Write the equation of the line that passes through the points (-1, 2) and (6, 3) in slope-intercept form. Step 1: Choose (X1,Y1)

Ivan

Answer:

Step-by-step explanation:
Given that the line passes through two points (-1,2) and (6,3)
Slope of the line passing through (x1,y1) and (x2,y2) is y2-y1
x2-i1

Hence slope of our line =
(3-2)/(6+1) = 1/7
So in slope intercept form the equation would be
y = 1/7 x +C
to find C
Since (-1,2) lies on the line substitute these in the line equation
2 = 1/7(-1)+c
C = 2+1/7 = 15/7
Hence equation in slope intercept form is y=x/7+15/7

Pam spelled 68 of 100 words correctly on the pretest. How many words did she miss? If she learns 8 of those each day, how long w

Fofino [41]

Answer:

Pam missed 32 words in her pretest.

It will take 4 days for Pam to learn all missed words.

Step-by-step explanation:

Given:

Number of words spelled correctly = 68

Total number of words on the pretest = 100

We need to find the number of words she missed.

Solution:

now we can say that;

Number of words she missed can be calculated by subtracting Number of words spelled correctly from Total number of words on the pretest.

framing in equation form we get;

Number of words she missed = $100 -68 =32\ words$

Hence Pam missed 32 words in her pretest.

Now Given:

Number of words missed learned each day = 8

Total number of words missed = 32 words.

We need to find how long will take to learn them all.

now we can say that;

days required to learn missed words is equal to total number of words missed divided by Number of words missed learned each day.

framing in equation form we get;

Days required to learn missed words = $\frac{32}{8}=4\ days$

Hence It will take 4 days for Pam to learn all missed words.

Evaluate the expression,<br> if x = 9, y = 3, and z = 5.<br> z2 • (x-y)

Bad White [126]

$\huge\text{Hey there!}$

$\mathsf{z^2 \times (x - y)}$

$\mathsf{= 5^2 \times (9 - 3)}$

$\mathsf{= 5 \times 5 \times (9 - 3)}$

$\mathsf{= \bold{25}\times(9 - 3)}$

$\mathsf{= 25\times \bf 6}$

$\mathsf{= \bf 150}$

$\huge\text{Therefore, your answer should be: }$

$\huge\boxed{\frak{150}}\huge\checkmark$

А What is the value of x? <br><br>Enter your answer in the box. <br><br>X=

MariettaO [177]

Answer:

x = 25

Step-by-step explanation:

Since ∠ A = ∠ B then the triangle is isosceles and AC = BC , that is

4x - 30 = 2x + 20 ( subtract 2x from both sides )

2x - 30 = 20 ( add 30 to both sides )

2x = 50 ( divide both sides by 2 )

x = 25
