A student would write an equation such as 2x + 38 = 90 for which set of angles?
S
Such as 2x + 38 = 180 for ubic
Answer:
Figure (c)
Step-by-step explanation:
a). Angles in the figure attached are the linear pair of angles.
Since, sum of the linear pair of angles is 180°.
2x + 38 = 180°
b). Angles given in this figure are the vertically opposite angles.
Since, vertically opposite angles are equal in measure.
2x = 38°
c). There are three angles given the picture.
Since these angles are formed at a point of a line, sum of angles will be 180°.
90° + 38° + 2x = 180°
2x + 38 = 180 - 90
2x + 38 = 90°
Therefore, figure (c) shows the equation.
Answer:
c

Make a conjecture. How are rigid transformations and congruent figures related? Check all that apply.
Rigid transformations preserve segment lengths and angle measures.
Rigid transformations produce congruent figures.
If two figures are congruent, then there is a rigid transformation or a combination of rigid transformations that will map one onto the other.
Answer:
Rigid transformations preserve segment lengths and angle measures.
Rigid transformations produce congruent figures.
If two figures are congruent, then there is a rigid transformation or a combination of rigid transformations that will map one onto the other.
Step-by-step explanation:
A rigid transformation or an isometry is a transformation that does not change the sides and angle of plane figures.Reflection in the plane, translations and rotation or a combination of them produce images that are congruent to the preimage.This implies that, two figures are congruent if and only if a rigid transformation or a combination of one or more rigid transformations will map one plane figure onto another.Therefore all the given options are true.All of the answers are correct, meaning that A,B, and all true.
The phone company B-Mobile has a monthly cellular plan where a customer pays a flat fee for unlimited voice calls and then a certain amount per GB of data used. If a customer uses 8 GB, the monthly cost will be $48. If the customer uses 38 GB, the monthly cost will be $108. A) Find an equation in the form y = m x + b , where x is the number of GB of data used in a month and y is the total monthly cost of the B-Mobile plan.

A shop owner can buy two televisions and three DVD players for $1750 or four televisions and one DVD players for $1250. Find the cost of one of each
Answer:
Television = $200 and DVD player = $450
Step-by-step explanation:
→ Make 2 equations
Televisions = t and DVD players = d
2t + 3d = 1750
4t + d = 1250
→ Multiply the bottom equation by 3 to make the same variable of d
2t + 3d = 1750
12t + 3d = 3750
→ Minus the two equations to isolate the d variable
-10t = -2000
→ Divide both sides by -10 to find the cost of one television
t = 200
→ Substitute t = 200 back into 4t + d = 1250
800 + d = 1250
→ Minus 800 from both sides to isolate d
d = 450

The Kraken is a mythical creature that was said to be known to consume ships whole. The great creature has long tentacles that are covered with suction cups. The kraken has a total of 8 tentacles and 1,000 suction cups total. The next number needed to open the treasure is the unit rate of suction cups per tentacle.
Answer:
The kraken has 125 suction cups on each tentacle.
Step-by-step explanation:
We know that the kraken has 8 tentacles, and a total of 1000 suction cups.
We can find the answer by dividing 1000 by 8 to find the unit rate of suction cups per tentacle.

Given PHS=CNF find the value of x, y and Z
Answer/Step-by-step explanation:
Since ∆PHS ≅ ∆CNF, therefore:
<P ≅ <C,
<H ≅ <N
<S ≅ <F
Thus:
Since, <P ≅ <C, therefore,
36° = (4z - 32)°
36 = 4z - 32
Add 32 to both sides
36 + 32 = 4z
68 = 4z
Divide both sides by 4
68/4 = z
17 = z
z = 17
Since <H ≅ <N, therefore:
6x - 29 = 115°
Add 29 to both sides
6x = 115 + 29
6x = 144
Divide both sides by 6
x = 114/6
x = 24
m<F + m<C + m<N = 180° (sum of ∆)
(3y - 1) + (4z - 32) + 115 = 180 (substitution)
Plug in the value of z and solve for y
3y - 1 + 4(17) - 32 + 115 = 180
3y - 1 + 68 - 32 + 115 = 180
3y + 150 = 180
Subtract 150 from both sides
3y = 180 - 150
3y = 30
y = 10
The value of x, y and z are 24, 10 and 17 respectively.
PHS≅CNF
Therefore,
∠P ≅ ∠C
∠H ≅ ∠N
∠S ≅ ∠F
36 = 4z - 32
36 + 32 = 4z
4z = 68
z = 68 / 4
z = 17
6x - 29 = 115
6x = 115 + 29
x = 144 / 6
x = 24
3y - 1 = 180 - 115 - (4z - 32)
3y - 1 = 180 - 115 - 4z + 32
3y - 1 = 97 - 4(17)
3y - 1 = 29
3y = 30
y = 30 / 3
y = 10

What is the slope of a line perpendicular to the line 2y = 3x - 10?
=================================================
Work Shown:
Solve the given equation for y
2y = 3x - 10
y = (3x-10)/2 ..... divide both sides by 2
y = (3x)/2 - 10/2
y = (3/2)x - 5
The equation is in y = mx+b form with m = 3/2 as the slope.
The perpendicular slope is -2/3 because we flip the fraction and the sign from positive to negative.
Note how multiplying the original slope 3/2 and the perpendicular slope -2/3 leads to -1
(3/2)*(-2/3) = -1
This is true for any pair of perpendicular lines, assuming neither line is vertical.
