What’s the difference? (6d+5)-(2-3d)=
Answer:
9d+3
Step-by-step explanation:
Distribute the Negative Sign:
=6d+5+−1(2−3d)
=6d+5+(−1)(2)+−1(−3d)
=6d+5+−2+3d
Combine Like Terms:
=6d+5+−2+3d
=(6d+3d)+(5+−2)
=9d+3

Without calculating, how do you know that the equation |4x - 71 = -1 has no solution?
Answer:
See Explanation
Step-by-step explanation:
Given
[tex]|4x - 7| = -1[/tex]
Required:
How do you know, it has no solution
The expression on the left-hand side is an absolute function and the result is always positive.
However, the expression on the right-hand side shows a negative sign.
The negative sign is on the contrary to what an absolute value represent.
Hence, it has no solution.
A line passes through the points (0,1) and (13,-3). What is it’s equation in slope intercept form.
[tex]\huge\boxed{y=-\frac{4}{13}+1}[/tex]
First, let's find the slope ([tex]m[/tex]) of the line using the two points:
[tex]\begin{aligned}m&=\frac{y_2-y_1}{x_2-x_1}\\&=\frac{-3-1}{13-0}\\&=\frac{-4}{13}\\&=-\frac{4}{13}\end{aligned}[/tex]
Now, we'll use point-slope form using the first point and the slope to get an equation for the line.
[tex]\begin{aligned}y-y_1&=m(x-x_1)\\y-1&=-\frac{4}{13}(x-0)\end{aligned}[/tex]
Now, we just need to get the equation to slope-intercept form, which is [tex]y=mx+b[/tex].
[tex]\begin{aligned}y-1&=-\frac{4}{13}x\\y&=-\frac{4}{13}x+1\end{aligned}[/tex]

Answer:
168 square feet
Step-by-step explanation:
The model has shading in groups of 10 where possible. This makes it relatively easy to find the partial products and add them up.
(10 +4)(10 +2) = 10·10 + 4·10 +10·2 + 4·2
= 100 +40 +20 +8
= 168 . . . . square feet

7y+7x=-21
Solve for y
Answer:
-10
Step-by-step explanation:
add these two equations together to get rid of y. This gives you
x = 7
then plug x back into either equation and you can solve for y !

Baseball hat is on sale for 15% off, which is $2.70. How much does the baseball hat cost at full price?
Answer:
27.9 dollars
Step-by-step explanation:
2.70= 15 percent
2.70x2=5.4=30 percent
5.4+2.70=8.1=45 percent
8.1x2=16.2=95 percent
95 percent + 15 percent=18.9
18.9=105 percent
in order to subtract 5 percent we need to find 5 percent by dividing 2.70 by 3
which = .9
18.9+9=27.9
100 percent is 27.9 dollars

Explain how you could use the information that all circles are similar to show that the value of pi is a constant.
Answer:
defined as the ratio of a circle's circumference to its diameter, is constant. That is, it does not vary given circles of differing size. This claim is equivalent to saying "all circles are proportional" or "all circles are similar."
Answer:
The proof that πk(C1)=πk(C2) of course would just apply the similarity of polygons and the behavior of length and area for changes of scale. This argument does not assume a limit-based theory of length and area, because the theory of length and area for polygons in Euclidean geometry only requires dissections and rigid motions. Any polygonal arc or region can be standardized to an interval or square by a finite number of (area and length preserving). Numerical calculations involving the πk, such as ratios of particular lengths or areas, can be understood either as applying to equidecomposability classes of polygons, or the standardizations. In both interpretations, due to the similitude, the results will be the same for C1 and C2.
