Answer:
4.68
Step-by-step explanation:
solve the simultaneous equation
2x - 5y = 9
3x + 4y = 2
Answer:
x = 2, y = -1.
Step-by-step explanation:
2x - 5y = 9
3x + 4y = 2
Multiply first equation by -3 and the second by 2:
-6x + 15y = -27
6x + 8y = 4 Adding the 2 equations:
23y = -23
y = -1.
Now substitute this value for y in the first equation:
2x - 5(-1) = 9
2x = 9 +5(-1)
2x = 9 - 5
2x = 4
x = 2.
What are the coordinates of the point on the directed line segment from (−8,−6) to (-1, 8) that partitions the segment into a ratio of 5 to 2?
Answer:
(-3, 4)
Step-by-step explanation:
let the point P(x, y)
x = (5/7 × (-1+8)) + (-8)
= (5/7 × 7) -8 = 5-8 = -3
y = (5/7 × (8+6)) + (-6)
= (5/7 × 14) -6 = 10-6 = 4
so, P => (-3 , 4)

Find the value of x
Use sin, cos, or tan
=========================================================
Explanation:
We use cosine to tie together the adjacent and hypotenuse
cos(angle) = adjacent/hypotenuse
cos(38) = x/21
21*cos(38) = x
x = 21*cos(38)
x = 16.5482258257411
x = 16.5

In order for the data in the table to represent a linear
function with a rate of change
of -8, what must be the
value of a?
O a= 2
O a = 3
A
O a = 19
O a = 35
Answer:
a = 19
If the rate of change is -8, everytime you do up for x you will minus 8. For example, x = 10 so y = 27 ; x=11 so y = 27-8 = 19 ; x = 12 so y = 19-8 = 11.
Therefore, when x is 11; y is 19

Which of the following theorems verifies that AHIJE AKLM? H K M ОА. НА O O O B. LA O C. HL O D. AA
===================================
Explanation:
HA = hypotenuse angle
The tickmarks tell us that the hypotenuse IJ is the same length as the hypotenuse LM. So that's the "hypotenuse" portion of "HA".
The "angle" portion refers to the acute angles HIJ and KLM being the same measure, as shown by the curved arc marking. We aren't referring to the right angles because the HA theorem can only be used for right triangles, so that means the right angle is already built into it (and we can ignore the right angles).
Notice how HA is a special case of AAS.
- Find the length of the arc. Use 3.14 for Tl.
Answer:
Solution given;
angle =270°
radius [r]=8cm
we have
length of arc =270°/360°×2×π*r
=270°/360°×2×3.14*8=37.68cm
length of the arc is 37.68cm.
Triangle ABC is going to be reflected over the line y = X.
If A is located at (1,-7), where will A' be located?
Answer:
(-7, 1)
Step-by-step explanation:
Coordinate rules :]
Reflection over x-axis -- (x, y) -> (x, -y)
Reflection over y-axis -- (x, y) -> (-x, y)
Reflection over y = x -- (x, y) -> (y, x)
Reflection over y = -x -- (x, y) -> (-y, -x)
Andy is fishing from a small boat. A fish swimming at the same depth as the hook at the end of his fishing line is 12 meters away from the hook. If Andy is 15 meters away from the fish, how far below Andy is the hook?
Answer:
27 meters
Step-by-step explanation:
Given
[tex]Fishing\ Line =12m[/tex] ----- from hook
[tex]Andy =15m[/tex] ---- from the fishing line
Required
Distance between Andy and the hook
The scenario can be represented as:
Hook ----------------------- Fishing Line ----------------------------- Andy
Using the above representation, the distance (d) between Andy and the hook is:
[tex]d = Andy + Fishing\ Line[/tex]
[tex]d = 15m + 12m[/tex]

Which is the length of the building's wall brace?
A. 14.45 m
B. 17 m
C. 23 m
D. 49 m
E. 189 m
Answer:
A) 14.45 m is the answerrrerreer
Answer:
17m
Step-by-step explanation:
We can use the Pythagorean theorem
a^2+b^2= c^2 where a and b are the legs and c is the hypotenuse
8^2 + 15^2 = c^2
64+ 225 = c^2
289 = c^2
Taking the square root of each side
sqrt(289) = sqrt(c^2)
17 =c
Point k is on line segment JL. Given JL = 4x+2, KL = 5x-6, and JK = 3x, determine the numerical length of JK.
Answer:
6 units
Step-by-step explanation:
JK + KL = JL
3x + 5x-6 = 4x+2
8x-6 = 4x+2
subtract 4x from each side to get:
4x - 6 = 2
add 6 to each side to get:
4x = 8
x = 2
JK = 3x and x=2 so JK = (3)(2) or 6
The numerical length of JK = 6
What is Line Segment?
" A line segment is a line section that can link two points. "
We know that point K is divide line JL
Given that JL = 4x+2
KL = 5x-6
JK = 3x
So, Equation is JK+KL = JL
3x+5x-6 = 4x+2
8x-6 = 4x+2
8x-4x = 2+6
4x = 8
x = 8/4
x = 2
So , numerical length of JK = 3x
JK = 3×2
JK = 6
Hence , length of JK is 6
