y = -1/4x + 4
Find an equation for the line with slope m=4/7 and which goes through the point (21,-7)
Answer:
y=4/7x-19
Step-by-step explanation:
So the equation is :
y-[tex]y^{1}[/tex]=m(x-[tex]x^{1}[/tex])
m= slope
y+7=4/7(x-21)
y=4/7x-19

Integrated math 2 NEED HELP ASAP
Answer:
56
Step-by-step explanation:
Since the 2 triangles are congruent, the ratio of their sides are also equal. Therefore, we can set up an equation:
[tex]\frac{10}{16}=\frac{3x+2}{5x+1}\\\frac{5}{8}=\frac{3x+2}{5x+1}\\5(5x+1)=8(3x+2)\\25x+5=24x+16\\x=11[/tex]
Now that we know x, we can plug in x as 11 into the expression of DE to solve for DE:
5*11+1

What is the slope intercept form of this line?
Answer:
the desired equation is y = (-3/4)x + 7
Step-by-step explanation:
If you start at (0, 7) and move along the line to (4, 4), you'll see that x increases by 4 (this is the 'run') and y decreases by 3 (this is the 'rise'). Thus, the slope of this line is m = rise/run = -3/4.
Let's use this m = -3/4 and the point (0, 7) to write the equation of this line.
(0, 7) is actually the y-intercept.
Thus, the desired equation is y = (-3/4)x + 7.

What trait do animals and protists have in common? A. both animals and protists are sometimes made up of many cells B. both animals and protists have cells with a nucleus C. neither animals nor protists can make their own food
(Pls answer I’ll mark brainliest
Protozoa are protists that resemble animals. Single-celled eukaryotes called protozoa have several characteristics in common with animals, both animals and protists have cells with a nucleus, hence option B is correct.
What is eukaryotes?Eukaryota is a varied domain of creatures whose cells have a nucleus, and its members are referred to as eukaryotes. Eukaryotes include all animals, all plants, all fungi, and many unicellular creatures.
They, along with the two categories of prokaryotes, the bacteria and the archaea, make up a significant group of living organism.
A eukaryotic organism that isn't an animal, a plant, or a fungus is considered a protist. Protists do not constitute a natural group, or clade, despite the likelihood that they have a common ancestor with other eukaryotes.
Therefore, option B is correct.

3. 19a - 7 - 3a + 12a
4. 6(x - 3) + ( 2x - 9)
5. (3x + 8) - 6 (2.5x - 3)
Answer:
1. n = 1/2
2. m = 5/3 or 1 2/3
3. a = 1/4
4. x = 27/8
5. x = 13/6
Step-by-step explanation:
I'm just going to explain step 5 as that is what you specifically needed help with.
First, simplify the second term of the equation:
-6(2.5x-3)
= -15x + 18
(this was done by multiplying -6*2.5x which is 15x and -6(-3) which is 18)
Now, add this simplified second term back to the first term:
3x + 8 - 15x + 18
(the parentheses are unnecessary now because it is all just addition and subtraction, so the order doesn't matter)
Simplify:
-12x + 26 = 0
= -12x = -26
= x = -26/-12
= x = 13/6

Triangle FUN, with vertices F(−2, 4), U(0, −5), and N(−3, −8) was dilated to form triangle PET with vertices P(−1.6, 3.2), E(0, −4), and T(−2.4, −6.4).Which scale factor was used? A. 1.25
B. −1
C. 2/3
D. 0.8
Suppose these statements about two triangles are
true:∠G=∠S,∠R=∠,and ∠M=∠N. Which statement is correct? Select all that apply.
A.The sides are congruent.
B.The sides are proportional.
C. ΔGRM is similar to ΔNST
D. ΔMGR is similar to ΔNST
Answer:
For first question answer is D.0.8
For second question answer is D.ΔMGR is similar to ΔNST.
Step-by-step explanation:
Here triangle FUN is dilated to get triangle PET
So, let's take F and P.
F(-2,4) and P(-1.6, 3.2)
Let's find the scale factor by dividing the coordinates.
Scale factor =[tex]\frac{-1.6}{-2} =0.8[/tex]
Using y coordinates of the same points
Scale factor =[tex]\frac{3.2}{4} =0.8[/tex]
So, scale factor is 0.8
Now, for the second problem
<G= <S
<R= <T
<M=<N
So, the corresponding angles are congruent when two triangles similar.
So, we can say ΔMGR is similar to ΔNST.
Miss Bloom's 5 $45.30 on art supplies if she turns 7% tax how much total money did she spend
Answer:
l
Step-by-step explanation:
Answer:
Miss Bloom spent $48.47 in total
Step-by-step explanation:
turn 7% into a decimal --> 0.07
multiply the cost of art supplies by the tax % (in decimal form)
45.30(0.07) = 3.171
add 3.171 to the original cost of art supplies
45.30 + 3.171 = 48.471
round to the nearest hundreths place (since money typically only has 2 decimal places)
48.471 --> 48.47
therefore, miss bloom spent $48.47 in total

nathan packs 25 boxes in 2 hours how many can he pack in 30 min shfit
Answer: 6
Step-by-step explanation:
30 minutes is a quarter of 2 hours, so if he can pack 25 boxes in 2 hours, he can pack a quarter of that in 30 minutes. A quarter of 25 is 6.25 cant pack half a box, it’s a whole box or nothing. So you round down to 6 boxes. 6 boxes is your answer.
Laura works in a furniture store. She earns $160 a week plus 6% of all sales over $2,000. One week in January, Laura’s total sales were $9,400. What were Laura’s earnings for that week?
$9,400 * 0.06 = $564
$564 + $160 = $724.00
Laura’s earnings for that week were $724.00.
Answer: $604.00
Step-by-step explanation:
The other answers are paying commission on the whole amount of sales. The question says she earns 6% commission on all sales over $2,000. This would mean she earns commission on $7,400 ($9,400 - $2,000).
$7,400 X 0.06 = $444.00 in commission.
$444.00 + $160 (weekly pay) = $604.00 total earned

Answer:
7. C: 80
8. D: 100
9. C: 80
Step-by-step explanation:
each line equals 180
where H is at, has a 100 above it.
that equals one angle, which is 100. That line has 2 angles at equal 100 since they are one opposite sides of each other.
you subtract 180-100= 80. That's where you get ur 80 angle from. Hope this helps, I'm bad at explaining stuff
