Find e and d

3e+d=8

2e+d=8

**Answer:**

**Step-by-step explanation:**

3e+d=8

2e+d=8

Multiply the second equation by -1

You get

-3e-d=-8

Use eliminating methods

-3e-d=-8

2e+d=8

We get

-e=0

So e=0

Find e by substitute it in one of the equation

2*0+d=8

D

d=8

2e+d=8

Multiply the second equation by -1

You get

-3e-d=-8

Use eliminating methods

explain how 984/616=123/77

They are equal because you can multiply the numerator and denominator of 123/77 by 8

And you get

984/616

Hope this helps!

Brainliest is much appreciated!

And you get

984/616

Hope this helps!

Brainliest is much appreciated!

**Answer:**

984/616 is equal to 123/77 because it is simplified, also meaning reduced by finding the GCF (greatest common factor), which in this case is 8. So therefore, when you divide the numerator of 984 by 8, you get 123, and when you divide the denominator of 616 by 8 as well, you will get 77.

Line c passes through points (9, 10) and (1, 3). Line d is perpendicular to c. What is the slope

of line d?

**Answer:**

-8/7

**Step-by-step explanation:**

First, find the slope of line c.

(x1, y1) = (9, 10)

(x2, y2) = (1, 3)

The slope formula is:

[tex]m=\frac{y2-y1}{x2-x1}[/tex]

Solve for the slope using the given values:

[tex]m=\frac{3-10}{1-9}\\\\m=\frac{-7}{-8}\\\\m=\frac{7}{8}[/tex]

The slope of line c is 7/8. To find the slope perpendicular to it, you need to find the negative reciprocal of that number. An example of that would be 2 and -1/2. Basically, flip the fraction and the +/-.

In this case, the negative reciprocal of 7/8 is -8/7. The image below doesn't account for the y-intercept, but it does show that the slopes are perpendicular.

**Answer:**

slope = - [tex]\frac{8}{7}[/tex]

**Step-by-step explanation:**

Calculate the slope m of line c using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (9, 10 ) and (x₂, y₂ ) = (1, 3 )

m = [tex]\frac{3-10}{1-9}[/tex] = [tex]\frac{-7}{-8}[/tex] = [tex]\frac{7}{8}[/tex]

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{7}{8} }[/tex] = - [tex]\frac{8}{7}[/tex] ← slope of line d

Marta bought c CDs for $ 12 each, b books for $ 7 each, and a bag for $ 24 to.

Write an expression to show the total money Marta spent.

If Marta bought 4 CDs and 3 books, how much did she spend?

**Answer:**

A, 12c + 7b + 24

B, $69

**Step-by-step explanation:**

Please, read my picture Thanks! Also tell me if its right in the comment

4 * 12 + 3 * 7 + 24 = m

m represents how much money Marta spent

48 + 21 + 24 = m

69 + 24 = m

$93 = m

The amount of money Juan makes from selling x books is represented by the equation y=15x

What is the theoretical range of the equation?

Question 2 options:

All multiples of 20 between 0 and 300, inclusive

All integers from 0 to 20, inclusive

All multiples of 15 between 0 and 300, inclusive

All real numbers

**Answer:**

Well u would multiply 20 x 15 to find out the highest if the range which is 300 . So that knocks it down to B or D. But since they're $15 each, It would be based of the multiples of 15 making your answer B .

The range is all the y values.....or the f(x) values .

So the practical range would be the multiples of 15 between 0 and 300,Inclusive .

Hope this helps you!!Find the domain of the expression.

the square root of x+5

See attachment for answer and math work.

Answer:

Step-by-step explanation:

"Domain" means what numbers are allowed to be x (or on a graph, for what x's does the graph exist)

Since inside a square root you have to have a positive number (actually, just not a negative number). So all the positive numbers work (any positive+5 is a positive number) BUT ALSO x can be 0, BUT ALSO, x can be as small as -5 and still the value inside the square root will not be negative

SO THIS MEANS all the x's we're allowed to use (that's the DOMAIN) are everything from -5 and bigger. In math we write that as x>= -5

There are two other main ways to write it: [-5, infinity symbol) OR {x|x>=-5} these all mean the same thing.

Mitchell buys a $1,400 dryer with an installment plan that requires 17% down. How much is the down payment?

The amount of **down payment** Michelle paid for a dryer of **$1,400** at **17%** down payment is **$238**

Given:

Total cost of dryer = **$1,400**

down payment percentage = **17%**

*Amount paid for down payment* = **17% of $1,400**

= 17/100 × 1400

= 0.17 × 1400

= $**238**

Therefore, the **amount** of **down payment** Michelle paid for a dryer of **$1,400** at **17%** down payment is **$238**

Jane drew a scale drawing of a city park. She used the scale 3 centimeters : 4 meters. The soccer field is 108 meters long in real life. How long is the field in the drawing?

If you do 108/4 you get 27 so then you do 27x3 which should get you the real centimeter

The **length **of the field in the drawing is 81 cm

**What is Proportion?**

The **proportion **formula is used to depict if two ratios or fractions are equal. The **proportion **formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.

Given data ,

**Scale **of the drawing : **Length **in meters is in the ration 3 cm : 4 m

**Length **of the soccer field is 108 m

Now , **length **of 108 m soccer field in **scale **of drawing = x

From **proportion formula** , we can deduce that

3 : 4 : : x : 108

So ,

3/4 = x/108

**Multiply **by 108 on both sides , we get

( 3 x 108 ) / 4 = x

x = 3 x 27 cm

x = 81 cm

Hence , **length **of the field in the drawing is 81 cm
