4y + 9 = - 4y - 7. Please explain to me how to do it.

Greeley [361]3 years ago

You want to keep the variable on the left and number on right.

So, we need to get rid of 9 and -4y. Let's start with 9.

4y+9=-4y-7

Subtract nine from both sides.

4y=-4y-16

Now add 4y on both sides.

8y=-16

Finally, divide both sides by 8 to get y=-?.

8y/8=-16/8

Therefore, the answer is y=-2.

If angle YWZ = 17, what is angle WXY?
marusya05 [52]
We know that

step 1
if ∡YWZ=17°
then
∡XWZ=17°*2-----> 34°----> because triangle XWY and triangle YWZ are congruents

step 2
∡WXY=∡WZY-------> because triangle XWY and triangle YWZ are congruents
we know that 
<span>the sum of the internal angles of a triangle is 180 degrees
</span>so
180°=∡XWZ+2*∡WXY---------> ∡WXY=[180-∡XWZ]/2
∡WXY=[180-34°]/2-------> ∡WXY=73°

the answer is
∡WXY=73°

Help plz<br>6(2x - 11) + 15 = 3x + 12​
Ket [755]

Answer:

x = 7

Step-by-step explanation:

Lets do the brackets first,

6 × 2x = 12

6 × -11 = -66

------

Calculate the x constant:

12x - 3x = 9x

-------

Then the ones with no x:

-66 + 15 = -51

51 + 12 = 63

-------

Lastly, divide

63 ÷ 9 = 7

-------

Have a good day :)

The annual interest rate on a $10,000 loan is 18%. The exponential function that represents this is y = 10000(1.18t). Write the
Yuki888 [10]

Answer:

y=10000(1.015)^{12t}

option-B......Answer

Step-by-step explanation:

We are given

amount taken for loan =$10000

so, P=10000

annual interest rate =18%

r=0.18

now, we can use formula

y=P(1+\frac{r}{n} )^{nt}

Since, it is compounded monthly

so, n=12

we can plug values

y=10000(1+\frac{0.18}{12} )^{12t}

y=10000(1.015)^{12t}

Write the equation of the circle with center (2, -3) and a radius of 4.
harkovskaia [24]
C(h,k) radius(r)
C(2,-3) r=4

(x-h)^2 + (y-k)^2 = r^2
(x-2)^2 + (y--3)^2 = 4^2
(x-2)^2 + (y+3)^2 = 16

therefore, the answer is D
