8х + 9y = 20
х= -3y
HELP ASAP
Answer:
x=4, y=-4/3. (4, -4/3).
Step-by-step explanation:
8x+9y=20
x=-3y
---------------
8(-3y)+9y=20
-24y+9y=20
-15y=20
y=20/-15
simplify
y=-4/3
x=-3(-4/3)=12/3=4
Answer:
Y=4/-3 X=4
Step-by-step explanation:
We must use substitution. If x is -3y, then we can either substitute all the x’s or y’s. I’ll substitute y.
8x+9y=20
8x+-3x=20
5x=20
x=4
x=-3y, so -3y=4. Y=4/-3

The 25 students in Mr. Martinez’s class vote on their favorite farm animal. 40% like pigs. How many students like pigs?
Answer:
10
Step-by-step explanation:
If you divide my number by "-5 and add -2, the result is -4. What's my number?
Answer:
10
Step-by-step explanation:
10/-5 = -2
-2+-2 = -4
Answer:
10
Step-by-step explanation:
First, arrange this word problem as an equation. Using N as the unknown number, we see:
(N/-5) + (-2) = -4
Next, we add -2 to both sides of the equation:
(N/-5) = -2
Now multiply both sides by -5:
N=10

- 4 ( x - 5 ) = 92
What is x?
Answer:
Let's solve your equation step-by-step.
−4(x−5)=92
Answer:
x=−18

Jerry buys t-shirts for $6 each and marks up the price by 45%.
How much profit does Jerry make from each t-shirt sold?
help pleaseee
Answer:
$2.70
Step-by-step explanation:
to find out he marks up each shirt by, just do 45% of 6 or 0.45 * 6 = $2.70
If Jerry buys a t-shirt for $6 and sells it for 45% more than she bought it, then jerry is selling them for $8.70 and making $2.70 for each t-shirt she sells, because 45% of 6 is 2.7
You can find this answer by multiplying the percentage by the number (.45 x 6)

Answer:
D. Neither
Step-by-step explanation:
Ok so,
lets plug in the ordered pairs to see if the answer matches up. It should look like this:
7 = -2 - 5
7 = -7 DOES NOT MATCH; INCORRECT
now lets do it with the other ordered pair
-7 = -4 -5
-7 = -9 DOES NOT MATCH; INCORRECT
hope this helps, have a good day!

What is the value of y?
Enter your answer in the box.
y =
Answer:
180-79-37=101-37=64
y=64 degrees
Answer:
y = 64
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the given angles and equate to 180
y + 37 + 79 = 180
y + 116 = 180 ( subtract 116 from both sides )
y = 64
What is the equation of a line that passes through the points 0,5 and 4,8 in slope intercept form
Answer:
y = 3/4 + b
Step-by-step explanation:
To get slope intercept form you need to have the y = then you need to find the slope which is y2 - y1 and x2 - x1, find the answer whether it be a fraction or a whole number. And since you don't know the y-intercept you mark the last integer as b, since you don't the answer. So it comes out to y = 3/4 + b
y = (3/4)x + 5
Using the two coordinates, you can find slope and y-intercept
y-intercept is 5, from the point (0,5)
slope is 3/4, from rise/run, and that 0 to 4 is 4, while 5 to 8 is 3.
Combine slope and y-intercept for slope intercept form
y = (3/4)x + 5
Find the slope of the line. Write your answer in simplest form.

Jake has a goal of riding his bike at least 60 miles. He rides at a rate of 12 miles per hour. Which inequality can Jake use to find h, the number of hours he should ride in order to meet or exceed his goal?
Answer:
[tex]12h\geq 60[/tex], [tex]h\geq 5[/tex]
Step-by-step explanation:
Speed of Jake [tex]=12[/tex] miles per hour
Let [tex]h[/tex] denotes the number of hours he should ride in order to meet or exceed his goal.
Distance travelled by Jake = Speed × Time = [tex]12h[/tex]
Jake has a goal of riding his bike at least 60 miles.
Therefore,
[tex]12h\geq 60[/tex]
[tex]h\geq \frac{60}{12} \\\\h\geq 5[/tex]
The Blue Shell's flight path is modeled by the equation:
y = -10x2 + 100x + 750
a) Fill in the table below. The points will be used to plot on the below graph to create a
parabola.
b) Based on the table, what is the maximum
Y у
height the blue shell reaches?
Answer:
1. I assume you just pick some arbitrary x and y numbers to plug in the equation. but if you answer part b and c first, part a might be easier for what values to choose.
2. if you do a quick browser search for how to find the max height of a parabola, then you can learn how to.
3. research on Browser. you can also just make y = 0.
vertex is max height, both zeros is just solving the equation for the x values. axis of symmetry is just the vertex point with a line through it.

Jacob has 17 yards of fabric. He uses 1 third of it to make a cape. How many yards of fabric does Jacob use for the cape? Solve on paper. Write your answer as a mixed number. 17 yards ? Jacob uses yards of fabric for the cape
Answer:
The mixed number is 5 2 ÷ 3
Step-by-step explanation:
The computation of the number of yards of fabric does Jacob use is shown below:
Given that there is 17 yards of fabric
And, it used one third of it
So the number of yards would be
= 17 ÷ 3
= 5 2 ÷ 3
Hence, The mixed number is 5 2 ÷ 3
