What is the slope of the line 3x-7y=11

2 answers:

8 0

Slope intercept form is y=mx+b where m=slope and b=yintercept so

3x-7y=11
add 7y to both sideds
3x=11+7y
subtract 11 from both sides
3x-11=7y
divide both sides by 7
3/7x-11/7=y
y=3/7x-11/7

slope is 3/7

You could change the equation to slope intercept form:
3x - 7y = 11
-7y = 11 - 3x
y = (11 - 3x)/-7
y = 3/7 x - 11/7
The slope would be 3/7

Which can also be found by using -A/B, A being 3 and B being -7

Answer:

x always comes first so that is 0

then it is y and that is -6 so the answer is (0,-6) aka B

What is the ordered pair or real numbers for which x + y = 99 and x^2 - y^2 = 99.

skad [1K]

Given : x + y = 99 ------------ [1]

Given : x² - y² = 99

We know that : (x² - y²) = (x + y)(x - y)

⇒ (x + y)(x - y) = 99

⇒ 99(x - y) = 99

⇒ x - y = 1 ------------- [2]

Adding Equation [1] and [2], we get :

⇒ (x + y) + (x - y) = 99 + 1

⇒ 2x = 100

⇒ x = 50

Substituting x = 50 in Equation [1], we get :

⇒ 50 + y = 99

⇒ y = 99 - 50

⇒ y = 49

So, The Ordered pair (x , y) = (50 , 49)

F(x)=x² what is g(x)

sergiy2304 [10]

Answer:

C) $g(x) = -x^2 - 3$

Step-by-step explanation:

The function has been reflected in the x-axis, so -f(x)

then translated by 3 units down, so -f(x) - 3

Therefore, $g(x) = -x^2 - 3$
