Step-by-step explanation:
The line passing through the points (-2, 10) and (5, -11)
y-intercept = (0, 4)
x-intercept = (3/4, 0)
Step-by-step explanation:1 - Find the slope
[tex]slope = m = \frac{rise}{run} = \frac{y_2~-~y_1}{x_2~-~x_1} = \frac {-11-10}{5-(-2)} = \frac {-21}{7} = -3[/tex]
2 - Plug the slope into y = mx + b and substitute a point into x and y to find the y-intercept, b, by isolating it.
y = mx + b
y = -3x + b
10 = (-3)(-2) + b
10 = 6 + b
-6 -6
4 = b
y-intercept = (0, 4)
3 - Rewrite the completed formula
y = -3x + 4
4 - Substitute 0 in for y to find the x-intercept
0 = -3x + 4
-4 - 4
-4 = -3x
-4/-3 = -3x/-3
4/3 = x
x-intercept = (4/3, 0)

Answer:
9) -25/21
11) 14
Step-by-step explanation:
In each case, subtract the y-coordinates. Subtract the x-coordinates in the same order. Divide the difference in y by the difference in x.
9)
y-coordinates: -10 - 15 = -25
x-coordinates = 6 - (-15) = 21
slope = (difference in y)/(difference in x) = -25/21
11)
y-coordinates: -20 - 8 = -28
x-coordinates = 3 - 5 = -2
slope = (difference in y)/(difference in x) = -28/(-2) = 14

A taxi charges $1.25 per mile and a flat fee of $2.75. How much would Maria pay for a 5 mile ride?
Answer:
9
Step-by-step explanation:
so you write the expression 2.75+1.25x= ?
If we subsitute the X for 5(miles) the we'll have the expression 2.75+1.25(5)= ?
and if you simplify that you will get 9.

A runner saved $25 when he purchased a pair of tennis shoes on sale. If the sale price was 35% off the regular price, what was the regular price of the tennis shoes?
Given:
Amount saved in sale = $25
Sale price was 35% off the regular price.
To find:
The regular price of the tennis shoes.
Solution:
Let the regular price of the tennis shoes be x.
Sale price was 35% off the regular price.
[tex]Discount=\dfrac{35}{100}x[/tex]
Amount saved in sale = $25
[tex]0.35x=25[/tex]
Divide both sides by 0.35.
[tex]x=\dfrac{25}{0.35}[/tex]
[tex]x=71.42857[/tex]
[tex]x\approx 71.43[/tex]
Therefore, the regular price of the tennis shoes is $71.43.

What is 17 + -176 + 19 + 14 - -1723 + 3 / 9.
Order of operations.
Answer:
1597.3333333333
Step-by-step explanation:
= 17-176+19+14+1723+3/9.
= 17-176+19+14+1723+0.33333333333333
= -159+19+14+1723+0.33333333333333
= -140+14+1723+0.33333333333333
= -126+1723+0.33333333333333
= 1597+0.33333333333333
= 1597.3333333333

Would the simplified version of this be 5x^4+7x?
Answer:
5x⁴ + 7x or x(5x³ + 7 )
Step-by-step explanation:
Given expression:
5x⁴ - 7(-x )
To simplify this expression, we have to follow the order of operation PEMDAS;
Parentheses, Exponents, Multiplication, Division, Addition and Subtraction
5x⁴ - 7(-x ) = 5x⁴ + 7x
Since x is common to both terms;
= x(5x³ + 7 )
So the simplified version can be 5x⁴ + 7x or x(5x³ + 7 )
