Jamel wants to buy a PS 5. He found it for $500
with a 30% discount on Black Friday. How much
would he pay before taxes ?..
Answers
Answer:
150
Step-by-step explanation:
its 150 without taxes
Answer:
350
Step-by-step explanation:
Assumung that the $500 is before taxes, Jamel would have to pay $350.
$500 = price before discount
30% = discount
This means that Jamel would be paying 70% of the orginal price, because 30% of it is already taken off.
0.7*500=350

Enter the number that

Answers
Answer:
The distance between the two points is [tex]\sqrt{26}[/tex]
Step-by-step explanation:
The formula of the distance between two points (x1, y1) and (x2, y2) is
d = [tex]\sqrt{(x2-x1)^{2}+(y2-y1)^{2}}[/tex]
∵ The points are (-1, 3) and (4, 2)
∴ x1 = -1 and x2 = 4
∴ y1 = 3 and y2 = 2
→ Substitute them in the formula of the distance above
∵ d = [tex]\sqrt{(4--1)^{2}+(2-3)^{2}}[/tex]
∴ d = [tex]\sqrt{(4+1)^{2}+(-1)^{2}}[/tex]
∴ d = [tex]\sqrt{(5)^{2}+1}[/tex]
∴ d = [tex]\sqrt{25+1}[/tex]
∴ d = [tex]\sqrt{26}[/tex]
∴ The distance between the two points is [tex]\sqrt{26}[/tex]
Your cell phone provider charges a monthly fee of $30. You are also charged $0.07 per minute
for each minute. Last month, Mr. Gonzales' bill was $59.40. Let m represent the total number
of minutes Mr. Gonzales used last month. Use the verbal model below to write an equation.
Answers
Answer:
0.07m + 30 = 59.40
Mr Gonzalez used 420 minutes last month
Step-by-step explanation:
To represent how much money Mr. Gonzales was charged for using minutes, use the term 0.07m.
Then, add 30 to this to represent the monthly fee:
0.07m + 30
Lastly, set this equal to 59.40 because that was his total bill for the month:
0.07m + 30 = 59.40
So, the equation for the situation is 0.07m + 30 = 59.40
Solve for m in the equation:
0.07m + 30 = 59.40
0.07m = 29.40
m = 420
So, Mr Gonzalez used 420 minutes last month.

What is the equation of a line, in point-slope form, that passes through (-8, 1)and has a slope of ?
O y+1=(x - 8)
Oy+8= 5 (1-1)
oy-1-5(x + 8)
Oy-8= + (x+1)
Answers
Answer:
y-1 = 5(x+8)
Step-by-step explanation:
The standard equation of a line in point slope form is expressed as;
y-y0 = m(x-x0)
m is the slope
(x0, y0) is the point
Given
Slope m = 5 (assumed value)
Point (-8,1)
Substitute the given data's into the formula
y -1 = 5(x-(-8))
y-1 = 5(x+8)
Hence the required equation is y-1 = 5(x+8)

A.) This system has no solutions.
Step-by-step explanation:
y = 1/2x + 4
-1/2x + y = -5
-1/2x + (1/2x + 4) = -5
4 = -5
The system has no solutions, if we graph it, we get that it has the same slope with two different y-intercepts, these two are parallel. These two points will never meet at a point.
Answer:
use the relationship between coefficients of a pair of linear equations for no solutions i.e. a1/a2 equal to b1/b2 not equal to c1/c2 .
Here, a is coefficient of x and b is coefficient of y and c is constant term in both equation but make sure that you put the values of a1,a2,b1,b2,c1 and c2 after converting both equation in the form ax+by+c=0 with proper sign and here y=1/2(x) +4 is equation 1 and other is equation 2

Let
x ----> the total number of people
y ----> the time required to fill the stadium

d = vt
where:
v = speed
d = distance
t = time
Based on the formula, each quantity is directionally proportional to each other. Since we don't have enough numbers to work with, we will utilize our concept skills.
If the car travels half the speed, then the car is slowing down and covers a short distance in a certain amount of time than it did originally. So we divide the default distance by 2.
180 / 2 = 90
The new distance so far is 90 miles.
But now it takes the car 3 times as long to get to its destination. The longer it takes, the more distance you will cover. Multiply the current distance by 3.
90 * 3 = 270
The car travels 270 miles.

Solve x2 – 12x + 26 = 0 by completing the square.
Answers
Answer:
6±√10
Step-by-step explanation:
x^2-12x+26=0
x= ± √10 +6
6±√10
The solutions of the given quadratic equation [tex]x^2 - 12x + 26 = 0[/tex] are;
x = 6 + √10 and x = 6 - √10.
To solve the quadratic equation [tex]x^2 - 12x + 26 = 0[/tex]
using completing the square method, follow the steps below.
Move the constant term to the right side of the equation
[tex]x^2 - 12x = -26[/tex]
To find the value that completes the square, divide the coefficient of x by 2 and square it.
[tex](-12/2)^2 = 36[/tex]
Add and subtract the value obtained in step 2 to the left side of the equation
[tex]x^2 - 12x + 36 - 36 = -26[/tex]
Simplify the left side of the equation by factoring the perfect square trinomial
[tex](x - 6)^2 - 36 = -26[/tex]
Add 36 to both sides of the equation to isolate the perfect square trinomial
[tex](x - 6)^2 = 10[/tex]
To Take the square root of both sides of the equation
x - 6 = ±√10
Solve for x
x = 6 ± √10
So, the solutions of the given quadratic equation [tex]x^2 - 12x + 26 = 0[/tex] are x = 6 + √10 and x = 6 - √10.
