1: Ye all of them are terms except the “+”
2: 2a, 3b, and -4c are examples of terms
3: Terms they are examples of terms.
4: Answer:

2a, 3b and -4c are examples of terms.

Step-by-step explanation:

Given : Expression

To find : 2a, 3b and -4c are examples of ?

Solution :

We have given the expression

A term is made up of a constant multiplied by a variable.

In the given expression,

Variables are a, b and c.

Constant are 2,3 and -4.

So, 2a, 3b and -4c will make a term.

Therefore, 2a, 3b and -4c are examples of terms.

Answer:

Step-by-step explanation:

V = π times r^2 times h (height)

452.16 = 3.14 times r^2 times 4

Multiply 3.14 times 4

452.16 = 12.56 times r^2

Divide 452.16 by 12.56.

452.16 / 12.56 = 36

36 = r^2

The square root of 36 is 6.

So the radius of the cylinder is 6 yards^3.

Answer:

x = 13.6 in

Step-by-step explanation:

The arc x is calculated as

x = circumference of circle × fraction of circle

   = 2πr × [tex]\frac{0.8}{2\pi }[/tex] ( cancel the 2π on numerator/ denominator )

   = 17 × 0.8

   = 13.6 in

Answer: 675ft

Step-by-step explanation: 614 + 61 (since it’s below sea level) =675ft

Answer:

c) x=1.23

Step-by-step explanation:

a =3

b=2

c=-7

use quadratic equation where

[tex] { ax}^{2} + bx + c = 0 = \frac{ - b \: + or \: - \sqrt{ {b} ^{2} - 4ac} }{2a} [/tex]

-2+/- square root of (2^2- (4×3×-7) ) all that over 2x3

square root of (2^2-(4×3×-7) )

= 9.38083152

2×3=6

-2+or - 9.38 all that divided by 6

-2+9.38= 7.38÷6

x=1.23

or

-2-9.38 all divided by 6

-2-9.38= -11.38 ÷6

x= -1.9

all in all x can't be negative meaning x=1.23

Answer: 4/3

Step-by-step explanation:

Answer:

-4/3

Step-by-step explanation:

-4/3 Use rise over run. The line went down 4 (hence the negative) and then went over 3. Slope intercept form is -4/3x + 2 or -1.3x + 2. Depending on what they are looking for.

Answer:

6, but the question makes more sense when asking about 12.5% from 48

Step-by-step explanation:

to get a percentage of something, we just have to remember that [tex]X\% = \frac{X}{100}[/tex] and that we just need to multiply.

Yes, percentages are just numbers, but the percentage sign lets us signify the purpose of a number.

48 * 12.5% = 48 * 0.125 = 48 / 8 = 6

x bars <4> and y bars come in <3>

Answer:

5(4x + 3y) = 20x + 15y

Step-by-step explanation:

The matter of months in which in this case is 5 months is the coefficient.

The amount of boxes per month is important information. We don't know how many bars are in each box. EACH is a key word for multiplying. If we want to know quickly how many bars are in 4 boxes (or 3) of the granola bars. We can simply multiply the amount of bars for each box with the amount of boxes. Since we don't know the amount  of bars there are in each box we are going to use a variable. so it would look like this- 4x + 3y BUT we need to add the coefficient. Now rewrite the expression. 5(4x + 3y)

We can use the distributive property to generate an equal expression.

Answer:

Jump discontinuity at x = -2 & infinite discontinuity at x = 0.

Step-by-step explanation:

Hi again,

In this example, we see that there is a jump discontinuity at x = -2 because the line hypothetically "jumps" from y = 2 to y = 0. (just a way to remember these terms)

In addition, there is an infinite discontinuity at x = 0 because the green function will become infinitely close to x = 0 but never crosses nor touches it.

Hope this explanation was helpful. Cheers.

Answer:

(-16,2)

Step-by-step explanation:

x= −8y

−x+y= 18

substitute for x:

-(-8y) + y = 18

8y + y = 18

9y = 18

divide both sides by 9:

y = 2

x = -8(2) = -16

Answer:

x= 48

exterior angle theorem

-12+48 = 36

[tex]x=30\\[/tex]

Step-by-step explanation:

Answer:

x = 30

Step-by-step explanation:

[tex]\frac{45}{27} = 1.67\\[/tex]

1.67 x 18 = 30.06

round to the nearest whoeo number = 30

Answer:

Step-by-step explanation:

The rate of change, m, is defined as

m=(y2-y1)/(x2-x1), in this case we have points (-15,-3) and (-7,-1) so

m=(-1+3)/(-7+15)

m=2/8

m=1/4

Answer:

y = 1/2 x + 5

Step-by-step explanation:

slope (m) = (y'-y) / (x'-x)

(y-6)/(x-2) = 1/2

y - 6 = 1/2 x - 1

y = 1/2 x + 5

1) Option 3

2) Option 3

3) Option 3

4) Option 1

5) Option 2

6) Option 3

7) Option 1

Step-by-step explanation:

1) [tex]y = x^2 + 4x + 3[/tex]

Lets split the middle term.

[tex]=> y = x^2 + 3x + x + 3[/tex]

[tex]=> y = x(x+3) + 1(x + 3)[/tex]

[tex]=> y = (x+1)(x+3)[/tex]

∴ [tex]x = -3 , -1[/tex]

2) [tex]y = 8x^2 - 22x + 5[/tex]

Lets split the middle term.

[tex]=> y = 8x^2 - 20x - 2x + 5[/tex]

[tex]=> y = 4x(2x - 5) - 1(2x - 5)[/tex]

[tex]=> y = (2x - 5)(4x - 1)[/tex]

∴ [tex]x =\frac{1}{4} , \frac{5}{2}[/tex]

3) [tex]y = x^2 - 5x[/tex]

[tex]=> y = x(x - 5)[/tex]

∴ [tex]x = 0 , 5[/tex]

4) [tex]y = 12x^2 + 18x[/tex]

[tex]=> y = 6x(2x + 3)[/tex]

∴ [tex]x = \frac{-3}{2} , 0[/tex]

5) [tex]y = x^2 - 7x + 12[/tex]

Lets split the middle term.

[tex]=> y = x^2 -3x - 4x + 12[/tex]

[tex]=> y = x(x - 3) - 4(x - 3)[/tex]

[tex]=> y = (x - 3)(x - 4)[/tex]

∴ [tex]x = 3,4[/tex]

6) [tex]y = 3x^2 + 10x + 8[/tex]

Lets split the middle term.

[tex]=> y = 3x^2 + 6x + 4x + 8[/tex]

[tex]=> y = 3x(x + 2) + 4(x + 2)[/tex]

[tex]=> y = (x + 2)(3x + 4)[/tex]

∴ [tex]x = -2 , \frac{-4}{3}[/tex]

7) [tex]y = x^2 - 4x - 45[/tex]

Lets split the middle term.

[tex]=> y = x^2 - 9x + 5x - 45[/tex]

[tex]=> y = x(x - 9) + 5(x - 9)[/tex]

[tex]=> y = (x - 9)(x + 5)[/tex]

∴ [tex]x = -5 , 9[/tex]

Answer:

f(1) = -4

Step-by-step explanation:

Given that,

f(x) = 2x-6

We need to find the value of f(1).

Put x = 1 in the above expression.

f(1) = 2(1)-6

= 2-6

= -4

So, the value of f(1) is equal to -4.

Step-by-step explanation:

We have -4x > -10, so 4x < 10

Answer:

A. x < 2.5

Step-by-step explanation:

you subtract 5 on both sides

then you get -4x > -10.

then you divide -4 on both sides

and you get x<2.5
