$\huge\sf \pink{A} \sf \red{n} \sf \orange{s} \sf \blue{w} \sf \green{e} \sf \purple{r}$

It is an isosceles triangle.

$\huge\sf \pink{R} \sf \red{e} \sf \orange{a} \sf \blue{s} \sf \green{o} \sf \purple{n}$

Because it's 2 of sides are equal and one is different.

$\huge\sf \pink{V} \sf \red{e} \sf \orange{r} \sf \blue{i} \sf \green{f} \sf \purple{i} \sf \red{c} \sf \pink{a} \sf \blue{t} \sf \green{i} \sf \purple{o} \sf \orange{n}$

<h3>Remember,</h3>

A triangle with two sides equal is known as isosceles triangle.

This triangle have two sides with equal length.

Each whole number from 0 to 9 is paired with its opposite. is this a function or not

dimaraw [331]

A function has the property that each element of the domain maps to only one element. For example, if there's ever the case where a relation includes point (1,2) and (1,3) then that relation is not a function. So for each case write down all the points as described. If one point in the domain ever maps to two different points, then it's not a function

A trains travel is represented by the equation y= 17.5x where y represents the total number of miles the train travel in x hours

MakcuM [25]

Answer:
Jesse - 150 miles per hour.
Step-by-step explanation:
On the graph, it shows that the rise is 140 and the run is 1. 140/1 is 140, making the slope for Khalid is 140. The equation (y = 150x) shows that the slope is 150 (y = mx). Since 150 is greater than (>) 140, Jesse's train is more faster than Khalid since she is moving at 150mph rather than 140mph.

Em 1 Graph the system of equations. { x−y=6 ,4x+y=4

muminat

Graphing the system of equations is shown in figure attached.

Solution set is (2,-4). The lines will intersect at (2,-4)

Step-by-step explanation:

We need to graph the system of equations. $x-y=6 ,4x+y=4$

First we will find value of x and y

Let:

$x-y=6\,\,eq(1)\\4x+y=4\,\,eq(2)$

Add eq(1) and eq(2)

$x-y=6\,\,\\4x+y=4\,\,\\------\\5x=10\\x=10/5\\x=2$

Putting value of x in eq(1) and finding y

$x-y=6\\2-y=6\\-y=6-2\\-y=4\\y=-4$

So, y=-4

Graphing the system of equations is shown in figure attached.

Solution set is (2,-4). The lines will intersect at (2,-4)

True or false, the decimal form of 3 3/8 is 3.38

Charra [1.4K]

False. The decimal form can be found by doing 3 + (3 ÷ 8). It would be 3.375.

Hope this helps!

Nick's telephone company charges $0.07 per minute for weekend calls and $0.08 per minute for calls made on weekdays. This month

DerKrebs [107]

So pretend weekend calls is x and weekday calls are y.

the formulas is x + y = 610
                        0.07x + 0.08y = 48.05

So, x = 610 - y

Then, substitute x into the second equation.

0.07(610 - y) + 0.08y = 48.05
42.7 - 0.07y + 0.08y = 48.05
                        0.01y = 5.35
                               y = 535

Then substitute y into the first equation.

x + 535 = 610
          x = 75

Just to be sure, substitute x and y into the second equation.

0.07(75) + 0.08(535) = 48.05
             5.25 + 42.80 = 48.05
                        48.05 = 48.05

So, on weekends, he used 75 minutes.
On weekdays, he used 535 minutes.
