Answer:
see below
Step-by-step explanation:
We want to solve each equation for y, so y must be alone on one side of the equation.
a) 10x + 5y = 20
Subtract 10x from both sides.
5y = 20 - 10x
Place the x term in front to follow y = mx + b form.
5y = -10x + 20
We want to isolate y completely, so divide both sides by 5. On the right side, be sure to divide each component by 5.
5y/5 = -10/5x + 20/5
y = -2x + 4
This equation is in slope-intercept form.
b) 3x - 2y = 10 + 4x
We can see that y is negative in this original equation. Let's add 2y to both sides to make y positive.
3x = 10 + 4x + 2y
Now we want to isolate y, so subtract 4x from both sides.
3x - 4x = 10 + 2y
Simplify.
-x = 10 + 2y
Isolate y further by subtracting 10 from both sides.
-x - 10 = 2y
Again, we want to isolate y completely, so divide both sides by 2. On the left side, be sure to divide each component by 2.
-x/2 - 10/2 = 2y/2
-1/2x - 5 = y
This looks backwards (although it is in slope-intercept form), so let's rearrange it just to make it more clear.
y = -1/2x - 5
This equation is in slope-intercept form.

!!NEED THIS NOW PLS!!Expand the logarithmic expression
Answer:
B)
Step-by-step explanation:
we are given a logarithmic expression
we want to expand it
in order to do so we can consider using
exponent logarithm propertydivision logarithm propertyrecall that,
[tex] \displaystyle \sqrt{x} = {x}^{ \frac{1}{2} } [/tex]
thus rewrite
[tex] \displaystyle \log_{ \sigma} \bigg( \frac{57}{74} \bigg) ^{ \large\frac{1}{2} } [/tex]
use division logarithm property
[tex] \displaystyle \log_{ \sigma}(57) ^{ \large\frac{1}{2} } - \log_{ \sigma}(74)^{ \large \frac{1}{2} } [/tex]
use exponent logarithm property:
[tex] \displaystyle \frac{1}{2} \log_{ \sigma}(57) ^{ \large } - \frac{1}{2} \log_{ \sigma}(74)^{ \large } [/tex]

stay safe healthy and happy.i do t really know how to do this pls help
Answer:
for number 5 Subtract 18 from both sides of the equation
4+18−18=30−18
for number 1 Subtract 7 from both sides of the equation
so number 3 subtract 3 from each side and so on hope it helps
im not sure how to explain it but--
for example.. the first one
1) y + 7 = 12
first, you subtract 7 from both sides
so-- you'll subtract 7-7 on the left and 12-7 from the right
now, you have y by itself since 7-7 = 0
y = 12-7, or y = 5
also its important to note that when the equation is like 2) and uses subtraction (x-4) instead of addition (y +7)-- then you add to both sides
so for 2)-- you'd add 4 to both sides for 4 to cancel out to equal 0
your goal is always to isolate the variable on one side

In Frank's piggy bank, there are only quarters
and dimes. He has 37 coins, and has a total of
$5.50. How many quarters does he have?
Answer:
12 quarters
Step-by-step explanation:
number of quarters ---------x
number of dimes ------------y
therefore, x + y = 37---------------times 10 both sides --------10x + 10y = 370-------equation 1
0.25x + 0.1y = 5.5 -----times 100 both sides -------25x + 10y = 550 ------equation 2
equation 2 minus equation 1 is 25x + 10y - 10x - 10y = 550 - 370 ------ 15x = 180 -------x = 12
there are 12 quarters

A savings account starts with $250. It earns $30 in 2 years. Find the
rate of interest
Answer:
The annual interest rate is 6%
Step-by-step explanation:
Use the formula for simple interest: i = prt.
Set i = prt equal to $30: $30 = prt
Solve this for r:
$30
r = -------------- = ($30) / ($500) = 0.06
$250(2)
The annual interest rate is 6%

At school, 588 students bought a school
shirt, and 147 students did not. What
percent of the students bought a school
shirt?
Answer:
80%
Step-by-step explanation:
Step 1: Add the given data
588 + 147 = 735
Step 2: Divide the number of students who bought a school shirt by the total number of students
588 ÷ 735
= [tex]\frac{735}{588}[/tex]
= 0.8
Step 3: Convert the decimal to fraction
0.8 = 80% (Move the zero 1 place behind the number and remove the ".")
Or
0.8 × 100 = 80%
Therefore, 80% of students bought a school shirt.

In a regular tessellation 3,4,6 sides can be tessellating regular
polygon.
What is regular polygon?A normal tessellation is one made the use of only one regular polygon. A semi-normal tessellation uses or extra ordinary polygons. Triangles and squares, for example, shape ordinary tessellations and octagons and squares for a semi-normal tessellation.
First of all, there are handiest 3 normal tessellations which can be triangles, squares, and hexagons. To make a ordinary tessellation, the inner angle of the polygon has to be a diviser. that is due to the fact the angles need to be introduced as much as so it does now not leave any gaps.
A polygon having identical facets of identical lengths are known as everyday polygons. A ordinary polygon is a polygon that is equiangular i.e. all the angles are equal in measure and equilateral i.e. all facets have the equal length.
A line of symmetry is a line that can be attracted to divide a parent into same halves. A determine has line symmetry or reflection symmetry while it could be divided into identical halves that match. A discern has mirrored image symmetry if it could be meditated throughout a line and look exactly the same as it did earlier than the reflection.

Find the slope of the line that passes through the points given in the table.
Answer:
-1
Step-by-step explanation:
The change in y between x=-1 and x=2 is -3 and -3/3=-1 so the slope is -1
Answer:
-1
Step-by-step explanation:
Use any 2 points on the line.
Let's use (10, -6) and (2, 2).
slope = (difference in y)/(difference in x)
slope = (-6 - 2)/(10 - 2)
slope = -8/8
slope = -1
