Answer:

y = x - 3

Step-by-step explanation:

Answer:

Y= x-3

Step-by-step explanation:

The distance from our y values is -1.

The distance from our x values is -1.

Rise/ Run = Y/X

-1/-1 = 1 or 1/1

You would rise 1 and run 1!

You can use this strategy if you're using graph paper to eventually get the y intercept which is -3.

Figure ABCD is a parallelogram. Is triangle ADB congruent to triangle CBD? Show or explain your reasoning​

Answers

Answer:

yes it's congruent.

Step-by-step explanation:

in a parellelogram, all sides and angles are equal.

ΔADB is congruent to ΔCBD.

The reasoning is given below.

What is a parallelogram?

A parallelogram is a quadrilateral that has two pairs of parallel sides.

In a parallelogram, opposite sides and angles are equal.

The adjacent angles add up to 180 degrees.

We have,

A parallelogram ABCD.

This means,

AD is parallel to BC

AB is parallel to CD

∠A = ∠C

BD is the diagonal of the parallelogram.

Now,

ΔADB and ΔCBD

AB = CD ( given )

∠A = ∠C (given )

∠ADB = ∠CBD ( given )

∠ABD = ∠BDC ( alternate angles )

ΔADB ≈ ΔCBD

Thus,

ΔADB is congruent to ΔCBD.

Kelsey wants to buy some new shirts at her favorite store. Each shirt costs $10 and she also wants to get a pair of shoes for $25.write an inequality. That she could use to figure out how many shirts she can buy if the most she can spend is $55 and solve

Answers

Answer:

10x + 25 less than or equal to (the sign) $55

Step-by-step explanation:

Answer:

The inequality is 10x + 25 [tex]\geq[/tex] 55

Step-by-step explanation:

This would be the possible inequality, because it says that "EACH" shirt costs 10$ meaning that Kelsey may buy multiple, which is why you would want to put 10x (for every shirt she buys they each cost 10 dollars) and PLUS she wants a pair of sneakers, so add 25 $

She has only 55$ to spend, so here MAXIMUM amount she can spend is 55$ which means, she can only buy whatever she wants for 55$ or lower.

Dhruv jogs 8 feet per second.

I don’t know the answer please help.

Answers

The answer is 5.5 mph

The question requires changing feet per second into miles per hour

The unit rate in miles per hour is 5.5 miles per hour

8 feet = 0.00151515 miles

1 second = 0.000277778 hour

unit rate in miles per hour = number of miles / number of hours

= 0.00151515 mile / 0.000277778 hour

= 5.4545356363714 miles per hour

One gram of protein contains 4 calories. One gram of fat contains 9 calories. A snack has 80 calories from x grams of protein and y grams of fat. 80= 4x + 9y

If there are 6 grams of fat in the snack, how many grams of protein are there? Show your reasoning.

Answers

Answer:

6,5g of protein

Step-by-step explanation:

80=4x + 9y

y=6 ( "6 grams of fat")

so: 80=4x+9.6

80-54= 4x

26/4=x

x(protein)= 6,5

Answer:

  6.5 grams

Step-by-step explanation:

To find the value of x that corresponds to the given value of y, put that y-value into the equation and solve for x.

  80 = 4x +9·6

  26 = 4x

  26/4 = x = 6.5

There are 6.5 grams of protein in the snack.

What is the position of C on the number line below?

Answers

Answer:

2/5

Step-by-step explanation:

there are 5 lines starting at point 1 and ending at 2. point c is on the second line which makes it 2/5ths

The position of C on the number line below is 7/5 or 1 2/5.

What is the number line?

The number line is a horizontal line where all the integers are placed at equal intervals. The number line is extended to infinity on both sides.

Also, the line segment between two integers also divided into subparts to represent the rational number.

here given in the number line there are two integers 1 and 2 in which point C is situated.

The line segment between 1 and 2 is divided into 5 parts.

every subpart in line segment between 1 and 2 will be= the length of the subpart / total number of division

= (2-1)/5= 1/5

C point is present at a distance of 2 subparts from integer 1.

So the position of C will be = 1+(2)(1/5)= 1+(2/5)= 7/5 or 1 2/5

Therefore The position of C on the number line below is 7/5 or 1 2/5.
