B. y-4=-3/2(x+2)

C. y-1=-3/2(x+3)

D. y+1=-2/3(x+3)

Answers

Answer 1

Answer:

Answer:

Option B is correct.

$y-4=-(3)/(2)(x+2)$

Step-by-step explanation:

Point slope form:

The equation of straight line is given by:

$y-y_1=m(x-x_1)$ ......[1] where m is the slope and a point $(x_1, y_1)$ lies on the coordinate plane

From the given graph:

Consider two points i.e,

(-2, 4) and (2, -2)

Calculate slope:

Slope(m) is given by;

$m = (y_2-y_1)/(x_2-x_1)$

Substitute the given points we have;

$m = (-2-4)/(2-(-2)) = -(6)/(4) = -(3)/(2)$

Now, substitute the value of m and (-2, 4) in [1] we have;

$y-4=-(3)/(2)(x-(-2))$

$y-4=-(3)/(2)(x+2)$

Therefore, the equation is graphed here is $y-4=-(3)/(2)(x+2)$

Answer 2

Answer: B
it is a easy question. just find two points and find a good function
like these points: (0,1) . (2, -2)

What is the Volume of 10g of Gasoline?

Answers

Answer:

The Volume of 10 g of Gasoline is 14.286 ml approximately.

Step-by-step explanation:

Consider the provided information.

We need to find the Volume of 10 g of Gasoline.

Solve this with using the formula shown below:

Volume = mass/density

The density of gasoline is 0.7 g/ml.

Substitute the respective values in the above formula as shown:

$Volume=(10)/(0.7)$

$Volume=(100)/(7)$

$Volume=14.286$

Hence, the Volume of 10 g of Gasoline is 14.286 ml approximately.

10g /(0.7 g/ml) = 100/7 ml

= 14.2857...

Or 14.29 ml

xx6xx( this is only addition not multiplication)
Use 0-9 only once figure out the x

Answers

note:
3x means 3 times x or x+x+x
xx means x times x or x(x)

so
x+5+x+x+x+x+x+5=x+x+6+x+x
add like terms
6(x)+10=4(x)+6
not sure about the 0-9 part so I will disreagrd for now, please ask for correction later

6x+10=4x+6
subtract 4x from both sides
2x+10=6
subtract 10 from both sides
2x=-4
divide both sides by 2
x=-4/2=-2 (divide or multiply by different signs and get negative)
x=-2

At a baseball game, a vender sold a combined total of 170 sodas and hot dogs. the number of hot dogs sold was 50 less than the number of sodas sold. find the number of sodas sold and the number of hot dogs sold

Answers

Let the number of sodas sold be x and the number of hotdogs sold be y. We can assemble a system of equations from the information given and solve.

x+y=170 (We know that soda + dogs is 170)

x-50=y (We know that dogs is equal to 50 less than sodas)

We can use substitution to solve this system of equations.

x+y=170

Sub in the value of y from the second equation

x+(x-50)=170

2x-50=170

2x=220

x=110

We now know the number of sodas sold was 110. Lets now plug this value into the equation to solve for y.

x+y=170

110+y=170

y=60

So, there were 60 hotdogs sold and 110 sodas sold.

50 is 40% of what number?

Answers

$50-40\%\n x-100\%\n \n 50 \cdot 100=40x\n 40x=5000\n x=125\n Answer:Searched\ number\ is\ 125.$

The number 50 is 40 percent of the number 125.

let x be the unknown number.

To find the number that 50 is 40% of, set up the equation:

50 = 0.40 * x

To solve for x, divide both sides of the equation by 0.40:

50 / 0.40 = x

125 = x

Therefore, 50 is 40% of 125.

Which circles have an area of 9pi m2? Choose all answers that are correct. A. a circle with a radius of 3 m B. a circle with a diameter of 6 m C. a circle with a radius of 9 m D. a circle with a diameter of 9 m. Multiple Choice Question!

Answers

The formula of the area of a circle is
A = $\pi$ r²
given the area, find the radius

9 $\pi$ m² = $\pi$ r²
Divide by $\pi$

$\pi$ cancels out on both sides

9 = r²
Take square root on either sides
$√(9)$ = $√(r^2)$
3 m = r
The radius = 3 meters
Be careful for the units given
Its METERS

A. A circle with radius of 3 m
B. A circle with diameter of 6 m
(diameter = 2×radius, 2 × 3 = 6)
