What is the solution to the system of eqautions represented by these two lines?
Answer:
Step-by-step explanation:
A or C
Answer:
The solution to the system of equations represented by these two lines is:
(2, 0)Hence, option C i.e. (2, 0) is correct.
Step-by-step explanation:
Please note that the point of intersection between two lines is the solution of the system of equations.
From the graph, it is clear that two lines intersect at x = 2 and y = 0.
In other words, the point of intersection of the two lines is:
(x, y) = (2, 0)
Therefore, the solution to the system of equations represented by these two lines is:
(2, 0)Hence, option C i.e. (2, 0) is correct.

In △XYZ, angle X is the smallest angle, angle Y is 40 degrees more than angle X, and angle Z is 2 times the measure of angle X. What is the measure of angle X?
Answer:
x=35° y= 75° z = 70°
Step-by-step explanation:
Y = x+40 (known)
z = 2x (known)
x + y + z = 180 (triangle property)
x + (x+40) + 2x = 180 (substitution)
4x + 40 = 180
4x = 140
x = 35
y = x + 40 = 75
z = 2x = 70

What is a reasonable estimate for the solution? O (1,-3/4) O (-3/4,1) O (-1,3/4) O (3/4,-1)
Answer:
See Explanation
Step-by-step explanation:
Your question is incomplete, as the equations or graph or table(s) were not given.
However, I'll give a general way of solving this.
Take for instance, the equations are:
[tex]y = \frac{4}{3}x - 1[/tex]
[tex]y = \frac{2}{3}x - \frac{1}{2}[/tex]
To do this, we start by equating both equations.
[tex]y = y[/tex]
i.e.
[tex]\frac{4}{3}x - 1= \frac{2}{3}x - \frac{1}{2}[/tex]
Collect Like Terms
[tex]\frac{4}{3}x - \frac{2}{3}x= 1 - \frac{1}{2}[/tex]
Take LCM
[tex]\frac{4x- 2x}{3}= \frac{2 - 1}{2}[/tex]
[tex]\frac{2x}{3}= \frac{1}{2}[/tex]
Cross Multiply
[tex]2x * 2 = 3 * 1[/tex]
[tex]4x = 3[/tex]
Make x the subject
[tex]x = \frac{3}{4}[/tex]
Substitute 3/4 for x in [tex]y = \frac{4}{3}x - 1[/tex]
[tex]y = \frac{4}{3} * \frac{3}{4} - 1[/tex]
[tex]y = 1 - 1[/tex]
[tex]y = 0[/tex]
Hence:
[tex](x,y) = (\frac{3}{4},0)[/tex]

The answer is ( D )

Given a quadrilateral DEFG. If angle ED is supplementary to ____________then DEFG is a parallelogram .
A. angle EFG and angle DEF B. angle DGF and angle EFC C. angle DEF and angle DGF
Answer:
The correct option is A.
Step-by-step explanation:
It is given that DEFG is a parallelogram.
Draw the diagonals DF and EG. Place point H where DF and EG intersect.
In triangle HGD and HEF
,
∠HGD ≅ ∠HEF (Alternate Interior angle)
∠HDG ≅ ∠HFE (Alternate Interior angle)
By the definition of a parallelogram, the opposite sides of a parallelogram are congruent.
DG ≅ EF (Opposite sides of parallelogram)
According to ASA postulate :
two triangles are congruent if any two angles and their included side are equal in both triangles.
So, by using ASA criterion for congruence we get,
ΔDGH ≅ ΔFEH
Since corresponding sides of congruent triangles are congruent, therefore
GH ≅ EH (CPCTC)
DH ≅ FH (CPCTC)
Write y = x2 – 18x + 52 in vertex form.
a
y = (x – 9)2 + 113
b
y = (x – 9)2 – 29
c
y = (x + 9)2 – 29
d
y = (x – 9)2 + 52
Answer:
b is the correct answer
y=a(x+n)^2+k
vertex: -b/2a 18/2=9
y=1(x-9)^2
k=9^2-18(9)+52= 81-162+52=-29
y=(x-9)^2-29
Del sells his goods for £54.60 making a 9% loss how much did he pay for the good when he bought them?
Answer:
£54.65
Step-by-step explanation:
Del sells his goods for £54.60 making a 9% loss how much did he pay for the good when he bought them?
We are to find the cost price.
Loss = Cost price - Selling price
Percentage loss =
(Cost price - Selling price/Cost price) × 100
Percentage loss = 9% = 0.09
Selling price = £54.60
Cost price = x
Hence:
0.09 = x - £54.60/x × 100
0.09 = 100(x - £54.60)/x
Cross Multiply
0.09x = 100(x - £54.60)
0.09x = 100x - 5460
100x - 0.09x = 5450
99.91x = 54.50
x = 5460 / 99.91
x = 54.649184266
Approximately, x = £54.65
Therefore, the cost price = £54.65

What are the values of x and y?
Answer
the one in the bottom right
Step-by-step explanation:
Answer:
option 2
Step-by-step explanation:
Using the cosine and sine ratios in the right triangle and the exact values
cos30° = [tex]\frac{\sqrt{3} }{2}[/tex] , sin30° = [tex]\frac{1}{2}[/tex]
cos30° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{x}{20\sqrt{3} }[/tex] = [tex]\frac{\sqrt{3} }{2}[/tex] ( cross- multiply )
2x = 60 ( divide both sides by 2 )
x = 30
--------------------------------------------------
sin30° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{y}{20\sqrt{3} }[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )
2y = 20[tex]\sqrt{3}[/tex] ( divide both sides by 2 )
y = 10[tex]\sqrt{3}[/tex]

Consider angle θ in Quadrant lI, where cosθ = - 12/13. What is the value of sinθ?
Answer:
The value of sin Ф is [tex]\frac{5}{13}[/tex]
Step-by-step explanation:
In quadrant II, the value of
sin Ф is positivecos Ф is negativetan Ф is negativeLet us solve the question
∵ sin²Ф + cos²Ф = 1
∵ cos Ф = [tex]\frac{-12}{13}[/tex]
→ Substitute it in the identity above
∴ sin²Ф + ([tex]\frac{-12}{13}[/tex])² = 1
∴ sin²Ф + [tex]\frac{144}{169}[/tex] = 1
→ Subtract [tex]\frac{144}{169}[/tex] from both sides
∵ sin²Ф + [tex]\frac{144}{169}[/tex] - [tex]\frac{144}{169}[/tex] = 1 - [tex]\frac{144}{169}[/tex]
∴ sin²Ф = [tex]\frac{25}{169}[/tex]
→ Take the square root of both sides
∵ √(sin²Ф)= ± [tex]\sqrt{\frac{25}{169}}[/tex]
∴ sin Ф = ± [tex]\frac{5}{13}[/tex]
∵ Ф is in quadrant II
∴ sin Ф is a positive value
∴ sin Ф = [tex]\frac{5}{13}[/tex]
∴ The value of sin Ф is [tex]\frac{5}{13}[/tex]
Si una galleta de chocolate aporta un aproximado de 150 kcal y un viaje en bicicleta se quema por media hora se que mas 340 kcal cuanto tiempo necesita una persona en viaje para quemar 5 galletas
Answer:
Una persona necesitará 2 horas y 30 minutos de viaje en bicicleta para quemar el contenido kilocalórico de cinco galletas.
Step-by-step explanation:
De acuerdo con este problema, la cantidad de calorías que se quema es directamente proporcional al tiempo de viaje en bicicleta. Si sabemos que una galleta aporta 150 kilocalorías, entonces 5 galletas equivalen a 750 kilocalorías.
Por regla de tres simple calculamos el tiempo requerido para quemar 750 kilocalorías:
[tex]x = 30\,min \times \frac{750\,kcal}{150\,kcal}[/tex]
[tex]x = 150\,min[/tex]
Es decir, una persona necesitará 2 horas y 30 minutos de viaje en bicicleta para quemar el contenido kilocalórico de cinco galletas.
what is the solution of the proportion?
x-6/4 = 2/4
a 9/2
b 5/2
c 21/2
d 18
Answer:
Solution of the proportion: [tex]\frac{x-6}{4}=\frac{2}{4}[/tex] is x=8.
Step-by-step explanation:
We need to find solution of the proportion: [tex]\frac{x-6}{4}=\frac{2}{4}[/tex]
For solving the equation, first we will multiply both sides by 4
[tex]\frac{x-6}{4}=\frac{2}{4}[/tex]
[tex]4\times \frac{x-6}{4}=4\times \frac{2}{4}[/tex]
[tex]x-6=4(\frac{2}{4})[/tex]
Simplifying
[tex]x-6=2[/tex]
Adding 6 on both sides
[tex]x-6+6=2+6x=8[/tex]
So, solution of the proportion: [tex]\frac{x-6}{4}=\frac{2}{4}[/tex] is x=8.
Note: Kindly recheck your options as correct answer is x =8.
