Evaluate the expression 6 + 8f for f = 4.*​

Given :

Calculators cost $12.99 each, rulers cost $0.49 each, pencils cost $0.10 each, and erasers  cost $0.05 each.

To Find :

How much would Mrs. Algebra's single order be.

Solution :

Total price paid by Mrs. Algebra = Price of pencil + price of ruler + price of calculator + price of eraser.

T = $(0.10 + 0.49 + 12.99 + 0.05)

T = $13.63

Therefore, Mrs. Algebra's single order cost is $13.63 .

Hence, this is the required solution.

Answer:

-7

Step-by-step explanation:

Using the formula given above, just put in 4 and replace x. It will give you an answer of -7

Answer:

the shape is semetrical

Step-by-step explanation:

Answer: The facts Ab=Dc and Ac=Db are enough to show that Triangle ABC and Triangle DBC are congruent. This means that their similar angles will be equal like their sides.

Answer:

4x

Step-by-step explanation:

the -8 and +8 cancel out

x and 3x are both positive so add them

you're left with 4x

Simplifying is the same as solving this question. I'll give steps instead.

x - 8 + 3x + 8

x + 3x - 8 + 8       (Arrange the equation)

(x + 3x) (- 8 + 8)   (Parentheses the like terms together)

(4x) (0)                 (Solve)

4x                        (Simplified)

Answer:

a) (-2,-1)

b) (-3,0) (-1,0)

Step-by-step explanation:

It tells you on the graph

Answer:

a) I think the turning point is max or min correct? If so, the min of the function is (-2, -1) AKA the vertex

b) I also think the roots are just another way to say the x-intercepts so in that case, the roots are (-1, 0) and (-3, 0)

15% of 18 is 2.7 so 18 + 2.7 = 20.70

Answer:

she needs 5 times more of each item because

5(6)=30

Step-by-step explanation:

135 g(5)= 675 g flower

1tsp(5)= 5 tsp baking powder

2(5)= 10 tablespoons sugar

130(5)= 650 ml milk

1(5)= 5 eggs

2(5)= 10 tablespoons oil

Step-by-step explanation:

-3/10x=1/2+7

=15/2

x=15/2×10/-3=-25

-25<1/2

Difference between they both was

1/2-(-25)

1/2+(25)

=51/2

=25.5

Answer:

ok, tell me what you need, I will be glad to help!!

Step-by-step explanation:

Explanation:

We have x = 5 turn into x = 1. We need to subtract 4 from the x coordinate to get this. Therefore x turns into x-4.

The y coordinate stays at y = 2 the entire time, so y isn't altered. We have y map to y.

Overall, the rule is [tex](x,y) \to (x-4, y)[/tex] which translates the point 4 units to the left.

Answer:

The theoretical probability of obtaining letter 'r' at the 14th spin is:

1/8

Step-by-step explanation:

It is given that:

A spinner has 8 equal sectors with different letters for each sector.

The sectors are labeled b, y, g, p, o, v, m, and r.

Hamlet spins the spinner 13 times, and it stops at the letter r 9 times.

We are asked to find the theoretical probability that we will get  letter r at the 14th spin.

The theoretical Probability is given as the ratio of number of favorable outcomes to the total number of outcomes.

Hence, the theoretical probability of obtaining letter 'r' at the 14th spin is:

( As there are a total of 8 outcomes( or 8 sectors) out of which there is only one sector which is red)

Answer:

The two angles of ΔABC are equal to the two respective angles of ΔFED. Also, the sum of all interior angles of a triangle is 180º. Therefore, third angle of both triangles will also be equal in measure.

I took 5 1/3 and turned it into 16/3 and looked to see how many times 2 goes into 16 and got 8 so the answer is 8

Answer:

A $33.62

Step-by-step explanation:

To figure this out you have to take -92.80 and add 126.42 to get $33.62. Have a great day and LEAVE ME ALONE PLZ! <3

Answer:

-92.80+126.42=33.62

Step-by-step explanation

Since you owe $92.80 it would be a negative. So it would be like this.

126.42-92.80= 33.62

Or

-92.80+126.42=33.62

Hope this Helps.  

Answer:

[tex]\frac{-9}{12}[/tex]

Step-by-step explanation:

First, we need to isolate y.

1. Subtract 12x from both sides.

-9y=-12x+135

2. Divide by -9 in order to isolate y.

[tex]y=\frac{12}{9} x-15[/tex]

3. Understand that perpendicular equations' slopes are opposite and reciprocal to the original equation. The slope of the original equation is [tex]\frac{12}{9}[/tex], so the reciprocal and opposite (flip and change the sign) slope would be [tex]\frac{-9}{12}[/tex].
