Answer:
x=1 y=1
Step-by-step explanation:
You want to chose either x or y to cancel out of both equations. I chose y, so I multiplied the entire equation of 3x-y=2 by 2 to get 6x-2y=4
6x-2y=4
x+2y=3
The -2y and 2y cancel each other out, the 6x and x can be added, and the 4 and 3 can be added.
7x=7
x=1
Now that we know x=1, plug in x to one of the original equation.
1+2y=3
2y=2
y=1
Classify the triangle as acute, obtuse, or right based on the given side
lengths. *
8, 17, 19
Acute
Obtuse
Right
Answer:
Obtuse
Step-by-step explanation:
Pythagorean thm:
a² + b² = c²
8² + 17² = 19²
64 + 289 = 361
353 = 361
Since c (the hypotenuse) is bigger than the legs combined, the triangle is obtuse.

A geology teacher takes her class on an annual field trip to analyze rock samples. They use randomized sets of
coordinates to select samples from two regions.
Suppose they examine a sample of 70 rocks from region A, which is composed of 15% igneous rock. Then they
examine a sample of 60 rocks from region B, which is composed of 20% igneous rock. Then they look at the
difference between the sample proportions (PA - B).
What are the mean and standard deviation of the sampling distribution of pA - PB?

The skating rink charges $0.75 to rent skates and $1.25 per hour to skate. Which equation
can be used to find the number of hours (h) someone skated if he or she was charged
$4.50?
a) 0.75 + 1.25 = 4.50
b) h(0.75 + 1.25) = 4.50
c) 0.75 + 1.25h = 4.50
d) 0.75h + 1.25 = 4.50
Answer:
C.
It can be read as...
".75 was charged for skates, and 1.25 was charged per hour for a total of 4.50."
No other answer choice has this. A does not have the variable h, B includes .75 which is NOT charged per hour, as well as D.
I hope this helps you!

Step-by-step explanation:
given the circumference of circle b is 85 ft . what is the arc lenght of arc ADC?and the lenght of arc Ac
Answer:
Length of arc AC = 10.6 ft
Length of arc ADC = 73.4 ft
Step-by-step explanation:
θ = 45°
Circumference = 85 ft
✔️First, find the radius:
Circumference of a circle = 2πr
Thus:
85 = 2πr
Solve for r
Use 3.14 as π
Divide both sides by 2π
85/2π = r
85/2*3.14 = r
85/6.28 = r
r = 13.5350318 ≈ 13.5 ft (nearest tenth)
✔️Find length of arc ADC:
Length of arc = θ/360 × Circumference of the circle
θ = 360 - 45° = 315°
Circumference = 85 ft
Plug in the values
Length of arc ADC = 315/360 × 85
= 74.375 ≈ 73.4 ft (nearest tenth)
✔️Find length of arc AD:
Length of arc = θ/360 × Circumference of the circle
θ = 45°
Circumference = 85 ft
Plug in the values
Length of arc AC = 45/360 × 85
= 10.625 ≈ 10.6 ft (nearest tenth)

If 10 miles≈16 km, about how many miles would be equal to 92 km? Show how you decided.
Answer:
57.5 miles
Step-by-step explanation:
10 mi : 16 km

(10)(92) = (16)(x)
920 = 16x
57.5 = x
surface area of a pyramid
WILL GIVE BRAINLIEST TO FIRST TO ANSWER CORRECTLY
Find the surface area of the pyramid. Round to the nearest tenth if necessary.
12.25 in.
15.75 in.
15.75 in.
in^2 = ?
Answer:
633.9 in.²
Step-by-step explanation:
Surface Area = Base Area + ½(Perimeter of Base)(slant height)
Base area = s² = 15.75² = 248.0625 in.²
Perimeter = 4(15.75) = 63 in.
Slant height = 12.25 in.
Surface area = 248.0625 + ½(63)(12.25)
= 633.9375 ≈ 633.9 in.² (nearest tenth)

2.1.1 Taxable income.
2.1.2 Tax rebates.
2.1.3 Tax threshold.
Answer:
Taxable income:
Taxable income includes wages, salaries, bonuses, and tips, as well as investment income and various types of unearned income. ... Taxable income also includes earnings generated from appreciated assets that have been sold during the year and from dividends and interest income.
Tax rebates:
A tax rebate (or tax refund) is money you reclaim from HMRC if you've paid too much tax. Travel tax refunds are a great example. If you're paying your own way to get to temporary workplaces, you can claim back some tax on your travel expenses.
Tax threshold:
The tax threshold is the amount of income below which you do not pay any income tax. The filing threshold is the income amount below which you do not have to file a tax return to Sars.
How do you write an equation in slope-intercept form for the line through the given points (8, 10) and (14, 13)
Answer:
y=1/2x+6
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(13-10)/(14-8)
m=3/6
simplify
m=1/2
y-y1=m(x-x1)
y-10=1/2(x-8)
y=1/2x-8/2+10
y=1/2x-4+10
y=1/2x+6

Using the Zero Factor Property, solve (2x + 1)(x - 6) = 0.
Answer:
1 2/3 or 1.67
Step-by-step explanation:
(2x+1)+(x-6)=0
Remove parenthesis.
2x+1+x-6=0
Rearrange to make life temporarily easier.
2x+x+1-6=0
Now combine like terms.
3x-5=0
Add 5 to cancel it out.
3x-5=0
+5 +5
3x=5
Divide 3 from both sides to cancel that out.
3x=5
/3 /3
x=5/3 or 1 2/3
So the answer is 1 2/3 or 1.67

9514 1404 393
Answer:
D. y = -1/3x
Step-by-step explanation:
The line through the origin means the equation will be a proportion of the form y = kx. (You can also see this by looking at the answer choices.) The value of k is ...
k = y/x . . . . . divide the above equation by x
For the given point (x, y) = (-3, 1), the value of k can be seen to be ...
k = 1/-3 = -1/3
Then the equation for the line is ...
y = -1/3x . . . . matches D

Answer:
m<ADC= 180-m<ABC or m<ABC=180-m<ADC
Step-by-step explanation:
Firstly, we need to establish that trapezoid ABCD is an isosceles trapezoid. By doing so, we know that angles opposite one another in an isoseles trapezoid are supplementary. As a result, m<ACD+m<ABC= 180. We can now solve for angle ACD or ABC.

On the right side, the numbers get larger by adding three each time. On the left side, the numbers get larger by adding 4 each time. It would be the same for any other pair of numbers when you add 4 to the left, and 3 to the right. For instance, the next pair would be (25 , 21). 25 would be the X value, and 21 would be the Y value.
