Answer:
Once. The point of intersection is (-5/7, 3)
Step-by-step explanation:
Once. You have two straight lines here with different slopes, and neither is the negative reciprocal of the other. There is one solution to this system of linear equations.
Setting the two equations equal to each other, we get
y = -4 + 1 = 7x + 2, or
-3 = 7x + 2, or
7x = -5, or x = -5/7.
From the first equation and x = -5/7, we find y:
y = 7(-5/7) + 2, or y = -5 + 2, or y = 3.
The ONE solution is (-5/7, 3)

Elena donates some money to charity whenever she earns money as a babysitter. What percent of her income does She donate?
Answer:
10%
Step-by-step explanation:
The question is incomplete due to missing data
Say she earns $1000
And she donates $100
Hence the percentage of her earnings she donates is
=100/1000*100
=10000/1000
=10%
Hence the percentage is 10%
the measure of five of of the interior angles of a hexagon are 150, 100, 80, 165, and 150. what is the measure of the sixth interior angle?
please help it’s due soon and show the work!!
Answer:
75°
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
Here n = 6 , then
sum = 180° × 4 = 720°
let x be the sixth angle, then sum and equate to 720°
150 + 100 + 80 + 165 + 150 + x = 720
645 + x = 720 ( subtract 645 from both sides )
x = 75
The sixth interior angle is 75°
y=3x +5
y=x+3

TWO points A and B on a plan represent two localities 12 m apart. Given that the segment AB is 6 cm long, find the scale used to draw the plan.
Answer:
The scale used to draw the plan is 1: 200.
Step-by-step explanation:
Given that two points A and B on a plan represent two localities 12 m apart, to determine, given that the segment AB is 6 cm long, the scale used to draw the plan, the following calculation must be performed:
12 m = 12 cm x 100 = 1200 cm
1200/6 = 200
Therefore, the scale used to draw the plan is 1: 200.

Step-by-step explanation:
The class must raise at least 100$ to go on the field trip. They have collected 20$. Write an inequality to represent the amount of money (m) the class still needs to raise.
Answer: 20x < 100
subtract 20 from both sides
20 - 20 = 0
100 - 20 = 80
x < 80

Sandy paid $27 for her new sweater. If the sweater was on sale for 25% off, what was the original price?
Answer:
The answer is $36
Step-by-step explanation:
Took the Star Math Test
Answer:
$36
Step-by-step explanation:
100% - 25% = 75%
75% as a decimal = 0.75
75% = 27
75% as a decimal = 3/4
So 3/4 x = 27
27 x 4 = 108
108 / 4 = 36

Write equation of a line through the points (4,2) and (6,-4)
Answer:
y = -3x - 2
Step-by-step explanation:
to find slope use m= y2-y1/x2-x1
m= -4-2/6-4
m= -6/2
m=-3
then use point slope formula (y-y1) =m(x-x1)
(y-2) = -3(x-4)
simplify
y-2 = -3x - 4
turn into slope intercept form
y = -3x - 2

5. Given AADL AAKM with AD = 14, DK = 21, and
AL= 15. What is the measure of LM?
Answer:
22.5
Step-by-step explanation:
first of all, the first sign in the designations of the triangles is not an A. it is the Greek Delta (capital) sign. standing for "triangle" due to its shape.
as the diagram shows (and the description says correctly), ADL and AKM are similar triangles.
that means they have the same angles.
and in order to keep the same angles even when the lengths of the sides are different, the relative relation of the side lengths must be the same for all sides.
that means, if one side changes by a factor f, then both other sides must change by the same factor.
so, by checking the change factor for AD (to AK), we can then determine the change of AL to AM. and then we simply subtract AL from AM and get LM.
the original AD = 14.
AK = AD + DK = 14 + 21 = 35
the change factor f is then AK/AD = 35/14 = 5/2
in other words AD grew by a factor of 5/2.
AM is then created by applying the same factor to AL.
=> AM = 15 * 5 / 2 = 75 / 2 = 37.5
=> LM = AM - AL = 37.5 - 15 = 22.5

A glide reflection is a composition of a line reflection and a translation that is parallel to the line of reflection. Unlike some composition of transformations, a glide reflection IS ____________________. Therefore, the line reflection and translation can be done in any ____________.
Answer:
" a glide reflection IS commutative. Therefore, the line reflection and translation can be done in any order."
Step-by-step explanation:
Transformations can be written as operators that act on functions or shapes.
For example, we can define the horizontal translation operator as:
T(k)
And if we apply this to a function, we get:
T(k)[ f(x) ] = f(x - k)
Now, the operators are not necessarily commutative.
This means that if we have two operators:
K and L
is not the same:
K[ L[ f(x) ]]
than:
L[ K[ f(x) ]]
An example of this can be a reflection across the y-axis and a horizontal translation, that composition is non-commutative.
Now, let's go to our case.
A glide reflection is commutative, so we can perform the transformations in any order, then the statement is:
" a glide reflection IS commutative. Therefore, the line reflection and translation can be done in any order."
‼️‼️‼️HELP‼️‼️‼️‼️‼️
In the diagram, we can see that the angles are linear pair, which means they are of 180°. Now,
Supplementary angles are those which form an angle of 180° where as Complementary angles are those which form an angle of 90°. Certainly, the as it is a linear pair, they both are supplementary angles.
Now, we can say that:
= x + 118 = 180 ------------ [ Supplementary angles]
= x = 180 - 118
= x = 62
That's how the option B is correct.
❗️❗️❗️please answer fast‼️‼️‼️‼️
Answer:
72°
Step-by-step explanation:
The interior angles of a triangle sum to 180°. Since there are two angles at 54°, we can use the equation x = 180 - 54 - 54 or x = 180 - 2(54), which will give us 72°.
Use the information given to write the equation of the circle
Center: (-9, -3), Point on Circle: (-11,2)
x²+ y²+ 20x + 8y - 84 = 0 is equation of the circle .
What is a circle, exactly?
A circle is a closed, two-dimensional object in which all points in the plane are equally spaced apart from the center.
The symmetry line of reflection is formed by each line that traverses the circle. Additionally, it is rotationally symmetric about the center for all angles.
the equation of the circle with center (-10,-4) and a point on the required circle is (4,-2).
Clearly, radius of the circle will be distance between the center and the point on the circle.
r = √( -10 - 4 )²+ ( -4 + 2 )²
r = √196 + 4
r = 10√2
We know that circle with center at (h.k) and radius r has the equation
( x - h )² + ( y - k )² = r²
We have circle with radius 10√2 and center at (-10,-4) and its equation will be
( x+ 10 )² + ( y + 4)²= ( 10√2)²
x²+ y²+ 20x + 8y - 84 = 0

Estimate 11.14+9.543 by first rounding each number to the nearest tenth.
HELP PLSZZ
To round each number to the nearest tenth, we have to look at the second digit after the decimal point, the hundredths. We look at tenths to round whole numbers, hundredths to round tenths, thousandths to round hundredths, etc. If the digit is 4 or below, then we would round down. If the digit is 5 or up, we would round up.
11.14
The digit is below 5, so we round down to 11.1.
9.543
The digit is also below 5, so we round down to 9.5.
Henceforth, adding these two numbers, we can conclude that an accurate estimation of the sum is 11.1 + 9.5, or 20.6.
If we wanted to round this answer further, we would use the same rounding rule. 20.6, where the tenths place digit, 6, is above 5, would be rounded up to 21.
