What is the solution to the system of equations shown in the graph?
(1, -3)
(0, 2)
(-2, 0)
(-3, 1)
Answer:
(-3,1)
Step-by-step explanation:
As their are two lines so these are simultaneous linear equations
The solution is the point or coordinate at which they intersect with each otherHence this is (-3,1)
Note: The solution of a graph is the intersection of 2 lines.
Plotting the solution on the graph:
To plot the solution on the graph,
Look for the intersection point of the two lines. Make a dot on the graph to represent the solution.Identifying a solution on the graph:
To identify the solution, you willl need to determine it's coordinates.
1. Determine the x and y coordinate by drawing a line going downwards and rightwards. Keep in mind that the intersection of the lines on the x and y axis are the x and y coordinates repectively.
(It is suggested that the line should be drawn with a ruler).2. The x and y coordinate obtained should be put in (x,y) form.
Determining the solution on the graph:
⇒ Intersection point: (x, y) = (x = -3; y = 1) = (-3, 1) [Refer to image]

Answer:
∠ N = 42°
Step-by-step explanation:
the measure of a secant- secant angle is half the difference of the measures of the intercepted arcs , that is
∠ N = [tex]\frac{1}{2}[/tex] ( HE - XP ) = [tex]\frac{1}{2}[/tex] ( 122 - 38)° = [tex]\frac{1}{2}[/tex] × 84° = 42°
Which statements describe the graph of y = 4x2 28x 49? check all that apply. the graph has two x-intercepts because 4x2 28x 49 has two different factors. the equation 2x 7 = 0 can be used to find a zero of the function. the equation (2x – 7)2 = 0 can be used to find the y-intercept. the graph has a double root at x = startfraction negative 7 over 2 endfraction. the graph intersects the y-axis at y = 49.
The true statements about the graph y = 4x2 + 28x + 49 are as follows;
(b) The equation 2x + 7 = 0 can be used to find a zero of the function.
(d) The graph has a double root at x = -7/2.
(e) The graph intersects the y-axis at y = 49.
What is the function of the graph?The graph of a function f is the graph of the equation y = f (x).
The function is given as:
[tex]\rm y = 4x^2 + 28x + 49[/tex]
Express 28x and 14x + 14x; so, we have:
[tex]\rm y = 4x^2 + 14x+14x + 49[/tex]
Factorize
[tex]\rm y = 4x^2 + 14x+14x + 49\\\\y = 2x(2x+7)+7(2x+7)\\\\y=(2x+7)(2x+7)[/tex]
Express as a perfect square
[tex]\rm y = (2x+7)^2[/tex]
This means that the graph of the equation has a double root.
It also means that 2x + 7 = 0 can be used to determine the root/zero of the function.
Substitute 0 for x in to determine the y-intercept
[tex]\rm y = (2x+7)^2\\\\\rm y = (2(0)+7)^2\\\\\rm y = (0+7)^2\\\\y=49[/tex]
This means that the graph intersects with the y-axis at y = 49
Hence, the true statements are (b), (d), and (e)

Sal and Zack built a scale model of the Texas Capitol using a scale in which 2 inches represents 8 feet. The height of the Texas Capitol is 312 feet.
Problem
What is the height of the scale model in inches?
Fractions are rations of two integers. The height of the scale model in inches is 78 inches
Ratio and proportionsFractions are ratios of two integers and they are also used to represent ratios.
Given that scale model of the Texas Capitol is 2 inches to represents 8 feet, the height of the capitol in inches is the heght in feet is 312 feet is expressed as:
Height = 312 * 2/8
Height in inches = 312/4
Height in inches = 78 inches
Hence the height of the scale model in inches is 78 inches

Answer:
g(-2) = -1
Step-by-step explanation:
By looking at the graph, we can see that g(-2) where x = -2 is represented. Because x = -2, we can see that the y-value that correlates to this x-value is -1.
So g(-2) = -1.

The sum of the 2 numbers is 83. The difference of the 2 numbers is 13. What is the product of the 2 numbers?
Answer:
1680
Step-by-step explanation:
To find the product of the two numbers, you can work out the values of the numbers, or you can work directly with the sum and difference figures.
__
Deriving the formulaWe note that the square of a sum is ...
(a +b)² = a² +2ab +b²
and the square of a difference is ...
(a -b)² = a² -2ab +b²
The difference of these squares is ...
(a +b)² -(a -b)² = (a² +2ab +b²) -(a² -2ab +b²) = 4ab
__
Using the formulaThat is, dividing the difference of the squares of the sum and difference by 4 will give the desired product:
P = (83² -13²)/4 = (6889 -169)/4 = 6720/4 = 1680
The product of the two numbers is 1680.
_____
Additional comment
If we factor the formula we derived, we find ...
P = ((a +b)² -(a -b)²)/4 = ((a +b) +(a -b))/2 × ((a +b) -(a -b))/2
This simplifies to ...
(2a)/2 × (2b)/2 = a × b
In short:
a = ((a +b) +(a -b))/2, the average of the sum and differenceb = ((a +b) -(a -b))/2, half the difference of the sum and differenceUsing this fact, we find a=(83+13)/2 = 48; b=(83-13)/2 = 35, and the product is (48)(35) = 1680, as above.

[tex]v_{f}^{2}= 0 + 2*9.8 * 45[/tex]
= 882 m
[tex]\bold{\huge{\underline{ Answer }}}[/tex]
Answer 1 :-Here, We have
Initial velocity = 0 , as jeepney started from rest Time = 2 seconds Distance = 20 mTherefore,By using second equation of motion
[tex]\sf{ S = ut {\times} }{\sf{\dfrac{1}{2}}}{\sf{at^{2}}}[/tex]
Subsitute the required values,
[tex]\sf{ 20 = 0{\times}2 {\times} }{\sf{\dfrac{1}{2}}}{\sf{{\times}a(2)^{2}}}[/tex]
[tex]\sf{ 20 = }{\sf{\dfrac{1}{2}}}{\sf{{\times}4a}}[/tex]
[tex]\sf{ 20 = 2a }[/tex]
[tex]\sf{ a = }{\dfrac{ 20}{2}}[/tex]
[tex]\sf{ a = 10\:m/s^{2}}[/tex]
Hence, The acceleration of the jeepeny is 10 m/s² .
Answer 2 :-Here, we have
Initial velocity = 0 , as the coins started rolling from rest. Acceleration = 4 m/s²Time = 3 secondsTherefore,
By using second equation of motion
[tex]\sf{ S = ut {\times} }{\sf{\dfrac{1}{2}}}{\sf{at^{2}}}[/tex]
Subsitute the required values,
[tex]\sf{ S = 0{\times}3 {\times} }{\sf{\dfrac{1}{2}}}{\sf{{\times}4(3)^{2}}}[/tex]
[tex]\sf{ S = }{\sf{\dfrac{1}{2}}}{\sf{{\times}4(9)}}[/tex]
[tex]\sf{ S = }{\sf{\dfrac{1}{2}}}{\sf{{\times}36}}[/tex]
[tex]\sf{ S = 18 \: m }[/tex]
Hence, The coin will reach 18 m after 3 seconds.
Answer 3 :-Here,
A stone fell from a 45 m high cliff and hit the ground.So,
Initial velocity = 0Distance = 45 mAcceleration due to gravityBy using third equation of motion

Subsitute the required values,
[tex]\sf{ v^{2} = 0^{2} + 2{\times}9.8{\times}45 }[/tex]
[tex]\sf{ v^{2} = 90{\times}9.8}[/tex]
[tex]\sf{ v^{2} = 882 m}[/tex]
[tex]\sf{ v = \sqrt{882} m}[/tex]
