Alexis opened a savings account with a $120 deposit. Each week she will put $20 into the account. The equation that gives the total amount t in her account is t 120 20w, where w is the number of weeks since she opened the account. How much money will Alexis have in her savings account after 5 weeks?
Answers
Answer:
The amount of money Alexis will have in her savings account after 5 weeks is $ 220.
Step-by-step explanation:
The equation that gives the total amount t in her account is t=120+20w, where w is the number of weeks since she opened the account.
To calculate the amount of money Alexis will have in her savings account after 5 weeks, you replace the number of weeks w since she opened the account by 5:
t=120+20*5
Solving, you get:
t=120+100
t=220
The amount of money Alexis will have in her savings account after 5 weeks is $ 220.

Determine if (2,4) is a solution to this inequality: y < 2x + 2. Explain your reasoning.
Answers
Answer:
Yes
Step-by-step explanation:
To check if (2,4) is a solution to the inequality, y<2x+2, substitute the values of x and y in the inequality and see if it holds good for those values
y=4, x=2
Let's see if 4<2*2+2 => 4<4+2 => 4<6
And the inequality is true. So, (2,4) is a solution to this inequality

Write a program that will solve a quadratic equation: ax2 + bx + c = 0. The program must ask the user to enter the values for a, b and c. It should then determine the discriminant of the parabola and based on the discriminant it should display the real roots: Discriminant = b2 - 4ac > 0 means there will be two distinct real roots. Discriminant = b2 - 4ac = 0 means there will be only one real root. Discriminant = b2 - 4ac < 0 means there will be no real roots. Use the if - then else structure in your program to decide the outcome of the program. User must then use the quadratic equation to solve for x: = − ± √ −
Answers
Answer:
x= -b ±√b²- 4ac/2a
Step-by-step explanation:
ax2 + bx + c = 0
Dividing the quadratic equation by a gives
x2 + b/ax + c/a = 0
x2 + b/ax = - c/a
Applying the square formula
(x)^2 + 2(x) (b/2a) + (b/2a)^2= + (b/2a)^2- c/a
(x+b/2a)^2= b²/4a² - c/a
(x+b/2a)^2= b²/4a² - 4ac/4a²
(x+b/2a)^2= b²- 4ac/4a²
Taking square root of both sides gives
(x+b/2a)= ±√b²- 4ac/2a
x= -b/2a±√b²- 4ac/2a
x= -b ±√b²- 4ac/2a
This is called the quadratic formula and it can solve the value for x for the given value of a, b and c for the quadratic equation.
From this it is concluded that
Discriminant = b2 - 4ac > 0 means there will be two distinct real roots. Discriminant = b2 - 4ac = 0 means there will be only one real root. Discriminant = b2 - 4ac < 0 means there will be no real roots.
This is because a square root of a value greater than 0 is possible and gives two values for roots of x.
The square root of a value less than 0 gives a negative number and therefore the roots are an imaginary number.
The square root of a value greater equal to 0 gives a zero leaving behind only one real root.

Answers
Answer:
3/4 quarts of yellow paint is needed
Step-by-step explanation:
From the question, we are told that:
In order to make purple he must mix red and blue paint together at a ratio of 2 quarts red to 1 quart of blue.
3 quart of Purple paint mix requires 2quarts of red paint and 1 quart of blue paint.
We are also told that:
When George wants to make brown paint he must mix purple and yellow paint together in a 1:1 ratio.
This means 1 Purple paint to 1 Yellow paint
4/4 quarts of Yellow paint = 1 yellow paint
3/4 quarts of Yellow paint = 3/4 quarts of purple paint

Step-by-step explanation:
hope this helped and is that iready??
The remainder of 74 divided by 7 is 4.
What is Division?Division is one of the operation in mathematics where number is divided into equal parts as that of a definite number.
When a number is divided by another number, the number which is being divided is the dividend. Divisor is the number which divides the dividend.
Quotient is the value after the division process.
Remainder is the remaining value after the division.
If the dividend is completely a factor of divisor, remainder will be zero.
Otherwise there will be a non zero number as the remainder.
74 is not a multiple of 7.
70 is the multiple of 7 which is closest to 74.
Remainder = 74 - 70 = 4
Hence the remainder is 4.

Answers
Answer:
50mStep-by-step explanation:
Given the dimension
Length of the rectangle = 8cm
Width = 5cm
Note that when the scale was 1:7, syla multiplied the width by a factor of 7 i.e 5*7 = 35m
If syla changes the the scale to 1 cm : 10 m for the rectangle, then the width of the shorter side will be multiplied by a factor of 10 due to the change in scale i.e;
5 * 10 = 50m
Hence the width of the new stage will be 50 m

Answers
Answer:

Step-by-step explanation:
y=10x+28
y=(10*-2)+28
y=-20+28

The linear equation of the line is y + 2 = 10(x - 8)
How to determine the line equation?The slope is given as:
m = 10
The point is given as:
(x1, y1) = (8, -2)
The equation in point slope form is calculated as;
y - y1 = m(x - x1)
So, we have:
y + 2 = 10(x - 8)
