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.

• 20 hydrogen
• 26 oxygen
and among the products,
• 8 carbon
• 16 + 10 = 26 oxygen
• 20 hydrogen
Answer:
Simple Answer... Yes it is balanced.

The graph of g(x) goes through the point (-4, 1) and is parallel to h(x) = 5x - 2 points
8. Determine the symbolic representation of g(x). Express your answer in
slope intercept form. *
Answer:
[tex]g(x)=5x+21[/tex]
Step-by-step explanation:
The slope of g(x) is 5 because the slope of h(x) is 5 and g is parallel to h.
In point-slope form:
[tex]g(x)-1=5(x+4)[/tex]
Rearranging for slope intercept form:
[tex]g(x)-1=5x+20\\g(x)=5x+21[/tex]
The m∠4 = 5x - 3° and m∠5 = 3x + 17°. Find the value of x.

this is all i ask, just please give me the answer
Answer:
92
Step-by-step explanation:
161 divided by 7 is 23. so you just multiply 4 by 23. And that gets you the answer. Hope this helps:)
Answer:
x=92
Solve for x by simplifying both sides of the equation, then isolating the variable. hopes this helps have a great day <3 :)
Which calculation will ALWAYS give a result greater than 1? A.8/9 × a number less than 1 B.1 2/5 − a fraction less than 25 C. 7 × a number less than 1 D.3/7 + a fraction less than 1/2
Answer: B.1 2/5 − a fraction less than 2/5
Step-by-step explanation:
Question was not formatted properly and in the proper format, the above is the answer.
1²/₅ - ²/₅ = 1
Any number therefore that is lower than ²/₅ will when subtracted from 1²/₅ give an answer greater than 1 because when ²/₅ was subtracted from 1²/₅, it gave 1 as an answer.

PLEASE I NEED HELP WITH THIS ANSWER
Answer:
a) x = -2/3 y = -26/3 or -8 2/3
b) x = 12 y = 5
Step-by-step explanation:
a) since both equations begin with 'y =' you can set them equal to each other
4x - 6 = x - 8
3x = -2
x = -2/3
sub x value to find y:
y = 4(-2/3) - 6
= -8/3 + (-18/3)
= -26/3
19. Find the equation of the line that contains the given points. Write the equation in slope-
intercept form, if possible.
(-5,-5) and (1,7)
Please solve step by step
Answer:
y = 2x +5
Step-by-step explanation:
1. use slope intercept for y2 - y1 / x2 - x1 --> 7-(-12) / 1-(-5)
2. solve --> 7-(-12) / 1-(-5) = 2
3. put in slope (2) and a coordinate into equation --> y = mx + b --> 7 = 2(1) + b
4. solve --> 7 = 2(1) + b --> b = 5
5. put the equation together --> y = 2x + 5

A square of side 72 cm and a rectangle of length 90 cm have same perimeter. Find the difference in areas ?
A)216cm2
B)304cm2
C)324cm2
D)328cm2
Answer:
324 cm²
Step-by-step explanation:
→ Work out perimeter of square
72 + 72 + 72 + 72 = 288
→ Work out the width of the rectangle
288 - (90 × 2) = 108
108 ÷ 2 = 54
→ Work out area of square
72 × 72 = 5184 cm²
→ Work out area of rectangle
90 × 54 = 4860 cm²
→ Minus the areas from each other
5184 cm² - 4860 cm² = 324 cm²
Answer:
C) 324cm²
Step-by-step explanation:
1) they have the same perimeter so to find it you add all four sides of the square because they are all the same ( 72+72+72+72=288)
2) now you multiply 90 by 2 because the rectanglehas to sides of the same length(90×2=180) the answer you get you are going to subtract to 288 (288-180=108)
3) now divide 108 by 2 (108÷2= 54) the answer you get equals the width of the side of the rectangle
4) to get the area of the rectangle you multiply 54 with 90 (54×90=4,860) to get the area of the square you multiply 72 times 72 (72×72=5,184)
5) now you subtract 5,184 and 4,860 ( 5,184-4,860= 324cm²)

The area of a square mural pointed on the side of a building is 110 square feet. What is the best estimate of the side length of the mural?
A.10 Feet
B.10.2 Feet
C.10.5 Feet
D.10.8 Feet
Answer:
C
Step-by-step explanation:
Area of a square equals to the square of its side, therefor the side of a given area for a square is the square root of the area.
[tex]A = a^{2}\\a = \sqrt{A}\\a = \sqrt{110} = 10.48 ft[/tex]

what is the volume of this figure ?
A) 3x2x6
B)6x8x2
C)8x2x3
D)3x2x8x6
Answer:
Step-by-step explanation:
since the hypotenuse of 6 cm is shorter than the base of 8 cm there is something wrong with this drawing. The box can't be square so maybe answer C is good but.. since this box isn't a right angled box.. we really don't know. This is a bad question b/c it's making the appearance of being a right angle but it can not be. Like an Escher drawing.. not possible irl
The volume of the rectangular prism is 8×2×3 cubic in or 48 cubics in option (B) 8×2×3 cubic in is correct.
What is a rectangular prism?It is defined as the six-faced shape, a type of hexahedron in geometry.
It is a three-dimensional shape. It is also called a cuboid.
The missing height of the rectangular prism is 3 cm
It is given that:
The rectangular prism is shown in the picture with dimensions.
As we know, the volume of the rectangular prism is given by:
V = length×width×height
Length = 2 cm
Width = 8 cm
Height = 3 cm
The volume of this figure:
V = 2×8×3
Or
The volume of this figure V = 8×2×3 cubic in
Thus, the volume of the rectangular prism or the volume of the figure is 8×2×3 cubic in or 48 cubics in option (B) 8×2×3 cubic in is correct.
