(3x)/3 = (57)/3

x = 57/3

x = 19

~

Proof: Plug in 19 for x in the equation for x:

3(19) - 14 = 43

First, multiply:

(3 * 19) - 14 = 43

(57) - 14 = 43

Next, subtract:

57 - 14 = 43

43 = 43 (True).

hheleoghelp what is the volume of the following rectangular prism?

Answers

Answer:

28 units^3

Step-by-step explanation:

The formula for finding the volume of a rectangular prism is V = lwh or V = bh

l = length

w = width

h = height

b = base

V = volume

Because we are given the base and height we will use the second formula, V =bh.

V = (8/3)(21/2)

Because we are multiplying fractions, you can just multiply across:

V = 168/6

V = 28 units^3

A hill on a hiking trail goes up to 69 feet over a distance of 138feet. Find the grade of the hill

Answers

Answer: The grade of the hill = 50%

Step-by-step explanation:

The grade is the slope( expressed as a percent). To evaluate the slope we divide the rise by the run.

Given: A hill on a hiking trail goes up to 69 feet over a distance of 138 feet.

So, rise= 69 feet   , run = 138 feet.

The grade of the hill = [tex]\dfrac{rise}{run}\times100[/tex]

[tex]=\dfrac{69}{138}\times100=50\%[/tex]

Hence, the grade of the hill = 50%

Step-by-step explanation:

Step 1. add 11 to both sides

3x + 4 = 8x - 11

    +11         +11

3x + 15 = 8x

Step 2. subtract 3x from both sides

- 3x        -3x

15 = 5x

Step 3. divide by 5 to isolate x

15 = 5x
