5x−y=10 3x+y=14 please solve the system of equations and show your work
Answer:
x = 3, y = 5
or (3,5) in coordination point form.
Step-by-step explanation:
We are going to solve the system of equations by combining two equations. To do that, we isolate y-term.
[tex] \large{\begin{cases} 5x - y = 10 \\ 3x + y = 14 \end{cases}}[/tex]
Convert both equations to slope-intercept form.
[tex] \large{ \begin{cases} y = 5x - 10 \\ y = - 3x + 14 \end{cases}}[/tex]
Then combine both equations
[tex] \large{5x - 10 = - 3x + 14} \\ \large{5x + 3x = 10 + 14} \\ \large{8x = 24} \\ \large{x = 3}[/tex]
Substitute x = 3 in one of given equations. I will substitute x = 3 in y = 5x-10
[tex] \large{y = 5x - 10} \\ \large{y = 5(3) - 10} \\ \large{y = 15 - 10} \\ \large{y = 5}[/tex]
Hope this helps!
Chin noticed 1/4 of the watches he bought needed repairs. He also noticed that 1/2 of the good watches had gold bands. If 48 of the good watches had gold bands how many watches did chin buy.
so 48 have gold and 48 is half of the good watches then there is 96 good watches and that's 3/4 of all the watches so the answer would be
128 watches in total
work out the size of angle x
Answer:
∠x = 117°
Step-by-step explanation:
supplement of ∠101° = 79°
all triangle interior angles add up to 180°
180° - 79° - 38° = 63°
the supplementary angle to 63° is 117°

Answer:
m <1 = 64
m<2= 26
Step-by-step explanation:
the angle is 90 degree
therefore, <1 + <2 = 90
(x+51) + (2x) = 90
3x +51 = 90
3x = 39
x = 13
solve using substitution
x^2 -4x+20=0
Answer:
Step-by-step explanation:
x^2 - 4x + 20 = 0
x^2 - 4x = -20
x^2 = 4x - 20
x = 2x - 4.47
-3x = -4.47
x = roughly 1.5

4. An equilateral triangle has a perimeter of 60 cm. Find the exact
altitude of the triangle.
Step-by-step explanation:
GIVEN:-The Perimeter of Equilateral triangle = 60cm
UNDERSTANDING THE CONCEPT:-According to the question,
To find the height of the triangle,
Perimeter of Equilateral triangle = Area of Equilateral triangle.
FORMULA USED:-[tex]60 = \frac{ \sqrt{3} }{4} a {}^{2} \\ [/tex]
REQUIRED ANSWER:-[tex]60 \times 4 = \sqrt{3a {}^{2} } [/tex]
[tex]a {}^{2} = 240 \sqrt{3} \\ [/tex]
[tex]a = 120 \sqrt{3} cm[/tex]
SO, The Exact height of the triangle is 120√3cm.Use the quadratic formula to find the solution to the quadratic equation given below. x^2-3x+9/4 =0
Answer:
[tex] x = \dfrac{3}{2} [/tex]
Step-by-step explanation:
x^2-3x+9/4 =0
Multiply both sides by 4 to get rid of the fraction.
4x^2 - 12x + 9 = 0
[tex] x = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a} [/tex]
[tex] x = \dfrac{-(-12) \pm \sqrt{(-12)^2 - 4(4)(9)}}{2(4)} [/tex]
[tex] x = \dfrac{12 \pm \sqrt{144 - 144}}{8} [/tex]
[tex] x = \dfrac{12}{8} [/tex]
[tex] x = \dfrac{3}{2} [/tex]

A cylinder and a cone have the same height and radius. The height of each is 5 centimeters, and the radius is 2 centimeters. Calculate the volume of the cylinder and the cone (rounded to the nearest tenth). Use 3.14 as an approximation for n. PLS HELP 15 POINTS
Answer:
Step-by-step explanation:
volume of cylinder = πr²h = 3.14·2²·5 = 62.8 cm³
volume of cone = ⅓πr²h = ⅓·62.8 ≅ 20.9 cm³
The volume of the cone is 10.5 cm³. The volume of the cylinder is 31.4 cm³
What is the volume of the cylinder and the cone?
Volume of a cone = 1/3(nr^2h)
n = 22/7
r = radius
h = height
1/3 x 3.14 x 5 x 2 = 10.5 cm³
Volume of the cylinder = nr^2h
3.14 x 5 x 2 = 31.4 cm

The difference of b and 4 is at most 15.
Answer:
b - 4 ≤ 15
b ≤ 19
Step-by-step explanation:
The statement "at most" typically means no more than, so the inequality sign would have to be "less than or equal to"
To solve for be all you would do is add 4 to both sides to get b by itself.
b - 4 ≤ 15
b - 4 + 4 ≤ 15 + 4
(-4 + 4 cancels itself out)
(15 + 4 = 19)
b ≤ 19

What are the measures of ∠1 and ∠2? PLEASE ANSWER
m∠1 = 58.2°, m∠2 = 75.5°
m∠1 = 67.4°, m∠2 = 104.5°
m∠1 = 75.5°, m∠2 = 67.4°
m∠1 = 104.5°, m∠2 = 58.2°
9514 1404 393
Answer:
(b) m∠1 = 67.4°, m∠2 = 104.5°
Step-by-step explanation:
It is easiest to find angle 2 first, then make your answer selection based on that.
The exterior angle 121.8° is the sum of the remote interior angles 17.3° and angle 2. Then ...
angle 2 = 121.8° -17.3° = 104.5° . . . . . . . matches the second choice
__
Angle 2 is an exterior angle of the top triangle. It, too, is the sum of the remote interior angles:
104.5° = angle 1 + 37.1°
angle 1 = 104.5° -37.1° = 67.4°
Answer:
C!
Step-by-step explanation:
m∠1 = 75.5°, m∠2 = 67.4°
