What is the y and x intercept and can i get a step by step explanation

Answers

Answer:

the slope is -3/2, and the y-intercept is 5/2.

Step-by-step explanation:

3x + 2y = 5

putting it into a y = mx+b form,

2y = -3x + 5

y = -3/2x + 5/2

the slope is -3/2, and the y-intercept is 5/2.

Answer:

y-intercept= 2.5

x- intercept= 1.666666666..... or 5/3

Step-by-step explanation:

1. Move variable to other side.

3x+2y= 5

-3x        -3x

2y= -3x+5

2. Divide each side by 2.

-3/ 2 = -1.5

5/2 = 2.5

y= 1.5x+2.5

y= mx+b

b= y-intercept

b=2.5

3. Replace y with 0 to solve for x intercept.

3x+ 2 x 0 = 5

3x= 5

5/3 = x

Brianna bought snacks for her team's practice. She bought a bag of

oranges for $2.63 and a 8-pack of juice bottles. The total cost before

tax was $16.07. Write and solve an equation which can be used to

determine x, how much each bottle of juice costs?

Answers

Answer:

$1.68

Step-by-step explanation:

The total cost is $16.07 and there was 2 things bought- the oranges and the juice bottles. to make it easier to find the cost of the juice bottles, we'll subtract the cost of the oranges (2.63) from the total (16.07), which gives us 13.44. this number represents the total cost of only the bottles. To find out the cost if each individual bottle, you need to divide the total (13.44) by the number of bottles (8). This gives us 1.68, so the cost of each bottel is $1.68

Taylor has dd dimes and qq quarters. She has a maximum of $4 worth of coins altogether. Write this situation as an inequality.

Answers

Answer: .10d+.25q<_ 4

Step-by-step explanation:

d= dimes and q = quarters

dimes are worth .10 and quarters are worth .25

The inequality for the given situation is

0.1d + 0.251 ≤ 4

What is inequality?

It shows a relationship between two numbers or two expressions.

There are commonly used four inequalities:

Less than = <

Greater than = >

Less than and equal = ≤

Greater than and equal = ≥

We have,

10 dimes = 1 dollar

1 dime = 0.1 dollar

4 quarters = 1 dollar

1 quarter = 0.25 dollar

Now,

The maximum amount is $4.

So,

0.1d + 0.251 ≤ 4

Thus,

The inequality is 0.1d + 0.251 ≤ 4.

In Zimbabwe the rate of inflation hit 90 sextillion percent in 2009, with prices increasing tenfold every day. At that rate, how much
would a $14 wool blanket cost five days later?

Hint: Use the following equation to calculate future price: Future price = (current price) * (inflation rate)^t where t the number of days
in the future.

Instructions: Round your response to one decimal place.

Answers

Five days later the wool blanket would cost $ 1,400,000.

Given that in Zimbabwe the rate of inflation hit 90 sextillion percent in 2009, with prices increasing tenfold every day, to determine, at that rate, how much would a $ 14 wool blanket cost five days later, the following calculation must be performed:

Future price = (current price) * (inflation rate) ^ number of days

X = 14 x 10 ^ 5

X = 14 x 100,000

X = 1,400,000

Therefore, five days later the wool blanket would cost $ 1,400,000.

write an equation of a line parallel to the line y=-2x+8 and passes through the point (-1,-3)​

Answers

Answer: y=–2x–5

Step-by-step explanation:

The equation of a straight line:

y=mx+c

m must be the same for the two lines to be parallel.

y=mx+c

y=–2x+8 → m=–2

For a new equation:

x=–1, y=–3, m=–2, c=?

y=mx+c → –3=–2×(–1)+c

–3=2+c

c=–5

So:

y=–2x–5

Answer:

See below

Step-by-step explanation:

GivenR is the midpoint of SQ and PTTo proveΔPQR ≅ ΔTSRSolution

R is the midpoint of SQ

SR = 1/2SQ and RQ = 1/2SQ ⇒ SR ≅ RQ

R is the midpoint of PT

PR = 1/2PT and RT = 1/2PT ⇒ PR ≅ RT

SQ and PT intersect at point R ⇒

∠PRQ ≅ ∠TRS as vertical angles

Triangles PQR and TSR have two sides and the included angle congruent, therefore:

ΔPQR ≅ ΔTSR,

as per SAS congruence postulate

If two sides and the included angle in one triangle are congruent to two sides and the included angle in another triangle, then the two triangles are congruent
