HELP (0,-3) and (5,-5) what is the slope
Answers
Answer:
-2/5
Step-by-step explanation:
To find the slope, we use the slope formula
m = ( y2-y1)/(x2-x1)
= ( -5 - -3)/( 5 - 0)
= ( -5+3)/( 5-0)
= -2/5

In terms of x, what is the length of the side of a square whose area is represented by the expression 25x^2 + 40x + 16?
Answers
Answer:
Step-by-step explanation:
25x2 − 40x + 16 = (5x)² - 2*5*4 + 4² { (a - b)² = a² - 2ab + b² }
= (5x - 4)² { here a = 50 and b = 4}
Side of the square = 5x - 4 units
Part B:
25x2 − 16y2 = (5x)² - (4y)² { a² - b² = (a + b) * (a - b) }
= (5x + 4y) * (5x - 4y) { here a = 5x and b = 4y}
Dimensions of Rectangle: (5x + 4y) ; (5x - 4y)
Answer:
Step-by-step explanation:
25x²+40x+16=25x²+20x+20x+16
=5x(5x+4)+4(5x+4)
=(5x+4)(5x+4)
=(5x+4)²
length of side=5x+4

70% of _____=42
Answers
Answer:
60
Step-by-step explanation:
70% of x = 42
.7x = 42
x = 42 ÷ .7
x = 60
Answer:
60
Step-by-step explanation:
We have, 70% × x = 42
or,
[tex]\frac{70}{100}[/tex] × x = 42
Multiplying both sides by 100 and dividing both sides by 70,
we have x = 42 × [tex]\frac{100}{70}[/tex]
x = 60
If you are using a calculator, simply enter 42×100÷70, which will give you the answer of 60

John's bicycle covers 60 inches in one revolution. What
is the radius of his tire?
Answers
Answer:
The radius is equal to [tex]\frac{30}{pi}[/tex] or about 9.5 inches
Step-by-step explanation:
A revolution is the same as the circumference,
which can be found using C = 2πr
C = 2πr
60 = 2πr
(2π)r = 60
r = [tex]\frac{60}{2pi}[/tex]
r = [tex]\frac{30}{pi}[/tex] or about 9.5 inches

b. Solve the system to determine how many of each type of coin is in the jar.
Answers
Answer:

Step-by-step explanation:
x+y=100
5x+10y=635
x=100-y
5(100-y)+10y=635
500-5y+10y=635
500+5y=635

Solve for x. The problem is in the picture!!
Answers
Answer:
According to the given Attachment
we know sum of all angles in a triangle is 180° .
Sum of all angles in ∆ = 180°On substituting the given value we obtain
➥ x + 61° + 70° + 61° = 180°
➥ x + 192° = 180°
➥ x = 180° - 192°
➥ x = -12°
So, the value of x is -12°
Step-by-step explanation:
[tex]x + 61 + 70 + 61 = 180(sum \: of \\ \: triangle) \\ \\ x + 192 = 180 \\ \\ x = 180 - 192 \\ \\ x = - 12[/tex]

Additional comment
If you're aware that the area inside a (symmetrical) parabola is 2/3 of the area of the enclosing rectangle, you can compute the desired area as follows.
The parabolic curve is 4-1 = 3 units wide between x=1 and x=4. It extends upward 2.25 units from y=4 to y=6.25, so the enclosing rectangle is 3×2.25 = 6.75 square units. 2/3 of that area is (2/3)(6.75) = 4.5 square units.
This region sits on top of a rectangle 3 units wide and 4 units high, so the total area under the parabolic curve is ...
area = 4.5 +3×4 = 16.5 . . . square units

The length of a picture frame is 6 inches more than the width. For what values of x is the perimeter of the picture frame greater than 148 inches?
Answers
Answer:
The possible values of S are the values between 37 and 49. (Excluding 37 and 49)
Step-by-step explanation:
If the perimeter of the square must be greater than 148 inches but less than 196 inches.
And perimeter of a square = 4s
We intend to find the values of s such that:
148 < 4s
¹⁴⁸⁄₄ < ⁴ˢ/₄
37 < s
Also:
4s < 196
s < ¹⁹⁶⁄₄
s < 49
Therefore:
37 < s < 49.
The possible values of s are the values between 37 and 49. (Excluding 37 and 49.)

Find the area of the shaded region. Use 3.14 as an approximation.
Answers
Answer:
shaded area = 113.64 cm²
Step-by-step explanation:
To find the shaded area, subtract the area of the circle from the area of the triangle.
Area of a triangle = 1/2 x base x height
⇒ area of triangle = 1/2 x 25 x 21.4 = 267.5 cm²
Area of a circle = [tex]\pi r^2[/tex] (where r is the radius)
From inspection, we can see that the diameter of the circle = 14 cm
Therefore, as the diameter = 2r, then r = 14 ÷ 2 = 7 cm
⇒ area of circle = 3.14 x 7² = 153.86 cm²
Shaded area = area of triangle - area of circle
⇒ shaded area = 267.5 - 153.86 = 113.64 cm²
