Answer:

12. The quotient of a number and ten = n/6

13. The sum of a number and six = x + 6

14. The product of nine and five less than a number = n = 9*5

15. Four times a number, reduced by one = 4*n - 1

I may have some wrong answers so please check them. :l

12- n/12 (n divided by 12, n is your unknown number)
13- n + 6
14- 9(n-5) this is nine times n-5, n-5 HAS to be in parentheses!
15- (4 * N) -1

Let a, b, c, and d be real numbers with a, c 6= 0. Prove that the lines y = ax+b and y = cx + d have the same x-intercept if and

Monica [59]

Step-by-step explanation:

We have got the lines :

$y=ax+b\\y=cx+d$

Both lines intercept the x-axis in the point :

$I = (i_{1} ,i_{2})$

In all point from x-axis the y-component is equal to 0.

$I=(i_{1},o)$

We replace the I point in the lines equations:

$0=a(i_{1})+b \\0=c(i_{1})+d$

From the first equation :

$0=a(i_{1})+b \\-b=a(i_{1})\\i_{1}=\frac{-b}{a}$

From the second equation :

$0=c(i_{1})+d\\ -d=c(i_{1})\\i_{1}=\frac{-d}{c}$

Then $i_{1}=i_{1}$

Finally :

$\frac{-b}{a}=\frac{-d}{c} \\\frac{b}{a}=\frac{d}{c} \\ad=bc$

y = ax + b and y = cx + d have the same x-intercept ⇔ad=bc

Answer:

m∠H = 10°

Step-by-step explanation:

ΔFGH is an isosceles triangle. I made a diagram, so m∠F ≅ m∠H by B.A.T(base angle theorem). This is because an isosceles triangle have to congruent sides and angles.

Give an example of a system of linear equations that can be solved by first adding the equations to eliminate one variable.

telo118 [61]

f ( 7 ) = 2.4 ft

Step-by-step explanation:

Solution:-

- This is modeled using a geometric sequence function with initial height from which ball is dropped hi = 18 feet, and a decrease in height by 25% after each successive bounce :

f ( x ) = 18 (0.75)^x

Where, x e [ 0 , ∞ ) : The number of bounces.

f (x) : The maximum height after xth bounce.

- The maximum height reached by the ball after its 7th bounce. So, x = 7:

f ( 7 ) = 18 (0.75)^7

f ( 7 ) = 2.4027 ft

- To the nearest tenth:

f ( 7 ) = 2.4 ft

Answer:

x = -4, y = 8.

Step-by-step explanation:

Question 16.

8x + y = -24 ........(A)

-3x - 2y = -4 ........(B)

Multiply (A) by 2:

16x + 2y = -48 Adding this to equation (B):

13x = -52

x = -4

Substituting this value of x in Equation (A):

8(-4) + y = -24

y = -24 + 32 = 8.
