Answer:
x = - 11/4
Step-by-step explanation:
20- 3x = 9 - 7x
Add 7x to both sides
20 - 3x + 7x = 9 - 7x + 7x
20 + 4x = 9
Now,Subtract 20 from both sides
20 -20 + 4x = 9 - 20
4x = -11 {Divide both sides b 4}
x = -11/4
Answer:
= -11/4
Step-by-step explanation:
Rearrange terms
−3+20=9−7
− 3 + 20 = − 7 + 9
Subtract 20 from both sides of the equation
− 3 + 20 = − 7 + 9
− 3 + 20 − 20 = − 7 + 9 − 20
Simplify / Subtract the numbers
− 3 = − 7 − 1 1
Add 7 7x 7x to both sides of the equation
− 3 = − 7 − 1 1
− 3 + 7 = − 7 − 1 1 + 7
Simplify / Combine like terms
4 = − 1 1
Divide both sides of the equation by the same term
4 = −11
4/4 = -11/4
Simplify / Cancel terms that are in both the numerator and denominator
= -11/4

Find the values of x
when y = 1
Step-by-step explanation:
when y=1 then,
y=1+X
X=1-y .
I'm assuming the equations are o that you solve in your own:
x = y + 1 = 1+1 = 2
x = y -1 = 1-1 = 0
x = 1*y = 1*1 = 1
x = y*1 = 1*1 = 1
x = y/1 = 1/1 = 1
x = 1/y = 1/1 = 1

What is an equation of the line that passes through the points (0,7) and (5,4? Put your answer in fully reduced form.
Answer (assuming it can be in slope-intercept format):
[tex]y = -\frac{3}{5} x+7[/tex]
Step-by-step explanation:
When knowing the y-intercept of a line and its slope, we can write an equation representing it in slope-intercept form, or [tex]y = mx + b[/tex].
1) First, find the slope of the equation. Use the slope formula, [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex], to find the slope. Substitute the x and y values of the given points into the formula and simplify:
[tex]m = \frac{(4)-(7)}{(5)-(0)} \\m = \frac{4-7}{5-0} \\m = \frac{-3}{5}[/tex]
Thus, the slope is [tex]-\frac{3}{5}[/tex].
2) Usually, we would have to use one of the given points and the slope to put the equation in point-slope form. However, notice that the point (0,7) has an x-value of 0. All points on the y-axis have an x-value of 0, thus (0,7) must be the y-intercept of the line. Now that we know the slope of the line and its y-intercept, we can already write the equation in slope-intercept format, represented by the equation [tex]y = mx + b[/tex]. Substitute [tex]m[/tex] and [tex]b[/tex] for real values.
Since [tex]m[/tex] represents the slope, substitute [tex]-\frac{3}{5}[/tex] in its place in the equation. Since [tex]b[/tex] represents the y-intercept, substitute 7 in its place. This gives the following equation and answer:
[tex]y = -\frac{3}{5} x+7[/tex]

Howard Earned a total of 12$ by selling 8 cups of lemonade. How many ups of lemonade does Howard need to sell in all to earn 21$?
Answer:
Step-by-step explanation:
(12 dollars)/(8 cups) = (12/8 dollars)/cup = (1.5 dollars)/cup
21 dollars × (1 cup)/(1.5 dollars) = 21/1.5 cups = 14 cups
Solve the following linear equation for x
5x−2+x=9+3x+10
Answer:
x = 7
Step-by-step explanation:
5x - 2 + x = 9 + 3x + 10
5x + x - 2 = 9 + 10 + 3x
5x + x - 3x - 2 = 9 + 10 + 3x - 3x (substracted 3x from both sides)
3x - 2 = 19
3x = 19 + 2
3x = 21
x = 21 : 3
x = 7

Answer:
(7, 2).
Step-by-step explanation:
The median from A intersects BC at it's midpoint.
To find the midpoint of BC:
This is (x1, y1) where x1 = (sum of the x_values of B and C) / 2) and where y1
= (sum of the y_values of B and C) / 2)
This is (2+12)/2, (1 + 3)/2
= (7, 2).
Talha had $150. He spent 35% of his money on clothes and 15% on Perfumes. How much money did he spend on the two items?
$60
$75
$50
$85
Answer:
$75
Step-by-step explanation:
150 x 0.35 = 52.50
150 x 0.15 = 22.50
(or do 50% of whole total)
22.50 +52.50 = $75
Answer:
75
Step-by-step explanation:
since he spent a total of 50% of his money (35%+15%), then 50% of 150 is 75
Jenny is 9 years younger than Sammie. Five years ago, Sammie was four times older
than Jenny. How old is each now?
Answer:
Jenny's age = 8 yr
Sam's age = 17 yr
Step-by-step explanation:
Let x = Jenny's age now
then x + 9 = Sam's age now
x - 5 = Jenny's age 5 years ago
x + 9 - 5 = x + 4 = Sam's age 5 years ago
4(x - 5) = x + 4
4x - 20 = x + 4
3x = 24
x = 8 = Jenny's age now
x + 9 = 8 + 9 = 17 Sam's age now
Check: 5 yrs ago Jenny was 3 and Sam was 12
4(3) = 12, so the answer is correct.

State the ex and Y intercepts for the given function and then graph the function 2X-3Y=6
Answer:
a) (3, 0), (0, -2)
b) see below
Step-by-step explanation:
The x-intercept is found by setting y=0 and solving for x:
2x = 6
x = 6/2 = 3 . . . point (3, 0), x-intercept
The y-intercept is found by setting x=0 and solving for y:
-3y = 6
y = 6/-3 = -2 . . . point (0, -2), y-intercept
__
The graph is the line through these points.

A map of a public park shows a circular pond. There is a bridge along a diameter of the pond that is 0.85 mi long. You walk across the bridge, while your friend walks halfway around the pond to meet you at the other side of the bridge. How much farther does your friend walk?
Answer: 0.49 mi
Step-by-step explanation:
First find the half circumference of the circular pond as this will show the total distance your friend has to walk:
= (π * diameter) / 2
= (22/7 * 0.85) / 2
= 1.34 mi
Your friend is going to walk 1.34 and you will walk 0.85.
Difference is:
= 1.34 - 0.85
= 0.49 mi
Find the point(s) of intersection between the quadratic function y = x + 4x + 4 and the linear function y = 2x+4.
Answer:
(0, 4)
Step-by-step explanation:
To find the intersection of two lines, we want to find the value when they equal each other. To do this, we want to set the equations equal to each other.
First, let's simplify y = x + 4x + 4 by combining the x's.
y = 5x + 4
Now let's set the equations equal to each other. Since they both equal y, we can set the opposite sides equal to each other.
5x + 4 = 2x + 4
Now you want to combine the terms.
[subtract 4] 5x = 2x
[subtract 2x] 3x = 0
Now you want to isolate the x.
[divide by 3] x = 0
Now we want to find y by plugging x = 0 back into the equations.
y = 5(0) + 4
[multiply] y = 0 + 4
[add] y = 4
Check this with the other equation.
y = 2(0) + 4
[multiply] y = 0 + 4
[add] y = 4
Your answer is correct!
(0, 4)
