Answer:

Option 1 - $y=-5x+12$

Step-by-step explanation:

Given : A given line has the equation $10x+2y=-2$

To find : What is the equation, in slope-intercept form, of the line that is parallel to the given line and passes through the point (0, 12)?

Solution :

The slope intercept form is $y=mx+c$

where, m is the slope and c is the y-intercept.

Writing given equation in slope intercept form,

Equation $10x+2y=-2$

Take x to another side,

$2y=-10x-2$

Divide both side by 2,

$y=-5x-1$

The slope intercept form of the equation is $y=-5x-1$

Where, m=-5 is the slope and c=-1 is the y-intercept.

When two lines are parallel their slopes are equal i.e. $m_1=m_2$

Let the equation be $y=mx+c$

As lines are parallel then m=-5

We have given lines passes through point (0,12).

Substitute in equation,

$12=-5(0)+c$

$c=12$

Substitute back in equation,

$y=-5x+12$

Therefore, The required equation is $y=-5x+12$

So, Option 1 is correct.

Lisa says that the indicated angles cannot have the same measure. Marita disagrees and says she can prove that they can have the

AlexFokin [52]

I agree with Marita, that the angles could have the same measure. This can be proven if you set the two amounts equal and solve for x.

9x - 25 + x = x + 50 + 2x - 12

To begin, we should combine like terms on both sides of the equation to start simplifying the equation.

10x - 25 = 3x + 38

Next, we should subtract 3x from both sides and add 25 to both sides to get the variable x alone on the left side of the equation.

7x = 63

Finally, we should divide both sides by 7, to get rid of the coefficient of x.

x = 9

If you plug in 9 for x in our first equation, you get that both of the angle measurements equal 65 degrees. This means that Marita is correct, because if x = 9, then the angles would have the same measure.

Why is customer awareness a synonym of customer responsibility?

LUCKY_DIMON [66]

Customer awareness is the same as customer responsibility. this is because a customer should always be aware of any deals, defectives, or flaws in the product. being “aware” means “having knowledge of a situation”. being aware of your purchases affects your responsibility and attentiveness. customers should always examine the closely before purchasing.

Ariel left her home at 9 a.m., driving at 45 mph. At 11 a.m. her brother left the home and started after her at 60 mph. At what

Nana76 [90]

Answer:

Her brother catch her at 11 am + 4hour = 15 p.m

Step-by-step explanation:

Given as ;

Speed of Ariel = 45 mph

She left home at 9 a.m

Her brother speed = 60 mph

Her brother left home at 11 a.m

Now from question So As Ariel speed is 45 mph so, after two hours pass , she ahead 90 m .

As her brother travel as 60 mph ,so he travel at ( 60 - 45 )= 15 mph faster

So, with this speed her brother will catch up her at $\frac{90}{15}$ = after 4 hour .

Hence her brother catch her at 11 am + 4hour = 15 p.m Answer

A hovercraft takes off from a platform. Its height (in meters), xxx seconds after takeoff, is modeled by: h(x)=-2x^2+20x+48h(x)=

Ad libitum [116K]

the maximum height is the y-value of the vertex.

h(x) = -2x² + 20x + 48

$x = \frac{-b}{2a} = \frac{-20}{2(-2)} = \frac{-20}{-4} = 5$

h(5) = -2(5)² + 20(5) + 48

= -50 + 100 + 48

= 50 + 48

= 98

Answer: 98 meters
