Answers
Answer:
part 1:
1) AB = BC = 10
2) DE = sqrt(10² - 9²) = sqrt(19)
3) CED = 90⁰
4) BCD = (90⁰ - 53⁰).2 = 74⁰
part 2:
because FGHJ is a rhombus
=> GK = KJ
<=> 3x + 1 = x + 9
<=> 2x = 8
<=> x = 4
and we have:
GHK + FGK = 90⁰
<=> (4y - 8)/2 + y + 4 = 90⁰
<=> 2y - 4 + y + 4 = 90⁰
<=> 3y = 90⁰
<=> y = 30
5) with x = 4 => GJ = 2KJ = 2.(4 + 9) = 26
6) JK = 4 + 9 = 13
7) with y = 30, HFJ = 90 - FGK = 90 - 34 = 56⁰
8) HJF = 2.FGK = 2.34 = 68⁰
part 3:
because MNLO is rectangle
=> MP = PO
<=> 5a - 7 = 2a + 8
<=> 3a = 15
<=> a = 5
9) with a = 5, MO = 2.PO = 2.(2.5 + 8) = 2.18 = 36
10) NP = PO = 2.5 + 8 = 18
11) LM² = LN² - MN² = MO² - 26² = 36² - 26² = 620
=> LM = 2sqrt(156) = 24,9
12) tan NMO = NO/MN = LM/MN = 24.9/26
=> NMO = 43,8⁰
part 4:
because RSTU is square
=> SR = RU
=> 2k + 7 = 3k - 2
<=> k = 9
with k = 9 =>RU = SR = 2.9 + 7 = 25
13) RV = 1/2.SU = 1/2.sqrt(25² + 25²) = 17,7
14) SU = 2RV = 2.17,7 = 35,4
15) perimeter RSTU = 25.4 = 100
16) area RSTU = 25² = 625

Answers
Answer:
The true statements are;
A. The point (0, -3) is on the line
C. The point (-6, -6) is a point on the line
Step-by-step explanation:
The question relates to the finding of the equation of a straight line graph
The x-intercept of the graph is (6, 0) and the graph passes through the point (2, -2)
Therefore, the slope of the graph is m = (-2 - 0)/(2 - 6) = 0.5
The equation of the graph in point and slope form is given as follows;
y - 0 = 0.5 × (x - 6)
∴ y = 0.5·x - 3
Therefore, the equation of the graph in slope and intercept form, y = m·x + c is also y = 0.5·x - 3
A. The y-intercept of the graph is (0, -3), therefore, the point (0, -3) is on the line
B. The equation of the graph, y = 0.5·x - 3, can be written as follows;
8·y = 8 ×0.5·x - 8 × 3 = 4·x - 24
∴ 8·y - 4·x = -24
C. When y = -6, 'x' is given as follows;
y = 0.5·x - 3
-6 = 0.5·x - 3
0.5·x = -6 + 3 = -3
x = -3/0.5 = -6
x = -6
Therefore, when y = -6, x = -6, and (-6, -6) is a point on the line
D. When x = 0, 'y', is given as follows;
y = 0.5·x - 3
When x = 0, y = 0.5 × (0) - 3 = -3
Therefore the point (0, -3) is on the line and the point (0, -4) is not on the line
E. The point (-6, 0) represent an x-intercept of a line graph, however the x-intercept on the given line is (6, 0) and when y = 0 on the line, x = 6
Therefore, the point (-6, 0) is not on the line
F. The equation of the graph is 8·y - 4·x = -24, therefore, - 4·x + 8·y = 24 does not represent the equation of the graph

Step-by-step explanation:
(x - 4)(x + 4)
Each term in the second factor is multiplied by each term in the first factor, that is
x(x + 4) - 4(x + 4) ← distribute both parenthesis
= x² + 4x - 4x - 16 ← collect like terms

Answers
Answer:
infinite solutions
Step-by-step explanation:
At first, we try to isolate the x, but adding 4 to -4 on both sides. Both sides have a -4 so it cancels out on both sides of the equation. Similarly, both sides also have a positve 6x, so when we subtract 6x from 6x we get 0. After simplification, we get x = x; x can be any number [ex. 1=1, 2=2, 3=3,etc.], therefore any number can fit into this equation
6x - 4 = -4 + 6x
6x - 4 + 4 = -4 + 4 +6x
6x = 6x
x = x

Et of y=x2-4 and + y + 2 = 0?
Answers
The equation y = x2 – 4 + y + 2 = 0 can be solved by completing the square.
What is equation?An equation is a mathematical statement that to express our equal. Is consist of two expression separated by an equal sign and can contain numbers, variables and operators. Equation get be used to solve problems make prediction and describe relationship between different quantities. Equation can be can also be used to represent physical laws and other phenomena.
First, subtract y from both sides of the equation to get x2 - 4 + 2 = y. Then, subtract 2 from both sides of the equation to get x2 - 6 = y. Finally, add 9/4 to both sides of the equation to get (x - 3/2)2 = 9/4 + y.
This equation can be solved by taking the square root of both sides to get x - 3/2 = ±√(9/4 + y). Finally, add 3/2 to both sides of the equation to get x = 3/2 ±√(9/4 + y).
