Answer:
5²x²- 49
Factoring: 25x2-49
A difference of two perfect squares, A²- B²can be factored into (A+B) • (A-B)
Proof : (A+B) • (A-B) =
A²- AB + BA - B²=
A² - AB + AB - B² =
A²- B²
25 is the square of 5
49 is the square of 7
x²is the square of x¹

In the table for the Thompsons, how much of their net worth is readily available for use?
A)$1,520
B)$10.770
C)$12.345
D)$14.320
lol the other guy was so confidently wrong it's actually A) 1,520
Thompson's net worth is US$ 37,742
What is addition?Addition is a way of combining things and counting them together as one large group. ... Addition in math is a process of combining two or more numbers.
here, we have,
Total Assets of the Thompson Family:
Total Assets = 1,520 + 9,250 + 112,340 + 12,800
Total Assets = 135,910
Total Liabilities of the Thompson Family:
Total Liabilities = 5,238 + 580 + 78,570 + 13,780
Total Liabilities = 98,168
Net worth of the Thompson Family
Net worth = Total Assets - Total Liabilities
Net worth = 135,910 - 98,168
Net worth = 37,742
Hence, Thompson's net worth is US$ 37,742

Step-by-step explanation:
plz give me brainlyest i need it
Answer:
Option 1
Step-by-step explanation:
[tex]3 {x}^{2} - 18x + 5 = 47[/tex]
[tex] = > 3 {x}^{2} - 18x + 5 - 47 = 0[/tex]
[tex] = > 3 {x}^{2} - 18x - 42 = 0[/tex]
[tex] = > 3( {x}^{2} - 6x - 14) = 0[/tex]
[tex] = > {x}^{2} - 6x - 14 = 0[/tex]
We know that
[tex]x = \frac{ - b + \sqrt{d} }{2a} \: or \: \frac{ - b - \sqrt{d} }{2a} [/tex]
Where D = Discriminant of the eqn.
Discriminant of the above eqn.=
[tex] {b}^{2} - 4ac = {( - 6)}^{2} - 4 \times ( - 14) \times 1 = 92[/tex]
So,
[tex]x = \frac{ - ( - 6) + \sqrt{92} }{2 \times 1} \: or \: \frac{ - ( - 6) - \sqrt{92} }{2 \times 1} [/tex]
[tex] = > x = \frac{6 + 2 \sqrt{23} }{2} \: or \: \frac{6 - 2 \sqrt{23} }{2} [/tex]
[tex] = > x = (3 + \sqrt{23} ) \: or \: (3 - \sqrt{23} )[/tex]

how is the standard form, intercept form, and vertex useful when writing a parabola. (how is each form useful )
Answer:
The intercept form gives the x-intercepts, y-intercepts, and concavity of the parabola. Vertex form is most useful when graphing, since finding the vertex is much easier. Finally, standard form helps you find concavity and each a, b, and c terms tell different things about the postition of the parabola. Generally, this form is factored into one of the other forms. Hope this helped!

Step-by-step explanation:
Machine A can label 11 bottles in 1 minute. Machine B can label 14 bottles in 1 minute. How many bottles can both machines label in 15 minutes?
Answer:
Machine 1: 165
Machine 2: 210
Step-by-step explanation:
Machine 1: 11 bottle per minute
11 * 15 = 165 labeled bottles per minute
Machine 2: 14 bottles per minute
14*15 = 210 labeled bottles per minute
different question: You and your friend skate at the same rate. You complete 6 laps in 5 minutes. How long does your friend take to complete 18 laps?
Answer: 15 minutes
Step-by-step explanation:
Since we skate at same rate and I complete 6 laps in 5 minutes. The number of minutes that my friend will take to complete 18 laps would be calculated as:
= 18 ÷ 6/5
= 18 × 5/6
= 3 × 5
= 15 minutes
(1) Today, the temperature in New York is -1 degree and is expected to rise 3 degrees per day. It's 6
degrees in Alaska and expected to fall 1 degree every 2 days.
Answer:
New York: m=3, b=-1, y=3x-1
Alaska: m=-1/2, b=6, y=-1/2x+6
2 days; 5 degrees
Step-by-step explanation:
In each case, m is the rate of change, the number of degrees per day that the temperature is changing. 1 degree per 2 days is 1/2 degree per day.
In each case, b is the given initial temperature.
The equation is y = mx + b, for the values of m and b that you fill in.
New York
m = 3, b = -1, equation: y = 3x -1
Alaska
m = -1/2, b = 6, equation: y = -1/2x +6
__
The graphs can be plotted by plotting the initial point on the y-axis, then finding another point based on the slope.
For New York, another point will be 1 unit right and 3 units up, at (1, 2).
For Alaska, another point will be 2 units right a 1 unit down, at (2, 5).
The lines intersect at the point (2, 5) corresponding to 2 days, 5 degrees.

A unit rate is a ratio in fraction form that has a _______of 1
2. Given HS has endpoints H(5, -9) and S(-10, 11), find the coordinates of P so that P partitions HS in a ratio 2:3.
Point P?
Answer:
The coordinates of point P are (-1, -1)
Step-by-step explanation:
The coordinates of the partition point (x, y) of a line segment whose endpoints are (x1, y1) and (x2, y2) at ratio m: n are
x = [tex]\frac{mx2+nx1}{m+n}[/tex]y = [tex]\frac{my2+ny1}{m+n}[/tex]∵ P partitions segment HS in a ratio 2: 3
∴ P = (x, y)
∴ m = 2 and n = 3
∵ H = (5, -9) and S = (-10, 11)
∴ x1 = 5 and x2 = -10
∴ y1 = -9 and y2 = 11
→ Substitute them in the rule above to find x and y
∵ x = [tex]\frac{2(-10)+3(5)}{2+3}[/tex] = [tex]\frac{-20+15}{5}[/tex] = [tex]\frac{-5}{5}[/tex]
∴ x = -1
∵ y = [tex]\frac{2(11)+3(-9)}{2+3}[/tex] = [tex]\frac{22-27}{5}[/tex] = [tex]\frac{-5}{5}[/tex]
∴ y = -1
∴ The coordinates of point P are (-1, -1).

Step-by-step explanation:
Diego is attending UTEP and has completed some courses worth 3 credits and some course worth 4 credits. he has earned a total of 59 credits after completing 18 courses. How many courses worth 4 credits has Diego completed
Answer:
3 credit course = 13
4 credit course = 5
Step-by-step explanation:
Given that :
Total credits = 59
Total courses = 18
Let :
Number of 3 credit course = x ; number of 4 credit course = y
x + y = 18 - - (1)
3x + 4y = 59 - - - (2)
x = 18 - y
3(18 - y) + 4y = 59
54 - 3y + 4y = 59
54 + y = 59
y = 59 - 54
y = 5
x = 18 - 5
x = 13
3 credit course = 13
4 credit course = 5
