Answer:
∆QRS is an obtuse triangle
Step-by-step explanation:
[tex]x + 2x + 8x - 40 = 180 \\ 11x = 220 \\ x = 20[/tex]
[tex] < q = 20 \\ < r = 8(20) - 40 = 120 \\ < s = 2(20) = 40[/tex]
<R = 120° > 90° which makes this an obtuse triangle
Use long division to divide and use the result to factor the dividend completely.
(5x2-13x - 28) + (x – 4)
(5x² - 13x -28)/(x-4) = (x-4)(5x+7) so x = -7/5 and x = 4 are the two factors of the given polynomial.
What is a factor of a polynomial ?The factors of a polynomial are those values of x for which the given polynomial satisfies.
According to the given question we have to divide a polynomial (5x² - 13x -28) by (x - 4).
(5x² - 13x -28)/(x-4) = (x-4)(5x) + (7x - 28).
(5x² - 13x -28)/(x-4) = (x-4)(5x+7).
So, the obtained factor is (5x+7) = 0.
∴ 5x + 7 = 0
5x = -7
x = -7/5 is a factor of the given polynomial and by substituting these value in x.
(5x² - 13x -28)
5(-7/5)² - 13(-7/5) - 28 = 0
5(49/25) + 91/5 - 28 = 0
49/5 + 91/5 - 28 = 0
140/5 - 28 = 0.
28 - 28 = 0
0 = 0 ( hence satisfied that -7/5 is a factor of the given polynomial ).

Step-by-step explanation:
which is an equation of the line with a slope of 1/4 and a y-intercept of -2?
Answer:
y = 1/4x -2
Step-by-step explanation:
If the slope is 1/4, then you must multiply x by 1/4. If we plug 0 into 1/4x, we get 0, but we need -2, so we must subtract 2 in the equation.

x-intercept 1; y-intercept = 2
Answer:
[tex]y = 2x + 2[/tex]
Step-by-step explanation:
The equation of any (non-vertical) line can take the form
y = ax + b where a is the slope and b is the y intercept. We know that in this case, the y intercept is 2. So we can substitute b = 2:
[tex]y = ax + 2.[/tex]
Now, to find the x intercept, simply put y = 0 (since every point on the x axis has y = 0) and x = -1, since that is the given x intercept:
0 = -a + 2, so we see that a = 2. The equation is then:
y = 2x + 2

Amelie has three dogs, Max, Jasmine, And Springer. She buys a bag of dog food that contains a special mix.

I will give BRAINLIEST to the person that solves this.
If Max gets 1/4 of the bag, Jasmine gets 1/3 of the bag then Springer gets 5/12 of the bag of dog food.
What is Fraction?A fraction represents a part of a whole.
Given that Amelie has three dogs, Max, Jasmine, And Springer.
Max gets 1/4 of the bag, Jasmine gets 1/3 of the bag, and Springer gets the rest.
We have to find the fraction of the bag dose Springer get
Let's first add up the portions of food that Max and Jasmine get.
Max's portion = 1/4
Jasmine's portion = 1/3
The total of their portions is:
1/4 + 1/3 = 3/12 + 4/12 = 7/12
This means that Springer gets the remaining portion of the bag:
1 - 7/12 = 5/12
Therefore, Springer gets 5/12 of the bag of dog food.

Answer:
x=6
Step-by-step explanation:
Step 1: Cross-multiply.
x−3 / 5 = 6 /10
(x−3)*(10)=(6)*(5)
10x−30=30
Step 2: Add 30 to both sides.
10x−30+30=30+30
10x=60
Step 3: Divide both sides by 10.
10x 10 = 60 10

The location of the vertex Q after the dilation is (-2,-2). What is the location of vertex M after the dilation?
The location of vertex M after the dilation by a factor of 1/4 is at (-4, 3)
Dilation is a way of moving an object from a point on a plane to another location.
From the diagram attached, the coordinate of the vertex Q is at (-8, -8).
If the vertex Q after the dilation is (-2,-2), this means that the original coordinate is dilated by a factor of 1/4.
The vertex of coordinate M from the diagram is (-16, 12). Dilating the coordinate using a scale factor of 1/4 will give;
M' = (-16/4, 12/4) = (-4, 3)
Hence the location of vertex M after the dilation is at (-4, 3)

find the sum of the even integers from 20 to 50.
with solutions please help
Answer: 560
Step-by-step explanation:
There are [20, 22, 24, 26, 28]: 5 even integers for each ten numbers.
The 20's set can be written as 5*20 + (2+4 + 6 + 8) = 5*20 + (20) = 120
The 30's can be written: 5*30 + 20 = 170
40's: 5*40+20 = 220
50's: 5*50+20 = 270
60's: 5*60+20 = 320
Each set is incremented by 50
We want the sets for 20, 30, and 40, plus the number 50.
(120+170+220+50) = 560
You can also do this in Excel (attached). Set the first cell to 20, the next cell below equal to the cell above plus 2. Then draw the second cell down until you've reached 50. Then sum the cells to arrive at 560.

This is an equilateral triangle.
We see that all 3 angles are equal, so all sides are equal also.
So 2x - 6 = 10
2x = 16
x = 8.
Answer:
Step-by-step explanation:
If I am correct the triangle has equal sides and I think you're trying to find x. So 10=2x-6 and then solve. Once you get the x (assuming you know how to get it) plug it into the equation (of 2x-6) and get the remaining number. (For example: if x=2 then 2x2-6, then you solve: 2x2=4 4-6=-2) I don't know if you want the answer though...
(depends if you want x or the rest)

Twice a quantity usually indicates to take two of the things in question; usually this indicates to multiply by 2. Thus "twice a number x" can be written symbolically as 2x. If this is part of a problem, say twice a number x is 6, then we can rewrite algebraically as 2x=6; dividing both sides by 2 yields x=3.
