simplify the expression -9x-8+4x+7

Answer:

[tex]V=15.62\ cm^3[/tex]

Step-by-step explanation:

The volume of a cube is given by the formula :

V = s³, where s represents the side length of the cube

The side length of Marie's cube is [tex]2\dfrac{1}{2}\ cm[/tex]. We need to find the volume of her cube. For this, we can use the formula of the volume of a cube such that,

[tex]V=(2\dfrac{1}{2})^3\\\\=(\dfrac{5}{2})^3\ cm^3\\\\=\dfrac{125}{8}\ cm^3\\\\=15.62\ cm^3[/tex]

So, the volume of her cube is [tex]15.62\ cm^3[/tex].

Answer:

D

Step-by-step explanation:

because the slope is 7 and y-int is 6

so, u must use y=mx+c

just replace the slope and y-int into that formula

Answer:

CB=18

And the measure of angle BDA is 21 degrees

Step-by-step explanation:

Answer: ∠BDA = 21; CB = 30

have:

sin ∠BDC = [tex]\frac{4x+6}{BD}[/tex]

sin ∠ADB = [tex]\frac{7x-12}{BD}[/tex]

because ∠BDC = ∠ADB => sin ∠BDC = sin ∠ADB

=> [tex]\frac{4x+6}{BD}=\frac{7x-12}{BD}[/tex]

=> 4x + 6 = 7x -12

<=> 3x = 18

<=> x = 6 => CB = 4.6 + 6 = 30

Answer:

f(x)=-4x+-2

Step-by-step explanation:

Slope intercept form: f(x)=mx+b

m=slope=[tex]\frac{rise}{run}[/tex]

b=y-intercept=y value when x=0

Answer:

A

-2 < x ≤ 3 (All x values between -2 and 3; excluding -2 and including 3)

Step-by-step explanation:

I feel the answer is A because from what we know, domain is the x-intercept or x. So both C and D are not the answer because the y-intercept is not the domain, the y-intercept is the range. Next I looked at both A and B, well, if you look closely answer choice A says "excluding -2 and including 3" and choice B says "including -2 and excluding 3". I also seen on the graph that the point of (3,3) has a filled in dot and the point at (-2,-1) has an opened dot. A filled in dot always means you either have a ≥ (greater than or equal to sign) or a ≤ (less than or equal to sign). While an opened dot always means you just have < (greater than) or a > (less than) sign. So the correct answer is A!! Hope you have a fantastic rest of your day! :)))

Answer:

22c+36

Step-by-step explanation:

3+11(2c+3)

3+22c+33

3+33+22c

36+22c or 22c+26

Hey there!

In order to simplify this expression, all we have to do is distribute 11 by multiplying it times 2c and 3 and then combining like terms,

3+22c+33

As you can see, 3 and 33 are like terms; in order to simplify the expression, we should add them together.

36+22c

or

22c+36

Hope everything is clear.

Let me know if you have any questions!

Answer:

y = -24

General Formulas and Concepts:

Pre-Alg

Step-by-step explanation:

Step 1: Define

y = -4x² - 8

x = 2

Step 2: Solve

Answer:

Given, input (x) is 2,

[tex]y = -4x^2 - 8\\y = -4(2)^2 - 8\\y = -4(4) - 8\\y = -16 - 8\\y = -24[/tex]

Output (y) is 24

Answer:

The first one

Step-by-step explanation:

4x - 3y = 15  .first you subtract the 4x from both sides to get it in correct form

-3y = -4x + 15 . Then you divide both sides by -3 to isolate the y

y = 4/3x - 5  . Then you are left with this answer

Answer:

y = 4/3x - 5 (first answer on your photo)

Step-by-step explanation:

4x - 3y = 15

4x - 3y = 15 (we use -4x)

-3y = 15 - 4x (divide by -3)

y = 4/3x - 5

Answer:

y = -3x +11

Step-by-step explanation:

notice how on the y column the values go down by three, meaning that the slope is -3

to find the y-intercept, look at the x column and find 0 and its corresponding y value

Answer:

Acute angles measure less than 90 degrees.

Answer:

I didn’t really encounter any difficulty in determining a polynomial. The issue was that numbers with negative exponents or those which had square roots in them aren’t referred to as polynomials.

The only minor issue was solving problems with numbers which had different exponents in them and needed some form of simplification.

Answer:

Step-by-step explanation:

7h-7h=0

We add all the numbers together, and all the variables

=0

h=0/1

h=0

Answer:

EF=35

EG=22

Step-by-step explanation:

EF

7y-14=2y+21

5y=35

y=7

EF=7(7)-14=49-14=35

EG

15x+7=12x+10

3x=3

x=1

EG=15(1)+7=15+7=22

Answer:

(a). 35 units ; (b). 44 units

Step-by-step explanation:

(a). 7y - 14 = 2y + 21 ⇒ y = 7

EF = 7(7) - 14 = 35 units

(b). EJ = JG

15x + 7 = 12x + 10 ⇒ x = 1

EG = 2 × (15(1) + 7) = 44 units

-12x+3y=24

(get y alone on the left)

3y=12x+24

(divide by 3)

y= 4x+8
