3x-2y=-7
2x+5y+=8

Answers

Answer 1

Answer: 3x-2y=-7=  Slope = 3.000/2.000 = 1.500

 x-intercept = -7/3 = -2.33333

 y-intercept = 7/2 = 3.50000

2x+5y+=8

 Slope = -0.800/2.000 = -0.400

 x-intercept = 8/2 = 4

 y-intercept = 8/5 = 1.60000

5a+8+(-2a)=-7
I need help with this question especially because of the parenthesis

Answers

Answer:

5a+8+(-2a)=-7

5a+8-2a=-7

5a-2a=-7-8

3a=-15

3a/3=-15/3

a=-5

Answer:

a = -5

Step-by-step explanation:

Simplify both sides:

5a + 8 + (-2a) = -7

(5a + -2a) + 8 = -7

3a + 8 = -7

Start solving for a by subtracting 8 from both sides

3a+8-8 = -7 - 8

3a = -15

Next, divide both sides by 3

3a/3 = 1

-15/3 = -5

a = -5

D.
y+5 = (– 2)

Answers

y-5=m(x+2) is the answer in point slope form

Answer:

it actually y=1/3x+17/3

Step-by-step explanation:

First of all, remember what the equation of a line is:

y = mx+b

Where:

m is the slope, and

b is the y-intercept

To start, you know what m is; it's just the slope, which you said was 1/3. So you can right away fill in the equation for a line somewhat to read:

y=1/3x+b.

Now, what about b, the y-intercept?

To find b, think about what your (x,y) point means:

(-2,5). When x of the line is -2, y of the line must be 5.

Because you said the line passes through this point, right?

Now, look at our line's equation so far: . b is what we want, the 1/3 is already set and x and y are just two "free variables" sitting there. We can plug anything we want in for x and y here, but we want the equation for the line that specfically passes through the the point (-2,5).

So, why not plug in for x the number -2 and for y the number 5? This will allow us to solve for b for the particular line that passes through the point you gave!.

(-2,5). y=mx+b or 5=1/3 × -2+b, or solving for b: b=5-(1/3)(-2). b=17/3.

The equation of the line that passes through the point (-2,5) with a slope of 1/3

is

y=1/3x+17/3

Which diagram provides a counter example to the statement below?

“Supplementary angles are never congruent.”


Answers

Two or more angles are supplementary if and only if they can add up to [tex]180^{o}[/tex].  Thus, the appropriate option would be C.

Supplementary angles are angles that add up to the value of angle on a straight line i.e [tex]180^{o}[/tex].

Congruent property of angles implies that they have equal value.

Thus, the given statement that: “Supplementary angles are never congruent”, implies that they can not be equal in value. Thus the contrary to the statement would be: “Supplementary angles are sometimes congruent.”

Considering the figures given in the question, the counter example to the given statement is the figure in option C. [tex]180^{o}[/tex]. Because angle 1 and 2 are approximately equal.

D.

Answers

D, slope=3x and y-intercept =-2

The slope of the line is - 3 and the y - intercept of the line is - 2.

What is Equation of line?

The equation of line passing through the points (x₁ , y₁) and (x₂, y₂) with slope m is defined as;

y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Given that;

The equation of line is,

⇒ y = - 3x - 2

We know that;

The slope - intercept form of the equation of line is,

⇒ y = mx + b

Where, m is slope and b is y - intercept.

So, By comparing we get;

The slope (m) of the line = - 3

And, the y - intercept of the line = - 2.

Which particle is used as a beam to treat cancer? electron neutron proton Background Halloween is typically the perfect holiday for young people. Its full of mischief, goofing around and candy galore. But this year, the annual October 31 festivities will probably look quite a bit different thanks to corona. Social distancing precautions will force many to alter their Halloween traditions in 2020. But that doesnt mean they wont find new ways to keep it spooky. The Centers for Disease Control and Prevention (CDC) released a list of classic Halloween activities ranked by risk levels. The agency says classic, door-to-door trick-or-treating is a high-risk activity during the pandemic. As an alternative, the agency suggests hosting a scavenger hunt-style trick-or-treat search around the house. If you do still plan to go venture out to collect candy, The Washington Post recommends taking precautions. Its recommendations include: using hand sanitizer frequently, avoiding gathering in groups and not eating candy while trick-or-treating. Also, make sure your costume includes a cloth mask. Your average costume mask might not offer the same protection against the corona virus, the CDC warns. Haunted attractions have been forced to adapt to the scary realities of 2020, as well. Salt Lake Citys Fear Factory haunted house is usually an up-close-and-personal experience. It features terrifying actors who swoop in close for a scare. This year, it will offer socially distanced frights. The scare has been completely redesigned, says Fear Factory COO Rob Dun field. We used to have animations draw customers attention so actors could pop out and startle them up close. Now, thats reversed. The costumed actors draw attention from farther away, then trigger an animation, loud noise, or air blast to go off right next to a person. In addition, drive-through haunted houses are popping up in cities around the world, including San Diego, Orlando, Houston and Tokyo. Every year has its costume trends, and 2020 will be no different. Undoubtedly, there will be many corona-themed costumes. But costume companies like Party City have also seen a jump in nurse, doctor and firefighter costumes. I think people are turning to the people who helped during the pandemic every day, says Julie Roehm, Party Citys chief marketing and experience officer. If you want a more low key and spook-free Halloween, you still have plenty of options. Sam Dominguez, a pediatrician specializing in infectious diseases, says that small groups of friends can gather outside to carve pumpkins or watch Halloween movies. But they should still wear masks and stay socially distanced. Thankfully, Halloween revelers will be able to depend on candy. This year, candy companies are preparing to sell more treats online. They are also focusing on candy that can be eaten at home, rather than passed out to trick-or-tr eaters. Already, supermarket analysts say the sale of chocolate and candy is up 13 percent from 2019. Everyones been cooped up in the house, so people are looking for something to celebrate, says Katie Thomas, a consumer trends analyst at the Barney Consumer Institute.
