Pythagorean Theorem: a² + b² = c²Step-by-step explanation:
Step 1: Define
We are given a right triangle. We can use Pythagorean Theorem.
a = 19
b = x
c = 21
Step 2: Find x
Substitute: 19² + x² = 21²Isolate x term: x² = 21² - 19²Evaluate: x² = 441 - 361Subtract: x² = 80Isolate x: x = √80Simplify: x = 4√5And we have our final answer!

Point P′(−3, 2) is the image of point
P(3, 8) under a translation. What
is the image of (0, −6) under the
same translation?
Answers
Answer:
The image of (0, -6) after the same transformation is (-6, -12)
Step-by-step explanation:
After the required translation, the given image of the given point P(3, 8) is P'(-3, 2)
Therefore, the translation of preimage P(3, 8) to the image P'(-3, 2) is given by the difference between the coordinates as follows;
The translation from P(3, 8) to P'(-3, 2) = T(-3 - 3, 2 - 8) = T(-6, -6)
Therefore after the same translation, the preimage of (0, -6) will have an image given as follows;
Coordinate of preimage (0, -6) → T(-6, -6) (0, -6) = (0+ -6, -6 + -6) → Coordinate of image (-6, -12)
The image of (0, -6) after the same transformation = (-6, -12).

Answer:
h ( -6 ) = -13228
Step-by-step explanation:
h ( x ) = -10x^(4) - 9x^(2) - 8x + 8
evaluate when, x = -6
Substitute in -6, for x,
-10(-6)^(4) - 9(-6)^(2) - 8(-6) + 8
= -10(1296) -9(36) -8(-6) + 8
= -12960 - 324 + 48 + 8
= -13284 + 56
= - 13228

Write an equation of the line in standard form.
The line has the same slope as 3x-y=5 and the same y-intercept as the graph of 2y- 15x = 8.
The equation in standard form is
Answers
Answer:
Ok to make this easier for us we should switch these equations into y=mx+b so that it's easier for us to identify the slope and y-intercept:
to switch into y=mx+b form do this:
3x-y=5
-y=5-3x
y=-5+3x
y=3x+(-5)
2y-15x=8
2y=8+15x
y=4+7 1/2x
y=7 1/2x+4
THe slope of any line in y=mx+b form is m. Therefore in this equation:
y=3x+(-5) 3 is the slope
The y intercept of any line is the +b:
y=7 1/2x+4 -therefore 4 in this equation is our y intercept.
Now we can construct our equation in y=mx+b then into standard form (Ax+By=C)
since 3 is our slope and 4 is our y intercept the equatuon is :
y=3x+4
NOw all we need to do is move this into standard form:
y=3x+4
-3x+y=4
-3x+y=4 is your final answer

Mario runs a yard company. He charges $20 to show up for the job and $4 for each 10 square Yards. His competition, Linda's Lawn Care, charges $10 for showing up and $6 for each square 10 yards. After how many 10 square yards are, they charging the same? And how much is charged at that moment?
Answers
Answer:
5 square 10 yards
$40
Step-by-step explanation:
Mario:
20 + 4x
Her competitor:
10 + 6x
Where,
x = number of 10 square yards
Equate the expressions
20 + 4x = 10 + 6x
Collect like terms
20 - 10 = 6x - 4x
10 =2x
Divide both sides by 2
x = 10 / 2
= 5
x = 5 square 10 yards.
Charge at that moment
Using any of the cost equation
10 + 6x
= 10 + 6(5)
= 10 + 30
= 40
$40
Or
20 + 4x
= 20 + 4(5)
= 20 + 20
= $40

Brenda has two pieces of string, one 28 feet long and the other 42 feet long. For an art project, she wants to cut them up to produce many pieces of string that are all of the same length, with no string left over. What is the greatest length, in feet, that she can make them?
Answers
Answer:
7 feet
Step-by-step explanation:
Length of one piece of string = 28 feet.
Length of the second string = 42 feet.
Since the number of required pieces was not given but many are required, the greatest length can be determined by;
If the maximum length is 7 feet, then:
the number of pieces from 28 feet long string = [tex]\frac{28}{7}[/tex]
= 4
Also,
the number of pieces from the 42 feet lone string = [tex]\frac{42}{7}[/tex]
= 6
Total number of 7 feet strings that she can make = 4 + 6
= 10
Since many pieces are required, the greatest length she can make is 7 feet. If she increase the length to 14 feet, the number of pieces would be 5 which limit the required number.

What is the slope of the line through the points (0,-3) and (2,1)?
Answers
Answer:
alright so you got 2 points! now this is the slope formula! y2-y1/x2-x1
okay let's label your points! (x1 0,y1 -3) (x2 2,y2 1)
let's follow the formula this makes it so we can solve! 1--3/2-0
I understand you may get a decimal but don't use 2.5 use a fraction because teachers seem to like fractions and general decimals can be hard to use (experience lol) 2.5 is 5/2 so this means your slope is 5/2
this formula works every single time and if you memorize it you can do any other problems with 2 points! please memorize y2-y1/x2-x1
