Answer:
3. (-1 , 3) , 4
4. (0 , -7), 8
Step-by-step explanation:
circle: (x-h)² + (y-k)² = r²
3. x²+2x+y²-6y-6 =0
(x²+2x+1) + (y²-6y+9) -16 =0
(x+1)² + (y-3)² = 4²
center(-1 , 3) radius: 4
4. x²+y²+14y-15=0
(x+0)² + (y²+14y+7²) - 64 = 0
(x+0)² + (y+7)² = 8²
center: (0 , -7) radius: 8
Answer:
3. Center = (-1,3) Radius = 4
4. Center = (0,-7) Radius = 8
use completion of squares to find the solution, if you do not understand what this means, there is a great video on utube by the channel Prep Expert that explains finding the center of a circle based on an equation.

Write the sum, and then write an equivalent expression by collecting like terms and removing parentheses whenever possible.
d. The opposite of - 10t and t - 10t
Answer:
The sum is [tex]t[/tex].
Step-by-step explanation:
Consider the provided information.
The given expression are - 10t and t - 10t
We need to find the sum of the opposite of -10 t and t - 10t.
The opposite of -10 t is 10 t.
[tex]10t+(t-10t)[/tex]
Remove the parenthesis.
[tex]10t+t-10t[/tex]
Simplify the number
[tex]10t-10t+t[/tex]
Use Additive inverse.
[tex]t[/tex]
Hence, the sum is [tex]t[/tex].

Help please I’m almost done
Answer:
33 and -39
Step-by-step explanation:
Angle on a straight line = 180
|5x + 15| = 180 and |5x + 15| = -180
5x + 15 = 180
Subtract 15 from both sides;
5x = 165
Divide both sides by 5;
x = 33
5x + 15 = -180
Subtract 15 from both sides;
5x = -195
Divide both sides by 5;
x = -39

Answer:
Through pythogoras theorem
a^2+b^2=c^2
20^2+16^2=c^2
c^2=400+256
c^2= 656
c= square root of 656
c=25.6 inches or 30 inches
Missing side 25.6 inches or 30 inches
c^2 = a^2 + b^2
c^2 = 16^2 + 20^2
c^2 = 256 + 400
c^2 = 656
Now, square root both sides to find the missing length of c or the hypontenuse.
Answer: c = 25.6 inchesthe difference between 4 times more than 40 and 20

joseph is planting a garden. he plants 2 tomato plants for every 5 peppers. If joseph plants 14 tomato plants how many pepper plants does he plant?
Answer:
Ratio of tomato plant to that of pepper plant = 2:5
Let x be the number of pepper plants for 14 tomato plants.
Now, according to the question,
2:5 = 14:x
14×5 = 2x
x = 70/2 = 35 plants.
Step-by-step explanation:
So he/she would have 35 pepper plants to plant
Use the Distributive Property to solve the equation. -2(x + 4) = 8 Apply the Distributive Property and simplify. - 2x+ what = 8
Answer:
if your asking for the -2(x+4)=8 equation its -8
Hey there!
First, use the Distributive Property and distribute -2:
-2(x+4)=8
-2x-8=8
Add 8 to both sides:
-2x=8+8
-2x=16
Divide both sides by -2:
x=-8
Hope everything is clear.
Let me know if you have any questions!

What is the ratio of the length of one leg to the length of the other leg?
9514 1404 393
Answer:
D. 1 : 1
Step-by-step explanation:
The ratio of the two legs in any isosceles triangle is 1 : 1. That is also true of this isosceles right triangle. (You can tell it is isosceles because the acute angles are identical in size.)

Square ABCD has diagonals AC¯¯¯¯¯
and BD¯¯¯¯¯
. What is m∠ABD
A
180º
B
90º
C
45º
D
360º
Answer:
option (c)
Step-by-step explanation:
Given,
ABCD is a square.
AC and BD are diagonals
We know that,
Sides of the square make 90 degrees with each other.
And Diagonals bisect the opposite angles of the square.
Now,
[tex]\angle ABD = \dfrac{\angle ABC}{2}[/tex]
[tex]\angle ABC = 90^\circ[/tex]
[tex]\angle ABD = \dfrac{\angle ABC}{2}[/tex]
[tex]\angle ABD = \dfrac{90^\circ}{2}[/tex]
[tex]\angle ABD = 45^\circ[/tex]
Hence, option (c) is correct.

A 12-foot ladder is placed 4 feet away from a house as shown.
A 12 foot ladder is leaning against a house to form angle x. The distance between the house and the bottom of the ladder is 4 feet. The angle between the house and the ground is 90 degrees.
What is the value of x, rounded to the nearest degree?
x ≈
°
According to the manufacturer, if the angle the ladder forms with the ground, x, is between 70° and 75°, then it meets safety standards.
Is this ladder being used safely?
Answer:
Answer: x = 71 degrees. Yes, the ladder meets safety standards
Discussion:
The problem describes a right triangle with hypotenuse 12, the side against the ground is 4, and the angle between those two sides is "x". For this triangle,
cosx = (side adjacent to angle) / hypotenuse
= 4 / 12
= 1/3
To find "x" take the inverse cosine of each side to find that :
x is approximately 70.52 degrees. That's 71 degrees rounded to the nearest degree.
