Please help, I WILL MARK YOU BRAINLIEST IF U GET IT RIGHT AND GIVE A THANKS IVE BEEN STUCK ON THIS FOR A WHILE PLEASE :(

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

hope this helps :)

Answer:

(x + 3) + (x + 3) + (x + 3) + (x + 3)

Step-by-step explanation:

Repeated addition:

4(x + 3), means that (x + 3) is added by itself 4 times.

So:

(x + 3) + (x + 3) + (x + 3) + (x + 3)

The length of AC is 6.4 unit.

The correct option is C.

We have the figure from which we can say that

BD is the diameter which is

= 4.8 + 1.6

= 6.4 unit long.

Now, AC is the chord.

As, the distance between the two opposite point the the surface of circle would be same.

Then, the length of AC = length of BD

Thus, the length of AC is 6.4 unit.

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:

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.

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:

n = 7 1/3 weeks

Step-by-step explanation:

Amount Jabari wants to save = $66

Amount he earns per week = $9

Hours worked per week = 2 hours

How many weeks will it take him to save $66?

Let

n = number of weeks will it take him to save $66

66 = 9n

n = 66/9

n = 7 3/9

n = 7 1/3 weeks

Or

n = 7.33 weeks

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

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)
