Answer:
1. x - 12 = 14 {brother's age minus 12 equals sister's age}
x = 26 {added 12 to each side}
Your brother is 26.
2. x+8.95=21.35
now you must subtract 8.95 by both sides which equals x =12.4
3. 29 compact cars.
The total number of vehicle is 37. So you can just subtract 37 by 8 which gives 29.
4. x +73=95
subtract both sides by 73. which equals 22
5. $160 He originally spent $123.45 and was left with $36.55 you just add both numbers and that's what you get altogether.
6. X-225=548
Solve for x
Add 225 to both sides. So x - 753

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)

The sum of the given series 4, 7, 10, 13, 16, 19, 22, 25, 28, 31, 34, 37, 40 will be 286.
What is a series?A series is a sum of sequence terms. That is, it is a list of numbers with adding operations between them.
The series is given below.
4, 7, 10, 13, 16, 19, 22, 25, 28, 31, 34, 37, 40
Then the sum of the series will be

here it is : Forty of Laurens 50 answers were correct .What percent of Laurens answers were correct.
Answer:
80%
Step-by-step explanation:
using equivalent fractions:
40/50 = 80/100 = 80%
also since 50 is half of 100 (in other words 100%), you can just multiply 40 by 2 to get a number out of 100 which is your percentage

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

[tex]\sf \boxed{v_{f}^{2}=v_{i}^{2}+2gd_{y}}\\\\v_{f} - > final \ velocity\\\\v_{i} - > Initial \ velocity = 0 \\\\d_{y} - > distance \ travelled[/tex]
g -> gravitational acceleration = 9.8 m/s²
[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
[tex]\sf{ v^{2} = u^{2} + 2gs }[/tex]
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]
[tex]\sf{ v = 29.7 m/s}[/tex]
Hence, The final velocity of the stone when the stone hits the ground is 29.7 m.
