7th-grade math slope problem.

Answer:

130units²

Step-by-step explanation:

The question lacks the required figure. Find the figure attached:

Given

Area of square 1 = 250units²

Area of square 3 = 120units²

Area of a square = L²

L is the length of one side of the square

Get the length of each side of the square

For square 1

A1 = L1²

250 = L1²

L1 = √250

Get that of square 3

A3 = L3²

120 = L3²

L3 = √120

Required

Area of square 2

Before we can get the area of square 2, we need to get the side length using pythagoras theorem

L₂² = L₁² - L₃²

L₂² = (√250)²-(√120)²

L₂² = 250-120

L₂²  = 130

Since the area of the square A is L₂² , then the required area is 130units²

Answer:

The slope is equal to [tex]\frac{2}{3}[/tex] . So the right answer is A.

Step-by-step explanation:

We know that if we are given to points of a function we can find out its slope by using the following formula....

[tex]m = \frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

Where m is the slope,  [tex]x_{1}[/tex] and [tex]y_{1}[/tex] are the coordinates of the first point, [tex]x_{2}[/tex] and [tex]y_{2}[/tex] are coordinates of the second point.

Let (-4, 2) be [tex](x_{1} , y_{1})[/tex]

Let (-16, - 6) be [tex](x_{2}, y_{2} )[/tex]

then......

The slope of the line will be [tex]\frac{2}{3}[/tex] i.e. option A is the correct answer.

Slope is or gradient of a line is a number that describes both the direction and the steepness of the line.

Slope [tex](m) =\frac{y_{2}-y_{1} }{x_{2}-x_{1}}[/tex]

We have,

Points (-4, 2) and (-16, -6)

i.e.

x₁ = -4,  x₂ = -16,

And,

y₁ = 2,   y₂ = -6

Now,

Using the above mentioned formula,

Slope [tex](m) =\frac{y_{2}-y_{1} }{x_{2}-x_{1}}[/tex]    

i.e.

Slope [tex](m) =\frac{-6-2}{-16-(-4)}[/tex]

On solving we get,

Slope [tex](m) =\frac{-8}{-12}=\frac{2}{3}[/tex]

So, the slope pf the given points is  [tex]\frac{2}{3}[/tex] .

Hence, we can say that the slope of the line will be [tex]\frac{2}{3}[/tex] i.e. option A is the correct answer.

Answer:

2

Step-by-step explanation:

the y intercept is at 2

Answer:

Here we can not see the options, so i will find the graph by the equation alone.

We start with:

Ix - 1I < 4

We could rewrite this as:

-4 < (x - 1) < 4

Now we can add 1 in the 3 parts, to get:

-4 + 1 < x - 1 + 1 <  4 + 1

-3 < x < 5

This means that the graph will be such that:

x >  -3   (this is a dashed line at x = 3, and we shade the part in the right of that line)

and:

x < 5   (this is a dashed line at x = 5, and we shade the part in the left of that line)

The graph would look something like the one below

(If the graphs are only in one axis, you should see a white dot at x = -3, than a colour line that goes to the right until the point x = 5, where we have another white dot)

Given:

The vertices of a triangle are P(4,1), Q(2,-8), and R(-8,1).

To find:

The vertices of the image reflected across the y-axis.

Solution:

The vertices of a triangle are P(4,1), Q(2,-8), and R(-8,1). It is reflected across the y-axis.

If a figure is reflected across the y-axis, then

[tex](x,y)\to (-x,y)[/tex]

Using this rule, we get

[tex]P(4,1)\to P_1(-4,1)[/tex]

[tex]Q(2,-8)\to Q_1(-2,-8)[/tex]

[tex]R(-8,1)\to R_1(8,1)[/tex]

So, the vertices of the image are [tex]P_1(-4,1), Q_1(-2,-8), R_1(8,1)[/tex].

Therefore, the correct option is B.

Note: Options are not in proper form.

Answer:

P'(–4, 1), Q'(–2, –8), and R'(8, 1)

Step-by-step explanation:

all of the others are lower than 0

Answer:

A coefficient is a number in front of a variable. For example, in the expression x 2-10x+25, the coefficient of the x 2 is 1 and the coefficient of the x is -10. The third term, 25, is called a constant.

Answer:

The value of x = 1

Step-by-step explanation:

Given

To determine

x = ?

Using the trigonometric ratio

cos Ф = adjacent / hypotenuse

here

Ф = 45°

adjacent of 45° = x

hypotenuse = √2

so substituting Ф = 45°  adjacent = x and hypotenuse = √2  in the equation

cos Ф = adjacent / hypotenuse

[tex]\cos \left(45^{\circ \:}\right)=\frac{x}{\sqrt{2}}[/tex]

switch sides

[tex]\frac{x}{\sqrt{2}}=\cos \left(45^{\circ \:}\right)[/tex]

Multiply both sides by 2

[tex]\frac{2x}{\sqrt{2}}=2\cos \left(45^{\circ \:}\right)[/tex]

[tex]\sqrt{2}x=\sqrt{2}[/tex]             ∵  [tex]\cos \left(45^{\circ \:}\right)=\frac{\sqrt{2}}{2}[/tex]

Divide both sides by √2

[tex]\frac{\sqrt{2}x}{\sqrt{2}}=\frac{\sqrt{2}}{\sqrt{2}}[/tex]

[tex]x=1[/tex]

Therefore, the value of x = 1

- the type of pair is vertical angle.

- to find x:

-- vertical angles are equal.

4x + 10 = 5x - 1

10 = x - 1

x = 11

Answer:

the slope is 1

you find two points that are directly on an intersection of the grid. and then count rise/run

rise is going up and down and run is left and right

start at the point you found furthest to the left and count to the next point that's to the right.

if you have to go down to find it or left to find it, the slope is negative

in this case. theres a point at (-1,0) and (0,1)

you have to count up one and right one, making the slope 1/1 or simplified to 1
