solve the quadratic equations below.
3x2 + 22x + 35 = 0
Step-by-step explanation:
3x² + 22x + 35 = 0
(3x + 7)(x + 5) = 0
3x + 7 = 0
x = -7/3
or x+5 = 0
x = -5
Which graph shows a line with a slope 3/2?
Answer:
C I think, im not sure but sorry if im wrong
Step-by-step explanation:
Answer:
Graph B.Step-by-step explanation:
Graph A. is too low and graph C. is too steep.
Also we know that 3/2 is equal to 1.5. This means that it will be a little more than y = x. So if we look at point (2,2), the line is not at that point, but the line is a little higher.
An extended graphs can be seen below
in a city 30 °/• are female and 40°/. are males . what are remaining children
Answer:
30% are children.
Step-by-step explanation:
Females = 30%
Males = 40%
Therefore, children = 100% (total) - 30% + 40%
100 - 70
30%
in a city 30 °/• are female and 40°/. are males . what are remaining children?
SOLUTION:Given,
▶️ percentage of females = 30%
▶️ percentage of males = 40%
▶️ let the percentage of children be x.
Now,
▶️ x = 100% (total population) - 30% + 40%
▶️ x = 100% - 70%
▶️ x = 30% (Children population)
ANSWER:The population % of children in a city is 30%.

1. Multiply the 1st terms in bracket 1 and the 1st term in bracket 2:
(x × x)
2. Multiply the 1st term in bracket 1 and the 2nd term in bracket 2:
(x × 9)
3. Multiply the 2nd term in bracket 1 and the 1st term in bracket 2:
(-6 × x)
4. Multiply the 2nd term in bracket 1 and the 2nd term in bracket 2:
(-6 × 9)
5. You'll get the answer:
(x^2 + 9x - 6x - 54)
(x^2 + 3x -54)

y=-8 y=-2-12
Answer:
For the first one your first point is going to be on (0, -8) and will be a continuous horizontal line.
For the second equation the first point will be on (0, -12)
you want to go down two points and go to the right once point so (1, -14), (2,-16), (3,-18)
you also want to go up two points and to the left once so (-1, -10), (-2, -8), (-3, -6) and so on

hope this helps :) have a nice day !!
**please let me know if this was wrong**
Answer:
1) In the second step, it was supposed to multiply 9 and 2 and 36 by 3 instead of adding 9 and 3 to each other because multiplication and division comes before adding, according to pemdas.
2) In the second step, they were supposed to multiply 6 and 4 instead of subtracting 27 and 6 because multiplication comes before subtraction, according to pemdas.
3)
(43 - 20) - 2 · 5
43 - 20 = 23
23 - 2 · 5
2 · 5 = 10
23 - 10 =
13
4) 81 ÷ (13 - 4)
13 - 4 = 9
81 ÷ 9
81 ÷ 9 =
9
5) 7 · 8 - 3 · 6 + 1
7 · 8 = 56
3 · 6 = 18
56 - 18 + 1
56 - 18 = 38
38 + 1 =
39
6)
7)
8)
Step-by-step explanation:
Section 1: Explain the error in each problem below.1) Pemdas says multiplication and division comes before adding, so you must solve the multiplication in the problem first before the addition.
2) Again, as pemdas says, multiplication comes first before subtraction, so you must solve the multiplication in the problem first before the sutraction.
Section 2: Simplify the following expressions.3) (43 - 20) - 2 · 5
Pemdas says to solve the parenthesis first.
43 - 20 = 2323 - 2 · 5Now multiplication comes next (because there's no exponents).
2 · 5 = 1023 - 10Now subtraction.
23 - 10 = 134) 81 ÷ (13 - 4)
Pemdas says to solve the parenthesis first.
13 - 4 = 981 ÷ 9Now division comes next.
81 ÷ 9 = 95) 7 · 8 - 3 · 6 + 1
Pemdas says to solve the multiplication first.
7 · 8 = 56 3 · 6 = 1856 - 18 + 1Now subtraction and addition.
56 - 18 = 3838 + 1 = 396)
Section 3: Insert grouping symbols to make the statements true.7)

How many numbers are reciprocals of themselves?
Answer:
2

10/9= 2/3xd
what is the value of D
Answer:
d=5/3x
Step-by-step explanation:
Let's solve for d.
(2/3x)(d)=10/9
Step 1: Divide both sides by (2x)/3.
2/3dx / 2x/3=10/9 / 2x/3
d=5/3x
