Answer:
702 & 388
Step-by-step explanation:
let no =x&y
x-y=314
x+y/2=545
cross
x+y=1090
y=x-314
x+x=1090+314
2x=1404
x=702
y=702-314
=388

Find the slope.
Answer:
4/3 or 1 1/3
Step-by-step explanation:
Answer:
4/3 or 1and1/3
Step-by-step explanation:
To find the slope, all we need to do is plug in both coordinates into the slope formula and the result will be the slope.
the slope formula is [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1}}[/tex]
to make it easier, we can label each x and y as x2, x1, y2, and y1 (it really doesn't matter which y or x value is the one as long as they are from the same pair like (4,3) can be x1 and y1 but can't be x2 and y1)
(4,3) (x1,y1) (1,-1) (x2,y2)
so just plug it into the formula and solve:
[tex]m=\frac{-1-3}{1-4} =\frac{-4}{-3} =\frac{4}{3} or 1\frac{1}{3}[/tex]
A company makes a beverage that must have 12% real-juice content. How many gallons of beverage with 9% real-juice content must be mixed with 3000 gallons of beverage with 15% real-juice content to achieve the desired 12% real-juice content?
first lets change this problem into an equation...
0.09*x+0.15*3000=0.12(x+3000)
Step 1: Simplify both sides of the equation.
0.09x+(0.15)(3000)=0.12(x+3000)
0.09x+(0.15)(3000)=(0.12)(x)+(0.12)(3000)
0.09x+450=0.12x+360
Step 2: Subtract 0.12x from both sides.
0.09x+450−0.12x=0.12x+360−0.12x
−0.03x+450=360
Step 3: Subtract 450 from both sides.
−0.03x+450−450=360−450
−0.03x=−90
Step 4: Divide both sides by -0.03.
-0.03x/-0.03=-90/0.03
x=3000Answer:

Write a linear function f with f(5)=-1 and f(0)=-5
Answer:
Step-by-step explanation:
i need help with this pls :)
[] 10x + 4
(5x) + (2x + 5) + (3x - 1)
5x + 2x + 3x + 5 - 1
10x + 4
[] 4x + 4
Bottom: (1/2) * (3x -1) = 1/2x - 1/2
Left side: (1/2) * (5x) = 5/2x
Right side: (1/2) * (2x+5) = x + 5/2
\/
Add them together:
(x + 5/2) + (5/2x) + (1/2x - 1/2)
x + 5/2x + 1/2x + 5/2 - 1/2
4x + 4

Hope this helps and is correct, have a nice day! :D

If the vertex of a parabola is (3,5), what is the symmetry
Answer:
axis of symmtery: x = 3 or h = 3
Step-by-step explanation:
The vertex (h, k) of a parabola is the point wherein the graph intersects the axis of symmetry—the imaginary straight line that bisects a parabola into two symmetrical parts, where x = h.
In the standard form of quadratic equation, y = ax² + bx + c, the equation of the axis of symmetry is: [tex]x = \frac{-b}{2a}[/tex].In the vertex form of the quadratic equation, y = a(x - h)² + k, the equation of the axis of symmetry is: [tex]h = \frac{-b}{2a}[/tex].Regardless of whether the quadratic equation is in standard or vertex form, the x-coordinate (h) of the vertex determines the axis of symmtetry, hence, x = h.
Therefore, given that the vertex of a parabola is at point (3, 5), then it means that the axis of symmetry occurs at x = 3 or h = 3.

State what additional information is required in order to know that the triangles are congruent for the reason given.
Answer:
Segment RW congruent to segment XY
Step-by-step explanation:
SAS means side-angle-side.
You are given two congruent angles, so you already have the angle you need for SAS.
By the reflexive property, side XW is congruent to itself, so now you have a side also.
You need another pair of sides, but the two sides must include the angle.
Answer: Segment RW congruent to segment XY

12 out of every 15 people in the United States preter eating at & restaurant
over cooking at home. If 400 people selected eating at a restaurant on the survey, how many people
took the survey?
15
B
er
son
total people
Answer:
500
Step-by-step explanation:
Out of every 15 people, there are 12 people who prefer eating at restaurants which means that 80% of people (12/15=.8) prefer eating out.
If 400 selected eating at restaurants in a survey, this accounts for 80% of the people that voted.
We can simplify this now to 20%=100 people because 80% is also four-fifths of 100% and the remaining one-fifth will equal 100 people. (400/4=100)
Since the remaining 20% is 100 people, we can do 400+100= 500 people that participated in the survey.
what is number 11. solve for x
Answer:
78° +78°+3x-12= 180 {being isosceles triangle and sum of 3angles of a triangle is 180°}
156+ 3x-12=180
144+3x=180
3x=180-144.
3x=36
[tex]x = \frac{36}{3} [/tex]
x=12
Determine the type of triangle down below
=======================================================
Explanation:
The triangle is scalene because all three sides are different in length. Also, the angles are all different which is another piece of evidence of this.
The triangle is a right triangle because of the 90 degree angle. Often the term "right angle" is used in place of "90 degree angle".
---------
Extra info (optional)
We can rule out anything with "obtuse" in it because obtuse triangles are only when one angle is larger than 90 degrees; which is not the case here.We can rule out anything with "acute" because this triangle doesn't have all its angles smaller than 90.The triangle is not equilateral since we'd need all three sides to be the same (and all three angles to be 60).The triangle isn't isosceles because it needs exactly two sides to be the same length.Which is larger?
2 or 1.9999999999999999999
Answer:
2 would technically be larger, but if you were to round 1.999 to the nearest tenth, you would get 2.
