Answer:

-2

Step-by-step explanation:

8(-a)^2+24*-a=80

or,8a^2-24a=80

or,8a^2-24a-80=0

or,8(a^2-3a-10)=0

or,a^2-3a-10=0

or,a^2-(5-2)a-10=0

or,a^2-5a+2a-10=0

or,a(a-5)+2(a-5)=0

or,(a-5)(a+2)=0

either,

a-5=0

•°•a=5

or,

a+2=0

•°•a=-2(negative integer)

The value of the unknown integer is -2.

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given data eight times the square of a negative integer plus 24 times the negative integer equals 80 in the form of the mathematical expression will be written as:-

8(-a)²+24-a=80

8a²-24a=80

8a²-24a-80=0

8(a²-3a-10)=0

a²-3a-10=0

a²-(5-2)a-10=0

a²-5a+2a-10=0

a(a-5)+2(a-5)=0

(a-5)(a+2)=0

a-5=0

a=5 or, a+2=0 a=-2

Therefore, the value of the unknown integer is -2.

Answer:

[tex]\frac{4}{3}[/tex]

Step-by-step explanation:

The average rate of change can be found by using the following formula

[tex]\frac{f(x_{2}) - f(x_{1}) }{x_{2} - x_{1}}[/tex]

Since the interval goes from -7 to 2, we should find the y-values that correspond to x=-7 and x=2.

By inspection of the graph, we can clearly see that when x is -7, y is -7 as well and when x is 2, y is 5.

Now that we know this, we can simply plug these values into the formula!

[tex]\frac{f(2) - f(-7) }{2 - (-7)} = \frac{5 - (-7)}{2 - (-7)} = \frac{5 +7}{2+7} = \frac{12}{9} = \frac{4}{3}[/tex]

Good luck!

Answer:

BC 4 in

Step-by-step explanation:

The steps for construction;

From calculation, length BC can be found by the formula;

[tex]BC=\sqrt{a^2+b^2-2*a*b*cosA}[/tex]------where a=b=4 in , cos A = cos 60°

[tex]BC=\sqrt{4^2+4^2-2*4*4*cos60}[/tex]

BC = 4 in

Answer:

bc = 4

Step-by-step explanation:

Answer:

x=2

Step-by-step explanation:

4 (x + 6) - 3x = 26

solve the parenthesis

4x + 24 - 3x = 26

subtract 24 from both sides to get x by itself

4x - 3x = 2

solve

x = 2

Complete question :

Lilian purchased a violin form smash music stores. It regularly sold for $670, but wa son slaw for 10% off. She also had to pay 8% sales tax. She bought it on the installment plan and paid 15% of the total cost with tax as a down payment. Her payments were $58 per month for one year. What is her sales tax?

Answer:

$48.24

Step-by-step explanation:

Given that:

Sales price = 670

Discount = 10% off

Sales tax = 8%

Discounted price = (1 - 0.1) * 670

Discounted price = 0.9 * 670 = $603

Hence, purchase price = $603

Hence, sales tax = 8% of purchase price

8% of $603

0.08 * 603 = $48.24

Complete question :

Tom will rent a car for the weekend. He can choose one of two plans. The first plan has an initial fee of $57.98 and costs an additional $0.14 per mile driven. The second plan has an initial fee of $53.98 and costs an additional $0.16 per mile driven. How many miles would Tom need to drive for the two plans to cost the same?

Answer:

200 miles

Step-by-step explanation:

Let miles driven = x

First option :

57.98 + 0.14x

Second option :

53.98 + 0.16x

First option = second option

57.98 + 0.14 = 53.98 + 0.16x

57.98 - 53.98 = 0.16x - 0.14x

4 = 0.02x

x = 200

200 miles

Answer:

32 - 1

Step-by-step explanation:

Answer:

Math seems difficult because it takes time and energy. Many people don't experience sufficient time to "get" math lessons, and they fall behind as the teacher moves on. Many move on to study more complex concepts with a shaky foundation. We often end up with a weak structure that is doomed to collapse at some point.

Math is hard because it is a non-intuitive, non-natural activity. Math don't happen by chance only, it only happens with deliberate, focused work. For this you expend a lot of energy and cause a lot of mental strain, you put yourself on an uncomfortable condition for hours, days, sometimes weeks to solve a problem.

But some people love math, like me, because they study math more than others. If you study more and learn more about math, then you’ll start to feel more comfortable because you’ll be ahead of the class when your teacher teaches you something.

The most important thing is to keep trying and never give up.

Answer:

ab

Step-by-step explanation:

Answer:

y=4x+3

Step-by-step explanation:

The slope is positive 4 and the y intercept is 3

Answer:

y = 4x + 3

Step-by-step explanation:

y = mx + b

m is the slope and b is the y-intercept

The slope is how much units it goes up/down while how much units it goes left/right from one point to the other. So two points we'll use for reference is (-1, -1) and (0, 3). You want to make sure the points u choose are whole numbers cause they're easier to tell. So the distance between those 2 points if it goes to the right once and goes up 4 units. Left/right is x and up/down is y, y/x is how u write the slope. So it's 4/1 which is just 4

The y-intercept is just where the line intercepts on the y-axis. The line goes through the point 3 on the y-axis, so it's 3

Input the numbers in the equation and it's y = 4x + 3
