Answer:
[tex]y - 7x = 21[/tex]
Step-by-step explanation:
Given
[tex]y = (x + 4)7 - 7[/tex]
Required
Convert to standard form
[tex]y = (x + 4)7 - 7[/tex]
Start by opening the bracket
[tex]y = x*7 + 4*7 - 7[/tex]
[tex]y = 7x + 4*7 - 7[/tex]
[tex]y = 7x + 28 - 7[/tex]
[tex]y = 7x + 21[/tex]
Subtract 7x from both sides
[tex]y - 7x = 7x - 7x + 21[/tex]
[tex]y - 7x = 21[/tex]
Hence:
The standard form is: [tex]y - 7x = 21[/tex]
Write and solve the algebraic inequality.
The product of –3 and a number is at least -24.
A. -3x -24; x S 8
B. -3x -24; x 8
C. -3x <-24; x>-8
D. -3x >-24; x>-8
Step-by-step explanation:
Lets convert each sentence into an algebric inequality.
Product of -3 and a number (let it be x) :-[tex] = > - 3 \times x = - 3x[/tex]
-3x is atleast -24[tex] = > - 3x \geqslant - 24[/tex]
Lets solve the inequality.
Now , divide -3 on both the sides -
[tex] = > \frac{ - 3x}{-3} \geqslant \frac{ - 24}{ - 3} [/tex]
[tex] = > x \geqslant 8[/tex]

x - 3y = -12
2x + 3y = 3
Answer:
Step-by-step explanation:
to solve this system of equations we will add them
x-3y=-12
2x+3y=3 now +3y-3y=0
3x=-12+3
3x=-9
x=-3
plug in the first equation
-3-3y=-12
-3y=-12+3
-3y=-9
y=3

jan has a 12-ounce milkshake.Four ounces in the milkshake are vanilla,and the rest is chocolate.What are two equivalent fractions that represent the fraction of the milkshake that is vanilla
Answer:
In this item, we are given that out of 12 ounces of ingredients comprising the milkshake, there are 4 ounces vanilla. Expressing this into fraction will give us an answer of 4/12. This fraction can be one of the answers. Since we are asked for two fractions, we can simplify 4/12 such that we get an equivalent fraction that is equal to 2/6. Hence, the answers to this question are 4/12 and 2/6.

Answer:
I solved it for u!
Hope it helps
Step-by-step explanation:
Another way, it an isosceles triangle so the base will be same, so angle 3 and angle 1 will be same after u find angle 3, then angle 1 will be equal to it
So here angle 3 = 64°
So angle 1= 64°
Taylor walks 7 miles in 2 hours. At what unite rate dose Taylor walk
Answer:
C
Step-by-step explanation:
Unit rate means that the denominator of the units has to be 1: units have to be miles/1 hour
Thus divide miles by hours to get the unit rate. The answer would then be 7/2 miles/1 hour

Use the figure below to answer the following questions.
What is mZ2?
Answer:
angle2 = 50º
Step-by-step explanation:
Angle 1 is 60º because of the vertical opposite angle rule
There are 180º in a Triangle. So...
70º + 60º + angle2 = 180º
130º + angle2 = 180º
angle2 = 50º
Given a triangle ABC has angles of A = 30 and B = 70, what is the smallest side?
Answer:
A=30 is the smallest side
Step-by-step explanation:
A+B+C= 180
30+70+C=180
100+C=180
C=180-100
C=80
Therefore, A=30 is the smallest side of the triangle...
A triangle has sides with lengths of 3 yards, 4 yards, and 5 yards. Is it a right triangle?

Write a linear function f with f (5) = -1 and f(0) = -5.
f(x)=____
Answer:
We conclude that the equation of a linear function with f (5) = -1 and f(0) = -5 will be:
f(x) = 4/5x - 5Step-by-step explanation:
Given
f(5) = -1f(0) = -5f(5) = -1 means at x = 5, y = -1
Hence, the point (5, -1) lies on the line function.
f(0) = -5 means at x = 0, y = -5
Hence, the point (0, -5) lies on the line function.
Thus, the two points on the linear line function graph are:
(5, -1)(0, -5)Finding the slope between the points (5, -1) and (0, -5)
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(5,\:-1\right),\:\left(x_2,\:y_2\right)=\left(0,\:-5\right)[/tex]
[tex]m=\frac{-5-\left(-1\right)}{0-5}[/tex]
[tex]m=\frac{4}{5}[/tex]
The slope-intercept form of the linear line function
[tex]y = mx+b[/tex]
where m is the slope and b is the y-intercept
We have already determined the slope which is: m = 4/5
We know the y-intercept can be determined by setting x = 0 and solving for y.
Thus, the point (0, -5) represents the y-intercept b = -5.
Now, substituting m = 4/5 and b = -5 in the slope-intercept form
[tex]y = mx+b[/tex]
y = 4/5x + (-5)
y = 4/5x - 5
Therefore, we conclude that the equation of a linear function with f (5) = -1 and f(0) = -5 will be:
f(x) = 4/5x - 5The cost of renting a canoe to use on River Y costs $. The cost of renting a canoe to use on River Z costs $ per hour plus a $ deposit.

What is the area of the football field in the scale drawing? Assume that the field is shaped like a rectangle.
Answer:
i mean might as well get free points now that its 2 weeks old
Step-by-step explanation:
Answer:
Pythagorean Theorem: the diagonal of the football field is the hypotenuse. Let´s say the diagonal is C and the two other sides are A and B.
Width = A
Length = B
Diagonal = C
so: a2+b2=c
2502+1002=c2
2500+10000=c2
12500=c2
c=√12500
c=111.80 yards

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
