Answer:
See answers below
Step-by-step explanation:
Equation of a line in point slope form is expressed as;
y-y0 = m(x-x0)
m is the slope
(x0, y0) is a point on the line
Given the line y = x
The slope of the line is 1.
The slope of the line perpendicular is M = -1
Given the point (2,2)
x0 = 2 and y 0 = 2
Substitute
Recall y-y0 = m(x-x0)
y - 2 = -1(x-2) (Point slope form)
Express in slope intercept form;
y - 2 = -1(x-2)
Make y the subject of the formula;
y -2 = -x + 2
y = -x + 2 + 2
y = -x + 4 (slope intercept form)
The general form of linear equation is expressed as the slope intercept form which is y = -x+4
let y = f(x)
f(x) = -x+4
f(x) = 4-x (Linear equation)

Suppose you know that ∠S and ∠Y are complementary, and that m∠S = 5(m∠Y) −240°. Find m∠Y.
The value of m∠Y is
9514 1404 393
Answer:
∠Y = 55°
Step-by-step explanation:
Complementary angles have a sum of 90°.
∠S + ∠Y = 90°
(5∠Y -240°) +∠Y = 90°
6∠Y = 330° . . . . . . . . . . . . add 240°, collect terms

Find the missing angle.
(look at the picture)
Answer: 45
Step-by-step explanation:
59 + 76= 135
180-135= 45
Answer:
m∠1 = 45 degrees
Step-by-step explanation:
All triangles have the interior angle of 180
to find the missing angle, take the known angles and add them together:
76 + 59 = 135
then take the sum and subtract it from 180:
180 - 135 = 45

Answer:
Step-by-step explanation:
1) All the sides are equal. So it is an equilateral triangle. SO, all the angles are equal

what two numbers multiply to 56 and add to -15
Answer:
-7 and -8
Step-by-step explanation:
because 7 times 8 equals 56 and negative times a negitive equals a positive and -7 added to -8 equals -15
The pair of numbers which fulfill the given condition 2.6 & -1.76
and -17.6 & 2.6.
What is a quadratic equation ?An equation is quadratic in form if it can be written in the form of ax + bx + c = 0, where a, b, and c are constants and x is the variable.
Let x and y be the two numbers we're trying to find. We know that:
x * y = 56 (equation 1)
x + y = -15 (equation 2)
y = -15 - x (equation 3)
Substituting equation 3 into equation 1, we get:
x * (-15 - x) = 56
-x² - 15x + 56 = 0
x² + 15x - 56 = 0
Using the quadratic formula, we get:
x = (-b ± √(b² - 4ac)) / 2a
where a = 1, b = 15, and c = -56.
Substituting the values, we get:
x = (-15 ± 20.2) / 2
x = (-15 + 20.2) / 2 = 2.6
x = (-15 - 20.2) / 2 = -17.1
For x = 2.6:
y = -15 - x = -15 - 2.6 = -17.6
So, one possible pair of numbers is x = 2.6 and y = -17.6.
For x = -17.1:
y = -15 - x = -15 - (-17.1) = 2.1
So, another possible pair of numbers is x = -17.1 and y = 2.1.
Therefore, the two numbers that multiply to 56 and add to -15 are approximately -17.1 and 2.6, or vice versa.

Step-by-step explanation:
Members of a soccer team raised $1719 to go to a tournament. They rented a bus for
$1051.50 and budgeted $44.50 per player for meals. Write and solve an equation
which can be used to determine z, the number of players the team can bring to the
tournament.
Answer:
44.5x + 1051.5 = 1719
x = 15
Step-by-step explanation:
DeltaMath
The number of players the team can bring to the tournament is 15.
Given:
The total amount of money raised by the soccer team = $1719
Amount to rent the bus = $1051.50
Amount budgeted for each player's meal = $44.50
To find:
Equation and the number of players the team can bring to the tournament
Solution:
The number of players the team can bring to the tournament = z
Amount budgeted for each player's meal = $44.50
Total amount needed for z number of players' meals = $44.50z
Amount to rent the bus = $1051.50
The total amount of money raised by the soccer team = $1719
The equation for numbers of players will be written as:
[tex]\$44.50z+ \$1051.50= \$1719\\\$44.50z= \$1719- \$1051.50\\\$44.50z=\$667.50\\z=\frac{\$667.50}{\$44.50}=15[/tex]
The number of players the team can bring to the tournament is 15.

Answer:

Step-by-step explanation:
when something is to the power of 1/2, that means you square root it
when it is to the power of a third, that means you cube root it.
for example, if it is 25 to the power of a half, that means [tex]\sqrt{25} = 5[/tex] because
5 x 5 = 25
this is the same concept
we need to find a number that multiplies itself 3 times and equals to 125
5x5x5 = 125, meaning that
125 to the power of a third, is 5.
