Answer:

Not a triangle

Step-by-step explanation:

Side lengths do not adhere to the triangle inequality theorem. Which states that the sum of the side lengths of any 2 sides of a triangle must exceed the length of the third side.

Not a triangle because the two smaller numbers do not add up to a bigger number than 15

Answer:

Please find the answer in the image attached

Step-by-step explanation:

Here we are asked to solve a pair of linear inequalities.

In order to do so , we are first required to plot the two lines with inequalities taking into considerations.

Hence let us plot

x+2y=-4 and 5x+2y=4

let us first plot x+2y=-4

$y=\frac{-4-x}{2}$

let us plot a table for the same for two random values of x and putting them into above equation

x y

0 -2

2 -3

Let us now plot these points and join the line .

Let us check whether (0,0) satisfies the in equation or not

0+2(0)≤-4

0≤-4

Which is not true , Hence we shade the portion divided by our line which does not contain (0,0)

Now let us plot the second line 5x+2y=4

$y = \frac{4-5x}{2}$

let us plot a table for the same for two random values of x and putting them into above equation

x y

0 2

1 -0.5

Let us now plot these points and join the line .

Let us check whether (0,0) satisfies the in equation or not

5(0)+2(0)≤4

0≤4

Which is true , Hence we shade the portion divided by our line which does contain (0,0)

Please refer to the image attached with this answer.

now the commonly shaded area as shown in the image will be our solution to the above pair of in equations.

A line has a slope of –5 and a y-intercept of (0, 3). What is the equation of the line that is perpendicular to the first line a

neonofarm [45]

Slope-intercept form:
y=mx+b
m=slope
b=y-intercept

Data of the first line:
m=-5
b=y-intercept=3 (y-intercept=it is the value of "y" when x=0)

y=-5x+3

A line perpendicular to the line y=mx+b will have the following slope:
m`=-1/m

Therefore: the line perpendicular to the line y=-5x+3 will have the following slope:
m´=-1/(-5)=1/5

Point-slope form of a line: we need a point (x₀,y₀) and the slope (m):
y-y₀=m(x-x₀)

We know, the slope (m=1/5) and we have a point (3,2) therefore:
y-y₀=m(x-x₀)
y-2=1/5(x-3) (point-slope form)
y-2=(1/5)x-3/5
y=(1/5)x-3/5+2
y=(1/5)x+7/5 (slope-intercept form)

Answer: the line perpendicular to the first line will be: y=(1/5)x+7/5

Can someone help me with this

Considering the given graph of the function, we have that:

Function Notation: f(1) = -3.

Ordered pair: (1,-3).

Verbal statement: If x is equal to -1, then the value of f(x) is equal to -3.

<h3 /><h3>How to find the numeric value of a function looking at it's graph?</h3>

To find the numeric value of the function, we get a value of x(horizontal axis), and then look at the corresponding value y(vertical axis), then y = f(x).

In the graph of this function, we have that when x = 1, y = -3, hence:

Function Notation: f(1) = -3.

Ordered pair: (1,-3).

Verbal statement: If x is equal to -1, then the value of f(x) is equal to -3.
