Y= 2.5x+ 5.8 when x = 0.6 pls find the function

adoni [48]

You’d plug in the 0.6 for x. so you’d multiple 0.6 times 2.5 then you’d get 1.5 then you’d add 1.5 plus 5.8 and get 7.3

Can someone help me with numbers 10,11,12 plzzz show work I need help plzzzz

leonid [27]

Answer:

10. JL = 4

11. m∠KML = 45°

12. see below for a full list of angle measures; x = 30

Step-by-step explanation:

10. In the square, the diagonals are both the same length, and point N is their midpoint. That means ...

KM = 2·JN

4z -8 = 2(4z -10) . . . . substitute the given expressions

4z -8 = 8z -20 . . . . . .eliminate parentheses

12 = 4z . . . . . . . . . . . .add 20-4z to both sides

KM = 12 -8 = 4 . . . . . substitute for 4z in the expression for KM

JL = KM = 4

11. All the sides and angles that look like they're the same measure are the same measure. Any angle not 90° is 45°. m∠KML = 45°

12. For this, you make use of the properties of a rhombus. The diagonals of a rhombus are perpendicular bisectors of each other, so all of the angles where the diagonals meet are 90°.

Then within each triangle, the angles not 50° are their complement, 40°.

Angles in opposite corners are congruent to each other, and each diagonal bisects the corner angle. So ...

∠GHJ = ∠GKJ = 100°

∠GHK = ∠JHK = ∠GKH = ∠JKH = 50°

∠HGK = ∠HJK = 80°

∠HJG = ∠KJG = ∠KGJ = ∠KJG = 40°

We have already said the central angle is 90°, so ...

(5x -60)° = 90°

x -12 = 18 . . . . . . divide by 5°

x = 30 . . . . . . . . add 12

— 2х = 5 + 10 4х + 10 = — 20

blondinia [14]

Answer:

[-7½, 0]

Step-by-step explanation:

The top equation is pretty much already done for you:

-2x = 15 [Divide by -2]

x = -7½

Now of course, you have to check the bottom equation:

4[-7½] + 10 = -20

-30 + 10 = -20 ✅

I am joyous to assist you anytime.

A toy rocket launched into the air has a height ( h feet) at given time ( t seconds) as h= -16^2+160t until it hits the ground.

Gennadij [26K]

Answer:

$t = \frac{53}{32}$

Step-by-step explanation:

$h=\:-16^2+160t$

$9=\:-16^2+160t$ $substitute$

$-16^2+160t=9$

$-256+160t=9$

$-256+160t+256=9+256$

$160t=265$

$\frac{160t}{160}=\frac{265}{160}$

$t=\frac{53}{32}$

At $\frac{53}{32}$ seconds it is at a height of 9 ft.

The sum of two rational numbers is -5 if one of the number is -13/6 find the other number

Vladimir79 [104]

Answer:

$Let \ the \ number \ be = x\\sum \ of \ 2 \ rational \ numbers = -5\\\\x + \frac{-13}{6} = -5\\\\x - \frac{13}{6} = -5\\\\$

$x = -5 + \frac{13}{6} = \frac{-30 + 13}{6} = -\frac{17}{6}$

The other rational number = -17/6
