Answer:
No solution for x, when k = 1x = 68/(k - 1), when k≠ 1Step-by-step explanation:
Given the equation
kx – 17 = 51 + x, where k = 1,Solve for x:
1*x - 17 = 51 + xx - 17 = x + 51x - x = 51 + 170 = 68,Incorrect equation, no solution for x when k=1
Solving for x when k ≠ 1
kx - 17 = 51 + xkx - x = 51 + 17x(k - 1) = 68x = 68/(k - 1)Write the equation of the line that passes through the point (-3, 5) and has a slope of
7.
Answer:
m=7
X1= -3
Y1=5
Y-Y1=m(X-X1)
Y-5=7(X-(-3))
Y-5=7(X+3)
Y-5=7X+21
Y=7X+21+5
Y=7X+26

An intercepted arc has a length of 19 yards. If the radius is 4 yards, find the measure of the central angle in radians and degrees.
The length of an arc is the distance between the endpoints of the arc.
The central angle is: [tex]\mathbf{4.75\ rad}[/tex] or [tex]\mathbf{272.16^o}[/tex]
The given parameters are:
[tex]\mathbf{l = 19yd}[/tex] --- length of the arc
[tex]\mathbf{r = 4}[/tex] -- radius of the circle
The length of an arc is calculated as:
[tex]\mathbf{l =r\theta}[/tex]
Divide both sides by r
[tex]\mathbf{\theta = \frac lr}[/tex]
Substitute known values
[tex]\mathbf{\theta = \frac{19}4}[/tex]
[tex]\mathbf{\theta = 4.75\ radians}[/tex]
Convert to degrees as follows:
[tex]\mathbf{\theta = 4.75 \times \frac{180}{\pi}}[/tex]
[tex]\mathbf{\theta = 4.75 \times \frac{180}{3.142}}[/tex]
[tex]\mathbf{\theta = 272.16^o}[/tex]
Hence, the central angle is: [tex]\mathbf{4.75\ rad}[/tex] or [tex]\mathbf{272.16^o}[/tex]

you will get 3y=12+6=18
3y=18
y=6
now replace y=6
3x+12=6
3x=6-12
3x=-6
x=-2
(-2,6)
Answer:
(-2,6)
Step-by-step explanation:
3x + 2y = 6
-3x + y = 12
3x + -3x = 0
2y + y = 3y
6 + 12 = 18
3y = 18
3y/3 = 18/3
y = 6
-3x + y = 12
-3x + 6 = 12
-3x = 12 - 6
-3x = 6
-3x/-3 = 6/-3
x = -2

C. $14.35
D. $11.85
Answer:
Her change would be $5.65
Step-by-step explanation:

Last night, the temperature fell from 0°F to -13 in 4 § hours. What was the average temperature change per hour? Solve the division problem. 2 1 -13= - 4 5 5 The temperature drop per hour can be represented by I °F. QUICKLY
Answer:
3.25 degrees/hour
Step-by-step explanation:
Last night, the temperature fell from 0°F to -13°F in 4 hour.
We need to find the average temperature change per hour. It can be calculated by dividing the change in temperature per unit time.
Change in temperature = -13°F -0°F = -13°F
So,
[tex]C=\dfrac{-13}{4}\\\\=-3.25\ \text{degrees/hour}[/tex]
So, the change in temperature is 3.25 degrees/hour.
Answer:
-3.25 degrees an hour
Step-by-step explanation:
-13 ÷ 4 = -3.25

A. 9
B. 8
C. 7
D. 6
Answer:
C
Step-by-step explanation:
The 2 triangles are similar (AA postulate ), thus the ratios of corresponding sides are equal, that is
[tex]\frac{14}{2}[/tex] = [tex]\frac{49}{x}[/tex] ( cross- multiply )
14x = 98 ( divide both sides by 14 )
x = 7 → C

Does bin width matter when it comes to histograms? Why or why not?
Answer:
Avoid histograms with small bin widths that group data into lots of bins. A histogram constructed with small bin widths will show the distribution as a “pancake.” so no it does not help us see the pattern in the data.

Answer: x = 8/4 = 2
12(2) + 4(6) = 24 + 24 = 48 = 6*8
Step-by-step explanation:
$12X + $6(4) = (X+4)*$8
12X + 24 = 8(x+4)
12x + 24 = 8x + 32
12x + 24 - 8x - 32 = 0
4x - 8 = 0
4x = 8
x = 8/4 = 2

z = 106
y = 74
Since angle 74 and angle y are the same sizes, you can know for a fact they are the same measurments. Next, you would do 74(2) and that would get you 148. 360 - 148 is 212. 212/2 is 106. TADAAAAA. That's the answer.
