WILL MARK BRAINLIEST

Answer:

-1

Step-by-step explanation:

What you're gonna do is plug in the values. (i rhymed) The formula is y=mx+b

m = slope

b = y-intercept

y and x are just the y and x values.

1 = 2(1) + b

1 = 2 + b

-2   -2    

-1 = b

That's how you solve for the y-intercept (b) = -1.

Hope this helps and have a great day!

Step-by-step explanation:

Answer:

Step-by-step explanation:

Point-slope form:

The standard point-slope form equation is

[tex]y-y_1=m(x-x_1)[/tex]

where [tex](x_1,y_1)[/tex] are the coordinates and [tex]m[/tex] is the slope/gradient

so for point-slope form we need to find m cause we already have 2 coordinates (-3,5) , (3,3) we can use any one of them in our equation but first we need to find the slope by the formula

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

we use our coordinates to find it and simply plug in the values

[tex]m=\frac{3-5}{3-(-3)} \\m=\frac{-2}{6} \\\\m=\frac{-1}{3}[/tex]

so we get our slope m = -1/3

and simply put m and any one of the coordinates into the standard form

[tex]y-y_1=m(x-x_1)\\y-3=\frac{-1}{3} (x-3)\\3(y-3)=-1(x-3)\\3y-9=-x+3\\3y=-x+12\\y=\frac{-x+12}{3} \\y=\frac{-x}{3} +4[/tex]

Slope-intercept form:

The standard slope-intercept form is

[tex]y=mx+c[/tex]

where m is the slope and c is the y-intercept, we already know the slope is -1/3 from the previous steps but we don't know the y-intercept so lets get started.

y-intercept means the equation intersects the y-axis which means the coordinate should be [tex](0,y)[/tex] so we plug in the slope -1/3 and the coordinate given above (-3,5) , (3,3) in the equation to find the y-intercept that is c. We can you use any one of the two coordinates.

[tex]y=mx+c\\3=\frac{-1}{3}(3)+c \\\\3=\frac{-3}{3} +c\\\\3=-1+c\\c=4[/tex]

so now we found the value of c=4 which is the y-intercept (0,4) and finally our slope-intercept form would be

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

as both form are same but the approach is different this verifies that both our answers are correct.

The slope of the line is -1/3. The equation in the slope-intercept form is y = (-1/3) x + 4.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that,

The line passes through points (-3,5), and (3,3).

The slope of the line is,

m = (y₂-y₁) / (x₂-x₁)

m = (3-5) / (3-(-3)

m = -2 / 6

m = -1 / 3

The standard equation for the line is,

y - y₁ = m (x - x₁)

y - 5 = -1 / 3 (x - (-3)

3(y - 5) = -1(x+3)

3y - 15 = -x -3

x + 3y = -3 +15

x + 3y = 12

3y = -x +12

y = (-1/3) x + 4

Thus, the slope of the line is -1/3. The equation in the slope-intercept form is y = (-1/3) x + 4.

Answer:

The answer is C.

Step-by-step explanation:

I just took the test and i got it right.

Answer:

x = - 10, x = 9

Step-by-step explanation:

Given

x² + x - 90 = 0 ( add 90 to both sides )

x² + x = 90

To complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2([tex]\frac{1}{2}[/tex] )x + [tex]\frac{1}{4}[/tex] = 90 + [tex]\frac{1}{4}[/tex]

(x + [tex]\frac{1}{2}[/tex] )² = [tex]\frac{361}{4}[/tex] ( take the square root of both sides )

x + [tex]\frac{1}{2}[/tex] = ± [tex]\sqrt{\frac{361}{4} }[/tex] = ± [tex]\frac{19}{2}[/tex] ( subtract [tex]\frac{1}{2}[/tex] from both sides )

x = - [tex]\frac{1}{2}[/tex] ± [tex]\frac{19}{2}[/tex] , thus

x = - [tex]\frac{1}{2}[/tex] - [tex]\frac{19}{2}[/tex] = [tex]\frac{-20}{2}[/tex] = - 10

x = - [tex]\frac{1}{2}[/tex] + [tex]\frac{19}{2}[/tex] = [tex]\frac{18}{2}[/tex] = 9

Answer:

95%

Step-by-step explanation:

Data falls within 2 standard deviations from the mean - is calculated using;

μ – 2σ and μ + 2σ .

The mean of this distribution is $25,615 and the standard deviation is $25,333.

μ – 2σ

= $25,615 - 2($25,333)

=$-25051

μ + 2σ

= $25,615 + 2($25,333)

= 76,281

Empirical rule states that: 95% of data falls within 2 standard deviations from the mean

Hence, 95% the sample had total personal incomes within two standard deviations of the mean.

BRAILIEST? PWEASE

Answer:

0.67894

Step-by-step explanation:

Given that :

Lifespan of zebra is normally distributed :

Mean(μ) = 20.5

Standard deviation (σ) = 3.93

Probability of Zebra living between 16. 6 to 24.4 years

Using the empirical rule :

Z = (x - μ) / σ

For : P(Z < x ) ; X = 16.6

Z = (16.6 - 20.5) / 3.93

Z = - 0.9923

P(Z < - 0.9923) = 0.16053

For : P(Z < X) ; X = 24.4

Z = (24.4 - 20.5) / 3.93

Z = 0.9923

P(Z < 0.9923) = 0.83947

Hence,

0.83947 - 0.16053 = 0.67894

Answer:

68%

Step-by-step explanation:

Answer:

3 is 68 degrees

Step-by-step explanation:

So 7 is 22

2 is equal to seven so that is 22 too

it's a 90 degree angle

so 90-22=68

so that is how i got 3 is 68 degrees

Answer:

m < 3 = 68°

Step-by-step explanation:

Given m<7 = 22°, apply the Alternate Interior Angles Theorem to solve for m<5 which is also 22°.

You can use the Vertical Angles Postulate to find the m<2 which is also 22°.

Given that m || n and y is perpendicular to m, making y also perpendicular to n.

Since x and y are parallel, x is also perpendicular to n.

This means m<2 + m<3 = 90°

22° + m<3 = 90°

m<3 = 68°

Answer:

She spent [tex]5\frac{5}{24} days[/tex] on her English paper and math test combined than on her science project

Step-by-step explanation:

Suzy spent time on English paper =[tex]6\frac{7}{8}=\frac{55}{8}[/tex]

She spent time on science project = [tex]3\frac{1}{6}=\frac{19}{6}[/tex]

She spent on Maths test =[tex]1\frac{1}{2}=\frac{3}{2}[/tex]

She spent on her English paper and math test combined =[tex]\frac{55}{8}+\frac{3}{2}=\frac{67}{8}[/tex]

Suzy spend time more on her English paper and math test combined than on her science project = [tex]\frac{67}{8}-\frac{19}{6}=5\frac{5}{24}[/tex]

Hence She spent [tex]5\frac{5}{24} days[/tex] on her English paper and math test combined than on her science project

Step-by-step explanation:

To name an angle, you have to lokk at the three points that create it. There is the vertex and two 'arms' or lines. In the image below, the angle can be called AOB or BOA. However, you can NEVER name an angle by saying the vertex point first. I hope this helps!
