A line has a gradient of 4 and passes through the point (1, 9). What it's equation?
answer: y - 4x - 5= 0
Step-by-step explanation:
y - y1 = m(x - x1)y - 9 = 4( x - 1)y - 9 = 4x - 4y - 4x = -4 + 9y - 4x = 5y - 4x - 5 = 0A 3-column table with 4 rows. Column 1 is labeled Inequality with entries 8 greater-than 2, negative 10 less-than negative 5, 16 greater-than negative 40, negative 8 less-than 4. Column 2 is labeled Multiply each side by: with entries negative 2, 5, 8, negative 4. Column 3 is labeled New Inequality with entries A, B, C, D.

−3x − 8y = 20 −5x + y = 19 solved by substitution
Delete as this is the wrong answer. Made a typo in the answer.
Answer:
x = [tex]\frac{-212}{3}[/tex]
y = 24
Step-by-step explanation:
-3x - 8y = 20 .... (1)
-5x + y = 19 .... (2)
What we can do is take the (2) equation
-5x + y = 19
and solve for y by adding 5x to both sides
y = 24
now that we have y we substitute it in for y in equation (1)
-3x - 8(24) = 20
-3x - 192 = 20
we want to solve for x so we need to get its self.
add 192 to both sides
-3x = 212
now we divide both sides by -3. It's going to be a fraction.
x = [tex]\frac{-212}{3}[/tex]
Answer:
x=-4
y=-1
Step-by-step explanation:
-3x-8y=20
-5x+y=19
rewrite for y:
y=19+5x
substitute y
-3x-8(19+5x)=20
-3x-152-40x=20
-3x-152-40x+152=20+152
-43x=172
-43x/-43=172/-43
x=-4
substitute x
-5(-4)+y=19
20+y=19
y=-1
check:
-3(-4)-8(-1)=20
12+8=20
-5(-4)+-1=19
20-1=19

Write an inequality that could represent the possible values for the number of tables sold, tt, and the number of chairs sold, cc, that would satisfy the constraint.
The inequality that represents the possible values for the number of tables sold, tt, and the number of chairs sold, cc is $200cc + $650tt > $12,000.

Antonia incorrectly solves the equation −2(14−54a)=6 . Her work is shown below.
Determine which of her steps are correct based on the work in the previous step. Drag and drop Yes or No into each box to show if her math is correct for each step.
Then, drag and drop the correct solution into the box to make the statement true.
Answer:
For the yes/no bit:
step 1: no
step 2: no
step 3: yes
step 4: yes
step 5: no
for the final answer bit: a = 2 3/5 (the last option)
Step-by-step explanation:
yes/no bit:
step 1 is wrong because she didn't multiply [tex]-\frac{5}{4}a[/tex] by -2
step 2 is wrong because she subtracted 1/2 instead of adding it
step 3 is correct because 6 - 1/2 = 11/2
step 4 is correct because she correctly multiplied both sides by 4
step 5 is wrong because she added 5 instead of dividing by -5.
for the final answer bit, I've attached an image below with my working out. hope this helps!
