Answer:

r=9⅓

Step-by-step explanation:

(10,r). (4,-3)

(x¹,y¹) (x²,y²)

gradient=y²-y¹

x²-x¹

4= -3-r

3 4-10

multiply both sides by 3(4-10)to remove the denominators.

3(4-10)× 4 = -3-r ×3(4-10)

3 4-10

(4-10)×4= (3-r)×3

16-40=9-3r

put the liketerms together

note* signs(- +) change when they cross the equal sign(=)

3r=4+40-16

3r=28

divide both sides by 3

r=28/3.

r=9⅓

Find the area of the trapezoid

Sergeeva-Olga [200]

Answer:

Step-by-step explanation:

Formula

$\frac{1}{2} \times h \times (sum \: of \: parallel \: sides(b1 + b2))$

Your scale is 2cm to 2units therefore the parameters are as follows

h=4

b1=9

b2=13

$\frac{1}{2} \times 4 \times (9 + 13)$

$\frac{1}{2} \times 4 \times 22$

$\frac{1}{2} \times 88$

$\frac{88}{2} \\ = 44$

How do you simplify on number 1?

Dennis_Churaev [7]

Okay. On the part that's not the whole number, see how the top number is BIGGER than the bottom? That means that it's not simplified. In order to make it simplified, you have to take a whole out of the pat that's not a whole number. Since the denominator is 12, the whole is 12/12. So, subtract it from the 13/12.

13/12-12/12=1/12

Now, since you found a whole inside of the fraction you have to add 1 to the whole number.
5+1=6

So, the answer is 6 1/12.

Thanks for the points!

What is the solution to 5x+9-3x=18+15 A.x=8 B.x=12 C.x=21 D.x=3

Vlad [161]

Your answer will be B) x=12

1)5x-3x
2) move 9 to the other side (change signs)
3)18+15-9
4) 2x= 24 (divide 2 from both sides
5)x=12

hope this helps
