Answer:
∀s ∈ D, C(s) - - - > E(s)
∀s ∈ D, C(s) - - - > ~ E(s)
∃s ∈ D such that M(s) ∧ C(s)
Step-by-step explanation:
D = set of all students
M(s) = s math major
C(s) = s Computer science major
E(s) = s Engineering major
Expressing the following using quantifies variables and predicates :
A.) Every computer science student is an engineering student
∀s ∈ D, C(s) - - - > E(s)
b. No computer science students are engineering students
∀s ∈ D, C(s) - - - > ~ E(s)
c. Some computer science students are also math majors
∃s ∈ D such that M(s) ∧ C(s)
∃s = Existential Domain
∀s = universal
∧ = connective and
~ = not
∈ = belongs to
A student is solving the problem X to the power of 2+10x+ __=16+ __ my method of completing the square. What number should the student add to both sides?
A) 4
B)5
C) 25
D) 16
Answer: C) 25
Step-by-step explanation:
x²+10x+ __=16+ __
Only the square of 5, 5², which is 25, can make the two factors plus equal to 10x, so we need to add 25.
How many solutions does this system have?
->
2x-3y = 10
-4x+6y=-20
one
two
an infinite number
no solution
Answer: I think there is only one
Step-by-step explanation:
Answer:
an infinite number
Step-by-step explanation:
Let's solve for y for both equations.
[tex]2x-3y=10\\-3y=10-2x\\y=\frac{2}{3}x-\frac{10}{3}[/tex]
[tex]-4x+6y=-20\\6y=4x-20\\y=\frac{4}{6} x-\frac{20}{6}[/tex]
By reducing fractions we get:
[tex]y=\frac{2}{3}x- \frac{10}{3}[/tex]
These two equations are EXACTLY the same.
Therefore, this system has an infinite number amount of solutions.
Using desmos graphing calculator, you can't see both lines because they're exactly the same line.

Juhi sells a washing machine for Rs 13500. She loses 20% in the bargain . What was the price at which she bought it
➽ Let the cost price of the washing machine be a variable and apply the condition that the loss Juhi faced was 20% of the cost price, i.e., Rs. 13,500 is 80% of the cost price to form an equation. Solve the equation to get the answer.
Solution :➽ The selling price of the washing machine after bargain = Rs 13, 500
➽ percentage of loss she had in the bargain = 20 %
let the price paid by juhi be x
➽ Now interpreting the statement in the question
in mathematical form we get :
[tex] \implies[/tex] loss = Rs 2 / 10 × 2
[tex] \implies[/tex] Loss = Rs 2 / 10 × x
➽ According to the simple marketing norm, if we subtract the loss from the buying price, we will be getting the selling price for which Juhi sold the washing machine.
Profit / loss = purchasing price - Selling price
Substituting the values the above equation, we get;
[tex] \implies[/tex] 2 x / 10 = x - 13500
[tex] \implies[/tex] 2 x / 10 = x - 13500 / 2
On cross-multiplication, we get;
2 x = 10 ( x - 13500 )
[tex] \implies[/tex] 2 x = 10 x - 13500
[tex] \implies[/tex] 8 x = 13500
∴ x = 13500 / 8 = 16875
∴ Hence the price that Juhi paid for buying the Washing machine was Rs. 16,875.Additional information :
❑ Don’t get confused and take the 20% of the selling price while you solve, as you should be very clear that the percentage loss or profit are terms related to the actual pricing not to the price for which you crack the deal. The other way of thinking of this is that the selling price might vary from buyer to buyer depending on the bargain they put in, but the percentage should be defined from a fixed mark so that you can easily handle it. The reason that most products in the market have an MRP tag on it making it easier for all the sellers to handle their margins.

Write the equation of a quadratic function who has the vertex of (4,-7)
Given:
The vertex of a quadratic function is (4,-7).
To find:
The equation of the quadratic function.
Solution:
The vertex form of a quadratic function is:
[tex]y=a(x-h)^2+k[/tex] ...(i)
Where a is a constant and (h,k) is vertex.
The vertex is at point (4,-7).
Putting h=4 and k=-7 in (i), we get
[tex]y=a(x-4)^2+(-7)[/tex]
[tex]y=a(x-4)^2-7[/tex]
The required equation of the quadratic function is [tex]y=a(x-4)^2-7[/tex] where, a is a constant.
Putting a=1, we get
[tex]y=(1)(x-4)^2-7[/tex]
[tex]y=(x^2-8x+16)-7[/tex] [tex][\because (a-b)^2=a^2-2ab+b^2][/tex]
[tex]y=x^2-8x+9[/tex]
Therefore, the required quadratic function is [tex]y=x^2-8x+9[/tex].

PROCESSING BASE ANGLES
OF AN ISOSCELES TRIANGLE
Answer:
m<A = 69°
m<C = 69°
Step-by-step explanation:
From the question given above, the following data were obtained:
AB = AC
m<B = 42°
m<A =?
m<C =?
Since:
AB = AC
Therefore,
m<A = m<C
A + B + C = 180 (sum of angles in a triangle)
C + 42 + C = 180
Collect like terms
C + C = 180 – 42
2C = 138
Divide both side by 2
C = 138 / 2
C = 69°
Finally, we shall determine m<A. This can be obtained as follow:
m<A = m<C
m<C = 69°
Therefore,
m<A = 69°
Can someone please help meeeee
Answer:
45°
Step-by-step explanation:
The angle with measure of 9x and the angle with measure of 3x are supplementary
9x + 3x = 180°
12x = 180 divide both sides by 12
x = 15
The angle with measure of 9x and angle a are supplementary as well
9x + a = 180
9×15 + a = 180
135 + a = 180 subtract 135 ftom both sides
a = 45°
x-8= -12 what is x in the equation
Answer:
-4
Step-by-step explanation:
Answer:
x = -4
Step-by-step explanation:
Isolate the variable x
x - 8 = -12
To isolate the variable, add 8 to both sides (this cancels the 8 out on the left side)
x - 8 + 8 = -12 + 8
x + 0 = -4
x = -4

If a translation maps zl onto ZK, which of the following statements is true? G HS 1 K НІ is twice the measure of 2JK: GH is twice the measure of 2GJ: Triangles AGHI and AGJK are not similar. OCH = J
9514 1404 393
Answer:
(d) ∠H ≅ ∠J
Step-by-step explanation:
We already know that ∠G is congruent to itself. If we show (by translation or other means) that ∠I ≅ ∠K, then we know that ΔGHI ~ ΔGJK. The third angle in each triangle will be congruent, too.
∠H ≅ ∠J
_____
The problem is concerned with angles, so the first two answer choices are irrelevant. If two angles are shown congruent, the triangles are congruent by AA similarity, so the third answer choice is incorrect.

Answer: 1 is D and 2 is B I think
Step-by-step explanation: 1 is D because 59.2 + (-84.7) because D is the same thing as 59.2-84.7, just written differently. 2 is B because the longer line resembles -15 and the smaller line resembles 6. -9 is circled because its supposed to add up to -9, hence why it would be 6+(-15)=-9.
