Solve the equation 17=5k-3
Answer:
k = 4
Step-by-step explanation:
17 = 5k - 3
+3. +3
20/5 = 5k/5
4 = k
k = 4
Answer: k = 4
17=5k-3
1. In order to solve this linear equation, we'll need to group all the variable terms on one side, and all the constant terms on the other side of the equation. In the problem, term -3 will be moved on the left side. Notice the sign changes when you move it to the left.
17=5k-3 ⇒ 17 + 3 = (5k - 3) + 320 = 5k - 3 + 3
2. Add the numerical terms.
20 = 5k - (3 + 3) = 6. Note: We don't need the six in the 3rd step.
20 = 5k
3. Switch the variable term. (Ex: 3x + 9 ⇒ 9 + 3x)
20 = 5k ⇒ 5k = 205k = 20
4. We will need to isolate the variable, to do that, get rid of the coefficient that it multiples. We can do that by dividing 5 by both sides.
5k/5 ÷ 20/5 = 1k/45k/5
5. We'll need to reduce 5k/5 to its lowest terms. We can divide the factors that appear both in the numerator and denominator. If we look at 5k/5, 5 appears both in the numerator and denominator.
5k/5 ⇒ k = 2²· 5/56. Lastly, we can do the same thing as we did in the 5th step. That'll lead us to k = 2²
7. Solve for 2²
2 x 2 = 4.
Hence, our answer is 4.

last question and i can play D. I. E
Answer:
Choice B
Step-by-step explanation:
6x + 4x^4 - 3x^2 + 7x^4 + 5x^2 + 8x
combine like terms
6x + 8x = 14x
4x^4 + 7x^4 = 11x^4
3x^2 - 5x^2 = 2x^2
14x + 11x^4 + 2x^2

A triangle’s base is 3 feet longer than twice its height, h. To create a new triangle, the base is decreased by 4 feet, and the height is increased by 2 feet. Which expression represents the area of the new triangle?
Answer:
area of the triangle =
[tex] \frac{(x - 4) \times (y + 2)}{2} [/tex]
let base be x and height y
hope it helped
PLS mark BRAINLIEST
Answer:
let height be x
base =2x+3
for new
height =x+2
base=2x+3-4=2x-1
area of new triangle=1/2_newbase×height

I assume you're talking about a fraction,
(2i ²⁰ + i ⁴²) / (i ¹⁰¹ - i ²)
Remember that i ² = -1; from this it follows that
i ³ = i ² × i = -i
i ⁴ = i ³ × i = (-i ) × i = -i ² = -(-1) = 1
i ⁵ = i ⁴ × i = i
i ⁶ = i ⁵ × i = i ² = -1
and so on. In particular, raising i to some integer multiple of 4 reduces to 1.
Using the above pattern, we find
i ²⁰ = 1
i ⁴² = i ⁴⁰ × i ² = 1 × (-1) = -1
i ¹⁰¹ = i ¹⁰⁰ × i = 1 × i = i
So, we have
(2i ²⁰ + i ⁴²) / (i ¹⁰¹ - i ²) = (2 - 1) / (i - (-1)) = 1 / (i + 1)
We can stop here, but usually it's more useful to have complex numbers written in standard a + bi form. To get this result, multiply the numerator and denominator by the complex conjugate of i + 1:
(2i ²⁰ + i ⁴²) / (i ¹⁰¹ - i ²) = 1 / (i + 1) × (-i + 1) / (-i + 1)
… = (-i + 1) / (-i ² + 1²)
… = (-i + 1) / (-(-1) + 1)
… = (1 - i ) / 2
or equivalently,
… = 1/2 - 1/2 i

What is the image of (-8,- 7) after a dilation by a scale factor of 2 centered
at the origin?
Answer: (-16, -14)
==========================================================
Explanation:
To get that result, you multiply each coordinate by the scale factor 2
We have
-8*2 = -16-7*2 = -14So that's why (-8,-7) moves to (-16, -14)
This trick only works if the origin is the center of dilation.

In ΔMNO, the measure of ∠O=90°, the measure of ∠N=48°, and NO = 73 feet. Find the length of MN to the nearest tenth of a foot.
Answer:109.1 feet
Step-by-step explanation:
What function uses the ADJACENT and the HYPOTENUSE?
\text{SOH-CAH-TOA}
SOH-CAH-TOA
\cos N = \frac{\text{adjacent}}{\text{hypotenuse}}=\frac{73}{x}
cosN=
hypotenuse
adjacent
=
x
73
\cos 48=\frac{73}{x}
cos48=
x
73
x\cos 48=73
xcos48=73
Cross multiply.
\frac{x\cos 48}{\cos 48}=\frac{73}{\cos 48}
cos48
xcos48
=
cos48
73
Divide each side by cos 48.
x=\frac{73}{\cos 48}=109.0968\approx 109.1\text{ feet}
x=
cos48
73
=109.0968≈109.1 feet
Type into calculator and roundto the nearest tenth of a foot.
