SOMEONE HELP ME AND EXPLAIN HOW ITS THE ANSWER PLZ!!!

Answer:

To find the Y-intercept substitute in 0 for all the x's and solve for Y

Your answer would be (0,9/2)

Steps:

Y=0^2-5(0)+9/2

0^2 -5(0)=0

Y=9/2

0 is your x place

and 9/2 is your Y intercept

Answer:

y-intercept = 9/2 or 4.5

Step-by-step explanation:

In the given quadratic equation, y = x² - 5x + 9/2, where:

a = 1, b = -5, and c = 9/2  

The y-intercept is the point at which the parabola crosses the y-axis, and occurs at point (0, c ).  It is the value of y when x = 0. To find out what I mean by this, we can substitute the value of x = 0 into the quadratic equation:

y = x² - 5x + 9/2

y = (0)² - 5(0) + 9/2

y = 0 - 0 + 9/2

y = 9/2

Therefore, the y-intercept (c) = 9/2, and has coordinates, (0, 9/2) or (0, 4.5).

Attached is a screenshot of the graph, where it shows the y-intercept.

Answer:

The number is 0.06, or 6 hundredths.

Step-by-step explanation:

If we convert 2 2/5 to a decimal, we get 2.4

Then, we can convert our percentage to a decimal by moving our digits two units down, giving us .025.

Now, we can multiply 2.4 and .025, which gives us 0.06

Answer:

-15 ÷ 3 = -5

Step-by-step explanation:

If 3 thermometers totaled -15, then they share that value equally.

Let's see

[tex]\\ \rm\longmapsto \pi/4[/tex]

[tex]\\ \rm\longmapsto \dfrac{\pi}{4}\times \dfrac{180}{\pi}[/tex]

[tex]\\ \rm\longmapsto \dfrac{180}{4}[/tex]

[tex]\\ \rm\longmapsto 45°[/tex]

The solution is: the measure in degrees (pi)/4 is 45°.

Here, we have,

given that,

we have to find  the measure in degrees (pi)/4.

now, we know that,

Measure of an Angle in Degrees = 180°        

Measure of an Angle in Radians is:

180° × (π/180°) = π = 3.14 Rad

so, we have,

π/4

= π/4 × (180°/π)

=180 /4

=45°

Hence, the measure in degrees (pi)/4 is 45°.

A) Store A

B) Store B

C) The cost is the same at both stores

C is the answer

Answer:

see explanation

Step-by-step explanation:

(1) False

A dilatation enlarges or reduces the original figure

Then the distance between consecutive vertices changes.

(2)

Assuming the centre of dilatation is at the origin then multiply the coordinates of the points by the scale factor k = 0.25 ( a reduction )

J (4, 8 ) → J' (4(0.25), 8(0.25) ) → J' (1, 2 )

K (8, 8 ) → K' (8(0.25), 8(0.25) ) → K' (2, 2 )

L (4, 2 ) → L' (4(0.25), 2(0.25) ) → L' (1, 0.5 )

Answer:

B is the answer hope you get it right

Step-by-step explanation:

9. a)

2•(-2) = 2 - 6

-4 = -4

-2 -2 = -2•2

-4 = -4

Yes, the ordered pair is the solution

9. b)

-1 = 3•(-2) +5

-1 = -6 +5

-1 = -1

3•(-2) +(-1) = -2

-6 -1 = -2

-7 ≠ -2

No, the ordered pair is not the solution

10. (-1, -1) and (3, -1)

11.

y = 6 +x

Now substitute it in the first equation:

3•(6 +x) = 5x

18 + 3x = 5x

18 = 2x

x = 18/2

x = 9

Now, substitute x = 9 in the second equation:

y -9 = 6

y = 6 +9

y = 15

Answer:A 3%

Step-by-step explanation:

Answer:

[tex]2x + 7 = 3x - 7 \\ 3x - 2x = 7 + 7 = 14 \\ x = 14 \\ 2x + 7 + 12y + 1 = 180 \\ 12y + 36 = 180 \\ 12y = 180 - 36 = 144 \\ y = 144 \div 12 = 12[/tex]

Answer:

40i²-5i+45

Step-by-step explanation:

Answer:

y = -5/2x + -4 (or) y = -5/2x - 4

Step-by-step explanation:

Your slope is -5/2, so all you have to do is take the point (-2, 1) and use the slope to find a second point of (0, -4) which is coincidentally the y-intercept. Then you just plug the data into the equation y = mx+b. You do that and you get the answer of y = -5/2x+-4

Explanation:

Anything is categorized by how it matches with the definition of the category.

A composite number is a product of primes. A prime number is divisible only by itself and 1.

If a number has more than one prime factor (even if that is just multiple instances of the same prime factor), it goes into the composite number category. If its only prime factor is itself, it goes into the prime number category.

Saya yakin jawabannya adalah -26 karena ketika Anda melakukan perkalian terlebih dahulu, kemudian lakukan pecahan 33 1/2 dan setelah itu Anda akan menambahkan 2 dan pengurangan 5,5 yang semuanya akan sama dengan -26. semoga saya benar dan ini membantu. (:
