Answer:

Step-by-step explanation:

45x+6y=15

-x+18y = 11

let's use elimination, the other way is by substitution,  either way works but, it looks to me like elimination would be easy with the  'y'

3(45x+6y=15)

135x + 18y = 45 ( subtract  2nd eq.  from 1st )

-( -x+18y = 11 )

136x +0y =34

x = 34 /136

x = 1 /4

there is X

plug that back into either of the 1st or 2nd equations to solve for y

- 1/4 + 18 y = 11

18y = 11 1/4

18y = 45/4

y = 45/4 *  1/18

y = 45/ 72

the fractions seem  "difficult"  but that's just what the given problem finds

Answer:

[tex]y=2sin[\frac{\pi}{4}(x+3) ]-5[/tex]

Step-by-step explanation:

The standard form for a sinusoidal function is given by:

y = Asin[B(x - C)] + D

Where A is the amplitude of the sine wave, the period is 2π/B, C is the phase shift and D is the vertical displacement / translation

Given:

A = 2, D = -5 (down), C = -3 (left).

8 = 2π/B; B = π/4

Therefore:

[tex]y=2sin[\frac{\pi}{4}(x+3) ]-5[/tex]

Answer:

this question doesnt have a solution it makes no sense

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

The degrees of a triangle add up to 180.

Angle C is already 90 degrees therefore angle A + angle B = 90 degrees.

Angle A is equal to sinA=1/2.

sinA=1/2 is equal to 30 degrees if you press 2nd, sin (1/2) into the calculator. You may also know this if you have memorized the values of trig.

90-30=60.

That leaves you with 60 degrees for angle B.

Answer: y= mx+b form

Answer:

Answer:

( -1.5 , 1 )

Step-by-step explanation:

Hello There!

When dilating a point we divide or multiply the coordinates by whatever the scale factor is

Because the scale factor is 1/2 we just have to divide the coordinates of point B by 2

Preimage coordinates - ( -3 , 2 )

-3/2=-1.5 or -3/5

2/2=1

Dilated image coordinates ( -1.5 , 1 )

Answer:

8192

Answer:

[tex](2x - 1)(2x - 3)[/tex]

Step-by-step explanation:

1) Split the second term in 4x² - 8x + 3 into two terms.

[tex] {4x}^{2} - 2x - 6x + 3[/tex]

2) Factor out common terms in the first two terms, then in the last two terms.

[tex]2x(2x - 1) - 3(2x - 1)[/tex]

3) Factor out the common term 2x-1.

[tex](2x - 1)(2x - 3)[/tex]

Therefor, the answer is (2x - 1) (2x - 3).

Answer:

$5150

Step-by-step explanation:

Given data

Principal=$4000

Rate=5.75%

Time= 5 years

The expression for the balance on  simple interest is

A=P(1+rt)

substitute

A=4000(1+0.0575*5)

A=4000(1+0.2875)

A=4000X(1.2875)

A=$5150

Hence the  balance is $5150

Answer:

ok so S=soda C=chips and G=gum

Step-by-step explanation:

From the information,

s+3=c

(1/2)c=g

from this P=s+c+g

P=s+(s+3)+((s+3)/2)

P=5/2s+9/2

Answer:

It would take Lena 9 hours.

Step-by-step explanation:

Looking at the problem I can do 696/12 to get the number of miles per hour she is traveling which is 58. With this number, I can take 522/58 to get 9 hours.

Answer:

Step-by-step explanation:

Remark

The best way to do this is to set up a proportion. It can be done by using d = r * t twice, but a more direct way is to use the proportion.

Formula

distance1 / time1 = distance2 / time2

Givens

distance1 = 696 miles

time1 = 12 hours

distance2 = 522 miles

time2 = x

Solution

696/12 = 522/x       Cross multiply

696 * x = 522* 12    Combine the right

696 * x = 6264        Divide by 696

x = 6264/696

x = 9 miles
