Write an equation in point-slope form of the line that passes through the two given points. Use the first point to write the equation (-1, -5) and (3, 2)
Answer:
The equation in point-slope form of the line is:
[tex]y-\left(-5\right)=\frac{7}{4}\left(x-\left(-1\right)\right)[/tex]
Step-by-step explanation:
Given the points
(-1, -5) (3, 2)[tex]\mathrm{Slope\:between\:two\:points}:\quad \mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(-1,\:-5\right),\:\left(x_2,\:y_2\right)=\left(3,\:2\right)[/tex]
[tex]m=\frac{2-\left(-5\right)}{3-\left(-1\right)}[/tex]
[tex]m=\frac{7}{4}[/tex]
As the point-slope form is defined as
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where m is the slope.
substituting the values m=7/4 and the first point (-1, -5)
[tex]y-\left(-5\right)=\frac{7}{4}\left(x-\left(-1\right)\right)[/tex]
Therefore, the equation in point-slope form of the line is:
[tex]y-\left(-5\right)=\frac{7}{4}\left(x-\left(-1\right)\right)[/tex]

Answer: 39
Step-by-step explanation: To find the answer or result of 3 + 3 to the second power + 3 to the third power, you’ll have to find the whole number value of the two integer numbers being 3 to the second power and 3 to the third power. To do this, multiply (3 x 3) and (3 x 3 x 3). You should get 9 and 27. Lastly, you‘ll have to add 3 + 9 + 27, to give you the final answer or result of 39.

The sum of the areas of Square N and Square L is equal to the area of Square K and this can be determined by using the Pythagorean theorem.
Given :
The diagram shows three squares that are joined at vertices to form a right triangle.
The following steps can be used in order to determine which statement is true:
Step 1 - The Pythagorean theorem can be used in order to determine which statement is true.
Step 2 - According to the Pythagorean theorem, the sum of the square of the shorter sides is equal to the square of the longer side.
Step 3 - So, from the above steps, it can be concluded that the sum of the areas of Square N and Square L is equal to the area of Square K.
Therefore, the correct statement is given by option A).

Answer:
We conclude that the estimated volume of a cylinder is 288 in.³
Step-by-step explanation:
Given
r = 3.75 inchesh = 6.21 inchesThe formula to determine the volume of a cyliner is:
[tex]V=\pi r^2h[/tex]
substituting the values r = 3.75 inches, h = 6.21 inches, and π = 3.14 in the formula to calculate the volume of a cylinder.
[tex]V=\pi r^2h[/tex]
[tex]V=\left(3.14\right)\left(3.75\right)^2\times 6.21[/tex]

Transform the equation to isolate x: ax = bx + 1. How is the value of x related to the difference of a and b?
(please help me)
Answer:
x = 1/a-b.
x is the reciprocal of the difference of a and b.
x is 1 over the difference of a and b.
x is the quotient of 1 and the difference of a and b.
Step-by-step explanation:
i did it
The transformation of the given equation ax = bx + 1 for the x will be 1/(a - b).
What is the substitution of an equation?In the by substitution method, one of the equations is calculated for one of the variables, which is then transferred back into the other equation where the chosen variable is a replacement, and the second equation is then calculated for. The first variable is then home safely.
In other words, substitution is a method to find the value of variables x and y by just substituting x and y to another equation.
The substitution method is more good than the elimination method.
Given that the equation
ax = bx + 1
Transfer bx to the left side
ax- bx = 1
Take common x from the left-hand side
x(a - b) = 1
Divide a - b on both sides
x = 1/(a - b) hence it will be the correct transformation.

The radius of a cylindrical water tank is 6.5 ft, and its height is 19 ft. What is the volume of the tank? Use the value 3.14 for pi, and round your answer to the nearest whole number. Be sure to include the correct unit in your answer. (ft, ft^2, or ft^3)
Answer: 2521.91 ft^3
Step-by-step explanation:
Answer:
Step-by-step explanation:
Using the cylinder volume formula, V = (pi)r^2h
Since the radius and the height have already been given, no further calculations are necessary.
V= (pi)(6.5)^2(19)
V=(3.14)(42.25)(19)
2520.635 ft^3
Last week, Lindsay earned $10 per hour plus a $60 bonus for good job performance. She spends StartFraction 1 Over 15 EndFractionof her paycheck on dinner with friends. If she had not earned the bonus, the amount she spent on dinner would have been StartFraction 1 Over 10 EndFraction of her paycheck. Which equation can be used to find h, the number of hours Lindsay worked last week?
Answer:
Let
y--------> cost of the dinner with friends
h--------> the number of hours Lindsay worked last week
we know that
y =\frac{1}{15} *( 10h+60)y=
15
1
∗(10h+60) ------> equation 11
y =\frac{1}{10} *( 10h)y=
10
1
∗(10h) ------> equation 22
equate equation 11 and equation 22
\begin{gathered} \frac{1}{15} *( 10h+60)=\frac{1}{10} *( 10h)\\\\ Multiply\ by\ 150\ both\ sides\\\\ 10*(10h+60)=15*10h\\\\ 100h+600=150h\\\\150h-100h=600\\\\ h=\frac{600}{50} \end{gathered}
15
1
∗(10h+60)=
10
1
∗(10h)
Multiply by 150 both sides
10∗(10h+60)=15∗10h
100h+600=150h
150h−100h=600
h=
50
600
h= 12\ hoursh=12 hours
therefore
the answer is
Lindsay worked 12\ hours12 hours last week
The equation that can be used to find the number of hours is
\frac{1}{15} *( 10h+60)=\frac{1}{10} *( 10h)
15

∗(10h+60)=

Lindsay worked for about 120 hours last week.
What is an equation?An equation is used to show the relationship between two or more variables and numbers.
Let h represent the number of hours Lindsay worked last week, hence:
(1/15)(10h + 600) = (1/10)(10h)
40h + 2400 = 60h
h = 120 hours
Lindsay worked for about 120 hours last week.
