Answer:
The equation of the line is;
y = -2x + 2
Step-by-step explanation:
Here, we want to write the equation of the line that passes through the given points
The general form of the equation is
y = mx + b
where m is the slope of the line and b is the y-intercept of the line
Mathematically, to get the slope, we use the slope formula
m = (y2-y1)/(x2-x1)
(x1,y1) = (-2,6)
(x2,y2) = (3,-4)
m = (-4-6)/(3+2) = -10/5 = -2
So the equation is in the form;
y = -2x + b
To get b, we substitute any of the two points
6 = -2(-2) + b
6 = 4 + b
b = 6-4 = 2
The equation of the line is thus;
y = -2x + 2
Estimate the sum by rounding each number to the nearest half or whole.

6.A = 23 × 3 × 5 B = 22 × 3 × 52
Write down the highest common factor (HCF) of A and B.Required to answer. Single line text.
(1 Point)
Given:
The two numbers are
[tex]A=23\times 3\times 5[/tex]
[tex]B=22\times 3\times 52[/tex]
To find:
The highest common factor (HCF) of A and B
Solution:
We have,
[tex]A=23\times 3\times 5[/tex] ...(i)
[tex]B=22\times 3\times 52[/tex]
All the factors of A are prime but the factors of B are not prime. So, it can be written as
[tex]B=2\times 11\times 3\times 13\times 2\times 2[/tex] ...(ii)
From (i) and (ii), it is clear that 3 is the only common factor of A and B. So,
[tex]HCF(A,B) = 3[/tex]
Therefore, the highest common factor (HCF) of A and B is 3.

An isosceles triangle has an angle that measures 118°. Which other angles could be in that isosceles triangle? Choose all that apply. a 69° b 31 c 118 d 54
Answer:
b. 31.
Step-by-step explanation:
The other 2 angles in the triangle are congruent so they are:
(180 - 118) / 2
= 31 degrees.
The possible measure of two similar angles in an isosceles triangle could be b. 31 °
What is a triangle?A triangle is a three-sided closed-plane figure formed by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.
We know in an isosceles triangle two sides are equal and angles opposite sides to the equal side are also equal.
We also know that the sum of all the interior angles in a triangle is 180°.
Let, The similar angles be 'x'.
Therefore,
x + x + 118 = 180
2x = 62.
x = 31°.

Step-by-step explanation:
Explain why the product of a non-0 rational number and an irrational number is irrational?
Answer:
An irrational number is a number that can not be written as the quotient of two integer numbers.
Then if we have:
A = a rational number
B = a irrational number.
Then we can write:
A = x/y
Then the product of A and B can be written as:
A*B = (x/y)*B
Now, let's assume that this product is a rational number, then the product can be written as the quotient between two integer numbers.
(x/y)*B = (m/n)
If we isolate B, we get:
B = (m/n)*(y/x)
We can rewrite this as:
B = (m*y)/(n*x)
Where m, n, y, and x are integer numbers, then:
m*y is an integer
n*x is an integer.
Then B can be written as the quotient of two integer numbers, but this contradicts the initial hypothesis where we assumed that B was an irrational number.
Then the product of an irrational number and a rational number different than zero is always an irrational number.
We need to add the fact that the rational number is different than zero because if:
B is an irrational number
And we multiply it by zero, we get:
B*0 = 0
Then the product of an irrational number and zero is zero, which is a rational number.
3. Are these figures congruent?
A Yes, they are congruent.
B) No, they are not congruent.
Answer:
B) No, they are not congruent.
One ∆ is smaller than the other & hence they are not congruent.
Answer:
B
Step-by-step explanation:
If they were to be congruent, they would have to be the same size and look the same in all aspects including angles and side lengths, but they aren't as they are similar shapes, therefore B.

How do i find this slope?!?!?!
Answer:
Step-by-step explanation:
To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points.
Here are the equations you can use to find the slope;
Slope. y2 - y1 / x2 - x1 = slope.
Slope Intercept form. y = mx + b.
Point slope form. y - y1 = m ( x - x1)

Answer:
1. YES 2. NO
Step-by-step explanation:
1. Since x=0.121212... and the question is asking for 100x, we need to multiply each side by 100. 0.121212... multiplied by 100 is 12.1212... So YES, 100x is still a repeating decimal.
2. 12.121212... minus 0.121212... would just be 12. This is because if we know that all the numbers behind the decimal point is 0.121212 and so on, 12.121212... minus 0.121212... the numbers behind the decimal would cancel out. So we are left with 12. So NO, the answer for 99x is NOT a repeating decimal.

Answer:
One property of rectangles is that the diagonals of rectangles bisect each other, meaning 2 of JN is equal to JL.
We can form an equation off of this, 2(x+3) = 3x + 1 and then solve for x
2(x+3)= 3x + 1 First, distribute the 2 to each term in x+3,
the result should be:
2x + 6 = 3x+ 1 then subtract 2x from both sides
-2x -2x
the result should be :
6 = x + 1 subtract 1 from both sides
-1 -1
the result should be x=5
plug that into the equations and JN= 5+3, JL=15+1
The two correct options are
NM = 8 ( both of the diagonals are equal to eachother )
JL = 16

Write the slope-intercept form of the equation of each line.
Step-by-step explanation:
you look at how the line intersects with an integer point.
on the y-axis, the line has a value of -2 so it has a y-intercept value of -2
so the slope formula is rise/run.
As we can see on the graph, there is no line on the graph that truly lines up with a point besides (0,-2)
if we look at all of the slopes
from A,B,C, and D, and there are not any slopes besides d that are on the graph.
y=mx+b
m=slope
b=y-intercept
If we expand the graph a little bit we can see that the point (0,-2) goes up 7 and goes to the left of 4 units.
so the answer is D : y=-7/4x-2
----------------------------------------------------------------------
and since we go up and to the left or we go down and to the right that determines that the slope is negative.
If we started on a point on the y-axis, and started and went up and to the right or down and to the left.
Hope that helps :)

Find the value of y. Round your answers to the nearest tenth
Answer:
y ≈ 4.3
Step-by-step explanation:
Since the figures are similar then the ratios of corresponding sides are equal, that is
[tex]\frac{AB}{RS}[/tex] = [tex]\frac{ED}{VU}[/tex] , substitute values
[tex]\frac{6}{4}[/tex] = [tex]\frac{8}{y+1}[/tex] ( cross- multiply )
6(y + 1) = 32
6y + 6 = 32 ( subtract 6 from both sides )
6y = 26 ( divide both sides by 6 )
y ≈ 4.3 ( to the nearest tenth )
Answer:
4.3 Is the answer like the value of X in the nearest tenth.

Decrease £843 by 91% rounded to 2 DP
Answer:
Percent (%)' means 'out of one hundred':
p% = p 'out of one hundred',
p% is read p 'percent',
p% = p/100 = p ÷ 100.
91% = 91/100 = 91 ÷ 100 = 0.91.
100% = 100/100 = 100 ÷ 100 = 1.
Decrease number by 91% of its value.
Percentage decrease = 91% × 843
New value = 843 - Percentage decrease
Calculate the New Value
New value =
843 - Percentage decrease =
843 - (91% × 843) =
843 - 91% × 843 =
(1 - 91%) × 843 =
(100% - 91%) × 843 =
9% × 843 =
9 ÷ 100 × 843 =
9 × 843 ÷ 100 =
7,587 ÷ 100 =
75.87
Calculate absolute change (actual difference)
Absolute change (actual difference) =
New value - 843 =
75.87 - 843 =
- 767.13
Proof.
Calculate percentage decrease:
Percentage decrease =
91% × 843 =
91 ÷ 100 × 843 =
91 × 843 ÷ 100 =
76,713 ÷ 100 =
767.13
