Mathematics

gladu [14]3 years ago
6 0

Answer:

4a - 3b + 5 = 5

Step-by-step explanation:

Express the ratios in fractional form

\frac{a}{3} = \frac{b}{4} ( cross- multiply )

4a = 3b ( subtract 3b from both sides )

4a - 3b = 0

Then

4a - 3b + 5 = 0 + 5 = 5

What is the distance rounded to the nearest tenth between the points(-5, 3) and (1, -1)?
kakasveta [241]

7.2 units is the distance between the two points (-5,3) and (1, -1).

The formula used for determining the distance between two points is shown below. In case this equation is used for finding the distance between the origin and a point, the value of x1 and y1 would just be equal to zero.

distance = \sqrt{(x2-x1)^{2}+(y2-y1)^{2}  }

The given points can be directly substituted for the formula.

Let: x2= 1, x1= -5, y2= -1, and y1= 3

distance = \sqrt{[1-(-5)]^{2} + (-1 -3)^2 }

distance = \sqrt{(6)^2+(-4)^2}

distance = \sqrt{52} or 7.21 units

When rounded to the nearest tenth, the distance between the two points would be 7.2 units.

For more information regarding the distance between points, please refer to the link brainly.com/question/23848540.

Help needed!! Don’t know how to do!!
Aleks [24]

Answer:

D,0,2,-2

Step-by-step explanation:

2x^5-3x^3-20x=0

x(2x^4-3x^2-20)=0

x=0

or 2x^4-3x^2-20=0

put x²=t

2t²-3t-20=0

-20×2=-40

8-5=3

8×-5=-40

2t²-(8-5)t-20=0

2t²-8t+5t-20=0

2t(t-4)+5(t-4)=0

(t-4)(2t+5)=0

t=4

x²=4

x=2,-2

t=-5/2

x²=-5/2

it gives imaginary  root. so real rational roots are 0,2,-2

Tara received 28 out of 35 points on her last math test. What percentage score did the teacher record in her grade book for Tara
ZanzabumX [31]

Answer:

80%

Step-by-step explanation:

28/35 = 0.8

Divide. Convert a decimal to a percent by multiplying times 100.

0.8 × 100 = 80

Tara earned an 80%

You could use a calculator as described above or using mental math or pencil and paper:

28/35 = 4/5

Simplify.

4/5 = 8/10 = 80/100

Percent means per hundred, change 28/35 to hundredths as above.

Tara (still) gets an 80%.
