Answer:

Step-by-step explanation:

I am not completely sure.

if x=4 then it would be 12

if x=6 then it would be 18

if x=9 then it would be 27

if x=10 then it would be 30

the side is shorter than 19 but definitely longer than 6. To me, it looks like a little more than double, more of triple and 6 times 3 is 18.

Eight more than the product of a number and six equals three

mixas84 [53]

Answer:

8x + 6 = 3

Step-by-step explanation if solving for x

Simplifying

8x + 6 = 3

Reorder the terms:

6 + 8x = 3

Solving

6 + 8x = 3

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-6' to each side of the equation.

6 + -6 + 8x = 3 + -6

Combine like terms: 6 + -6 = 0

0 + 8x = 3 + -6

8x = 3 + -6

Combine like terms: 3 + -6 = -3

8x = -3

Divide each side by '8'.

x = -0.375

Simplifying

x = -0.375

Question 1 Simplify the following expression: (5x2 + 3x + 4) − (2x2 − 6x + 3). If the final answer is written in the form Ax2 + Bx + C, what is the value of B?
Solution:
5x^2 + 3x + 4 - 2x^2 + 6x - 3 = 3x^2 + 9x + 1
Then, B = 9 Hope this helped=)

I need help on number 16 these instructions say to solve these equations by cross multiplying

Grace [21]

Answer:

15. x = 4

16. a = 19

Step-by-step explanation:

"Cross multiply" essentially means "multiply both sides of the equation by the product of the denominators."

$\dfrac{x}{6}=\dfrac{2}{3}\\\\3(x)=6(2)\qquad\text{"cross multiply"}\\\\\boxed{x=4}\qquad\text{divide by 3}$

This is an example of a problem in which cross-multiplying introduces the need for an extra step: divide by 3. Had we simply multiplied by the denominator of the x-term, we would have been finished in one step:

x = 6(2/3) = 4

That is, rather than multiplying by the <em>product of the denominators</em>, sometimes the problem can be solved more easily if you multiply by their <em>least common multiple</em>.

$\dfrac{a+1}{a+5}=\dfrac{a-4}{a-1}\\\\(a-1)(a+1)=(a+5)(a-4)\qquad\text{"cross multiply"}\\\\a^2-1=a^2+a-20\qquad\text{simplify}\\\\\boxed{19=a}\qquad\text{add $20-a^2$}$

The equation y-3=-2(x+5) is written in point-slope form. What is the y-intercept of the line?

babunello [35]

Answer:

Step-by-step explanation:

y-intercept is the y-value when x = 0

y - 3 = -2(0 + 5)

y - 3 = -2(5)

y = -7
