Answer:
(-7,-3)
Step-by-step explanation:
step one) solve one equation for x.
y=-3x
-3x/-3=y/-3
x=(-y/3)
step two) plug in x for the other original problem.
y=x-4
y=(-y/3)-4
step three) solve for y.
y=(-y/3)-4
y+4=(-y/3)-4+4
3*(y+4)=(-y/3)*3
3y+12=-y
(3y+12)-3y=-y-3y
12/-4=-4y/-4
y=-3
step four) plug in -3 for y and solve for x.
y=x-4
-3=x+4
-3-4=x+4-4
-7=x

An architect created a scale model of what a college campus will look like once construction is finished. The scale for the model is 2 in. : 25 ft. The tallest building in the model is 10 intall. How tall is the actual building?
Answer: 125ft
Step-by-step explanation:
In the model, we have the relation:
2in = 25ft
This means that 2 inches in the model represent 25ft for the actual college campus.
Then, if the building is 10 inches tall in the model, we have:
How many groups of 2 inches we have in 10 inches?
10in/2in = 5
And we know that each one of these 2 inches represent 25ft, then 5 of them are 5 times 25 ft:
The height of the building is 5*25ft = 125ft

A.) acute scalene triangle
B.) right isosceles triangle
C.) equiangular equilateral triangle
D.) obtuse scalene triangle
Answer:
D.) obtuse scalene triangle
Step-by-step explanation:
acute triangle: 3 acute angles
right triangle: 1 right angle, 2 acute angles
obtuse triangle: 1 obtuse angle, 2 acute angles
scalene triangle: no congruent sides
isosceles triangle: 2 congruent sides
equilateral triangle: 3 congruent sides
The question is:
"What type of triangle has no congruent sides and one angle that has a measure greater than 90° but less than 180°?"
That means scalene and obtuse.
Answer: D.) obtuse scalene triangle
The triangle is an obtuse scalene triangle, the correct option is D.
What is a Triangle?A triangle is a polygon with three sides, angles and vertices.
The triangle is classified into various types on the basis of the angle and on the basis of the equality of the length of the sides,
When the measure of all the angles of a triangle is less than 90 degree, it is an acute angle triangle.
When the measure of one of the angle of a triangle is equal to 90 degree, it is a right angled triangle.
When the measure of one of the angle of a triangle is greater than 90 degree, it is called an obtuse angle triangle.
When the measure of all side is different, it is a scalene triangle.
When the two side of a triangle is equal, it is an isosceles triangle.
When all the sides of a triangle is equal, it is an equilateral triangle.
The condition given in the question is triangle has no congruent sides and one angle that has a measure greater than 90° but less than 180°, it is an obtuse scalene triangle.

Write the equation in slope-intercept form. Do not use any spaces. Make sure your answer looks like y=mx+b. Y + 6 = 3(x - 4) *
Answer:
y = 3x+ 18
Step-by-step explanation:
Given the expression y + 6 = 3(x-4), we are to express in the form y = mx+b
Open the bracket
y + 6 = 3(x-4)
y+6 = 3x-12
Collect the like terms;
y - 3x = -12 - 6
y - 3x = 18
y = 3x + 18
Hence the required equation in slope-intercept form is y = 3x+ 18

A stock has an expected return of 10.5 percent, a beta of 1.55, and the expected return on the market is 8.5 percent. What must the risk-free rate be? (Do not round intermediate calculations and enter your answer as a percent rounded to 2 decimal places, e.G., 32.16.)
Answer: 4.86%
Step-by-step explanation:
The Capital Asset Pricing Model can be used;
Return = Risk free rate + beta * ( market return - risk free rate)
10.5% = Rf + 1.55 * (8.5% - Rf)
10.5% = Rf + 0.13175 - 1.55Rf
10.5% - 0.13175 = -0.55Rf
-0.02675 = -0.55Rf
Rf = -0.02675/-0.55
= 0.0486
= 4.86%

Find the least whole number N so that 2020 + N is exactly divisible by 11.
2020 + N ≡ 0 (mod 11)
N ≡ -2020 (mod 11)
Notice that 2020 = 183 • 11 + 7, so
N ≡ -(183 • 11 + 7) (mod 11)
N ≡ -7 (mod 11)
N ≡ 4 (mod 11)
[tex]N=4[/tex]
Step-by-step explanation:
Given :
Whole Number = N
Number = 2020 + N
Solution :
Now through observtion,
[tex]\dfrac{2020+N}{11}=184[/tex] ----- (1)
We took 184 because when we multiply 184 by 11 we get the nearest number to 2020

Answer:
Step-by-step explanation:
From the given attachment to the question, the following can be deduced.
1. M is the midpoint of GH, given that M is the definition of midpoint.
2. GM ≅ MH, given that x = 2. So that,
GM = 5x = 5(2)
= 10
MH = 3x + 4 = 3(2) + 4
= 10
Thus, GM ≅ MH
3. GM = MH is the definition of congruence. This implies that they are similar.
4. 5x = 3x + 4, by substitution property of equality.
Since, x = 2 then;
5(2) = 3(2) + 4
10 - 10
5. 2x = 4, given that x = 2.
6. GH = GM + MH, by division property of equality.

Answer:
The correct expression for this would be:
4g + 2c = 300
Step-by-step explanation:
Since the console costs 300 for buying 4 games and 2 controllers, let's represent 4 games with 4g and 2 controllers with 2c.
This means 4g and 2c gives 300. Mathematical, this is written as

Daniel has a coupon for $1.44 off
name-brand flour that usually costs
$9.12. The store-brand flour costs $8.86.
How much will Daniel save by using his
coupon to buy the name-brand flour,
instead of buying the store-brand?
I’m mostly struggling with the problem steps part I can do the first parts but then the other steps I struggle with.
Answer:
Daniel will save $1.18
Step-by-step explanation:
First, find the cost of the name-brand flour with the coupon:
Subtract 1.44 from the original price of 9.12:
9.12 - 1.44
= 7.68
So, the price of the name-brand flour with the coupon is $7.68
Now, find how much he will save by finding the difference between this price and the price of the store brand flour:
8.86 - 7.68
= 1.18
So, Daniel will save $1.18
Ng Order of Operations George has $15. He would like to know if he has enough money to see a movie ($9.00) and buy a pretzel ($2.65), a drink ($1.35), and two veggie cups ($1.74 each). George incorrectly used this numerical expression to decide if he had enough money. 15 - 9 + 2.65 + 1.35 + 2(1.74) Use the order of operations to simplify this expression.
Answer:
No, George does not have enough money to buy everything.
The correct expression is:
15 - 9 - 2.65 - 1.35 - 2(1.74)
Step-by-step explanation:
Given that:
Money present with George initially = $15
Money required to see the movie = $9
Money required to buy a pretzel = $2.65
Money required to buy a drink = $1.35
Money required to buy 2 veggie cups = $2(1.74)
To find:
Whether there is enough money with George to complete all the tasks.
Solution:
First of all, let us calculate all the money required and then we can subtract all the money from the initial amount to find whether there is enough money present with George.
If the result is in positive, there is enough money with George.
Total money required for all the activities = $9 + $2.65 + $1.35 + $2(1.74) = $16.48
Expression = $15 - $16.48 = -$1.48
The result is negative, therefore there is not enough money.
The correct expression is:
15 - 9 - 2.65 - 1.35 - 2(1.74)

U is the midpoint of TV. TU = x2 + 2x – 2. UV = -x + 8. Find the
positive value of x.
Answer:
x = 2
Step-by-step explanation:
It is given that,
U is the midpoint of TV.
TU = x² + 2x – 2
UV = -x+8
We need to find a positive value of x.
For midpoint,
TU = UV
Putting values,
x² + 2x – 2 = -x+8
or
x² + 2x – 2+ x - 8= 0
x² +3x-10 = 0
x² +5x - 2x -10 = 0
x(x+5) -2(x+5) = 0
(x-2) (x+5) = 0
x = +2 and x = -5
Hence, the positive value of x is 2.
