Step-by-step explanation:
It was reflected across the x axis, resized and moved in x and y directions, but since the shape ABCD is symmetrical across the y axis, a reflection across y axis won’t change anything!
Find the slope of this line, show work -15 - x=-5y
equation of the line formula : y = mx + c
════════ ∘◦❁◦∘ ════════
Answer : ⅕════════════════════
-15 - x = -5y
-15 -1x = -5y
(-15 : -5) - (1:-5x) = y
3 - (-⅕x) = y
3 + ⅕x = y
3 + ⅕x = y
y = ⅕x + 3
#So m (slope) is ⅕
════════════════════
Step-by-step explanation:
Given.
- 15-x = - 5y
5y = x + 15
y = ( x + 15) 5
y = x / 5 + 3
comparing the given equation with y = mx + c Then
Slope (m) = 1/5
Hope it will help :)
60% of a number is 54. what is 50% of the same ?
Answer:
The answer is 45.
Step-by-step explanation:
60% of a number is 54, find the original number
54 ÷ 60%
= 54 ÷ 60/100
= 54 * 100/60
= 90
50% of 90 is
90 * 50%
= 90 * 50/100
= 90 * 1/2
= 45
Pls help me with math ASAP
Answer:
y = 5/2x - 5
Step-by-step explanation:
y-int = -5
slope = 5/2
rise/run
alright my friend i've gotta go but i think you can solve these on your own.
just use the number that's on the Y vertical line to find y-int
and then use 2 points and count up to find the rise and then count across to fine thet run.
use the formula y=mx+b
good luck my friend <3
Answer:
Step-by-step explanation:
(0,-5) (4,5)
(5+5)/(4-0)= 10/4 = 5/2
y + 5 = 5/2(x - 0)
y + 5 = 5/2x - 0
y = 5/2x - 5
Solve for r. Show your work!
12 =R– (34 – 2)
Helpppp!!
Answer:
r = 44
Step-by-step explanation:
12 = r - (34 - 2)
Solve for r
___________
To solve, we need to isolate r.
Distribute the negative sign with the numbers within the parenthesis :
12 = r - 34 + 2
Add like terms :
12 = r - 32
Add 32 to both sides :
44 = r
r = 44
Answer:
we are just going to start by using pemdas and making it easier to solve
Step-by-step explanation:
12=R-(34-2)
12= R-32
add 32 to both sides
32+12=R
so R=44
Hope this helps :)
Fossils show that
insects were much larger around 300 million
years ago than they are today. The table at
the right shows some of the wing lengths
found in fossils. How much longer was the
wing length of the dragonfly than the wing
length of the fly?
Answer:
The wing of the dragonfly was 9.65 cm longer than that of the fly, 102% larger in percentage terms.
Step-by-step explanation:
Since the length of the wing of the old dragonfly was 19.5 cm, while the length of the wing of a common fly is 9.85 cm, to determine how long the dragonfly's wing was compared to that of the fly, the following must be done calculations:
19.5 - 9.85 = X
9.65 = X
Thus, the wing of the dragonfly was 9.65 cm longer than that of the fly. In turn, in terms of percentages, the result is the following:
9.65 = 100
19.5 = X
19.5 x 100 / 9.65 = X
1950 / 9.65 = X
202 = X
Thus, in percentage terms, the dragonfly's wing was 102% larger than that of the current fly.

Meliyah is an administrative assistant. She earns a weekly salary of $412.00. She applied and was hired for an administrative specialist position. Meliyah’s annual salary in her new position will be $24,388.00. How much will Meliyah’s weekly salary be in her new position?
Answer:
[tex]Weekly\ Salary = \$469[/tex]
Step-by-step explanation:
Given
[tex]Current = \$412.00[/tex] --- weekly
[tex]NEw = \$24.388.00[/tex] --- annually
Required
Determine her new weekly salary
To do this, we simply divide her salary by 52 (the number of weeks).
So, we have:
[tex]Weekly\ Salary = \frac{\$24,388.00}{52}[/tex]
[tex]Weekly\ Salary = \$469[/tex]
Her weekly salary is $469
HELP ASAP! I’m very confused and need help! Thank you!
if right answer good review
Answer:
Top left: a is negative and p is positive
Step-by-step explanation:
The formula y = ax + p is referring to the formula y = mx + b where m is the slope and b is the y-intercept.
Since the line is going down, the slope is negative-- a is negative.
Since the line crosses the y-axis above the origin, the y-intercept is positive-- p is positive.
Answer:
a is negative and p is positive
Step-by-step explanation:
The equation y = ax + p is written in slope-intercept form, where a is the slope and p is the y-intercept.
When a slope is negative, the line goes down the further right it goes.
The line on the graph lowers as it moves right, which means that the slope(a) is negative.
The line intercepts the y-axis above the origin, which means that it must be positive.

I'm going to solve this step by step:
Given: w=x(v_2 - v_1)
w/x=v_2-v_1
v_2=w/x+v_1
[tex] \tt \dashrightarrow w = x(v_2 - v_1) [/tex]
[tex] \tt \dashrightarrow \dfrac{w}{x} = v_2 - v_1[/tex]
[tex] \tt \dashrightarrow \dfrac{w}{x} + v_1= v_2[/tex]
[tex] \tt \dashrightarrow v_2 = \dfrac{w}{x} + v_1[/tex]
[tex] \large \underline{\boxed{\bf{v_2 = \dfrac{w}{x} + v_1}}}[/tex]

Estimate 34,182-18,717 by first rounding each number to the nearest thousand.
Answer:
15,000
Step-by-step explanation:
First, round both the numbers:
34,182 rounds down to 34,000
18,717 rounds up to 19,000
Subtract you're two rounded numbers
34,000 - 19,000 = 15,000
Kristin wants to buy a pair of jeans that cost $35 and are on sale
20% off. She is also buying two T-shirts at a full price of $9.99 each.
She must pay 6.5% sales tax. How much will she pay for the clothes
Answer:
$51.10
Step-by-step explanation:
First, find 20% of $35, then add the sale price of the jeans and the two t-shirts. Take the total and find the sales tax and add that onto the cost.
100 - 20 = 80 If you multiply the jeans by 80% it gives you the price for the jeans saving you from having to subtract the discount from the original price.
35 * 0.80 = $28.00 jeans 28.00 47.98
9.99 + 3.12
+ 9.99 $51.10
47.98
X 0.065
$3.12

This question is kind of confusing to me. Can I get some help?
Answer:
b. [tex]\frac{1}{3}[/tex]
Step-by-step explanation:
The scale factor is the number by which one must multiply all sides in a triangle such that its sides are the same as another triangle. This only works in similar triangles (triangles where all of the angles between them are congruent or have the same measures).

If a square has a side of (3x+5), what is its perimeter?”
O
a.6x + 10
b.3x + 15
c.123 + 5
d.123 + 20
Answer:
Step-by-step explanation:
The perimeter of a square is four times a side. We are told a side equals 3x+5 so
P=4S
P=4(3x+5)
P=12x+20
