Answer:

36 / 21 = h / 168 so h = 168 (12 / 7)

Step-by-step explanation:

i dont know how to explain it

* means multiply

y = 2 * 7 + 7 = 14 + 7 = 21 -> (7,21)

y = 2 * 0 + 7 = 0 + 7 = 7 -> (0,7)

y = 2 * -5 + 7 = -10 + 7 = -3 -> (-5,-3)

Answer:

slope = 2 because it goes up by 2 and across 1

10 = 2(1)+b

10=2+b

-2   -2

b = 8

y intercept = 8

equation: y = 2x+8

yes it is proportional because it has a constant rate of change or slope

110/2 = 55 miles

you travel 55 miles an hour

multiply that by 5 to get your answer

equals 275 miles

Hope this is helpful.

Answer:

275 miles in 5 hours

Step-by-step explanation:

110/2 is 55. 55 is 1hour so multiply 55 times 5 and thats your answer.

Answer: A multiple is a number that can be divided by another number a certain number of times without a remainder. A factor is one of two or more numbers that divides a given number without a remainder. Therefor, 50 could not be a multiple of 6.

Step-by-step explanation:

Answer:

a) 740 × 233 = 172420

In the number 740, there's an zero being added so the answer will have a zero too.

b) 74 x 2.33 = 172.42

In the number 2.33, the decimal place is two to the left so the answer needs to have a decimal that is to to the left.

Answer:

202.5

Step-by-step explanation:

Start by finding the area of the triangle part using the lengths of 9 , 9 , and 5

That gives you 22.5

Then find the area of the rectangle part using the sides of 20 and 9

This gives you 180

When you add them you get 202.5

I hope that this helps!!

Answer: In decimal the answer is 4.5 but if in fraction the answer is 4 1/2

√44

2 Real Roots

Looking at the image attached, the discriminant is the value under the square root.

In the equation given:

a = 1

b = -8

c = 5

The discriminant is therefore:

√(b²- 4ac) = √(-8²- (4*1*5)) = √(64-20) = √44

√44 is a positive number. Because it is positive, there must be 2 real roots.

If it were negative, there would be 2 imaginary roots.

If it were zero, there would be 1 real root.

Answer:

Step-by-step explanation:

from how the sides are marked it is an equilateral triangle, to see it does not seem. assuming that it is equilateral it has 3 angles of 60 ° for which 4x - 20 = 60

4x - 20 = 60

4x = 80

x = 80 : 4

x = 20

-------------------

4 * 20 - 20 = 60°

Answer:

y = 2x - 3/4  Answer b

Step-by-step explanation:

slope intercept form is

m is the slope  = 2

b is the y-intercept = -3/4

therefor

y = 2x - 3/4  Answer b

Answer:

Greater than can be defined as an inequality used to compare two or more numbers, quantities or values. It is used when a quantity or number is bigger or larger than the second or rest quantities or numbers.

Step-by-step explanation:

La casa de Rodrigo está dos cuadras a la derecha de la casa de Andrés.

En esta pregunta, debemos leer el enunciado y obtener las ecuaciones equivalentes antes de obtener su solución. En este caso tenemos las siguientes dos ecuaciones:

(i) La casa de Camilo está a 4 cuadras a la derecha de la casa de Andrés.

[tex]c - a = 4[/tex] (1)

(ii) La casa de Rodrigo está a 2 cuadras a la izquierda de la casa de Camilo.

[tex]r - c = -2[/tex] (2)

Si sumamos (1) con (2), entonces obtenemos la siguiente ecuación entre las casas de Andrés y Rodrigo:

[tex]r - a = 2[/tex]

En síntesis, la casa de Rodrigo está dos cuadras a la derecha de la casa de Andrés.

Ah sorry I got it wrong, dear

Hii!

After 3.5 days, the height of the plant is 5.75 centimeters.

h = 0.5(3.5) + 4

h = 1.75 + 4

height = 5.75 cm after 3.5 days.

The height of the plant is 6.25 centimeters after 4.5 days.

6.25 = 0.5d + 4

6.25 - 4 = 0.5d - 4

2.25 = 0.5d

2.25/0.5 = 0.5d/0.5

4.5 = d

days = 4.5

Thus, the height of the plant is 6.25 centimeters after 4.5 days.

After 3.5 days, the height of the plant is 5.75 centimeters and the height of the plant is 6.25 centimeters after 4.5 days.

A straight line is a combination of endless points joined on both sides of the point.

The slope 'm' of any straight line is given by:

[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]

The equation of the line is:

h = 0.5d + 4

After rewriting the function:

f(x) = 0.5x + 4

Plug x = 0

f(0) = 4 cm

f(1) = 4.5 cm

f(2) = 5 cm

f(3) = 5.5 cm

f(4) = 6 cm

f(5) = 6.5 cm

Plug x = 3.5 days

f(3.5) = 5.75 cm

Plug f(x) = 6.25

6.25 = 0.5x + 4

2.25 = 0.5x

x = 4.5 days

Thus, after 3.5 days, the height of the plant is 5.75 centimeters and the height of the plant is 6.25 centimeters after 4.5 days.
