find the slope of the line created from the points on the table. A. 1/7 B. -7 C. 2/3 D. - 3
Table:
x y
2 14
3 7
4 0
5 -7
Answer:
B. -7
Step-by-step explanation:
Formula to find slope is (y2-y1) / (x2-x1)
Here we have 4 points to choose from, but we only need 2. I will use the first 2 points.
The y2 is 7, the y1 is 14, the x2 is 3, the x1 is 2.
Substitute these numbers into the formula.
(7-14) / (3-2)
^ This is basically -7/1, or -7.

PLS HELP WILL GIVE BRAINLIEST
Answer:
Step-by-step explanation:
For number 1.
If x = -2.
y = 4x + 3 = 4(-2) + 3 = -8 + 3 = -5
If x = 3
y = 4x + 3 = 4(3) + 3 = 12 + 3 = 15
If x = -4
y = 4x + 3 = 4(-4) + 3 = -16 + 3 = -13
If x = -5
y = 4x + 3 = 4(-5) + 3 = -20 + 3 = -17
If x = 5
y = 4(x) + 3 = 4(5) + 3 = 20 + 3 = 23
For number 2.
If x = -2
[tex]y = x^{2} + 4 + 2x = (-2)^{2} + 4 + 2(-2) = 4 + 4 - 4 = 4[/tex]
If x = 3
[tex]y = x^{2} + 4 + 2x = (3)^{2} + 4 + 2(3) = 9 + 4 + 6 = 19[/tex]
If x = -3
[tex]y = x^{2} + 4 + 2x = (-3)^{2} + 4 + 2(-3) = 9 + 4 - 6 = 7[/tex]
If x = 4
[tex]y = x^{2} + 4 + 2x = (4)^{2} + 4 + 2(4) = 16 + 4 + 8 = 28[/tex]
If x = -4
[tex]y = x^{2} + 4 + 2x = (-4)^{2} + 4 + 2(-4) = 16 + 4 -8 = 12[/tex]

Ben deposited $650 from his pressure washing business into a savings account. The simple interest rate paid by the bank is 3.5%. If Ben makes no deposits or withdrawals, how much interest will he earn in 4 years?
9514 1404 393
Answer:
$91
Step-by-step explanation:
The amount of interest earned is given by the formula ...
I = Prt
where P is the invested amount at rate r for t years.
Filling in the given values, we find the interest to be ...
I = $650·0.035·4 = $91
Ben will earn $91 interest in 4 years.

What does the formula of an ionic compound tell you?
A map is drawn using a scale of 1cm/80 mi
Two cities are 280 miles apart
How far apart are the cities on the map?
Answer:
280/80 = 28/8 = 7/2 = 3.5 cm
Step-by-step explanation:
the ratio is 1cm/80mi = a cm/280mi
so you get 280cm * mi = 80mi*a cm
so a = 280/80 = 3.5

Answer:
Quantité totale d'essence consommée: 167 litres (arrondie à l'unité pres)
Nombre de jours du voyage: 12 jours (je pense! Je ne comprends pas "jours sants" ? Suivants? )
Distance parcourue pour aller à Pittsburgh: 1269.8 km
coût total de l'essence: $ 204.11
Coût moyen de l'essence consommée par jour (arrondi au centieme pres): $17.01
Distance parcourue par jour pour le retour: 613.5 km
Distance totale parcourue durant les vacances: 2496.8 km
Step-by-step explanation:
Jour 1 Montreal à Parc Sandbanks
2,3,4,5 Parc Provincal Sandbanks
6,7,8,9,10 Pittsburgh
11,12 Pittsburgh à Quebec
Distance: ajouter les numéros jours par jour.
Essence consommée: 6.7 litres pre 100, donc diviser la distance totale par 100 puis multiplier par litres par km
2496.8/100 = 24.968 × 6.7 = 167.2856 et arrondir le total: 167.3
Coût total de l'essence: Il faut multiplier le total consommée par la coût par litre, $1.22 167.3×1.22 = $204.11
Coût moyen de l'essence consommée par jour: $204.11 ÷ 12 jours = $17.01/jour
Distance parcourue par jour pour le retour: 1227km/2days = 613.5 km/jour
Distance totale parcourue durant les vacances: Ajoutez les distances journalières parcourues à Pittsburgh à la distance de retour à Quebec.
1269.8 + 1227 = 2469.8 km

Plz I need help
Answer:
<ABC = 51°
Step-by-step explanation:
Given
<A = 2x -15°
<B = x - 5°
< C = 148°
Now
<A + <B = < C ( Exterior angle of a triangle is equal to the sum of two opposite interior angles)
2x -15° + x - 5° = 148°
3x - 20° = 148°
3x = 148° +20°
3x = 168°
x = 168° / 3
X = 56°
Now for Angle B
= 56° - 5°
= 51°

A triangle on a coordinate plane is translated according to the rule T-3,56%, y). Which is another way to write this
rule?
(x, y) - (x-3, y + 5)
(x, y) - (x-3, y-5)
(x, y) - (x + 3. y-5)
(x, y) - (x + 3, y + 5)
Given:
Consider the rule of translation of a triangle is [tex]T_{(-3,5)}(x,y)[/tex].
To find:
The another way to write this rule.
Solution:
We have, the rule of translation [tex]T_{(-3,5)}(x,y)[/tex].
We know that [tex]T_{(a,b)}(x,y)[/tex] is defined as
[tex](x,y)\to (x+a,y+b)[/tex]
So, [tex]T_{(-3,5)}(x,y)[/tex] can be defined as
[tex](x,y)\to (x+(-3),y+(5))[/tex]
[tex](x,y)\to (x-3,y+5)[/tex]
It means, the triangle is translated 3 units left and 5 units up.
Therefore, the correct option is A.
Answer:
A

What is the vertex of the function defined as
g(x) = f(x – 5) + 3?
Answer:
f=gx−3/x−5
Step-by-step explanation:
Step 1: Flip the equation.
fx−5f+3=gx
Step 2: Add -3 to both sides.
fx−5f+3+−3=gx+−3
fx−5f=gx−3
Step 3: Factor out variable f.
f(x−5)=gx−3
Step 4: Divide both sides by x-5.
f(x−5)/x−5=gx−3/x−5
Plot the points (-3, 4)(−3,4)left parenthesis, minus, 3, comma, 4, right parenthesis and (4, 4)(4,4)left parenthesis, 4, comma, 4, right parenthesis on the coordinate plane below
Answer:
The image shows the points on a coordinate axis.
Step-by-step explanation:
The first point is [tex](-3,4)[/tex].
This means that the point on the [tex]x[/tex] axis is [tex]-3[/tex] and [tex]y[/tex] axis is [tex]4[/tex]. The point is in the second quadrant.
The second point is [tex](4,4)[/tex].
This means that the point on the [tex]x[/tex] axis is [tex]4[/tex] and [tex]y[/tex] axis is [tex]4[/tex]. The point is in the first quadrant.
The image shows the points on a coordinate axis.

у+ 4 = -4(х+2) what is this in standard form?
Answer:
4x + y = -12
Step-by-step explanation:
Standard form is Ax + By = C
First, distribute the -4:
у + 4 = -4(х + 2)
y + 4 = -4x - 8
Subtract 4 from both sides:
y = -4x - 12
Add 4x to both sides:
4x + y = -12
So, the standard form equation is 4x + y = -12

You earn $28 for washing 4 cars. How much do you earn for washing 3 cars?
Answer:
21 dollars
Step-by-step explanation:
Answer:
$21
Step-by-step explanation:
Make the original statement into a ratio.
$28/4
Simplify the fraction above.
$28/4 = 7
So, you earn $7 per car you wash.
As a result, you multiply $7 by the number of cars the question is asking you for. In this case it is 3 cars.
So, you multiply 7 x 3
7 x 3 = 21
Therefore, you will earn $21 for washing 3 cars.
