Answer:
-7, but it doesn't make sense bc age can't be a negative. But based on how this is said it sounds like -7
Step-by-step explanation:
paloma's age = p
2( p + 15 ) = 16
2p + 30 = 16
-30 -30
2p = -14
/2 /2
p = -7

Step-by-step explanation:
what must be the value of a and b for PQRS to be a parallelogram?
Answer:
a = 2
b = 4
Step-by-step explanation:
In parallelogram opposite sides are equal.
4a + b = 2a + 8
4a - 2a + b = 8
2a + b = 8 -----------------(I)
b = 8 - 2a
11b - 10a = 6b
11b - 6b -10a = 0
5b - 10a = 0 ---------(II)
Substitute b = 8 - 2a in equation (II)
5*(8-2a) - 10a = 0
5*8 - 2a * 5 - 10a = 0
40 - 10a - 10a = 0
40 - 20a = 0
-20a = - 40
a = -40/-20
a = 2
Plugin a = 2 in equation (I)
2*2 + b = 8
4 + b = 8
b = 8 -4
b = 4

Find the area of the triangle.
C = 133.5°, a = 45.7 ft and b = 37.1 ft
The area is
square ft.
(Simplify your answer. Type an integer or a decimal. Roun
Answer:
i think the answer is area = 1695.47 ft squared
Step-by-step explanation:
just do 45.7 x 37.1 since you’re finding area of a SQUARE which has all equal sides.
HELPPP PLEASEEE!!! Write the equation in slope-intercept form of the line that passes through (6, -11) and is parallel to the graph of y=−2/3x+12. Show work
Answer:
y=-2/3x-7
Step-by-step explanation:
parallels have the same slope just different y ints
to find what the y int is i just graphed the point (6,-11) to a calculator and made an equation with a slope of -2/3 and plugged in different y ints to get this

5x - y -= 3
x + 2y = 5
Answer:
1)y=-3+5x
2)y=5/2-1/2x
Step-by-step explanation:
for both equations
1) get your y by it self (subtract -5x and your new equation is now -y=-5x+3)
2)(reminder y can't be negative if it is negative) then you divide by -1 of both sides
3) your equation should now be y=5x-3

Andrea works as a cashier in a music store. A customer wants to buy a CD that is
on sale for 15% off the regular price of $14.00. This means she will pay 85% of
$14.00. How much will Andrea pay?
Answer:
$11.90
Step-by-step explanation:
first you change the percent to a decimal by moving the decimal two places and then multiply.
you multiply .85 and 14.00= 11.90
Answer:
$11.9
Step-by-step explanation:
The regular cost of the CD = $14:00
The discount she gets = 15%
So, 15% of $14 = 2.1
= $14 - $2.1 = $11.9
Another method:
Or u can take 85% of $14 and u will get the immediately
85% of $14 = $11.9

What is the rate of this answer ??
Answer:
Option (4)
Step-by-step explanation:
Let the input output values of the table are represented by the equation,
y = mx + b
Here m = rate
b = y-intercept
Since, at x = 0, y = -1 [Point given in the table]
y-intercept 'b' = 0
Rate = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
Where [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] are two points given in the table.
If the points are (-2, -5) and (-1, -3),
Substitute the values in the formula,
Rate = [tex]\frac{(-5)-(-3)}{(-2)-(-1)}[/tex]
= [tex]\frac{-5+3}{-2+1}[/tex]
= 2
Therefore, Option (4) will be the answer.

Answer: the equation of this parallel line would be: Answer: y = 5x - 6
Step-by-step explanation:
Slope of the parallel lines are same
So, m= 5
(3,9)
Equation: y - y1 = m(x -x1)
y - 9 = 5(x - 3)
y - 9 = 5x - 3*5
y -9 = 5x -15 {add 9 to both sides}
y - 9 + 9 = 5x - 15 + 9
y = 5x - 6

The perimeter of a right triangle is 60 feet and the area is 150 square feet. If the lengths of the sides of the triangle are each multiplied by 10, what is the perimeter of the new right triangle? A. 500 ft. B. 600 ft. C. 7120 ft. D. 8640 ft.
Answer:
B. 600 ft
Step-by-step explanation:
The formula for the Perimeter of a right triangle = Side a + Side b + Side c
The perimeter of a right triangle is 60 feet
If the lengths of the sides of the triangle are each multiplied by 10, what is the perimeter of the new right triangle?
Hence, the perimeter of the new right triangle = 10 × 60ft
= 600ft
Option B is the correct Option.
Answer:
600
Step-by-step explanation:
This relation is an inverse variation. {(–1, 8), (4, –2), (–2, 4)} Which equation represents this relation?
Answer:
[tex]y = -\frac{8}{x}[/tex]
Step-by-step explanation:
Given
Inverse Variation:
[tex]Points: \{(-1, 8), (4, -2), (-2, 4)\}[/tex]
Required
Determine the equation of the relation
An inverse relation is represented as:
[tex]y = \frac{k}{x}[/tex]
Where k = constant of variation
Make k the subject:
[tex]k = xy[/tex]
When x = -1, y = 8
So, we have:
[tex]k = -1 * 8[/tex]
[tex]k = -8[/tex]
When x = 4, y = -2
[tex]k = 4 * -2[/tex]
[tex]k = -8[/tex]
When x = -2, y = 4
[tex]k= -2 * 4[/tex]
[tex]k = -8[/tex]
From above calculations, we've established that:
[tex]k = -8[/tex]
Substitute -8 for k in [tex]y = \frac{k}{x}[/tex]
[tex]y = \frac{-8}{x}[/tex]
[tex]y = -\frac{8}{x}[/tex]
Hence, the equation is:
[tex]y = -\frac{8}{x}[/tex]

Yoko needs 300 copies of her resume printed. Dakota printing charges 19.50$ for the first 200 copies and 9$ for every 100 additional copies. If the number of sets of 100 resumes is represented by r, express the cost of the resumes c(r) algebraically as a piecewise function How much will 300 copies cost, including a sales tax of 4 1/2%? Round to the nearest cent.
Answer:
A. c(r)=$19.5 if r < 2
c(r)=$19.5+(r-2) ($9) (1.045) if r ≥ 2
B. $29.78
Step-by-step explanation:
A. Based on the information given if we are to express the cost of the resumes which is c(r) algebraically as a piecewise function what we would have will be:
c(r)=$19.5 when r represent an INTERGER and is less than 2
c(r)=$19.5+(r-2) ($9) (1+0.045)
c(r)=$19.5+(r-2) ($9) (1.045) when r represent an INTERGER and is greater than 2
Therefore to express the cost of the resumes c(r) algebraically as a piecewise function will be: c(r)=$19.5 if r < 2
c(r)=$19.5+(r-2) ($9) (1.045) if r ≥ 2
B. Calculation for How much will 300 copies cost, including a sales tax of 4 1/2%
Cost of 300 copies=($19.5+$9)+($19.5+$9) (0.045)
Cost of 300 copies=$28.5+$28.5(0.045)
Cost of 300 copies=$28.50+$1.28
Cost of 300 copies=$29.78
Therefore How much will 300 copies cost, including a sales tax of 4 1/2% will be $29.78
