Can someone help me with this please?
Answer:
the function is linear
Step-by-step explanation:
now you figure this out in many ways,
but the easiest is to plot the points on a Cartesian x-y plane, rule a line through the points,if it's in a straight line then its linear if it's a curve its cubic
from the question, after plotting your points.ie (-9,-2),(-5,-7),(-1,-12),(3-17)
we get a straight line pointing downwards.
I hope this is convenient enough

Under her cell phone plan, Morgan pays a flat cost of $55.50 per month and $4 per gigabyte. She wants to keep her bill at $71.90 per month. How many gigabytes of data can she use while staying within her budget?
Answer:
4.1
Step-by-step explanation:
You would first subtract 55.50 from 71.90 which leaves you with 16.4,
Then you would divide 16.4 by 4 to find how many gigabytes she could use which gives you 4.1

Step-by-step explanation:
a. What is the circumference of the
largest circle that can be cut from a
square measuring 30 cm on a side?
Use 3.14 for Pie
b. What percent of the perimeter of the
square is the circumference of the
circle?
Answer:
a) 94.2 cm
b) 78.5%
Step-by-step explanation:
a) since the square side = 30 cm
it means the diameter = 30 cm
then circumference of the largest circle that can be cut = 3.14×30 = 94.2 cm
b) the perimeter of the square = 30×4 = 120
94.2 for 120
x% for 100%
x = (100×94.2)/120 = 9420/120 = 942/12 = 78.5%

2) m<D = m<ADB : If two angles have the same measure, then they are equal.
3) <D congruent to <ADB : if two angle are equal, then they are congruent.
4) <D, <ADB are alternate interior angles: assumed from diagram
5) CD // AB : if alternate interior angles are congruent, then the 2 lines cut by a transversal are //.
6) 130 + 50 = 180 : addition property of equality
7) m<E, m<BAE are supplements : if the sum of two angles equal to 180, then they are supplements.
8) <E, <BAE are same-side interior angles : assumed from diagram
9) EF // AB : if same-side interior angles are supplements, then the 2 lines cut by a transversal are //.
10) CD // EF : if two lines are // to the same line, then they are //.

Can you please help me solve for x for this triangle please!!
Answer:
See below, please!
Step-by-step explanation:
Since this triangle is a right triangle, the two acute angles are always going to be complementary (adding up to 90 degrees). So we can set up an equation: 2x+3x+5=90. Solve this and we get x=17.

A new car is purchased for 23900 dollars. The value of the car depreciates at 9.25% per year. To the nearest tenth of a year, how long will it be until the value of the car is 6000 dollars?
9514 1404 393
Answer:
14.2 years
Step-by-step explanation:
The value is described by the exponential function ...
y = (initial value)·(decay factor)^x
where y is the value after x years.
The decay factor is (1 - annual depreciation) = 1 - 0.0925 = 0.9075, so we want to find x when ...
6000 = 23900·0.9075^x
6000/23900 = 0.9075^x . . . . . . . . . . . . . . divide by 23900
log(6000/23900) = x·log(0.9075) . . . . . . . take logarithms
x = log(6000/23900)/log(0.9075) ≈ 14.2396
It will be about 14.2 years until the value of the car is $6000.

. Jacob and Sadie each got ahead on their skills practices. Jacob completed twelve fewer problems than twice the number Sadie completed. They completed a total of 127 problems. Which system of equations models this situation if Jacob completed j problems & Sadie completed s problems? A) j + s = 127
Answer:
2s-12=j
S+J=127
Step-by-step explanation:
ok so firstly you are going to have 2 problems. Jacob has 12 fewer than 2x Sadie's so it will look like this, 2s-12=j
. 2x Sadie's minus 12 will give you Jacobs. and then it tells you that together they have 127 completed so S+J=127

the side of a square is 8√2 what will be its diagonal
Answer ASAP
Answer:
16
Step-by-step explanation:
You can use the pythagorean theorem:
[tex]a^{2}+b^{2}=c^{2}[/tex], here seeing as we know already know two sides here as all sides are congruent with squares and there has to be right angles for it to be a square we can do so by cutting the square in half for the diagonal and to get a right triangle.
And from there we just use it:
[tex]8\sqrt{2}^{2} + 8\sqrt{2}^{2} = c^{2}[/tex]
[tex]\sqrt{128}^{2} + \sqrt{128}^{2} = c^{2}[/tex]
[tex]128 + 128 = c^2[/tex]
[tex]256 = c^2[/tex]
[tex]\sqrt{c}^2 = \sqrt{256}[/tex]
[tex]c = 16[/tex]
Meaning that the diagonal is 16.

Answer:
x = 4 units
Step-by-step explanation:
2/z = z/6
z² = 12
z = 2√3
using the Pythagorean theorem:
x² = 12 + 2²
x² = 16
x = 4
Based on the definition of an equilateral triangle, the value of x is: B. 4 units.
What is an Equilateral Triangle?An equilateral triangle is a triangle whose three sides have the same length, and all three interior angles are equal to 60 degrees each.If triangle MRN is created when an equilateral triangle is folded in half, therefore:
x = 1/2 of (NM)
x = 1/2(6 + 2)
x = 1/2(8)
x = 4 units
Therefore, based on the definition of an equilateral triangle, the value of x is: B. 4 units.

Terrence finished a word search in the time it took Frank. Charlotte finished the word search in the time it took Terrence. Frank finished the word search in 32 minutes. How long did it take Charlotte to finish the word search?
Answer:
Charlotte finished the word search in 16 minutes
Step-by-step explanation:
Terrence finished a word search in 3/4 the time it took frank. charlotte finished the word search in2/3 the time it took terrence. Frank finished the word search in 32 min. how long did it take charlotte to finish the word search
Frank finished the word search in 32 min
Terrence finished a word search in 3/4 the time it took frank
Terrence = 3/4 of 32 min
= 3/4 × 32 minutes
= (3×32)/4
= 96/4
= 24 minutes
Terrence finished a word search in 24 minutes
Charlotte finished the word search in 2/3 the time it took Terrence
Charlotte = 2/3 of 24 minutes
= 2/3 × 24
= (2×24)/3
= 48/3
= 16 minutes
Charlotte finished the word search in 16 minutes
Sakal and Roy each have a sack of 50 apples. All apples are either red or green. If Sakal has three times as many red apples as Roy does and half as many green apples as Roy does, how many red apples does Sakal have?
Answer:
Step-by-step explanation:
Sakal and Roy each have a sack of 50 apples.
All apples are either red or green.
Sakal = x
Roy = y
If Sakal has three times as many red apples as Roy does
x = 3y
and half as many green apples as Roy does,
x = 1/2y
how many red apples does Sakal have?
