X= -3
Explanation: add 2x to both sides of equation. -7x+2x = -2x+15+2x which ends up equaling -5x=15 then divide both sides by -5. -5x=15 |
-5 -5 | which gets you -3 after dividing

Answer:

-3

Step-by-step explanation:

-7x=-2x+15

collect like terms

-7x+2x=15

I need help on question 16 &amp; 17! <br> I don’t really understand how to solve it.
Sidana [21]

Answer:

y = 11

x = 8.6

Step-by-step explanation:

The small triangle with 30,32,y looks like right triangle

so according to formula a^2 + b^2 = c^2

so 30^2 + y^2 = 32^2

900 + y^2 = 1024

y^2 = 124 => y = 11

The larger triangle also looks like a right triangle

so according to formula a^2 + b^2 = c^2

(30 + 10)^2 + 22^2 = (32 + x)^2

1600 + 44 = (32 + x)^2

so (x + 32)^2 = 1644

x + 32 = 40.55

x = 40.55 = 32 = 8.55 = 8.6

Which function represents exponential decay?
geniusboy [140]

Answer:

a

Step-by-step explanation:

We are looking for an exponential function y=a(r)^x where r is less than 1.

a works because it is in the form y=a(r)^x where r is less than 1.

b is in the form y=a(r)^x but r is more than 1.

c. and d. are not even exponential functions.

c. is a polynomial

d. is a constant polynomial (no variable)

Angelina_Jolie [31]

Answer:

The image will be DCBAFE

Step-by-step explanation:

A polygon with six sides is called a hexagon

In this question first identify the midpoints of BC and EF using perpendicular bisector.

This should be followed by joining the two midpoints with a straight edge to draw the mirror line.

The  points above the mirror line F,A and B will be reflected below the mirror line.The points below the mirror line C,D and E will be reflected above the mirror line.

The image will be DCBAFE
