Step-by-step explanation:
Let the equation of the line be y = mx + c
since the line is parallel to y = -1/2x + 1, the two lines have the same gradient.
therefore, m = -1/2
sub (-4, -1):
-1 = -1/2(-4) + c
c = -3
therefore equation of the line is y = -1/2x - 3

Which decimal number is equal to 3/18 ?
A. 0.167
B. 0.16¯
C. 0.16¯¯¯¯
D. 0.167¯¯¯¯¯
Answer:
Second option
Step-by-step explanation:
In order to find the answer to this question you have to divide the numerator into the denominator remembering that whole numbers have a secret decimal point to the right of itself.
[tex]\frac{3}{18}[/tex]
[tex]\frac{3}{18} =3\div18[/tex]
[tex]3\div18=0.16666666666[/tex]

There are 2 value's in a game. one of them is Pancake, the other is waffle. Pancakes are worth 1.5x a waffle. I have 10 waffles, how much Pancake value do I have?
Answer:
Approximately 6.67 pancakes.
Step-by-step explanation:
We can write an equation that relates the two items.
Let P represent Pancake and let W represent Waffle.
Pancakes are worth 1.5 times a Waffle. Therefore:
[tex]W=1.5P[/tex]
To find the Pancake value for 10 Waffles, we can substitute 10 for W and solve for P. Therefore:
[tex]\begin{aligned} W&=1.5P \\ 10&=1.5P \\ 6.\overline{6}&=P \end{aligned}[/tex]
Hence, 10 Waffles equates to approximately 6.67 pancakes.

Find the indicated values, where g(t)=t^2-t and f(x)=1+x g(f(2)+3)
Answer:
[tex]g(f(2)+3)=30[/tex]
Step-by-step explanation:
We have the two functions:
[tex]g(t)=t^2-t\text{ and } f(x)=1+x[/tex]
And we wish to find:
[tex]g(f(2)+3)[/tex]
First, let’s find f(2) first. So, we will substitute 2 for x for f(x):
[tex]f(2)=1+(2)=3[/tex]
Hence, we can now substitute 3 for f(2):
[tex]g(f(2)+3)=g(3+3)=g(6)[/tex]
Now, we can find g(6). Substitute 6 for t for g(t):
[tex]g(6)=(6)^2-(6)=36-6=30[/tex]
Therefore:
[tex]g(f(2)+3)=30[/tex]
Solve the inequality for x:

Answer:
x = 85°, y = 30°
Step-by-step explanation:
40° + x + 55° = 180°
x + 95° = 180°
x = 85°
85° + 65° + y = 180°
150° + y = 180°
y = 30°
If a couple has 3 children, what is the probability of all three children being girls? Justify.
Answer:
The probability of all three children being girls will Be: 1/8
Step-by-step explanation:
The couple has 3 children.
We have to determine the probability of all three children being girls.
As we know that for each child, the probability of being a girl is ' [tex]\frac{1}{2}[/tex] ' as is the probability of being a boy is ' [tex]\frac{1}{2}[/tex] '.
so for there to be all girls, the probability will be:
P ( all girls) = 1/2 × 1/2 × 1/2 = 1/8
Therefore, the probability of all three children being girls will Be: 1/8

A cab company charges $4 per cab ride, plus an additional $2 per mile driven. Write an equation that shows the relationship between the distance x and the cost y. Write your answer as an equation with y first, followed by an equals sign.
Answer:
y = 2x + 4
Step-by-step explanation:
So, the cab company charges a flat fee of $4 per cab ride, meaning 4 has no variables in the equation. Now, x is the distance, and the cab company charges $2 per mile driven. Per mile driven is a distance unit, so the x goes with the 2. From that, you can get that the cost is equal to 4 dollars plus 2x (2 times the distance in miles). This is y = 2x+4.

Determine whether the planes are parallel, perpendicular, or neither.8x + 8y + 8z = 1, 8x − 8y + 8z = 1 parallel perpendicular neither Correct: Your answer is correct.If neither, find the angle between them. (Round your answer to one decimal place. If the planes are parallel or perpendicular, enter PARALLEL or PERPENDICULAR, respectively.)
Answer:
The answer is "[tex]\bold{\theta= 70.53^{\circ}}[/tex]"
Step-by-step explanation:
The given value:
[tex]8x+8y+8z = 1\ and \ 8x-8y+8z = 1[/tex]
When the normal vectors are in the plane:
[tex]n_1 = < 8,8,8 > \ and \ n_2 = < 8, -8, 8>:[/tex]
Because the two variables really aren't proportional to each other and the wings are not parallel.
Let us just find that two vectors' dot product.
[tex]n_1 \cdot n_2 =<8,8,8> < 8,—8,8>\\\\ = 64-64+ 64 \\\\ = 64 \neq 0[/tex]
Therefore, we won't find that angle between both the given planes as parallel.
[tex]\cos \theta = \frac{n_1 \cdot n_2}{|n_1||n_2|}\\\\\cos \theta =\frac{64}{\sqrt{192} \sqrt{192}}\\\\\cos \theta =\frac{64}{8\sqrt{3} 8\sqrt{3}}\\\\\cos \theta = \frac{1}{3}\\\\ \theta = 70.53^{\circ}[/tex]
It is required to know the orientation of one plane relative to the other.
The angle between the planes is 70.5°.
PlanesThe given planes are
8x + 8y + 8z = 1
8x − 8y + 8z = 1
Parallel
[tex]\dfrac{8}{8}=\dfrac{8}{-8}=\dfrac{8}{8}\\\Rightarrow 1\neq -1\neq 1[/tex]
The planes are not parallel.
Perpendicular
[tex]8\times 8+8\times -8+8\times8=64\neq 0[/tex]
The planes are not perpendicular as dot product is not 0.
Finding angle
[tex]\theta=\cos^{-1}\dfrac{8\times 8+8\times -8+8\times8}{\sqrt{8^2+8^2+8^2}\sqrt{8^2+(-8)^2+8^2}}\\\Rightarrow \theta=\cos^{-1}\dfrac{1}{3}\\\Rightarrow \theta=70.53^{\circ}[/tex]

What is the area of the figure?
Answer: 17.5 square yards
================================================
Work Shown:
base = 5 yards
height = 7 yards
The base and height are always perpendicular to one another
area of triangle = 0.5*(base)*(height)
area of triangle = 0.5*(5)*(7)
area of triangle = 17.5 square yards
