what is the equation in point slope form of a line that passes through the points (-4,-1)and5,7)
Answer:
[tex]\frac{8}{9}[/tex]
Step-by-step explanation:
using the image attached as reference
(-4,-1) - the -4 becomes x1, and the -1 becomes y1
(5,7) - the 5 becomes x 2 and the 7 becomes y2
plug this information into the equation
7-(-1)
m=----------
5-(-4)
solve
8
m=----------
9
so your slope would become 8/9

The center of a circle and a point on the circle are given. Write the equation of the circle in standard form.
center: (2,-5), point on the circle: (-4,-5)
Answer:
25= (x-2)² + (y+4)²
Hope this helps!!!
Answer:
[tex](x-2)^2+(y+5)^2=36[/tex]
Step-by-step explanation:
The standard form of a circle is given by the equation:
[tex](x-h)^2+(y-k)^2=r^2[/tex]
Where (h, k) is the center and r is the radius.
We know that the center is (2, -5). So, we can substitute 2 for h and -5 for k. This yields:
[tex](x-(2))^2+(y-(-5))^2=r^2[/tex]
Simplify:
[tex](x-2)^2+(y+5)^2=r^2[/tex]
Now, we need to determine r. We know that a point on the circle is (-4, -5). Thus, we can determine r by substituting -4 for x and -5 for y. This yields:
[tex](-4-2)^2+(-5+5)^2=r^2[/tex]
Evaluate:
[tex](-6)^2+(0)^2=r^2[/tex]
Evaluate:
[tex]36=r^2[/tex]
Hence, the radius squared is 36.
We do not actually need to solve for r, as we will square it anyways.
We will substitute 36 for r squared. Hence, our equation is:
[tex](x-2)^2+(y+5)^2=36[/tex]
The radius will thus be 6 units.

a. 18°
b. 72°
c. 90°
d. 108°
Answer:
A. 18°
Step-by-step explanation:
Using the cofunction identity
sin x = cos(90 - x)
Hence
sin72° = cos(90 - 72)° = cos18° ⇒ ∠Y = 18°
Answer:
The answer is 18.

Answer: 56
Step-by-step explanation:
Answer:
112% of 50 is 56
Step-by-step explanation:
100% of 50 is 50.
We have to find 12% of 50, and then add it to 50 to get 112% of 50.
12% of 50 is the same as .12 x 50 which is 6.

Nora is 4 years older than Hina . If the sum of their ages is at most 45 years ,find the maximum possible age of Hina. *
b) 25 years
a) 20 years
c) 15 years
choose the correct answer
Answer:
a) 20 years
Step-by-step explanation:
Hina: x
Nora: x + 4
x + x + 4 ≤ 45
2x + 4 ≤ 45
2x ≤ 41
x ≤ 20.5
20 years old and 15 years old would be ≤ 20.5 but the question asked for maximum possible age so 20 years old it is.
Which of the following is a factor of 7x2 - 12x - 4? (6 points)
O 7x - 2
O x + 2
Ox-4
O None of the above
Answer:
We conclude that 'None of the above' is the correct answer.
Step-by-step explanation:
Given the expression
[tex]7x^2\:-\:12x\:-\:4[/tex]
Breaking the expression into groups
[tex]7x^2\:-\:12x\:-\:4=\left(7x^2+2x\right)+\left(-14x-4\right)[/tex]
Factor out [tex]x[/tex] from [tex]7x^2\:+\:2x[/tex]
[tex]=x\left(7x+2\right)[/tex]
Factor out -2 from [tex]\left(-14x-4\right)[/tex]
[tex]=-2\left(7x+2\right)[/tex]
so the expression becomes
[tex]7x^2\:-\:12x\:-\:4=\left(7x^2+2x\right)+\left(-14x-4\right)[/tex]
[tex]=x\left(7x+2\right)-2\left(7x+2\right)[/tex]
Factor out the common term [tex]7x+2[/tex]
[tex]=\left(7x+2\right)\left(x-2\right)[/tex]
Therefore, from the given options, we conclude that 'None of the above' is the correct answer.

71 2/3 as a fraction
Answer:
215/3
Step-by-step explanation:
71 multiplied by 3 (denominator) + 2 (remainder) divided by 3
The improper fraction for the given mixed fraction is 215/2.
The given fraction is [tex]71\frac{2}{3}[/tex].
These are just improper fractions written as a sum of whole number and a proper fraction. (improper fraction has the upper value(also called numerator) bigger or equal to denominator(the bottom value) and proper fraction has numerator value is less than that of the denominator)
They are written and can be converted to fraction as: [tex]a\frac{b}{c} = \frac{(a\times c)+b}{c}[/tex]
Now, [tex]71\frac{2}{3}=\frac{71\times3+2}{3}[/tex]
= (213+2)/3
= 215/3
Therefore, the improper fraction for the given mixed fraction is 215/2.
