After using the linear equation - The smaller number is 7, and the greater number will be 23.
what is the substitution method?
Mathematicians frequently use the substitution method to resolve an equation system. With this method, you solve the equation for the first variable first, and then plug the answer into the second equation.
what is a linear equation in two variables?
When an equation is written in the form axe + by + c=0 and the coefficients of x and y, i.e., a and b, respectively, are not equal to zero and the greater of the two numbers is four times the smaller number minus 5, that equation is said to be linear in two variables.
Let's assume that "x" is the smaller number, making "4x-5" the greater number. The requirement that the difference between the two numbers be 16 is also included.
thus,
4x - 5 - x = 16
3x -5 = 16
3x = 16 +5
3x =21
x = 21/3
x = 7

Choose the point-slope form of the equation below that represents the line that passes through the point (6, -3) and has a slope of 1/2OPTIONS: A.) y-6 = 1/2(x+3)B.) y = 1/2x - 6C.) y+3 = 1/2(x-6)D.) y-2y = 12
Answers
ANSWER
B) y = 1/2x - 6
EXPLANATION
We have that the line passes through (6 -3) and has a slope of 1/2.
To find the point-slope form of the equation, we have to use the formula:
[tex]y-y_1=m(x-x_1)[/tex]where m = slope = 1/2
(x1, y1) = (6, -3)
So, we have:
y - (-3) = 1/2 (x - 6)
y + 3 = 1/2 x - (1/2 * 6)
y + 3 = 1/2 x - 3
=> y = 1/2x - 3 - 3
y = 1/2x - 6

A football team scored a total of 50 points in one game. They scored 14 times. The scoring
was made up of touchdowns (6 points each), field goals (3 points each), and PATS (1 point
each). They had 3 more touchdowns than field goals. How many of each type of score did the
team have?
Answers
Answer:
Touchdowns: 6
Field goals: 3
PATS: 5
Step-by-step explanation:
6*6 = 36
3*3 = 9
5*1 = 5
9+5+36 = 50 points
6+3+5 = 14 scored times
Answers:
6 touchdowns (TD)
3 field goals (FG)
5 points after touchdown (PAT)
===============================================
Explanation:
Acronyms used in football
PAT = point after touchdownTD = touchdownFG = field goalDefine the following variables
x = number of TDsy = number of FGsz = number of PATs"They had 3 more touchdowns than field goals", so,
TD = FG + 3
x = y + 3
They scored 14 times which means we can say
x+y+z = 14
Let's look at the point breakdown per type of score
TDs give 6 points each. Scoring x of them gives 6x pointsFGs give 3 points each. Scoring y of them gives 3y pointsPATs give 1 point each. Scoring z of them gives 1z pointsThen we can add up those expressions to get us to 6x+3y+1z = 50 points total. This is the same as saying 6x+3y+z = 50.
--------------------------
Here's our system of equations
x = y+3
x+y+z = 14
6x+3y+z = 50
Let's replace each x with y+3 in the second equation. Then solve for z.
x+y+z = 14
y+3+y+z = 14
2y+z = 14-3
2y+z = 11
z = 11-2y
Now replace every x with y+3 in the third original equation
6x+3y+z = 50
6(y+3)+3y+z = 50
6y+18+3y+z = 50
9y+z = 50-18
9y+z = 32
Then plug in z = 11-2y and solve for y
9y+z = 32
9y+11-2y = 32
7y+11 = 32
7y = 32-11
7y = 21
y = 21/7
y = 3 is the number of FGs scored
Use this to find z
z = 11-2y
z = 11-2(3)
z = 11-6
z = 5 is the number of PATs scored
Now let's find x
x = y+3
x = 3+3
x = 6 is the number of TDs scored
--------------------------
Checking the answers:
x+y+z = 6+3+5 = 9+5 = 14 times they scored
6x+3y+z = 6*6+3*3+5 = 36+9+5 = 50 points scored
There are 3 more TDs than FGs since x = y+3 leads to 6 = 3+3 which is a true statement.
All three original equations we set up for the system of equations are true. Therefore, the final answers are confirmed.

The equation of the line is y = -3x + 8.
What exactly is slope?
The slope of a line, or angle between it and the horizontal, is stated numerically. The slope of a line, ray, or line segment in analytical geometry is the ratio of its vertical to horizontal distance between any two locations ("slope equals rise over run").
Given,
x1 = 1
y1 = 5
m = -3
From,
y-y1 = m(x-x1) (x-x1) (x-x1)
y - 5 = -3(x - 1) (x - 1) (x - 1)
y-5 = -3x + 3
y = -3x + 8

Answers
a. The rocket splashes down after 31.23 seconds.
b. The rocket is 1374.7 meters above sea level.
NASA launches a rocket at t=0 seconds.
Its height, in meters above sea-level, as a function of time is given by
h(t)=-4.9t²+142t+346.
Assuming that the rocket will splash down into the ocean, at what time does splashdown occur?
When splash down occurs, h(t) = 0, therefore
-4.9t²+142t+346 = 0
find t using the quadratic formula; a=4.9, b=142, c=346
t = -142 ± √(142)² - 4(-4.9)(346) / 2(-4.9)
t = -142 ± 164.15 / -9.8
t = -142+164.15/-9.8 , -142-164.15/-9.8
t = 22.15/-9.8 , -306.15/-9.8
t = -2.26 , 31.23
time cannot be negative so t = 31.23
The rocket splashes down after 35.8229 seconds.
The max occurs on the axis of symmetry, use x=-b/(2a) to find it
t = -142/2(-4.9)
t = 142/9.8
t = 14.48 sec
replace t with 17.2449 in the equation
h(t) = -4.9(14.48)² + 142(14.48) + 346
= 1374.7 m
The rocket peaks at 1374.7 meters above sea-level.

LaTanya buys 6 yards of blue fabric and 9 yards of green fabric. The blue fabric costs $2 more per yard than the green fabric. She pays a total of $57. What would be the combined cost of 1 yard of blue fabric and yard of green fabric?
Answers
The price of 1 yard of blue fabric and 1 yard of green fabric is obtained by solving the system of linear equations and it is $8
Let
x = price of blue fabric per yard
y = price of green fabric per yard
"The blue fabric costs $2 more per yard than the green fabric" means:
x = y + 2 (Equation 1)
" LaTanya buys 6 yards of blue fabric and 9 yards of green fabric and pays $57" means:
6x + 9y = 57 (Equation 2)
Substitute equation 1 into equation 2:
6x + 9y = 57
6 (y + 2) + 9y = 57
6y + 12 + 9y = 57
15 y = 45
y = 3
Substitute y = 3 into equation 1
x = 3 + 2 = 5
Hence, the price of blue fabric is $5 per yard while the green fabric is $3 per yard.
The price of 1 yard of blue fabric and 1 yard of green fabric = x + y = 3 + 5 = $8

Answers
120 children and 120 adults were admitted to the amusement park if the admission fee collected was $1980.00
The number of children and adults that entered the park can be calculated using linear equations.
Considering x to be the number of adults and y to be the number of children;
As 240 people entered the park, therefore;
x + y = 240
As the fee for children is $3.50 and for adults is $13, therefore;
13x + 3.50y = 1980
Determining the value of y in the first equation;
x + y = 240
y = 240 - x
Putting this value of y in the second equation;
13x + 3.50y = 1980
13x + 3.50(240 - x) = 1980
13x + 840 - 3.50x = 1980
9.5x = 1980 - 840
9.5x = 1140
x = 1140 / 9.5
x = 120
To determine the value of y, we Substitute this value of x in the first equation;
y = 240 - x
y = 240 - 120
y = 120
Hence, 120 children and 120 adults entered the park if the admission fee for children was $3.50 and for adults was $13.00

How do you determine the line's equation?In order to put the equation in y-intercept (y = mx + b) form and determine the equation of a graphed line, first determine the slope and y-intercept.
It is given that a line's equation passes through point (3,-5) and is perpendicular to y = -x+5.
Slope of given line = -1
Slope of line perpendicular to the given line = Negative of the reciprocal of the slope of a given line = 1
We have the slope and point (3,-5) of the required line. So, we can find the constant of this equation.
y = mx + c
-5 = 1(3) + c
c = -5 - 3
c = -8
Substituting c = -8 and m = 1 to get the equation of required line.
y = mx + c
y = x - 8

Equation
y = x^2 + 8x - 6 Put brackets around the first 2 terms
y = (x^2 + 8x) - 6 Take 1/2 the second term and square
8/2 = 4; 4^2 = 16 Put 16 after the second term
y = (x^2 + 8x + 16) - 6 Subtract 16 and put it after the 6
y = (x^2 + 8x + 16) -6-16 Combine
y = (x^2 + 8x + 16) - 22
The first 3 terms make a perfect square (x^2 + 8x + 16) = (x + 4)^2
So the answer is between C and A

a slope = 0 means that the y coordinate change is always 0, so y does not change anywhere on the line.
that makes y a constant c, and x can be any value completely independent of y.
the line is the summary of all points that have c as their y coordinate.
so, the general equation for such a line is simply
y = c
what is c ?
as we have one point on the line, remember the statement above : the line is the summary of all points that have c as their y coordinate.
that means (3, -4) must have the same y coordinate.
so, c = -4.
the equation of the line is therefore
y = -4
