Answer:
7. y=x-2, 8. y=3/2x+4, 9. y=-3/4x+8, 10. y=2x-7, 11. y=-5x-3, 12. y=4x-5, 13. y=-3x-1, 14. y=-1/2x+1, 15. y=3/2x+4
Step-by-step explanation:
First you have to plug in the points into y2-y1/x2-x1. This would make it -2-0/0+1. Simplify this to get -2/1 which is -2. This makes the slope -2. Then plug in the slope into point intercept form y-y1=m(x-x1) where m is the slope. This time, I will use the point (0,-2). Therefore, the equation will be y+2=1(x-0) which is equal to y+2 =x-0 which is equal to y=x-2.
This is how you do all of the problems. For problem 13-15, you know that f(0)=-1 is (0,-1) and f(3)=-10 is (3,-10). Then you can solve the problems. I will not explain every single problem but will give you the answers.

What is the area of a triangle whose base measures 3.2 centimeters and whose height is 4.6 centimeters.
Answer:
7.36 cm²
Step-by-step explanation:
What is the area of a triangle whose base measures 3.2 centimeters and whose height is 4.6 centimeters.
The formula for the area of a triangle is given as:
1/2 × Base × Height
Base = 3.2 cm
Height = 4.6 cm
Hence,
Area of the triangle = 1/2 × 3.2 × 4.6
= 7.36 cm²

What is the measure of the indicated angle?
Answer:
76
Step-by-step explanation:
Let the indicated angle be x
all the angels add up to 180⁰
therefore,
x + 48 + 56 = 180
x + 104 = 180
x = 180 - 104
x = 76

Step-by-step explanation:
find the area of the figure below, composed of a rectangle and semicircle. Round it to the nearest tenth.
Answer:
Step-by-step explanation:
radius of semicircle = 5
area of semicircle = πr² = 25π
area of rectangle = 10×14 = 140
total area = 140 + 25π ≅ 218.54 square units

What is an equation of the line that passes through the points (4, -6) and
(8,-4)?
Answer:
y = 1/2x - 8
Step-by-step explanation:
(4, -6) & (8, -4)
First you want to find the slope of the line that passes through these points. To find the slope of the line, we use the slope formula: (y₂ - y₁) / (x₂ - x₁)
Plug in these values:
(-4 - (-6)) / (8 - 4)
Simplify the parentheses.
= (2) / (4)
Simplify the fraction.
2/4
= 1/2
This is your slope. Plug this value into the standard slope-intercept equation of y = mx + b.
y = 1/2x + b
To find b, we want to plug in a value that we know is on this line: in this case, I will use the second point (8, -4). Plug in the x and y values into the x and y of the standard equation.
-4 = 1/2(8) + b
To find b, multiply the slope and the input of x(8)
-4 = 4 + b
Now, subtract 4 from both sides to isolate b.
-8 = b
Plug this into your standard equation.
y = 1/2x - 8
This is your equation.
Check this by plugging in the other point you have not checked yet (4, -6).
y = 1/2x - 8
-6 = 1/2(4) - 8
-6 = 2 - 8
-6 = -6
Your equation is correct.
Hope this helps!
The ratio 2 centimetres to 5 metres can be written in the form
1
:
n
.
Find the value of
n
.
Answer:
n = 250
Step-by-step explanation:
To express the ratio, the quantities must have the same measures
2 cm : 5 m
= 2 cm : 500 cm [ 1 m = 100 cm ]
Divide both parts by 2
= 1 : 250 → with n = 250
Which is the better deal?
6 cans of soda for $3.60
4 cans of soda for $2.36
10 cans of soda for $5.50
Answer:
The better deal is 10 cans of soda for $5.50
Step-by-step explanation:
6 cans of soda for $3.60 means each can of soda is worth .60 cents4 cans of soda for $2.36 means each can of soda is worth .59 cents 10 cans of soda for $5.50 means each can of soda is worth .55 centsTherefore, 10 cans of soda for $5.50 is the best deal because you are getting the most cans of soda for the cheapest amount of money.
Hope this helped!
Answer:
10 cans for $5.50
Step-by-step explanation:
3.60/6= $0.60 per can
2.36/4= $0.59 per can
5.50/10= $0.55 per can

Answer:
ITS 1
10 = 2 • 5

45 = 32 • 5
Answer:
GCF of 40 and 60
Step-by-step explanation:
Solution We first express 20 and 60 as the product of prime numbers 40 = 2 × 2 × 2 × 5 60 = 2 × 2 × 3 × 5. The common factors are 2 × 2 and 5.
Select the correct answer. Which equation represents the line that is parallel to y = 3 and passes through (-2,-8)? A. x = -2 B. x = 3 C. y = -8 D. y = 3x − 2
Answer:
C. -8
Step-by-step explanation:
Don't listen to ppl who say it's 3, IT'S NOT. The answer is C. y= -8, because the line has to be parallel so it will be y and D is clearly not correct, so its C.
Answer:
c=-8

If BE = 2x + 2, BD = 5× - 3, and AE = 4× - 6, what are the values of x and AC?
Answer:
x = 7
AC = 44
Step-by-step explanation:
Find the diagram attached
According to the parallelogram,
BD = 2BE
5x-3 = 2(2x+2)
5x-3 = 4x+4
5x-4x = 4+3
x = 7
Hence the value of x is 7
Also AC = 2AE
AC = 2(4x-6)
AC = 8x - 12
AC = 8(7) - 12
AC= 56-12
AC = 44
Hence the measure of AC is 44
