First, let's solve the inequality
2.9 (x+8) < 26.1
2.9x + 23.2 <26.1
2.9x < 26.1 -23.2
2.9x <2.9
dividing both sides by 2.9 we get:
x < 1
so, it is the last numberline graph, because it contains an empty circle at 1 on the numberline, which means it doesn't include 1. but all numbers less than 1

A. What are the coordinates of the vertices of the triangle below?

Viktor [21]

Answer:

Solution given:

<u>A.coordinate are</u>

A(-2,3)

B(0,-3)

C(4,5)

<u>B</u><u>.</u><u>Each</u><u> </u><u>length</u><u> </u><u>are</u><u> </u><u>:</u>

we have

length $\sqrt{(x2-x1)²+(y2-y1)²}$

now

AB: $\sqrt{(-2-0)²+(3+3)²}$ = $2\sqrt{10}$ units

BC: $\sqrt{(0-4)²+(-3-5)²}$ = $4\sqrt{5}$ units

AC: $\sqrt{(-2-4)²+(3-5)²}$ = $2\sqrt{10}$ units

<u>C.</u><u> the </u><u>figure</u><u>:</u>

<u>By</u><u> </u><u>using</u><u> </u><u>Pythagoras</u><u> </u><u>law</u>

base[b]=AB=perpendicular [p]=AC

hypotenuse [h]=BC

we have

h²=p²+b²

substituting value

( $4\sqrt{5}$ )²=2p²

16*5=2*( $2\sqrt{10}$ )²

80=2*4*10

80=80

<u>SO</u><u> </u><u>IT</u><u> </u><u>IS</u><u> </u><u>RIGHT</u><u> </u><u>ANGLED</u><u> </u><u>ISOSCELES</u><u> </u><u>TRIANGLE</u><u>.</u>

What is 2/5 of 8 ( i have no idea what to do... Please help ! )

vekshin1

<span>Since 8 is a whole number and ⅖ is a fraction, it doesn’t make it that complicated. Fraction is just like division, you just make the number on the top as your dividend and the number below as your divisor. First, get the quotient of the fraction ⅖ which is 0.4. Since you are looking for the ⅖ of the whole number 8, you need to multiply it. The quotient 0.4 will be multiplied to 8. Or you can simply multiply 2 by 8 and divide it to 5. The answer would be 3.2</span>
