Answer:

[tex]y=-\displaystyle\frac{4}{5}x+\displaystyle\frac{3}{5}[/tex]

Step-by-step explanation:

Hi there!

Linear equations are typically organized in slope-intercept form: [tex]y=mx+b[/tex] where m is the slope of the line and b is the y-intercept (the value of y when the line crosses the y-axis).

1) Determine the slope (m)

[tex]m=\displaystyle\frac{y_2-y_1}{x_2-x_1}[/tex] where two points that fall on the line are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]

Plug in the given points (2, -1) and (-3, 3):

[tex]m=\displaystyle\frac{-1-3}{2-(-3)}\\\\m=\displaystyle\frac{-4}{2+3}\\\\m=-\displaystyle\frac{4}{5}[/tex]

Therefore, the slope of the line is [tex]-\displaystyle\frac{4}{5}[/tex]. Plug this into [tex]y=mx+b[/tex]:

[tex]y=-\displaystyle\frac{4}{5}x+b[/tex]

2) Determine the y-intercept (b)

[tex]y=-\displaystyle\frac{4}{5}x+b[/tex]

Plug in one of the given points and solve for b:

[tex]-1=-\displaystyle\frac{4}{5}(2)+b\\\\-1=-\displaystyle\frac{8}{5}+b\\\\b=\displaystyle\frac{3}{5}[/tex]

Therefore, the y-intercept is [tex]\displaystyle\frac{3}{5}[/tex]. Plug this back into [tex]y=-\displaystyle\frac{4}{5}x+b[/tex]:

[tex]y=-\displaystyle\frac{4}{5}x+\displaystyle\frac{3}{5}[/tex]

I hope this helps!

Answer:

y= -0.8x + 0.6

Step-by-step explanation:

Answer:

Step-by-step explanation:

we have 2 pts (-4,2) and (6,-3)

slope = [tex]\dfrac{-3-2}{6-(-4)}=\dfrac{-5}{10}=-\dfrac{1}{2}[/tex]

so: [tex]y=-\dfrac{1}{2}+b[/tex]

plug in any point:

[tex]-3=-\dfrac{1}{2} * 6 +b[/tex]

[tex]b=0[/tex]

so, [tex]y=-\dfrac{1}{2} x[/tex]

Answer:

8

Step-by-step explanation:

-7 · ? = -56

-7 · 8 = -56

so -56 ÷ -7 = 8

Answer:

x = 16

Step-by-step explanation:

The triangle in question is an isosceles triangle which means :

m<Q = m<P and the sum of interior angles in a triangle is equal to 180

so we can find the value of x using the following equation:

5x - 2 + 3x + 3 + 3x + 3 = 180 add like terms

11x + 4 = 180 subtract 4 from both sides

11x = 176 divide both sides by 11

x = 16

Answer:

x= 80

y= 77

180-23=157

80+77=157

157+23=180

Answer:

y = -1/3x - 1/3

Step-by-step explanation:

x + 3y = -5

3y = -x - 5

y = -1/3x -5/3

Slope - 1/3

Point: (-7,2)

y- intercept = 2 - (-1/3)(-7) = 2 - 7/3 = -1/3

Answer:

1/3

Step-by-step explanation:

9/27 simplified is 1/3

Answer:

yes it can be done.

Answer:

8.2 cm

Step-by-step explanation:

The given shows us that we will be using CAH from SOH CAH TOA where

cos theta = adjacent / hypotenuse

in this case it will be

. cos 47 = h / 12

we want h to be the subject so we will multiply both sides by 12

. h = cos 47 * 12

. h = 8.184

now all you have to do is round to 1d.p

. h = 8.2cm

Step-by-step explanation:

[tex] = {( - 2 {a}^{2} {b}^{4} )}^{3} [/tex]

[tex] = {( - 2)}^{3} {a}^{2 \times 3} {b}^{4 \times 3} [/tex]

[tex] = - 8 {a}^{6} {b}^{12} [/tex]

Option → D

Let's simplify step-by-step.

5p+17.6−(−3p+12.2)

Distribute the Negative Sign:

=5p+17.6+−1(−3p+12.2)

=5p+17.6+−1(−3p)+(−1)(12.2)

=5p+17.6+3p+−12.2

Combine Like Terms:

=5p+17.6+3p+−12.2

=(5p+3p)+(17.6+−12.2)

=8p+5.4

Answer:

=8p+5.4

Answer:

475

Step-by-step explanation:

use x for the big market

so small market is 96/(1/5)

so its 475

Answer:

a-2 is the answer for the problem

Ouch that question doesn't give much information for me to understand what I need to do sorry lol

Answer:

(a) There are 3 terms.

(b) There are 4 factors in the first term, which are 1, 2, 4, and 8.

(c) The term 16 is a constant.

Answer:

exponential growth

Step-by-step explanation:

a value is greater than 1, therefore it is growth

Answer: 1.

Step-by-step explanation:

First, rewrite the equation in slope-intercept form to find the slope. 5x + 2y = 9 2y = -5x + 9 y

Step-by-step explanation:

Price = $1.70

V = 500ml → Litre

V = 500 ÷ 1000

V = 0,5 L

= $1.70 / 0,5L

= $1.70 × 2 / 0,5 × 2

= $3.40/L

Option → C

Answer:

$3.40

Step-by-step explanation:

As seen on image the price for 500ml is $1.70

1L = 1000ml so to find how much a Litre cost we need to multiply the given price by 2

1.70 x 2 = $3.40 is the answer to your question.

Answer:

i'll help

Step-by-step explanation:

A number x is 8 less than 5 times the same number x. This means that :

x +8= 5x

We can also write :

5x = x +8

5x - x = x + 8 - x

4x = 8

4x / 4 = 8 / 4

x = 2

R-squared is a statistical measure that represents the proportion of the variance for a dependent variable that's explained by an independent variable.

Answer:

4x2 - 4x + 4.

Step-by-step explanation:

x2 - 3x - 4 -  (x - 3x2 - 8)        Distribute the negative over the parentheses:

= x2 - 3x - 4 - x + 3x2 + 8       Bring like terms together:

= x2 + 3x2 - 3x - x - 4 + 8

= 4x2 - 4x + 4.
