Answer:
Step-by-step explanation:
x2 - 49
Both are squares so
Square root (x2) - Square root (49)
= x - 7
The other two answers are x - 3 and x - 4
Answer:
Use the formula (x-a)(x+a)=x^2 - a^2
so what is the square root of 49, 9, and 16? By finding the square root you get a, and you can just plug it into the formula. For example the first one, 7 is the square root of 49. So, (x-7)(x+7)

Please help me with this .
Answer:
x=4
Step-by-step explanation:
It's a parallel line so the equation is
100+19x+4=180
19x=180-100-4
19x=76
x=76/19
x=4
Answer: x = 4
Step-by-step explanation: The 2 angles are same-side interior angles, which are supplementary, and supplementary angles add up to 180, so we know that 19x + 4 = 80.
- 4. -4
19x = 76
/19. /19

Solve the following quadratic by completing the square. (Hint: It won't factor) x2-10x+5=0
[tex]5+2\sqrt{5} , 5-2\sqrt{5}[/tex] Answer: 5±2[tex]\sqrt{5}[/tex]
Step-by-step explanation:
x2 -10x=5=0
x2-10x+25=-5+25
(x-5)(x-5)=20
[tex](x-5)^{2} =\sqrt{20}[/tex]
[tex]\sqrt{x-5}=\sqrt{20}[/tex]
x-5=±[tex]\sqrt{20[/tex]
x=5±[tex]\sqrt{5*4[/tex]
x=5±2[tex]\sqrt{5}[/tex]

Mr Mason asks 240 year 11 students what they want to do next year. 15% of the students want to go to college. ¾ of the students want to stay at school. The rest of the students do not know. Work out the number of students who do not know.
Answer:
Number of students who do not know = 24
Step-by-step explanation:
Year II students = 240
15% of the students want to go to college.
Number of year II students who wants to go to college = 15% of 240
= 15/100 × 240
= 0.15 × 240
= 36
¾ of the students want to stay at school.
Number of students who wants to stay at the school = 3/4 × 240
= (3 × 240) / 4
= 720 / 4
= 180
Number of students who do not know = Total year II students - Number of year II students who wants to go to college - Number of students who wants to stay at the school
= 240 - 36 - 180
= 24
Number of students who do not know = 24
What's 4/5 as a percentage?
Answer:
80%
Step-by-step explanation:
% is out of 100 so make the denominator of 4/5 to be 100:
4/5 times 20/20 = 80/100 = 80%
Answer:
80%
Step-by-step explanation:
4 divided by 5 equal .8
.8 x 100 equals 80
It's multiplied by 100 because usually percentages are out of 100.
OR
You can move the decimal in .8 to 2 space to the right

Answer:
25.) Slope of AB = 5
Slope of CD = -1/5
Perpendicular
26.) Slope of EF = -3/5
Slope of GH = -3/5
Parallel
Step-by-step explanation:
Use this formula to find slope. [tex]\frac{y2 - y1}{x2 - x1}[/tex]
Parallel lines have the same slope
Perpendicular lines have the opposite reciprocal and sign
25.)
Plug in AB slope is 5
2 - 7/ 3 - 4 = -5/-1 = 5
Plug in for CD slope is -1/5
3 - 4/ 2 - -3 = -1/5 = -1/5
The lines AB and CD are perpendicular because they have opposite reciprocals and opposite signs.
26.)
Plug in EF slope is -3/5
1 - 4/ 3 - -2 = -3/5 = -3/5
Plug in GH slope is -3/5
-5 - -2/ 4 - -1 = -3/5 = -3/5
The lines EF and GH are parallel lines because they have the same slopes.
Hope this helps ya!

Find that x and y intercept 4x-5y=40
Answer:
x intercept: 10, y intercept: -8
Step-by-step explanation:
make into y = mx + b
4x = 5y + 40
4x - 40 = 5y
y = 4/5x - 8
plug in 0 for x, to find y intercept
y = -8
plug in 0 for y, to find x intercept
0 = 4/5x - 8, x = 10

Two companies rent moving trucks. Pack and Go charges a $39.95 flat fee, and $0.45 for every mile driven. U-Drive charges a $59.95 flat fee, and $0.35 for every mile driven. At how many miles is the cost of the truck rentals the same?
Answer:
The indifference point is 200 miles
Step-by-step explanation:
First, we need to establish the total cost formula for each company:
Pack and Go:
Total cost= 39.95 + 0.45x
x= miles driven
U-Drive:
Total cost= 59.95 + 0.35x
x= miles driven
Now, we equal both formulas and isolate x:
39.95 + 0.45x = 59.95 + 0.35x
0.1x = 20
x= 200 miles
The indifference point is 200 miles
Answer:
A is answer 1/ 39.95 + .45x = 59.95 + .35x
B is answer 3/ miles driven
C is 3 /200
