write an equation of the line that passes through (-2, 3) and is arallel to the line y=2x-4
Answer:
y=2x+7
Step-by-step explanation:
you would substitute so x=-2 and y=3
All lines parralel always have the same x so
y=2x-c (c means crossing point of y)
then substitute
3=(2x-2)-c
3=-4-c
c= +7
so just put in the equation and the answer is:
y=2x+7

Can someone help me, please?
Answer:
Inequality
[tex]-22<m<12[/tex]
Interval Notation
[tex](-22,12)[/tex]
Reasoning:
First of all, subtract nine on both sides.
[tex]| m + 5|<17[/tex]
Now make two equations
[tex]|m+5|=-17[/tex]
[tex]m=-22[/tex]
[tex]|m+5|=17[/tex]
[tex]m=12[/tex]
Now you can make an inequality for m:
[tex]-22<m<12[/tex]

HELPP YALL! ILL MARK BRAINIEST!!! LOOK AT PICTURE!!!
Answer:
x=11
y=118
Step-by-step explanation:
pls can i have brainliest if im right
Answer:
x = 34°
y = 118°
Step-by-step explanation:
As ∠y and 62° are on the same line but lines P and Q are parallel to each other, they both add up to 180:
y + 62 = 180
y = 180 - 62
y = 118°
As this angle and 4x - 18 are corresponding angles, they both equal the same so:
4x - 18 = 118
4x - 18 + 18 = 118 + 18
4x = 136
[tex]\frac{4x}{4} = \frac{136}{4}[/tex]
x = 34°
Hope this helps!

plz help!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Answer:
Step-by-step explanation:
Use DESMOS to plot both lines (attached).
If you make your own lines on the graph paper, pick two points for each line and connect them with a ruler. Both are straight lines, so we only need two points.
Pick any two values of x and solve each equation for y. I picked x = 1 and 3
EQ1: y=2x-2
EQ2: y=-x+4
Value of y EQ1 EQ2
x =1 0 3
x =3 4 1
Plot the points (1,0) and (3,4) for EQ1.
Do the same for EQ2: (1,3) and (3,1)
The attached graph shows these points. Note that one can draw stright lines for both equations using only these two points.
in a car park 2/3 of the cars are red
1/5 of the cars are blue
What fraction of the cars are red or blue ?
Answer:
13/15
Step-by-step explanation:
"Or" in probability means to add. Therefore, we would do 2/3 + 1/5:
First, we need a common denominator: 2/3 + 1/5 → 10/15 + 3/15 (I multiplied the first fraction by 5/5 and the second fraction by 3/3).
Now, we can add the numerators: 10/15 + 3/15 = 13/15.
Hope this helps!
Find the 71st term. 8, 14, 20, 26, ...
Answer:
The 71st term is 428.
Step-by-step explanation:
Use Arithmetic Explicit formula:
f(n) = f(1) + (n - 1) d
Solve:
f(71) = 8 + (71 - 1) 6
f(71) = 8 + (70) 6
f(71) = 8 + 420
f(71) = 428

Use elimination to solve the system of equations,
5x - 6y = 11
-7x + 5y = 5
Answer:
x = -5
y = -6
Step-by-step explanation:
5x - 6y = 11
-7x + 5y = 5
We could eliminate the 'y' by multiplying the first equation by 5 and the second equation by 6 to get the following:
5(5x - 6y) = 11(5) → 25x - 30 y = 55
6(-7x + 5y) = 5(6) → -42x + 30y = 30
Now we can add the two equations to get:
-17x = 85
x = -85/17 which is x = -5
Now we can plug in -5 into the first equation to solve for 'y':
5(-5) - 6y = 11
-25 - 6y = 11
-6y = 36
y = -6
CHECK:
-7(-5) + 5(-6) should equal 5
35 + (-30) = 5
5 = 5

pasagot please
answer it please
Answer:
Step-by-step explanation:
Let's start by looking at the graph of the two equations.
Since you are not looking for where the lines cross, I have chosen any 3 points for each equation almost randomly. I have not used either the x or y intercepts except once.
As a sample for the method of calculation
Let x -2y = 4
Let x = -2. Find y and put it in the table
-2 - 2y = 4 Add 2 to both sides
-2+2-2y = 4 + 2 Combine
-2y = 6 Divide by -2
y = 6/-2
y = - 3
Put that in the table under the first equation.
The other 5 points are done the same way.

Jane works at a high-end jewelry store. She earns an hourly wage of $10.50, plus a 6% commission on any item she sells. One weekend, Jane works for 5 hours on Saturday and 9 hours on Sunday. She sells $650 worth of jewelry. How much money does she earn that weekend?
Answer:
$186
Step-by-step explanation:
hourly wage: $10.50/hour
commission: 6%
5 hours + 9 hours = 14 hours
14 hours × $10.50/hour = $147
6% of $650 = 0.06 × $650 = $39
total: $147 + $39 = $186

Find the value of y to the nearest tenth.
Step-by-step explanation:
the easiest approach seems to be the law of sines :
a/sin(A) = b/sin(B) = c/sin(C)
where the sides and the angles are always opposite of each other.
we have here a right-angled triangle, so the angle opposite of 10 is 90 degrees.
10/sin(90) = 10/1 = 10 = y/sin(37)
y = 10×sin(37) = 6.018150232 ≈ 6.0
Solve the equation: [tex]x^{2} +5x+6=0[/tex]
I know [tex]x^{2} +5x+6=(x+3)(x+2)[/tex] (that was part a) but I don't know where to go from here!
Step-by-step explanation:
but then you did already the most work.
because just think : when is the expression
(x+3)(x+2) equal to 0 ?
only, if at least one factor of the multiplication is equal to 0.
you know, for example, 5×0 = 0, or 0×3 = 0.
that means either (x+3) or (x+2) must be 0.
x + 3 = 0
x = -3
and
x + 2 = 0
x = -2
and there you have it.
a quadratic equation (with the highest x exponent is 2) has 2 solutions for being 0.
and this one here has the 2 solutions
x = -3 and
x = -2
again, by finding the factors you did already the biggest and most difficult part yourself. congratulations !

The credit remaining on a phone card is a linear function of the total calling time made with the card( in minutes). The remaining credit after 34 minutes of calls is $25.58, and the remaining credit i go after 48 minutes of calls is $23.76. What is the remaining credit after 50 minutes of calls
Answer:
23.5
Step-by-step explanation:
(23.76-25.58)/(48-34) = -0.13
-0.13 * 2 = -0.26
23.76 - 0.26 = 23.5
Sean bought 1.8 pounds of gummy bears and 0.6 pounds of jelly beans and paid $10.26. He went back to the store the following week and bought 1.2 pounds of gummy bears and 1.5 pounds of jelly beans and paid $15.09. What is the price per pound of each type of candy?
Answer:
1 pound of gummy bears = $3.20
1 pound of jelly beans = $7.50
Step-by-step explanation:
1.8 pounds of gummy bears + 0.6 pounds of jelly beans
= $10.26
1.2 pounds of gummy bears + 1.5 pounds of jelly beans
= $15.09
2.5 × (1.8 pounds of gummy bears + 0.6 pounds of jelly beans) = 2.5 × $10.26
--> 4.5 pounds of gummy bears + 1.5 pounds of jelly beans = $25.65
(4.5 pounds of gummy bears + 1.5 pounds of jelly beans) - (1.2 pounds of gummy bears + 1.5 pounds of jelly beans) = 3.3 pounds of gummy bears
3.3 pounds of gummy bears
= $25.65 - $15.09
= $10.56
1 pound of gummy bears
= $10.56 ÷ 3.3
= $3.20
1 pound of jelly beans
= [$10.26 - ($3.20 × 1.8)] ÷ 0.6
= $4.50 ÷ 0.6
= $7.50

Answer:
9x(3x-2) (3x+2)
Step-by-step explanation:
[tex]81x^{3}-36x[/tex]
9(9x³ - 4x)
9x(9x² - 4)
Since both terms are perfect squares factor using the difference of squares formula, a² - b² = (a + b) (a - b)
Therefore, 9x(3x-2) (3x+2)
Answer:
81z^3-36z = 9z(3z-2)(3z+2)
Step-by-step explanation:
(81z^3-36z)=9z(9z^2-4)
9z(9z^2-4)=9z(3z-2)(3z+2)
81z^3-36z=9z(3z-2)(3z+2)
81z^3-36z=9z(3z-2)(3z+2)
Corrine ran 4 miles in 28 minutes yesterday and
5 1/2 miles in 32 minutes
todoy Did she run
foster today or
yesterday?
Answer:
Step-by-step explanation:
First things first, you need to find out how many minutes it took Corrine to run one mile each day. To do this, you divide 4 by 4 and 28 by 4
4 ÷ 4 = number of miles
4 ÷ 4 = 1 mile
28 ÷ 4 = number of minutes for one mile
28 ÷ 4 = 7 minutes for one mile
Next, you need to divide 5.5 by 5.5 and 32 by 5.5
5.5 ÷ 5.5 = number of miles
5.5 ÷ 5.5 = 1 mile
32 ÷ 5.5 = number of minutes for one mile
32 ÷ 5.5 = 5.81818181818
So, Corrine ran one mile in 7 minutes yesterday and ran one mile in 5.81818181818 today.
All in all, Corrine ran faster today than yesterday.
Hope this helps!

m = (y2 - y1)/(x2 - x1)
m = (3 - 1)/(5 - 2)
m = 2/3 POSITIVE
Number 2
m = (y2 - y1)/(x2 - x1)
m = (-3 - 1)/(1 + 2)
m = -4/3 NEGATIVE

m = (y2 - y1)/(x2 - x1)
m = (1 - 1)/(5 - 4)
m = 0/1
m = 0 ZERO
Number 4
m = (y2 - y1)/(x2 - x1)
m = (5 - 1)/(7 - 7)
m = 4/0
m = UNDEFINED
