Answer:
7.8 cm and 25.3 cm
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
?² + 7² = 10.5²
?² + 49 = 110.25 ( subtract 49 from both sides )
?² = 61.25 ( take the square root of both sides )
? = [tex]\sqrt{61.25}[/tex] ≈ 7.8 cm ( to 1 dec. place )
Then
P = 10.5 + 7 + 7.8 = 25.3 cm

Estimate the solution to the system of equations.
y=−2x−5
y=2x−2
Answer:
(-3/4, -7/2)
Step-by-step explanation:
y= −2x − 5
y= 2x − 2
2y = -7
y = -7/2
y= 2x − 2
-7/2 = 2x - 2
2x = -3/2
x = -3/4
(x,y) = (-3/4, -7/2)
Answer:
-3/4 or -7/2

Find the x- and y-intercepts of the graph of -x +y = 8. State your answers as
whole numbers or as improper fractions in simplest form.
Given:
The equation is
[tex]-x+y=8[/tex]
To find:
The x- and y-intercepts.
Solution:
We have,
[tex]-x+y=8[/tex]
Put x=0 in the given equation to find the y-intercept.
[tex]-(0)+y=8[/tex]
[tex]y=8[/tex]
Put y=0 in the given equation to find the x-intercept.
[tex]-x+(0)=8[/tex]
[tex]-x=8[/tex]
[tex]x=-8[/tex]
Therefore, the x-intercept is -8 and the y-intercept is 8.

O g(x) = -4(2)
O g(x) = 4(2)**
O g() = -43)
O g(x) = 4(1)
000
Answer: Correct answer is C -I just took the test
we have the function f(x) = 4(1/2)x, and we want to reflex it over the x-axis.
you can see in the graph that the reflex over this axis changes the sign of f(x) in all the points (where f(0) = 4, g(0) = -4, f(1) = 2, g(1) = -2, and so on), then the reflex, g(x) is equal to -f(x)
now we have:
g(x) = -f(x) = - 4(1/2)x
then the right answer is the third option:
g(x) = -4(1/2)x

Write an equation for a line using (-3,8) and (-2,2) use either point slope of slope intercept
Determine the equation of the line passing through the points A(–1, 6) and B(2, 4).
Answer:
y = -2/3x + 5 1/3
Step-by-step explanation:
Find the slope:
4 - 6 / 2 - (-1) = -2/3
Put it in point-slope form:
y - 6 = -2/3(x + 1)
rearrange:
y - 6 = -2/3x - 2/3
y = -2/3x + 5 1/3

On a coordinate plane, point B(–6, 1) is translated to B prime(–3, –2). Indira uses these steps to find a rule to describe the translation.
Step 1 Substitute the original coordinates and the translated coordinates into (x, y) right-arrow (x + a, y + b):
B (negative 6, 1) right-arrow B prime (negative 6 + a, 1 + b) = B prime (negative 3, negative 2)
Step 2
Write two equations:
Negative 6 + a = negative 2. 1 + b = negative 3.
Step 3
Solve each equation:
Negative 6 + a = negative 2. a = negative 2 + 6. a = 4. 1 + b = 3. b = negative 3 minus 1. b = negative 4.
Step 4
Write the translation rule:
(x, y) right-arrow (x + 4, y minus 4)
Which corrects Indira’s first error?
Indira should have substituted B (negative 6, 1) right-arrow B prime (negative 3 + a, negative 2 + b) = B prime (negative 6, 1) in Step 1.
Indira should have written the equations Negative 6 + a = negative 3 and 1 + b = negative 2 in Step 2.
Indira should have solved the equations to find that a = negative 8 and b = negative 2 in Step 3.
Indira should have written the translation rule (x, y) right-arrow (x minus 4, y + 4) in Step 4.

Scientists are examining two different strains of a particular bacteria. The length of one strain of the bacteria measures 0.000000143 mm, while the length of the second strain measures 0.0000000937 mm. How much larger is the first strain than the second?
Answer:
1.53 times
Step-by-step explanation:
Scientists are examining two different strains of a particular bacteria. The length of one strain of the bacteria measures 0.000000143 mm, while the length of the second strain measures 0.0000000937 mm. How much larger is the first strain than the second?
We would have:
First strain : Second strain
0.000000143 mm : 0.0000000937 mm
How much larger is the first strain than the second?
We divide both by the length of the second strain
0.000000143/0.0000000937 : 0.0000000937 / 0.0000000937
1.52614727855 times
Approximately = 1.53 times
