Is this congruent by SSS, SAS, AAS, ASA?
Answer:
Yes, congruent by SAS
Step-by-step explanation:
We already know two sides and two angles are congruent, and since the triangles share the same congruent side with an angle in between both pairs of congruent sides, then yes it is congruent by SAS.
Three numbers are in the ratio 3:4:5. If the sum of their cubes is 216000, find the largest of these three numbers.
Answer:
50
Step-by-step explanation:
Let the numbers be 3x, 4x, 5x
(3x)^3 + (4x)^3 + (5x)^3 = 216000
27x^3 + 64x^3 + 125x^3 = 216000
216x^3 = 216000
x^3 = 1000
x = 10
5x = 5(10) = 50
Answer: 50

x−4y=−7
−x+2y=3
A(1, 3)
B(1, 2)
C(-1, -3)
D(1, -3)
Answer:
B
Both systems can be sloved by susbituding (1,2)
Step-by-step explanation:
(1)- x−4y=−7
Substitute in the x and y values: 1 - 4 (2) = -7
Multiply the numbers : 1 - 8 = -7
Calculate the difference: -7 = -7
(2) - −x+2y=3
Substitute in the x and y values: -1 + 2 (2) = 3
Multiply the numbers : -1 + 4 = 3
Calculate the sum: 3 = 3
Given lines p and q are parallel, m<2 - (14x - 12), m<6 - (5y + 23), and m<8 - (8x + 27), solve for the values of x and y then solve for the measure of each angle
Answer:
x = 7.5
y = 14
m<1 = 87°
m<7 = 93°
Step-by-step explanation:
Given:
m<2 = (14x - 12),
m<6 = (5y + 23),
m<8 = (8x + 27)
m<2 + m<8 = 180° (consecutive exterior angles are supplementary)
(14x - 12) + (8x + 27) = 180 (substitution)
Solve for x
14x - 12 + 8x + 27 = 180
Collect like terms
22x + 15 = 180
Subtract 15 from each side
22x = 180 - 15
22x = 165
Divide both sides by 22
x = 7.5
m<2 = m<6 (corresponding angles are congruent)
(14x - 12) = (5y + 23) (substitution)
Plug in the value of x
14(7.5) - 12 = 5y + 23
105 - 12 = 5y + 23
93 = 5y + 23
Subtract 23 from each side
93 - 23 = 5y
70 = 5y
Divide both sides by 5
14 = y
y = 14
✅m<1 = m<8 (alternate exterior angles are congruent)
m<1 = (8x + 27) (substitution)
Plug in the value of x
m<1 = 8(7.5) + 27 = 87°
m<7 = m<2 (alternate exterior angles are congruent)
m<7 = (14x - 12) (substitution)
Plug in the value of x
m<7 = 14(7.5) - 12 = 93°

Jane invested her savings in two investment funds. The amount she invested in Fund A was $6000 less than the amount she invested in Fund B. Fund A returned a 8% profit and Fund B returned a 2% profit. How much did she invest in Fund B, if the total profit from the two funds together was $1220 ?
Answer:
Jane invested $37,000 in Fund B.
Step-by-step explanation:
Let;
IA = Amount invested in Fund A = $6,000
IB = Amount invested in Fund B = ?
PA = Amount of profit from Fund A = IA * 8% = $6,000 * 8% = $480
PB = Amount of profit from Fund B = IB * 2%
Therefore, we have:
Total profit = PA + PB = $1220 ........................ (1)
Substitute the relevant values into equation (1) and solve for IB, we have:
$480 + (IB * 2%) = $1220
IB * 2% = $1220 - $480
IB * 2% = 740
IB = 740 / 2%
IB = $37,000
Therefor, Jane invested $37,000 in Fund B.
using y=-6x what is the value of x if y=42
Answer:
Step-by-step explanation:
Y = - 6x
Putting value of 42
42 = - 6x
42/-6 = x
-7 = x
Answer:
x=-7
Step-by-step explanation:
y=-6x
y=42
use substitution
42=-6x
divide both sides by -6
x=-7

What is the equation of this line?
Answer:
y= -5/4x + 6
Step-by-step explanation:
y= mx + b
m= -5/4 (rise over run/slope)
b= 6 (y-intercept)
-I hope this helps have a great day!
Answer:
y = -5/4(x)+6
Step-by-step explanation:
to find the equation of this line, we must first find the slope
We can write the equation of this line y = mx + b where m is the slope and b is the y-intercept
m = (y2-y1)/(x2-x1)
m = (-4-6)/(8-0)
m = -10/8
m = -5/4
b is the y intercept which is at 6
So the equation of the line is y = -5/4(x)+6

D) 17
Answer:
45/3 or 15 simplified
Step-by-step explanation:
so b. 15
Answer:
Quick answer is B
Step-by-step explanation:
Use the rise over run method Y2-Y1 over X2-X1 and get your fraction. Divide your fraction to get your number and you get 15. Your equation should be simalar to this 75-30 over 5-2= 45 over 3 which is equal to 15.
Which shows the best use of the associative and commutative properties to make simplifying -1/3-10+7+2/3+5 easier

Find the value of x for which r || s.
Then find m<1 and m<2.
m<1 = 79- x
m<2 = 94- 2x
< means angle
Answer:
x=15
Step-by-step explanation:
79-15=64
94-30=64
The value of x for which r || s will be 15.
What are Parallel lines?
Parallel lines are those lines that are equidistance from each other and never intersect each other.
Given that;
Lines r and s are parallel to each other.
m ∠1 = 79 - x
m ∠2 = 94 - 2x
Since, Two lines r and s are parallel to each other.
Then, By definition of alternate angles of parallel lines;
m ∠1 = m ∠2
Now, Substitute the given values we get;
m ∠1 = m ∠2
79 - x = 94 - 2x
Subtract 79 both side,
79 - x - 79 = 94 - 2x - 79
- x = 15 - 2x
Add 2x both side,
- x + 2x = 15 - 2x + 2x
x = 15
Thus, The value of x is 15 for which r || s.
