Step-by-step explanation:
Solve the system by substitution
7x-6y=16 (1)
y=-5
Show step by step
Answer:
7x - 6y = 16
y = (-5)
using substitution method
7x - 6(-5) = 16
7x +30 = 16
7x = 16 - 30
7x = 14
x = 14/7
x= 2

Answer:
Expression: [tex] \frac{40}{y - 16} [/tex]
When y = 20, the value of the expression is 10.
Step-by-step explanation:
The expression for the phrase "difference of a number, y, and 16" is (y - 16).
Therefore, the quotient of 40 and the "difference of a number, y, and 16" would be written as:
[tex] \frac{40}{y - 16} [/tex]
Let's evaluate the expression when y = 20.
Substitute y = 20 into [tex] \frac{40}{y - 16} [/tex].
Thus:
[tex] \frac{40}{20 - 16} [/tex]
[tex] = \frac{40}{4} = 10 [/tex]

y − 18 = 6(2 − 3y + 10) + y
Solve for y
Answer: y = 5
Step-by-step explanation:
Let's solve your equation step-by-step.
y−18=6(2−3y+10)+y
Step 1: Simplify both sides of the equation.
y−18=6(2−3y+10)+y
y+−18=(6)(2)+(6)(−3y)+(6)(10)+y(Distribute)
y+−18=12+−18y+60+y
y−18=(−18y+y)+(12+60)(Combine Like Terms)
y−18=−17y+72
y−18=−17y+72
Step 2: Add 17y to both sides.
y−18+17y=−17y+72+17y
18y−18=72
Step 3: Add 18 to both sides.
18y−18+18=72+18
18y=90
Step 4: Divide both sides by 18.
18y 90
18 = 18
y = 5

Triangles A B C, D E F, G H I, and J K L are shown. Angles A C B, D F E, H I G, and K L J are right angles. The length of side A C is 14 and the length of side C B is 20. The length of side E F is 8 and the length of F E is 10. The length of H I is 15 and the length of I G is 12. The length of K L is 10 and the length of L J is 7. The lengths of the hypotenuses are not given. Which pairs of triangles are similar? Check all that apply. △ABC ~ △DEF △DEF ~ △GHI △GHI ~ △ABC △GHI ~ △JKL △JKL ~ △ABC
Answer:
B) △DEF ~ △GHI
E) △JKL ~ △ABC
Step-by-step explanation:
i just did the assignment
The pairs of triangles are similar
△DEF ~ △GHI and △JKL ~ △ABC.
What is similarity ?If two triangles have an equal number of corresponding sides and an equal number of corresponding angles, then they are comparable. Similar figures are described as items with the same shape but varying sizes, such as two or more figures.
Given:
AC = 14
BC = 20
DF = 8
FE= 10
HI = 15
IG = 12
KL = 10
LJ = 7
As, In Right Triangle we can use Pythagoras theorem
AB = √14²+ 20² = 24.41
DE= √8²+10²= 12.8
HG= √15²+ 12² = 19.2
KJ= √10² + 7² = 12.2
Then, from the ratio of Corresponding sides we get
△DEF ~ △GHI and △JKL ~ △ABC.

factor the following expression[x squared minus x minus 12]
x2-x-12
Answer:
[tex]x^2-x-12=(x-4)(x+3)[/tex]
Step-by-step explanation:
Factoring a Trinomial
A trinomial is expressed in the form
[tex]ax^2+bx+c[/tex]
Where a,b, and c are real constants.
Some trinomials can be factored as the product of binomials with real coefficients, while others cannot.
If possible, factoring can be done in several ways:
Factoring out the GCF. The sum-product pattern (by inspection).The grouping method. The perfect square trinomial pattern. The difference of squares pattern.Knowing the rootsEach method is most likely applicable under certain circumstances. When the polynomial has a leading coefficient of a=1, the sum-product pattern is the fastest and easiest option.
We have the polynomial
[tex]x^2-x-12[/tex]
Here: a=1, b=-1, c=-12
The sum-product method needs us to find two numbers which sum is -1 and product is -12. Those numbers can be found by inspection by combining two divisors of 12, say 1 and 12, 2 and 6, or 3 and 4.
Only one of those pairs can be combined to produce a sum or subtraction equal to -1: Those numbers are -4 and 3. Thus the factorization is:
[tex]\mathbf{x^2-x-12=(x-4)(x+3)}[/tex]
An investor owns a bond. Suppose there is a 20% probability the investor will lose $100 on the bond and an 80% probability the investor will gain $30 on the bond. Find the expected value (expected return) of the bond. Enter the number only. Do not include the $ sign.
======================================================
Work Shown:
A = event of losing $100
P(A) = probability event A occurs = 0.20
V(A) = net gain of event A happening = -100
B = event of gaining $30
P(B) = probability event B occurs = 0.80
V(B) = net gain of event B happening = 30
-----------------
E(X) = expected value
E(X) = P(A)*V(A) + P(B)*V(B)
E(X) = 0.20*(-100) + 0.80*(30)
E(X) = 4
The expected value is $4
This means the investor expects to get an average return of $4.

Jaime is 16 years older than Savannah. Ten years ago, the sum of their ages was 60. How old are they now?
Jaime is ____years old, and Savannah is ____ years old.
Answer:
Jaime is _48_years old, and Savannah is _32_ years old.
Step-by-step explanation:
Jaime is 16 years older than Savannah
Ten years ago, the sum of ages = 60.
(60-16)=22
Ten years ago, Jaime=22+16=38y but now Jaime is 48 (38+10)
Ten years ago, Savannah = 22y but now Savannah is 32y (22+10)

Is this a proportional relationship?

Proportional
Non-proportional
Answer:
ProportionalStep-by-step explanation:
Step one:
given data
We have a question to answer
given that the speed is 6 mph and the time taken is 3 hours
v= 6mph, t= 3, distance =?
distance= speed * time
distance= 6*3= 18miles
From the distance calculated, we can see that there exist a proportional relationship, lets say the time taken is 4 hours, then the distance will be
distance= 6*4= 24 miles.
hence the distance traveled is proportional to the time taken
