Answer:
x = - 1, x = 7
Step-by-step explanation:
Given
x² - 6x - 7 = 0
Consider the factors of the constant term (- 7) which sum to give the coefficient of the x- term (- 6)
The factors are - 7 and + 1, since
- 7 × 1 = - 7 and - 7 + 1 = - 6, thus
(x - 7)(x + 1) = 0
Equate each factor to zero and solve for x
x - 7 = 0 ⇒ x = 7
x + 1 = 0 ⇒ x = - 1
1. given w(x)=4x
a. graph r(x)=4 x w(x). then complete the table of corresponding points on r (x).
Answer:
Step-by-step explanation:
a). When graph w(x) is transformed to r(x) = 4 × w(x), graph of w(x) is vertically stretched by a scale factor of 4.
Table for the corresponding points will be,
x w(x) r(x)
0 0 0×4 = 0
15 60 60×4 = 240
30 120 120×4 = 480
45 180 180×4 = 720
b). As discussed in part (a), graph of w(x) will be vertically stretched by a scale factor of 4 to produce the graph of r(x).
c). Since, w(x) = 4x
and r(x) = 4[w(x)]
r(x) = 4(4x) = 16x
r(x) = 16x

what is the solution to the system of equations? 3x-2y=19 y=x-7
A) (6,-1)
B) (33,26)
C) (1,-6)
D) (5,-2)
Step-by-step explanation:
3x - 2y = 19 ...1
Replace y = x-7 in ...1
3x - 2(x-7) = 19
3x - 2x + 14 = 19
x = 19 - 14
= 5
Replace x = 5 in y = x - 7
y = 5 - 7
= -2

Answer:
x=-7
Step-by-step explanation:
Let's solve your equation step-by-step.
−2(3x+9)=24
Step 1: Simplify both sides of the equation.
−2(3x+9)=24
(−2)(3x)+(−2)(9)=24(Distribute)
−6x+−18=24
−6x−18=24
Step 2: Add 18 to both sides.
−6x−18+18=24+18
−6x=42
Step 3: Divide both sides by -6.
−6x /−6
= 42 /−6
x=−7

m∠DOB = m∠DOE + m∠BOE
m∠DBO = 90 + x
m∠DOB = m∠AOC {Vertically opposite angles}
110 = 90 +x
x = 110 - 90 = 20
Answer:
x=20
Step-by-step explanation:
m∠DOB = m∠DOE + m∠BOE . parts whole postulate
m∠DBO = 90 + x subs
m∠DOB = m∠AOC verticle angles
110 = 90 +x . subs
x = 110 - 90 = 20 alg

A banker earns a $75,000 annual salary, a 2.35% commission on any approved loans for the bank’s business customers, and a fee of $3.75 for each application processed. If the banker has a total of $2.8 million in approved business loans and processes 2,750 applications this year, what are the banker’s earnings rounded to the nearest dollar?
Answer:
Amount earned = $151,113
Step-by-step explanation:
Here, we are interested in calculating the banker’s earnings rounded to the nearest dollar;
We proceed as follows; we have the following;
1. Annual salary of $75,000
2. 2.35% on approved loans.
Approved loans = 2.8 million
Commission = 2.35/100 * 2.8 million = $65,800
3. $3.75 for each processed loan application
Total = 2750
Amount = 3.75 * 2750 = $10,312.50
Total amount earned is thus;
$75,000 + $65,800 + $10,312.50 = 151,112.5 = 151,113 to the nearest dollar
Answer:

[tex]2a { }^{2} b {}^{2} - 7ab - 30[/tex]
Answer:
(ab - 6)(2ab + 5)
Step-by-step explanation:
Assuming you require the expression factorised.
2a²b² - 7ab - 30
Consider the factors of the product of the coefficient of the a²b² term and the constant term which sum to give the coefficient of the ab- term
product = 2 × - 30 = - 60 and sum = - 7
The factors are - 12 and + 5
Use these factors to split the ab- term
= 2a²b² - 12ab + 5ab - 30 ( factor the first/second and third/fourth terms )
= 2ab(ab - 6) + 5(ab - 6) ← factor out (ab - 6) from each term
= (ab - 6)(2ab + 5) ← in factored form
4. Using the given information, which lines, if any, can you conclude are parallel? Justify your conclusion with a theorem or postulate. Angle 1 is supplementary to angle 4. 9/11 v 1/5 2/6 10/12 b A 3/7 4 8 1 O || m by Converse of the Corresponding Angles postulate Oa || b by Converse of the Corresponding Angles Postulate Ollm by Converse of the Same-Side Exterior Angles Theorem Oa || b by Converse of the Same-Side Exterior Angles Theorem
Answer:
Option (4)
Step-by-step explanation:
It has been given in the question that angle 1 is supplementary to angle 4.
m∠1 + m∠4 = 180°
∠2 and ∠3 are the interior consecutive angles.
Since, same side of the theorem says "Exterior angles formed on the same side of the parallel lines and the transversal line are supplementary".
Therefore, by converse of the same side Exterior angles theorem 'a' and 'b' will be parallel.
Option (4) will be the answer.

In January, a city’s snowfall was 5/8 foot below the historical average. In February, the snowfall was 3/4 foot above the historical average. Was the city’s snowfall in the two-month period above or below the historical average? By how much?
Answer:
The city's snowfall in the two-month period was above the historical average by 1/8 feet
Step-by-step explanation:
Fractions
The question provides the following information: In January, a city’s snowfall was 5/8 feet below the historical average. Let's assume the snowfall level to be positive if it's above the historical average and negative otherwise.
The data from January gives us a snowfall of -5/8 feet because it was below the average.
We also know in February, the snowfall was 3/4 foot above the historical average. Following our predefined convention, the data from February gives us a snowfall of +3/4 feet.
To know if the city's snowfall during the two-month period was above or below the historical average, we just need to add them, signs included.
If the result is negative, the two-month period showed a snowfall below the historical average.
Let's find the sum of
[tex]\displaystyle -\frac{5}{8}+\frac{3}{4}[/tex]
The LCM of 4 and 8 is 8, thus:
[tex]\displaystyle -\frac{5}{8}+\frac{3}{4}=\frac{-5+2*3}{8}=\frac{1}{8}[/tex]
Since this quantity is positive, we can say the city's snowfall in the two-month period was above the historical average by 1/8 feet.
