The line passing through points (5,) and (2,−3) is parallel to a line with a slope of 4/3. What is the value of y?
Answer:
Step-by-step explanation:
Parallel lines have same slope
Slope = [tex]\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
[tex]\dfrac{-3-y}{2-5}=\dfrac{4}{3}\\\\\\\dfrac{-3-y}{-3}=\dfrac{4}{3}\\\\\\-3-y=\dfrac{4}{3}*(-3)\\\\\\[/tex]
-3-y = 4*(-1)
-3 - y = -4
- y = - 4 + 3
-y = -1
Divide both sides by (-1)
y = 1

6 + 4w = 2w − 6
Solve for W
Answer:
W=-6
Step-by-step explanation:
6+4w=2w-6
Collect Terms
4w-2w=-6-6
2w=-12
now divide both sides by 2
2w/2=-12/2
w=-6
8a=4(a-9)
Show work I need help
Answer:
a = -9
Step-by-step explanation:
8a=4(a-9)
Divide each side by 4
8a/4=4(a-9)/4
2a = a-9
Subtract a from each side
2a-a = a-9-a
a = -9
Answer:
-9
Step-by-step explanation:
8a = 4(a-9)
Use the distributive property (Multiply 4 times a, and 4 times -9)
8a = 4a - 36
Bring the 4a to the other side
8a - 4a = -36
Add like terms
4a = -36
Divide both sides by 4 to get a by itself
a = -9

Findi the value of x
Answer:
By Pythagoras theorem ,
H^2 = P^2 + B^2
H^2 = 4^2 + 3^2
H^2 = 16 + 9
H^2 = 25
H = 5
therefore , value of x = 5
hope that helps uh..☺
Answer:
x = 5
Step-by-step explanation:
Since it's a right triangle, you can use Pythagorean Theorem.
[tex]a^2+b^2=c^2\\3^2+4^2=x^2\\9+16=x^2\\25=x^2\\5=x[/tex]

. Cathy is playing a game with a set of 52 cards. The cards are different
colors and each show a number.
• The probability of randomly selecting a black card is.
• The probability of randomly selecting a red card is.
If Cathy randomly selects a card, what is the probability that her card is
black OR red?
Answer:
something missing here... is this a regular deck of cards Hearts, spades, clubs , and diamonds ? 1/2 red and 1/2 black ... if so....
then.....
P(black) = .5
P(red) = .5
P(red or black) = 1 (100%)

find the HCF
eg. first expression = 4a -8
=4(a-2)
Answer:
Step-by-step explanation:
ab² + 2a²b + a³ = a(b² + 2ab + a²)
Here variable 'a' is common in all the terms. HCF = a
2) 2ab² = 2 * a * b *b
4a²b = 2 * 2 *a * a * b
6a³ = 2 * 3 * a * a * a
HCF = 2a
2ab² - 4a²b - 6a³ = 2a(b² - 2ab - 3a²)

Select all expressions that are equivalent to x2 - 4x - 32.
(x - 16)(x + 2)
(x + 2)(x - 16)
(x - 8)(x + 4)
(30+8)(x – 4)
(x + 4)(x - 8)
(x – 4)(x + 8)
Answer:
(x - 8)(x + 4)
(x + 4)(x - 8)
Step-by-step explanation:
(x - 16)(x + 2)
= x2 + 2x - 16x - 32
= x2 - 14x - 32
(x + 2)(x - 16)
= x2 - 16x + 2x - 32
= x2 - 14x - 32
(x - 8)(x + 4)
x - 8)(x + 4) = x2 + 4x - 8x - 32
x - 8)(x + 4) = x2 + 4x - 8x - 32 = x2 - 4x - 32
( 30 + x)(x - 4)
= 30x - 120 + x2 - 4x
= x2 + 26x - 120
(x + 4)(x - 8)
(x + 4)(x - 8) = x2 - 8x + 4x - 32
(x + 4)(x - 8) = x2 - 8x + 4x - 32 = x2 - 4x - 32
(x - 4)(x + 8)
= x2 + 8x - 4x - 32
= x2 + 4x - 32

barbara and jeff ate out for dinner the total came to &15.00. they left a 15% tip how much was the tip and the meal together?
Answer:
$17.25
Step-by-step explanation:
The tip is 15% of $15.00, or 0.15 * 15 = $2.25
We add that to the meal's cost, which is $15.00
15.00 + 2.25 = 17.25

w
5.2
Answer:
A rectangle has a height of 5 and a width of x² + 2
To find out:
Express the area of the emotive rectangle?
Formula used:
Area of rectangle = Length × Breadth.
Solutions:
Length = 5 and Breadth = x² + 2
We know that:
Area of rectangle = Length × Breadth.
Substitution the value of Length × Breadth.
= 5 × (x² + 2)
= 5x² + 10
Hence, the area of the emotive rectangle is 5x² + 10
Additional informational:
•Monomials: expressions with single terms are called monomials.
• Binomial: expressions with two terms are called binomials.
• Trinomial: expressions with 3 terms is called trinomial.
• Multinational: expression with Tu are mo terms are called Multinational.

Find the probability of “landing” in the shaded region of the figures below. Round your answer to the nearest hundredth.
Answer:
#4Area of rectangle:
A = lw = 10*20 = 200 m²Shaded area:
A = 2πr² = 2π(10/2)² = 157.079 m²Probability:
P = 157.079/200 ≈ 0.785 or 78.5%#5Area of bigger circle:
A = πr² = π(20)² = 1256.637 m²Shaded area:
A = π(10² - 5²) = 235.619 m²Probability:
P = 235.619/1256.637 ≈ 0.187 or 18.7%Answer:
4
We know that
Area of rectangle = lb
Area = 10(20)
Area = 200 m²
Shaded region = πr²
=> 2 × 22/7 × (10/2)²
=> 2 × 22/7 × 10/4
=> 157 m²
Probability = 157/200 = 78.5%
5.
Area of the biggest circle = πr²
= 22/7 × (20)²
= 1256.6
Area of shaded region
π(10² - 5²)
π(100 - 25)
3.14(75)
235.6
Probability = 235.6/1256.6 = 18.7%
