3. Which of the given equations are not linear? How are these equations
differ from linear equations?
Answer:
Step-by-step explanation:
the equation which are not linear is which it does not form a straight line but forms a curve.
Answer: A linear equation is when a line on a graph isn’t straight or does not meat the origin or forms a curved line.
Step-by-step explanation:
Write and solve an equation to find the value of x and the missing angle measures.
Solve for q.
q/4 + 14
= 18
q =
Answer:
16
Step-by-step explanation:
q/4 + 14 = 18
q/4 + 14 - 14 = 18 - 14
q/4 = 4
q/4 x 4 = 4 x 4
q = 16
Answer:
q = 16
Step-by-step explanation:
Subtract 14 from each side, so it now looks like this: [tex]\frac{q}{4} = 4[/tex] Multiply each side by 4 to cancel out the 4 under q. It should now look like this: q = 16I hope this helps!
what is the answer? pls help
i'm not sure
Answer:
I don't think It is a line.
Step-by-step explanation:
The point A has coordinates (-1, 6) and the point B has coordinates (7, 2).
i Find the equation of the perpendicular bisector of AB, giving your answer in the form y = mx + c.
ii A point C on the perpendicular bisector has coordinates (p, q). The distance OC is 2 units, where O is
the origin. Write down two equations involving p and q and hence find the coordinates of the possible
positions of C.
Answer:
a) y = 2x -2
b) Equation: q = 2p - 2 ----(1)
p² + q² = 4 ----(2)
The coordinates of C may be (0, -2) or (6/5, 8/5)
Step-by-step explanation:
a) Step 1: Find the coordinates of midpoint, P of AB
x-co-ordinate of P = (x₁ + x₂)/2 = (-1 + 7)/2 = 3
y- co-ordinate of P = (y₁ + y₂)/2 = (6 + 2)/2 = 4
Step 2: Determine the gradient, m₂ of perpendicular bisector of AB
For perpendicular lines, m₁ * m₂ = -1 where m₁ is slope of AB
m₁ = (2 - 6)/(7 - -1) = -4/8 = -1/2
-1/2 * m₂ = -1
m₂ = 2
Step 3: Deriving the equation of the perpendicular bisector in the form y = mx + c
y - y₁ = m(x - x₁); substituting the values of the midpoints of the line
y - 4 = 2(x - 3)
y - 4 = 2x - 6
y = 2x -2
b) Step 1: Derive the values of the p and using the formula of distance between two points:
y = 2x - 2
therefore q = 2p - 2 ----(1)
OC = √(x₂ -x₁)² + (y₂ - y₁)²
2 = √(p - 0)² + ( q - 0)²
2 = √p² + q²
squaring both sides
p² + q² = 4 ----(2)
Substituting (1) in (2)
p² + (2p - 2)² = 4
p² + 4p² - 8p + 4 = 4
5p² - 8p = 0
p(5p - 8) = 0
Therefore p = 0 or 5p - 8 = 0
p = 0 or p = 8/5
Substituting p = 0 in (1)
q = -2
substituting p = 8/5 in (1)
q = 2(8/5) - 2
q = 16/5 - 2
q = 6/5
Hence the coordinates of C may be (0, -2) or (6/5, 8/5)

Select the locations on the number line to plot the points 10/2 and 9/2
Answer:
Well, 10/2 is actually 5, so the first point would be at 5 on the number line. -9/2 is -4 1/2 as a mixed number. So, the point for -9/2 would be on the right of -5.

Find the derivative of log e^((1+tan x)) w.r.t x
Determine the quotient
Answer:
option 2: [tex]\large \frac{10}{12}[/tex]
Step-by-step explanation:
when dividing fractions, you can actually multiply them together by the reciprocal of the second one. (reciprocal is just flipping the fraction)
so, [tex]\frac{2}{3}[/tex] ÷ [tex]\frac{4}{5}[/tex]
becomes [tex]\frac{2}{3} * \frac{5}{4}[/tex]
to multiply fractions together, just multiply the top and bottom.
2 * 5 = 10
3 * 4 = 12
so the answer would be [tex]\frac{10}{12}[/tex]

Step-by-step explanation:
what is the value of k?
Answer:
(4k+5)+ (6k+10) = 115
Exterior angle of a triangle is equal to the sum of two opposite interior angles
10k=15=115
10k= 100
k = 100/10
k = 10
Step-by-step explanation:
Answer:
k = 10
Step-by-step explanation:
The 3rd angle that's not defined in the equation is supplementary to 115, so the angle is 180-115 = 65.
We can solve for the equation 65+(4k+5)+(6k+10)=180 -> 65+4k+5+6k+10=180 -> 10k+80 = 180 -> 10k = 100 -> k = 10.
To double-check(optional), we can plug k back into the equation, so 65 + 4*10 + 5 + 6*10 + 10 = 180 -> 100 + 65 + 5 + 10 = 180 -> 180 = 180, so we can confirm that k = 10.
Heeeeeeeeeeeeeeeeeeeeelllllllllllllppppppppppp
Answer:
You should add both sides by 1 to isolate the variable first.
To continue solving, divide both sides by -7 and you end up with p = -2.

A certain blueprint shows two fences. Fence A is 1 1/5 yards long but is 1 1/2 inches long on the 2 blueprint. What is the unit rate for inches per yard on this blueprint? If fence B is 4 yards long, how long is fence B on the blueprint?
Answer:
Unit rate = 1.25 inches per yard
Length of fence B on the blueprint = 5 inches
Step-by-step explanation:
We are told that Fence A is 1 1/5 yards long but is 1 1/2 inches long on the blueprint.
This means it's 1.2 yards long but 1.5 inches on the blueprint.
Thus, the unit rate for this blueprint will be; 1.5/1.2 = 1.25 inches per yard
fence B is 4 yards long.
Thus, the corresponding blueprint measurement = 4yards × 1.25 inches/yard = 5 inches.
Given A(-3, 8), find the coordinates of the point B such that C(5, -8) is the midpoint of segment AB.

The concept of determining which reactant is limiting and which is in excess is akin to determining the number of sandwiches that can be made from a set number of ingredients. Assuming that a cheese sandwich consists of 2 slices of bread and 3 slices of cheese, determine the number of whole cheese sandwiches that can be prepared from 44 slices of bread and 69 slices of cheese. number of sandwiches: 22 Which of the two ingredients limits the number of sandwiches that can be made
Answer:
SLICE OF BREADStep-by-step explanation:
If a cheese sandwich consists of 2 slices of bread and 3 slices of cheese, in order to determine the number of whole cheese sandwiches that can be prepared from 44 slices of bread and 69 slices of cheese, we will use the equality postulate as shown;
1 cheese sandwich = 2 slices of bread
x cheese sandwiches = 44 slices of bread
cross multiply
2 * x = 1 * 44
2x = 44
divide both sides by 2
2x/2 = 44/2
x = 22
Similarly;
1 cheese sandwich = 3 slices of cheese
y cheese sandwiches = 69 slices of cheese
cross multiply
3 * y = 1 * 69
3y = 69
divide both sides by 3
3y/3 = 69/3
3y = 23
Since both values of x and y are greater than or equal to 22 hence 22 sandwiches can be prepared from 44 slices of bread and 69 slices of cheese.
Since the amount of cheese sandwiches made from slices of bread (22) is not up to that made from slices of cheese (i.e 23), hence the ingredient that limits the number of sandwiches that can be made is the slice of bread
