Answer:
False
Step-by-step explanation:
Well we can try this by putting it into the equation
4(-1)+3(5)=1
4*-1=-4
3*5=15
-4+15=1 This statement is false, -4+15 actually equals 11
(7^3)^-5

Please help! The question and answer choices are attached.
Answer:
A
Step-by-step explanation:
We want to find the equation of the line in slope-intercept form.
From the graph, we are given the two points (-5, 1) and (0, -3).
We can find the slope between them. The slope formula is given by:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]
We will let (-5, 1) be (x₁, y₁) and (0, -3) be (x₂, y₂). Substitute:
[tex]\displaystyle m=\frac{(-3)-(1)}{(0)-(-5)}[/tex]
And evaluate:
[tex]\displaystyle m=\frac{-4}{5}=-\frac{4}{5}[/tex]
Next, notice that the point (0, -3) is already the y-intercept, so we do not need to find it.
Slope-intercept form is given by:
[tex]\displaystyle y=mx+b[/tex]
Therefore, our equation is:
[tex]\displaystyle y=-\frac{4}{5}x-3[/tex]
Our answer is A.

ps pls tell me if it was correct :)
please i need help with this asap!!! I will give brainliest!!! please and thank you!!
Answer:
The y-intercept is 2 and the slope is 1/2. So the equation is y = 1/2x + 2
Step-by-step explanation:
The y-intercept is where the line starts on the y-axis. For the slope to the next point on the line you have to move 2 units to the right and 1 unit up. When writing the slope as a fraction, you always put how far you move up or down above how far you move to the right or left.

How can you determine the number of solutions of a system of linear equations by inspecting its equations?
Step-by-step explanation:
To find - How can you determine the number of solutions of a system
of linear equations by inspecting its equations?
Proof -
There exists three types of solution for a system of linear equations.
1. No solution.
2. Unique solution.
3. Infinite many solutions.
Now,
Let the 2 linear equations are as follows :
y = ax + b
y = cx + d
1. For no solution -
a = c and b ≠d
For example-
y = -2x + 5
y = -2x - 1
Subtract first equation from second , we get
y - y = -2x - 1 - ( -2x + 5)
⇒0 = -2x - 1 + 2x - 5
⇒0 = -6
Not possible
So, There exist no solution.
2. For unique solution -
a ≠ c and b , d can be any value
For example -
If b and d are same ,
y = 2x - 4
y = -3x - 4
Subtract equation 1st from 2nd , we get
y - y = -3x - 4 - ( 2x - 4)
⇒0 = -3x - 4 - 2x + 4
⇒0 = -5x
⇒x = 0
⇒y = 2(0) - 4 = -4
∴ we get
x = 0, y = -4
If b and d are different
y = 2x - 4
y = -3x + 5
Subtract equation 1st from second
y - y = -3x + 5 - 2x + 4
⇒0 = -5x + 9
⇒-5x = -9
⇒x = [tex]\frac{9}{5}[/tex]
⇒y =2([tex]\frac{9}{5}[/tex]) - 4 = [tex]\frac{18}{5} - 4 = \frac{18 - 20}{5} = -\frac{2}{5}[/tex]
∴ we get
x = [tex]\frac{9}{5}[/tex] , y = [tex]-\frac{2}{5}[/tex]
3. Infinitely many solution -
a = c and b = d
For example -
y = -4x + 1
y = -4x + 1
Subtract equation first from equation second
y - y = -4x + 1 - ( -4x + 1)
⇒0 = -4x + 1 + 4x - 1
⇒0 = 0
Satisfied
So, Infinite many solution possible.

Write an expression equivalent to 6 - 4(3 - 6m) + 12m that is the product of two factors. Show your work.
Answer: 6(6m - 1)
Step-by-step explanation:
6 - 4(3 - 6m) + 12m
= 6 -12 + 24m + 12m
= 36m - 6
= 6(6m - 1)

Answer:
d
Step-by-step explanation:
The answer is C.
Step-by-step explanation:
First, you have to find the angle of ACB using Sine Rule, sinθ = opposite/hypotenuse :
Given that line AB is parallel to line CD so ∠C = 90°. Next, you have to find the angle of ACD :
Lastly, you can find the length of CD using Cosine rule, cosθ = adjacent/hypotenuse :

Alyson earned $40 in commission from her sales. How much did she sell if her commission rate is 15%?
Answer:
$266.67 (Verified) ✅Step-by-step explanation:
Let the merchandise she sold = x
Her commission is 15% of that, so 15% of x or 0.15x
We know her commission was $40, so 0.15x = $40
0.15x = $40
Divide by 0.15
x = $266.67
We can check our answer by substituting $266.67 back into the equation.
0.15(266.67) = 40
40 = 40 ✅
Alyson sold $266.67 worth of merchandise.
