Answer:
y = 5x-5
Step-by-step explanation:
First find the slope
m = ( y2-y1)/(x2-x1)
= ( 10-5)/(3-2)
= 5/1
=5
Using slope intercept form
y = mx+b
y = 5x+b
Substituting a point into the equation
5 = 5*2+b
5 = 10+b
Solving for b
5-10 = b
-5 =b
y = 5x-5

The Royal Fruit Company produces two types of fruit drinks. The first type is 35% pure fruit juice, and the second type is 100% pure fruit juice. The company is attempting to produce a fruit drink that contains 45% pure fruit juice. How many pints of each of the two existing types of drink must be used to make 260 pints of a mixture that is 45% pure fruit juice?
Answer:
first type of fruit juice (35%) = 4
second type of fruit juice (100%) = 4
Step-by-step explanation:
4×35 = 140
4×100 = 400
400-140 = 260

Question 7 (5 points)
(06.04 LC)
The equation of the line of best fit of a scatter plot is y = 8x - 1. What is the slope of
the equation? (5 points)
1)-8
2-1
3) 1
4) 8
Answer:
4) 8
Step-by-step explanation:
In the formula y = mx + b, m is the slope and b is the y-intercept
m = 8
b = -1
If m = 8 and m is the slope, then the slope is 8

Show work to triangles 2 and 3 explaining why they are right triangles
Answer:
Step-by-step explanation:
In order for a triangle to be a right triangle, it has to fit into Pythagorean's Theorem:
[tex]a^2+b^2=c^2[/tex] where c is the hypotenuse.
We need to figure out which is the longest side in each of those triangles and that is the hypotenuse.
In the first set, the sqrt of 443 is 21.04, but that is not the longest side; 24 is. So the Theorem formula for that is:
[tex]\sqrt{443}^2+17^2=24^2[/tex] which gives us
443 + 289 = 576, but 732 does not equal 576, so that one is not right.
In the second set, the sqrt of 725 is the longest side, so that formula is:
[tex]\sqrt{725}^2=14^2+23^2[/tex] which gives us
725 = 196 + 529, and 725 does equal 725, so that one is right.
In the third set, the sqrt of 890 is the longest side, so:
[tex]\sqrt{890}^2=19^2+23^2[/tex], which gives us
890 = 361 + 529, and 890 = 890, so that is a right triangle as well. That's how you know those are right, compared to the first one that is not.
please help im literally crying i cant fail this please
Help it is past due!!! One hundred points
i wont give the answer but i will tell you how to solve
Opening Exercise
The original triangle, labeled A, has been reflected across the first line, resulting in the image labeled B. Reflect the image across the second line. Carlos looked at the image of the reflection across the second line and said, “That’s not the image of triangle A after two reflections; that’s the image of triangle A after a rotation!” Do you agree? Why or why not?
Discussion
When you reflect a figure across a line, the original figure and its image share a line of symmetry, which we have called the line of reflection. When you reflect a figure across a line and then reflect the image across a line that intersects the first line, your final image is a rotation of the original figure. The center of rotation is the point at which the two lines of reflection intersect. The angle of rotation is determined by connecting the center of rotation to a pair of corresponding vertices on the original figure and the final image. The figure above is a 210° rotation (or 150° clockwise rotation).
Exploratory Challenge
Line of symmetry of a figure: This is an isosceles triangle. By definition, an isosceles triangle has at least two congruent sides. A line of symmetry of the triangle can be drawn from the top vertex to the midpoint of the base, decomposing the original triangle into two congruent right triangles. This line of symmetry can be thought of as a reflection across itself that takes the isosceles triangle to itself. Every point of the triangle on one side of the line of symmetry has a corresponding point on the triangle on the other side of the line of symmetry, given by reflecting the point across the line. In particular, the line of symmetry is equidistant from all corresponding pairs of points. Another way of thinking about line symmetry is that a figure has line symmetry if there exists a line (or lines) such that the image of the figure when reflected over the line is itself.
Does every figure have a line of symmetry?

(iii) A relation between a and b such that point (a,b) isequidistant from the points (8,3) and (2,7)
Answer:
7.21 units
Step-by-step explanation:
GIven data
Point 1= (8,3)
x1= 8
y1= 3
Point 2= (2,7)
x2= 2
y2= 7
The expression for the distance between two points is given as
d=√((x_2-x_1)²+(y_2-y_1)²)
substitute
d=√((2-8)²+(7-3)²)
d=√((-6)²+(4)²)
d=√36+16
d=√52
d= 7.21
Hence the distance between the points is 7.21 units

f(x)=18,000(1-0.012)^x ; x represents the number of years since the car started to depreciate and 18,000 = the initial value of the car. What year will you recieve the car when the car value drops below $2,000? Please do a step by step
Answer:
Given
f(x)=18,000(.88)^x
We need to find the value of x when f(x) <2000
2000 = 18000(0.88)^x
0.88^x 2000/18000
0.88^x 1/9
• x = log (1/9) / log (0.88)
• x= 17 (rounded down)
After 17 years or during year 18 the car value will drop below $2000
Work out the size of angle A.

38°
Answer:
38° because the other two are cm? also you haven't linked a photo so I can't work out angle A
Х
49°
Xa
degrees
please help
Answer:
x = 139 degrees
Step-by-step explanation:
first, find what the missing interior angle is:
add the known angles:
90 + 49 = 139
subtract the sum from 180:
180 - 139 = 41
now to solve for x, take 180 and subtract 41:
180 - 41 = 139
x = 139 degrees
5. The area of the greatest square that is cut from a rectangle of sides
7cm and 4cm is
(1)
49sq.cm (ii) 28sq.cm (iii) 16sq.cm (iv) 9sq.em
Answer:
16 cm²
Step-by-step explanation:
The dimension of rectangle = 7cm by 4 cm
The Area of the greatest square that can be cut from the rectangle :
The dimension has to be the Same to form a square :
Hence, the greatest width = 4cm
Therefore, taking the length also as 4cm
Area of square = side length²
Greatest area of square that can be cut = 4² = 16cm²

Solve the inequality? -4/9>10w
Answer:
w < -2/45
Step-by-step explanation:
To solve the inequality, solve for w.
Divide each side by 10:
-4/9 > 10w
-2/45 > w
So, the solution to the inequality is w < -2/45
Answer:
w<-2/45
w∈(-∞,-2/45)
Step-by-step explanation:
10w<-4/9 /10
w<-2/45
w∈(-∞,-2/45)
