Answer:
y = - [tex]\frac{9}{5}[/tex] x - 4
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - [tex]\frac{9}{5}[/tex] and c = - 4 , thus
y = - [tex]\frac{9}{5}[/tex] x - 4 ← equation of line
Anybody know the slope to this?
Select the graph that matches the function y = 3x + 7.
Select True or False. (1 point) The expression 3x − 4(2x − 5) is equivalent to the expression 20 − 5x. True False
Answer:
yes
Step-by-step explanation:
because of the way this is put the result simplified would be 3x-8x-20
3-8=-5
so the answer is 20-5x
x=0.25 btw
this is an identifying functions lesson someone please help

5. Two sides of a right triangle are 8 inches and 12 inches. What is the length of the Hypotenuse
Answer:
19.7ft
Step-by-step explanation:
o^2+a^2=h^2
\dpi{100} h^{2}=(10ft)^{2} +(17ft)^{2}
h^2=100ft^2+289ft^2
h=389ft^2−−−−−√
→19.7ft
Answer:
Step-by-step explanation:
a^2 + b^2 = c^2
where a and b are the legs of the triangle and c is the hypotenuse
so 8^2 + 12^2 = c^2
64 + 144 = c^2
208 = c^2
take the square root of both sides
c = 14.422
Write the equation of the line that goes through (2, 1) and is PARALLEL to 4x - 2y = 3 pls help asap! i have more questions like this also if someone could help me out
Answer:
Step-by-step explanation:
4x-2y=3
Get into y=mx+b
-4x on each side
Then divide by -2
y=2x- 1.5
Now if a line is parallel to another line the slope will be the same. If perpendicular the slope will be the negative reciprocal. As you said it is parallel the slope is 2.
y = mx+b
y = (slope)x + y-intercept
y= 2x + 1
Sorry if it is wrong but I hope it is right
What’s the value of y?
Answer:
c. 19
Step-by-step explanation:
This model is describing a function. You put in a number for x, in this case, the input of 7 on the side. You solve the equation with that x-value to get a y-value/output.
x=7
y=3x-2
y=3(7)-2
y=21-2
y=19

- If the exterior angle of the triangle measure 133°, and its remote interior
angles measure x° and (2x-5)°, what is the value of x?
a. x = 61.7°
b. x = 133°
c. x = 47°
d. x = 46°
Answer:
D
Step-by-step explanation:
Mathematically;
the exterior angle is the sum of the two remote interior angles
Thus;
x + 2x-5 = 133
3x-5 = 133
3x = 133 + 5
3x = 138
x = 138/3
x = 46

Carlo and Helen spend the same amount of money on art supplies. Carlo buys 4 glue
sticks and spends $3 on glitter. Helen buys 2 glue sticks, and she spends $3.75 on tape
and $2.75 on paint. What is the cost, x, of each glue stick?
Since we don't have a total cost we will write an equation that will allow us to find the cost of x. The equation is 4x= 2x + $3 + $3.75 + $2.75. Now that we have our equation we are going to start by adding 3, 3.75, and 2.75. When added together, they come out with a total of 9.5. Now the equation becomes 4x= 2x + $9.50. Since we have our new equation we are going to subtract 2x from both sides of the equation. We now have the equation 2x= $9.50. Finally, you will divide both sides by 2. This leaves us with the final outcome x= $4.75. This means that one glues stick cost $4.75. Let's check by substituting $4.75 as the value of x in the expressions 4x is Carlo's total and 2x + $3 + $3.75 + $2.75 is Helen's total. First we do 4x, 4 multiplied by 4.75 equals 19, so Carlo spent $19 on art supplies. Now we do 2x + $3 + $3.75 + $2.75, which is 9.5 added to 9.5 and equals 19. So Helen spent $19 on art supplies. This proves that the cost of one glue stick, x, is equal $4.75.
3(x - 2) + 4(2x - 6) = 6(x - 4) + 8(2x + 1)
Answer:

PROVE ALGEBRAICALLY THAT 0.5 = 5/9
Answer:
See Below.
Step-by-step explanation:
Let:
[tex]0.\overline{5}=n[/tex]
If we multiply both sides by 10, we get:
[tex]5.\overline{5}=10n[/tex]
Now, we will subtract n from both sides:
[tex]5.\overline{5}-n=10n-n[/tex]
On the left, we can replace the n:
[tex]5.\overline{5}-.\overline{5}=10n-n[/tex]
Subtract:
[tex]5=9n[/tex]
Divide both sides by 9:
[tex]n=\frac{5}{9}[/tex]
Hence:
[tex]n=0.\overline{5}=\frac{5}{9}[/tex]
Carrie wants to conduct a randomized experiment on 50 articles of her dirty clothing to see if detergent A or detergent B cleans better. Which of the following best describes the method for randomization using slips of paper within this experiment?
A. Label each article of clothing with a number from 1 to 50, and write those numbers on identical slips of paper. Shuffle the slips of paper and choose 25 slips of paper to wash with detergent A and the remaining slips to wash with detergent B.
B. Label each article of clothing with a number from 1 to 50, and write those numbers on identical slips of paper. Shuffle the slips of paper and choose 25 of them. The numbers on those slips will represent the items that will be washed with detergent A and the remaining items will be washed with detergent B.
C. Label each article of clothing with a number from 1 to 50, and write those numbers on identical slips of paper. Carefully place the slips of paper in a stack and choose the top 25 slips of paper. The numbers on those slips will represent the items that will be washed with detergent A and the remaining items will be washed with detergent B.
D. Label each article of clothing with a number from 1 to 50, and write those numbers on different-sized slips of paper. Use large slips for pants, medium-sized slips for shirts, and small slips for shorts. Shuffle the slips of paper and choose 25 slips of paper. The numbers on those slips will represent the items that will be washed with detergent A and the remaining items will be washed with detergent B.
E. Label each article of clothing with a number from 1 to 50, and write those numbers on identical slips of paper. Shuffle the slips of paper and choose 25 of them. The numbers on those slips will represent the items that will be washed with detergent A. Replace those slips and shuffle all 50 slips again and choose 25 slips again. The numbers on those slips will represent the items that will be washed with detergent B.
Answer:
b
Step-by-step explanation:
Because if it has to be random then you wouldn't know what 25 numbers you were going to pull out.
