Answer:
Gradient=¾
Step-by-step explanation:
Write the equation in slope-intercept form y=mx+c
3x-4y=24
-4y=24-3x
y=24/-4-3x/-4
y=-6+¾x
y=¾x-6
The gradient is therefore ¾
The y-intercept of the line occurs at(0,-6)
The x-intercept of the line occurs at(8,0)
Finding the midpoint of the two intercepts
{(x1+x2)/2,(y1+y2)/2}
M={0+8/2,(-6+0/2)}
M={8/2,-6/2}
M=(4,-3)
As you can see, the other information was not required to solve it

Aitor purchased his favorite video game for 44.95 at the mall . the sales tax rte max 7.75% what was the total cost aithor paid including sales tax
Answer:
48.43
Step-by-step explanation:
The total cost Aitor paid including sales tax will be $48.43.
What is the percentage?The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates for one hundred percent. It is symbolized by the character '%'.
The percentage is given as,
Percentage (P) = [Final value - Initial value] / Initial value x 100
The Aitor purchased his favorite video game for 44.95 at the mall. The sales tax rate is a max of 7.75%.
Let 'x' be the total cost Aitor paid including sales tax. Then the equation is given as,
7.75 = [(x - 44.95) / 44.95] x 100
0.0775 = (x - 44.95) / 44.95
3.4836 = x - 44.95
x = $48.43
The total cost Aitor paid including sales tax will be $48.43.

When the solution to the equation 5(x+4)=5x-3? A.x=20 c.there is no solution D.there are infinite solutions...
Update: the answer is there is no solution.
Answer:
The sides are not equal
Therefore, there is NO SOLUTION.
Step-by-step explanation:
Given the expression
[tex]5\left(x+4\right)=5x-3[/tex]
Expanding
[tex]5x+20=5x-3[/tex]
subtract 20 from both sides
[tex]5x+20-20=5x-3-20[/tex]
[tex]5x=5x-23[/tex]
subtract 5x from both sides
[tex]5x-5x=5x-23-5x[/tex]
[tex]0=-23[/tex]
The sides are not equal
Therefore, there is NO SOLUTION.
In a game a player wins if he rolls a 6 on a number cube if the number cube is rolled 18 times then what is an reasonable prediction for the number of unsuccsecful rollls
Answer:
the reasonable prediction for the number of unsuccessful rollls is 15 ÷ 18
Step-by-step explanation:
The computation of the number of unsuccessful rolls is as follow:
For a number cube, the probability of getting 6 would be 1 ÷ 6 and for not getting is 5 ÷ 6
Now for 18 rolls i.e. there is 3 group of 6 so the chance of not getting would be 15 ÷ 18
Hence, the reasonable prediction for the number of unsuccessful rollls is 15 ÷ 18
The same is to be considered

factorize 16x^2 - 1\144
Answer:
(4x+1/12)(4x-1/12)
Step-by-step explanation:
16x²-1/144
(4x)²-(1/12)²
(4x+1/12)(4x-1/12) (since a²-b²=(a+b)(a-b)
The factorized form of expression [tex]16x^2 - \dfrac{1}{144}[/tex] would be, [tex](4x - \dfrac{1}{12} ) (4x + \dfrac{1}{12} )[/tex]
Used the concept of a quadratic equation that states that,
An algebraic equation with the second degree of the variable is called a Quadratic equation.
And, Use the formula,
(a² - b²) = (a - b) (a + b)
Given that a quadratic equation is,
[tex]16x^2 - \dfrac{1}{144}[/tex]
The above expression is written as,
[tex]16x^2 - \dfrac{1}{144}[/tex]
[tex](4x)^2 - (\dfrac{1}{12})^2[/tex]
Apply the formula (a² - b²) = (a - b) (a + b);
[tex]= (4x - \dfrac{1}{12} ) (4x + \dfrac{1}{12} )[/tex]
Therefore, the factors are [tex]= (4x - \dfrac{1}{12} ) (4x + \dfrac{1}{12} )[/tex]

Consider the diagram. Triangles A B R and R C A share side R A. Angles B A R and A R C are right angles. Sides B R and A C are congruent. Which congruence theorem can be used to prove △ABR ≅ △RCA? HL SSS ASA SAS
Answer:
a. HL
Step-by-step explanation:
took the test on edge
The congruence theorem that can be used to prove that△ABR ≅ △RCA is; HL
We are told that; △ABR and △RCA share side RA.From the diagram attached, we can see that RA is the hypotenuse of both triangles.
From reflexive property, RA is congruent to itself. So we have the hypotenuse of both triangles congruent to each other. Now, we are told that ∠BAR and ∠ARC are right angles. This means they are equal and congruent to each other. We are also told that sides BR and AC are congruent. Now, from the image attached, we can see that BR and AC are legs of both triangles. Thus, the corresponding hypotenuse and corresponding legs of both triangles are congruent. In conclusion, the congruency theorem that can be used is HL (Hypotenuse Leg) Theorem which states that if the hypotenuse and one leg of a right triangle are congruent to the hypotenuse and one leg of another right triangle, then we can say that both triangles are congruent.Read more on HL Congruence theorem at; https://brainly.com/question/14053210

Why was this problem difficult for you?
Match each equation on the left with its simplified version from the choices on the right. Do not solve. (not all the choices will be used.) -2(3x-10)=15 __ A. -6x+2=15 ⅕(30x-10)=15 __ B. 6x-2 = 15 3(2x-10)=15 __ C. 6x+2=15 -⅕(30x-10)=15 __ D. 6x-30 = 15 E. -6x+20=15 F. -6x-20 = 15
Answer:
E. -6x + 20 = 15Step-by-step explanation:
Given the expression -2(3x-10)=15, we are to find the equivalent expression;
Open the parenthesis using the distributive law;
-2(3x-10)=15
-2(3x) -2 (-10) = 15
-6x + 20 = 15
Hence the simplified version of the expression is -6x + 20 = 15
