Answer:
k = 3.33
Step-by-step explanation:
x = 2
y = 3
x - ky + 8 = 0
2 - k(3) + 8 = 0
2 - 3k + 8 = 0
10 - 3k = 0
-10 -10
-3k = -10
k = 3.33
Answer:
x−ky+8=0=k=x/y+8/y
k=2/3+8/3 =3.266

What is m<2 + m<3?
it says my question has to be longer so yk im just making it longer but ignore this
90°, because angle m<1 is 90.
Answer:
m < 2 + m < 3 = 90°
Step-by-step explanation:
90° = m < 2 + m < 3 ( exterior angle of a triangle is equal to the sum of two opposite interior angle )
Ramon earns $1670 each month and pays $53.00 on electricity. To the nearest tenth of a percent, what percent of Ramon's earnings are spent on electricity each month?
Answer:
the percentage of the ramon earnings spent on electricity is 3.17%
Step-by-step explanation:
The computation of the percentage of the ramon earnings spent on electricity is shown below:
= Pays for electricity ÷ earnings per month
= $53 ÷ $1,670
= 3.17%
Hence, the percentage of the ramon earnings spent on electricity is 3.17%

Answer:
[tex]\Huge\boxed{x=8}\\\\\Huge\boxed{y=138}[/tex]
Step-by-step explanation:
Hello There!
Knowing that the sum of the angles in a triangle is 180
we can use this equation to solve for x
180 = 90 + 5x + 2 + 6x
Step 1 combine like terms
90 + 2 = 92
5x + 6x = 11x
now we have
180 = 11x + 92
step 2 subtract 92 from each side
180 - 92 = 88
92 - 92 cancels out
now we have
88 = 11x
step 3 divide each side by 11
11x/11 = x
88/11 = 8
we're left with x = 8
Now we plug in 8 into x for 5x + 2 so we can solve for y
5*8=40
40+2 = 42
Now we can solve for y
the angle measured 42 degrees and the angle labeled y are supplementary angles meaning that the sum of the two angles is 180
so to find y we subtract the given angle (42) from 180
180 - 42 =138 so we can conclude that y = 138
Notes: the little square represents a right angle which has a measure 90 degrees so thats where the 90 came from .

What is the sum of -64/5 and 64/5 ?
Answer and Explanation
0This is because they are both the same opposite number, and you are adding.
But, if it was, [tex]\frac{64}{5}+\frac{64}{5}[/tex] then it would be [tex]25.6[/tex] or [tex]\frac{128}{5}[/tex].
So, the answer is 0.

Find the LCM
of 9 and 27.
Answer:
27
Step-by-step explanation:
The answer is 27, because 9 x 3 = 27 and the smallest number that is the same is 27.
Hope this helps!
Answer:
27
Step-by-step explanation:
LCM is the least common multiple of one or more numbers. we can find this by finding the factors of 9 and 27.
9, 18, 27, 36, 45, 54
27, 54, 81, 108
since 27 is the smallest factor of both 9 and 27, it is the least common multiple.

What is the surface area of the box if it is scaled up by a factor of 10?
the surface area is 206 in, width 9 in, length 13 in, height 4 in
(first to answer gets brainly please need answer quick!)
Answer:
6l², where l is the length of one side.
If the side is increased 10 times,
6(10l)²
=100 x6l²
The surface area increases 100 times. Thus, the new surface area is
272 * 100
= 27,200 sq in

Solve the inequality. 3/4x−2/3≤5/6 Choose the solution that is graphed on this number line.
Answer:
x ≤ 2
(when graphed, closed circle on two, shaded to the left)
Step-by-step explanation:
3/4 x - 2/3 ≤ 5/6
Add 2/3 to both sides:
3/4x ≤ 5/6 + 2/3
3/4x ≤ 3/2
Divide by 3/4 on both sides:
x ≤ 3/2 ÷ 3/4
x ≤ 2

The scatter graph for level of water in a dam on each day and date for one month type of data is most likely to suggest a linear association.
What is scatter plot?A scatter plot, like a scatter chart or graph, employs dots to represent the values of two numerical variables. The horizontal value represents the data from individual points. Hence, it is used to observe the relationships between variables.
The scatter plot can provide the values for the data set. The points can be of various sizes, colours, and forms. The information is presented in the form of points.
The values are represented on the vertical axis. The data association can be positive, negative, or neutral. A mosaic and a fluctuational diagram can be displayed on the scatter plot.
Thus, the plot which can be linear association form level of water in a dam on each day and date for one month

A diameter of a circle has enpoints (-2, 10) and (6, -4) in the standard (x, y) coordinate plane. What is the center of the circle?
Answer:
The center of the circle is [tex]C(x,y) = (2, 3)[/tex].
Step-by-step explanation:
The center of the circle is the midpoint of the segment between the endpoints. We can determine the location of the center by this vectorial expression:
[tex]C(x,y) = \frac{1}{2}\cdot R_{1}(x,y)+ \frac{1}{2}\cdot R_{2}(x,y)[/tex] (1)
Where:
[tex]C(x,y)[/tex] - Center.
[tex]R_{1} (x,y)[/tex], [tex]R_{2} (x,y)[/tex] - Location of the endpoints.
If we know that [tex]R_{1} (x,y) = (-2,10)[/tex] and [tex]R_{2} (x,y) = (6,-4)[/tex], then the location of the center of the circle is:
[tex]C(x,y) = \frac{1}{2}\cdot (-2,10)+\frac{1}{2}\cdot (6,-4)[/tex]
[tex]C(x,y) = (-1, 5) + (3, -2)[/tex]
[tex]C(x,y) = (2, 3)[/tex]
The center of the circle is [tex]C(x,y) = (2, 3)[/tex].

Answer:i think it is 5
Step-by-step explanation:
Which of the following represents the distance between the y-intercept and x-intercept of the line whose equation is y = 3x + 12?
1) square root 120
2) square root 160
3) square root 200
4) square root 244
Answer:
√160
Step-by-step explanation:
For y-intercept, we use y = mx + c. Comparing both, y = mx +c & y = 3x + 12
y intercept = c = 12
Point is (0, 12)
For x intercept, we use y = m(x - d). We have
y = 3x + 12 → y = 3(x - (-4))
Compare both, x intercept = d = - 4
Point is (-4, 0)
Using distance formula,
Distance = √(0-12)² + (-4-0)² = √12²+4²
Distance = √144+16 = √160
.
10. Solve for all values of x algebraically (find the zeroes):
3x^2 +12x – 7 = x^2+ 3x – 2
Answer:
x = -5 or 1/2
Step-by-step explanation:
From the question,
3x²+12x-7 = x²+3x-2
Collect like terms
3x²-x²+12x-3x-7+2 = 0
2x²+9x-5 = 0
Using factorization method to solve the quadratic equation
2x²+10x-x-5 = 0
(2x²+10x)-(x+5) = 0
2x(x+5)-1(x+5) = 0
(x+5)(2x-1) = 0
Either,
x+5 = 0
x = -5
or,
2x-1 = 0
2x = 1
x = 1/2.
Therefore,
x = -5 or 1/2

Answer:
Step-by-step explanation:
18/14 and 10/15 don't have the same value. Only equivalent fractions have same value.
These two are not equivalent fractions
Answer:
No.
Step-by-step explanation:
Without much calculation, we can notice that 18/14 is actually greater than 10/15 since its numerator is greater than its denominator, making it greater than 1. However, 10/15 is less than 18/14 since its numerator is less than its denominator making it less than 1. In short:
18/14 > 1
10/15 < 1
18/14 > 10/15
