Answer:
y = 5 and x = 2
Step-by-step explanation:
Since we have x = -3y + 17, we're going to substitute this equation into the x-value in the second equation.
2(-3y + 17) - y = -1
Multiply the 2 with the terms within the parentheses.
-6y + 34 - y = -1
Add the y values.
-7y + 34 = -1
Subtract 34 from both sides.
-7y = 35
Divide each side by -7.
y = 5
Now that we know the value of y, we can substitute 5 for the y-value in the first equation.
x = -3(5) + 17
Multiply.
x = -15 + 17
Add the two terms together.
x = 2

Which triangle is similar to △ABC if sin(A) = One-fourth, cos(A) = StartFraction StartRoot 15 EndRoot Over 4 EndFraction, and tan(A) = StartFraction 1 Over StartRoot 15 EndRoot EndFraction?
Answer:
ΔXYZ
Step-by-step explanation:
Trigonometric identities are equations which are true for right angled triangles. They are:
sin(A) = opposite / hypotenuse, cos(A) = adjacent / hypotenuse, tan(A) = opposite / adjacent.
Given triangle ABC with ∠A with side BC opposite to the angle, ∠B with side AC opposite to the angle, ∠C with side AB opposite to the angle.
sin(A) = opposite / hypotenuse = BC / AC = 1/4
BC = 1, AC = 4
cos(A) = adjacent / hypotenuse = AB / AC = √15 / 4
AB = √15
tan(A) = opposite / adjacent = BC / AB = 1 / √15
Two triangles are said to be similar if the ratio of their corresponding sides are in the same proportion.
ΔXYZ and ΔABC are similar because the ratio of their corresponding sides are in the same proportion.
For adjacent side; XZ / AB = 6√15 / √15 = 6
For opposite side; YZ / BC = 6/1 = 6
For hypotenuse side; XY / AC = 24 / 4 = 6
Answer:
D. ΔXYZ

A. 2 cm
B. 2√2 cm
C. 4 cm
D. 4√2 cm
Answer:
.D. 4√2 cm
Step-by-step explanation:
With reference angle 45°
base (b) = 4 cm
hypotenuse (h) = AC
Now
Cos 45° = b /h
1/√2 = 4 / AC
AC = 4√2 cm

If B = 1 - 2s^2 – s and C = 3 + 5s², find an expression that equals 3B + C in
standard form.
Answer: -s² - 3s + 6
Step-by-step explanation:
b = 1 - 2s² - s
c = 3 + 5s²
Substitute
3b + c
3 (1 - 2s² - s) + 3 + 5s²
3 - 6s² - 3s + 3 + 5s²
Put like terms together
-6s² + 5s² - 3s + 3 + 3
-s² - 3s + 6

Determine how much you would receive in return for a 8 month, $500 loan to a friend if you charged the 3% annual interest. Show your work.
i think its $4,120
I hope this helps
Answer:
$15 dollars
Step-by-step explanation:
use the whole part percent to work out answer
so its x/500 = 3/100 cross multiple 500x3= 1500 then you divide 1500 by 100 which equals 15
it looks like this kinda its hard to put on here
x = 3
500 100
so thats where u cross multiply the 500*3=1500 then divide 1500/100= 15

The circle below has a radius of 3 units . Find the area of the circle. Use 3.14 for π.
A=πr2=π×r×r
i well give u 10 points
Answer:
28.26 units
Step-by-step explanation:
We know the radius of the circle is 3 units, so we'll end up plugging that into the formula.
A = π(3^2) or A = π * 3 * 3
When you substitute pi for 3.14, you'll end up getting 28.26 units.

Last night, Roberto spent 90 minutes doing homework, infinity symbol hour reading, and 540 seconds making his lunch for the next day. How many more minutes did Roberto spend doing homework than he did reading and making his lunch?
A) 50 minutes
B) 49 minutes
C) 41 minutes
If you steal the points, ill report you (❁*ᵕ*)︻╦╤─
Answer:
C. 41 minutes
Step-by-step explanation:
First, we have to turn 540 seconds into minutes by dividing it by 60
540 ÷ 60 = 9
So 50 - 9 = 41
So Roberto spent 41 more minutes reading than he did making his lunch
