Answer:

69

Step-by-step explanation:

Answer:

(1) First pair; (2, 3), (7, 3), d₁ = 5

(2) Second pair; (-2, 5), (-2, -3), d₂ = 8

(3) Third pair; (-8, 5), (-2, 5), d₃ = 6

(4) Fourth pair; (-9, 1), (6, 1), d₄ = 15

Step-by-step explanation:

Given pair of points;

(1)  (2, 3), (7, 3)

(2) (-2, 5), (-2, -3)

(3) (-8, 5), (-2, 5)

(4) ) (-9, 1), (6, 1)

The distance between each pair of points is calculated as follows;

[tex]d = \sqrt{(y_2-y_1)^2 + (x_2-x_1)^2}[/tex]

(1) first pair; (2, 3), (7, 3)

[tex]d_1 = \sqrt{(3-3)^2 + (7-2)^2} \\\\d_1 = 5[/tex]

(2) second pair; (-2, 5), (-2, -3)

[tex]d_2 = \sqrt{(-3-5)^2 + (-2-(-2))^2}\\\\d_2 = \sqrt{(-3-5)^2 + (-2+2)^2} \\\\d_2 = 8[/tex]

(3) Third pair; (-8, 5), (-2, 5)

[tex]d_3 = \sqrt{(5-5)^2 + (-2-(-8))^2}\\\\d_3 = \sqrt{(5-5)^2 + (-2+8)^2} \\\\d_3 = 6[/tex]

(4) Fourth pair; (-9, 1), (6, 1)

[tex]d_4 = \sqrt{(1-1)^2 + (6-(-9))^2}\\\\d_4 = \sqrt{(1-1)^2 + (6+9)^2} \\\\d_4 = 15[/tex]

Answer:

6m - 15 = 9m+9

Step-by-step explanation:

Looking at option b;

6m - 15 = 9m+9

Collect the like terms

6m-9m= 9 + 15

-3m = 24

Divide both sides by -3

-3m/-3 = 24/-3

m = -8

Hence the equation that has -8 as solution is 6m - 15 = 9m+9

Answer:

yup its right

Step-by-step explanation:

Answer:

x = 3

Step-by-step explanation:

use the substitution method

since y = 6 fill in 6 for y in y = -5x + 21

6 = -5x + 21

subtract 21 from both sides

-15 = -5x

divide each side by -5

3 = x

Answer:

Simplify  {4}^{2}42  to  1616.

-16+2\times -4\times -5-2\times {2}^{3}−16+2×−4×−5−2×23

Simplify  2\times -42×−4  to  -8−8.

-16-8\times -5-2\times {2}^{3}−16−8×−5−2×23

Simplify  8\times -58×−5  to  -40−40.

-16-(-40)-2\times {2}^{3}−16−(−40)−2×23

Use Product Rule: {x}^{a}{x}^{b}={x}^{a+b}xaxb=xa+b.

-16-(-40)-{2}^{4}−16−(−40)−24

Simplify  {2}^{4}24  to  1616.

-16-(-40)-16−16−(−40)−16

Remove parentheses.

-16+40-16−16+40−16

Simplify  -16+40−16+40  to  2424.

24-1624−16

Simplify.

Answer:

First option,   [tex]\frac{-2y+5x}{3x-2y}[/tex]

Step-by-step explanation:

Simplify the fraction. To make the process of solving easier, we can multiply both the numerator and denominator by x and y to get rid of the fractions as seen below. This is because the variables in the denominators of the fractions will cancel out with either the matching x or y in the numerators.  

[tex]\frac{\frac{-2}{x} +\frac{5}{y} }{\frac{3}{y}-\frac{2}{x} } \\=\frac{(\frac{-2}{x} +\frac{5}{y})xy }{(\frac{3}{y}-\frac{2}{x})xy }\\=\frac{-2y+5x}{3x-2y}[/tex]

Thus, the first option is correct.

Step-by-step explanation:

Answer: 460 students

Step-by-step explanation:

Based on the information given in the question, let the total number of students that attend I.S. 59 be represented by x.

Since we've been given the information that 230 signed up for the school picnic which was 50% of all students in the school. Then, the students in the school will be:

= 50% of x = 230

0.5 × x = 230

0.5x = 230

x = 230/0.5

x = 460

Therefore, 460 students attend the school.

Answer:

(a+6)(a-2)=a^2-4a-12

Step-by-step explanation:

Answer:

x=16 or any value less than 16.

Step-by-step explanation:

16x5=80 and subtract 10 you get 70. X has to equal a value that makes the whole left side of the equation "smaller" than the irght side, and 16 or any value less than that would accomplsish this.

.Step-by-step explanation:

Answer:

1) -15+8i

2) x^2+2x-5

Step-by-step explanation:

1) apply perfect square formula

(4i)^2+2*4i1+1^2

then simplify

2)remove parentheses

x+1+(x-2)(x+3)

expand (x-2)(x+3)

x+1+x^2+x-6

simplify x+1+x^2-6 = x^2+2x-5

Answer:

C. Log base b (a) - Log base b (d)

Step-by-step explanation:

In logarithm, log means index or exponent. It can be explained with following example. Consider 2^5 = 32

here index = log = 5 so you can write the log of 32 = 5

Consider 64/16 = 4

now 64 = 2^6 and 16 = 2^4

We can write log 2(64) = 6 and log2(16)=4

Now log 64/16= log 4= 2

Also log2(64)-log2(16)=6-4=2

Therefore

Log base b (a/d) = Log base b (a) - Log base b (d)

Answer: 21 questions

Step-by-step explanation:

Turn it into a number sentence.

72% of x amount of questions is 15

0.72(x) = 15. Divide both sides by 0.72

x= 20.83333 round to nearest whole number

x= 21 questions
