Chin was shown the graph of a line that contained point (1, 7). He wrote f(x) = 4x + 3 to correctly represent the line. Which of these equations could represent the same line?
y – 7 = 3(x – 1)
y – 1 = 3(x – 7)
y – 7 = 4(x – 1)
y – 1 = 4(x – 7)
Answers
The equation that represents the same line containing point (1, 7) is as follows:
y - 7 = 4(x - 1)
Slope intercept form equation:y - y₁ = m(x - x₁)where
m = slope
The graph of the line contains (1, 7) .He represent the line correctly as f(x) = 4x + 3.
The equation that represent the same line is as follows:
Using the model:
y = mx + b
Therefore,
m = 4
Finally , the equation is as follows:
y - 7 = 4(x - 1)learn more on linear equation: https://brainly.com/question/2409163?referrer=searchResults

Step-by-step explanation:
The mirror is set away from the flagpole on the same scale set away from her.
The distance she stand's away from the mirror is 1/4 of the length of the distance between the mirror and the flag pole because she's 1/4 of the flagpole's size.
This means her size x4 is the size for the flag pole. This checks out because 12x4=48

In all triangles, the sum of any two sides must be greater than the third side. To test this, choose the two shortest sides of the triangle and see if they add to be larger than the third side. If this holds true, then the triangle is possible because all other sides you can choose will also hold true.
Trying each of the answer choices, we have:
[tex]\checkmark 10+12> 17,\\\times 5+10 \ngtr 15,\\\times 1+8 \ngtr 10,\\\times 3+7 \ngtr 10[/tex]
Therefore, the answer is 12 cm and 17 cm.

if y varies directly with an x and y=12 when x=-1, find y if x=2
Answers
Answer:
y = -24
Step-by-step explanation:
Direct variation is
y = kx where k is a constant
12 = k*(-1)
12/(-1) =k
-12 = k
The equation is y = -12x
Let x = 2
y = -12(2)
y = -24

En una fábrica, tres de cada veinte jarrones salen con algún defecto. Si se hacen 1000 jarrones, ¿Cuántos saldran defectuosos?
Answers
Answer:
si se hacen 1000 jarrones, 150 saldrán defectuosos.
Step-by-step explanation:
En primer lugar es conveniente determinar el porcentaje de jarrones que salen con algún defecto.
Si 20 corresponde a la cantidad total de jarrones, entonces, se divide 3 sobre 20 para encontrar el porcentaje al que 3 jarrones defectuosos corresponde. La división da como resultado 0,15. Para transformar el valor encontrado en porcentaje, es necesario multiplicar por 100. Entonces, 3 jarrones defectuosos corresponden a 15% de jarrones en total.
Si se hacen 1000 jarrones, es necesario multiplicar por dicho número. Esto es: 15%*1000, obteniendo como resultado 150.
Entonces, si se hacen 1000 jarrones, 150 saldrán defectuosos.

Rita is spending more time at home to study and practice math. Her efforts are finally paying off. On her first assessment she scored 58 points, then she scores 63 and 68 on her next two assessments. If her scores continued to increase at the same rate, on which assessments will she be scoring above 85? Select all that apply.
Answers
Answer:
7th
Step-by-step explanation:
63 - 58 = 5
68-63 = 5
She is adding 5 points each time
a1 = 58
d = 5
a2 = 63
a3 = 68
a4 = 58+5 = 73
a5 = 73+5 = 78
a6 = 78+5 = 83
a7 = 83+5 = 88
This is the first assessment greater then 85, so the 7th assessment

Answers
Answer:
3 3/7 hours
Step-by-step explanation:
The formula is
1/a+1/b = 1/c
where a and b are the times working alone and c is the time working together
1/8 + 1/6 = 1/c
Multiply each side by 24c to clear the fractions
24c(1/8 + 1/6) = 1/c *24c
3c + 4c = 24
7c = 24
Divide by 7
7c/7 = 24/7
c = 3 3/7 hours
Find the measure of each acute angle.
The measure of the top-left angle in the triangle is__º and the measure of the bottom-right angle is__º.
Answers
Answer:
the top angle is 48
the bottom right angle is 42
Step-by-step explanation:
The sum of the angles of a triangle is 180
90 + 8x+7x = 180
Combine like terms
90 +15x = 180
Subtract 90 from each side
15x = 180-90
15x = 90
Divide by 15
15x/15 =90/15
x = 6
8x = 8*6 = 48 so the top angle is 48
7x = 7*6 = 42 so the bottom angle is 42
Solution given:
8x°+7x°+90°=180°[sum of interior angle of a triangle is 180°]
15x=180°-90°
x=90/15
x=6°
8x=8*6=48°
7x=7*6=42°

Answers
Answer:
The answer would be 87^2
Step-by-step explanation:
The solution is, Area of a sector is 138.23 cm².
What is area ?Area is the measure of a region's size on a surface. The area of a plane region or plane area refers to the area of a shape or planar lamina, while surface area refers to the area of an open surface or the boundary of a three-dimensional object.
here, we have,
The formula for the area of a sector is given as:
θ/360 × πr²
θ = 110°
Radius = r = 12 cm
Hence
Area of a sector = 110/360 × π × 12²
= 138.23007676 cm²
Approximately, Area of a sector = 138.23 cm²
Hence, The solution is, Area of a sector is 138.23 cm².
