I need help please i’ll even give u a brainliest i just need the correct answer

How many solutions does the equation -3a + 3a + 6 = 7

STALIN [3.7K]

No solution because -3a +3a is cancelled out and 6 does not equal 7

If f(x) = x2 − 81 and g(x) = x+9/x-9, find g(x) · f(x).

dexar [7]

Answer:

f(x) = x² - 81 = ( x+ 9)(x - 9) Difference of two squares

g(x) = x+9/x-9

g(x) . f(x) = x + 9/ x - 9 × (x+9)(x - 9)

= ( x + 9)(x +9)

= ( x + 9)²

= x² + 18x + 81

Hope this helps.

Which of these lines is perpendicular to the line y = 3x + 2?

Morgarella [4.7K]

Answer:

(c) $y=\frac{-1}{3}x+4$ will be perpendicular to the line y = 3x+2

Step-by-step explanation:

We have given the the equation of line as y = 3x+2

We know the equation of line as y = mx+c , here m is slope and c is intercept

On comparing with standard equation of line m = 3

We know that slope of perpendicular line is $=\frac{-1}{m}$

So the slope of the line which is perpendicular to y = 3x+2 will be $=\frac{-1}{3}$

Now (a) Line is given as $y=\frac{1}{3}x+3$ its slope is $\frac{1}{3}$ so it will be not perpendicular

(b) Line is given as $y=\frac{1}{3}x+2$ its slope is $\frac{1}{3}$ so it will be not perpendicular

(c) Line is given as $y=\frac{-1}{3}x+4$ its slope is $\frac{-1}{3}$ so it will be perpendicular to the line y = 3x+2

(d) Line is given as $y=3x+\frac{1}{2}$ its slope is 3 so it will not perpendicular to the line y = 3x+2

Please help me graph the point (7 ,4).

bija089 [108]

Answer:

See explanation

Step-by-step explanation:

From the attachment, the question has been answered. However, the explanation is as follows;

Given that

$(x,y) = (7,4)$

This means that

$x = 7$

$y = 4$

See attachment (1)

Step 1: Locate point 7 on the x axis

Step 2: Locate point 4 on the y axis

Trace these two points until they intersect.

The point at which they intersect, is the required point (7,4) --See attachment (2)

Not sure how to do this. (I'm aware this is wrong lol)

Bezzdna [24]

I think the answer is 80 degrees. Think about it like you're moving the chunk with 100 degrees already filled in, to the space where you're trying to find the amount since they're the same. Vertical angles are supplementary and are equal to 180. So, 100+x = 180. x would equal 80 degrees.
