2(2/5) divided 2(-1/5)
we do PEMDAS meaning parenthesis first
2(2/5) = 4/5(calculator)
or
2/1x2/5=4/5
now
2/1x-1/5=-2/5
now we do division
4/5/-2/5 we get -2

At Sally's market the ratio of apples to oranges is 4 to 7. If there are 28 oranges at her market
then how many apples are there?
Answer:
16 apples
Step-by-step explanation:
If the original ratio is 4:7.
Then we multiply both numbers by 4. Since 7 x 4 is 28.
So now you have (4x4):(7x4)
Your final ratio is 16 apples : 28 oranges

x is another leg next to 6.
10 is the hypotenuse.
a^2 + b^2 = c^2
a & b are legs and c is the hypotenuse.
x^2 + 6^2 = 10^2
x^2 + 36 = 100
x^2 = 100 - 36
x^2 = 64
√x^2 = √64
x = 8

The given reflection transformation is a rigid transformation, such that the dimensions are preserved
The statements that are true about the image of triangle ABC following a reflection Bout the the line y = 2·a are;
AB = RSΔABC ≅ ΔRSTm∠BAC ≅ m∠SRTReasons:
The given parameters are;
Triangle ΔABC is reflected across the line y = 2·x
Given that a reflection is a rigid transformation, we have;
The distance between two points on a preimage is the same as the distance between the corresponding points on the image;
Therefore;
ΔABC is congruent to ΔRST by Side-Side-Side SSS, rule of congruency, such that we have;
AB ≅ RS, BC ≅ ST, and AC ≅ RT
m∠BAC ≅ m∠SRT
m∠BCA ≅ m∠STR

The equation y=2x+3 represents the cost y (in dollars) of mailing a package that weighs x pounds. a. Graph the equation. b. Using the graph, which is the best estimate for the cost to mail the package?
a. Graph the equation.
b. Using the graph, which is the best estimate for the cost to mail the package?
the packedge is 1.126 lb
c. Use the equation to find how much it costs to mail the package.
Answer:
B. Slightly more than $5
Step-by-step explanation:
y = 2x + 3
Firstly we check variables to make sure we understand.
y = dollars
x = pounds
On the scale, it says 1.126 lb. Which means 1.126 pounds.
And so, x = 1.126
y = 2x + 3
y = 2(1.126) + 3
y = 2.252 + 3
y = 2.252
The graph for part a and park b. It is underneath. I wrote 1.1, because it is rounded down from 1.126 lb, which is part b. The one with one line and no dots is part a.

Find the length of the third side. If necessary, round your the nearest tenth.
Answer:
24
Step-by-step explanation:
Use Pythagorean theorem,
base² + altitude² = hypotenuse²
7² + altitude² = 25²
altitude² = 25² - 7²
= 625 - 49
= 576
altitude = √576
altitude = 24
_________
[tex] \: [/tex]
b² = c² - a²
b² = 25² - 7²
b² = 625 - 49
b² = 576
b = √576

Answer:
9
Step-by-step explanation:
2(m+2) = 22
Using the distributive property, you can multiply the 2 to both the "m" term and the "2".
2m + 2*2 = 22
2m + 4 = 22
Then you isolate the variable and solve.
2m = 22 - 4
2m = 18
m = 9
2(m + 2) = 22
2(m) + 2(2) = 22
2m + 4 = 22
2m = 22 - 4
2m = 18
2m / 2 = 18 / 2
m = 9
To distribute the 2 to each term inside the parentheses means to multiply the 2 by both terms in the parentheses so
2(m + 2) means (2 × m) + (2 × 4)

Write an equation of the parabola in vertex form. (-2, 6) (-1, 3)
An equation of the parabola is y=
The equation of the parabola is y = -3(x + 2)^2 + 6
How to determine the parabola equation?From the graph, we have:
Vertex, (h,k) = (-2,6)Point (x,y) = (-1,3)A parabola is represented as:
y = a(x - h)^2 + k
Substitute (h,k) = (-2,6)
y = a(x + 2)^2 + 6
Substitute (x,y) = (-1,3)
3 = a(-1 + 2)^2 + 6
Evaluate
3 = a + 6
Subtract 6 from both sides
a = -3
Substitute a = -3 in y = a(x + 2)^2 + 6
y = -3(x + 2)^2 + 6
Hence, the equation of the parabola is y = -3(x + 2)^2 + 6
