Answer:
Check the explanation.
Step-by-step explanation:
As the graph of a linear function f passes through the point (-2,-10) and has a slope of 5/2.
As the slop-intercept form is given by:
[tex]y = mx+b[/tex]
where m is the slope and b is the y-intercept.
substituting the values (-2, -10) and m = 5/2 in the slop-intercept form to determine y-intercept.
[tex]y = mx+b[/tex]
[tex]-10=\frac{5}{2}\left(-2\right)+b[/tex]
[tex]-\frac{5}{2}\cdot \:2+b=-10[/tex]
[tex]-5+b=-10[/tex]
[tex]-5+b+5=-10+5[/tex]
[tex]b=-5[/tex]
And the equation of the line in the slope-intercept form will be:
[tex]y = mx+b[/tex]
putting b = -5 and slope = m = 5/2
[tex]y = mx+b[/tex]
[tex]y=\frac{5}{2}x+\left(-5\right)[/tex]
[tex]y=\frac{5}{2}x-5[/tex]
Determining the zero of function.
As we know that the real zero of a function is the x‐intercept(s) of the graph of the function.
so let us determine the value of x (zero of function) by setting y = 0.
[tex]0=\frac{5}{2}x-5[/tex]
[tex]\frac{5}{2}x-5=0[/tex]
[tex]\frac{5}{2}x=5[/tex]
[tex]5x=10[/tex]
[tex]x=2[/tex]
Therefore, the zeros of the function will be:
x = 2Janet has 17 quarters and $13 in bills. How much total money does she have? *
Answer: 17.25
Step-by-step explanation:
17 x 25= 425. Obviously we can’t leave it like that. So 100 cents is one dollor right?
That means there are four dollars. Made up just by the quarters alone. Now we have to add the 13 dollars 13+4 =17.Now add back the 25 cents to make $17.25
Janet has $17.25

Write and evaluate the expression.Check all that apply. Write the expression as 11 +t2 -6 Write the expression as 11 +2t -6 Write the expression as 11 +StartFraction t Over 2 EndFraction -6 The value when t = 5 is 16. The value when t = 5 is 30. The value when t = 5 is 7.5.
Answer:
7.5Step-by-step explanation:
Given the expression 11 + t/2 - 6, we are the find the output value when t = 5. To do that, we will simply substitute t = 5 into the given expression as shown;
f(t) = 11 + t/2 - 6
f(5) = 11 + 5/2 - 6
f(5) = 11 + 2.5 - 6
f(5) = 13.5 - 6
f(5) = 7.5
Hence the value of the function when t = 5 is 7.5

Answer:
correct
Step-by-step explanation:
he is correct because the transformation is a translation and under the translation the image and preimage are congruent.
the measure of the sides are preserved, and the peasure of the angles are preserved so if all the corsponding sides and angles are congruent the hexagons are congruent too

Answer:
y = 50x+25
f(x) = 50x+25
Step-by-step explanation:
Using the slope intercept form of the equation, y = mx+b
where x is the amount per day and b is the flat fee
2 days
125 = 2x+b
5 days
275 = 5x+b
Subtract
275 = 4x+b
125 = 2x+b
---------------------
150 = 3x
Divide by 3
150/3 = 3x/3
50 =x
The cost per day is 50 dollars
y = 50x +b
Using the data for 2 days
125 = 50*2 +b
125 = 100 +b
125-100 = b
b = 25
The equation is y = 50x+25
f(x) = 50x+25
To graph, The x axis is number of days and the y axis is total cost
The number of days starts with 0, which is the y intercept
Let x = 0, y =25
Using the slope, we go 50 up and 1 to the right ( 50 dollars per day)
The next point plotted ins ( 1,50)
Draw a straight line
Answer:
y = 50x+25
f(x) = 50x+25

Taira used 3/4 of her flour to make 2/5 of a batch of bannock. How much of her flour would she need to make a whole batch?
Answer:
15/8 or 1.875
Step-by-step explanation:
Let x represent a whole batch of bannock. Taira used 3/4 of her flour to make 2/5 of a whole batch so we can write the equation like this.
3/4=2/5x
Isolate x by multiplying the left side by the reciprocal of 2/5.
15/8=x

OMG PLEASE HELP!!! NEED WITHIN FEW HOURS!! The diagram shows three circles with radii r=10 cm. The centers also form the vertices of an equilateral triangle.
Answer: 16.205 cm²
It takes some time, but it's not impossible!
Step-by-step explanation:
Find the area of the triangle, then subtract the area of the three sectors.
The three sectors are each 60° so they add to 180° which is equivalent to half the area of one circle.
The area of the triangle is one half base times height. To find the height of the triangle, use the Pythagorean Theorem to get the length of the perpendicular bisector.
a² + b² = c² .
C is the side length, 20cm. (the length of two radii) B is half the side length 10cm. A is the "altitude" or height we need to find.
a² + 10² = 20²
a² + 100 = 400 . a² = 400-100
a² = 300
a = √300 a ≈ 17.3205
Area of triangle: A= bh/2
A = (20 × 173.205)/2
Triangle Total Area ≈ 173.205
To the area of the circle, use the equation A = πr²
A = 3.14 × 10²
A = 3.14 × 100
Circle Total Area = 314 cm².
You could take 1/6 of that, and then multiply by 3, or just take half
Area of sectors= 157 cm²
Triangle Area - Sectors Area = Blue shape Area
173.205 - 157 ≈ 16.205 cm²

A jacket was on sale for 20% off its original price of $60. Now, it is on sale for an additional 10% off its previous sale price. Determine whether each statement is true or false.
Step-by-step explanation:
The question is incomplete, here is the complete one
A jacket was on sale for 20% off its original price of $60. Now, it is on sale for an additional 10% off its previous sale price. Determine whether each statement is true or false. The jacket is now 40% off its original price. True or false The jacket now costs $48.00. True or false The jacket is now 72% of its original price. True or false The jacket now costs $43.20. True or false
Step one:
given
original price= $60
discount =20% of 60
discount = 20/100*60
discount = 0.2*60
discount = $12
selling price= 60-12= $48
Added price= 10% off $48
Added price= 10/100 *48
Added price= 0.1 *48
Added price= $4.8
new price= 4.8-48=$43.2
the new price of the jacket is $43.2
1. The jacket is now 40% off its original price
40/100*60=$24-----False
2. The jacket now costs $48.00-----False
3. The jacket is now 72% of its original price= 72/100*60=$43.2----True
4. The jacket now costs $43.20------True

Which equation is equivalent to the equation 3x - 12 = 24?
A) 15x - 60 = 120
B) 3x = 12
C) 3x = 36
D) x - 4 = 8
E) 12x - 12 = 24
Answer:
C
Step-by-step explanation:
To simplify the equation, all you need to do is add 12 to both sides to cancel out the -12.
The equations that are equivalent to the equation 3x - 12 = 24 are
3x = 36
x - 4 = 8
15x - 60 = 120
Options A, C, and D are correct.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example: x + 2 = 7 is an equation.
We have,
3x - 12 = 24 ____(1)
From (1)
Adding 12 on both sides.
3x = 24 + 12
3x = 36 ____(2)
From (1)
Dividing 3 into both sides.
x - 4 = 8 ____(3)
From (1)
Multiplying 5 into both sides.
5 (3x - 12) = 5 x 24
15x - 60 = 120 ____(4)
From (2), (3), and (4) we see that,
3x = 36
x - 4 = 8
15x - 60 = 120
Thus,
The equations that are equivalent to the equation 3x - 12 = 24 are
3x = 36
x - 4 = 8
15x - 60 = 120
