Answer:

3z+2= x ; z=5

3(5)+2

15+2

17

Step-by-step explanation:

The value of the given expression at z = 5 is 45.

An algebraic expression can be obtained by doing mathematical operations on the variable and constant terms.

The variable part of an algebraic expression can never be added or subtracted from the constant part.

The given algebraic expression is 3z²− 6z.

The value of the expression at z = 5 is given as follows,

3z²− 6z

Substitute z = 5 to obtain,

3 × 5²− 6 × 5

= 75 - 30

= 45

Hence, the given expression can be simplified as 45.

Answer:

x = 48°

Step-by-step explanation:

In the given triangle XYZ,

Sides XY and XZ are congruent.

Therefore, both the sides will be equal in measure.

By the definition of isosceles triangle,

"Opposite angles of the equal sides are equal in measure"

m∠Y = m∠Z = x°

m∠X = 84° [Given]

By the triangle sum theorem,

m∠X + m∠Y + m∠Z = 180°

84° + x° + x° = 180°

2x = 180 - 84

x = 48°

Therefore, measure of x = 48° will be the answer.

BUNNY: y = 3x + 5

CAT: y = 1x + 19

Step-by-step explanation:

Answer:

Bunny: 5 + 3y

Cat: 19 + y

Step-by-step explanation:

If we were trying to make an equation about the total number of pounds each animal weighs, we would take the current number of pounds for each animal and then add the product of the pounds they gain and the number of years.

Bunny: 5 + 3y

y - number of years

5 current pounds  + 3 additional pounds * y

Cat: 19 + y

y -  number of years

19 current pounds + 1 additional pound per year or just 'y'

Answer:

C or A

Step-by-step explanation:

Answer:

I would go with A

Step-by-step explanation:

A - Starts at (0, 0)

A - Ends at (8, 5)

B - Starts at (0, 0)

B - Ends at (3, 7)

A - X = 8 Y = 5

B - X = 3 Y = 7

The difference

A went 5 more then B did when comparing X, however, B's Y-Axis went further then A's Y-Axis

Answer:

If there are 1000 customers in the store one week, how many will purchase exactly one of these items

1000 CUSTOMERS*28%=280

Step-by-step explanation:

A The event that a persons buys a suit  

B The event that a person buys a shirt  

C The event that a person buys a tie  

P(A)=  22%

P(B)=  30%

P(C)=  28%

P(AB)= 11%

P(AC)= 14%

P(BC)= 10%

P(ABC)= 6%

A u B u C Is the event that any item is bougth

AC u AC u BC Is the event that any two events occured

So the wanted probability is

P[(A u B u C )(AB u AC u BC)^c

P[(A u B u C )=P(AB)+ P(BC)+P(BC)

P[(A u B u C ) =0.22+0.30+0.28-0.11-0.14.-0.10+0.06

                      =0,51

0,51=+0,23+P[(A u B u C )(AB u AC u BC)^c

        =0,28

1000 CUSTOMERS*28%=280

Answer:

y-intercept is 5

Step-by-step explanation:

Slope-Intercept Form: y = mx + b

m = slope

b = y-intercept

The equation of the line you gave is in slope-intercept form.

y = 3x + 5

3 is the slope, and 5 is the y-intercept.

Answer:

C

Step-by-step explanation:

The x coordinate of the rest stop:

1/2 × (the sum of the x coordinates of the highschool and the stadium)

= 1/2 × (3+7)

= 1/2 × 10

= 5

The y coordinate of the rest stop:

- Same thing i did for the x coordinate, but use the y coordinates.

1/2 × (the sum of the y coordinates of the highschool and the stadium)

= 1/2 × (4 + 1)

= 1/2 × 5

=5/2

So the coordinate of the rest stop would be (5, 5/2).

Next for the distance, i used the pythagoras theory so it's like this:

a^2 + b^2 = c^2

Here you plot the highschool and the stadium on the coodinate plane, then connect the two dots to make a right triangle. The height of the triangle will be 3, and the base would be 4. So a=3, b=4 in the equation.

3^2 + 4^2 = c^2

9 + 16 + c^2

25 + c^2

c = 5

(Note that this isn't the real answer cuz at the end of the question it said that one UNIT equals 6.4 MILES.)

So the final answer is 5 × 6.4, which is 32. The answer is C.

Answer:

Because the total is 49.77 and the total is the bill + tip, then the tip is 49.77 - 42 or $7.77. To find the percentage, we just calculate 7.77/42 as a percentage to get 1.11/6 = (111/6)% or 37/2 percent or 18.5%

Answer:

Means to write a product with A as a factor B times

Step-by-step explanation:

In general when b is a positive integer aᵇ means to write a product with a as a factor b times.

We know that,

aᵇ = a * a * a * a......

The number of a is b

So, aᵇ means to write a product with a as a factor b times.

Answer:

The missing angle is about 27.92°.

Step-by-step explanation:

This is a tangent equation, as there is no hypotenuse value. I'll use x as the missing angle.

tan(x) = opposite/adjacent

tan(x) = 20/38

tan(x) = 0.52631578947368421052631578947368

tan(x) ≈ 0.53

Now, we have to reverse.

tan⁻¹(0.53) = x

27.92358972 = x

x ≈ 27.92°
