Answer:

Option 3 y=ex-3 hoping this helps

Answer:

Step-by-step explanation:

4y = 20 + 8x

y = 5 + 2x

Answer:

Option B

Step-by-step explanation:

-8x + 4y = 20

[tex]-8x+8x+4y=20+8x \leftarrow \text {Addition Property of Equality.}\\4y=20+8x\\\\\frac{4y}{4}=\frac{20+8x}{4} \leftarrow \text {Division Property of Equality.}\\y=5+2x\\\boxed {y=2x+5}[/tex]

Option B should be the correct answer.

Answer:

y=-3/2x-.5

Step-by-step explanation:

(5,-4) and (1,-2)

Step 1: find slope:

-4-2/5-1=-6/4=-3/2

y=mx+b

y=-3/2x+b

2.: Plug in point

(1,-2)

-2=-3/2*1+b

-2=-3/2+b

-2+3/2=b

b=-.5

Answer: 9

Step-by-step explanation: 2 negative numbers become a positive number when multiplied or divided..... so when we multiply both of these negative numbers (or just do 2 times 4.5) your answer will be 9

The value of JW is 14 units.

A triangle is a polygon with 3 sides. The area of a triangle with base b and height h is given by A = (1/2)bh.

Given that, JB is the median of the triangle and JW = 6x + 2 and JB = 10x + 1.

The distance between the centroid and a vertex of a triangle is 2/3 of the length of the median, therefore, it follows:

JW = (2/3)JB

Substitute the values:

6x + 2 = (2/3)(10x + 1)

18x + 6 = 20x + 2

2x = 4

x = 2

Substitute x = 2 into the expression for JW:

JW = 6(2) + 2

JW = 14

Hence, the value of JW is 14 units.

Answer: 140%

Step-by-step explanation:

STEP 1: FIND THE CHANGE IN # OF PEOPLE:

initial # of people: 144

final # of people: 346

change in # of people = (final - initial)

change in # of people = (346 - 144)

change in # of people = 202

STEP 2: FIND THE % CHANGE

202/144 = x/100

(100)(202/144) = x

100(1.4) = x

140% = x

Answer:

140 %

Step-by-step explanation:

(346-144)/144 * 100

(202/144) * 100

x = 7

Step-by-step explanation:

The two triangles are similar by AA similarity.

6 : 36 = x : 42

1 : 6 = x : 42

x = 7

Answer:

Answer would be 7.

Step-by-step explanation:

Answer:

x > 0

Step-by-step explanation:

Division by zero is not defined.  Therefore, x must be greater than zero.  Also:  The square root function is defined only for x greater than zero or equal to zero.  Together these restrictions tell us that the domain is (0, infinity ).

Answer: x = 2

Step-by-step explanation: To solve this equation, we start by distributing the 4 through the parentheses on the left side.

So we have 4(x) which is 4x and 4(6) which is 24.

So our equation now reads 4x + 24 = 32.

Solving from here, we subtract 24 from both sides to get 4x = 8.

Then divide both sides by 4 to get x = 2.

Answer:

Correct option: second one -> 24 square units

Step-by-step explanation:

First we need to find the length of each side of the trapezoid, and we do that finding the distance between points:

AB = sqrt( (-1 - (-3))^2 + (2 - (-2))^2) = 4.4721

BC = sqrt( (3 - (-1))^2 + (2 - 2)^2) = 4

CD = sqrt( (5 - 3)^2 + (-2 - 2)^2) = 4.4721

DA = sqrt( (-3 - 5)^2 + (-2 - (-2))^2) = 8

The points B and C have the same y-coordinate, and the points D and A also have the same y-coordinate, so they are the bases of the trapezoid.

The height of the trapezoid is the difference in y-coordinate of points B and A:

height = 2 - (-2) = 4

So the area of the trapezoid is:

Area = (BC + DA) * 4 / 2 = (4 + 8) * 2 = 24 square units

Correct option: second one

Answer:

Its B

Answer:

see below

Step-by-step explanation:

Starting with 50

Took out 20

50-20 = 30

Then the balance was 0

We need to subtract 30 to get to get to 0

30-30 = 0

Taking out 30

Withdrawing 30

Spending 30

All are ways of indicating taking out 30 dollars

Answer:

On Tuesday, Devon took 30 dollars out of his checking account.

Step-by-step explanation:

Starting with: $50        -        Ending with $0

Monday: took out $20 or in other words -20   50-20=30

Tuesday: undetermined, but since that was his last day, it would correspond with $0 so, he must've took out $30 and then ended up with none in the end.

30-30=0

So, he took 30 dollars out on tuesday.

Answer:

g(n) = [tex]\frac{11+5n}{3}[/tex]

Step-by-step explanation:

Given

3m - 5n = 11

Rearrange making m the subject

Add 5n to both sides

3m = 11 + 5n ( divide both sides by 3 )

m = [tex]\frac{11+5n}{3}[/tex] , thus

m = g(n) = [tex]\frac{11+5n}{3}[/tex]

Answer:

No, this triangle is not a right triangle

Step-by-step explanation:

If (7 cm)^2 + (15 cm)^2 = (16 cm)^2, then this is a right triangle, by the Pythagorean Theorem.  Otherwise it is not.

15^2 + 7^2 = 225 + 49 = 1225 = 35^2.  This is FALSE, and so:

No, this triangle is not a right triangle

Answer:

254.34 cm^2

Step-by-step explanation:

Volume of cylinder = [tex]\pi r^{2} h[/tex]

We know that the diameter is 6, which means that the radius is 3 cm.

Now, it also tell us that that the height is triple the radius, this means that we multiply it by 3. Therefore, the height is 9 cm.

Now we know r = 3 cm and h = 9 cm, pi is assumed to 3.14 as well.

Substituting into the formula we will end up with 254.34 cm^2.
