At an average rate of $3 per day, in 14 days Brian will have spent ...

  ($3/day)(14 days) = $42

If he has $68 left, then he must have started with ...

  $68 +42 = $110

Explanation:

Choice A is a reflection. Choice C is a rotation. Reflections and rotations are isometries because they preserve the same shape and size of the original figure. Translations are the third type of isometry.

Choice B is not an isometry. It looks like an extra point is added along with extra line segments. The before and after figures are completely different.

Answer:

4 Tacos

Step-by-step explanation:

It cost less for four tacos then five tacos

Answer: 4 tacos for 3.20

Step-by-step explanation: if you divide 3.20 by 4 it equals 0.80 cents for each taco and 4.25 divided by 5 equals 0.85 cents for each taco.

Answer:

41 Fahrenheit

Step-by-step explanation:

The convertion formula is:

(C × 9/5) + 32 = F

So if we fill in the blanks we get:

(5°C × 9/5) + 32 = 41°F

So the anwser is 41°F

Answer:

Step-by-step explanation:

since the first equation is already simplifies to y = 2x plug in 2x for the y in the second equation and solve

x = -(2x) + 6

x = -2x + 6

3x = 6

x = 2

plug in our x to the original equation

y = 2(2)

y = 4

so our answer is (2,4)

hope this helps <3

Answer:

x = 2

Step-by-step explanation:

If y is 2x, and x is -y + 6, what's x?

So let's use substitution method. Just replace the -y in x = -y + 6 with 2x:

x = -y + 6

x = -2x + 6

add 2x to both sides

3x = 6

divide by 3

x = 2

Answer:

56

Step-by-step explanation:

When we divide a number with a fraction, we change the sign into a multiplication sign, and we do the reciprocal.  Then we multiply across.

Answer:

1/52

Step-by-step explanation:

To obtain the probability of drawing a 9 of spade from a deck of 52 cards ;

Probability = (number of required outcomes / number of total possible outcomes)

Number of Required outcomes = 1 (there is only one 9 of spade in a deck of 52 cards)

Hence,

P(9 of spade). = 1 / 52

Answer:

-1/4

Answer:

the third one should be it

Answer:

Please check the explanation.

Step-by-step explanation:

1)

From the graph, taking the two points

(3, -5)

(-3, 5)

The slope between (3, -5) and (-3, 5) will be:

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m=\frac{5-\left(-5\right)}{-3-3}[/tex]

[tex]m=-\frac{5}{3}[/tex]

Therefore, the slope is:

[tex]m=-\frac{5}{3}[/tex]

2)

1ST METHOD

We know that the y-intercept of the graph of the linear function can be determined by setting x=0 and solving for y

From the graph, it is clear that:

at x=0, y=0

Thus, the y-intercept is: (0, 0)

2ND METHOD

We know that the slope-intercept form of the line equation is

[tex]y=mx+b[/tex]

where 'm' is the slope and 'b' is the y-intercept

substituting the point (3, -5) and m=-5/3 in the slope-intercept form

[tex]y=mx+b[/tex]

[tex]-5=\frac{-5}{3}\left(3\right)+b[/tex]

[tex]\frac{-5}{3}\left(3\right)+b=-5[/tex]

[tex]-5+b=-5[/tex]

[tex]b=0[/tex]

Thus, the y-intercept is: (0, 0)

3)

We know that the slope-intercept form of the line equation is

[tex]y=mx+b[/tex]

substituting m=-5/3 and b=0 to determine the equation line in the slope-intercept form

[tex]y=\frac{-5}{3}x+0[/tex]

Therefore, the equation line in the slope-intercept form is:

[tex]y=\frac{-5}{3}x+0[/tex]

where m=-5/3 and b=0

Step-by-step explanation:

From the options provided the only one that represents a proportional relationship was The cost of purchasing a box of socks for $1.75 per sock plus $2.15 for the box. This is because the total cost of the boxes depends on the number of socks that are bought since every pair of socks that are bought comes with a box which causes the total costs of the boxes to increase. Therefore, the number of sock pairs and the number of boxes has a proportional relationship.

Answer:

The gas pump filling the gallons in 1 minute will be: 15

Step-by-step explanation:

As there are 60 seconds in 1 minute.

Thus,

Gas pump filling the gallons in 1 minute will be:

[tex]60\:\times 2^{-2}[/tex]

[tex]=60\times \frac{1}{2^2}[/tex]             ∵ [tex]a^{-b}=\frac{1}{a^b}[/tex]

[tex]\mathrm{Multiply\:fractions}:\quad \:a\times \frac{b}{c}=\frac{a\:\times \:b}{c}[/tex]

[tex]=\frac{1\times \:60}{2^2}[/tex]

[tex]=\frac{60}{2^2}[/tex]

[tex]=\frac{2^2\times \:3\times \:5}{2^2}[/tex]

[tex]=3\times \:5[/tex]

[tex]=15[/tex] gallons in one minute

Therefore, the gas pump filling the gallons in 1 minute will be: 15
