Answer:
1. y=5 and x=-5
2. y=2 and x=-4
Step-by-step explanation:
1.y=-5x-19
y=-6x-24
since both equations are equal to y, they are also equal to eachother
-5x-19=-6x-24
addition P.O.E.
x-19=-24
addition P.O.E.
x=-5
substitute x into one equation
y=-5*-5-19
y=6
2. y=-6x-22
y=-3x-10
since both equations are equal to y, they are also equal to eachother
-6x-22=-3x-10
addition P.O.E.
-22=3x-10
addition P.O.E.
-12=3x
division P.O.E.
-4=x
substitute x into one equation
y=-3*-4-10
y=2
Mia has filled 34 of the fish tank with water. If the
tank holds 32 gallons, how many gallons has she
put in the tank?
Answer:
24 gallons
Step-by-step explanation:
"Mia has filled 3/4 (three quarters) of the fish tank with water. How many gallons has she put in the tank to fill it 3/4 full? Let g be the number of gallons. Then:
(3/4)(32 gallons) = number of gallons Mia put into the tank: 24 gallons

Addison has some puzzle books. She will buy 7 new puzzle of books each year.
She will have 43 puzzle books in 5 years.
Rate of change per year____
Initial value____
Help me please :))) <3 ~
Answer:
7
8
Step-by-step explanation:
The rate of change per year is the number of books she gets each year.
The problem states "She will buy 7 new puzzle of books each year."
The rate of change per year is 7.
The initial value is the beginning value.
She gets 7 book each year. In 5 years, she gets 5 * 7 = 35 books.
She will have 35 additional books in 5 years. She will have a total of 43 books in 5 years.
43 - 35 = 8
She started with 8 books.
The initial value is 8.

Sides: a = 6 b = 9 c = 12
Area: T = 26.143
Perimeter: p = 27
Semiperimeter: s = 13.5
Answer:
YES
Step-by-step explanation:
The sum of the lengths of any two sides of a triangle is greater than the length of the third side.
12 + 6 is bigger than 9
12 +9 is bigger than 6
9+6 is bigger than 12
write an equation of the line passing through the point A(8,2) that is perpendicular to the line y=4x-7
Answer:
y - 2 = (-1/4)(x - 8)
Step-by-step explanation:
The slope of the given line is 4. The slope of any line perpendicular to the given line is the negative reciprocal of 4, which is -1/4.
Use the point-slope formula:
y - k = m(x - h), where (h, k) is the given point.
Then: y - 2 = (-1/4)(x - 8)

is y=x^2-4 linear or non linear
Answer:
Non linear, because x is squared. It's a bi-quadratic polynomial, not a linear polynomial.
Answer:
The polynomial y = 2x² - 4 is a bi - quadratic polynomial & hence is a non - linear polynomial.
Find measure FGH circles unit
Answer:
[tex] \huge \orange{m\widehat {FGH} =238\degree} [/tex]
Step-by-step explanation:
Quadrilateral AFGH is inscribed in a circle. So, it is a cyclic quadrilateral. Opposite angles of a cyclic quadrilateral are supplementary.[tex] \therefore m\angle FGH + m\angle FAH = 180\degree [/tex]
[tex] \therefore (21x-2)\degree + (38x +5)\degree = 180\degree [/tex]
[tex] \therefore (21x-2+38x +5)\degree = 180\degree [/tex]
[tex] \therefore 59x+3= 180[/tex]
[tex] \therefore 59x= 180-3 [/tex]
[tex] \therefore 59x= 177 [/tex]
[tex] \therefore x= \frac{177}{59}[/tex]
[tex] \therefore x=3[/tex]
Now, by inscribed angle theorem:
[tex] m\angle FAH = \frac{1}{2} m\widehat {FGH} [/tex]
[tex] (38x +5)\degree = \frac{1}{2} m\widehat {FGH} [/tex]
[tex] 2(38\times 3+5)\degree = m\widehat {FGH} [/tex]
[tex] 2(119)\degree = m\widehat {FGH} [/tex]
[tex] 238\degree = m\widehat {FGH} [/tex]
[tex] \huge \purple {\boxed {m\widehat {FGH} =238\degree}} [/tex]
What is the relationship between factoring and distribution?
Answer:
UwU
Step-by-step explanation:
Use the distributive property to factor a monomial out of a polynomial. Factors are numbers that multiply together to produce another number. For example, 2 and 10 are factors of 20, as are 4 and 5 and 1 and 20. Factoring is the process of breaking a number down into its multiplicative factors.
Answer: Factoring is the opposite of using the distributive property to multiply. If you had: 7(3x + 8), you would distribute the 7 and multiply it both both terms. Factoring reverses that process.
Step-by-step explanation: Hope am right!

To stich a shirt, 2m 15cm cloth is needed. Out of 40m cloth,how many shirts can be stiched and how many will remain?
Answer:
18 shirts can be made and 130 cm of clothes will remain unstitched.
Step-by-step explanation:
Given that,
Total length of the cloth = 40 m = 4000 cm
Amount needed to stitch a shirt = 2m 15cm = 215 cm
Now dividing 4000 by 215 to get the number of shirts that can be stitched and no. of shirts remain. After dividing, we get quotient as 18 and remainder as 130.
So, 18 shirts can be made and 130 cm of clothes will remain unstitched.
from a point P the length of the tangent to a circle is 24 cm and the radius is 7 cm find the distance of P from the centre
Answer:
22.96 cm
Step-by-step explanation:
Let the point of contact of the tangent with the circle be R.
Let the centre of the circle be O.
We are told that from Point P, the length of the tangent is 24 cm.
Thus, PR = 24 cm
Now, the radius will be perpendicular to the tangent at the point of contact with the circle.
Thus, ORP will form a right angle triangle where ∠R = 90°
Since radius = 7 cm, we can use pythagoras theorem to find OP which is the distance of P from the centre.
Thus;
OP = √(24² - 7²)
OP = √527
OP = 22.96 cm

A sequence is given by the function an = 4an-1 . If a1= 3, what is the value of a6 ?
Answer:
3072
Step-by-step explanation:
a1 = 3
an = 4 an-1
so a2 = 4 (a1) = 4*3 = 12
a3 = 4 a2 = 4(12) = 48
a4 = 4*a3 =4*48 =192
a5 =4a4 = 4*192 =768
a6 =4*a5 =4*768 = 3072

Can someone help me , with process to please ?
I will appreciate thank you so much!
Answer:
x = -1
y = 1
Step-by-step explanation:
x + 2y = 1 (Multiply this by -2)
2x + 5y = 3
-2x - 4y = -2
2x + 5y = 3
y = 1
x + 2y = 1
x + 2(1) = 1
x + 2 = 1
x = 1 - 2
x = -1
Answer:
x = -1
y = 1
Step By Step Explanation:
x + 2y = 1
2x + 5y = 3
let x become the subject. use one of the equation.
x = 1 - 2y
substitute into another equation
2(1 - 2y) + 5y = 3
expend the bracket
2 - 4y + 5y = 3
collect like terms
- 4y + 5y = 3 - 2
y = 1
substitute into one of the equation to find x
x + 2y = 1
x + 2 (1) = 1
x + 2 = 1
collect like terms
x = 1 - 2
x = - 1

Kwame and Karen both deposited $2 000 in separate savings accounts.
Kwame's bank pays 3.1% simple interest.
Karen's bank pays 2.7% interest compounded annually.
What will be the combined balance of their accounts after 4 years?
Answer:
2248+2224.91= 4472.91
Step-by-step explanation:
A = $2,248.00
I = A - P = $248.00
Equation:
A = P(1 + rt)
Calculation:
First, converting R percent to r a decimal
r = R/100 = 3.1%/100 = 0.031 per year.
Solving our equation:
A = 2000(1 + (0.031 × 4)) = 2248
A = $2,248.00
The total amount accrued, principal plus interest, from simple interest on a principal of $2,000.00 at a rate of 3.1% per year for 4 years is $2,248.00.
A = $2,224.91
A = P + I where
P (principal) = $2,000.00
I (interest) = $224.91
Calculation Steps:
First, convert R as a percent to r as a decimal
r = R/100
r = 2.7/100
r = 0.027 rate per year,
Then solve the equation for A
A = P(1 + r/n)nt
A = 2,000.00(1 + 0.027/1)(1)(4)
A = 2,000.00(1 + 0.027)(4)
A = $2,224.91
Summary:
The total amount accrued, principal plus interest, with compound interest on a principal of $2,000.00 at a rate of 2.7% per year compounded 1 times per year over 4 years is $2,224.91.
