puteri [66]

Answer:

Equation: y = -3x -2

Graph: Attached below ↓↓↓↓↓

Step-by-step explanation:

The equation is y = -3x + b

We need B at this point.

Since we have a point given to us,( -2, 4)we can input the x and y

Solve:

4 = -3(-2) + b

4 = 6 + b

b = -2

So the equation we have is y = -3x -2

Let's graph the line.

We go 2 units below the x-axis, because the y-intercept is -2, and the slope is -3, so we go down 3 units, and to the right 1.

Which of the quadratic functions has the widest graph? y = 0.3x2 y = –4x2
Alenkinab [10]
A vertical stretching is the stretching of the graph away from the x-axis.
A vertical compression is the squeezing of the graph towards the x-axis.
A compression is a stretch by a factor less than 1.

For the parent function y = f(x), the vertical stretching or compression of the function is a f(x). 

If | a | < 1 (a fraction between 0 and 1), then the graph is compressed vertically by a factor of a units.
If | a | > 1, then the graph is stretched vertically by a factor of a units.

For values of a that are negative, then the vertical compression or vertical stretching of the graph is followed by a reflection across the x-axis.

Thus, the equation with the widest graph is 0.3x^2.

From a rectangular metal sheet whose measure 30cm×20cm, a circular portion whose radius is 10.5cm is cut off .Find the area of r
miskamm [114]

Answer:

254 cm²

Step-by-step explanation:

Calculate first  the total area

A = 30*20 = 600 cm²

Then calculate the area of the cercle

A= 10.5²*π = 346.36≈346 cm²

Then substract the area of the circle from the total one:

600-346= 254 cm²

Gwar [14]

Answer:

Each = 3\frac{1}{3}

Step-by-step explanation:

Given

Balls = 4\ pack

Gums = 5\ each

First we need to determine the number of gums

Total = 4 * 5

Total = 20

Divide 20 among 6 friends

Each = \frac{20}{6}

Each = 3\frac{1}{3}

Hence;

Each friend gets 3\frac{1}{3}\ gum
