HELP!! Which pair of statements is true

vitfil [10]

Answer:

B

Step-by-step explanation:

If A = {1, 2, 3} and B = {1, 2, 3, 4, 5}

We say that A is a subset of B, since every element of A is also in B.

So

If set A is all odd numbers then R belongs to A bcz all the elements of R are odd numbers

11r+7s help me please

Maru [420]

Answer: First term = 11r and second term= 7s

The coefficient in first term = 11

The coefficient in second term =7

Step-by-step explanation:

The given expression 11r + 7s is with two terms i.e. a binomial expression with variables r and s

Here the first term = 11r

And the coefficient of r in term =11

The second term= 7s

The coefficient of s in second term=7

The coefficients are the numbers that multiply the variables .

jermey wants to buy a new computer . the saleswomen says he can make a down payment and then pay for the computer in installment

hodyreva [135]

Answer:

The correct answer is:

$y=\frac{-x+t}{z} \\$

Step-by-step explanation:

We want to solve for the amount of money he pays each month. This is represented by y in the equation. This means we want to isolate y in the equation:

x = t - yz

We first want to subtract t from each side:

x - t = t - yz - t

x - t = -yz

Now we want to cancel the negative sign and z. We can isolate both of these at the same time; divide both sides by -z:

\frac{x-t}{-z} = \frac{-yz}{-z} \\ \\\frac{x-t}{-z}=y

We can divide the numerator by the negative sign; this gives us

\frac{-x+t}{z}=y

Pls pls pls help if ur good with angles and sides

Answer:

∆PQR: Equilateral Triangle

∆PRT: Scalene Triangle

∆TQS: Isosceles Triangle

∆QNP: Right Triangle

Step-by-step explanation:

∆PQR is an Equilateral Triangle because all of its angles are equal (60°).

∆PRT is a Scalene Triangle because none of its sides are equal.

The triangle above it is equilateral, and one side length is 14, meaning all of its side lengths are 14.

This makes the top of ∆PRT 14. The hypotenuse is given and it’s 18.

The last side left is clearly shorter than both, meaning none of the sides are equal.

∆TQS is an Isosceles Triangle because 2 angles are equal.

The base angles are both 76°.

∆QNP is a Right Triangle because segment QN and PR are perpendicular, creating two 90° angles on both sides.

For number 10, I suggest using a graphing calculator or desmos to graph the points. (Or you can just add the points but I suggest graphing).

From there, you can count the length of each side.

Segment DE: 9

Segment EF: 8

Segment FD: 10

This makes ∆DEF in number 10 a Scalene Triangle because none of its sides are equal.

For number 11, I also suggest graphing the points and counting the sides.

Segment DE: 7

Segment EF: 9

Segment FD: 7

This makes ∆DEF in number 11 an Isosceles Triangle because 2 of its sides are equal.

Hope this helps! :)
