answer:
sum: 19 + 7 = 26
difference: 19 - 7 = 12
step-by-step explanation:
the sum of x and y is 26. in other words, x plus y equals 26 and can be written as equation a:
x + y = 26
the difference between x and y is 12. in other words, x minus y equals 12 and can be written as equation b:
x - y = 12
now solve equation b for x to get the revised equation b:
x - y = 12
x = 12 + y
then substitute x in equation a from the revised equation b and then solve for y:
x + y = 26
12 + y + y = 26
12 + 2y = 26
2y = 14
y = 7
now we know y is 7. this means that we can substitute y for 7 in equation a and solve for x:
x + y = 26
x + 7 = 26
X = 19
good luck :)
hopefully, this helps
have a great day !!

Points (-2, 4) and (-1,1) lie on the same line. Which of the following equations represents the line?
A. y - 1 = -}(x + 1)
B. y - 1 = -3(x + 1)
C. y - 1 = -}(x - 1)
D. y - 1 = -3(x - 1)
Answer:
A
Step-by-step explanation:
There are 2 ways you can do this. I'll show you one!
1. Find the Slope
a. use the slope formla: (y1-y2)/(x1-x2)
(4-1)/(-2-1)= 3/-3= -1
This eliminates both B and D, as their slopes are -3
2. Now analyze the last 2 equations
a. A goes through the ordered pair (-1, 1)
b. C goes through the ordered pair (1, 1)
The line we want goes through (-1, 1), so A is the correct answer!
[tex]y-1=-3(x+1)[/tex] equation represents the line.
What is point slope form?The point slope form is used to find the equation of the straight line which is inclined at a given angle to the x-axis and passes through a given point.
Given points
[tex](x_{1} ,y_{1} )[/tex] = (-1, 1)
[tex](x_{2} ,y_{2} )[/tex] = (-2, 4)
Using point slope form
We know that the equation of line passing through points [tex](x_{1} ,y_{1} )[/tex] and [tex](x_{2} ,y_{2} )[/tex] is
[tex]y-y_{1} =\frac{y_{2}-y_{1} }{x_{2}-x_{1} }( x-x_{1})[/tex]
Therefore equation of line passing through points (-1, 1) and (-2, 4) is
[tex]y-1=\frac{4-1}{-2+1}(x-(-1))[/tex]
[tex]y-1=\frac{3}{-1} (x+1)[/tex]
[tex]y-1=-3(x+1)[/tex]
Option B is correct.

Step-by-step explanation:
No links! Please help I dont have much more time please
Answer:
1: The one vertical from 104° is 104°
2:The one near the corner is 20°
3: The two angles right next to 104° are 76°
Step-by-step explanation:
1: Vertical angle are always equal to each other.
2: All sides of the triangle must equal 180° in all. If you add 56° + 104° it equals 160°. Now subtract 180° - 160°. You get 20°.
3: All straight angles equal 180° in all. So, if you subtract 180° from 104° you will get 76°. And again, these two angles are vertical so they will both be 76°.

A line that is parallel to the line y=3x-8 and passes through the point (-1,6)
The equation of the parallel line is...
Answer:
y = 3x + 9
Step-by-step explanation:
If the line is parallel, that means it will have the same slope. So, the line will also have a slope of 3.
Using y = mx + b, plug in the slope and given point, and solve for b:
y = mx + b
6 = 3(-1) + b
6 = -3 + b
9 = b
Plug in the slope and b into y = mx + b
y = 3x + 9
So, the equation of the parallel line is y = 3x + 9

Answer: 8 1/4 miles
Step-by-step explanation:
I think your question isn't well written and should be:
Nathan jogged 2 1/4 miles on Monday. On Wednesday, he jogged 3 1/3 miles and on Friday, he jogged 2 2/3 miles. How far did Nathan jog altogether?
This will be:
= 2 1/4 + 3 1/3 + 2 2/3
= 2 3/12 + 3 4/12 + 2 8/12
= 7 15/12
= 7 + 1 3/12
= 8 3/12
= 8 1/4 miles

Rewrite with only sin x and cos x.
sin 3x - cos x
Answer:
sin (3 x) - cos (x)=
= sin (2x + x) - cos (x)=
= sin 2x * cos x + cos 2 x * sin x - cos x = ( using additional formulas )
= 2 sin x cos² x + ( cos² x - sin² x ) sin x - cos x =
= 2 sin x cos² x + ( 1 - sin² x - sin² x ) sin x - cos x =
= 2 sin x cos² x + ( 1 - 2 sin² x ) sin x - cos x =
= 2 sin x cos² x + sin x - 2 sin³ x - cos x

A car is purchase at $20000.The value of the car depreciates at 12.5% a year. What will the value of the car be to the nearest cent after 11 years
Answer: $4603.82
Step-by-step explanation:
Given
The initial cost of a car is [tex]P=\$20,000[/tex]
The rate of depreciation is [tex]i=12.5\%[/tex]
Depreciated value after n years is given by
[tex]\Rightarrow P(1-\frac{i}{100})^n\quad \text{where n=no. of years}[/tex]
Value after 11 years
[tex]\Rightarrow 20,000(1-\frac{12.5}{100})^{11}\\\\\Rightarrow 20000(0.875)^{11}=\$4603.82[/tex]

Answer:
67
Step-by-step explanation:
Use the triangle angle sum theorem. All interior angles of a triangle sum to 180 degrees. Angle b = 23, angle c = 90 (notice the marking in the triangle), angle a is what we need to find. Set the sum of all three of these equal to 180 to solve for angle a.
23+90+angle a= 180. Combine like terms
113 + angle a = 180. Subtract 113 from both sides.
Angle a = 67
Answer:
67⁰
Step-by-step explanation:
According to the Triangle Sum Theorem, all three angles sum up to 180⁰.
<A + <B + <C = 180⁰
You are given the two angles. To find the third or the missing angle you will use the triangle sum thereom.
<A + <B + <C = 180⁰
90⁰ + 23⁰ + <C = 180⁰
113⁰ + <C = 180⁰
113⁰ - 113⁰ + <C = 180⁰ - 113⁰
<C = 67⁰
Hope this helps, thank you :) !!
When is the best time to use square roots to solve a quadratic? Choose the one BEST

B. Difference of squares
C. When there is no b term
D. When the constants are perfect squares
Answer: D, When the constants are perfect squares.
Step-by-step explanation:
the “best” method whenever the quadratic equation only contains x2 terms. That implies no presence of any x term being raised to the first power somewhere in the equation.
