Answer:

The equation's formula:

$y - y1 = m(x - x1) \\$

Remember that y intercept's x coordinate=0

So:

$y - 7 = - \frac{4}{5} (x - 0) \\ y - 7 = - \frac{4}{5} x \\ y = - \frac{4}{5} x + 7 \: or \: y = - 0.8x + 7$

Good luck!

Each pound of fruit costs $4. Write an expression that shows the total cost of the fruit. Use the variable you identified in que

vovangra [49]

Answer:

$ $4f$

Step-by-step explanation:

Let's assume $f$ represents the number of pounds of fruit.

We need to multiply the number of pounds of fruit by the cost per pound.

This is $ $f * 4$ , or in a simpler form, $ $4f$ .

givi [52]

Answer:

19/5

Step-by-step explanation:

Aquí, queremos escribir el número total de millas que Hans corrió en forma de una fracción impropia.

Para hacer esto, agregamos todas las millas recorridas.

Matemáticamente, eso sería 3 + 4/5 = 3 4/5 Esta es la forma de fracción mixta.

La fracción impropia es así (5 * 3) + 4/5 = 19/5

If y is directly proportional to x and y = 5 when x =2, what is the value of y when x=6

sammy [17]

Answer:

y=15

Step-by-step explanation:

The formula for direct variation is

y = kx

5 =k*2

Solve for k

Divide by 2

5/2 = k

y = 5/2 x

Now we substitute x=6

y = 5/2(6)

y = 15

Which statements are true about the circle shown?

CaHeK987 [17]

Answer:

Among the five statements,statement 1 and 4 are true for the circle shown.

Step-by-step explanation:

Given:

An image is attached here.

A circle with radius = 15.4 m

We ave to find the diameter,circumference and relationship between the two.

Formula to be used:

⇒ Diameter of a circle = 2r

⇒ Circumference = 2πr

Lets find the values.

Diameter = $2r=2(15.4) = 30.8$ m
Circumference = $2\pi r =2(3.14)(15.4)=96.7$ m
Relationship = $\frac{circumference}{diameter}$ $=$ $\frac{96.7}{6}$ $=3.1$

We can say that a little more than 3 diameters could be wrapped around the circle.

From the drop down our choices are.

The diameter of the circle is 30.8 m.
The approximate circumference of the circle ,rounded to the nearest tenth is 96.7 m.

Option 1 and 4 are the right choices.
