7(3 + 4y) - 15y = 73
( Multi-step equations)
show work please and thank you
Answers
Answer:
Step-by-step explanation:
7(3+4y)-15y=73
21 plus 28y-15y=73
21 plus 13y = 73
13y=51
y=4
Step-by-step explanation:
Step 1: Multiply the 7 into the bracket.(make sure that your signs are correct)
Step 2: Minus the 21 from the 73.( Because when you take a value over the equal sign the value's sign changes)
Step 3: Minus 15y from 28y.
Step 4: Divide 52 by 13( because when you take the 13 over it divides ,because on the other side lf the equal the 13 multiples with the y)

The graph below shows the cost of pens based on the number of pens in a pack. What would be the cost of one pen?
A graph is shown with title Purchase of Pens. The horizontal axis label is Number of Pens, and the vertical axis label is Cost in dollars. Points are plotted on the ordered pairs 3, 4.50, and 5, 7.50 and 7, 10.50.
A. $1.50
B. $2.30
C. $6.00
D. $13.50
PLS HELP!!!!!!!!!!!!!!!!!!!! (⊙﹏⊙) (￣_￣|||)
Answers
9514 1404 393
Answer:
A. $1.50
Step-by-step explanation:
You can probably read the cost from the graph. Find the x-axis position corresponding to 1 pen and locate the point on the graph above that position. Then read the y-coordinate (cost) from the vertical axis. It will be sufficiently close to $1.50 that you can easily determine that to be the correct answer choice.
__
Cost per pen is found by dividing cost by pens.
$4.50/(3 pens) = $1.50 /pen*
_____
* /pen would be pronounced, "per pen."

A. 1.50

Anthony is going to invest in an account paying an interest rate of 2.7% compounded quarterly. How much would Anthony need to invest, to the nearest hundred dollars, for the value of the account to reach $130 in 10 years?
Answers
Answer:
$99
Step-by-step explanation:
Given that :
Rate (r) = 2.7% = 0.027 Compounded quarterly
Final amount (A) = $130
Period (t) = 10 years
Principal = invested amount (p) =?
n = number of compounding tines per period = 12/3 = 4
Using the formula :
A = p(1 + r/n)^nt
130 = p(1 + 0.027/4)^(4*10)
130 = p(1 + 0.00675)^40
130 = p(1.00675)^40
130 = p(1.3087766)
P = 130 / 1.3087766
P = 99.329402
P = $99
Answer: 95810
Step-by-step explanation:
Compound interest formula
A=240000\hspace{35px}t=20\hspace{35px}r=0.046\hspace{35px}n=12
A=240000t=20r=0.046n=12

y = - 2 + [tex]\frac{1}{3}[/tex] x
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (0, - 2) and (x₂, y₂ ) = (6, 0) ← 2 points on the line
m = [tex]\frac{0+2}{6-0}[/tex] = [tex]\frac{2}{6}[/tex] = [tex]\frac{1}{3}[/tex]
The line crosses the y- axis at (0, - 2 ) ⇒ c = - 2
y = [tex]\frac{1}{3}[/tex] x - 2 , or
y = - 2 + [tex]\frac{1}{3}[/tex] x
Answer:
Proof
Step-by-step explanation:
"The y-intercept is - 2" and now I think the best way to prove the gradient is to prove it mathematically taking coordinates of the line and using:
[tex]m = \frac{y - y}{x - x} [/tex]
So I'll take the coordinates (6,0) and (0,-2) and substitute them in the formula for the gradient.
[tex]m = \frac{ - 2 - 0}{0 - 6} = \frac{ - 2}{ - 6} = \frac{1}{3} [/tex]

First, find the slope:
The slope is 1/2.
Now we have this much of the equation:
y = 1/2x + b
Plug in the point (0,3) to find the value of b
3 = (1/2)(0) + b
b = 3
Your final equation is y = 1/2x + 3.
Step-by-step explanation:
The equation of the line is y = x/2 + 3 which is passing through the points (-4, 1) and (0, 3) option (B) is correct.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
The straight line is shown in the coordinate plane.
The equation of the line passing through the points:
(-4, 1) and (0, 3)
From the two-point we can find the equation of the line:
y - 3 = (3-1)/(0+4)[x]
y = 2/4[x] + 3
y = x/2 + 3
Thus, the equation of the line is y = x/2 + 3 which is passing through the points (-4, 1) and (0, 3) option (B) is correct.
