Answer:
2. y - (-5) = -3 (x - 5)
3. y = -5/2
Step-by-step explanation:
Point intercept form: y - y₁ = m (x - x₁)
Where y and x are just kept as y and x, y₁ and x₁ are the parts of a coordinate, and m = slope.
2. The points are (5, -5) and the slope is -3. Plug this into y - y₁ = m (x - x₁) to get
y - (-5) = -3 (x - 5)
3. As stated, parallel lines have the same slope, so the slope of the line would be -5/2. The origin is (0, 0), so plug these two numbers in.
y - y₁ = m (x - x₁)
y - 0 = -5/2 (x - 0)
y = -5/2

Write an inequality for each graph. (photos down below)
p(x)+p(x+3)=10x-7 find p(3)
Answer:
Simplify each term.
Px+px+3p=10x−7
Move all terms not containing P to the right side of the equation.
Px=10x−7−px−3p
Divide each term by x and simplify.
P=10−7/x−p−3p/x

Determine the value of x in each figure.
PLEASE HELPPPP
Answer:
x=3
Step-by-step explanation:
Hello There!
The shown angles have a sum of 90 degrees
This is noticeable because there is a square at the vertex which indicates that its a right angle
A right angle has a measure of 90 degrees
That being said we can create an equation to solve for x
90 = 66 + 8x having made an equation we now solve for x
step 1 subtract 66 from each side
90 - 66 = 24
66 - 66 cancels out
now we have
24 = 8x
step 2 divide each side by 8
8x/8=x
24/8=3
we're left with x = 3
Answer:
x=3
Step-by-step explanation:
8x+66=90 complement
8x=90-66
x=24/8=3
A 12.5-foot ladder is leaning against the side of a house. If the ladder is resting 12 feet off the ground, how far is the ladder from the house?
A. 2 feet
B. 3.5 feet
C. 6.25 feet
D. 7 feet
Answer:
B. 3.5 feet
Step-by-step explanation:
The part leaning against the wall is the hypotenuse while the height of the ladder off the ground is the opposite and the distance of the ladder from the house is the adjacent side.
Given the following data;
Hypotenuse = 12.5 ft
Opposite = 12 ft
To find the adjacent side, we would use the Pythagorean theorem;
Hypotenuse² = opposite² + adjacent²
Substituting into the formula, we have;
12.5² = 12² + adjacent²
156.25 = 144 + adjacent²
Adjacent² = 156.25 - 144
Adjacent² = 12.25
Taking the square root of both sides, we have;
Adjacent = 3.5 feet.
Therefore, the distance of the ladder from the house is 3.5 feet.
Account A: $300 monthly deposits, interest rate is 4.2%. Account B: $250 monthly deposits, interest rate is 5.1%. Which account will have a greater value at the end of 15 years?
a. Account A will be greater than Account B.
b. Account B will be greater because the interest rate is higher.
c. They will be worth about the same.
d. Not enough information.
Answer:
A
Step-by-step explanation:
We have to determine the future value of the annuity to determine which account has a greater value
Future value = Amount x annuity factor
annuity factor = Annuity factor = {[(1+r)^n] - 1} / r
Account A = 300 x[ (1.042)^15 - 1 ] / 0.042 = $6097.14
Account B = 250 x[ (1.051)^15 - 1 ] / 0.051 = $5435,42
Account A will be greater

Answer:
3
Step-by-step explanation:
The two quads are of similar, and we know that they are of ratio 1:2, thus
3y+5/7 = 2
y = 3
Answer:
y = 3
Step-by-step explanation:
The figures are similar so the ratios of corresponding sides are equal, that is
[tex]\frac{UR}{DA}[/tex] = [tex]\frac{TS}{CB}[/tex] , substitute values
[tex]\frac{4}{2}[/tex] = [tex]\frac{3y+5}{7}[/tex] ( cross- multiply )
2(3y + 5) = 28 ( divide both sides by 2 )
3y + 5 = 14 ( subtract 5 from both sides )
3y = 9 ( divide both sides by 3 )
y = 3

Given f (x) = 3x and g(x) =
x + 3
Which value is in the domain of fo
fºg?
Click on the correct answer.
-7
3
Answer:
x = 8
Step-by-step explanation:
f(x) = [tex]\sqrt{3x}[/tex]
g(x) = [tex]\frac{1}{x+3}[/tex]
(f o g)(x) = f[g(x)]
= [tex]\sqrt{\frac{3}{x+3} }[/tex]
This function is defined for (x + 3) > 0
(x + 3) - 3 > 0 - 3
x > -3
From the given options x = 8 is the only solution which is greater than -3.
Therefore, x - 8 is in the domain of the given function.

Answer:
2x is less than 8 or B
Step-by-step explanation:
When looking at the number line you got to look to see if the circle is closed or not. In this case it is a closed circle meaning to include the number. Then look at what direction it is going toward. Is it increasing? Is it decreasing? In this case it is decreasing. Meaning that 2x is less than 8
NOT A - Reason why it is not a is because 8 is not included in the range of numbers
NOT C

The farmer owned 100 acres of land. A year later he bought more property and then owned 140 acres. Is this a percent increase or decrease? Find the % change. Round to the nearest whole percent, if necessary.
Answer:
The percentage change (an increase) wa 40%.
Step-by-step explanation:
The beginning number of acres was 100; adding 40 more brought that to 140 acres. This was an increase. Dividing the increase (40) by the starting value (100) yields 0.40. Finally, multiplying this result by 100% yields 40%.
The percentage change (an increase) wa 40%.

The rectangle below has an area of 70 square meters.
Find the dimensions of the rectangle.
(x - 11)
(x - 8)
Answer:
The side lengths are 10 by 7
Step-by-step explanation:
The area of a rectangle is
A = l*w
70 = (x - 11)(x - 8)
FOIL
70 = x^2 -8x-11x+88
Combine like terms
70 = x^2 -19x +88
Subtract 70 from each side
0 = x^2 -19x +88-70
0 = x^2 -19x+18
Factor
What number multiplies to 18 and adds to -19
-18*-1 =18
-18-1 = -19
0=(x-18)(x-1)
Using the zero product property
x-18=0 x-1=0
x=18 x=1
But x cannot x=1 because then the side lengths would be negative
x-18 = 10
x-11 = 7
The side lengths are 10 by 7
use the area of the rectangle to find the area of the triangle 2 ft 9 ft
Answer:
[tex]\Huge\boxed{B}[/tex]
Step-by-step explanation:
Hello There!
The area of a rectangle is equal to length times width
2*9=18 so the area of the rectangle is 18 square feet
If a triangle is formed in a rectangle then that triangle is 1 half of the area of the rectangle
18/2=9 so the area of the triangle is 9 square feet
