Answer:
Step-by-step explanation:
yes....the pair of linear equations has unique solution.....
2x + 3y - 7 = 0 ...... (i)
3x + 2y + 10 = 0 ....... (ii)
on comparing the equation i nd ii with a1x + b1y + c1 = 0
nd a2x + b2y + c2 = 0 reslectively......
a1 = 2 ; b1 = 3 ; c1 = -7
a2 = 3 ; b2 = 2 ; c2 = 10
here....its clear that......
a1 / a2 is not equal to b1 / b2
Therefore the given pair of linear equation have a unique solution........

Answer : -3 And -9
Explanation : -9 * -9 = 81 So -9 Is True And -9 + -9 = -18
And -3 * -27 = 81 And -3 + -3 + -3 + -3 + -3 + -3 = -18

The number of loaves of bread purchased and the total cost of the bread in dollars can be modeled by the equation c = 3.5b. Which table of values matches the equation and includes only viable solutions?
Answer:
Loaves of bread: b can't be a negative value, then the first table doesn't include viable solutions.
The number of loaves of bread must be a whole number, then the second table doesn't include viable solutions.
c=3.5b
if b=0→c=3.5(0)→c=0
If b=3→c=3.5(3)→c=10.5
If b=6→c=3.5(6)→c=21
If b=9→c=3.5(9)→c=31.5
The third table includes viable solutions
LABOR Ed earned $112 for 8 hours of
work. At this rate, how much will he
earn for 40 hours of work?
Answer:
Ed would earn $4480
Step-by-step explanation:
you could solve this by ratios
make x = the amount of money he would earn if he worked 40 hrs
step 1: write the ratio
112/8 = x /40
step 2: cross multiply
8x = 4480
step 3: isolate x by dividing
8x/8 = 4480/8
answer: x = 560

Step-by-step explanation:
1. when x is 0
y will be
4x+2y=10
4(0)+2y=10
0+2y=10
collect like terms
2y=10-0
2y=10
divide both sides by 2
2y/2=10/2
y=5
so when x =0 y will equal to 5
2. when x is 1
y will be
4x+2y=10
4(1)+2y=10
4+2y=10
collect like terms
2y=10-4
2y=6
divide both sides by two
2y/2=6/2
y=3
so when x is 1, y is 3
3. when x is 2
4x+2y=10
4(2)+2y=10
8+2y=10
(CLT) 2y=10-8
2y =2
y= 1
Answer:
( x ,y) = ( 0, 5), ( 1, 3), ( 2, 1 ), ( 3, -1)
given equation: 4x + 2y = 10
rewrite it as:
2y = 10 - 4xy = 5 - 2xsolve:
when x = 0
y = 5 - 2(0)
y = 5
when x = 1
y = 5 - 2(1)
y = 3
when x = 2
y = 5 - 2(2)
y = 1
when x = 3
y = 5 - 2(3)
y = -1
What is an equation of the line that passes through the point (-2,-3) and is parallel to the line 4x-y=1
Answer: y = 4x + 5
Step-by-step explanation:
Rearranging 4x-y = 1 we get y = 4x-1 as the equation of the line.
Since the new line is parallel to y=4x-1, that means the slopes are equal. Therefore, the slope of the line is 4.
So, the equation of the line is y = 4x+b
To figure out b, we can plug in the point (-2,-3) into the equation.
So -3 = -2*4 + b
-3 = -8 + b
And we get b = 5.
Therefore, the equation of the line is y = 4x + 5
Answer:
y = 4x + 5
Step-by-step explanation:
First, we need to find the slope of the given equation: 4x - y = 1
Subtract 4x from both sides
4x - y = 1
- 4x - 4x
-y = 1 - 4x
Divide both sides by -1 to make the y variable positive
-y/-1 = (1 - 4x)/-1
y = -1 + 4x
This means the slope of this equation is 4
Our parallel equation will be y = 4x + b
Plug in the given coordinates
-3 = 4(-2) + b
-3 = -8 + b
Add 8 to both sides
-3 = -8 + b
+ 8 + 8
b = 5
Plug in the new b into the original parallel equation
y = 4x + 5
Nicole and Elena wanted to know if listening to music at a louder volume negatively impacts test performance. To investigate, they recruited 30 volunteers and randomly assigned 10 volunteers to listen to music at 30 decibels, 10 volunteers to listen to music at 60 decibels, and 10 volunteers to listen to music at 90 decibels. While listening to the music, each student took a 10-question math test. Given is computer output from a least-squares regression analysis using = volume and = number correct.

f(x) = 2x - 3 and g(x) = x - 1.
Find f((g(x)) - g(f(2))
Answer:
(f + g)(x) = I2x + 1I + 1 ⇒ C
Step-by-step explanation:
∵ f(x) = I2x + 1I + 3
∵ g(x) = -2
→ We need to find (f + g)(x), which means add the two functions
∵ (f + g)(x) = f(x) + g(x)
→ Substitute the right side of each function on the right side
∴ (f + g)(x) = I2x + 1l + 3 + (-2)
→ Remember (+)(-) = (-)
∴ (f + g)(x) = I2x + 1I + 3 - 2
→ Add the like terms in the right side
∵ (f + g)(x) = I2x + 1I + (3 - 2)
∴ (f + g)(x) = I2x + 1I + 1
