Answer:

(3,3)

Step-by-step explanation:

you moved the point 2 units to the left. So the X value must go down 2.

(5-2,3)

Rate is ratio that compares two quantities of different units.

A rate is a special ratio in which the two terms are in different units. Rate can also be defined as the ratio between two quantities of different units

For example, velocity is an example of rate, because it defined by the ratio of distance covered and time.

The unit of distance is metres and the unit of time is second. Therefore ;

velocity = distance /time. Therefore velocity is a rate.

Another example is ; Ade eat 5 mangoes for 20 days. The rate at which Ade eat is

1 day = 5/20

= 1/4 mangoes. This means Ade eats 1/4 mangoes per day.

Step-by-step explanation:

Answer:

BC ≈ 19.4 cm

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos71° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{AB}{BC}[/tex] = [tex]\frac{6.3}{BC}[/tex] ( multiply both sides by BC )

BC × cos71° = 6.3 ( divide both sides by cos71° )

BC = [tex]\frac{6.3}{cos71}[/tex] ≈ 19.4 cm ( to 3 significant figures )

Step-by-step explanation:

The years needed to make $3000 to $5000 is 12.5.

Compound interest simply means that the interest associated with a bank account, loan, or investment increases exponentially over time.

Given that, an investment of $3000 to amount to 5,000 if money is invested at 4.1% compounded monthly

A = P(1+r/12)^12t

5000 = 3000(1+0.041/12)^12t

5/3 = (1.0034)^12t

Taking log both sides,

log5/3 = 12tlog(1.0034)

0.221 = 12t0.00147

12t = 150.34

t = 12.5

Hence, required years are 12.5.

Answer:

The total number of burritos consumed is 68 and an equation to determine the total number of burritos consumed is [tex]\frac{1}{2}x+16=\frac{3}{4}x-1[/tex]

Step-by-step explanation:

Let x be the total number of burritos consumed

We are given that On Tuesday, Delainey ate 16 more than 1/2 the total number of burritos consumed

So, Number of burritos ate by Delainey on Tuesday=[tex]\frac{1}{2}x+16[/tex]

We are also given that  Louie ate 1 less than 3/4 of the total number of burritos consumed.

So, Number of burritos ate by Louie on Wednesday =[tex]\frac{3}{4}x-1[/tex]

We are given that The number of burritos Delainy ate on Tuesday is the same as the number of burritos Louie ate on Wednesday.

So, [tex]\frac{1}{2}x+16=\frac{3}{4}x-1\\1+16=\frac{3}{4}x-\frac{1}{2}x\\17=\frac{x}{4}\\68=x[/tex]

Hence  the total number of burritos consumed is 68 and an equation to determine the total number of burritos consumed is [tex]\frac{1}{2}x+16=\frac{3}{4}x-1[/tex]

-7/4

Step-by-step explanation:

The slope of the line is -7/4

Answer:

= -7/4

Step-by-step explanation:

When we have 2 points, we can use the slope formula

m = ( y2-y1)/(x2-x1)

   = ( -14-7)/(9- -3)

   = ( -14-7)/(9+3)

   = -21/12

Step-by-step explanation:

Answer:

14. d

15. b

Step-by-step explanation:

steps for #14:

1. complementary angles are angles that equal 90 degrees when added together. so, those two angles equal 90. make an equation to represent this.

  (x + 5) + (x - 9) = 90

2. combine like terms.

  2x - 4 = 90

3. solve for x.

  2x = 94

     x = 47

4. plug x into both formulas to find the measurements of each angle.

  47 + 5    AND     47 - 9  

     d. angle DFG = 52, angle JKL = 38

steps for #15:

1. when angles are linear pairs, it means they equal 180 degrees when added together. so, these two angles equal 180. make an equation to represent this.

  (x - 39) + (x + 61) = 180

2. combine like terms.

  2x + 22 = 180

3. solve for x.

  2x = 158

     x = 79

4. plug x into both formulas to find the measurements of each angle.

  79 - 39    AND      79 + 61

     b. angle 1 = 40, angle 2 = 140
