Solve for x.

-15 = 22x + 7

Answers

Answer 1
Answer: we transport 7 to the other side and it changes sign and be -7
-15-7=22x
-22=22x
we divide both side by 22
therefore x=-1

What conic section does the equation x2 + y2 – 4y – 1 = 0 represent?ellipse

hyperbola

circle

parabola

Answers

The conic section that the above equation represents is a CIRCLE.

Use completing the square for y and put the equation in standard form: 
x²+ y² - 4y + [(-4)/2]² - 1 = 0 + [(-4)/2]²
x² + y² - 4y + (-2)² - 1 = 0 + (-2)²
x² + y² - 4y + 4 - 1 = 4 
x² + (y - 2)² - 1 = 4 
x² + (y - 2)² = 4 + 1
x² + (y -2)² = 5

The radius of the circle is the square root of 5. Its center is found at (0,2)

Which table corresponds to the function y=-3x+5

Answers

If you want to draw a table, you need to give values to the X and resolve the equation to find Y.

For example with y=-3x+5

X=0

Y= -3 x 0 + 5

Y= 5

X=1

Y = -3x1 + 5

Y=2

X=2

Y= -3 x 2 + 5

Y= -1

Whe you have some numbers, draw an X Y axis and you can graphic it.

The train at the amusement park is a scale model of a full-size train. A measure of 0.15 meter on the train at the amusement park represents 1 meter on the full-size train. The train at the amusment park is 21 meters long. What is the length of the full-size train in meters

Answers

Answer:

The length of the full-size train is 140 meters.

Step-by-step explanation:

To determine the length of the full-size train, we will use the given relationship between the train at the amusement park and the full-size train.

From the question,

0.15 meter on the train at the amusement park represents 1 meter on the full-size train,

Let the length of the full-size train be x

Now,

If 0.15 meter on the train at the amusement park represents 1 meter on the full-size train

Then, 21 meters on the train at the amusement park will represent x meters on the full-size train

0.15 × x = 21 × 1

0.15x = 21

x = 21/0.15

x = 140 meters

Hence, the length of the full-size train is 140 meters.

Answer:

140m

Step-by-step explanation:

0.15 × x = 21 × 1

0.15x = 21

x = 21/0.15

x = 140 meters

Given the parent functions f(x) = log3 (5x − 5) and g(x) = log3 (x − 1), what is f(x) − g(x)?. . a. f(x) − g(x) = log3 (4x − 4). b.f(x) − g(x) = log3 (4x − 6). c. f(x) − g(x) = log3 5. d. f(x) − g(x) = = log3 1/5.

Answers

f ( x ) = log _(3) ( 5 x - 5 ), g ( x ) =log _(3) ( x - 1 ); \n f ( x ) - g ( x ) = log _(3)( 5 x - 5 ) - log _(3)( x - 1 ) = \n log _(3) (5(x-1))/(x-1) = log _(3) 5
Answer: C ) f ( x ) - g ( x ) = log3 5

What is the square 16/15 in simplest radical form?

Answers

Answer:

To start off, this fraction needs to be rationalized; you can't have a radical in the denominator. So, you multiply both the numerator & denominator by the same number (so as to not mess up the proportion of numerator:denominator; it's like multiplying by 1) & get the radical out of the denominator. What number would that be? sqrt5.

So we have (sqrt6/sqrt5)•(sqrt5/sqrt5).

To simplify that, we get (sqrt6•sqrt5)/(sqrt5•sqrt5).

This can be rewritten as:

sqrt(6•5)/sqrt(5•5)

= sqrt30/sqrt25

Now, sqrt25 = 5, so that problem is solved as such:

sqrt30/5

I'm thinking sqrt30 can't be simplified any further. If it can, do so.

Hope this helps!
