Answer:

y=-9

Step-by-step explanation:

-10(9)-8y=-18

solving for y.

Answer:

All the options are equivalent except;

4 + y

Step-by-step explanation:

The question relates to the number of ways the operation of a multiplication operation can be represented algebra

1) The coefficient of a variable is a multiplier of the variable

Therefore;

4y = 4 × y

2) When given two numbers or variables in a mathematical expression that are separated by parenthesis, then it is an indication that the two numbers are meant to be multiplied

Therefore;

(4)(y) = 4 × y

3) The dot symbol, '·', placed between two numbers, a number and a variable or two variables, is a representation of multiplication of the two quantities

Therefore;

4·y = 4 × y

However, multiplication, and addition are different mathematical operations that produce different results when applied;

Therefore;

4 + y ≠ 4 × y.

Answer:

2x(5+13)

Step-by-step explanation:

add then multiply by 2

Answer:

to find perimeter

= 2(L+w)

= 2(5+13)

10+26

36

so the answer is 2×(5+13)

hope it's helpful ❤❤❤❤

Answer:

18 because

12% = money saved / total earned money * 100

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

1) first there are a few rules we need to know:

a) the sum of any two sides of a triangle is always larger than the 3rd side

b) the difference between any two sides of a triangle is always smaller than the 3rd side;

hence,

3+4=7

4-3=1

triangle 3,4,5 follows all the rules,

triangle 13,2,11:

11+2=13

the sum of any two sides must always be GREATER than the 3rd side-so this is not an option

triangle 10,4,5

5+4=9

9<10

not an option

To find the inverse, interchange the variables and solve for y

G^-1 (x) = square root x - 1, - square root x-1

Answer:40

Step-by-step explanation:

100+10+10=3x

3x=120

Divide both sides by 3

X=40

Answer:

40

Step-by-step explanation:

add 100+10+10 and divide it by 3

Answer:

86 its the same thing on both sides if im wrong then 90?

Step-by-step explanation:

Answer:

p(-2) = -11

p(0) = -3

p(5) = 17

Step-by-step explanation:

Step(i):-

Given that the polynomial function  p(x) = -3 +4x ..(i)

Given x =-2 , 0 and 5

put x =-2 in equation (i)

p(-2) = -3 +4(-2)

       = -3 -8

p(-2) = -11

Step(ii):-

put x =0 in equation (i)

p(0) = -3 +4(0)

       = -3 +0

p(0) = -3

Step(iii):-

put x = 5 in equation (i)

p(5) = -3 +4(5)

       = -3 +20

p(5) = 17

Answer:

5-a) The perimeter of the rectangle = 2(2x + 4x + 1,5) = 12x + 3

Step-by-step explanation:

Answer:

1. What is the y-intercept? y = 4

2. What is the maximum point? 4

3. What are the x-intercepts? (write the negative one first) x = -2 and x = 2

Step-by-step explanation:

In simple terms, the y-intercept is the part (s) where the graph hits the vertical line.

The maximum point is the highest point of the graph, coincidentally the maximum point on this graph is right on the y-intercept.

In simple terms, the x-intercept is the part (s) where the graph hits the horizontal line.

Answer:

Graph C

Step-by-step explanation:

Since p is less than negative 2, it would be going to the left.

The dot also is hollow because -2 is not included.

Answer:

(x, y) -----> (x + 3, y - 4)

Step-by-step explanation:

3 to the right means add 3 to x.

4 down means subtract 4 from y.

(x, y) -----> (x + 3, y - 4)

Answer:

[tex]CD = 12.6866616739cm[/tex]

[tex]CD \approx12.7cm[/tex]

Step-by-step explanation:

[tex]CB = a[/tex]

[tex]AB = b[/tex]

[tex]AC = c[/tex]

[tex] {c}^{2} = {a}^{2} + {b}^{2} [/tex]

[tex] {a}^{2} = {c}^{2} - {b}^{2} [/tex]

[tex]a = \sqrt{ {c}^{2} - {b}^{2} } [/tex]

[tex]a = \sqrt{ {12}^{2} - {6}^{2} } [/tex]

[tex]a = \sqrt{144 - 36} [/tex]

[tex]a = \sqrt{108} [/tex]

[tex]CB = \sqrt{108} [/tex]

[tex] \sin(D) = \frac{opposite}{hypotenuse} [/tex]

[tex] \sin(D) = \frac{CB}{CD} [/tex]

[tex] \sin(55) = \frac{ \sqrt{108} }{CD} [/tex]

[tex](CD) \sin(55) = \frac{ \sqrt{108} }{CD} (CD)[/tex]

[tex](CD) \sin(55) = \sqrt{108} [/tex]

[tex] \frac{(CD) \sin(55) }{ \sin(55) } = \frac{ \sqrt{108} }{ \sin(55) } [/tex]

[tex]CD = \frac{ \sqrt{108} }{ \sin(55) } [/tex]

[tex]CD = 12.6866616739cm[/tex]

[tex]CD \approx12.7cm[/tex]
