Terms/CoefficientsCoordinates (x, y)Solving systems of equations using substitution/eliminationStep-by-step explanation:
Step 1: Define Systems
-3x + 4y = 64
x + 4y = 32
Step 2: Rewrite Systems
x + 4y = 32
[Subtract Property of Equality] Subtract 4y on both sides: x = 32 - 4yStep 3: Redefine Systems
-3x + 4y = 64
x = 32 - 4y
Step 4: Solve for y
Substitution
Substitute in x: -3(32 - 4y) + 4y = 64Distribute -3: -96 + 12y + 4y = 64Combine like terms: 16y - 96 = 64[Addition Property of Equality] Add 96 on both sides: 16y = 160[Division Property of Equality] Divide 16 on both sides: y = 10Step 5: Solve for x
Define equation: x + 4y = 32Substitute in y: x + 4(10) = 32Multiply: x + 40 = 32[Subtraction Property of Equality] Subtract 40 on both sides: x = -8Can someone pls help? Tysm if u do! <3

What is the slope of line?
A slope of a line is the change in [tex]y[/tex] coordinate with respect to the change in [tex]x[/tex] coordinate.
Here given slope of line is
[tex]y = \frac{3}{4}x- 8[/tex]
As we know the slope of line is

Step-by-step explanation:
-3t + (-8)=25
what is t
Answer:
t = -11
Step-by-step explanation:
Solve for t:
-3 t - 8 = 25
Add 8 to both sides:
(8 - 8) - 3 t = 8 + 25
8 - 8 = 0:
-3 t = 25 + 8
25 + 8 = 33:
-3 t = 33
Divide both sides of -3 t = 33 by -3:
(-3 t)/(-3) = 33/(-3)
(-3)/(-3) = 1:
t = 33/(-3)
The gcd of 33 and -3 is 3, so 33/(-3) = (3×11)/(3 (-1)) = 3/3×11/(-1) = 11/(-1):
t = 11/(-1)
Multiply numerator and denominator of 11/(-1) by -1:
Answer: t = -11
[tex] - 3t + ( - 8) = 25[/tex]
Distribute the plus/positive in the negative. Remember that plus × minus = minus.[tex] - 3t - 8 = 25[/tex]
Solve for t-term by making t as the subject of equation.[tex] - 3t = 25 + 8 \\ - 3t = 33 \\ t = \frac{33}{ - 3} \longrightarrow \frac{ \cancel{33}}{ \cancel{ - 3} } = \frac{11}{ - 1} \\ t = - 11[/tex]
Answer Check by substituting the value of t in the equation.[tex] - 3( - 11) + ( - 8) = 25 [/tex]
Distributing or multiplying both negative, we would get positive.
[tex]33 - 8 = 25 \\ 25 = 25 \: \: \purple{ \checkmark}[/tex]
The equation is true for t = -11. Hence the answer is t = -11.
Answer[tex] \large \boxed{t = - 11}[/tex]

How many feet does a car traveling at 57 mph cover in one hour? In one minute? In one second?
Distance cover in feet in one minute and one second are 5,016 feet and 83.6 feet
Given that;
Speed of car travelling = 57 mph
Find:
Distance cover in feet in one minute
Distance cover in feet in one second
Computation:
1 mile = 5280 feetSpeed of car travelling = 57 mph
Speed of car travelling in feet = 57 × 5280
Speed of car travelling in feet = 300,960 feet per hour
Distance cover in feet in one minute = 1 × [300,960 / 60]
Distance cover in feet in one minute = 5,016 feet
Distance cover in feet in one second = 1 × [5016 / 60]
Distance cover in feet in one second = 83.6 feet

Answer:
y = 3x - 1
Step-by-step explanation:
Let's start with the two points.
y = mx + b
-19 = -6m + b

Subtract the first from the second.
24 = 8m
m = 3
5 = 2*3 + b
b = -1

Answer:
The orange region has an area of 324m²
Step-by-step explanation:
You can calculate this by finding the area of the smaller white rectangle, and subtracting it from the larger orange rectangle.
The smaller rectangle has the dimensions 8m × 5m, giving us 40m².
The larger rectangle is 13m × 28m, giving us the area 364m²
So the orange area is equal to 364m² minus 40m², or 324m²
Answer:
324[tex]cm^{2}[/tex]
Step-by-step explanation:
The are of the shaded region is equal to the area of the big rectangle minus the area of the small rectangle. So the are of the shaded region can be found in a follwoing way
The are of the shaded region = Area of the big rectangle - Area of the small recatngle
The are of the shaded region = 13 x 28 - 5 x 8
The are of the shaded region = 364 - 40
The are of the shaded region = 324[tex]cm^{2}[/tex]

There is a relationship between the number of hours a plumber works and the amount of money he earns. The plumber earns $60 for every 2 hours he works. Which statement about the relationship and the amount of money the plumber earns is true?
Practice
A
The number of hours the plumber works is the independent variable in the relationship, and he earns $270 for 9 hours of work.
B
The amount of money the plumber earns is the dependent variable in the relationship, and he earns $540 for 9 hours of work.
C
The amount of money the plumber earns is the independent variable in the relationship, and he earns $540 for 9 hours of work.
D
The number of hours the plumber works is the dependent variable in the relationship, and he earns $270 for 9 hours of work.
Answer:
Step-by-step explanation:
number of hours worked 2 = money earned $60,
so we can conclude that
the money he earned depend on the hours worked (independent variable) and that
number of hours worked 1 = money earned $30
A. True
hours worked IS the independent variable
9 hours of work = 9*$30 = $270 IS correct
B. False
money earned IS the dependent variable
9 hours of work is NOT $540
C. False
the money earned is NOT independent
for 9 hour will NOT earn $540
D.True
the number of hours IS dependent variable
the 9 hours of work IS earning $270
