Solve by substitution. Please show work!!! x+4y=-3 x+7y=-12

Describe how the graph of y = x2 can be transformed to the graph of the given equation.

Vikki [24]

1.Describe how the graph of y = x2 can be transformed to the graph of the given equation.

y = (x+17)2

Shift the graph of y = x2 left 17 units.

2.Describe how the graph of y= x2 can be transformed to the graph of the given equation.

y = (x-4)2-8

Shift the graph of y = x2 right 4 units and then down 8 units.

.Describe how to transform the graph of f into the graph of g.

f(x) = x2 and g(x) = -(-x)2

Reflect the graph of f across the y-axis and then reflect across the x-axis.

Question 4 (Multiple Choice Worth 2 points)

Describe how the graph of y= x2 can be transformed to the graph of the given equation.

y = x2 + 8

Shift the graph of y = x2 up 8 units.

Question 5 (Essay Worth 2 points)

Describe the transformation of the graph of f into the graph of g as either a horizontal or vertical stretch.
f as a function of x is equal to the square root of x and g as a function of x is equal to 8 times the square root of x

f(x) = √x, g(x) = 8√x

vertical stretch factor 8

What additional Information needed to prove the triangles are congruent by the SAS Postulate? Angle XWY cong angle ZWY; angle YX

marusya05 [52]

Answer:

WX = WZ

Step-by-step explanation:

Given

See attachment for triangles

Required

Additional information to prove the congruence of the triangles

Congruence by SAS means 1 angle and 2 sides of each triangles are equal.

The mark on angle W means that <XWY = <ZWY--- This represent the A in SAS

Both triangles share line WY.

So, WY = WY

Lastly, to complete the proof, lines WX must equal line WZ

Pls help me with this question

Sedbober [7]

7/12, 3/4, 4/7, 5/8, 4/7

Answer:

Order from Least to Greatest

4/7 = 4/7 < 7/12 < 5/8 < 3/4

Showing Work

Rewriting as fractions if necessary:

7/12, 3/4, 4/7, 5/8, 4/7

The least common denominator (LCD) is: 168.

Rewriting as equivalent fractions with the LCD:

98/168, 126/168, 96/168, 105/168, 96/168

Ordering these fractions by the numerator in order from least to greatest:

96/168 = 96/168 < 98/168 < 105/168 < 126/168

Therefore, your input in order from least to greatest is:

Answer =======> 4/7 = 4/7 < 7/12 < 5/8 < 3/4

B): 1.35, 5/4, 1.349, 6/5, 7/6

Number of inputs ====> 5

Answer => Ascending Order: Least to Greatest =====> 7/6, 6/5, 5/4, 1.349, 1.35

C): 0.819, 0.8199, 81/100, 815/1000

Number of Inputs ======> 4

Answer ==> Ascending order (Least to Greatest ====> 81/100, 815/1000, 0.819, 0.8199

D): 3 4/7, 245/70, 3.572, 90/29

Number of Inputs: 4

Answer ==> Ascending Order(Least to Greatest) ==> 90/29, 245/70, 3.572, 3 4/7

Hope that helps!!!! : )

How do you find the arctan 4/3 ? (Without a calculator)

Soloha48 [4]

If arctan 4/3 = the tangent of that angle will be 4/3 , opposite 4 over adjacent 3

Now, you only have to take the sin of that angle it's opposite 4 over hypotenuse 5.

You will get that the answer is 4/5

hope this helps
